Adolescents' and their friends' sexual behavior and intention: Selection effects of personality dimensions

Using simulation investigation for empirical network analyses (in RSiena) we examined how personality and sexual behavior and intention were related to peer processes in Dutch adolescents. Our main research questions were: (a) do adolescents cluster together in friendship networks based on personality, sexual behavior, and/or sexual intention? And (b), do adolescents influence each other in their sexual behavior and intention? Results showed that adolescents clustered together based on dissimilarity in agreeableness, and similarity in gender and sexual intention. Further, we found that adolescents with lower levels of emotional stability had friends with more similar levels of sexual intention. The limited variance and low base rates of sexual behavior and intention did not allow us to explicitly test socialization effects.
