The purpose of this study was to examine the relationship between job performance of wilderness and adventure therapy (WAT) field guides and personality traits. Specifically, this study utilized the NEO-PI-R to assess personality and the Field Guide Performance Evaluation (FGPE) to assess job performance. Job performance was measured by managers, peers, and WAT participants. The sample consisted of 89 personality assessments, gathered from both the U.S. and Canada. Ordinary least squares regression analysis indicated there was a non-significant relationship between field guide job performance and personality. Findings provide implications for WAT practitioners seeking the most qualified field guides possible.
