Depressive Symptoms Among Caregivers of Older Adults With Both Diabetes and Functional Limitations and Moderation by Caregiver Expressive Social Support.

Purpose: The purpose of the study was to explore how caring for older adults with both diabetes and functional limitations impacts caregiver depressive symptoms and whether this impact is moderated by caregivers' expressive social support and psychological resilience.

Method: Cross-sectional data of 278 dyads, each comprising an older adult with functional limitations and his/her primary family caregiver were analyzed. Older adult diabetes status (yes/no) was based on ever-diagnosis of diabetes. Caregiver depressive symptoms, expressive social support, and psychological resilience were measured using standard scales. Multivariable linear regression was used to assess the association of interest and its moderation by caregiver expressive social support and psychological resilience.

Results: Caregivers of older adults with both diabetes and functional limitations had a higher depressive symptoms score compared to caregivers of older adults with only functional limitations. This association was inversely moderated by caregiver expressive social support. As caregiver expressive social support increased, the difference in depressive symptoms between caregivers of older adults with diabetes and functional limitations and caregivers of older adults with only functional limitations reduced.

Conclusion: Family caregivers of older adults with functional limitations and diabetes have a higher depressive symptoms score. However, enhancing caregiver expressive social support could mitigate this risk. Service providers should prioritize support for caregivers in such vulnerable situations and strive to enhance their expressive social support.
