The present study examined the relations between personal values, value congruence, interpersonal relationships and subjective well‐being in psychology/education and business students from Argentina (N = 275), Bulgaria (N = 182) and Finland (N = 148). Regression analyses showed, first, that there were no direct relations between higher order value priorities and life satisfaction (LS), positive affect (PA) or negative affect (NA). Second, objective value‐congruence (VC)—the similarity between individual and group values—was positively related to LS and PA, and negatively related to NA. Most importantly, the effects of VC on LS, NA and PA were partially mediated by good interpersonal relationships. Our results show that interpersonal relationships are facilitated by sharing values similar to those of one's fellow students. More generally, personal values per se appear not to be associated with subjective well‐being, more important is how these values fit into the social context.

This research explored the relative contributions of subjective perceptions of body weight and body shape/proportion, as well as objective measures of body mass index (BMI) and waist-to-hip ratio (WHR) to disordered eating, exercise involvement, and body image. One hundred and fifty-eight female university students completed questionnaires and provided body measurements for this study. Although an interaction between BMI and WHR was found for some measures (i.e., Eating Disorder Examination Questionnaire total and subscale scores), results indicated that BMI was consistently the better objective predictor of disordered eating and body image. Subjective perceptions of body weight and, to a lesser extent, body shape, were found to account for the greatest proportion of variance in the dependent measures (disordered eating, body esteem, and body dissatisfaction). Overall, these results offer more support for sociocultural theories emphasizing the importance of thinness for women, than evolutionary theories emphasizing the role of WHR.  相似文献

One of the main objectives of many empirical studies in the social and behavioral sciences is to assess the causal effect of a treatment or intervention on the occurrence of a certain event. The randomized controlled trial is generally considered the gold standard to evaluate such causal effects. However, for ethical or practical reasons, social scientists are often bound to the use of nonexperimental, observational designs. When the treatment and control group are different with regard to variables that are related to the outcome, this may induce the problem of confounding. A variety of statistical techniques, such as regression, matching, and subclassification, is now available and routinely used to adjust for confounding due to measured variables. However, these techniques are not appropriate for dealing with time-varying confounding, which arises in situations where the treatment or intervention can be received at multiple timepoints. In this article, we explain the use of marginal structural models and inverse probability weighting to control for time-varying confounding in observational studies. We illustrate the approach with an empirical example of grade retention effects on mathematics development throughout primary school.  相似文献

In Dutch criminal cases in which doubts arise about the defendant's mental health, a forensic assessment will be requested. This is provided either by the multidisciplinary staff of residential clinics who conduct forensic evaluations for the court, or by mental health professionals contracted on a part-time basis by district courts. This article discusses the procedures applied in such cases as well as the relevant legal provisions. It focuses particularly on the clinical observation, evaluation, and reporting that is carried out over a number of weeks in the residential setting of the Pieter Baan Centrum. Specific attention is paid to procedures applied in this clinic. It is suggested that Dutch procedures for the use of mental health expertise can best be characterized by three aspects: multidisciplinary observation and reporting, the use of a sliding scale for indicating degree of responsibility, and, finally, the involvement and payment of experts by the state as such, rather than by the prosecution and/or the defense.

This study examined children's spontaneous use of behavioral emotion regulation (ER) strategies and their effects on subsequent mood change in response to an in vivo peer rejection manipulation. Participants (N = 186), ranging between 10 and 13 years of age, played a computer game based on the television show Survivor and were randomized to either peer rejection (being voted out of the game) or nonrejection control. In response to rejection, more than one third of the participants (38%) displayed a marked worsening (i.e., reliable change) in state mood. After receiving feedback, time spent on several behavioral ER strategies during a 5-minute postfeedback period was assessed. At the end of the postfeedback period, children's cognitive activity was also assessed. More time spent on behavioral distraction was positively linked to subsequent increases in positive affect, whereas the reverse pattern was found for disengagement/passive behavior. Moreover, higher endorsement ratings for the strategy of "cognitive analysis" were associated with stronger increases in negative affect.  相似文献
