Background: A few studies have been done regarding the validity and reliability of the Mini-Peer Assessment Tool across various specialties. This study was conducted to determine the reliability, content and construct validity of Mini-Peer Assessment Tool to assess the competency of emergency medicine residents.
   Methods: This study was carried out to investigate the psychometric properties of the mini-PAT tool to evaluate the professional competencies of emergency medicine residents in educational hospitals affiliated to Tehran University of Medical Sciences. The initial Mini-Peer Assessment Tool was translated into Persian. After that, the content validity index and content validity ratio determined by consulting 12 professors of emergency medicine. The construct validity was determined with exploratory factor analysis and investigation of the correlation coefficient on 31 self and 248 peer assessment cases.
The reliability of the mini peer assessment tool was determined by internal consistency and item deletion by using Cronbach’s alpha coefficient. Reliability was also assessed by determining the agreement between the two tools of self-assessment and peer assessment by using the diagram Bland and Altman.
   Results: The results showed content validity ratio (CVR) of the items ranged from 0.56 to 0.83, and the content validity index (CVI) of the items ranged from 0.72 to 0.90. The reliability of the self-assessment and peer-assessment tools were 0.83 and 0.95 respectively and there was a relative agreement between the self-assessment method and the peer assessment method. Finally, the tool underwent exploratory factor analysis resulting extraction into two factors namely ‘clinical competencies’ and ‘human interactions’ in the peer assessment tool. In the self-assessment tool, the factors of ‘good practice’ and ‘technical competence’ were extracted.
  Conclusion: The results of the present study provided evidence of the adequacy of content validity, reliability of the contextually customized mini-peer assessment tool in assessing the competencies of emergency medicine residents.
