Longitudinal trajectories in recovery capital and associations with substance use among adult drug treatment court clients.

BACKGROUND: Recovery capital (RC) refers to the resources individuals use to support substance use disorder (SUD) recovery. Individuals with SUD who are involved with the criminal justice system often have limited RC. Drug treatment courts (DTCs), including traditional drug treatment courts (tDTCs) and opioid intervention courts (OICs), can link clients to important sources of RC in the short-term, but few studies have assessed RC longitudinally. METHODS: The current study analyzed five waves of data from a one-year longitudinal study on substance use and RC collected from clients of tDTCs and OICs (n=165, 52% male, 75% non-Hispanic White, Age=21-67 years). Mixed-effects models examined (1) within-person trends over time in RC, (2) individual characteristics associated with differences and changes in RC, and (3) patterns of relationships between RC and substance use over time. We also tested differences by court type. RESULTS: First, OIC participants had lower RC at baseline relative to tDTC participants, and there was considerable within-person variability in RC over time. Second, the effect of a high school diploma/GED at baseline on RC change over time was greater for OIC relative to tDTC participants. Third, there was a negative concurrent within-person association between drug use and RC that became stronger over time for OIC relative to tDTC participants. CONCLUSIONS: This study is among the first to examine longitudinal, within-person trajectories in RC. Results revealed important within-person variability over time in RC that was linked to education and drug use, particularly among OIC clients. Findings could help inform DTC treatment approaches.

Development and psychometric properties of the Multidimensional Inventory of Recovery Capital (MIRC).

BACKGROUND: Researchers have developed several instruments to measure recovery capital-the social, physical, human, and cultural resources that help people resolve alcohol and other drug problems. However, existing measures are hampered by theoretical and psychometric weaknesses. The current study reports on process and psychometric outcomes for the Multidimensional Inventory of Recovery Capital (MIRC), a novel measure of recovery capital. METHODS: We used a three-phase, mixed methods approach to develop the MIRC. Individuals who identified as having resolved alcohol problems were recruited in each phase. Phase one focused on item development, with participants providing qualitative feedback on potential items. In phase two (pilot testing) and phase three (final psychometric evaluation), participants completed revised versions of the MIRC to assess its psychometric strength and item performance. RESULTS: Phase one (n=44) resulted in significant item alteration, culminating in a 48-item pilot measure. Pilot testing analyses (n=497) resulted in the deletion or replacement of 17 items. In the final psychometric evaluation (n=482), four additional items were deleted, resulting in a 28-item MIRC comprising four subscales measuring social, physical, human, and cultural capital. The psychometric properties of the final MIRC and its subscales ranged from sound to strong, with high response variability suggesting appropriate item discrimination. CONCLUSION: Results confirm the psychometric strength of the MIRC and underscore the importance of incorporating the insights of diverse samples of people in recovery. The MIRC holds promise as an assessment tool in future research and is available for use at no cost in treatment and community-based settings.

Qualitative insights in item development for a comprehensive and inclusive measure of recovery capital.

Background: Item specification is foundational to measurement development but rarely reported in depth. We address this gap by explicating our use of qualitative methods to ground and develop items for a new recovery capital measure, the Multidimensional Inventory of Recovery Capital. Method: We recruited a diverse sample of service providers (n = 9) and people in recovery from alcohol problems (n = 23) to provide feedback on an item pool assessing social, human, physical, community, and cultural capital. Using applied qualitative analysis, we coded findings from interviews and focus groups and made final decisions by consensus regarding item elimination, retention, or revision. This process yielded a 49-item draft measure. Results: Only nine items from an initial 90-item list were retained in their original form. Participant feedback guided item elimination, addition, and revision for linguistic or conceptual clarity. We detected little systematic variation in feedback based on income or race; however, there were stark divergences on particular items based on recovery pathway (i.e. 12-step versus other approaches). Conclusions: The high degree of alteration to the item pool highlights the importance of establishing validity with respondents. Response variation based on recovery pathway suggests the need for broad heterogeneity in respondents. Measures that are sensitive, psychometrically sound, and aligned with theory are critical for advancing research on recovery capital and related disparities for diverse populations.

Conceptualizing recovery capital: expansion of a theoretical construct.

In order to capture key personal and social resources individuals are able to access in their efforts to overcome substance misuse, we introduced the construct of recovery capital into the literature. The purpose of this paper is to further explore the construct and include discussions of implications unexplored in our previous writings. In this paper we reveal the relationship between access to large amounts of recovery capital and substance misuse maintenance and introduce the concept of negative recovery capital. In doing so, we examine the relationships between negative recovery capital and gender, age, health, mental health, and incarceration.
