This article assesses the extent to which formally provided comprehensive community care tends to substitute for informal care provided by family and friends to impaired elderly persons living in the community. Using simultaneous equations causal modeling techniques to control for selective targeting and other intervening factors, results, indicate a substantial tendency for formally provided care to be substituted for informal care. Other results indicate that unmet need appears to be the major variable predicting both informal and formal support levels, with informal care providers appearing to be somewhat more precise in conditioning support levels on need than formal care providers. Policy implications of these findings are discussed.
本文评估了正式提供的综合社区护理在多大程度上倾向于替代家人和朋友为居住在社区中的受损老年人提供的非正式护理。使用联立方程因果建模技术来控制选择性目标定位和其他干预因素，结果表明正式提供的护理有很大的被非正式护理替代的趋势。其他结果表明，未满足的需求似乎是预测非正式和正式支持水平的主要变量，非正式护理提供者在根据需求调整支持水平方面似乎比正式护理提供者更为精确。本文还讨论了这些发现的政策含义。
