背景：为了改善医疗保健环境中创新的实施，了解影响医疗保健专业人员行为的因素非常重要。我们的目标是开发一份英语和荷兰语的通用问卷，评估修订后的 TDF（Cane 等人，2012）中行为决定因素的 14 个领域，该问卷可以根据不同的目标、行动、背景和兴趣时间进行定制，并调查问卷项目的判别性内容有效性。方法：我们确定了现有的调查问卷，包括评估 TDF 领域内结构的项目，并在需要时开发新项目。 19 名评委将 79 个项目分配给一个或多个 TDF 域。使用单样本 t 检验来检查每个项目的判别内容有效性，即项目是否测量预期领域或项目是否测量领域组合。 结果：我们确定了被判断为区分测量 14 个领域中的 11 个领域的项目。衡量强化、目标和行为调节领域的项目被判断为衡量领域的组合。结论：我们开发了英语和荷兰语的调查问卷，能够有区别地评估大多数 TDF 领域。结果部分支持 Cane 等人 (2012) 对 TDF 的 14 域验证，并表明 Michie 等人 (2005) 12 域原始版本可能更适用于开发基于 TDF 的调查问卷。确定的项目为开发调查问卷提供了坚实的基础，以衡量基于 TDF 的医疗保健专业人员实施行为的决定因素，以适应不同的目标、行动、环境和时间。未来的研究应该调查此类问卷在实践中的并发和预测有效性和可靠性。
Background: To improve the implementation of innovations in healthcare settings, it is important to understand factors influencing healthcare professionals' behaviors. We aimed to develop a generic questionnaire in English and in Dutch assessing the 14 domains of behavioral determinants from the revised TDF (Cane et al., 2012) that can be tailored to suit different targets, actions, contexts, and times of interest, and to investigate questionnaire items' discriminant content validity.Methods: We identified existing questionnaires including items assessing constructs within TDF domains and developed new items where needed. Nineteen judges allocated 79 items to one or more TDF domains. One-sample t-tests were used to examine the discriminant content validity of each item, i.e., whether items measured intended domains or whether items measured a combination of domains.Results: We identified items judged to discriminately measure 11 out of 14 domains. Items measuring the domains Reinforcement, Goals, and Behavioral regulation were judged to measure a combination of domains.Conclusions: We have developed a questionnaire in English and in Dutch able to discriminately assess the majority of TDF domains. The results partly support Cane et al.'s (2012) 14-domain validation of the TDF and suggest that Michie et al.'s (2005) 12-domain original version might be more applicable in developing a TDF-based questionnaire. The identified items provide a robust basis for developing a questionnaire to measure TDF-based determinants of healthcare professionals' implementation behaviors to suit different targets, actions, contexts, and times. Future research should investigate the concurrent and predictive validity and reliability of such a questionnaire in practice.
