背景：长期以来，人们已经确定，从酒精或其他药物使用障碍中恢复过来与增加的生物行为压力有关。为了增加恢复的机会，各种心理、身体、社会和环境资源被认为是重要的，因为它们可以帮助减轻这种高压力负担。制定了50个项目的恢复资本衡量标准(恢复资本评估[ARC])，有10个子量表；然而，一个更简短的版本可以加强在研究和繁忙的临床/恢复支持服务环境中的进一步部署。为了帮助提高测量的实用性，本研究的目标是使用项目反应理论模型创建一个较短的版本。方法：从来自苏格兰和澳大利亚(N=450)的原始处理样本中汇集项目以进行规模缩减。在独立样本(N=123)中测试了简化版本，并构建了接收器操作特征曲线以确定持续缓解的最佳截止(>；结果：简明的10个条目的康复资本量表(BARC-10)从所有10个原始分量表中获取条目表征，在参与者的地区和性别之间保持不变，具有较高的内部一致性(α=.90)，与原始测量的同时效度(r(PB)=.90)，以及持续缓解的预测效度(r(PB)=.90)。结论：《康复资本10条目版本简明评估》(BARC-10)简明地测量了恢复资本的单一统一维度，可能对研究者、临床医生和康复支持服务具有实用价值。
Background: It has been long established that achieving recovery from an alcohol or other drug use disorder is associated with increased biobehavioral stress. To enhance the chances of recovery, a variety of psychological, physical, social, and environmental resources, known as "recovery capital", are deemed important as they can help mitigate this high stress burden. A 50-item measure of recovery capital was developed (Assessment of Recovery Capital [ARC]), with 10 subscales; however, a briefer version could enhance further deployment in research and busy clinical/recovery support service settings. To help increase utility of the measure, the goal of the current study was to create a shorter version using Item Response Theory models.Method: Items were pooled from the original treatment samples from Scotland and Australia (N = 450) for scale reduction. A reduced version was tested in an independent sample (N = 123), and a Receiver Operating Characteristic Curve was constructed to determine optimal cut-off for sustained remission (>12 months abstinence).Results: An abbreviated 10-item measure of recovery capital captured item representation from all 10 original subscales, was invariant across participant's locality and gender, had high internal consistency (alpha = .90), concurrent validity with the original measure (r(pb) = .90), and predictive validity with sustained remission using a cut-off score of 47.Conclusion: The brief assessment of recovery capital 10-item version (BARC-10) concisely measures a single unified dimension of recovery capital that may have utility for researchers, clinicians, and recovery support services.
