title: Psychometric properties of the mentor role instrument when used in an academic medicine setting.
abstract: The Ragins and McFarlin Mentor Role Instrument (RMMRI) was originally developed to measure perceptions of mentoring relationships in research and development organizations. The current study was designed to evaluate the RMMRI's reliability and validity when the instrument was administered to clinical and translational science trainees at an academic medical center. The 33-item RMMRI was administered prospectively to a cohort of 141 trainees at the University of Pittsburgh in 2007-2008. Likert-scale items focused on perceptions of five mentoring roles in the career dimension (sponsor, coach, protector, challenger, and promoter) and six mentoring roles in the psychosocial dimension (friend, social associate, parent, role model, counselor, and acceptor). Outcome items included overall perceptions of mentoring satisfaction and effectiveness. Of 141 trainees, 53% were male, 66% were white, 22% were Asian, and 59% were medical doctors. Mean age was 32 years. Analyses showed strong within-factor inter-item correlations (Pearson Coefficients of 0.57-0.93); strong internal consistency (Cronbach alphas of 0.82-0.97); confirmatory factorial validity, as demonstrated by confirmatory factor analysis of the two mentoring dimensions, 11 mentoring roles, and 33 RMMRI items; and concurrent validity, as demonstrated by strong correlations (Pearson Coefficients of 0.56-0.71) between mentoring dimensions, satisfaction, and effectiveness. This article concludes that the RMMRI shows reliability and validity in capturing the multidimensional nature of mentoring when administered to clinical and translational science trainees in the academic setting.
