The purpose of this study was to investigate the psychometric properties (i.e., reliability and validity) of a battery of scales and subscales used to measure Robert Johnson's mature coping construct. The battery of instruments includes a Program Attitudes Scale, a Coping Strategies Inventory, a Social Problem Solving Inventory, a Self-Esteem Inventory, a Depression Scale, and an Anti-Social Attitudes Scale. Statistical results demonstrating the factorial validity, internal consistency reliability, and the construct validity of each scale are presented. Furthermore, descriptive statistics for these scales are reported for the adult and juvenile boot camp samples at focus in this study.
