Thus, a nonsignificant Brant test kinase inhibitor 17-AAG indicates that the model exhibits the same slope but allows the intercepts to vary across k?1 equations of the dependent variable categories (Long & Freese, 2006). If violation of the Brant test occurred or small cell sizes precluded calculation of Brant diagnostics, the categories of the dependent variable were collapsed to better fit the data, which ultimately resulted in a three-category dependent variable that fit nearly all the stratified models. Proportional odds ratios are reported with 95% CIs. Missing data analysis showed that, on all variables germane to the models, none were missing more than 5%, thus listwise deletion was used (Tabachnick & Fidell, 2007). All analyses were conducted using Stata/SE version 11.1 (Stata Corp, 2009).

Results The analytic sample tended to be female (62.1%) and non-Hispanic White (66.0%). The mean age was 20.1 years (SD = 1.6), recalling that the sample was truncated to only include those in the age range of young adulthood (i.e., 18�C24 years). Since a random 5% subsample of heterosexual individuals was used for this analysis, the percentages of sexual orientation groups were made more equivalent than the original dataset that included all heterosexual persons; however, they still comprised the largest percent (42%) within the analytic sample (see Table 1). Significantly more men than women identified as gay, while significantly more women than men identified as bisexual, a finding that is typical among studies using sexual identity measures of sexual orientation (Chandra, Mosher, Copen, & Sionean, 2011; Laumann, Gagnon, Michael, & Michaels, 1994).

Table 1. Demographic Characteristics, Smoking Status, and Victimization by Sexual Orientation Bivariate analyses revealed that, globally, among sexual orientation categories, significantly greater proportions of sexual minority individuals indicated experiences of victimization and discrimination when compared with their heterosexual counterparts (see Table 1). Of particular note is that more than 37% of gay/lesbian respondents indicated experiencing some form of discrimination in the past 12 months compared with approximately 4% of heterosexual respondents. Furthermore, gay/lesbian and bisexual respondents Batimastat differed on some stressors. For instance, gay/lesbian individuals reported significantly more discrimination than their bisexual peers (p < .01), and bisexual respondents reported significantly more fights and physical assault (p < .01, respectively) than gay/lesbian respondents. Table 1 also illustrates numerous differences in smoking.
