Individual and contextual predictors of involvement in twelve-step self-help groups after substance abuse treatment.
Drawing on ecological and narrative theories of self-help groups, this study tests a multilevel model predicting self-help group involvement among male veterans who received inpatient substance abuse treatment. Following K. Maton (1993), the study moves beyond the individual-level of analysis to encompass variables in the treatment and post-treatment social ecology. Surveys administered to patients (N = 3,018) and treatment staff (N = 329) assessed these predictor domains and self-help group involvement 1 year after discharge. A hierarchical linear model fit to the data indicates that greater involvement in 12-step groups after discharge is predicted by the compatibility between personal and treatment belief systems. The implications of these findings for efforts to facilitate transitions between inpatient professional treatment and community-based self-help groups are discussed.
