The spouse caregivers of 406 patients with Alzheimer's disease were randomly assigned to an enhanced counseling and support intervention or to a usual care control condition. Structured interviews were conducted to assess changes in social support and psychosocial outcomes for the 312 caregivers who provided care in the home for at least 1 year. The number of support persons, satisfaction with the support network, and support persons' assistance with caregiving all increased significantly as a function of the intervention. Structural equation models indicated increased satisfaction with the social support network mediated a significant proportion of the intervention's impact on caregiver depression. A portion of this mediated effect was further mediated by changes in caregiver stress appraisals. Implications for strengthening intervention programs for spouse caregivers of individuals with Alzheimer's disease are discussed.
406名阿尔茨海默病患者的配偶照料者被随机分配到强化咨询与支持干预组或常规护理对照组。对312名在家中提供护理至少1年的照料者进行了结构化访谈，以评估社会支持和心理社会结果的变化。作为干预的一项功能，支持人员的数量、对照料支持网络的满意度以及支持人员在照料方面的协助均显著增加。结构方程模型表明，对照料支持网络满意度的提高在很大程度上介导了干预对照料者抑郁的影响。这种介导效应的一部分进一步由照料者压力评估的变化所介导。文中讨论了对加强阿尔茨海默病患者配偶照料者干预项目的启示。
