Firearm injury is a significant public health concern among youth living in the United States. Youth with exposure to violence (ETV) are more susceptible to carrying and using a firearm. Few researchers, however, have examined psychological mechanisms undergirding the association between ETV and firearm aggression. Retaliatory attitudes have been…

Evidence suggests that the consequences of chronic exposure to stressors extend beyond psychological effects, and that adolescents living in socio-economically disadvantaged neighborhoods may experience an accumulation of exposure to stressors that wears down the physical systems in the body, resulting in hyper-activation of the stress response.…

This study examined the effects of cumulative risk and promotive factors on violent behavior across the high school years of adolescence in a sample of predominately African American urban adolescents (N = 750). Cumulative risk and promotive factor indices represented individual characteristics, and peer, parental, and familial influences. Using…

The study investigated how role models' behavior may positively or negatively influence African American early adolescents' attitudes toward violence and violent behavior. Participants in this study included 331 African American seventh and eighth graders from low-income neighborhoods in an urban, Midwestern city. The study used a model developed…

We study household composition change and its effect on development, as measured by both internalizing symptoms and externalizing behaviors, in a sample of urban African American adolescents. Household change was defined based on the movement in or out of the…

This study explored how neighborhood characteristics may relate to African American adolescents' internalizing symptoms via adolescents' social support and perceptions of neighborhood cohesion. Participants included 571 urban, African American adolescents (52% female; "M" age = 17.8). A multilevel path analysis testing both direct and…

We investigated whether role models (individuals adolescents look up to) contributed to the resilience of adolescents who were exposed to negative nonparental adult influences. Our sample included 659 African American, ninth-grade adolescents. We found that adolescents' exposure to negative adult behavior was associated with increased…

The association between marijuana use and depressive symptoms was examined longitudinally in a sample of 622 African American youth, interviewed on six occasions, using hierarchical linear modeling (HLM). We considered whether depressive symptoms predicted changes in marijuana use and vice versa from high school through the transition into young…

Investigated gender-specific contextual and individual socioeconomic predictors of the timing of first intercourse among low-achieving African American high school students, following financial deprivation and collective socialization theories. Data from 3 years of surveys indicated that males and females were affected differently by social…

Examined relationship of role models among African American ninth-graders to substance use, delinquency, academic engagement, and psychological well-being. Found that males without male role models and females identifying brothers as role models reported the most problem behavior. Adolescents with paternal role models had most positive school…
