The present study was designed to investigate the relationship between psychological adjustment (i.e., anxiety, depression, and mania), personality disorder features (i.e., antisocial and borderline personality disorders), and treatment outcomes, while controlling for demographic variables (i.e., age and criminal history) for individuals participating in the Forrest/Perry Drug Court Program in South Mississippi. More specifically, treatment outcomes in this study were measured by the percentage of positive urine drug screens, percentage of missed drug court hearings, and completion versus non-completion during the participant's first 90 days of the program. Four hierarchical linear regression analyses and two hierarchical discriminant function analyses were used to explore the relationship. Findings indicated that personality variables (i.e., PAI Antisocial and Borderline scale scores) accounted for a significant portion of variance in the percentage of positive drug screens beyond that accounted for by participants' age, criminal history, and scores on the PAI Depression, Mania, and Anxiety scales. Psychological adjustment (i.e., PAI Anxiety, Depression and Mania scale scores) were not significant in predicting percentage of positive urine drug screens, percentage of missed drug court hearings or completion status during the participants' first 90 days of the program.
