Personality and alcohol/substance-use disorder patient relapse and attendance at self-help group meetings.

This study evaluated the role of personality in the short-term outcome of alcohol/substance-use disorder patients. Detoxifying alcohol/substance-use disorder patients were administered the Myers-Briggs Type Indicator (MBTI), the Tridimensional Personality Questionnaire (TPQ), the Michigan Alcohol Screening Test (MAST), the CAGE Questionnaire, and the Beck Depression Inventory (BDI). These patients were subsequently evaluated over a 1-month period for relapse and attendance at self-help group meetings. High TPQ Persistence scale scores predicted abstinence. When the Thinking and Feeling groups were considered separately, and when these two groups were combined into a single group, high scores for the individual groups and the combined group (i.e. Thinking and Feeling types together) predicted abstinence. High TPQ Persistence scale scores and low Shyness with Strangers and Fear of Uncertainty subscale scores predicted attendance at self-help group meetings. High MBTI Extroversion and high MBTI Thinking scores also predicted attendance at self-help group meetings. When the Extroverted and Introverted types and the Thinking and Feeling types respectively were combined, as with abstinence, high scores predicted attendance at self-help group meetings. Age, gender, CAGE, MAST, and BDI scores did not predict outcome. The above information suggests that specific personality variables may predict abstinence and attendance at self-help group meetings in recently detoxified alcoholics, and this may have prognostic and therapeutic significance.
