Gratifications of Using Facebook, Twitter, Instagram, or Snapchat to Follow Brands:
The Moderating Effect of Social Comparison, Trust, Tie Strength, and Network Homophily on
Brand Identification, Brand Engagement, Brand Commitment, and Membership Intention
Abstract
Applying uses and gratifications theory (UGT), this study examined consumers’ use of one of
four social networking sites (SNSs): Facebook, Twitter, Instagram, or Snapchat, for following
brands, and their influence on brand community-related outcomes. Results (N = 297) indicated
Snapchat users scored highest for passing time, sharing problems, and improving social
knowledge, while Instagram users scored highest for showing affection, following fashion, and
demonstrating sociability. Twitter users had highest brand community identification and
membership intention, while Instagram users had highest brand community engagement and
commitment. Attention to social comparison, SNS trust, tie strength, and homophily also
significantly moderated the relationship between frequent use of each SNS to follow brands, and
brand community-related outcomes. Implications for future research on SNS users’ goal-directed
consumption behaviors are discussed.

1. Introduction
Social networking sites (SNSs) enable users to create personal profiles, articulate their
identities, connect with other users and brands, and view, share, upload and comment on photos,
messages, videos and other content posted on their newsfeeds (boyd & Ellison, 2007; Phua & Jin,
2011). SNSs are becoming increasingly ubiquitous in the everyday lives of people worldwide.
Among the most popular SNSs as of March 2016 are Facebook (1.56 billion active users),
Instagram (400 million active users), Twitter (320 million active users), and Snapchat (200
million active users) (Statista, 2015). Additionally, a 2015 industry report by Social Media
Examiner found that over 96% of businesses use SNSs to market their brands and products, due
to their ability to increase brand exposure, attract website traffic, develop loyal fans, and gain
marketplace intelligence (Stelzner, 2015). At the same time, consumers are increasingly using
SNSs to find out about brands and products (Laroche, Habibi, Richard, & Sankaranarayanan,
2012; Lipsman, Mudd, Rich, & Bruich, 2012). Consumers also integrate two or more SNSs as
part of their daily activities (Quan-Haase & Young, 2010) and access these SNSs on their mobile
devices (Lenhart, Duggan, Perrin, Stepler, Rainie, & Parker, 2015), allowing marketers more
touch-points to reach their consumers. Social media activities for a brand can foster the
consumer base of the brand (Xie & Lee 2015) and engagement in social media brand
communities increases consumers’ purchase expenditures (Goh, Heng, & Lin, 2013). Millions of
companies have set up Facebook pages for brand communication purposes and the popularity of
social media necessitates theoretical understanding of how social media exposures influence
brand-related outcomes (Xie & Lee, 2015).
In light of the exponential growth of SNSs and the integral role social media platforms
play in brand communication (Xie & Lee, 2015; Goh, Heng, & Lin, 2013), this study aims to
3
provide theoretical explanations for “why” people use SNSs and further elucidate the key
motivations for using different SNS platforms in the context of brand communities. To this end,
the current research draws from uses and gratification theory (UGT) given the relevance of the
theory to the assumption of media users as “active communicators” instead of passive recipients
of media forms and contents (Rubin, 2002).
Approaching the intersection between consumers’ use of multiple SNSs to find out about
brands and the utility of different SNSs for social media marketing, this study applies UGT (Katz,
Blumler, & Gurevitch, 1973) to examine consumers’ use of several top SNS platforms to follow
brands, gratifications gained from using them, and their influence on brand community-related
outcomes. Drawing from UGT and building upon previous empirical findings (Quan-Haase &
Young, 2010), the present study posited that frequent users of Facebook, Twitter, Instagram, and
Snapchat would derive different gratifications from their use (passing time, showing affection,
following fashion, sharing problems, demonstrating sociability, and improving social
knowledge) (Quan-Haase & Young, 2010), and also have different impacts on brand communityrelated outcomes (identification, engagement, commitment, and membership intention). The
relationship between SNS use and brand community-related outcomes would also be moderated
by several intervening variables (e.g., attention to social comparison, SNS trust, tie strength, and
network homophily). Overall, the study offers insights into the utility of different SNS platforms
for marketing and their influences on consumers’ perceptions of brands they follow.
2. Literature Review
2.1. Social Networking Sites (SNSs) and Brands
A major advantage of SNSs over more traditional media (e.g., radio, television) is their
capacity for greater user interactivity. When SNS users “like” or “follow” a brand, they will
4
receive updates and posts by the brand on their newsfeed. The users can then “like”, share, or
comment on the post, which would further propagate it on their friends’ newsfeeds, whose own
interactions with the post would, in turn, be rebroadcast to their networks. Hence, brand content
is transmitted in SNSs at a much faster rate and to a much larger and more responsive audience
than most traditional media, but at a much lower cost (Qualman, 2013). As such, digital
marketers are increasingly incorporating SNSs as an indispensable part of their online brand
strategy by raising brand awareness, driving engagement, and increasing conversions for their
brands and products. Previous research on SNSs in consumer marketing found increased
consumer engagement with brands based on frequency and content of brand pages’ updates
(Colliander & Dahlen, 2011; Phua & Ahn, 2014; Tsai & Men, 2013), proliferation of usergenerated content (UGC) (Krishnamurthy & Dou, 2008; Vanden Bergh, Lee, Quilliam, & Hove,
2011), referrals and recommendations (Chatterjee, 2011), identification and membership in
brand communities (Christodoulides, Jevons, & Bonhomme, 2012; Kim, Sung, & Kang, 2014),
and celebrity-endorsed electronic word-of-mouth (eWoM) (Jin & Phua, 2014; Lee & Youn,
2009). Studies also examined motivations for engagement with SNS advertising content (Chi,
2011; Kwon, Kim, Sung, & Yoo, 2014; Muntinga, Moorman, & Smit, 2011; Taylor, Strutton, &
Thompson, 2012), suggesting that SNS users have various motivations (e.g., informationseeking, leisure, etc.) that influence their use of features within one SNS platform as well as
across different SNS platforms. The current study attempts to examine whether gratifications of
using SNSs significantly differ across four different SNS platforms (Facebook, Twitter,
Instagram, and Snapchat), each with unique interactive features and ways for consumers to
engage with branded content.
