Throughout the years, leaders in the profession have challenged us to affirm the value of occupational therapy and to substantiate what we do. Occupational therapy practitioners have always focused on what most matters to clients in what is now called client-centered or patient-centered practice. We have also focused on client function to enable participation in everyday life. In a welcome shift, society’s views about health and meaning-making are becoming more congruent with the long-standing ideals of occupational therapy. Now, more than ever, we have a powerful opportunity to communicate our competence. But how do we assert our competence and the complexity of occupation with confidence? This lecture draws on the conceptual foundations of theories about competence and confidence and provides examples from the research literature, and a practitioner and client narrative to illustrate the factors that enable us to effectively demonstrate the value of occupational therapy.
