Quality Assessment of TPB-Based Questionnaires: A Systematic Review

ObjectiveThis review is aimed at assessing the quality of questionnaires and their development process based on the theory of planned behavior (TPB) change model.MethodsA systematic literature search for studies with the primary aim of TPB-based questionnaire development was conducted in relevant databases between 2002 and 2012 using selected search terms. Ten of 1,034 screened abstracts met the inclusion criteria and were assessed for methodological quality using two different appraisal tools: one for the overall methodological quality of each study and the other developed for the appraisal of the questionnaire content and development process. Both appraisal tools consisted of items regarding the likelihood of bias in each study and were eventually combined to give the overall quality score for each included study.Results8 of the 10 included studies showed low risk of bias in the overall quality assessment of each study, while 9 of the studies were of high quality based on the quality appraisal of questionnaire content and development process.ConclusionQuality appraisal of the questionnaires in the 10 reviewed studies was successfully conducted, highlighting the top problem areas (including: sample size estimation; inclusion of direct and indirect measures; and inclusion of questions on demographics) in the development of TPB-based questionnaires and the need for researchers to provide a more detailed account of their development process.研究目的：本综述旨在基于计划行为理论（Theory of Planned Behavior, TPB）改变模型，评估调查问卷及其开发流程的质量。 研究方法：本研究于2002年至2012年间，在相关数据库中以选定的检索词开展系统性文献检索，筛选以开发基于计划行为理论的调查问卷为核心目标的相关研究。本次检索共筛查得到1034篇摘要，其中10篇符合纳入标准；随后采用两种不同的质量评价工具对其方法学质量进行评估：其一用于评价每项研究的整体方法学质量，其二则专为评估调查问卷内容与开发流程而设计。两款评价工具均包含与各项研究偏倚风险相关的条目，最终将二者结合，为每篇纳入研究计算整体质量得分。 研究结果：10项纳入研究中，8项在整体方法学质量评估中显示出较低的偏倚风险；而基于调查问卷内容与开发流程的质量评价结果显示，其中9项研究质量较高。 研究结论：本综述成功完成了10项纳入研究中调查问卷的质量评价工作，明确了基于计划行为理论的调查问卷开发过程中存在的核心问题领域，包括样本量估算、直接与间接测量条目纳入、人口统计学相关问题设置，并指出研究人员需更详细地阐述其问卷开发流程。
