This document summarizes a study that examined whether occupational therapists' attitudes toward professionalism vary by generational cohort. The study administered a professionalism questionnaire to occupational therapists from four generations: Silent, Boomer, Gen X, and Millennial. Results found that Millennials had lower scores than other cohorts in several areas related to duty, honor, and integrity. While all cohorts recognized the importance of appropriate client relationships, cohorts scored lower on providing and receiving feedback. The study concludes with recommendations to increase emphasis on professionalism, self-reflection, and feedback across generations in occupational therapy education and practice.
