行为干预通常包括多种行为改变技术(BCT)。为干预选择BCT的理论可能是明确的，也可能是不报告的，从而阻碍了理论和行为改变结果之间的联系的确定。这项研究的目的是确定在行为改变干预中通常一起出现的BCT组，并检查是否可以确定这些组的行为改变理论。这项研究包括三个阶段：(A)因素分析，以从277份行为改变干预报告中确定共同出现的BCT组；(B)检查专家对BCT组与行为理论之间的联系的共识(n=25)；(C)将专家联系的理论与277份干预报告作者明确提到的理论进行比较。通过因子分析确定了五组共发生的BCT(范围为每组3-13个BCT)。专家们同意五个环节(≥80%的专家)，包括三个最佳行为测试小组和五个行为改变理论。研究作者在干预报告中使用了类似的bct组，也陈述了专家同意的五个bct群体理论联系中的四个。有可能确定在干预中经常一起使用的BCT组。专家们对这些BCT小组背后的行为改变理论做出了共同的推断，表明有可能为作者没有明确提出理论的干预提出一个理论基础。这些结果促进了我们对多成分干预理论应用的理解，并为进一步理解基于理论的干预发展和评估奠定了证据基础。行为改变干预背后的理论对于理解它们如何起作用以及为什么起作用很重要，但可能不会在已发表的报告中得到明确阐述。这项研究发现，通过观察这些干预措施中使用的行为改变技术的组合，行为改变专家可以同意其中一些理论。
Behavioral interventions typically include multiple behavior change techniques (BCTs). The theory informing the selection of BCTs for an intervention may be stated explicitly or remain unreported, thus impeding the identification of links between theory and behavior change outcomes. This study aimed to identify groups of BCTs commonly occurring together in behavior change interventions and examine whether behavior change theories underlying these groups could be identified. The study involved three phases: (a) a factor analysis to identify groups of co-occurring BCTs from 277 behavior change intervention reports; (b) examining expert consensus (n = 25) about links between BCT groups and behavioral theories; (c) a comparison of the expert-linked theories with theories explicitly mentioned by authors of the 277 intervention reports. Five groups of co-occurring BCTs (range: 3–13 BCTs per group) were identified through factor analysis. Experts agreed on five links (≥80% of experts), comprising three BCT groups and five behavior change theories. Four of the five BCT group–theory links agreed by experts were also stated by study authors in intervention reports using similar groups of BCTs. It is possible to identify groups of BCTs frequently used together in interventions. Experts made shared inferences about behavior change theory underlying these BCT groups, suggesting that it may be possible to propose a theoretical basis for interventions where authors do not explicitly put forward a theory. These results advance our understanding of theory use in multicomponent interventions and build the evidence base for further understanding theory-based intervention development and evaluation. The theory underlying behavior change interventions is important for understanding how and why they work, but may not be made explicit in published reports. This study found that experts in behavior change can agree on some of these theories by looking at the combinations of behaviour change techniques used in these interventions.
