We evaluates the gender matching hypothesis in Project MATCH, which states that women will benefit more from Cognitive-Behavioral Coping Skills Therapy (CBT) than from Twelve Step Facilitation (TSF).

CBT was expected to address the ancillary problems (e.g., external stressors, negative mood) that are more prevalent among female alcoholics; at the same time, TSF, which would encourage women to attend Alcoholics Anonymous (AA) meetings, was expected to increase guilt and undermine self-esteem and assertion.

Tests of the matching contrasts failed to provide support for the hypothesis in either arm of the trial.

Gender did produce significant prognostic effects in analyses of the aftercare arm, with women reporting a higher proportion of abstinent days and fewer drinks per occasion than men did.

Causal chain analyses produced mixed results. Male and female clients were shown to differ in terms of their initial treatment needs, and follow-up status with respect to these needs was related to drinking outcomes.

Contrary to prediction, however, CBT sessions for women, as compared to those for men, were not appreciably more likely to teach general problem-solving or mood-management skills.

Further, women did not avoid AA meetings.

  • Attendance at self-help meetings was comparable for the sexes in the outpatient arm;
  • in the aftercare study, women attended significantly more meetings and reported a higher degree of AA involvement.
