Transdiagnostic understandings of mental disorders are expected to provide more accurate and detailed descriptions of psychopathology and be helpful in developing efficient treatments. Although conventional clustering techniques, such as latent profile analysis, are useful for the taxonomy of psychopathology, they provide little implications for targeting specific symptoms in each cluster. To overcome these limitations, we introduced Gaussian graphical mixture model (GGMM)-based clustering, a method developed in mathematical statistics to integrate clustering and network statistical approaches. To illustrate the technical details and clinical utility of the analysis, we applied GGMM-based clustering to a Japanese sample of 1,521 patients (<jats:italic>M<\/jats:italic><jats:sub>age<\/jats:sub>= 42.42 years), who had diagnostic labels of major depressive disorder (MDD;<jats:italic>n<\/jats:italic>= 406), panic disorder (PD;<jats:italic>n<\/jats:italic>= 198), social anxiety disorder (SAD;<jats:italic>n<\/jats:italic>= 116), obsessive-compulsive disorder (OCD;<jats:italic>n<\/jats:italic>= 66), comorbid MDD and any anxiety disorder (<jats:italic>n<\/jats:italic>= 636), or comorbid anxiety disorders (<jats:italic>n<\/jats:italic>= 99). As a result, we identified the following four transdiagnostic clusters characterized by i) strong OCD and PD symptoms, and moderate MDD and SAD symptoms; ii) moderate MDD, PD, and SAD symptoms, and weak OCD symptoms; iii) weak symptoms of all four disorders; and iv) strong symptoms of all four disorders. Simultaneously, a covariance symptom network within each cluster was visualized. The discussion highlighted that the GGMM-based clusters help us generate clinical hypotheses for transdiagnostic clusters by enabling further investigations of each symptom network, such as the calculation of centrality indexes.<\/jats:p>","DOI":"10.1371\/journal.pone.0256902","type":"journal-article","created":{"date-parts":[[2021,9,1]],"date-time":"2021-09-01T17:29:07Z","timestamp":1630517347000},"page":"e0256902","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":5,"title":["Classifying
