We examined the wear-and-tear hypothesis using data from 4 annual interviews with 130 (128 White) middle-aged daughters caring for their physically impaired, elderly mothers. We formulated a latent growth curve model hypothesizing that increases in the amount of care given by daughters caused a decrease in caregiving satisfaction, independent of caregiving duration. We found considerable individual variability and change in both caregiving satisfaction and the amount of care given in univariate latent growth curve analyses. Contrary to the wear-and-tear hypothesis, a multivariate latent growth curve analysis revealed duration of caregiving had no effect on either initial caregiving satisfaction or change in satisfaction. An elaborated wear-and-tear model was supported, however. The mechanism for decline in satisfaction is an increase in the amount of care given.
我们利用对130名（128名白人）中年女儿进行的4次年度访谈数据，这些女儿负责照顾身体有残疾的年迈母亲，以此检验损耗假说。我们构建了一个潜在增长曲线模型，假设女儿提供的照料量增加会导致照料满意度下降，且与照料持续时间无关。在单变量潜在增长曲线分析中，我们发现照料满意度和提供的照料量都存在相当大的个体差异和变化。与损耗假说相反，多变量潜在增长曲线分析显示，照料持续时间对初始照料满意度或满意度变化均无影响。然而，一个经过细化的损耗模型得到了支持。满意度下降的机制是提供的照料量增加。
