Objectives To determine to what degree the predominance of risky sexual behaviour during adolescence is the result of social influence, in particular that of peers, according to the perception of their attitudes and sexual behaviour. Methods Data were collected through structured and confidential individual interviews with 100 adolescents, selected randomly from among 1467 students attending one French high school. Results Although this study is of an exploratory nature, it reveals that the perception of peers is associated with a higher frequency of sexual initiation and commitment, including oral sex, but also commitment to protected sex. Sexual permissiveness of peers is associated with a higher frequency of sexual practices considered risky. The attitudes of peers with regard to contraception are associated with protective contraceptive attitudes, without a direct influence on behavioural patterns. Conclusions The sexual norms of peers influence youths' individual attitudes and behaviours. Gender differences in sexual socialization also play a role. Both aspects must be taken into account when devising prevention programmes concerning adolescent sexuality.

Although there are many studies examining the psychosocial vulnerability factors of intimate partner violence (IPV) victimization in emerging adulthood, little is known about the life skills that may be involved, such as social problem solving (SPS) and self-esteem. The aim of the current study is to explore the relationships between SPS, self-esteem, and types (i.e., psychological, physical and sexual) and severity of IPV victimization in emerging adulthood. Based on a French online survey, 929 emerging adults (84.6% of whom were women with a mean age of 23.6) completed self-report questionnaires related to SPS (problem orientations and problem-solving styles), self-esteem and IPV victimization. The results showed that positive SPS skills and higher self-esteem were associated with lower severity of IPV. Multivariate analyses showed that the most associated factors of severe forms of IPV were avoidant and impulsive/carelessness styles. Minor sexual violence was positively associated with lower self-esteem and rational problem-solving skills, while minor psychological victimization was related to avoidant style. Upon completion of this study, it can be said that conflicts which escalate into IPV may be associated with dysfunctional conflict resolution styles, highlighting the importance of interventions that promote the development of life skills in order to prevent IPV.
