The relationship between engagement in pleasant activities as rated by the patient and as rated by the caregiver from the patient's perspective was examined using structural equation modeling in a sample of patients (N = 277) diagnosed with mild to moderate Alzheimer's disease. The two activity participation ratings were only moderately related to one another. Furthermore, depression was the only significant predictor of the patient-rated activity participation, whereas severity of depression, degree of personality change, level of dependence, and cognition were all significant predictors of caregiver-rated activity participation. These findings suggest that caregivers consider a wider range of variables when evaluating the patient's engagement in activities than does the patient. Predictors of patient-rated activity participation did not differ as a function of age or cognition.
在一组被诊断为轻度至中度阿尔茨海默病的患者样本(N = 277)中,使用结构方程模型研究了患者自我评定的愉快活动参与度与照顾者从患者角度评定的愉快活动参与度之间的关系。这两种活动参与度评定之间仅存在中等程度的相关性。此外,抑郁是患者评定的活动参与度的唯一显著预测因素,而抑郁严重程度、人格改变程度、依赖水平和认知水平都是照顾者评定的活动参与度的显著预测因素。这些发现表明,与患者相比,照顾者在评估患者的活动参与度时会考虑更广泛的变量。患者评定的活动参与度的预测因素不会因年龄或认知功能而有所不同。
