Even though a few studies have been conducted, the result is inconsistent between studies. The Theory of Planned Behavior (TPB) is a widely used framework for predicting and understanding health behaviors. In the study area, the theory of planned behavior ability to predict breast self-examination among women was not done before. Therefore, this study aimed to determine the efficacy of the Theory of Planned Behavior to predict breast self-examination among women.
This study used a systematic review and meta-analysis of studies conducted from 2008 to 2018 globally. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. PubMed, Semantic Scholar, Hinari, and Google Scholar electronic databases were searched. The analysis was performed using STATA 17 software. Heterogeneity and publication bias were assessed using forest plots, I Cochran's Q statistics, Funnel plots, and the Egger test respectively. Pooled analysis was conducted using the random-effects model of the DerSimonian-Laird method.
A total of 5 articles were included in this systematic review and meta-analysis. The overall Pooled Proportion of variance of the Theory of Planned Behavior ability to predict breast self-examination among women was explained at 38% (95%CI: 26.9, 49.1).
The overall Pooled Proportion of variance explained by the Theory of Planned Behavior ability to predict breast self-examination among women was low as compared to the original assumption of variance explained. While the Theory of Planned Behavior provides a useful framework for understanding health behaviors, it may not fully capture all the complex factors contributing to breast self-examination. Additionally, future studies should consider using alternative measures of variance explained to provide a more comprehensive understanding of the predictive power of the theory of planned behavior.
尽管已经开展了一些研究，但各研究结果并不一致。计划行为理论（TPB）是一个广泛用于预测和理解健康行为的框架。在该研究领域，之前尚未对计划行为理论预测女性乳房自我检查的能力进行过研究。因此，本研究旨在确定计划行为理论预测女性乳房自我检查的有效性。
本研究对2008年至2018年全球范围内开展的研究进行了系统评价和荟萃分析。遵循系统评价和荟萃分析的首选报告项目（PRISMA）指南。检索了PubMed、语义学者、Hinari和谷歌学术电子数据库。使用STATA 17软件进行分析。分别使用森林图、 Cochr an Q统计量、漏斗图和Egger检验评估异质性和发表偏倚。采用DerSimonian-Laird方法的随机效应模型进行合并分析。
本系统评价和荟萃分析共纳入5篇文章。计划行为理论预测女性乳房自我检查能力的总体合并方差比例为38%（95%CI：26.9，49.1）。
与最初假设的可解释方差相比，计划行为理论预测女性乳房自我检查能力的总体合并可解释方差比例较低。虽然计划行为理论为理解健康行为提供了一个有用的框架，但它可能无法完全捕捉到所有导致乳房自我检查的复杂因素。此外，未来的研究应考虑使用其他可解释方差的测量方法，以更全面地理解计划行为理论的预测能力。
