背景:支持慢性健康状况患者行为改变的干预措施越来越多地使用患者群体作为分娩方式,但是这些设计通常没有考虑可以影响干预结果的小组过程。本文概述了一种设计基于群体的行为改变干预措施的新方法,该方法优先考虑将接收者共享的社会身份作为群体成员,以促进采用既定的行为改变技术(BCT)。该方法通过一个示例进行说明,该示例来自针对严重肥胖人群的研究。
方法:与利益相关者合作进行了优先级排序过程,包括行为改变专家,临床医生,和一个以前的病人来开发一个基于证据的,通过社会认同方法对健康进行分组干预。报告了发展的三个阶段:(1)确定健康问题;(2)描绘干预机制和BCT用于团体交付的操作;(3)干预手册。第四阶段,干预测试和优化,在其他地方报道。
结果:开发了基于群体的行为改变干预措施,包括12次小组会议和3次一对一磋商。干预旨在支持接受者之间共同的社会认同的发展,在提供循证BCT的同时,以提高重度肥胖患者成功干预的可能性和健康结果。
结论:手动干预,通过对健康的社会认同方法,是在利益相关者的投入下系统地设计的。所采用的开发方法可以为计划基于团体的交付的其他健康环境中的行为干预措施的设计提供信息。
BACKGROUND: Interventions to support behaviour change in people living with chronic health conditions increasingly use patient groups as the mode of delivery, but these are often designed without consideration of the group processes that can shape intervention outcomes. This article outlines a new approach to designing group-based behaviour change interventions that prioritizes recipients\' shared social identity as group members in facilitating the adoption of established behaviour change techniques (BCTs). The approach is illustrated through an example drawn from research focused on people living with severe obesity.
METHODS: A prioritization process was undertaken in collaboration with stakeholders, including behaviour change experts, clinicians, and a former patient to develop an evidence-based, group intervention informed by the social identity approach to health. Three phases of development are reported: (1) identification of the health problem; (2) delineation of intervention mechanisms and operationalization of BCTs for group delivery and (3) intervention manualization. The fourth phase, intervention testing and optimization, is reported elsewhere.
RESULTS: A group-based behaviour change intervention was developed, consisting of 12 group sessions and 3 one-to-one consultations. The intervention aimed to support the development of shared social identity among recipients, alongside the delivery of evidence-based BCTs, to improve the likelihood of successful intervention and health outcomes among people living with severe obesity.
CONCLUSIONS: A manualized intervention, informed by the social identity approach to health, was systematically designed with input from stakeholders. The development approach employed can inform the design of behavioural interventions in other health contexts where group-based delivery is planned.
