Con el objetivo de conocer la practica, metodologia y criterios de decision de los psicologos forenses espanoles con experiencia en casos de familia, 66 psicologos forenses espanoles (margen de error ±.06) respondieron a una adaptacion espanola del cuestionario para evaluacion de las practicas en la evaluacion de la guarda y custodia de los hijos de Keilin y Bloom (1986) y Ackerman y Ackerman (1997). Los resultados mostraron que a los participantes les resultaba indiferente trabajar a peticion del juzgado o de un parte; que la evaluacion incluia la revision documental, la entrevista individual con cada progenitor, la entrevista individual con cada menor, la aplicacion de prueba...

The two first sections deal with basic procedures to use the program as a spreadsheet, organise and create a data matrix. Sections three, four and five describe how to proceed in order to carry out a descriptive analysis of qualitative and quantitative variables, both from a univariant and bivariant approach. In the rest of sections reference is made to the necessary instructions to perform different tests under the framing of inferential statistics, as well as how to calculate statistical significance from different statistical figures. El present document pretén donar les eines bàsiques per tal que l'usuari pugui realitzar una anàlisi estadística bàsica a partir del full de càlcul Microsoft Excel. Ens els dos primers apartats es fa referència als procediments bàsics per utilitzar el programa...

This concept of distance is constantly used and re-used as a source of evidence in the search for significant contrasts with respect to models of theoretical probability. This paper proposes a number of ideas regarding the use of new distance indicators related to statistics that rely less heavily on parametric assumptions, in particular, the use of median confidence intervals. We have simulated via EXCEL different data samples for a design of two independent groups under 15 different conditions in two different situations: mean equality and mean differences. The results showed the high sensitivity of the comparison of the confidence intervals, especially if a strict decision criterion is used. However, we did not obtain good results for sensitivity. In fact, in some cases, the comparison of the confidence intervals of the mean worked better than tho...

In this chapter, the authors make a revision of the concept and an empirical approach to the possible reasons of student absenteeism through multivariate analyses—which the students themselves believe to be justified—and those offered by the faculty members in the case of the authors’ big school (with nine studies and 12,000 students), of the authors’ university (with 70,000 students), in the authors’ country. The analysis was carried out on two samples (1,161 students and 181 professors), which indicates that the reasons offered by each population are not the same. Through a cluster analysis, it is possible to identify six student performance profiles, which sheds some light on understanding this fact and the opportunity to suggest some ways of action.

A body of studies has stated that the attitude of undergraduates when resolving statistical problems can be affected by problem displaying methods. Our paper reports on the development of novel and accessible problems designed to compare the basic processes of statistical reasoning using two different methods of presentation:Verbal-numerical versus graphical. Therefore, the main purpose of the current study is to estimate the goodness and reliability of those problems. Thus,we carried out two pilot studies in Italy and Spain, respectively. In the first study, 95 undergraduate students from the University of Cagliari (Italy) were presented with eleven pairs of simple statistical problems, homologous for verbal-numerical and graphical formats. Hence, according to the outcomes, we modified and improved the structure of our problems in order to present the revised version to 148 undergraduate students of the University of Barcelona (Spain). Each undergraduate was asked to solve the paired problems presented in verbal-numerical and graphical format, so that the presentation order of the trials was counterbalanced for all the participants. The results suggested which problems are suitable to assess the basic processes underpinning the statistical reasoning. Furthermore, by analysing the open responses on reasoning leading to the solution of the above mentioned problems, we were able to understand which items were misunderstood byour participants in order to reformulate them. Lastly, we discuss themethod used to articulate the new items and the direction for future research.

Research reports how students' ability to solve problems (including statistical problems) can be influenced by exhibiting proofs. In this work we aim to contrive an original and easy instrument able to assess statistical reasoning on uncertainty and on association, regarding two different forms of proof presentation: pictorial-graphical and verbal-numerical. We have conceived eleven pairs of simple problems in the verbal-numerical and pictorial-graphical form and we have presented the proofs to 47 undergraduate students. The purpose of our work was to evaluate the goodness and reliability of these problems in the assessment of statistical reasoning. Each subject solved each pair of proofs in the verbal-numerical and in the pictorial-graphical form, in different problem presentation orders. Data analyses have highlighted that six out of the eleven pairs of problems appear to be useful and adequate to estimate statistical reasoning on uncertainty and that there is no effect due to the order of presentation in the verbal-numerical and pictorial-graphical form.

The transition from high school to college requires a student to take a succession of decisions that will shape their future. For this reason, knowledge of the motivations of the students, their family, and their personal environment, to choose a particular degree and/or university to pursue their higher studies, would allow universities to efficiently adjust their recruitment strategies. In this article, a study was developed based on a structural equation model of the access to the Spanish Public University System (SUPE), which can help with supply and demand problems, recruitment actions and policies, and other strategic decisions. This was done through an extensive survey of first-year students of Spanish universities. The results allowed us to obtain the parameters of the model, which showed that the fit between the model and the data obtained were excellent at a global...

Matched by age and gender, each 40-subject sample includes patients with differential diagnosis of schizophrenia. One sample was taken from the Barcelona Hospital network (Spain) and the other one from the Hospital Civil Universitario of Guadalajara (Mexico). Several demographic and clinical variables were evaluated and the Health Related Quality of Life Scale (HRQLS) was conducted on all the subjects. The HRQLS was adapted to Spanish (Rodriguez, et al., 1995). The results confirmed the factor structure studied and they showed no special differences in the total score of the HRQLS. However, an important effect was found when analyzing the results separately for the three factors: Interpersonal Relationship (IR1), Instrumental Resources (IR2) and Intrapsychic Foundation (IF), or in the items of the Intrapsychic Foundations factor. Given these diffe...

It has been hypothesized that the connectivity patterns in this network are related to different cognitive states. Purpose: In this study, we explored the relationship that can be estimated between these functional connectivity patterns of the DMN with the Quality-of-Life levels in people with Down syndrome, since no relevant data has been provided for this population. Methods: 22 young people with Down syndrome were evaluated; they were given a large evaluation battery that included the Spanish adaptation of the Personal Outcome Scale (POS). Likewise, fMRI sequences were obtained on a 3T resonator. For each subject, the DMN functional connectivity network was studied by estimating the indicators of complexity networks. The variability obtained in the Down syndrome group was studied by taking into accoun...
