Technical clinical procedures constitute an important part of the work
of general practitioners. Assessment of competence in the relevant sk
ills is important from the perspective of quality assurance. In this s
tudy, the psychometric characteristics of three different methods for
assessment of competence in technical clinical skills in general pract
ice were evaluated. A performance-based test (8 stations), a written k
nowledge test of skills (125 items) and a self-assessment questionnair
e (41 items) on technical clinical skills were administered to 49 GPs
and 47 trainees in general practice. The mean scores on the performanc
e-based test and the written knowledge test of skills showed no substa
ntial differences between GPs and trainees, whereas the GPs scored hig
her on the self-assessment questionnaire. While the correlation of the
score on the knowledge test of skills with the store on the performan
ce-based test was moderately high, the score on the self-assessment qu
estionnaire showed a rather low correlation with the performance-based
test. Although performance-based testing is obviously the best method
to assess proficiency in hands-on skills, a written test can serve as
a reasonable alternative, particularly for screening and research pur
poses.
