Drug addiction; Anxiety; Substance abuse


Substance abuse is a significant problem that often begins during adolescence. Many areas of an individual’s life may be affected, including physical and mental health, educational or occupational status, personal relationships, finances, and legal issues. Current treatment options for substance abuse exist, but are complicated and have limitations. Anxiety and psychopathy are important psychological characteristics to understand in examining substance abuse, particularly for criminal offender populations. In this study, adult male prison inmates will be classified based on trait anxiety (assessed with the Welsh Anxiety Scale) and psychopathy (assessed with the Psychopathy Checklist-Revised). The study’s hypotheses are that (1) psychopathic prison inmates will have greater substance abuse problems (as measured with the SCID and MAST-AD) than non-psychopathic prison inmates, and (2) psychopathic prison inmates with high anxiety will have greater substance abuse problems than psychopathic inmates with low anxiety.
