The Moderating Role of Pain Self-efficacy in the Relationships Among Caregiver Burden and Care Recipient Pain and Neuropsychiatric Symptoms in a Sample of Persons With Dementia.

Abstract

Past research suggests relationships among dementia caregiver burden and care recipient pain and neuropsychiatric symptoms, but no prior work has examined the influence of pain self-efficacy on these associations. A sample of 502 dementia caregivers completed an online protocol assessing caregiver burden and care recipient neuropsychiatric symptoms, presence of pain, and pain self-efficacy in this cross-sectional, observational study. The indirect effect of neuropsychiatric symptoms on the relationship between pain and caregiver burden was significant. Pain self-efficacy significantly moderated the effect of pain on neuropsychiatric symptoms (P=0.04) and the direct association between pain and caregiver burden (P=0.004), but did not moderate the indirect effect. Future research should explore how pain influences neuropsychiatric symptoms, and whether improvement in pain self-efficacy in dementia care recipients attenuates the influence of pain on neuropsychiatric symptoms and caregiver burden in other samples.
