Development and Evaluation of Two Abbreviated Questionnaires for Mentoring and Research Self-Efficacy

Objectives: To reduce respondent burden for future evaluations of the National Heart, Lung, and Blood Institute-supported Programs to Increase Diversity Among Indi­viduals Engaged in Health-Related Research (PRIDE), a mentored-research education program, we sought to shorten the 33-item Ragins and McFarlin Mentor Role Instru­ment (RMMRI), measuring mentor-role ap­praisals, and the 69-item Clinical Research Appraisal Inventory (CRAI), measuring research self-efficacy. Methods: Three nationally recruited, junior-faculty cohorts attended two, annual 2-3 week Summer Institutes (SI-1/SI-2: 2011/2012, 2012/2013, 2013/2014) at one of six PRIDE sites. Mentees completed the RMMRI two months after mentor assign­ment and the CRAI at baseline (pre-SI-1) and 6-month (mid-year) and 12-month (post-SI-2) follow-up. Publications data ob­tained from Scopus in October 2015 were verified with mentees’ curriculum vitae. The RMMRI and CRAI were shortened using an iterative process of principal-components analysis. The shortened measures were ex­amined in association with each other (mul­tiple linear regression) and with increase in publications (repeated-measures analysis of covariance). Results: PRIDE enrolled 152 mentees (70% women; 60% Black, 35% Hispanic/Latino). Cronbach’s alphas for the new 9-item RMMRI, 19-item CRAI, and four CRAI-19 subscales were excellent. Controlling for baseline self-efficacy and cohort, RMMRI-9 scores were independently, positively associated with post-SI-2 scores on the CRAI-19 and three subscales (writing, study design/data analysis, and collaboration/grant preparation). Controlling for cohort, higher RMMRI-9 and post-SI-2 CRAI-19 scores were each associated with greater increase in publications. Conclusions: The RMMRI-9 and CRAI- 19 retained the excellent psychometric properties of the longer measures. Find­ings support use of the shortened mea­sures in future evaluations of PRIDE.
