Abstract
This study examined concurrent and longitudinal associations among peer victimization, peer status, and self-injurious thoughts and behaviors (i.e., suicidal ideation and nonsuicidal self-injury [NSSI]) over a 2-year period. A community sample of 493 adolescents (51% girls) in Grades 6-8 participated in the study. Participants completed measures of suicidal ideation and NSSI at three time points. Measures of peer victimization (overt and relational) and peer status (preference-based and reputation-based popularity) were collected by using a standard sociometric procedure. The hypothesized model was examined by using a multiple group (by gender) latent growth curve analysis. Results suggested that high levels of overt victimization were associated with increases in suicidal ideation over time for girls. No effects were revealed for relational victimization in the prediction of concurrent or longitudinal associations with suicidal ideation for boys or girls. With respect to peer status, low levels of preference-based popularity were associated with increases in suicidal ideation over time. Implications for understanding the complex patterns of association among different forms of peer victimization, self-injurious thoughts and behaviors, and peer group status are discussed.
