The inability to produce sustainable lifestyle modifications (e.g., physical activity, healthy diet) remains a major barrier to reducing morbidity and mortality from prevalent, preventable conditions. The objective of this paper is to present a model that builds on and extends foundational theory and research to suggest novel approaches that may help to produce lasting behaviour change. The model aims to integrate factors not typically examined together in order to elucidate potential processes underlying a shift from behaviour initiation to long-term maintenance. The central premise of the Maintain IT model builds on approaches demonstrating that in-tact executive function (EF) is critical for health behaviour initiation, for more complex behaviours beyond initiation, and in unsupportive environments and circumstances, but successful recruitment of EF is effortful and prone to error. Enduring changes are more likely if the underlying cognitive processes can become less effortful (non-conscious, automatic). The Maintain IT model posits that a centred identity transformation is one path leading to less effortful processing and facilitating successful recruitment of EF when necessary over the long term, increasing the sustainability of health behaviour change. A conceptual overview of the literature supporting the utility of this integrative model, future directions, and anticipated challenges are presented.

利用以身份为中心的身份转换，以减少执行人员的功能负担，以维护健康行为的变化：维护IT模型

无法产生可持续的生活方式改变（例如，体育锻炼，健康饮食）仍然是降低普遍存在的可预防疾病的发病率和死亡率的主要障碍。本文的目的是提供一个建立在基础理论和研究基础之上并对其进行扩展的模型，以提出可能有助于产生持久行为变化的新颖方法。该模型旨在整合通常未一起检查的因素，以阐明潜在的流程，这些流程是从行为发起到长期维护的基础。维护IT模型的中心前提是基于证明完好无损的执行职能的方法（EF）对于启动健康行为，对于超出启动行为的更复杂行为以及在无支持的环境和情况下都是至关重要的，但是成功募集EF费力且容易出错。如果潜在的认知过程变得不那么费力（无意识，自动），则持久的变化更有可能发生。维护IT模型认为，集中身份转换是一种导致省力处理的途径，并且在长期需要时有利于成功招募EF，从而提高了健康行为改变的可持续性。介绍了支持这种集成模型的实用性的文献的概念概述，未来的方向以及预期的挑战。
