Group-based interventions are widely used to promote health-related behaviour change. While processes operating in groups have been extensively described, it remains unclear how behaviour change is generated in group-based health-related behaviour-change interventions. Understanding how such interventions facilitate change is important to guide intervention design and process evaluations. We employed a mixed-methods approach to identify, map and define change processes operating in group-based behaviour-change interventions. We reviewed multidisciplinary literature on group dynamics, taxonomies of change technique categories, and measures of group processes. Using weight-loss groups as an exemplar, we also reviewed qualitative studies of participants’ experiences and coded transcripts of 38 group sessions from three weight-loss interventions. Finally, we consulted group participants, facilitators and researchers about our developing synthesis of findings. The resulting ‘Mechanisms of Action in Group-based Interventions’ (MAGI) framework comprises six overarching categories: (1) group intervention design features, (2) facilitation techniques, (3) group dynamic and development processes, (4) inter-personal change processes, (5) selective intra-personal change processes operating in groups, and (6) contextual influences. The framework provides theoretical explanations of how change occurs in group-based behaviour-change interventions and can be applied to optimise their design and delivery, and to guide evaluation, facilitator training and further research.

确定基于群体的健康行为改变干预措施中的变化过程:在基于群体的干预措施(MAGI)框架中制定行动机制。

以小组为基础的干预措施被广泛用于促进与健康相关的行为改变。虽然已经广泛描述了在团体中运作的过程,但仍不清楚如何在基于团体的健康相关的行为改变干预中产生行为改变。了解此类干预如何促进变革对于指导干预设计和过程评估非常重要。我们采用混合方法来识别、映射和定义在基于群体的行为改变干预中运行的改变过程。我们回顾了关于群体动力学、变革技术类别分类和群体过程测量的多学科文献。以减肥小组为例,我们还回顾了对参与者体验的定性研究和来自三种减肥干预措施的 38 次小组会议的编码记录。最后,我们就我们正在开发的研究结果综合咨询了小组参与者、促进者和研究人员。由此产生的“团体干预行动机制”(MAGI)框架包括六个总体类别:(1)团体干预设计特征,(2)促进技术,(3)团体动态和发展过程,(4)人际交往变化过程,(5)选择性的个人内部变化过程在群体中运作,以及(6)环境影响。该框架为基于群体的行为改变干预如何发生变化提供了理论解释,并可用于优化其设计和交付,并指导评估、促进者培训和进一步研究。由此产生的“团体干预行动机制”(MAGI)框架包括六个总体类别:(1)团体干预设计特征,(2)促进技术,(3)团体动态和发展过程,(4)人际交往变化过程,(5)选择性的个人内部变化过程在群体中运作,以及(6)环境影响。该框架为基于群体的行为改变干预如何发生变化提供了理论解释,并可用于优化其设计和交付,并指导评估、促进者培训和进一步研究。由此产生的“团体干预行动机制”(MAGI)框架包括六个总体类别:(1)团体干预设计特征,(2)促进技术,(3)团体动态和发展过程,(4)人际交往变化过程,(5)选择性的个人内部变化过程在群体中运作,以及(6)环境影响。该框架为基于群体的行为改变干预如何发生变化提供了理论解释,并可用于优化其设计和交付,并指导评估、促进者培训和进一步研究。(5) 选择性的个人内部变化过程在群体中运作,以及 (6) 环境影响。该框架为基于群体的行为改变干预如何发生变化提供了理论解释,并可用于优化其设计和交付,并指导评估、促进者培训和进一步研究。(5) 选择性的个人内部变化过程在群体中运作,以及 (6) 环境影响。该框架为基于群体的行为改变干预如何发生变化提供了理论解释,并可用于优化其设计和交付,并指导评估、促进者培训和进一步研究。
