随着以正念为基础的干预措施越来越广泛，人们越来越有兴趣更好地了解这些治疗的哪些特点能产生有益的效果。本研究考察了正念练习时间和练习质量在预测心理功能（消极情绪、情绪调节、生活质量、正念）方面的相对贡献。数据来自吸烟者正念训练的随机临床试验，并评估治疗后（n = 43）和5个月随访（n = 38）的结果。干预包括针对戒烟和复发预防的正念技术指导，由10个小组会议组成，为期8周。数据来自8个治疗组。在治疗过程中，每周测量正念练习质量，并使用多水平模型来估计练习质量的变化轨迹。练习质量的测量被证明是有效和可靠的，练习质量的变化可以预测治疗后（β= 0.31, 95% CI =[0.04, 0.56], p = 0.022）和随访（β= 0.45 [0.16, 0.73], p = 0.002）心理功能的变化，即使在控制练习时间的情况下也是如此。练习时间可预测治疗后的预后（β= 0.31 [0.05, 0.57], p = 0.019），但在随访时无预测作用（β= 0.16 [[H11002]0.14, 0.47], p = 0.293）。戒烟后1个月和6个月，练习时间和练习质量的变化均不能预测戒烟效果。结果支持练习质量作为正念干预的一个相关方面的重要性。
As mindfulness-based interventions become increasingly widespread, interest has grown in better understanding which features of these treatments produce beneficial effects. The present study examined the relative contribution of mindfulness practice time and practice quality in predicting psychological functioning (negative affect, emotion regulation, quality of life, mindfulness). Data were drawn from a randomized clinical trial of mindfulness training for smokers and assessed outcomes at posttreatment (n = 43) and 5-month follow-up (n = 38). The intervention included instruction in mindfulness techniques targeted to smoking cessation and relapse prevention and was composed of 10 group meetings over 8 weeks. Data from 8 treatment groups were used. Mindfulness practice quality was measured weekly over the course of treatment, and multilevel modeling was used to estimate trajectories of change in practice quality. The measure of practice quality was shown to be valid and reliable, with change in practice quality predicting change in psychological functioning at both posttreatment (β= .31, 95% CI =[0.04, 0.56], p = .022) and follow-up (β= .45 [0.16, 0.73], p = .002), even when controlling for practice time. Practice time predicted outcomes at posttreatment (β= .31 [0.05, 0.57], p = .019) but not at follow-up (β= .16 [[H11002]0.14, 0.47], p = .293). Neither practice time nor change in practice quality predicted smoking abstinence at 1 month or 6 months postquit. Results support the importance of practice quality as a relevant aspect of mindfulness interventions.
