In a study of eighty-four patient/caregiver dyads with mainly mild to moderate Alzheimer’s disease, Gallagher et al. (2011c) examined the relationship between self-efficacy for dementia management and symptoms of burden and depression among caregivers.
They found that self-efficacy for symptom management of those with mild to moderate dementia directly impacts on the psychological health of caregivers, while among those with moderate to severe dementia, self-efficacy was more likely to mediate the relationship between the two. They also found that self-efficacy may act as a buffer against the impact of behavioural symptoms on caregiver depression and burden.
