Loving-kindness and compassion meditations (LKCM) are considered a promising practice for increasing long-term well-being. While previous studies have mainly focused on meditation practice quantity, the current study provides an initial exploration of the quality of meditation during multiweek LKCM training. Data were collected through offline (Study 1; N = 41) and online (Study 2; N = 243) LKCM interventions. Quality of meditation was measured using two kinds of difficulties experienced during LKCM each week/unit (i.e., difficulty in concentration and difficulty in generating prosocial attitudes). Subjective well-being (SWB) was assessed by life satisfaction before and after training as well as positive and negative emotions each week/unit. Two studies consistently suggested that meditation quality was significantly associated with changes in SWB. Study 1 even showed that quality had a stronger association with SWB than did meditation quantity. Moreover, both short-term (measured each week/unit) and long-term (measured across the entire training period) associations between the quality of meditation and SWB were significant. Focusing on meditation quality, our findings provide theoretical and methodological pathways for understanding the contribution of meditation practice to LKCM training, which is helpful for guiding future research and best practices.

慈悲冥想 (LKCM) 被认为是增加长期幸福感的一种很有前途的修行方式。虽然之前的研究主要集中在冥想练习量上，但目前的研究提供了对多周 LKCM 训练期间冥想质量的初步探索。通过离线（研究 1；N  = 41）和在线（研究 2；N = 243) LKCM 干预。冥想的质量是使用每周/单位 LKCM 期间遇到的两种困难来衡量的（即难以集中注意力和难以产生亲社会态度）。主观幸福感 (SWB) 通过训练前后的生活满意度以及每周/单位的积极和消极情绪进行评估。两项研究一致表明，冥想质量与 SWB 的变化显着相关。研究 1 甚至表明，与冥想数量相比，质量与 SWB 的关联更强。此外，冥想质量与 SWB 之间的短期（每周/单位测量）和长期（在整个训练期间测量）关联均显着。专注冥想品质，
