BACKGROUND The Theory of Planned Behaviour (TPB) has been proposed as an appropriate model for creating a theory-driven approach to teaching medical professionalism. However, there is a lack of empirical evidence into its efficacy. This study explores if the TPB can assess UK medical doctors' professional behaviours and explores if there are differences in the TPB's efficacy depending on doctors' primary medical qualification (UK or outside). METHODS Three hundred fourteen doctors in England at 21 NHS Trusts completed a questionnaire about reflective practice, using the General Medical Council's confidentiality guidance, and raising a patient safety concern. The majority of participants were male (52%), white (68%), consultants (62%), and UK medical graduates (UKGs) (71%). RESULTS The TPB variables of attitudes, subjective norms, and perceived behavioural control were predictive of intention to engage in raising concerns (R2 = 35%), reflection (R2 = 52%), and use of confidentiality guidance (R2 = 45%). Perceived behavioural control was the strongest predictor of intentions to raise a concern (β = 0.44), while attitude was the strongest predictor of intentions to engage in reflective practice (β = 0.61) and using confidentiality guidance (β = 0.38). The TBP constructs predicted intention for raising concerns and reflecting for both UKGs and non-UKGs (Fs ≥ 2.3; ps ≤ .023, βs ≥ 0.12). However, only perceived behaviour control was predictive of intentions to use guidance for both UKGs and non-UKGs (β = 0.24) while attitudes and norms were just predictive for UKGs (βs ≥ 0.26). CONCLUSIONS This study demonstrates the efficacy of the TPB for three professional behaviours. The implications for medical educators are to use the variables of the TPB (attitudes, subjective norms, and perceived behavioural control) in the education of professionalism, and for medical education researchers to further our understanding by employing the TPB in more empirical studies of non-clinical behaviours.

基于理论的医生从事职业行为意图研究。

背景技术已经提出了计划行为理论（TPB）作为创建理论驱动的医学专业教学方法的合适模型。但是，缺乏有效性的经验证据。这项研究探讨了TPB是否可以评估英国医生的专业行为，并探讨了根据医生的基本医疗资格（英国或外界），TPB的疗效是否存在差异。方法英国21个NHS Trusts的314位医生使用总医务委员会的保密指南填写了一份关于反思性实践的调查表，并提出了对患者安全的担忧。大部分参与者为男性（52％），白人（68％），顾问（62％）和英国医学毕业生（UKGs）（71％）。结果态度，主观规范，行为控制和感知行为控制可预测是否会引起关注（R2 = 35％），反思（R2 = 52％）和使用保密指导（R2 = 45％）。知觉的行为控制是提出关注的意图的最强预测因子（β= 0.44），而态度是进行反思性实践（β= 0.61）和使用保密指导的最强预测因子（β= 0.38）。TBP构造了对UKG和非UKG引起关注和反映的预期意图（Fs≥2.3； ps≤.023，βs≥0.12）。然而，只有知觉的行为控制可以预测使用UKG和非UKG的指南的意愿（β= 0.24），而态度和规范仅可以预测UKG（β≥0.26）。结论本研究证明了TPB对三种专业行为的疗效。
