Head nurses' performance plays an important role in the successful operation of hospitals. Identification and prioritisation of managerial competencies required for these supervisors and evaluation of their performance on this basis are necessary. This study aimed to provide a valid tool for assessing managerial competencies of hospital department head nurses. First, through literature review, Delphi technique and expert panel, a competency model was developed. Then using the analytic hierarchy process, competencies were weighted and prioritised. Finally, based on the model, an instrument was designed to measure the competencies of head nurses. Validity and reliability of the instrument was also checked. The proposed framework included 27 competencies categorised by four main managerial tasks: planning, organising, leadership and control. Findings revealed that the highest priority was given to strategic thinking (0.1221) and the lowest priority was given to evidence-based decision making (0.007). Based on impact score and content validity ratio results, the content validity of all questions has been proved. Furthermore through the use of a content validity index, 11 questions were omitted or modified. The study presents a valid and comprehensive model for assessing managerial competencies of hospital department head nurses in order to take an important step towards improving their performance.
