Introduction: This paper describes the design (of process and content), implementation and evaluation of a component of the Human Diversity Module developed to teach cultural diversity to undergraduate medical students. The objectives of the teaching were to enable students to gain factual and practical information about other cultures and also for them to examine their own attitudes.

Method: Students completed a questionnaire, designed in a previous study, at two stages; the first before the component on cultural diversity had been delivered and the second after the sessions on cultural diversity. The time interval between stages 1 and 2 was 1 week. The cultural diversity component was developed using a range of sources.

Results: Out of 181 students, 140 (77ยท3%) completed the questionnaire at both stages. There were a number of statistically significant findings, which indicate that the teaching enabled the session objectives to be successfully met. The findings include statistically significant changes that reflect more ‘positive’ attitudes about cultures coming together and about specific cultures.

Conclusion: The study indicates that attitudes changed over the period of teaching. There is, however, scope for further development of measures to enable attitudinal shifts to be evaluated.
