The aim of this study was to investigate the link between suicidal ideation, psychological morbidity and experiences with peer violence (victim or perpetrator) among adolescents. This study examined direct and indirect violence separately. A sample of 361 high school students from France completed a self-administered survey consisting of the Suicidal Ideation Questionnaire, the Rosenberg Self-Esteem Scale and the General Health Questionnaire. Indirect peer victimization experienced by girls and direct peer victimization experienced by boys were more strongly linked to suicidal thoughts. Indirect aggression was also related to suicidal ideation among boys only. Indirect victimization at school was linked to a drop in self-esteem, a factor strongly related to the level of suicidal ideation, particularly for boys. These findings show that adolescent peer violence must be given particular attention in educational institutions due to its links not only with suicidal ideation, but also more broadly with students’ psychological distress.

We examined the psychometric qualities of the Short Form of the Coopersmith Self-Esteem Inventory (SF-CSEI) in a large sample of French adolescents and young adults. A 25-item French version was administered to 1,362 participants (561 aged below 16 years and 801 aged 16-25 years). Participants also completed other scales to measure construct validity (e.g., Rosenberg Self-Esteem Scale, Hospital Anxiety and Depression Scale, and General Health Questionnaire). Factorial analysis yielded evidence for a structure with three first-order factors for the SF-CSEI: personal, social, and family-derived self-esteem. The internal consistency of the questionnaire's different dimensions was satisfactory (Cronbach's α = .68-.77). Pearson's correlation coefficients showed that the SF-CSEI had moderate to high correlations with convergent measures (r = .19-.73) and constructs related to self-esteem (r = -.23-.65). Psychiatric patients (n = 67) scored significantly lower than a control group. Test-retest reliability was good for some of the factors, especially at 5 weeks and 1 year (r = .29-.79). The French version of the SF-CSEI appears to be a useful instrument, with a cross-culturally stable factorial structure.

La sexualité n’est pas réductible à une somme de comportements et de savoirs, la relation à l’autre joue un rôle décisif dans la détermination des pratiques sexuelles. Il s’agit d’aborder l’accession à la sexualité génitale comme découlant d’une unification des fonctions de sexualité et d’intimité. Un des buts de ces fonctions est d’accepter les enjeux de la différence et de la complémentarité avec soi. Dans ce cadre, la sexualité peut convoquer les formes les plus archaïques d’angoisses (incorporation, intrusion, dévoration par l’autre…). Instrumentalisation du courant sensuel ou idéalisation du courant tendre sont alors les principales difficultés psychoaffectives rencontrées.