2.2. Uses and Gratifications Theory (UGT)
5
UGT (Katz et al., 1973) is a theoretical framework explaining how and why people
actively seek out different media to fulfill their specific needs and wants. UGT posits that the
gratifications users receive through the media they select, in turn, satisfy a variety of
informational, social, and leisure needs. Key assumptions of UGT are: consumers are goaldirected in their media selection behavior and actively interpret and integrate media messages,
including advertisements, within their everyday lives, so as to achieve optimal levels of
gratification for their needs and desires (Rubin, 1986). Studies applying UGT have found that
consumers actively seek out different media to fulfill their informational, entertainment, social,
and escapism needs, with media self-efficacy, habitual behavior, prior attitudes, self-regulation,
and other factors moderating their media selections (Dimmick, Chen, & Li, 2004; Ko, Cho, &
Roberts, 2005; LaRose & Eastin, 2004).
More recently, scholarly research has used UGT to examine consumers’ goal-directed
consumption behavior in the context of SNSs (e.g., Chi, 2011; Kwon et al., 2014; Muntinga et al.,
2011; Papacharissi & Mendelson, 2011; Taylor et al., 2012). In particular, two trends with
regards to SNS use among brand consumers have been identified: (1) the majority of consumers
simultaneously use more than one SNS platform because each has its unique features and
purposes, and; (2) consumers increasingly embrace SNSs as both a communication channel and
an informational tool that help them fulfill their informational, emotional, and social desires
when used in tandem (Lenhart et al., 2015; Quan-Haase & Young, 2010). To date, numerous
researchers have analyzed motives for using SNSs applying the UGT approach. For instance,
Gulnar, Balci, and Cakir (2010) proposed seven motives affecting YouTube and Facebook use:
self-expression, media drenching, passing time, information seeking, personal status updating,
relationship maintenance, and entertainment. Park, Kee, and Valenzuela (2009) found that four
6
primary needs (socializing, entertainment, self-status seeking, and information) were fulfilled
from participating in Facebook groups. Quan-Haase and Young (2010), meanwhile, compared
Facebook and instant messaging use, and found that Facebook users derived fun and knowledge
about social activities from its use, while instant messaging is more for relationship maintenance
and development. UGT sees a medium as a source of influence within the context of other
possible influences. The theory also underscores the role of social and psychological elements in
mitigating mechanistic effects and sees mediated communication as being socially and
psychologically constrained (Rubin, 2002). Applying the UGT framework to the context of
social media use, people may use Facebook to stay in touch with friends, Twitter to follow news
and trending topics, Snapchat to instantly share short videos with selected individuals, and
Instagram to easily filter and upload visual images (Figure 1). Differences in main features and
functions among key SNS platforms examined in this study are presented in Figure 1.
[Insert Figure 1 about here]
Due to the unique and different design and usability features of SNS platforms, as well as
users’ different social psychological motivations to use each platform (Quan-Haase & Young,
2010), it can be hypothesized that individuals who most frequently use Facebook, Twitter,
Instagram, or Snapchat to follow brands, would differ significantly on six gratifications derived.
H1: SNS users who most frequently use Facebook, Twitter, Instagram, or Snapchat for
following brands, will differ significantly on six gratifications of SNS use: (a) passing
time, (b) showing affection, (c) following fashion, (d) sharing problems, (e)
demonstrating sociability, and (f) improving social knowledge.

2.3. SNS Brand Communities
A brand community is defined as “a specialized, non-geographically bound community,
based on a structured set of social relationships among admirers of a brand” (Muniz & O’Guinn,
2001, p. 412). In online brand communities, members often exhibit shared consciousness, rituals
and traditions, and a sense of moral responsibility, with many Internet users assuming
memberships in multiple brand communities, and managing their personal and social identities
through these memberships (Muniz & Schau, 2007). Similarly, on SNSs, consumers are
motivated to join brand communities to fulfill their social and identification needs. SNS brand
communities include groups centered around particular brands and products, as well as brand
pages which allow SNS users to “like” or “follow” brands and brand updates, as well as
comment and share these posts (Chi, 2011; Tsai & Men, 2013). Due to the ability to craft brand
messages that can be propagated by SNS users in a viral manner through their social networks on
various SNS platforms, brand pages are becoming an increasingly important part of digital
advertising and marketing strategies (Qualman, 2013). Brand pages not only allow consumers
with common brand interests to engage in communal activities, but also serve as a way for these
consumers to define their personal and social identities based on different brands they “like” or
“follow” on SNSs. Many brand pages also allow followers to engage in community activities,
including participating in contests, creating and sharing UGC such as videos and pictures, and
getting promotional offers.
