Standardized mindfulness-based stress reduction (MBSR) has been proved to be effective across many populations while the time commitment for the standardized intervention leads to high attrition rate. To address the problem, there has been a growing interest in conducting a single component of MBSR such as body scan. However, the impact of a sole mindfulness-based intervention (MBI) remains unclear. The aim of this study was to investigate the effects of body scan meditation. A search of databases, including PubMed, Embase, EBSCO, Cochrance, Proquest Dissertations, and Theses, was conducted for randomized controlled trials with no population restriction. Fourteen independent articles were identified and outcomes were divided into seven categories. A meta-analysis with robust variance estimation was conducted separately for different outcome categories. Body scan only had small effect on mindfulness when compared with passive control (Hedge's g = .268, 95% CI = [0.032, 0.504], p < .05). The attrition rate of long-term interventions was low. The quality of these studies was low. There was high heterogeneity across studies. A sole body scan meditation is not effective enough to improve health-related outcomes.

身体扫描冥想的影响：系统回顾和荟萃分析

标准化的基于正念的减压（MBSR）已被证明在许多人群中是有效的，而标准化干预的时间投入会导致高流失率。为了解决这个问题，人们对进行 MBSR 的单个组件（例如身体扫描）的兴趣越来越大。然而，单一的基于正念的干预（MBI）的影响仍不清楚。这项研究的目的是调查身体扫描冥想的效果。对包括 PubMed、Embase、EBSCO、Cochrance、Proquest Dissertations 和 Thes 在内的数据库进行了搜索，以寻找没有人群限制的随机对照试验。确定了十四篇独立文章，结果分为七类。对不同的结果类别分别进行了具有稳健方差估计的荟萃分析。与被动控制相比，身体扫描对正念的影响很小（Hedge'sg  = .268, 95% CI = [0.032, 0.504], p  < .05)。长期干预的流失率很低。这些研究的质量很低。研究之间存在高度异质性。单独的身体扫描冥想不足以改善与健康相关的结果。
