Following a threat of violence, the PETRA enables you to analyze the context of psychosocial, ecological, and coping/resiliency factors to assist in the identification, assessment, intervention and treatment planning, and behavioral management of adolescents who pose a risk of targeted violence toward others.

  • Designed for use with adolescents who exhibit threatening behavior, primarily in school. Critical items identify known threat risk factors.
  • The PETRA provides four domain scores (Psychosocial, Resiliency Problems, Ecological, Total), eight cluster scores (Depressed Mood, Alienation, Egocentricism, Aggression, Family/Home, School, Stress, Coping Problems), two response style indicators (Inconsistency, Social Desirability), and eight critical items.
  • Interpretation is straightforward and incorporates a thorough five-step systematic methodology for gathering, guiding, and interpreting multisource data. Results should be considered in light of background information, information from other informants, and information gathered from follow-up interviews.
