Loving-kindness meditation (LKM) effectively enhances positive emotions, according to a systematic review and meta-analysis of 24 empirical studies involving 1,759 participants. The analysis found medium effect sizes for LKM interventions on daily positive emotions in both wait-list controlled randomized trials and non-randomized studies, and small to large effect sizes for immediate positive emotions from ongoing practice. Interventions focused specifically on loving-kindness produced medium effects, while compassion-focused interventions yielded small effects. The length of interventions and meditation time did not influence outcomes, but studies without didactic components showed small effects. Individual differences and the nature of positive emotions also affected results. More research is needed to identify active intervention components and applicability in clinical populations.
