Adolescence is a period of dramatic change that necessitates using skills and strengths to reduce physical aggression and increase happiness. This study examined the multiple facets of self-control skills in achieving both goals simultaneously, in a sample of 248 Arab adolescents in Israel. We conceptualized and tested a new multi-mediator model that posited two parallel paths. Structural equation modeling with bootstrap analysis supported the hypothesized model where self-control linked with subjective happiness directly, and indirectly through positive emotions and social support. In addition, self-control linked directly to physical aggression, and indirectly through hostility and anger. The findings provide new theoretical conceptualizations for further research and suggest possible mechanisms for prevention and intervention programs.
