Participants were asked how often they tested for HIV as described below, from which we calculated a measure of testing frequency indicative of annual and more frequent HIV testing. In the Glasgow/Edinburgh and London surveys, the number of HIV tests in the last 2 years was categorized into fewer than two, two or three and at least four tests. Testing regularity was sought in the Scotland‐wide online survey, so men who indicated that they tested “every 3/6 months” were categorized as having at least four tests, and those indicating testing “every year/every few years” were categorized as having had two or three tests; those remaining were categorized as having fewer than two tests. The latter category includes men who had never tested (who were a small proportion of the overall sample).