Previous research on Internet-based brand communities has found that members establish
shared connections and a collective identity through their common interest in particular brands,
even in communities with a lack of social interaction among members (Algesheimer, Dholakia,
& Herrmann, 2005; Carlson, Suter, & Brown, 2008). Through identifying with others in the
8
brand community and conforming to group norms with regards to their consumption habits,
individuals satisfy their own intrinsic utilitarian (e.g., finding information about brands) and
hedonic (e.g., experiencing sensory pleasure through brands) consumption goals, while also
integrating the brand community as part of their identity on the SNS (Muniz & Schau, 2007).
Individuals who identify strongly with brand communities also develop stronger brand trust
(Hung, Li, & Tse, 2011), are more easily persuaded by brand messages (Kilambi, Laroche, &
Richard, 2013), and are more likely to share brand messages with others (Kim et al., 2014).
Additionally, consumers who are more engaged with brand communities are more likely to
follow the community rules, participate in brand-related activities, and exhibit higher brand
loyalty over a longer period of time (Hollebeek, Glynn, & Brodie, 2014; Kwon et al., 2014).
Moreover, when consumers are highly committed to a brand community, they are more likely to
purchase the brand’s products (Kilambi et al., 2013; Muniz & Schau, 2007; Scarpi, 2010).
Consumers with higher membership intention also visit brand pages more regularly, actively
upload UGC, spread eWoM, and stay on as brand “followers” for a longer period of time (Jin &
Phua, 2014; Sung, Kim, Kwon, & Moon, 2010). It can be hypothesized, therefore, that
individuals who most frequently use Facebook, Twitter, Instagram, or Snapchat to follow brands,
and who are members of brand communities on these SNS platforms, would differ significantly
on brand community-related outcomes.
H2: SNS users who most frequently use Facebook, Twitter, Instagram or Snapchat for
following brands, would differ significantly on brand communities with regard to users’:
(a) brand identification, (b) brand engagement, (c) brand commitment, and (d)
membership intention.

2.4. Attention to Social Comparison, SNS Trust, Tie Strength, and Homophily
Attention to social comparison refers to a person’s awareness of and sensitivity to the
reactions of others with regards to his/her own behavior (Lennox & Wolfe, 1984). Social
comparison with others within one’s social groups is a self-enhancement strategy that enables an
individual to raise his/her self-esteem through evaluating oneself with significant reference
groups. Attention to social comparison plays a significant role in influencing consumer
purchases and usage of peer-endorsed brands (Bearden & Rose, 1990; Chan & Prendergast, 2008;
Mandel, Petrova, & Cialdini, 2006). On SNSs, due to the ability of users to view brands and
products followed and/or liked by others within their social networks, as well as posts and
comments uploaded by peer consumers on brand pages, social comparison may have a
significant effect on consumers’ perceptions of brand communities (Kim et al., 2014; Sung et al.,
2010).
Additionally, SNS trust, tie strength, and network homophily, have a strong effect on
SNS users’ engagement with brand communities, and propensity to seek, give, and pass along
opinions about brands on the sites (Chu & Kim, 2011; Shan & King, 2015). SNS trust refers to
users’ willingness to rely on others in whom they have confidence (Moorman, Deshpande, &
Zaltman, 1993). Tie strength is the degree to which bonds among SNS members are strong or
weak (Mittal, Huppertz, & Khare, 2008). On SNSs, members derive bridging social capital with
acquaintances and distant others (Jin & Phua, 2014) and bonding social capital with close friends
and family (Phua & Jin, 2012). A study by Ellison, Steinfield and Lampe (2007) found that
intensity of Facebook use led to greater bridging social capital, but not bonding social capital.
Intensity of SNS use therefore did not necessarily increase trust nor tie strength, since bridging
10
social capital involves loose and weak friendship ties with low levels of trust but greater ability
for diffusion of new information (Granovetter, 1973). Homophily refers to the degree of
similarity among SNS network connections based on their beliefs, values, social status, and
interests (McPherson, Smith-Lovin, & Cook, 2001), with brand messages propagated within
homogeneous networks (Liu-Thompkins, 2012). When group members are homogeneous,
reference group influence becomes strong since similar users tend to interact frequently and
develop strong ties (Brown & Reingen, 1987). Homogeneous users within SNS-based brand
communities have more opportunity to exchange brand-related information and are more likely
to identify with the group members. When message senders (SNS posters) and receivers (SNS
viewers) in brand communities are more homogeneous, the information exchanged and shared is
likely to be perceived as more credible and trustworthy. Furthermore, a marketing stimulus that
focuses attention on consumers’ identification with a reference group and is relevant to that
identification elicit more positive responses (Reed, 2004). Based on these empirical findings and
theoretical rationales, it can be hypothesized that attention to social comparison, SNS trust, tie
strength, and network homophily would moderate the relationship between consumers’ SNS use
and brand community-related outcomes.
H3: The relationship between consumers’ brand-related participation in their most
frequently used SNS for following brands (Facebook, Twitter, Instagram or Snapchat),
and brand community-related outcomes (identification, engagement, commitment, and
membership intention) would be moderated by (a) attention to social comparison, (b)
SNS trust, (c) SNS tie strength, and (d) SNS homophily.

3. Methods
3.1. Participants
College students (N = 305) enrolled at a major university in the United States participated
in the study for extra credit. A total of 252 (82.6%) were female, while 53 (17.4%) were male.
