Psychosocial interventions support informal caregivers of people with dementia, but their impact on anticipatory grief and related health outcomes remains unclear. This review examines the effectiveness of different psychosocial approaches in addressing these outcomes.

A systematic review and meta-analysis were conducted following PRISMA guidelines and registered in PROSPERO (CRD42024629388). Eight databases were searched from inception to January 10, 2025. Two reviewers independently screened studies, assessed bias, and extracted data. Leave-one-out sensitivity and subgroup analyses addressed heterogeneity. Evidence quality was assessed using the GRADEpro Guideline Development Tool.

Eleven interventional studies were included. Psychosocial interventions (n = 6) had no significant short-term (<1 month: SMD = −0.57, 95% CI: [−1.14, 0.01], p = .05, I² = 85%) or medium-term (1–6 months; SMD = −0.76, 95% CI: [−1.99, 0.46], p = .22, I² = 88%, n = 3) effect on anticipatory grief but showed improvement in the long term (≥6 months; MD = −0.41, 95% CI: [−0.62, −0.20], p = .0001, I² = 0%, n = 2). Short-term reductions in depression were also observed, with no significant effects in other outcomes. Subgroup analyses did not identify frameworks or delivery methods linked to better outcomes. The GRADEpro rated the evidence as “Low” to “Very Low.”

Overall, psychosocial interventions have limited short- and medium-term impact on anticipatory grief. Individual, technology-mediated cognitive-behavioral approaches may improve anticipatory grief in long term, but evidence is limited. Further research should clarify the concept of anticipatory grief and evaluate interventions in large, rigorous RCTs.
