As the press for services at university counseling centers increases, so does the need to provide optimal therapeutic services. Ethnic glossing in previous research has combined rather disaggregated the mental health treatment experiences of American Latinx (AL) students and International Latinx (IL) students. The purpose of this paper was to examine potential differences in (1) the number of attended sessions, (2) symptom severity, and (3) treatment improvement rates. We used a nationwide dataset including 13,156 AL students and 911 IL students. Results indicated that (1) there was no significant difference in attendance rates, (2) AL students had significantly worse initial symptom severity (d = 0.24), and (3) there were no significant differences in improvement rates. We discuss the importance of understanding the different clinical presentations of AL and IL students, as well as the importance of addressing ethnic glossing in future research and clinical work.