For ethnicity, 229 (75.1%) were White, 28 (9.2%) were African-American, 28 (9.2%) were
Asian, 10 (3.3%) were Latino/Hispanic, 5 (1.6%) were Mixed, and 5 (1.6%) were Other. For
year in school, 23 (7.5%) were freshmen, 92 (30.2%) were sophomores, 116 (38.0%) were
juniors, 71 (23.3%) were seniors, and 3 (1.0%) were graduate students. For annual household
income, 90 (29.5%) earned less than $20,000, 12 (3.9%) earned $20,000-$40,000, 40 (13.1%)
earned $40,000-$60,000, 42 (13.8%) earned $60,000-$80,000, 36 (11.8%) earned $80,000$100,000, and 85 (27.9%) earned more than $100,000. Mean participant age was 20.3 years old
(SD = 1.25).
3.2. Procedure
An online questionnaire created using Qualtrics was posted to the college’s research
participation pool. At the beginning of the questionnaire, participants were first asked to select
only one SNS from a drop-down list (including Facebook, Twitter, Instagram and Snapchat) that
they most frequently used for following brands, and to answer all subsequent questions based on
their use of this one specific SNS. By doing this, we ensured that the SNS chosen by each
participant was the one that they most frequently used for acquiring brand-related information
and content, and participating in brand-related communities.
3.3. Measures
All measures were drawn from previously used scales that have been empirically
validated in published research. Gratifications of SNS use were assessed using six sub-scales
12
modified from Quan-Haase and Young (2010): passing time, affection, fashion, sharing
problems, demonstrating sociability, and improving social knowledge, on 7-point Likert scales,
ranging from “strongly disagree” to “strongly agree”. Passing time (9 items) included “to kill
time” and “to get away from pressures and responsibility” (Cronbach’s
= .85). Affection (5
items) included “to thank people” and “to let people know I care about them” (Cronbach’s
.87). Fashion (3 items) included “to look stylish” and “to look fashionable” (Cronbach’s
=
= .83).
Sharing problems (3 items) included “to forget about my problems” and “because I need
someone to talk to or be with” (Cronbach’s
= .79). Demonstrating sociability (3 items)
included “to make friends” and “to meet new acquaintances” (Cronbach’s
= .81). Improving
social knowledge (1 item) included “to know what’s going on with other people”.
To measure brand-related participation in the most frequently used SNS for following
brands, we included seven items modified from Rosen, Carrier, and Cheever (2013), on 7-point
Likert scales ranging from “not at all” to “frequently”. Items included “how often do you read
postings by brand pages on the SNS?” and “how often do you browse profiles and photos of
brand pages on the SNS?” (Cronbach’s
= .84). Brand community identification, engagement,
commitment, and membership intention were assessed using items modified from Sung et al.
(2010) on 7-point Likert scales ranging from “strongly disagree” to “strongly agree”.
Identification (5 items) included “I see myself as part of this brand community” and “I am very
attached to this brand community” (Cronbach’s
= .89). Engagement (4 items) included “I am
motivated to participate because I am able to reach personal goals” and “I am motivated to
participate because I can support other members” (Cronbach’s
= .90). Commitment (2 items)
included “I am proud to belong to this brand community” and “I feel a sense of belonging to this
brand community” (Cronbach’s
= .79). Membership intention (3 items) included “I intend to
13
stay on as a follower of this brand community” and “I plan to regularly visit this brand
community” (Cronbach’s
= .80).
To measure attention to social comparison, we used 13 items modified from Lennox and
Wolfe (1984) on 7-point Likert scales, ranging from “strongly disagree” to “strongly agree”.
Items included “I actively avoid wearing clothes that are not in style” and “At parties I usually
try to behave in a manner that makes me fit in” (Cronbach’s
= .85). Meanwhile, SNS trust, tie
Strength and homophily were measured using items modified from Chu and Kim (2011), on 7point Likert scales ranging from “strongly disagree” to “strongly agree”. Trust (3 items) included
“I trust my friend connections on this SNS”, and “I have confidence in my friend connections on
this SNS” (Cronbach’s
= .84). SNS tie strength (3 items) included “I feel very close to my
friend connections on this SNS” and “I communicate frequently with my friend connections on
this SNS” (Cronbach’s
= .83). SNS homophily (3 items) included “My friend connections on
this SNS think like me” and “My friend connections on this SNS behave like me” (Cronbach’s
= .86).
4. Results
4.1. SNS Use
For SNS most frequently used to follow brands, 116 (38.0%) answered Instagram, 93
(30.5%) answered Facebook, 60 (19.7%) answered Twitter, 28 (9.2%) answered Snapchat, 6
(2.0%) answered Tumblr, 1 (.4%) answered Pinterest, and 1 (.4%) answered Google+. For main
device to log in to the SNS, 241 (79.0%) used smartphones, 55 (18.0%) used laptops, 5 (1.6%)
used desktops, and 4 (1.3%) used tablets. These findings were consistent with a Pew Research
Center report on teenagers, SNS and technology use (Lenhart et al. 2015). Mean time as a
member of the SNS most frequently used was 52 months (SD = 24.9); mean time per week spent
14
using the SNS was 161 minutes (SD = 90.9); mean number of friends on the SNS was 480 (SD =
219.5); mean number of brands followed on the SNS was 39 (SD = 70.6). For the final data
analysis, the eight participants who reported using Tumblr, Pinterest or Google+ most frequently
for following brands were excluded, leaving 297 total participants who reported using Facebook,
Twitter, Instagram or Snapchat more frequently for following brands.
4.2. Gratifications of Using SNSs
A one-way MANOVA was conducted to examine gratifications of using SNSs (passing
time, showing affection, following fashion, sharing problems, demonstrating sociability, and
improving social knowledge) by SNS platform most frequently used to follow brands (Facebook,
Twitter, Instagram or Snapchat). Results revealed a significant multivariate main effect by SNS
platform most frequently used to follow brands (Wilks’ λ = .757, F (18, 815) = 4.68, p < .001,
partial η2 = .089, observed power = 1.00). Given the significance of the overall test, univariate
ANOVA results were examined with the p-value set at < .0125 to control for Type I error.
