Weight status, psychological health, suicidal thoughts, and suicide attempts in Dutch adolescents: results from the 2003 E-MOVO project.

This study describes the association between weight status and psychological health, suicidal thoughts and suicide attempts in adolescents from a population-based study of 21,730 adolescents who responded to a classroom-based internet questionnaire. It demonstrated clear associations between weight status in adolescents and poor psychological health, suicidal thoughts and suicide attempts, especially in obese individuals. Obese boys and girls were more likely to be classified as "psychologically unhealthy" than were normal weight subjects. They also reported more suicidal thoughts and suicide attempts.

Bystanding an abused child: testing the applicability of the stages of change construct.

A minority of child abuse cases is recognized by professionals, making the role of non-professional bystanders essential. The stages of change construct, as proposed by the Transtheoretical Model, may provide a useful approach to explain non-professional helping behavior. The objective of this study was to test the applicability of the stages of change construct by (i) assessing whether cognitive determinants distinguish between the stages, (ii) testing the predictive value of the stages for future helping behavior and (iii) examining the mediating role of the stages in the relation between previous and future helping behavior. Data of 126 adult non-professional bystanders were analyzed. Respondents were questioned by telephone or via an Internet questionnaire, at baseline and after a follow-up of about two months later. Attitude toward helping was significantly less positive in pre-contemplation than in the other stages, and self-efficacy expectations were significantly higher in preparation compared with the other stages. Moreover, baseline preparators were more likely to conduct future helping behavior than those in the two earlier stages. Finally, the stages of change mediated the relation between previous and future helping behavior. Initial support was found for the applicability of the stages of change construct for helping behavior by non-professional bystanders.
