Longitudinal model of intake symptomatology, AA participation and outcome: Retrospective study of the project MATCH outpatient and aftercare samples.
The present study used data gathered in Project MATCH to longitudinally assess intake symptomatology, Alcoholics Anonymous (AA) participation, and outcome.
Three primary constructs were considered:
- intake symptomatology,
- engagement in prescribed AA-related activities, and
- functioning after engagement in AA-related behaviors.
The participants were 480 outpatient and 434 aftercare clients who participated in Project MATCH.
Similar findings were found for each sample.
Intake symptomatology positively predicted AA participation during the first 6 months following treatment.
AA participation positively predicted frequency of abstinent days in Months 7-12 posttreatment.
AA participation was positively related to self-efficacy to avoid drinking, which, in turn, predicted more days abstinent.
One difference between the outpatient and aftercare samples emerged, involving the latent construct intake symptomatology. Intake symptomatology among outpatients was not predictive of percentage of abstinent days (Months 7-12), whereas intake symptomatology was negatively predictive of percentage of abstinent days in the aftercare sample.
Intake symptomatology positively predicted participation in AA, which predicted subsequent abstinent days.
