The current study was characterized by a number of limitations. These include the modest sample size (reducing the statistical power to detect associations), the fact that many of the covariates of interest had a very low prevalence, and the relatively brief follow-up interval. Although the analytic sample comprised individuals of diverse ages and varying lengths of dependence at baseline, the sample size did not permit examining potentially informative interactions of length of dependence or age cohort with the other correlates of recovery. Additionally, our measures of help-seeking may have included very brief encounters with the treatment and 12-step systems, as frequency of participation was not ascertained.
