Pour élaborer des stratégies d’intervention efficaces, il est important de comprendre les facteurs qui facilitent ou entravent l’adoption de comportements de sécurité spécifiques. Il n’existe actuellement aucun questionnaire permettant d’identifier les déterminants des comportements de sécurité pour les travailleurs dont la sécurité est essentielle. Cette étude fait état de l’élaboration et de la validation du Safety Behaviour Change Questionnaire (SBCQ) basé sur le Theoretical Domains Framework (TDF).

Understanding the factors that either facilitate or hinder the performance of specific safety behaviours is important in developing effective intervention strategies. A questionnaire to identify determinants of safety behaviours for safety–critical workers does not currently exist. This study reports the development and validation of the Safety Behaviour Change Questionnaire (SBCQ) based on the Theoretical Domains Framework (TDF). Following initial questionnaire development, a 3-stage testing procedure was adopted with three independent rail worker samples (totalling 620 participants), with a focus on three separate specific safety behaviours (removing slip/trip hazards, using PPE, safe tool storage). Exploratory factor analysis (EFA) was used for the identification of the underlying structure of the initial set of items. Confirmatory factor analysis (CFA) was undertaken to generate the model of best fit at the calibration and validation stages. The final version of the SBCQ consisted of 13 factors and 26 items. Subsequent analysis of psychometric invariance confirmed the stability of the model factor structure across three distinct research sub-samples. These initial results suggest that the SBCQ demonstrates reliable, stable and valid properties, and that it can be utilised by safety managers and practitioners to guide the design of safety interventions for a range of safety behaviours.
