Clinical competence is generally defined as a combination of knowledge, skill and professional behaviour. It is typically assessed using written tests, direct observation, chart audit, client satisfaction surveys and supervisor ratings. This paper describes the development and evaluation of a chart-stimulated recall (CSR) measure that combines the methods of chart audit and clinician interview to assess the clinical competence of practicing occupational therapists. The CSR tool was developed using the Canadian Guidelines for Client-Centred Practice and taps global domains of competence: use of theory, assessment, program planning, intervention, discharge planning, follow-up, program evaluation, clinical reasoning and professional behaviours. This pilot study involved two independent raters/interviewers who assessed twelve occupational therapy clinicians on two occasions using a random sample of client cases/records on each occasion Results indicate that the CSR tool is not only reliable and valid, but also sufficiently generic to be used in a variety of practice settings as a global measure of on-the-job performance.
