The present study aimed to develop a competency framework for interprofessional collaboration in an occupational health team. This study was carried out in three stages. In the first stage, the viewpoints of different stakeholders on the essential competencies of interprofessional team members in occupational health services (OHS) were assessed. In the second stage, extracted codes were converted into competencies in expert panels. After that, the extracted items were categorized by inductive content analysis approach into competency framework. In the third stage, the content validity of interprofessional competencies in OHS was evaluated. The competency framework was finalized in six competency domains including prevention, occupational disease management, occupational health assessments, inter-disciplinary and interprofessional collaboration, education, and evidence-based practice and professionalism. The framework could be developed in interprofessional education in OHS based on competency-based education approach.
