Of 12-month cases, 22.3% were classified as serious; 37.3%, moderate; and 40.4%, mild. Fifty-five percent carried only a single diagnosis; 22%, 2 diagnoses; and 23%, 3 or more diagnoses. Latent class analysis detected 7 multivariate disorder classes, including 3 highly comorbid classes representing 7% of the population.<h4>Conclusion</h4>Although mental disorders are widespread, serious cases are concentrated among a relatively small proportion of cases with high comorbidity.","journal":"Archives of General Psychiatry","year":2005,"id":9868,"datarank":14.902667289609475,"base_score":9.399885773859458,"endowment":9.399885773859458,"self_citation_contribution":1.4099828660789189,"citation_network_contribution":13.492684423530557,"self_endowment_contribution":1.4099828660789189,"citer_contribution":13.492684423530557,"corpus_percentile":93.2,"corpus_rank":948,"citation_count":12086,"citer_count":186,"citers_with_citation_signal":186,"citers_with_endowment":186,"datacite_reuse_total":0,"is_dataset":false,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2005-06-01","authors":[{"id":84747,"name":"Wai Tat Chiu","orcid":"0000-0003-4836-0972","position":1,"is_corresponding":false},{"id":69363,"name":"Olga Demler","orcid":"0000-0003-3355-3210","position":2,"is_corresponding":false},{"id":69368,"name":"Ellen E.
