The Occupational Self-Assessment, Version 2.2 (OSA 2.2), is a client-centered measure of clients' perceived occupational competence and value. The OSA 2.2 has previously demonstrated good structural validity and internal consistency; however, the administration length could deter therapists from using this assessment in acute care and acute inpatient rehabilitation.
To evaluate reliability and validity of the OSA 2.2 in acute care and acute inpatient rehabilitation and to develop and validate the OSA-Short Form (OSA-SF).
We performed a descriptive psychometric analysis using the Rasch analytic approach.
The data were collected in acute care and acute inpatient rehabilitation.
Our convenience sample consisted of 86 patients in acute care and acute inpatient rehabilitation.
Participants rated their perceived occupational competence and value by completing the OSA 2.2.
We examined psychometric properties of the OSA 2.2 and OSA-SF using a partial credit Rasch model. The 21-item OSA 2.2 was reduced to a 12-item OSA-SF through iterative removal of items on the basis of item-misfit statistics. The OSA-SF demonstrated adequate rating scale functioning, dimensionality, item and person goodness of fit, item targeting, item hierarchies, and item and person separation.
Findings indicate that the OSA-SF is a valid and reliable measure that can guide client-centered goal setting and intervention planning for adults receiving acute care and acute inpatient rehabilitation.
The OSA 2.2 and the OSA-SF offer a client-centered approach to evaluating patients' self-reported ability and ratings of the importance of performing everyday occupations. These assessments can guide client-centered goal setting in acute care and acute inpatient rehabilitation.
职业自我评估2.2版（OSA 2.2）是以客户为中心的对客户感知到的职业能力和价值的一种测量方法。OSA 2.2先前已证明具有良好的结构效度和内部一致性；然而，其施测时长可能会阻碍治疗师在急性护理和急性住院康复中使用该评估工具。
评估OSA 2.2在急性护理和急性住院康复中的信度和效度，并开发和验证OSA简表（OSA-SF）。
我们采用拉施分析方法进行了描述性心理测量分析。
数据收集于急性护理和急性住院康复环境中。
我们的便利样本包括86名急性护理和急性住院康复患者。
参与者通过完成OSA 2.2来对他们感知到的职业能力和价值进行评分。
我们使用部分计分拉施模型检验了OSA 2.2和OSA-SF的心理测量特性。通过基于项目拟合统计数据迭代删除项目，将21项的OSA 2.2缩减为12项的OSA-SF。OSA-SF表现出足够的量表功能、维度性、项目和人员拟合优度、项目靶向性、项目层次结构以及项目和人员区分度。
研究结果表明，OSA-SF是一种有效且可靠的测量工具，可指导接受急性护理和急性住院康复的成年人以客户为中心的目标设定和干预计划。
OSA 2.2和OSA-SF提供了一种以客户为中心的方法来评估患者自我报告的能力以及对进行日常职业重要性的评分。这些评估可指导急性护理和急性住院康复中以客户为中心的目标设定。
