Examine the psychometric properties of the Appraisal of Caregiving Scale (ACS).
Data were collected as part of the FOCUS Program trial in Michigan (N = 484 caregivers).
Exploratory factor analysis found the ACS measured Threat, General Stress, and Benefit appraisals. Cronbach's alphas for all subscales exceeded 0.70. Construct validity analyses indicated the Threat subscale correlated significantly with concepts of avoidant coping, burden, and dyadic support (r > 0.30). General Stress correlated significantly with burden (r = 0.348) and dyadic support (r = -0.373), and the Benefit subscale correlated significantly with active coping (r = 0.444). Known group analyses indicated that depressed caregivers had higher Threat and General Stress scores than non-depressed caregivers. Also, younger caregivers reported significantly higher scores on the General Stress subscale than older caregivers. Predictive validity analyses found appraisal scores at baseline accounted for 33.3% of the variance in hopelessness and 27.8% of the variance in depression at Time 2.
The ACS is a reliable measure of Threat, General Stress, and Benefit appraisals, with some support for its validity. Health professionals may find the ACS useful for guiding intervention development. Future research should continue to examine the ACS' validity.
检验照护评估量表（ACS）的心理测量特性。
数据收集作为密歇根州聚焦项目试验的一部分（N = 484名照护者）。
探索性因素分析发现ACS测量了威胁、一般压力和益处评估。所有子量表的克朗巴哈系数均超过0.70。结构效度分析表明，威胁子量表与回避应对、负担和二元支持概念显著相关（r > 0.30）。一般压力与负担（r = 0.348）和二元支持（r = -0.373）显著相关，益处子量表与积极应对显著相关（r = 0.444）。已知组分析表明，抑郁的照护者比非抑郁的照护者有更高的威胁和一般压力得分。此外，年轻照护者在一般压力子量表上的得分显著高于年长照护者。预测效度分析发现，基线时的评估得分占第2阶段绝望感方差的33.3%和抑郁方差的27.8%。
ACS是一种可靠的威胁、一般压力和益处评估测量工具，其效度得到了一定支持。卫生专业人员可能会发现ACS有助于指导干预措施的制定。未来的研究应继续检验ACS的效度。