Significant univariate main effects by SNS platform were obtained for “passing time” [F (3, 293)
= 5.21, p < .001, partial η2 = .051, observed power = .925]; “showing affection” [F (3, 293) =
5.17, p < .001, partial η2 = .050, observed power = .923]; “following fashion” [F (3, 293) =
11.55, p < .001, partial η2 = .106, observed power = 1.00], “sharing problems” [F (3, 293) =
5.60, p < .001, partial η2 = .054, observed power = .942] “demonstrating sociability” [F (3, 293)
= 12.86, p < .001, partial η2 = .116, observed power = 1.00], and “improving social knowledge”
[F (3, 293) = 5.98, p < .001, partial η2 = .058, observed power = .956] . Levene’s tests of equality
of error variances were insignificant for all dependent measures, hence Scheffe post-hoc tests
were used to compare pairwise group means.
15
Scheffe post-hoc tests revealed that for “passing time,” significant differences were
observed between Snapchat and Facebook use (p < .01), Instagram and Facebook use (p < .001),
and Twitter and Facebook use (p < .01). Mean score for “passing time” was highest on Snapchat
(M = 5.46, SD = .92), followed by Instagram (M = 5.39, SD = .82), Twitter (M = 5.38, SD = .91),
and Facebook (M = 4.93, SD = 1.09). For “showing affection,” significant differences were
observed between Instagram and Twitter use (p < .01), Facebook and Twitter use (p < .01), and
Snapchat and Twitter use (p < .01). Mean score for “showing affection” was highest on
Instagram (M = 4.13, SD = 1.16), followed by Facebook (M = 4.11, SD =1.25), Snapchat (M =
4.05, SD = 1.33), and Twitter (M = 3.44, SD = .97). For “following fashion,” significant
differences were observed between Instagram and Facebook use (p < .001), Instagram and
Twitter use (p < .001), and Snapchat and Twitter use (p < .01). Mean score for “following
fashion” was highest on Instagram (M = 4.43, SD = 1.42), followed by Snapchat (M = 4.17, SD =
1.62), Facebook (M = 3.58, SD=1.55), and Twitter (M = 3.21, SD = 1.19). For “sharing
problems,” significant differences were observed between Snapchat and Twitter use (p < .01),
Facebook and Twitter use (p < .01), and Instagram and Twitter use (p < .01). Mean score for
“sharing problems” was highest on Snapchat (M = 4.20, SD = 1.66), followed by Facebook (M =
3.96, SD = 1.67), Instagram (M = 3.62, SD = 1.74) and Twitter (M = 2.99, SD = 1.07). For
“demonstrating sociability,” significant differences were obtained between Instagram and
Twitter (p < .001), Facebook and Twitter use (p < .001), and Snapchat and Twitter use (p <
.01). Mean score for “demonstrating sociability” was highest on Instagram (M = 4.72, SD =
1.53), followed by Facebook (M = 4.45, SD = 1.71), Snapchat (M = 4.39, SD = 1.72), and
Twitter (M = 3.16, SD = 1.48). For “improving social knowledge,” significant differences were
observed between Snapchat and Facebook use (p < .01) and Twitter and Facebook use (p <
16
.01). Mean score for “improving social knowledge” was highest on Snapchat (M = 5.96, SD =
1.20), followed by Twitter (M = 5.85, SD = 1.29), Instagram (M = 5.48, SD = 1.13), and
Facebook (M = 5.18, SD = 1.29).

4.3. Brand Community Outcomes
A one-way MANOVA was conducted to examine brand community outcomes
(identification, engagement, commitment, and membership intention) by SNS platform most
frequently used for following brands (Facebook, Twitter, Instagram or Snapchat). Results
revealed a significant multivariate main effect by SNS platform most frequently used for
following brands (Wilks’ = .772, F (12, 768) = 6.56, p < .001, partial η2 = .082, observed
power = 1.00). Given the significance of the overall test, univariate ANOVA results were
examined with the p-value set at < .0125 to control for Type I error. Significant univariate main
effects by SNS platform were obtained for “brand community identification” [F (3, 293) = 22.89,
p < .001, partial η2 = .190, observed power = 1.00]; “brand community engagement” [F (3, 293)
= 24.13, p < .001, partial η2 = .190, observed power = 1.00]; “brand community commitment” [F
(3, 293) = 33.76, p < .001, partial η2 = .257, observed power = 1.00], and “brand community
membership intention” [F (3, 293) = 17.50, p < .001, partial η2 = .152, observed power = 1.00].
Levene’s tests of equality of error variances were insignificant, hence Scheffe post-hoc tests
were used to compare pairwise group means.
