Recovery capital is an individual’s total recovery resources based on their strengths. This study examines (1) the most important factor driving the growth of recovery capital among polydrug and non-polydrug drug users, (2) differences in recovery capital, (3) differences in the motivation process to stay sober, and (4) the relationship between recovery capital and treatment motivation. The data was collected randomly using predetermined respondent criteria. The Brief Assessment Recovery Capital-10 and Treatment Motivation Scale were completed by all respondents (n=270). To determine the relationship between Recovery Capital and Treatment Motivation in polydrug users and non-polydrug users, descriptive, T-test, and Pearson correlation analyses were performed. 62.22% of addicts used multiple substances, compared to 37.78% who used only one type of drug. 55 percent of respondents say substance use and sobriety are most important for recovery. “Housing & Safety” and “Risk-Taking Behavior” follow at 48.9%. Polydrug and non-polydrug groups had similar recovery capital (t (268) = 1.46, p = 0.144). Polydrug users had higher scores but lower overall scores. Polydrug and non-polydrug groups have significantly higher Treatment Motivation scores, t(268) = -2.222, p = 0.027. Even though non-polydrug users score higher. Polydrug users have a moderately positive correlation (r (268) = 0.400, p = 0.00), while non-polydrug users have a weak correlation (r (268) = 0.273, p = 0.00). Targeting recovery capital in treatment may improve resources and support networks, reducing relapse. Recovery capital assessments may help tailor multimodal services to an individual’s recovery needs while integrating harm reduction into addiction treatment.
