This paper describes a conceptual framework of maintenance of physical activity (PA) and its application to future intervention design.
Evidence from systematic literature reviews and in-depth (N = 27) qualitative interviews with individuals with cancer were used to develop a conceptual framework of long-term physical activity behaviour. Determinants of long-term PA were listed and linked with domains of the Theoretical Domains Framework which in turn were linked to associated behaviour change techniques (BCTs) and finally to proposed mechanisms of action (MoA).
The conceptual framework is presented within the context of non-modifiable contextual factors (such as demographic and material resources) and in the presence of learnt and adapted behavioural determinants of skills, competence and autonomous motivation that must be established as part of the initiation of physical activity behaviour. An inventory of 8 determinants of engagement in long-term PA after cancer was developed. Clusters of BCTs are presented along with proposed MoA which can be tested using mediation analysis in future trials.
Understanding the processes of PA maintenance after cancer and presentation of implementable and testable intervention components and mechanisms of action to promote continued PA can inform future intervention development.
This resource can act as a starting point for selection of intervention components for those developing future interventions. This will facilitate effective support of individuals affected by cancer to maintain PA for the long term.
本文描述了维持身体活动（PA）的概念框架及其在未来干预设计中的应用。
系统文献回顾和对 27 名癌症患者的深入（N=27）定性访谈的证据用于开发长期身体活动行为的概念框架。列出了长期 PA 的决定因素，并将其与理论领域框架的领域联系起来，反过来又将其与相关的行为改变技术（BCT）联系起来，最后与提出的作用机制（MoA）联系起来。
概念框架在不可改变的背景因素（如人口统计学和物质资源）的背景下提出，并存在学习和适应技能、能力和自主动机的行为决定因素，这些因素必须作为身体活动行为开始的一部分来建立。制定了癌症后长期参与 PA 的 8 个决定因素清单。提出了一系列 BCT 以及建议的 MoA，可以在未来的试验中使用中介分析进行测试。
了解癌症后 PA 的维持过程，并提出可实施和可测试的干预组件和作用机制，以促进持续的 PA，可以为未来的干预发展提供信息。
本资源可用作开发未来干预措施的人员选择干预组件的起点。这将有助于有效地支持受癌症影响的个人长期保持 PA。
