Background To help implement behavior change interventions (BCIs) it is important to be able to characterize their key components and determine their effectiveness. Purpose This study assessed and compared the components of BCIs in terms of intervention functions identified using the Behaviour Change Wheel Framework (BCW) and in terms of their specific behavior change techniques (BCTs) identified using the BCT TaxonomyV1, across six behavioral domains and the association of these with cost-effectiveness. Methods BCIs in 251 studies targeting smoking, diet, exercise, sexual health, alcohol and multiple health behaviors, were specified in terms of their intervention functions and their BCTs, grouped into 16 categories. Associations with cost-effectiveness measured in terms of incremental cost-effectiveness ratio (ICER) upper and lower estimates were determined using regression analysis. Results The most prevalent functions were increasing knowledge through education (72.1%) and imparting skills through training (74.9%). The most prevalent BCT groupings were shaping knowledge (86.5%), changing behavioral antecedents (53.0%), supporting self-regulation (47.7%), and providing social support (44.6%). Intervention functions associated with better cost-effectiveness were those based on training (βlow = −15044.3; p = .002), persuasion (βlow = −19384.9; p = .001; βupp = −25947.6; p < .001) and restriction (βupp = −32286.1; p = .019), and with lower cost-effectiveness were those based on environmental restructuring (β = 15023.9low; p = .033). BCT groupings associated with better cost-effectiveness were goals and planning (βlow = −8537.3; p = .019 and βupp = −12416.9; p = .037) and comparison of behavior (βlow = −13561.9, p = .047 and βupp = −30650.2; p = .006). Those associated with lower cost-effectiveness were natural consequences (βlow = 7729.4; p = .033) and reward and threat (βlow = 20106.7; p = .004). Conclusions BCIs that focused on training, persuasion and restriction may be more cost-effective, as may those that encourage goal setting and comparison of behaviors with others.

与成本效益相关的行为干预组件：六个领域的比较

背景 为了帮助实施行为改变干预 (BCI)，重要的是能够描述其关键组成部分并确定其有效性。目的 本研究评估和比较 BCI 的组成部分，根据使用行为改变轮框架 (BCW) 确定的干预功能和使用 BCT 分类法 V1 确定的特定行为改变技术 (BCT)，跨越六个行为领域和关联其中具有成本效益。方法 251 项针对吸烟、饮食、运动、性健康、酒精和多种健康行为的研究中的 BCI，根据其干预功能和 BCT 进行详细说明，分为 16 类。使用回归分析确定了以增量成本效益比 (ICER) 上限和下限估计的成本效益与成本效益的关联。结果最普遍的功能是通过教育增加知识（72.1%）和通过培训传授技能（74.9%）。最普遍的 BCT 分组是塑造知识 (86.5%)、改变行为前因 (53.0%)、支持自我调节 (47.7%) 和提供社会支持 (44.6%)。与更好的成本效益相关的干预功能是基于培训（βlow = -15044.3；p = .002）、说服（βlow = -19384.9；p = .001；βupp = -25947.6；p <.001）和限制的干预功能(βupp = -32286.1; p = .019)，成本效益较低的是基于环境重组的那些 (β = 15023.9low; p = .033)。与更好的成本效益相关的 BCT 分组是目标和计划（βlow = -8537.3；p = .019 和 βupp = -12416.9；p = .037）和行为比较（βlow = -13561.9，p = .047 和 βupp = −30650.2；p = .006）。与较低成本效益相关的是自然后果（βlow = 7729.4；p = .033）和奖励和威胁（βlow = 20106.7；p = .004）。结论 专注于培训、说服和限制的 BCI 可能更具成本效益，鼓励目标设定和与他人行为比较的 BCI 也可能更具成本效益。033）以及奖励和威胁（βlow = 20106.7；p = .004）。结论 专注于培训、说服和限制的 BCI 可能更具成本效益，鼓励目标设定和与他人行为比较的 BCI 也可能更具成本效益。033）以及奖励和威胁（βlow = 20106.7；p = .004）。结论 专注于培训、说服和限制的 BCI 可能更具成本效益，鼓励目标设定和与他人行为比较的 BCI 也可能更具成本效益。
