Tornadoes and other natural disasters can lead to anxiety and posttraumatic stress disorder (PTSD) in children. This study provides further validity for the Oklahoma State University Post-Traumatic Stress Disorder Scale-Child Form (OSU PTSDS-CF) by comparing it to the Behavior Assessment System for Children Self-Report of Personality (BASC-SRP). Correlations were significant at 0.01 between BASC-SRP scales of Anxiety, Atypicality, and Clinical Maladjustment, and at least 0.05 between OSU PTSDS-CF scales for Social Stress, Depression, Inadequacy, and Emotional Symptoms Index (ESI). Analyses of variance (ANOVAs) yielded significant differences at 0.01 between children with and without PTSD, based on OSU PTSDS-CF cut-off scores, for BASC-SRP Anxiety, Atypicality, and Clinical Maladjustment. ANOVAs were significant at 0.05 for Social Stress, Locus of Control, Relationship with Parents, and ESI. Results yielded moderate effect sizes, and BASC-SRP means were within normal limits for all groups. Practitioners are encouraged to supplement the BASC-SRP with PTSD measures in children who have experienced trauma. (Contains 3 tables.)
