Abstract

While it has been suggested that loving-kindness meditation (LKM) is an effective practice for promoting positive emotions, the empirical evidence in the literature remains unclear. Here, we provide a systematic review of 24 empirical studies (N = 1759) on LKM with self-reported positive emotions. The effect of LKM on positive emotions was estimated with meta-analysis, and the influence of variations across LKM interventions was further explored with subgroup analysis and meta-regression. The meta-analysis showed that (1) medium effect sizes for LKM interventions on daily positive emotions in both wait-list controlled RCTs and non-RCT studies; and (2) small to large effect sizes for the on-going practice of LKM on immediate positive emotions across different comparisons. Further analysis showed that (1) interventions focused on loving-kindness had medium effect size, but interventions focused on compassion showed small effect sizes; (2) the length of interventions and the time spent on meditation did not influence the effect sizes, but the studies without didactic components in interventions had small effect sizes. A few individual studies reported that the nature of positive emotions and individual differences also influenced the results. In sum, LKM practice and interventions are effective in enhancing positive emotions, but more studies are needed to identify the active components of the interventions, to compare different psychological operations, and to explore the applicability in clinical populations.

  • Previous systematic reviews and meta-analyses have tended to focus on one specific type of meditation practice, negative emotions, or self-focused positive emotions.

    “Previous systematic reviews and meta-analyses have tended to focus on one specific type of meditation practice (e.g., mindfulness or LKM; Galante et al., 2014; Zeng et al., 2015;), negative emotions (Hofmann et al., 2010), or self-focused positive emotions (e.g., Zeng et al., 2015).”

    The Abstract identifies this as a systematic review and meta-analysis of loving-kindness meditation, supporting its use as an example of a review focused on one type of practice. But the Introduction says it examines other-focused as well as self-focused positive emotions, so it does not support describing its focus as self-focused positive emotions alone. The negative-emotions clause cites a different source. (LLM, conf=0.88)

  • Other previous studies have found some differences in emotional outcomes across meditation types.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
