Personality Characteristics of Cocaine and Opiate Addicts who Participate in a 12-Step Program
by Klutcharch, Edward, Psy.D., The Chicago School of Professional Psychology, 2011, 96; 3463686
Abstract (Summary)

This dissertation study sought to compare the personality characteristics of cocaine addicts and opiate addicts and to assess the effects of 12-Step participation on personality characteristics using the Millon Clinical Mutiaxial Inventory III (MCMI-III).

All subjects were volunteers from the Chicago Region's South Suburban Area of Narcotics Anonymous (NA) of which 30 were male (68.2%) and 14 female (31.8%), 39 Caucasian, and 5 African American. Three groups of addicts based on drug of choice comprised the study: 20 cocaine addicts, 8 opiate addicts, and 16 with other or no drug of choice. Each subject was administered the MCMI-III and brief demographic questionnaire that included the 12-Step Participation Questionnaire.

Descriptive statistics and the correlational analysis between drug of choice and 12-Step participation and the personality scale scores were run to determine whether the assumptions of the ANOVA had been met. To determine whether the independent variables differed significantly upon the dependent variables, ANOVAs were used to compare the identified mean values of the independent variables. Further Analysis of Covariance (ANCOVA) tests were used to compare the effects of gender. A two-tailed alpha level of .05 served as the criterion for statistical significance.

There was a significant difference between Histrionic and Narcissistic Clinical Personality Patterns and the addicts' drug of choice. Histrionic scores for opioid addicts (M= 69.25) were significantly higher than cocaine addicts (M= 45.50) and Narcissistic scores for opioid addicts (M= 75.88) were significantly higher than cocaine addicts (M=49.70). There was not a significant difference between Antisocial Clinical Personality Patterns and the addicts Drug of Choice.

There was a significant difference between levels of 12-Step Participation and Antisocial Clinical Personality Patterns scores but not with the Narcissistic and Histrionic Personality Pattern scores, Antisocial Clinical Personality Pattern score for High 12-Step Participation group (M= 67.71) was significantly lower than Low 12-Step Participation group (M= 84.14), and lower, although not significantly lower, than the other groups.

The results of this study suggest that opioid addicts are more narcissistic and histrionic than cocaine addicts are and increased 12-Step participation is associated with fewer antisocial personality traits.
