Despite the well documented mental health consequences of bullying behavior, bullying has not been studied in a mental health population. This study has examined psychosocial factors (symptoms of internalizing disorders and cognitive style) in a population of adolescents admitted into a partial hospitalization program. Sixty-four participants completed five self-report measures. This study was not able to differentiate among bully typologies based on internalizing symptoms (PTSD and depression) or self-debasing cognitive style. Instead, a more relevant finding was that more than half of the sample had clinical levels of PTSD and depressive symptoms. Because this sample was more similar than it was different, bully typologies were not relevant. It was proposed that trauma focused treatment strategies would better address the core issue of trauma.
