The use of education alone as a technique to change behavior in interventions is usually insufficient, particularly in health interventions. Behavior change techniques have been shown to be effective in fostering positive changes in health behaviors such as diet and physical activity. The upskilling of health professionals can increase perceived capability and motivation toward eliciting change in clients' behaviors. However, to date, dietitians have received limited training in behavior change and have expressed a need for continuous professional development.
The study objectives are to (1) develop and evaluate the effectiveness and acceptability of two 2-hour behavior change workshops on changing dietitians behavior (ie, range of behavior change techniques used and frequency of use) across 3 time points; (2) determine if participation in these workshops will elicit changes in dietitians' perceived capability, opportunity, and motivation toward using behavior change techniques; and (3) determine the acceptability of the training and its application in practice by dietitians.
We will recruit registered dietitians (N=140) in Australia to participate in this randomized controlled trial. Participants will be randomly assigned to either the intervention or 3-month waitlist control condition and complete outcome measures at 3 time points: baseline, after the workshop, and follow-up at 3 months. Both groups will complete 2 workshops on behavior change that are guided by the COM-B (Capability, Opportunity, Motivation, and Behavior) Model and embedded with behavior change techniques. The primary outcome is changes in behavior, (ie, the range of behavior change techniques used and their frequency of use). Secondary outcomes include changes in perceived capability, opportunity, motivation, and preparedness as a health professional toward delivering behavior change techniques. The acceptability of the workshops will also be assessed after the workshop through the postworkshop survey and semistructured interviews. A series of 2-way repeated measures ANOVAs and regressions will be used. Qualitative data will be analyzed using thematic analysis.
Participant recruitment commenced in June 2023. The results of the study are expected to be published in November 2024. The results will allow us to assess comparisons between the intervention and waitlist control groups, as well as changes in perceived capability, opportunity, motivation, and preparedness over a 3-month period. It will also provide an understanding of the acceptability of the training as a form of continuous professional development for dietitians.
If found to be effective, the results of this 2-arm randomized controlled trial will guide future training and continuous professional development for health professionals in changing behavior in practice. Our findings will contribute to our understanding of the application of behavior change techniques in practice with clients and identify components of COM-B where dietitians may need future support.

仅将教育作为一种在干预措施中改变行为的技术通常是不够的，尤其是在健康干预方面。行为改变技术已被证明在促进饮食和体育活动等健康行为的积极改变方面是有效的。提升健康专业人员的技能可以增强他们促使客户行为改变的感知能力和动力。然而，迄今为止，营养师在行为改变方面接受的培训有限，并表示需要持续的专业发展。
本研究的目的是：（1）开发并评估两个为期2小时的行为改变工作坊在三个时间点对营养师行为改变（即所使用的行为改变技术范围和使用频率）的有效性和可接受性；（2）确定参加这些工作坊是否会引起营养师在使用行为改变技术方面的感知能力、机会和动力的变化；（3）确定培训的可接受性及其在营养师实践中的应用情况。
我们将招募澳大利亚的注册营养师（N = 140）参与这项随机对照试验。参与者将被随机分配到干预组或3个月的等待名单对照组，并在三个时间点完成结果测量：基线、工作坊后以及3个月后的随访。两组都将参加两个由COM - B（能力、机会、动力和行为）模型指导并融入行为改变技术的行为改变工作坊。主要结果是行为的变化（即所使用的行为改变技术范围及其使用频率）。次要结果包括作为健康专业人员在提供行为改变技术方面的感知能力、机会、动力和准备情况的变化。工作坊结束后，还将通过工作坊后调查和半结构化访谈评估工作坊的可接受性。将使用一系列双向重复测量方差分析和回归分析。定性数据将采用主题分析进行分析。
参与者招募于2023年6月开始。研究结果预计于2024年11月发表。这些结果将使我们能够评估干预组与等待名单对照组之间的比较，以及在3个月期间感知能力、机会、动力和准备情况的变化。它还将使我们了解该培训作为营养师持续专业发展形式的可接受性。
如果被证明有效，这项双臂随机对照试验的结果将指导未来针对健康专业人员在实践中改变行为的培训和持续专业发展。我们的研究结果将有助于我们理解行为改变技术在与客户实践中的应用，并确定COM - B模型中营养师未来可能需要支持的部分。
