The purpose of this study was to examine the internal structure of the Children Helping Out: Responsibilities, Expectations, and Supports (CHORES), an assessment of household task participation for children. Rasch analysis was used to examine patterns of item response and scale structure with data collected from caregivers of 132 children and youth ages 6-14 yr with and without disabling conditions. Internal consistency was strong for the total measure and the subscales. The items in both subscales fit the measurement model, and the item difficulty order matched the expected pattern from harder to easier household task performance and degree of caregiver assistance. The sample distribution in the hierarchical continuum showed that younger participants and those with physical disabilities tended to score lower. Some inconsistencies in rating scale use suggest a need for further clarification of the scoring criteria for measurement coherence.
本研究的目的是检验“儿童伸出援手：责任、期望与支持”（CHORES）的内部结构，这是一项针对儿童家务劳动参与情况的评估。采用拉施分析来检验项目反应模式和量表结构，数据收集自132名6至14岁有或无残疾状况的儿童和青少年的照料者。总量表和分量表的内部一致性很强。两个分量表中的项目均符合测量模型，且项目难度顺序与家务劳动表现从难到易以及照料者协助程度的预期模式相符。分层连续体中的样本分布表明，较年轻的参与者和身体残疾者得分往往较低。评分量表使用中的一些不一致之处表明，需要进一步澄清评分标准以确保测量的连贯性。
