The individual recovery outcomes counter is a 12-item personal recovery self-assessment tool for adults with mental health problems. Although widely used across Scotland, limited research into its psychometric properties has been conducted. We tested its' measurement properties to ascertain the suitability of the tool for continued use in its' present form.
Anonymised data from the assessments of 1743 adults using mental health services in Scotland were subject to tests based on principles of Rasch measurement theory, principal components analysis and confirmatory factor analysis.
Rasch analysis revealed that the six-point response structure of the individual recovery outcomes counter (I.ROC) was problematic. Re-scoring on a four-point scale revealed well-ordered items that measure a single, recovery-related construct, and has acceptable fit statistics. Confirmatory factor analysis supported this. Scale items covered around 75% of the recovery continuum; those individuals least far along the continuum were least well addressed.
A modified tool worked well for many, but not all, service users. The study suggests specific developments are required if the I.ROC is to maximise its' utility for service users and provide meaningful data for service providers. Implications for Rehabilitation Agencies and services working with people with mental health problems aim to help them with their recovery. The individual recovery outcomes counter has been developed and is used widely in Scotland to help service users track their progress to recovery. Using a large sample of routinely collected data we have demonstrated that a number of modifications are needed if the tool is to adequately measure recovery. This will involve consideration of the scoring system, item content and inclusion, and theoretical basis of the tool.
个体康复结果计数器是一种针对有心理健康问题的成年人的12项个人康复自我评估工具。尽管在苏格兰广泛使用，但对其心理测量特性的研究有限。我们测试了其测量特性，以确定该工具以其当前形式继续使用的适用性。
对苏格兰1743名使用心理健康服务的成年人的评估数据进行匿名处理，基于拉施测量理论、主成分分析和验证性因素分析的原则进行测试。
拉施分析表明，个体康复结果计数器（I.ROC）的六点反应结构存在问题。重新按四点量表评分显示，项目排列有序，测量单一的、与康复相关的结构，且具有可接受的拟合统计量。验证性因素分析支持这一点。量表项目涵盖了约75%的康复连续体；在连续体上进展最小的个体得到的关注最少。
一种经过修改的工具对许多（但不是所有）服务使用者都有效。该研究表明，如果I.ROC要最大限度地发挥其对服务使用者的效用并为服务提供者提供有意义的数据，就需要进行具体改进。对康复机构和为有心理健康问题的人提供服务的机构的启示旨在帮助他们康复。个体康复结果计数器已开发出来并在苏格兰广泛使用，以帮助服务使用者跟踪他们的康复进展。通过使用大量常规收集的数据样本，我们证明如果该工具要充分测量康复情况，需要进行一些修改。这将涉及对评分系统、项目内容和纳入情况以及工具的理论基础的考虑。
