看护者活动时间调查 (CATS) 于 1990 年制定,在用于由 Hoechst Roussel Pharmaceuticals Inc.(现为 Hoechst Marion Roussel Pharmaceuticals)进行的 Mentaneo(马来酸维纳克林)长期研究之前,进行了两次试点测试和修订。该仪器产生比率水平数据,并且依靠护理人员每项任务的分钟报告,比其他主观评级更客观,理论上更明确。非正式量表的总体 alpha 值为 0.51,表明内部一致性适度,这并不奇怪,因为护理任务​​比假定利用一个维度的量表上的项目更加离散。各个项目的重测可靠性表明 J0 周内分数具有良好的可重复性。CATS 与多种认知功能测量之间显示的紧密关系证明了与标准相关的有效性。纵向数据支持 CATS 对疾病严重程度变化的敏感性。专家小组的评级表明,非正式护理和正式或付费护理 CATS 量表的内容效度都非常好到极好
The CaregiverActivities Time Survey (CATS) was developed in 1990, pilot tested and revised twice before its use in a long-term study of Mentaneo (velnacrine maleate), conducted by Hoechst Roussel Pharmaceuticals Inc. (currently Hoechst Marion Roussel Pharmaceuticals). The instrument yields ratio level data and, by relying on caregivers' reports of minutes per task, is more objective and theoretically less ambiguous than other subjective ratings. Overall alpha of the informal scale is .51 suggesting modest internal consistency which is not surprising given that caregiving tasks are more discrete than items on scales presumed to tap one dimension. Test-retest reliability of individual items suggests good reproducibility of scores over a J0-week period Criterion-related validity was demonstrated by the strmng relationships shown between the CATS and several measures of cognitive functioning. Longitudinal data support the CATS'sensitivity to change in disease severity. Ratings by a panel of experts suggest very good to excellent content validity of both informal caregiving andformal or paid caregiving CATS scales
