to develop and validate an instrument based on the Theoretical Domains Framework (TDF) to identify barriers and facilitators perceived by health professionals in the prevention of self-harm. methodological study based on Pasquali's theoretical framework and the Theoretical Domains Framework. Face and content validations were performed through expert evaluation (n = 13) and construct validity, with health professionals (n = 91). Participants were selected by non-probabilistic convenience sampling. Data were collected on a virtual form and analyzed using the Content Validity Index (CVI), the First-Order Agreement (AC1) coefficient of concordance, and Horn's exploratory factor analysis. inter-rater agreement was considered moderate (AC1 = 0.52; SD = 0.04; 95% CI = 0.42 - 0.61; p = ≤ 0.005). After analysis with the target audience, three items were removed (KMO = < 0.6). Factor analysis identified three factors and 11 items, with the internal consistency of the instrument considered high (ω = 0.89). The final version was structured with 11 items on a Likert scale. the instrument is pioneering and accessible for the Brazilian context, with potential to identify barriers and facilitators self-harm prevention.
(1) The instrument identifies barriers and facilitators for the prevention of self-harm.
(2) The internal consistency of the instrument was considered high.
(3) The analysis identified the following factors: knowledge and capacity, context and institutional support.
(4) The instrument developed is easy to use and adaptable to different contexts in Brazil.
(5) The instrument contributes to studies on the prevention of self-harm.
基于理论领域框架（TDF）开发并验证一种工具，以识别卫生专业人员在预防自我伤害方面所感知到的障碍和促进因素。基于帕斯夸利理论框架和理论领域框架的方法学研究。通过专家评估（n = 13）进行了表面效度和内容效度验证，并对91名卫生专业人员进行了结构效度验证。参与者通过非概率便利抽样选取。数据通过虚拟表格收集，并使用内容效度指数（CVI）、一阶一致性（AC1）协调系数和霍恩探索性因素分析进行分析。评分者间一致性被认为中等（AC1 = 0.52；标准差 = 0.04；95%置信区间 = 0.42 - 0.61；p = ≤ 0.005）。在与目标受众进行分析后，删除了三个项目（KMO = < 0.6）。因素分析确定了三个因素和11个项目，该工具的内部一致性被认为较高（ω = 0.89）。最终版本由11个李克特量表项目构成。该工具在巴西背景下具有开创性且易于使用，有潜力识别预防自我伤害的障碍和促进因素。
（1）该工具识别预防自我伤害的障碍和促进因素。
（2）该工具的内部一致性被认为较高。
（3）分析确定了以下因素：知识与能力、背景与机构支持。
（4）所开发的工具易于使用且适用于巴西的不同背景。
（5）该工具有助于自我伤害预防研究。
