A Longitudinal Assessment of Self-directed Learning Readiness and Development in Medical Students

Self-directed learning (SDL) competency is important for physicians to stay abreast of advances in their field and to provide the best available evidence-based care to their patients. Therefore, an essential responsibility of medical educators is to ensure the development of SDL skills in their students. The first objective of this study was to investigate longitudinally the degree to which medical students were ready to engage in SDL. The second objective was to examine students' perceptions of their SDL development throughout training.

A 2-part study of preclinical and clinical medical students was carried out at a midwestern U.S. university. In Study A, a longitudinal assessment of preclinical medical students' readiness to engage in SDL was conducted by administering an SDL readiness survey (SDLRS). In Study B, third- and fourth-year medical students were asked to reflect on their SDL development, in addition to completing the SDLRS.

After validating the Hendry and Ginns version of the SDLRS in preclinical medical students during Study A, we found that 3 of the 4 subscales remained constant over the 3 iterations of the survey while the self-determination subscale increased significantly between the first and third iteration of the survey. In Study B, an analysis of the clinical medical students' comments indicated a perceived increase in their SDL abilities and a growing appreciation of SDL. However, the SDLRS scores of clinical students did not differ from the results observed in preclinical students in Study A.

The results of the SDLRS indicated that the experience of students in our medical school has a positive influence on self-determination by the end of the preclinical years. Furthermore, analysis of the reflections of clinical students indicated ongoing development of SDL skills throughout their medical school training that were influenced by a wide range of experiences.