Scheffe post-hoc tests revealed that for “brand community identification,” significant
differences were obtained between Twitter and Facebook use (p < .001), Twitter and Instagram
use (p < .001), Twitter and Snapchat use (p < .001), Instagram and Facebook use (p < .01), and
Instagram and Snapchat use (p < .001). Mean score for “brand community identification” was
17
highest on Twitter (M = 5.15, SD = 1.13), followed by Instagram (M = 4.49, SD = 1.13),
Facebook (M = 3.90, SD = 1.18), and Snapchat (M = 3.37, SD = .81). For “brand community
engagement,” significant differences were observed between Instagram and Facebook use (p <
.001), Instagram and Snapchat use (p < .001), Twitter and Facebook use (p < .001), and Twitter
and Snapchat use (p < .001). Mean score for “brand community engagement” was highest on
Instagram (M = 5.21, SD = 1.22), followed by Twitter (M = 5.02, SD = .86), Facebook (M =
4.19, SD = 1.10), and Snapchat (M = 3.68, SD = 1.23). For “brand community commitment,”
significant differences were observed between Instagram and Facebook use (p < .001),
Instagram and Snapchat use (p < .001), Twitter and Facebook (p < .001), and Twitter and
Snapchat use (p < .001). Mean score for “brand community commitment” was highest on
Instagram (M = 5.61, SD = 1.16), followed by Twitter (M = 5.37, SD = .986), Facebook (M =
4.23, SD = 1.49), and Snapchat (M = 3.75, SD = .81). For “brand community membership
intention,” significant differences were observed between Twitter and Instagram use (p < .01),
Twitter and Facebook use (p < .001), Twitter and Snapchat use (p < .001), Instagram and
Facebook use (p < .001), and Instagram and Snapchat use (p < .001). Mean score for “brand
community membership intention” was highest on Twitter (M = 5.62, SD = .85), followed by
Instagram (M = 5.16, SD = .99), Facebook (M = 4.56, SD = 1.21) and Snapchat (M = 4.28, SD =
1.05).

4.4. Moderation Effects
To test the moderation effects proposed in H3, hierarchical multiple regression analyses
were conducted. To avoid potential high multicollinearity, each variable was centered, and
interaction terms were created between brand-related participation in the SNS most frequently
18
used for following brands and each potential moderator, and entered into model two of each set
of hierarchical regressions. For each potentially significant moderation effect, the PROCESS
macro for SPSS (Hayes, 2013), across 1000 bootstrap samples, was run on the centered terms to
examine the effect. Attention to social comparison significantly interacted with brand-related
participation in most frequently used SNS for following brands to influence brand community
identification [ R2 = .016, F (1, 293) = 5.29, p < .05,β = -.123, 95% CI [-.237, -.010], t (293)
= -2.14, p < .05], but not engagement [ R2 = .001, F (1, 293) = .380, p = .538], commitment
[ R2 = .009, F (1, 293) = 2.93, p = .09], and membership intention [ R2 = .007, F (1, 293) =
2.29, p = .131]. SNS site trust significantly interacted with brand-related participation in most
frequently used SNS for following brands to influence brand community identification, [ R2 =
.018, F (1, 293) = 5.40, p < .05,β = .126, 95% CI [.012, .239], t (293) = 2.18, p < .05], and
membership intention [ R2 = .022, F (1, 293) = 6.88, p < .01,β = .130, 95% CI [.038, .222], t
(293) = 2.78, p < .01], but not engagement [ R2 = .001, F (1, 293) = .319, p = .573] and
commitment [ R2 = .000, F (1, 293) = .004, p = .949]. Similarly, SNS tie strength significantly
interacted with brand-related participation in most frequently used SNS for following brands to
influence brand community identification [ R2 = .055, F (1, 293) = 17.65, p < .001,β = .135,
95% CI [.067, .203], t (293) = 3.90, p < .001] and membership intention [ R2 = .043, F (1, 293)
= 13.26, p < .001,β = .135, 95% CI [.067, .203], t (293) = 3.91, p < .001], but not engagement
[ R2 = .008, F (1, 293) = 2.29, p = .131] and commitment [ R2 = .003, F (1, 293) = .976, p =
.324]. Meanwhile, SNS homophily significantly interacted with brand-related participation in
most frequently used SNS for following brands to influence brand community commitment, [ R2
= .017, F (1, 293) = 5.10, p < .05,β = -.160, 95% CI [-.274, -.046], t (293) = -2.76, p < .01],
but not identification [ R2 = .007, F (1, 293) = 2.00, p = .158], engagement [ R2 = .003, F (1,
19
293) = .921, p = .338], and membership intention [ R2 = .006, F (1, 293) = 1.71, p = .191].

5. Discussion
5.1. Key Empirical Findings, Managerial Implications, and Theoretical Contributions
The results indicate that individuals who most frequently used Facebook, Twitter,
Instagram, or Snapchat to follow brands differ significantly on six gratifications of SNS use:
passing time (H1a), showing affection (H1b), following fashion (H1c), sharing problems (H1d),
demonstrating sociability (H1e), and improving social knowledge (H1f). Specifically, individuals
who used Snapchat most frequently for following brands scored highest on passing time, sharing
problems, and improving social knowledge, while individuals who used Instagram most
frequently for following brands scored highest on showing affection, following fashion, and
demonstrating sociability. Snapchat and Instagram are both photo and video messaging apps
gaining in popularity among millennials (Lenhart et al., 2015). On Snapchat, users set a time
limit for how long recipients can view their “snaps” before they are deleted while on Instagram,
users apply shaded filters to their photos before posting them to their profiles (Lenhart et al.,
2015). Individuals who used Snapchat most frequently for following brands score the highest on
passing time, followed by those who used Instagram, Twitter and Facebook most frequently,
indicating that they found Snapchat most useful for entertainment and relaxation purposes, as
well as being fun and a form of escapism from their everyday routines. Individuals who used
Snapchat most frequently for following brands also scored the highest on sharing problems,
followed by Facebook, Instagram, and Twitter. As such, users found Snapchat to be most helpful
when they need someone online to listen to them in order to forget their problems. Additionally,
20
individuals who used Snapchat most frequently to follow brands also felt that the site most
fulfilled their need for improving social knowledge, making them feel most involved with what’s
going on with other people, followed by those who most frequently used Twitter, Instagram and
Facebook. These findings are likely due to the synchronous and personal nature of Snapchat,
whereby users send photo or video “snaps” via their mobile devices and are able to receive
immediate, personal replies from recipients. Comparatively, on Facebook, Twitter, and
Instagram, one’s posts are less personal and more asynchronous, since posts can be seen by a
larger number of people over a longer period of time, with friends’ replies to one’s posts also
being broadcast publicly. As a result, users of these sites may not be as comfortable sharing
problems, and consequently, feel less involved with what’s going on in others’ lives, compared
to the more personal, intimate nature of Snapchat.
