A Brief Advance Care Planning Education Intervention for Socioeconomically Disadvantaged Dementia Caregivers: A Single-Group Pretest–Posttest Study

Introduction: Family caregivers of people with dementia play an essential role in advance care planning (ACP), yet engagement remains low among socioeconomically disadvantaged caregivers. This study evaluated a brief video- and leaflet-based ACP intervention. Methods : A single-group pretest–posttest study was conducted with 47 dementia caregivers recruited from public health centers providing home-visiting services. Participants received a 30-minute ACP intervention. Outcomes included decisional conflict, ACP engagement, and ACP-related perspectives, assessed at baseline and 1-month post-intervention using paired t-tests. Results : Participants demonstrated significant improvements in ACP-related knowledge ( d = 0.37, p = .014), decisional conflict ( d = 0.44, p = .004), and ACP engagement ( d = 0.64, p < .001) at 1-month follow-up. No significant changes were found in ACP-related attitudes, perceived benefits, or perceived barriers. Discussion : Brief ACP education reduced decisional conflict and improved engagement, indicating its potential value. Further controlled studies are needed to assess long-term psychosocial effects.
