The purpose of this measurement study was to examine the Scale of Body Connection (SBC) sensitivity to change among mind-body or bodywork interventions and to explore the concurrent validity in relation to emotion dysregulation and mindfulness skills. This study was based on multiple clinical trials that had used the SBC to evaluate changes in body awareness (BA) and bodily dissociation (BD) in response to a mind-body or bodywork intervention. To test for sensitivity to change, tests were used to examine change and estimate effect sizes. To explore convergent validity, Pearson's product-moment correlations between the SBC subscales and Five-Facet Mindfulness Questionnaire (FFMQ) and Difficulties in Emotion Regulation Scale (DERS) were calculated among a subset of the studies, which also included these measures. The BA and BD scales consistently detected significant positive responses to a range of intervention types (yoga, mindfulness meditation, BA, multimodal therapy, and bodywork), demonstrating SBC sensitivity to change. With a few exceptions, the effect sizes across studies for BA were above 0.35, indicating near moderate-to-large effect sizes. The effect sizes for BD, as a measure of responsiveness, were much smaller than for BA; however, four of the studies had effect sizes between 0.54 and 0.86. Concurrent validity with the DERS was supported by moderate-to-large correlations, and with the FFMQ, it was significant with the BA scale in one included study. The results of this study further establish SBC validity and sensitivity to change across a range of mind-body therapies and confirm prior findings of moderate-to-strong internal consistency reliability. The findings support the use of this brief scale to assess key dimensions of BA and BD in practice and research.
本研究旨在检验躯体连接量表（SBC）对身心或身体干预措施的变化的敏感性，并探讨与情绪失调和正念技能的同时效度。这项研究基于多项临床试验，这些临床试验使用 SBC 来评估身心或身体干预措施对身体意识（BA）和身体分离（BD）的变化。为了测试变化的敏感性，使用检验来检查变化并估计效应大小。为了探索同时效度，在这些研究的一个子集中计算了 SBC 分量表与五因素正念问卷（FFMQ）和情绪调节困难量表（DERS）之间的皮尔逊积差相关，这些研究也包括这些措施。BA 和 BD 量表一致地检测到对一系列干预类型（瑜伽、正念冥想、BA、多模态治疗和身体工作）的显著正向反应，表明 SBC 对变化敏感。除了少数例外，BA 的研究之间的效应大小都大于 0.35，表明接近中到大的效应大小。作为反应性的 BD 的效应大小比 BA 小得多；然而，四项研究的效应大小在 0.54 到 0.86 之间。与 DERS 的同时效度得到中等到大相关性的支持，与 FFMQ 的同时效度在一项纳入的研究中与 BA 量表显著相关。这项研究的结果进一步确立了 SBC 在一系列身心治疗中的有效性和变化敏感性，并证实了先前关于中等至强内部一致性可靠性的发现。这些发现支持使用这种简短的量表来评估实践和研究中 BA 和 BD 的关键维度。
