The development of an appraisal questionnaire which measures junior doctors' opinions about their hospital experiences is described. The first section of the questionnaire consists of seven reliable subscales which measure opinions about teaching and learning, registrar teaching, consultant teaching, staff support, workload, administration and overall experiences during a period of attachment or term. The second part of the survey contains 11 reliable questions about the hours spent on service and education during the term. The responses to this measure of 257 randomly selected Australian junior doctors are described. The questionnaire may be used to contrast the experiences of junior doctors in different types of terms, different hospitals or varying levels of training. The data generated from the instrument can provide useful information about hospitals, such as the work practices of junior staff and the effectiveness of educational programs.
