The responses “never”, “mostly not” and “sometimes” have been categorized as getting condomless anal sex, whereas “mostly” and “always” had been categorized as utilizing 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 were conducted to investigate the association among variety of internet site and norms. For the type of web site variable, sex venue was selected as the reference category. Primarily based on a prior study (Grov, 202), the multivariate model included variables that have been considered potential confounders for the association between type of web-site and norms: age, education level, nationality, and sexual orientation. For MSM who reported each the assumed behavior and their very own actual behavior (n262), we compared the scores on the norms variables employing McNemar tests. In addition, univariate and multivariate logistic regression analyses have been conducted to investigate the association between norms and one’s personal condom use. All norm variables had been entered as continuous in to the model. For these analyses, two multivariate models had been constructed. Model examined the associations in between norms with regards to other guests and one’s own condom use. Model two examined the associations involving norms regarding the excellent pal and own condom use, controlling for norms with regards to other guests. Both models had been adjusted for variables that had been considered prospective confounders for the association between norms and personal condom use (i.e age, education level, nationality, sexual orientation) as recommended within the literature (e.g (Ghaziani Cook, 2005)). For all analyses, we checked for interactions involving the main variables of interest plus the other variables in the final multivariate models. Prior PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/25870032 to the logistic regression analyses, collinearity amongst all variables was checked by computing variance inflating factor (VIF) for each and every determinant and by computing correlations among the determinants. VIF values above 0 and correlations above 0.70 had been regarded as an indication of collinearity. For all analyses, a p 0.05 was regarded statistically important. Analyses were performed with all 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 internet sites: 376 participants at eight sex venues, 537 participants at two barsclubs, 3 participants at 9 socialsports gathering venues, 495 participants at 6 dating websites and 855 participants at two social network sites.
