: In occupational science and therapy, occupations are understood as meaningful activities. Satisfaction with the amount and variety of occupations is called occupational balance. The "Occupational Balance in Informal Caregivers" (OBI-Care) questionnaire assesses satisfaction with occupations across three subscales: occupational areas, characteristics, and resilience. In doing so, it also addresses occupational contingency, i.e., the ability to adapt occupations in response to unforeseen events. While previous studies have confirmed its validity in other populations, psychometric properties have not been explored in informal caregivers of stroke survivors. This study aimed to evaluate the construct validity, internal consistency, and suitability of the German OBI-Care for assessing occupational balance for this target group. A validation study was conducted using data collected via an online survey. Measurement properties of the three subscales were examined using Rasch Rating Scale analysis, exploring construct validity, internal consistency, and interpretability. Construct validity was assessed via dimensionality analyses, item fit, model fit, and threshold ordering. Internal consistency was evaluated using inter-item correlations, item-total correlations, person separation index, and Cronbach's alpha. Interpretability was examined through floor and ceiling effects. A total of 156 informal caregivers of stroke survivors participated, with 84% ( = 131) women and a median age of 58 (IQR: 49-66) years. All subscales showed unidimensionality with acceptable item and model fit and ordered thresholds. Internal consistency was excellent across all subscales. No floor and ceiling effects were observed. This study demonstrates good construct validity, internal consistency, and interpretability of the German OBI-Care. It is suitable for assessing occupational balance and may help identify and support occupational contingency in informal caregivers of stroke survivors.
在职业科学与治疗领域，活动被视为有意义的行为。对活动的数量和多样性的满意度被称为职业平衡。“非正式照料者的职业平衡”（OBI-Care）问卷通过三个子量表评估对活动的满意度：职业领域、特征和恢复力。在此过程中，它还涉及职业应变能力，即根据意外事件调整活动的能力。虽然先前的研究已证实其在其他人群中的有效性，但尚未对中风幸存者的非正式照料者的心理测量特性进行探索。本研究旨在评估德语版OBI-Care在评估该目标群体职业平衡方面的结构效度、内部一致性和适用性。使用通过在线调查收集的数据进行了一项验证研究。使用拉施评分量表分析检查了三个子量表的测量特性，探索了结构效度、内部一致性和可解释性。通过维度分析、项目拟合、模型拟合和阈值排序评估结构效度。使用项目间相关性、项目与总分相关性、人员分离指数和克朗巴哈系数评估内部一致性。通过地板效应和天花板效应检查可解释性。共有156名中风幸存者的非正式照料者参与，其中84%（=131）为女性，中位年龄为58岁（四分位间距：49 - 66岁）。所有子量表均显示出单维度性，具有可接受的项目和模型拟合以及有序阈值。所有子量表的内部一致性都非常好。未观察到地板效应和天花板效应。本研究证明了德语版OBI-Care具有良好的结构效度、内部一致性和可解释性。它适用于评估职业平衡，并可能有助于识别和支持中风幸存者非正式照料者的职业应变能力。
