| Annotation | Loss to follow-up is a problem in longitudinal studies - such as with the US Longitudinal Study of Aging (LSOA) - and the literature on response rates in panels of older people suggests that they may be more vulnerable to non-random attrition and its consequent biases. The event history used in this study to determine correlates of non-response examines important shortcomings of previous analyses, by incorporating time-varying co-variates. Non-response is not random: older people, who are less well-educated, live alone, rent (not own), have more functioning impairments, or have another sample person in the household are more likely to become non-respondents. However, correction accounting for the effect of these correlates of non-response, as well as unobserved characteristics and the probability of non-response is not large enough to introduce bias. While these results cannot be applied to other analyses or panels, they do indicate that in this case, significant non-random non-response does not bias all related analytic results. |
