Development and initial validation of a 12-step participation expectancies questionnaire.

Objective: There are no available instruments that assess expectancies for participation in 12-step mutual-help groups despite the impact such expectancies may have on actual participation. The purpose of the present study was to develop a measure of attitudes and expectancies regarding 12-step participation, to conduct preliminary analyses on its psychometric properties, and to explore its concurrent and predictive validity.

Method: Alcohol-dependent patients (N=48) undergoing inpatient detoxification completed a questionnaire that included subscales assessing expected benefits of, concerns about, and barriers to 12-step participation. Participants also completed measures of 12-step group participation and drinking outcomes at 1, 3, and 6 months following discharge.

Results: After examining the internal consistency of the items within each subscale and refining the questionnaire accordingly, an exploratory factor analysis showed that the scales could be combined into a higher-order total score. This total score correlated significantly with prior 12-step experience and goals for attending future 12-step meetings. In addition, the Expectancies Total Score at baseline significantly predicted 12-step group participation during follow-up.

Conclusions: The measure of attitudes and expectancies regarding 12-step group participation demonstrated good internal consistency, concurrent validity, and predictive validity. The measure may have clinical utility in highlighting patients' expectancies regarding 12-step participation, allowing treatment providers to explore with patients the benefits, concerns, and barriers to involvement that they have endorsed.
