As the transition to adulthood becomes more protracted and less orderly, fewer young people occupy adult roles and experience the social control associated with these roles. One might therefore expect behaviors associated with the teenage years to spill over into older age groups, reflecting postponed entrance into full social adulthood. We test this hypothesis by examining trends over time in ...

This study integrates insights from evolutionary psychology and social epidemiology to present a novel approach to contextual effects on health-risk behaviors (unprotected sex, drunkenness episodes, drugs and tobacco experimentation) among adolescents. Using data from the 2012 Brazilian National Survey of Adolescent Health (PeNSE), we first analyzed the effects of self-reported violent victimiz...

Twenty-eight subjects with and 46 subjects without sleep-related violence (VBS) were evaluated regarding the presence of self-mutilative behaviors (SMBs). The subjects with and without VBS were compared using dissociative experiences scale (DES). The subjects with VBS had higher mean DES score and more frequent SMBs than those without VBS. These findings suggest that dissociation may be related...

Drawing from past research on women's motives for intimate partner violence (IPV) perpetration, correlates of women's perpetration, and correlates of nonviolent conflict, we created a scale containing 125 possible motives, representing 14 broad domains (e.g., self-defense, retaliation). Participants were an ethnically diverse sample of women who had perpetrated no physical IPV against their cur...

OBJECTIVE Men are more violent than women in the general population, but this has not been found to be the case among psychiatric inpatients. The reason for this exception is poorly understood. The present study investigated gender differences in violent behaviors among patients with major psychiatric disorders. It examined various clinical symptoms and psychosocial factors to determine their d...

This paper estimates the longer-term effects of childhood conduct disorder on human capital accumulation and violent and criminal behavior later in life using data of Australian twins. We measure conduct disorder with a rich set of indicators based on diagnostic criteria from psychiatry. Using ordinary least squares and twin fixed effects estimation approaches, we find that early-age (pre-18) c...

Surveys of self-reported behaviors of adolescents and young adults indicate high rates of offending among these age groups (Elliott et al., 1983; Lauritsen, Sampson, and Laub, 1991). Similarly, surveys of victims’ perceptions of offender characteristics indicate that the most common age group for offenders committing rape, robbery, and assault is youth ages 18–20, followed by juveniles ages 15–...

Violence in adolescence has seen an increase since the 1990s with dramatic statistics on violent death and risk behaviors. School violence has been focused upon by a huge media coverage of especially violent cases that could have had some endemic consequences worldwide. We present a case of a 14 year old white male with change in school behavior, strategies for the case investigation, its resul...
