Purpose This study aimed to develop a questionnaire measuring preventive behaviors at work. Methods A three-step design, including qualitative and quantitative methods, was followed: (1) item generation, (2) experts’ validation of content, and (3) pretesting. Results For step 1, 49 relevant existing scales were reviewed, and a pool of 172 items was generated. Redundant items were deleted (n = 48), and unclear items were reworded (n = 27). For step 2, 14 experts (five occupational therapists, four researchers, and five workers) assessed the representativeness, relevance, and clarity of each item through content validity indices (CVIs). An average overall CVI of 0.97 was obtained, and 87.5% of the experts stated that the questionnaire was comprehensive. During this step, 63 items were deleted, and 35 were modified. For step 3, the tool was pretested in the clinical settings of four dyads (occupational therapist–worker). The thematic analysis of interview content allowed several changes to be made to the questionnaire, including the addition of information and format changes. Conclusions Overall, this three-step study led to the construction of a 61-item French questionnaire entitled the Échelle de fréquence des comportements préventifs au travail [Frequency Scale of Preventive Behaviors at Work]. In rehabilitation settings, this tool could be useful to support professionals in enabling workers to adopt preventive behaviors, thereby fostering a healthy, sustainable return to work after a disability period. However, further metrological property assessment is required. A validating study using a large pool of workers is ongoing.

目的本研究旨在开发一份测量工作中预防行为的问卷。方法遵循三步设计，包括定性和定量方法：(1) 项目生成，(2) 专家对内容的验证，以及(3) 预测试。结果对于步骤 1，审查了 49 个相关的现有量表，并生成了 172 个项目的库。删除多余的项目（n = 48），并重新措辞不明确的项目（n = 27）。对于第 2 步，14 位专家（5 名职业治疗师、4 名研究人员和 5 名工作人员）通过内容有效性指数 (CVI) 评估了每个项目的代表性、相关性和清晰度。获得的平均总体 CVI 为 0.97，87.5% 的专家表示问卷是全面的。在此步骤中，删除了 63 项，修改了 35 项。对于第 3 步，该工具在四个二人组（职业治疗师 - 工作者）的临床环境中进行了预先测试。访谈内容的主题分析允许对问卷进行若干更改，包括添加信息和更改格式。结论总体而言，这项三步研究导致构建了一份 61 项法语问卷，题为Échelle de fréquence des comportements préventifs au travail [工作中预防行为的频率量表]。在康复环境中，该工具可用于支持专业人员使工人能够采取预防行为，从而促进在残疾期后健康、可持续地重返工作岗位。然而，需要进一步的计量特性评估。一项使用大量工人的验证研究正在进行中。
