However, needs assessment surveys focus largely on individual disorders rather than on comorbidity even though the latter is more important for predicting suicidal thoughts and behaviors. In the current report, we take a step beyond this conventional approach by presenting data on the prevalence and correlates (sociodemographic factors, college\u2010related factors, and suicidal thoughts and behaviors) of the main multivariate profiles of common comorbid <jats:italic>Diagnostic and Statistical Manual of Mental Disorders<\/jats:italic> (DSM)\u2010IV disorders among students participating in the first phase of the World Health Organization World Mental Health International College Student initiative.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>A web\u2010based mental health survey was administered to first year students in 19 colleges across eight countries (Australia, Belgium, Germany, Mexico, Northern Ireland, South Africa, Spain, United States; 45.5% pooled response rate) to screen for seven common DSM\u2010IV mental disorders: major depression, mania\/hypomania, generalized anxiety disorder, panic disorder, attention\u2010deficit\/hyperactivity disorder, alcohol use disorder, and drug use disorder. We focus on the 14,348 respondents who provided complete data; 38.4% screened positive for at least one 12\u2010month disorder.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Multivariate disorder profiles were detected using latent class analysis (LCA). The least common class (C1; 1.9% of students) was made up of students with high comorbidity (four or more disorders, the majority including mania\/hypomania). The remaining 12\u2010month cases had profiles of internalizing\u2013externalizing comorbidity (C2; 5.8%), internalizing comorbidity (C3; 14.6%), and pure disorders (C4; 16.1%). The 1.9% of students in C1 had much higher prevalence of suicidal thoughts and behaviors than other students. Specifically, 15.4% of students in C1 made a suicide attempt in the 12\u00a0months before the survey compared with 1.3\u20132.6% of students with disorders in C2\u20134, 0.2% of students with lifetime disorders but no 12\u2010month disorders (C5), and 0.1% of students with no lifetime disorders (C6).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In line with prior research, comorbid mental disorders were common; however, sociodemographic correlates of LCA profiles were modest.
