Caring for someone with Lewy body disease (LBD) is difficult. This study describes the development and validity testing of the LBD Caregiver Activities Scale (LBD-CAS). Caregiver interviews informed the development of the LBD-CAS. Experts estimated the content validity of items (I-CVI) and provided feedback about the scale. Family caregivers evaluated items for face validity. Expert I-CVI ratings yielded 49 items with scores of 0.83 or higher. Four items with I-CVI scores <.83 were retained due to conceptual significance. The overall scale CVI was 0.86. Items evaluated by caregivers for face validity showed excellent variability in responses, with no major ceiling or floor effects. LBD-CAS showed evidence of content and face validity for the assessment of activities performed by LBD caregivers. Further psychometric testing is recommended.
照顾患有路易体痴呆症（LBD）的人很困难。本研究描述了路易体痴呆症照顾者活动量表（LBD-CAS）的开发和效度测试。照顾者访谈为 LBD-CAS 的开发提供了信息。专家估计了项目的内容效度（I-CVI），并对量表提供了反馈。家庭照顾者对项目进行了表面效度评估。专家 I-CVI 评分得出了 49 个得分在 0.83 或以上的项目。由于概念意义，4 个 I-CVI 得分<0.83 的项目被保留下来。总体量表 CVI 为 0.86。由照顾者评估的表面效度项目显示出极好的反应变异性，没有明显的上限或下限效应。LBD-CAS 为评估 LBD 照顾者的活动提供了内容和表面效度的证据。建议进行进一步的心理测量测试。
