The relationship between caregiving self-efficacy and depressive symptoms in family caregivers of patients with Alzheimer disease: a longitudinal study

Abstract

ABSTRACTBackground:Caregiving for a relative with dementia has been associated with negative consequences for mental health. Self-efficacy has been shown to correlate negatively with depression but the long-term association between caregiver burden, caregiver self-efficacy, and depressive symptoms, remains still largely unexplored. The aim of the present study was to evaluate whether different self-efficacy domains partially mediated the relationship between caregiving burden and depression.Methods:A three-wave design was used, with initial assessment and follow-ups three months later and one year later. One hundred seventy caregivers of patients with AD responded to measures of caregiver burden, caregiving self-efficacy, and depressive symptoms. Data were analyzed by means of structural equation models.Results:The tested model provided support for the guiding hypothesis. Burden at the time of the first assessment (T1) significantly influenced depression one year later and the relationship between burden at time one and depressive symptoms one year later was partially mediated by self-efficacy for controlling upsetting thoughts.Conclusions:The findings of the present study provide evidence that, along a considerable length of time, the effects of caregiver burden on depressive symptoms can be explained by the caregivers’ efficacy beliefs in controlling upsetting thoughts related to the caregiving tasks. Interventions for caregivers of patients with AD may help them in tackling negative thoughts about the caregiving role.