On the other hand, individuals who most frequently used Instagram for following brands
score the highest on showing affection, followed by Facebook, Snapchat and Twitter, indicating
that Instagram most fulfill users’ needs to thank people, let others know they care, offer help, and
show encouragement and concern (Quan-Haase & Young, 2010). Instagram was also rated the
highest on following fashion, with members using the site primarily as a style guide, compared
to Snapchat, Facebook, and Twitter. Additionally, individuals who used Instagram most
frequently for following brands also ranked the highest for demonstrating sociability, or making
friends of the opposite sex, meeting new acquaintances, and being least inhibited chatting to
strangers, followed by those who most frequently used Facebook, Snapchat, and Twitter. These
results may be explained by the fact that Instagram, being a visual image-based SNS primarily
for posting pictures with shaded filters, acts as a showcase for one’s style and fashion. At the
same time, Instagram users may also be less inhibited, since the visual nature of the SNS allows
21
them to view “like,” and “follow” other members whom they may not know in real life, but
interact with on the site through their pictures. Moreover, the uninhibitedness of Instagram users
may also lead to their greater showing of affection toward others, through commenting on
others’ pictures and using emoticons, compared to the other three SNSs.
More importantly and with regard to contributions to empirical findings about and data
on social media-related brand outcomes, the results indicate that level of brand-related
participation in the SNS most frequently used for following brands (Facebook, Twitter,
Instagram or Snapchat) resulted in significantly different levels of brand community
identification (H2a), engagement (H2b) commitment (H2c), and membership intention (H2d)
from the sites. Specifically, individuals who used Twitter most frequently for following brands
reported the highest brand community identification from the site, followed by those who most
frequently used Instagram, Facebook, and Snapchat for following brands As such, individuals
who use Twitter most frequently for following brands have the strongest attachment to brand
communities, sharing brand-related objectives and seeing themselves as part of the larger
community (Algesheimer et al., 2005; Carlson et al., 2008; Muniz & Schau, 2007). This may be
possible due to Twitter being a micro-blogging site where brands post multiple updates in real
time and allow followers to “retweet” these updates, search for brands using hashtags, and spread
eWoM using their own 140-character posts which are then re-broadcast to their followers’ feeds
(Jin & Phua, 2014). On Twitter, marketers are also best able to imbue brands with human
personalities, and therefore build strong identification with consumers (Kwon et al., 2014).
Individuals who used Twitter most frequently for following brands also reported the highest
brand community membership intention, followed by those who most frequently used Instagram,
Facebook and Snapchat for following brands. Individuals who used Twitter most frequently for
22
following brands are hence most likely to regularly visit brand pages they follow, stay on as
brand followers, create UGC, and spread eWoM (Chu & Kim, 2011; Jin & Phua, 2014). One of
the major functions of Twitter for SNS-based marketing is the ability for followers to retweet
brand messages. As Kim et al. (2014) found, Twitter users reported significantly higher
membership intention when performing retweeting behavior, consistent with the findings of the
current study whereby retweeting is analogous to a form of eWoM.
This study also found that individuals who most frequently used Instagram for following
brands reported highest brand community engagement, followed by those who most frequently
used Twitter, Facebook or Snapchat for following brands. Individuals who most frequently used
Instagram for following brands are therefore most likely to participate in brand-related activities,
follow community rules, and be loyal to brand they follow over a longer period of time
(Hollebeek et al., 2014). Since Instagram is a photo-sharing platform, whereby members post
pictures and short videos with different filters applied, brands are able to post their products’
graphic content in a visually pleasing and highly stimulating way (Lenhart et al., 2015). Thus, it
is possible that Instagram users would be more engaged with brands they follow on the site,
participate in brand-related activities, and have high brand loyalty. Furthermore, individuals who
most frequently used Instagram for following brands also exhibited the highest brand community
commitment, followed by those who most frequently used Twitter, Facebook, and Snapchat for
following brands. When one is committed to a brand community, he/she is more likely to feel a
sense of belonging and have higher brand purchase intention (Kilambi et al., 2013; Scarpi, 2010).
The results indicate that Instagram users show the greatest belongingness and pride in the brand
pages on which they participate. Consequently, this commitment to the brand community can
contribute to future intention to purchase the brand’s products (Jin & Phua, 2014; Muniz &
23
Schau, 2007). These empirical findings have tremendous managerial implications for effective
management of social media platforms for brand communication.
