To critique social support and caregiver burden studies for (a) explication of constructs, (b) associations between constructs, (c) statistical conclusion validity, and (d) generalizability. Social support moderates caregiver burden, yet studies using different conceptualizations raise questions about validity. FRAMEWORK AND SCOPE: Cooper's (1984) methodology for an integrated literature review was used to examine 50 studies (1980-1995) involving adult caregivers of older family members.
Inadequate explication of social support, potential spuriousness and reverse causation, threats to statistical conclusion validity, and lack of generalizability were found.
Progress has been made in caregiving and social support research, yet many problems remain. Future research should include multiple measures of support, controls for spuriousness and reverse causation, valid and reliable instruments, and samples of diverse populations.
对社会支持和照料者负担研究进行批判性分析，内容包括：（a）概念阐释；（b）概念之间的关联；（c）统计结论效度；（d）可推广性。社会支持可减轻照料者负担，但采用不同概念化方式的研究引发了效度方面的问题。框架与范围：采用库珀（1984年）进行综合文献综述的方法，对50项研究（1980 - 1995年）进行考察，这些研究涉及老年家庭成员的成年照料者。
发现社会支持的阐释不足、存在潜在的虚假性和反向因果关系、对统计结论效度构成威胁以及缺乏可推广性。
照料和社会支持研究已取得进展，但仍存在许多问题。未来的研究应包括多种支持测量方法、对虚假性和反向因果关系的控制、有效且可靠的工具以及不同人群的样本。
