We applied standardised clinical questionnaires in a semi-structured interview for the assessment of exposure to traumatic stress (Children Exposed to Community Violence (CEVC)), trauma symptomatology (PSS-I for diagnosis of post-traumatic stress disorder), aggression (Appetitive Aggression Scale (AAS); Buss & Perry Aggression Questionnaire), offense types checklist (from the AAS) and related drug abuse, psychosocial functioning (Work and Social Adjustment Scale, WSAS) and suicidality (M.I.N.I. 6.0.0., shortened version). Additionally, we used a questionnaire about social acknowledgement (Social Acknowledgement Questionnaire) and substance dependence (M.I.N.I. version 6.0.0).
