Abstract: This study's purpose was to develop a reliable and valid self-report questionnaire, the Child-Adolescent Suicidal Potential Index (CASPI), to screen for risk for suicidal behavior in children and adolescents. Four hundred twenty-five child and adolescent psychiatric patients and nonpatients completed the CASPI and other research instruments to rate suicidal and assaultive behavior and symptoms of depression, anxiety, and hopelessness. The 30-item CASPI involves 3 factors (anxious-impulsive depression, suicidal ideation or acts, family distress) that contributed to a unidimensional 2nd-order factor accounting for 59% of the total variance. Internal consistency (alpha) for the total score was .90, and test-retest reliability (ICC) for the total score was .76. Total score distinguished between children and adolescents with different severity of psychopathology and different levels of suicidal and assaultive behavior. Each of the 3 factors had different contributions to discriminating between levels of suicidal status. CASPI total score of 11 distinguished suicidal ideation or acts from nonsuicidal behavior, with sensitivity 70% and specificity 65%, CASPI total score positively correlated with symptom severity of depression, anxiety, and hopelessness.
