Objectives: To evaluate factors that predict HIV testing using the model of health care utilisation as its conceptual framework and to analyse some of the factors that encourage or inhibit seeking an HIV test in this population.

Method: A cross sectional questionnaire study in two Genito-Urinary Medicine (GUM) clinics in central Scotland. A final sample of 195 represented a 91% response rate. Participants were categorised by their HIV testing status (already tested, planning to be tested, no intention to seek testing).

Results: The ‘already tested’ and ‘planning to be tested’ groups were combined as there were no significant differences on reported risk behaviours. Analysis therefore compared two groups those ‘testing’ (n = 66) and ‘not testing’ (n = 129). 67% of those not tested for HIV reported at least one HIV risk factor. Perceived risk was the strongest predictor of HIV testing using our model. Perception of risk and actual risk were not correlated. Those not seeking testing endorsed less benefits of testing and more denial of the need to be tested. Same day testing and testing without an appointment were endorsed as factors to promote testing.

Conclusion: To encourage people who have high risk factors to access HIV testing, programmes should: (1) highlight the benefits of testing which would be lost if people do not test, eg. effective drug treatments (2) increase the range of HIV testing services available (eg. same day testing). Furthermore, studies to determine the main predictors of perceived risk are needed if we are to increase testing in relevant populations.
