To investigate the effects of dyadic intervention on anxiety, depression, care burden and quality of life in informal caregivers of palliative patients with lung cancer. Informal caregivers of palliative lung cancer patients bear a large number of negative emotions during the process of caring for the patients. Dyadic intervention has the potential for improving them but the overall effect is unclear. A systematic review and meta-analysis. All randomized controlled trials were retrieved from the following databases until 4 May 2023: Web of Science, Embase Ovid, PubMed, Cochrane Central Register of Randomized Controlled Trials, Weipu, Wanfang and Chinese National Knowledge Infrastructure databases. This review was performed by Stata 12.0 and Review Manager 5.3. Thirteen randomized controlled trials were in accordance with the inclusion and exclusion criteria (n = 1807). The results revealed that dyadic intervention significantly improved family caregivers' anxiety, depression and caregiver burden of palliative patients with lung cancer. There was no significant difference in quality of life between the dyadic intervention group and family caregivers who did not receive the dyadic intervention. Dyadic intervention positively impacts the experience of family caregivers of palliative patients with lung cancer.
