Sexual minority group members are at a higher risk for mental health difficulties than are heterosexual individuals. The results of this study showed that college student sexual minorities were common in counseling centers and that they were more likely than heterosexual students to seek counseling. The results also showed that sexual orientation groups differed in meaningful ways from one another, and many sexual orientation groups reported higher levels of psychological symptoms than did heterosexual students.
