Health behaviour can change outcomes in both healthy and unhealthy populations and are particularly useful in promoting compliance to treatment and maintaining fidelity to care seeking and follow-up options in chronic diseases. Interventions to change health behaviour based on psychological theory are more often successful than those without any underlying theory. The theory of planned behaviour (TPB) is one such psychological theory which had been found to predict human behaviour with respect to disease prevention and when applied to interventions can change the outcomes of diseases. Most of the research evidence of TPB-based interventions have been from developed world. Evidence is required whether TPB-based interventions can be applied and works in low-resource, low health-literacy settings of low- and middle-income countries (LMICs).
The protocol has been developed as per PRISMA-P guidelines and incorporates PICO (population, intervention, comparison, outcomes) framework for describing the methodology. Population above 18 years of age and having any chronic disease (as defined for this systematic review) will be selected, while any health or educational intervention based on constructs of TPB will be included. Comparison will be with non-TPB-based interventions or treatment as usual without any intervention, and the primary outcome will be the behaviour change effected by the TPB-based intervention. Intervention studies will be considered, and relevant databases like MEDLINE, Embase, Cochrane Library and ProQuest will be explored. Data extraction will done in a standardised form, and risk-of-bias assessment will be done using the Cochrane Collaboration's tools for such assessment. Narrative synthesis of the selected studies will be done to draw the conclusions, and meta-analysis will be done to calculate the effect estimates with I-squared statistics to describe the heterogeneity.
This systematic review will provide new evidence on fidelity and effectiveness of the TPB-based interventions among chronic disease patients from low health literacy, resource-poor background. It will inform of how to plan and use such interventions to change health behaviour in chronic disease patients, particularly in LMIC settings.

健康行为可以改变健康人群和不健康人群的结局，在促进治疗依从性和维持慢性病寻求和随访选择的忠实性方面特别有用。基于心理理论的健康行为干预比没有任何潜在理论的干预更成功。计划行为理论（TPB）就是这样一种心理理论，它被发现可以预测人类在疾病预防方面的行为，并且当应用于干预时，可以改变疾病的结局。基于 TPB 的干预措施的大多数研究证据都来自发达国家。需要有证据表明，基于 TPB 的干预措施是否可以在资源匮乏、健康素养低、中低收入国家（LMICs）的低资源、低健康素养环境中应用和发挥作用。
该方案是根据 PRISMA-P 指南制定的，并纳入了 PICO（人群、干预、比较、结局）框架来描述方法。将选择年龄在 18 岁以上且患有任何慢性病（为本系统评价定义）的人群，同时纳入基于 TPB 结构的任何健康或教育干预措施。将与非 TPB 为基础的干预措施或不进行任何干预的常规治疗进行比较，主要结局是 TPB 为基础的干预措施所产生的行为改变。将考虑干预研究，并探索相关数据库，如 MEDLINE、Embase、Cochrane 图书馆和 ProQuest。将以标准化表格形式提取数据，并使用 Cochrane 协作工具进行风险偏倚评估。将对选定的研究进行叙述性综合，以得出结论，并进行荟萃分析，以计算效应估计值，并用 I 平方统计量描述异质性。
本系统评价将提供新的证据，证明低健康素养、资源匮乏背景下的慢性病患者基于 TPB 的干预措施的忠实性和有效性。它将说明如何在慢性病患者中计划和使用这种干预措施来改变健康行为，特别是在 LMIC 环境中。
