The Health Student Academic Locus of Control Scale is a 20-item context-specific scale, developed to measure Internal and External control beliefs of students in courses allied to medicine. Psychometric properties are acceptable (N = 164) so the scale can be used to measure control beliefs in a longitudinal study.
