Similarly, it will be important to explore further the interplay between psychosocial factors that may contribute to sexual risk and reported unprotected acts to develop effective, targeted prevention campaigns. Here, we found that differences in the risk patterns between bisexually- and gay-identified men were not explained by lower levels of gay community attachment or social support in sexual matters. It is possible that other psychosocial factors may underlie such differences, but were not assessed in this study. It is also possible that the personal meanings and behavioral implications of gay community attachment or social support in sexual matters were not adequately captured with the close-ended items administered during our brief street survey.
