The responses “never”, “mostly not” and “sometimes” have been categorized as possessing condomless anal sex, whereas “mostly” and “always” had been categorized as applying condoms. The injunctive norm variable was dichotomized as follows: The responses “3” and greater had been categorized as disapproval of condom use, whereas the responses “” and “2” have been categorized as approval of condom use. Univariate and multivariate logistic regression analyses have been performed to investigate the association amongst kind of site and norms. For the kind of site variable, sex venue was chosen because the reference category. Based on a earlier study (Grov, 202), the multivariate model included variables that had been thought of possible confounders for the association among sort of web-site and norms: age, education level, nationality, and sexual orientation. For MSM who reported each the assumed behavior and their own actual behavior (n262), we compared the scores around the norms variables using McNemar tests. Furthermore, univariate and multivariate logistic regression analyses were performed to investigate the association among norms and one’s personal condom use. All norm variables were entered as continuous into the model. For these analyses, two multivariate models were constructed. Model examined the associations among norms concerning other guests and one’s own condom use. Model two examined the associations between norms concerning the great friend and personal condom use, controlling for norms with regards to other guests. Each models have been adjusted for variables that had been regarded possible confounders for the association in between norms and own condom use (i.e age, education level, nationality, sexual orientation) as suggested inside the literature (e.g (Ghaziani Cook, 2005)). For all analyses, we checked for interactions involving the principle variables of interest along with the other variables in the final multivariate models.

VIF values above 0 and correlations above 0.70 were regarded as an indication of collinearity. For all analyses, a p 0.05 was viewed as statistically important. Analyses were performed using the SPSS 9 statistical package (SPSS Inc Chicago, IL, USA).Author Manuscript Author Manuscript Author Manuscript ResultsEnrollmentA total of 2376 participants enrolled within the study at 56 web pages: 376 participants at eight sex venues, 537 participants at 2 barsclubs, three participants at 9 socialsports gathering venues, 495 participants at 6 dating internet sites and 855 participants at two social network sites. Sample qualities The median age on the participants was 30 years (IQR 2243), 56 have been highly educated, and 82 have been of Dutch background (Table ).