Another major finding of this study is that brand-related participation in the SNS most
frequently used for following brands (Facebook, Twitter, Instagram or Snapchat) significantly
interacted with several moderators to affect brand community identification, engagement,
commitment, and membership intention. Specifically, attention to social comparison (H3a)
moderated the relationship between brand-related participation in the SNS most frequently used
for following brands and brand community identification. For consumers with low attention to
social comparison, greater brand-related participation in the SNS most frequently used for
following brands led to higher brand community identification, whereas for those with high
attention to social comparison, greater brand-related participation in the SNS most frequently
used for following brands led to lower identification. Additionally, SNS trust (H3b) significantly
moderated the relationship between brand-related participation in SNS most frequently used for
following brands and brand community identification and membership intention. Consumers
with higher SNS trust increased their brand communication, identification, and membership
intention through increased brand-related participation in the SNS most frequently used for
following brands, while those with lower SNS trust decreased their identification and
membership intention if they participated more in the SNS most frequently used for following
brands. SNS tie strength (H3c) also significantly moderated the relationship between brandrelated participation in the SNS most frequently used for following brands and brand community
identification and membership intention. Consumers who perceived stronger ties to their SNS
friends increased their identification and membership intention as their brand-related
participation in the SNS most frequently used for following brands increased, while those who
24
perceived weaker ties to their SNS friends decreased their identification and membership
intention with increased brand-related participation in the SNS most frequently used for
following brands. Finally, SNS homophily (H3d) significantly moderated the relationship
between brand-related participation in the SNS most frequently used for following brands and
brand community commitment. Consumers with more homogeneous networks decreased their
brand community commitment when brand-related participation in the SNS most frequently used
for following brands increased, while those with more heterogeneous networks increased their
brand community commitment when brand-related participation in the SNS most frequently used
for following brands increased. These results indicate that many intervening factors affect the
relationship between a consumer’s brand-related participation in the SNS most frequently used
for following brands and his or her contributions to, and benefits derived from, brand
communities followed on the particular SNS (Chu & Kim, 2011; Kim et al., 2014). Overall, this
research advances our understanding of SNS users’ various motivations for using different social
media platforms to follow brands, thus providing brand manages with deeper insights into the
management of SNS platforms building upon the solid understanding of consumers’ motivations
and needs in the context of social media marketing. With regard to theoretical contributions, this
research not only empirically tests UGT in the novel domain of social media and brand
communities but also adds theoretical discussions on user habit and motivations across a variety
of social media platforms to existing UGT literature, thus contributing to the development of
UGT in computer-mediated brand communications.
5.2. Limitations and Implications
There are some limitations to the present study, which offer suggestions and implications
for future research. First, we asked participants to self-report their most frequently used SNS for
25
following brands, level of brand-related participation in the SNS most frequently used for
following brands, and perceived identification, engagement, commitment, and membership
intention, for brand pages they follow on the particular SNS. Although self-reports provide
accurate data about media use drawing from UGT (Rubin, 2002), future studies should access
actual SNS usage data using social monitoring programs, so as to establish greater
generalizability of the results. Second, the six gratifications included (passing time, showing
affection, following fashion, sharing problems, demonstrating sociability, and improving social
knowledge) were from one prior study (Quan-Haase & Young, 2010). Future studies should
further explicate SNS uses and gratifications through factor analysis and structural modeling
combining additional scales from other studies. Third, our study sample consisted of
undergraduate students, who have been found to be more active on newer SNSs like Snapchat
and Instagram (Lenhart et al., 2015), and as such, our results may be skewed towards this
particular population of millennials. To increase external validity of this line of research, future
studies should recruit participants from a wider age range, so as to obtain results most applicable
to the general SNS-using population. Fourth, we did not control for specific brands followed by
users on each SNS. It is possible that SNS users who follow hedonic versus utilitarian brands,
and brands in different product categories (e.g. fashion, automobiles, travel etc.) may derive
different brand community-related outcomes from their participation. Future studies should
compare SNS followers of one particular type of brand or product category across different SNS
platforms. Fifth, we did not examine other antecedents of purchase intention, such as brand
awareness and brand image, nor explore factors affecting SNS members’ following of or
using brand communities, which future studies should assess.
26
Our study also offers some practical implications for advertisers and marketers looking to
harness different SNS platforms to improve their branding. First, as our results strongly suggest,
SNS users derive significantly different gratifications from their frequent use of Facebook,
Twitter, Instagram, or Snapchat to follow brands. Those who used Snapchat most frequently for
following brands rated the SNS highest for passing time, sharing problems, and improving social
knowledge, while those who used Instagram most frequently for following brands rated it highest
for showing affection, following fashion, and demonstrating sociability. Advertisers should thus
match their brands/products to appropriate SNS platforms based on gratifications derived from
each site, so as to effectively reach their intended target audience. Second, those who used
Twitter most frequently for following brands had greatest brand community identification and
membership intention, while those who used Instagram most frequently for following brands had
greatest brand community engagement and commitment. As such, advertisers should upload
different content (e.g. pictures, videos, GIFs etc.) at different frequencies to their brand pages on
each platform, so as to maximize consumers’ brand-related outcomes. Third, our results also
suggest that advertisers should seek to win their brand followers’ trust and also strengthen their
ties to the brand community (e.g. through contests, encouraging UGC, and providing incentives,
etc.), in order to improve brand outcomes (Jin, 2013).
Applying UGT (Katz et al., 1973), this study examined SNS users’ goal-directed
consumption behaviors through their use of one of four popular SNS platforms (Facebook,
Twitter, Instagram, or Snapchat) for following brands, gratifications gained from each SNS,
impact on brand community-related outcomes, and moderators (attention to social comparison,
SNS trust, tie strength, and network homophily) influencing this process. Overall, this study
contributes to the current research literature on consumers’ brand-related activities on SNSs,
27
offering insights into the utility of different SNSs for brand-related marketing outcomes, through
their attendant influences on consumers’ perceptions of brands they follow, from a marketing
communication perspective.
