为了能够设计有效的策略，以改善医疗保健专业人员的实施行为，一个有效的和可靠的问卷调查，需要评估潜在的实施决定因素。本研究描述了实施行为决定因素问卷（DIBQ）的编制过程，并对该问卷的信度和效度进行了检验。开发DIBQ以测量TDF的12域版本的潜在行为决定因素（米吉等人，2005年）。我们确定了现有的问卷调查，包括项目评估结构内TDF域和开发新的项目，在需要的地方。实证因素分析被用来检查是否预定义的结构的基于TDF的问卷的数据支持。计算Cronbach’s alpha信度以评估问卷的内部一致性信度，并考察各领域的区分效度。我们开发了一个初始问卷，包含100个项目评估12个领域。从验证性因素分析和Cronbach的α得到的结果导致在最终的问卷包括93个项目评估18个领域，解释63.3%的方差，和内部一致性的可靠性值范围从0.68到0.93。领域表现出良好的判别效度，虽然领域的“知识”和“技能”和领域的“技能”和“社会/职业角色和身份”高度相关。我们已经开发了一个有效的和可靠的问卷，可用于评估医疗保健专业人员的实施行为的TDF的理论域的潜在决定因素。DIBQ可供研究人员和从业人员使用，他们有兴趣确定实施行为的决定因素，以便能够制定有效的策略来改善医疗保健专业人员的实施行为。此外，研究结果提供了一个新的TDF验证，并表明，域“环境背景和资源”可能被划分为几个环境相关的域。
To be able to design effective strategies to improve healthcare professionals’ implementation behaviors, a valid and reliable questionnaire is needed to assess potential implementation determinants. The present study describes the development of the Determinants of Implementation Behavior Questionnaire (DIBQ) and investigates the reliability and validity of this Theoretical Domains Framework (TDF)-based questionnaire. The DIBQ was developed to measure the potential behavioral determinants of the 12-domain version of the TDF (Michie et al., 2005). We identified existing questionnaires including items assessing constructs within TDF domains and developed new items where needed. Confirmatory factor analysis was used to examine whether the predefined structure of the TDF-based questionnaire was supported by the data. Cronbach’s alpha was calculated to assess internal consistency reliability of the questionnaire, and domains’ discriminant validity was investigated. We developed an initial questionnaire containing 100 items assessing 12 domains. Results obtained from confirmatory factor analysis and Cronbach’s alpha resulted in the final questionnaire consisting of 93 items assessing 18 domains, explaining 63.3% of the variance, and internal consistency reliability values ranging from .68 to .93. Domains demonstrated good discriminant validity, although the domains ‘Knowledge’ and ‘Skills’ and the domains ‘Skills’ and ‘Social/professional role and identity’ were highly correlated. We have developed a valid and reliable questionnaire that can be used to assess potential determinants of healthcare professional implementation behavior following the theoretical domains of the TDF. The DIBQ can be used by researchers and practitioners who are interested in identifying determinants of implementation behaviors in order to be able to develop effective strategies to improve healthcare professionals’ implementation behaviors. Furthermore, the findings provide a novel validation of the TDF and indicate that the domain ‘Environmental context and resources’ might be divided into several environment-related domains.
