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.
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.
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.
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.
研究人员已经开发出几种工具来衡量恢复资本——帮助人们解决酒精和其他药物问题的社会、身体、人力和文化资源。然而，现有的衡量标准受到理论和心理计量学弱点的限制。本研究报告了一种新的恢复资本衡量工具——多维恢复资本量表（MIRC）的编制过程和心理计量学结果。
我们使用了一个三阶段的混合方法来开发 MIRC。每个阶段都招募了那些被认为已经解决了酒精问题的个体。第一阶段专注于项目开发，参与者对潜在项目提供了定性反馈。在第二阶段（试点测试）和第三阶段（最终心理计量评估）中，参与者完成了 MIRC 的修订版本，以评估其心理计量学强度和项目表现。
第一阶段（n=44）导致了显著的项目改变，最终形成了一个 48 项的试点量表。试点测试分析（n=497）导致 17 个项目被删除或替换。在最终的心理计量评估（n=482）中，又删除了另外 4 个项目，形成了一个包含社会、身体、人力和文化资本四个分量表的 28 项 MIRC。最终 MIRC 及其分量表的心理计量学特性从良好到强不等，高反应变异性表明适当的项目区分度。
结果证实了 MIRC 的心理计量学强度，并强调了在恢复过程中纳入不同样本的见解的重要性。MIRC 有望成为未来研究中的一种评估工具，并且可以在治疗和社区环境中免费使用。
