The influence of parent's body mass index on peer selection: An experimental approach using virtual reality

Relatively little is known about the influence of psychosocial factors, such as familial role modeling and social network on the development and maintenance of childhood obesity. We investigated peer se- lection using an immersive virtual reality environment. In a virtual schoolyard, children were confronted with normal weight and overweight avatars either eating or playing. Fifty-seven children aged 7–13 participated. Interpersonal distance to the avatars, child's BMI, self-perception, eating behavior and parental BMI were assessed. Parental BMI was the strongest predictor for the children's minimal distance to the avatars. Specifically, a higher mothers' BMI was associated with greater interpersonal distance and children approached closer to overweight eating avatars. A higher father's BMI was associated with a lower interpersonal distance to the avatars. These children approached normal weight playing and overweight eating avatar peers closest. The importance of parental BMI for the child's social approach/ avoidance behavior can be explained through social modeling mechanisms. Differential effects of pa- ternal and maternal BMI might be due to gender specific beauty ideals. Interventions to promote social interaction with peer groups could foster weight stabilization or weight loss in children.

Selbstbereicherung an kollektiven Ressourcen. «Eigennutz» als Leitmotiv politischer und sozialer Skandalisierung in der vormodernen Eidgenossenschaft

Angemessen historisiert kann der «Skandal» auch für die Vormoderne als produktive Forschungskategorie genutzt werden, um nach fundamentalen Wertehaltungen und zugehörigen Konfliktmodi zu fragen. Während Skandale in heutiger Zeit über massenmedial verbreitete Enthüllungen befeuert werden, adressierte Skandalisierung in der Vormoderne unterschiedliche Kommunikationsräume wie etwa Familie, Peer Groups, politische Gremien und Versammlungen, die als ständisch gerahmte, ineinander verschachtelte und miteinander interagierende Teilöffentlichkeiten fungierten. Eigentliches Skandalon stellte der Vorwurf des Eigennutzes bzw. die Schädigung des gemeinen Nutzens dar. Angeprangert wurden Selbstbereicherung, undurchsichtige Machenschaften oder übermässige Profite aus Amtstätigkeiten. Skandalen kam dabei die Funktion von Läuterungsritualen zu, welche lokalen Gesellschaften und ständischen Gruppen die ungeschriebenen Gesetze ihres Zusammenlebens in Erinnerung riefen.

Who benefits from peer support in psychiatric institutions?

This study examines the influence of recovery-oriented peer events on participants' recovery attitudes and explores who benefits most from such events. Changes in participants' recovery attitudes were evaluated (pre, post, follow-up), and compared with changes of control groups. Distributions of recovery-related values in subgroups were analyzed descriptively. The results of non-parametric tests (Friedman) showed participants with significantly higher values in the dimension Recovery is possible directly after the interventions (P = 0.006), but not 6 months later, and not in comparison with members of control groups. On a descriptive level, women, participants with schizophrenia and with two or more episodes of the disorder showed higher recovery-related values compared to men, participants with an affective disorder and only one episode. Within their feedback, organizations and peers express a positive view of peer support, but evidence for a positive impact of the evaluated peer events on recovery attitude is limited.

Cost-effectiveness of peer role play and standardized patients in undergraduate communication training.

BACKGROUND The few studies directly comparing the methodological approach of peer role play (RP) and standardized patients (SP) for the delivery of communication skills all suggest that both methods are effective. In this study we calculated the costs of both methods (given comparable outcomes) and are the first to generate a differential cost-effectiveness analysis of both methods. METHODS Medical students in their prefinal year were randomly assigned to one of two groups receiving communication training in Pediatrics either with RP (N = 34) or 19 individually trained SP (N = 35). In an OSCE with standardized patients using the Calgary-Cambridge Referenced Observation Guide both groups achieved comparable high scores (results published). In this study, corresponding costs were assessed as man-hours resulting from hours of work of SP and tutors. A cost-effectiveness analysis was performed. RESULTS Cost-effectiveness analysis revealed a major advantage for RP as compared to SP (112 vs. 172 man hours; cost effectiveness ratio .74 vs. .45) at comparable performance levels after training with both methods. CONCLUSIONS While both peer role play and training with standardized patients have their value in medical curricula, RP has a major advantage in terms of cost-effectiveness. This could be taken into account in future decisions.
