We investigated the effect of fluctuations in negative and positive affect on momentary sexual motivation in a sample of women and men in a steady relationship (n = 133). Sexual motivation was regarded as the aggregate of sexual desire, subjective sexual arousal and openness to sexual contact. Experience sampling methodology was used to collect up to 70 measurements per participant over a period of seven consecutive days of sexual motivation, and negative and positive affect. Using multilevel analysis, we investigated cross-level interactions between affect and trait measures as specified in the dual control model (DCM). This model postulates sexually excitatory and inhibitory mechanisms as relatively independent systems that together can explain individual differences in sexual motivation and behavior. Results implicated that any intensification of feelings, positive or negative, was associated with a momentary increase in sexual motivation for participants more prone to sexual exc...

The analysis of change within subjects over time is an ever more important research topic. Besides modelling the individual trajectories, a related aim is to identify clusters of subjects within these trajectories. Various methods for analyzing these longitudinal trajectories have been proposed. In this paper we investigate the performance of three different methods under various conditions in a Monte Carlo study. The first method is based on the non-parametric k-means algorithm. The second is a latent class mixture model, and the third a method based on the analysis of change indices. All methods are available in R. Results show that the k-means method performs consistently well in recovering the known clustering structure. The mixture model method performs reasonably well, but the change indices method has problems with smaller data sets.

In the present study, we explore the proposed cyclic models for problematic hypersexuality (PH) that involve shame, self-esteem, and sexual desire. These cyclic models are characterized by temporal associations but have not been investigated previously with intensive longitudinal designs. In this study, we collected up to 70 measurements per participant within a period of seven consecutive days, which allowed us to investigate associations between fluctuations of shame, self-esteem, and sexual desire. Participants were divided in four subgroups: (1) women (n = 87); (2) men (n = 46) from a general population convenience sample; (3) men watching porn >2 times per week, showing non-problematic hypersexuality (NH; n = 10); and (4) men watching porn >2 times per week, experiencing PH (n = 11). Multilevel analyses, including cross-level interactions, were used to investigate between-group differences in intraindividual processes. Results showed that prior increases in shame forecast...

In this online cross-sectional survey study in a large community sample we investigated the associations between attachment-related relational needs, partner responsiveness, intimacy, and sexual desire, using structural equation modeling. Participants were heterosexual and non-heterosexual women and men. Intimacy and partner responsiveness correlated positively with sexual desire in all subsamples. Anxious attachment-related relational needs correlated positively with sexual desire. Avoidant attachment-related relational needs correlated negatively with sexual desire. Anxious and avoidant attachment-related needs, however, did not moderate the association between intimacy and sexual desire. Individuals with problems of low sexual desire may benefit from an emphasis in sex therapy on ways to increase (perceptions of) intimacy.

The tutorial aims to explain the basics of multilevel level models using visualizations. It is meant for students and researchers who are relatively new to multilevel analysis. By avoiding formula's as much as possible, the tutorial may in particular be useful for persons with statistical anxiety. Various simple models are explained by visualizing the predicted values from these models.

Background Many children and adolescents suffer from problematic levels of anxiety, but the multitude of these children do not receive an intervention. It is of importance to increase the accessibility and availability of child anxiety interventions, as to identify and treat anxious children early and successfully. Online platforms that include information, assessments and intervention can contribute to this goal. Interventions for child anxiety are frequently based on Cognitive Behavioral Therapy, because of its strong theoretical and empirical basis. However, the working mechanisms of Cognitive Behavioral Therapy in children are poorly studied. To our knowledge, mediation studies on child anxiety are non-existent regarding online Cognitive Behavioral Therapy. Methods We will aim at children aged 8–13 years with problematic anxiety. We recruit these children via the community setting, and refer them to our online platform ‘Learn to Dare!’ (in Dutch: ‘Leer te Durven!’), https://leer...

