Loving‐kindness and compassion meditation (LKCM) was a promising intervention for improving life satisfaction, but previous findings have been inconsistent. The current study provides a systematic review and meta‐analysis, including 23 empirical studies on LKCM with life satisfaction as an outcome variable. The primary meta‐analysis indicated that LKCM significantly enhanced life satisfaction in pre‐post design (g = 0.312, k = 15, n = 451), but the significance disappeared in the additional meta‐analysis based on randomized controlled trials (g = 0.106, k = 6, n = 404). Moderator analyses found significant effects for type of control (i.e., the effects of LKCM were inferior to active control group, but superior to waitlist condition), but not for other moderators (i.e., participant type, previous meditation experience, specific protocol, components of LKCM, combination with mindfulness mediation, and intervention length). Narrative review identified self‐compassion and positive emotions as important mediators. The practice time of LKCM had indirect but not direct association with life satisfaction. The findings supported that LKCM is promising in increasing life satisfaction, but more studies are needed to investigate the effects with more rigorous designs. Future studies should investigate other potential mechanisms and clarify whether LKCM change the reality or the perception of life.
