Attrition in Longitudinal Studies Using Older Adults: A Meta-Analysis

Attrition in Longitudinal Studies Using Older Adults: A Meta-Analysis

Date: December 2005
Creator: Rhodes, Anthony Ryan
Description: Longitudinal methods have become an improved and essential means of measuring intra-individual change over time. Yet one of the greatest and most hazardous drawbacks studying participants over multiple sessions can be the loss of participants over time. This study attempts to illuminate the problem of attrition in longitudinal research by estimating the mean effect sizes for participant loss across 57 studies published in 13 prestigious journals which regularly use older participants. Results estimate overall attrition to be around 34% of the original sample. The subsequent break down of attrition into its subtypes yield mean effect sizes for attrition due to Refusal (8%), Loss of contact (10%), Illness (6%), and Death (14%) in studies sampling from adults 50 years or older. Analyses were then conducted via meta-analytic one-way ANOVA and weighted regression to identify possible moderators of overall attrition and their four subtypes.

Creator: Davis, Shanna R.
Description: The occurrence of custodial grandparents is increasing greatly. These grandparents face added stress and many adversities that arise from caregiving. Findings of current research tends to be mixed on the effects of grandparents raising grandchildren experience. Much research concludes that grandparent caregivers experience negative declines in overall health and well-being, while other research points out that the caregiving role may actually be a positive experience for the grandparent. The current study hypothesizes that mixed research may be a result of varying levels of resilience in the custodial grandparent population. The model proposed in this study looks at resilience as a mediator between several variables that effect custodial grandparenting. The current sample consisted of 239 custodial grandparents. A regression/correlation analysis was conducted on the data, and it was found that resilience levels were significant in mediating the effects of grandparent caregiving.