Purpose The purpose of this paper is to describe whether and how groups of nursing home residents respond to the interactive device “the CRDL”. The CRDL can translate touches between people into sounds. It recognises the type of touch and adjusts the produced sound accordingly. Design/methodology/approach This was as an observational explorative study. Responses were coded and analysed using an existing theoretical framework. Findings The CRDL creates an atmosphere of playfulness and curiosity. It lowers the threshold to touch, provides an incentive to touch and encourages experimentation with different types of touches on arms and hands. The sounds the CRDL produces sometimes trigger memories and provide themes to start and support conversation. Involving a (large) group of nursing home residents to interact with the CRDL is challenging. Research limitations/implications In order to more fully understand the potential of the CRDL, its use should be studied in different group and in...

Despite the use of art therapy in clinical practice, its appreciation and reported beneficial results, no instruments are available to measure specific effects of art therapy among patients with personality disorders cluster B/C in multidisciplinary treatment. In the present study, we described the development and psychometric evaluation of the Self-expression and Emotion Regulation in Art Therapy Scale (SERATS). Structural validity (exploratory and confirmatory factor analysis), reliability, construct validity and sensitivity to change were examined using two independent databases (n = 335; n = 34) of patients diagnosed with personality disorders cluster B/C. This resulted in a nine-item effect scale with a single factor with a high internal reliability and high test-retest reliability; it demonstrated discriminant validity and sensitivity to change. In conclusion, the SERATS is brief and content-valid and offers objective and reliable information on self-expression and emotion reg...

The majority of studies investigating associations between physical activity and mental health in adolescents have been cross-sectional in design. Potential associations between physical activity and mental health may be better examined longitudinally as physical activity levels tend to decrease in adolescence. Few studies have investigated these associations longitudinally in adolescents and none by measuring physical activity objectively. A total of 158 Dutch adolescents (mean age 13.6 years, 38.6 % boys, grades 7 and 9 at baseline) participated in this longitudinal study. Physical activity, depressive symptoms and self-esteem were measured at baseline and at the 1-year follow-up. Physical activity was objectively measured with an ActivPAL3™ accelerometer during one full week. Depressive symptoms were measured with the Center for Epidemiologic Studies Depression Scale (CES-D) and self-esteem was assessed with the Rosenberg Self-Esteem Scale (RSE). Results were analysed using struc...

In nursing homes, extreme sexual behavior is one of the most challenging behaviors in dementia. Despite this, however, there is no conformity in the literature regarding how to label and define this type of behavior. Examples of labels used include inappropriate sexual behavior, improper sexual behavior, sexually disinhibited behavior, or hyper sexuality. According to recent theoretical perspectives, extreme sexual behavior may be regarded as a part of disinhibited behavior or could be considered as an independent neuropsychiatric symptom. In this multicenter study, it was investigated whether there is a relationship between extreme sexual behavior and the typical neuropsychiatric symptoms seen in dementia. In 179 residents diagnosed with dementia, extreme sexual behavior was measured using an observation scale. Twelve neuropsychiatric symptoms were measured by the Neuropsychiatric Inventory. Multivariate analysis of covariance with gender showed that residents with observed extreme...

BACKGROUND Digital health promotion programs tailored to the individual are a potential cost-effective and scalable solution to enable self-management and provide support to people with excess body weight. However, solutions that are personalised, theory- and evidence- based and widely accessible are still limited. OBJECTIVE This study aimed to develop a digital behaviour change program, Choosing Health, that could identify modifiable predictors of weight loss and maintenance for each individual and utilise these to provide tailored support. METHODS We applied an Intervention Mapping protocol to design the program. This systematic approach to develop theory- and evidence-based health promotion programs consisted of 6 steps: development of (1) a logic model of the problem, (2) model of change, (3) intervention design and (4) production, (5) the implementation plan, and (6) evaluation plan. The decisions made during the Intervention Mapping process were guided by theory, existing evid...

