background To evaluate the quality of the supervision of residents, questionnaires are frequently used.
aim Changes in resident ratings were assessed using the validated Evaluation and Feedback for Effective Clinical Teaching (effect) questionnaire.
method Supervisors (n=89) of nine medical specialities were evaluated using a validated instrument (effect). Mean overall scores (mos) and mean scale scores were compared using paired t-tests. Ten supervisors were interviewed to determine factors that stimulate or hinder improvement after an evaluation.
results The strongest increase was seen in supervisors with an mos <4.0. Motivation to improve and dialogue about the feedback stimulated improvement. Lack of time and support hindered improvement.
conclusion Evaluating supervisors by providing feedback and a dialogue is suitable to improve their supervision of residents.
