“…For example, a substantial part of the research concerning HIV and STIs and sexually related uses of the Internet has focused on gay men who meet offline sex partners online (e.g., Bolding, Davis, Hart, Sherr, & Elford, 2005;Bowen, Williams, & Horvath, 2004;Bull, McFarlane, Lloyd, & Rietmeijer, 2004;Elford, Bolding, & Sherr, 2001;Hospers, Kok, Harterink, & de Zwart, 2005;McFarlane, Ross, & Elford, 2004;Tikkanen & Ross, 2000. The rationale for conducting these studies has partly been to investigate how the Internet can be used by health professionals for intervention and preventive actions (e.g., Bolding et al, 2005;Hospers, Harterink, Van Den Hoek, & Veenstra, 2002;Kalichman, Benotsch, Weinhardt, Austin, & Luke, 2002;Keller, Labelle, Karimi, & Gupta, 2004;Klausner, Levine, & Kent, 2004;Levine & Klausner, 2005).…”