This study aimed to assess the best combination of indicators of problematic hypersexuality (PH), in a survey (n = 58,158) targeting individuals wondering if they were sex addicted. The survey allowed for testing of criteria from three theoretical models used to conceptualize PH. Factor analyses for women and men yielded an interpretable grouping of indicators consisting of four factors. In subsequent logistic regressions, these factors were used as predictors for experiencing the need for help for PH. The factors Negative Effects and Extreme positively predicted experiencing the need for help, with Negative Effects as the most important predictor for both women and men. This factor included, among others, withdrawal symptoms and loss of pleasure. The Sexual Desire factor negatively predicted the need for help, suggesting that for the targeted population more sexual desire leads to less PH. The Coping factor did not predict experiencing the need for help. Outcomes show that a combin...

BACKGROUND: Threat-based (fear-appeal) interventions are often ineffective yet popular. The current paper reports the evaluation of an intervention that was designed to discourage using threatening communication and that targeted those responsible for this popularity (intervention developers, campaign leaders, policy makers, politicians, scientists and advertising professionals).METHODS: Of the 153 participants who started, 102 completed both the first phase and the six-week follow-up measurement of the within-subject experiment. In the first phase, participants rated hypothetical behavior change interventions in six health domains (e.g., smoking, alcohol), after which they were presented with an intervention targeting themselves, which provided evidence on the ineffectiveness of threatening communication as persuasive instrument. Participants then rated more hypothetical interventions immediately and after six weeks.RESULTS: The intervention decreased the effectiveness ratings of t...

Startende ondernemers zijn een snel groeiende groep in Nederland. Voor toezichthouders is het van belang dat zich bij deze groep compliance met de wet- en regelgeving ontwikkelt. Dit artikel geeft een overzicht van de relevante factoren bij het bevorderen van compliance bij startende ondernemers. In het bijzonder wordt de fiscale compliance beschouwd en aan de hand van de Tafel van Elf, een door het ministerie van Justitie ontwikkeld instrument om compliance te operationaliseren, toegepast op de ontwikkelingsfasen van ondernemingen. Belangrijkste conclusie is dat de diverse beleidsinstrumenten om compliance te bereiken zo vroeg mogelijk moeten worden ingezet. Daarnaast is het van belang dat het instrument past bij de ontwikkelingsfase van een onderneming.

Moderated mediation analysis assumes that the effect of a predictor on a dependent variable is mediated by one or more mediators and that the indirect paths in this mediation are moderated. Moderation can take place on the effect of the predictor on the mediators, or on the effect of the mediators on the dependent variable.In this tutorial we will show how the R function “gemm” from the “rosetta” package can be used to do a moderated mediation analysis.

The experience of emotional intimacy is assumed to play a particularly large role in maintaining sexual desire and partnered sexual activity in romantic relationships of longer duration. It is unclear whether the effect of intimacy on sexual contact between partners is direct or indirect, via its impact on sexual desire. Baumeister and Bratslavsky suggested that a certain increment in emotional intimacy causes a greater increment in sexual desire in men than in women. In the present study, we aimed to test the mediating role of sexual desire between perceived intimacy and sexual partner interaction and the gender effect as hypothesized by Baumeister and Bratslavsky. Experience sampling methodology in the participant's natural environment was used. At 10 quasi-random moments per day, during 7 consecutive days, 134 participants reported their feelings of emotional intimacy, sexual desire, and sexual activity. The direct effect of intimacy on sexual partner interaction was not sign...

ABSTRACT Purpose – The purpose of this paper is to examine the role of organizational justice in the context of Karasek’s job demand-control model. It is suggested that employees benefit from organizational justice in order to cope with high job demands. Furthermore, it is argued that justice perceptions are a precondition for the buffering role of job control with respect to job demands. Design/methodology/approach – A cross-sectional study on employees (n¼197) in nursing houses was used. The hypotheses were tested by hierarchal regression analysis. Findings – Results showed that organizational justice buffered for the positive effect of job demands on turnover intentions and for the negative effect of job demands on job satisfaction. Furthermore, the results showed that justice serves as an important precondition for the moderating role of job control on the effect of job demands on job satisfaction and turnover intentions. Justice appeared to strengthen the role of job control as a buffer for high job demands. Originality/value – The importance of organizational justice with respect to job design and personnel practices has been demonstrated. New is the finding that justice can strengthen the role of job control as a buffer for high job demands.
