Abstract

Background: Recruiting older adults, their family members and their home care workers as participants in research studies is particularly complicated. This might be due to medical or cognitive problems of the older adult as well as the high workload and shortage of time experienced by caregivers. The present study compared the contribution of two different versions of an advanced letter followed by two different versions of a recruitment phone call to the cooperation rate of older adults, family caregivers and home care workers in a face-to-face survey. Methods: A quasi-experimental design was used to compare the contribution of the different types of appeal. A total of 2,014 caregiving units (composed of an older adult, a family member and a home care worker) were randomly sampled from a list of Israeli long-term care insurance beneficiaries. 74.32% of the sampled caregiving units were eligible to participate in the study. The first group of participants received formal and succinctly phrased written and oral appeals - an advanced letter followed by a recruitment phone call. The second group of participants received the original formal and succinctly phrased advanced letter, but a revised recruitment phone call that included a more personal approach, the provision of broader information about the study and the avoidance of words with a possible negative connotation. The third group of participants received both a revised advanced letter and a revised recruitment phone call. Results: Using the succinctly phrased written and oral appeals, we had a cooperation rate of about 50% for the entire caregiving unit. Using a revised advanced letter and a revised recruitment phone call yielded an increase of 20-25% in the cooperation rate for the entire caregiving unit. Using the revised recruitment phone call and the original advanced letter yielded an increase in the cooperation rate only among migrant home care workers. Conclusion: This study showed that by changing the format of appeal we can increase the cooperation rate of older adults and their caregivers in a research survey. This study also pointed out the importance of the advanced letter.
