了解行为改变技术(BCT)可以改变行为的机制对于开发和评估有效的行为干预措施非常重要。为了推进这个领域,我们需要对BCT在影响行为时可能通过的作用机制(MoAs)的共享知识。
就BCT和MoAs之间的联系达成专家共识。
在修改的标称组技术研究中,105名国际行为改变专家评级,讨论,并重新评估了61个常用BCT和26个MoAs之间的链接。达成共识的标准是,至少80%的专家就联系达成共识。热图用于呈现与所有可能的链接有关的数据。
在1,586个可能的链接(61个BCT×26个MoAs)中,61个BCT中的51个(83.6%)与一个或多个MoAs有明确的联系(平均值[SD]=1.44[0.96],范围=1-4),26个MoAs中的20个(76.9%)与一个或多个BCT有明确的联系(平均值[SD]=3.27[2.91],范围=9)。九十个(5.7%)被确定为“确定”链接,464个(29.2%)作为“绝对不是”链接,和1,032(65.1%)作为“可能”或“不确定”链接。没有确定10个BCT的“明确”链接(例如,“行动计划”和“行为替代”)以及六个MoAs(例如,\"需要\"和\"乐观\")。
BCT和MoAs之间的联系矩阵为开发和综合行为干预提供了基础。这些链接也为在未来的研究中指定实证检验提供了一个框架。
Understanding the mechanisms through which behavior change techniques (BCTs) can modify behavior is important for the development and evaluation of effective behavioral interventions. To advance the field, we require a shared knowledge of the mechanisms of action (MoAs) through which BCTs may operate when influencing behavior.
To elicit expert
consensus on links between BCTs and MoAs.
In a modified Nominal Group Technique study, 105 international behavior change experts rated, discussed, and rerated links between 61 frequently used BCTs and 26 MoAs. The criterion for
consensus was that at least 80 per cent of experts reached agreement about a link. Heat maps were used to present the data relating to all possible links.
Of 1,586 possible links (61 BCTs × 26 MoAs), 51 of 61 (83.6 per cent) BCTs had a definite link to one or more MoAs (mean [SD] = 1.44 [0.96], range = 1-4), and 20 of 26 (76.9 per cent) MoAs had a definite link to one or more BCTs (mean [SD] = 3.27 [2.91], range = 9). Ninety (5.7 per cent) were identified as \"definite\" links, 464 (29.2 per cent) as \"definitely not\" links, and 1,032 (65.1 per cent) as \"possible\" or \"unsure\" links. No \"definite\" links were identified for 10 BCTs (e.g., \"Action Planning\" and \"Behavioural Substitution\") and for six MoAs (e.g., \"Needs\" and \"Optimism\").
The matrix of links between BCTs and MoAs provides a basis for those developing and synthesizing behavioral interventions. These links also provide a framework for specifying empirical tests in future studies.
