Culture-based gender norms regarding who performs daily activities can bias the assessment of instrumental activities of daily living (IADL). This study evaluated item-response biases in the activities of daily living (ADL) and IADL among community-living Korean older adults.
The subjects included older Korean participants of the Korean Longitudinal Study of Ageing baseline survey (n=4,164). We performed differential item functioning (DIF) analysis of these data using the Mantel-Haenszel method.
We observed different reported levels of disability for eight IADL items among gender, age, and educational level subgroups. After matching for overall functional disability, men were more likely to report limitations in performing various household activities, compared to cognitive activities in women.
Cross-national comparisons of ADL and IADL disabilities need to consider item response bias stemming from culture-based gender norms regarding who performs different household activities.
关于日常活动由谁来执行的基于文化的性别规范可能会使对日常生活工具性活动（IADL）的评估产生偏差。本研究评估了韩国社区老年人日常生活活动（ADL）和IADL中的项目反应偏差。
研究对象包括韩国老年纵向研究基线调查的韩国老年参与者（n = 4164）。我们使用Mantel-Haenszel方法对这些数据进行了差异项目功能（DIF）分析。
我们在性别、年龄和教育水平亚组中观察到八个IADL项目报告的残疾水平不同。在匹配总体功能残疾后，与女性的认知活动相比，男性更有可能报告在进行各种家务活动方面存在限制。
ADL和IADL残疾的跨国比较需要考虑源于关于不同家务活动由谁来执行的基于文化的性别规范的项目反应偏差。
