| Annotation | Attrition in older respondents in longitudinal studies most often occurs because of death or incapacity. This study uses a subset of the. University of Southern California Longitudinal Study of the Generations (LSOG), and includes data for 208 Generations 1 and 2 parent child dyads and 538 G2-G3 dyads over a 30-year period (1970/71 to 2000). Results indicate that attrition due to mortality biased estimates of respondents' assessments of their functional health status over time, and parents' perceptions of the quality of the parent-child relationship deteriorated more rapidly among those who died by Time 7 (2000), but non-response did not seriously bias estimates of these measures. Using proxies, the authors found that functional impairment increased more rapidly when children reported about parents, especially in advanced old age. These results support the use of full information in estimating growth curves where mortality is present, but raise concerns when using child proxies to evaluate parental health on the quality of intergenerational relationships.
