Effects of group reminiscence on psychosocial outcomes among nursing home residents with intact cognition and mild cognitive impairment: A systematic review and meta-analysis.

Only 4 of 19 studies were randomized trials; 15 were quasi-experimental. Moderate to high heterogeneity remained for several outcomes, including life satisfaction and self-esteem. Follow-up was limited: only a small number of studies reported follow-up, ranging from 1 to 6 months. Death anxiety and loneliness were each based on only 2 studies, and publication bias could not be checked for them. Most studies were conducted in Asia-Pacific countries, and only English or Chinese studies were included. People with dementia, severe cognitive impairment, diagnosed depression, suicidal tendencies or other mental illnesses were excluded. Control conditions varied, including standard nursing care or alternative interventions.

This study was supported by the National College Students Innovation and Entrepreneurship Training Program (No. 202510371051). The authors declared no competing interests.

Do not conclude that group reminiscence reduces loneliness. The pooled effect was not statistically significant (P = 0.06), and the two studies had very high inconsistency (I2 = 95%).
