This study aims to evaluate the effectiveness of various interventions designed to reduce caregiver burden and improve caregiver well-being.<\/jats:p><\/jats:sec><jats:sec><jats:title>Design<\/jats:title><jats:p>Meta-analysis of randomized controlled trials (RCTs).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A comprehensive literature search was conducted across multiple electronic databases, identifying randomized controlled trials (RCTs) that assessed interventions aimed at reducing caregiver burden in caregivers of chronic dyspnea patients. A total of 25 RCTs, involving 2,425 participants, were included. The included studies evaluated a variety of interventions, including psychological support, education programs, and physical activity. Data were extracted and analyzed using standardized mean differences (SMD) to assess intervention effects, with heterogeneity and publication bias considered.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 25 RCTs involving 2,425 participants were included in the meta-analysis. Interventions significantly reduced caregiver burden (SMD\u202f=\u202f\u22120.65, 95% CI \u22120.96 to \u22120.34) with notable heterogeneity (I<jats:sup>2<\/jats:sup>\u202f=\u202f82.7%). Subgroup analysis showed a more pronounced reduction in studies conducted in Asia (SMD\u202f=\u202f\u22120.80). Improvements were also observed across caregiver burden categories, with the most significant reduction in social burden (SMD\u202f=\u202f\u22121.07). Family function improved (SMD\u202f=\u202f0.53), but no significant change in social support (SMD\u202f=\u202f0.55) or quality of life (SMD\u202f=\u202f0.16) was found. Anxiety (SMD\u202f=\u202f\u22120.28) showed no significant reduction. Stress (SMD\u202f=\u202f\u22120.59) and depression (SMD\u202f=\u202f\u22120.45) were significantly reduced.
