This review assesses interventions to reduce loneliness in Chinese older adults, analyzing 36 studies involving 3965 participants. Focusing on individuals aged 50 and over, the meta-analysis reveals a significant overall effect size (Hedges' g = 0.937, 95% CI [0.71,1.16], p<0.001), highlighting the effectiveness of psychological and mixed-method approaches. Despite promising results, methodological concerns suggest cautious interpretation. Future research should aim to refine intervention quality and examine the impact of technology-supported methods on loneliness.
