Objective: 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. Method: 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. Results: 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. Conclusion: the instrument is pioneering and accessible for the Brazilian context, with potential to identify barriers and facilitators self-harm prevention.
