Objective: To verify that motivational concepts tested in other educat
ional settings are relevant to understanding medical students' choice
of a career in internal medicine. More specifically, to compare the ef
fects of ''facilitating students' interest'' versus ''controlling stud
ents' learning'' as educational models during the internal medicine cl
erkship. Design: An observational retrospective study of 89 fourth-yea
r medical students. Structural equation modeling compared the two mode
ls statistically. Main outcome measure: Student choice of internal med
icine residency. Results: Instructors who supported students' autonomy
engendered in students greater feelings of competence and interest in
internal medicine than did controlling instructors. Perceived compete
nce further enhanced students' interest in internal medicine. In turn,
interest predicted students' choosing an internal medicine residency.
Overall, the facilitating students' interest model better explained s
tudents' choice of internal medicine than did the controlling students
' learning model. Conclusions: The results verify that the nature of t
he learning climate during the internal medicine clerkship is an impor
tant predictor of students' subsequent pursuit of internal medicine tr
aining. Instructors who teach in an autonomy-supportive manner enhance
students' perceived competence and interest in internal medicine, whi
ch increases the likelihood they will select an internal medicine resi
dency.
