Specifically, it sought to identify emotional-loneliness profiles through cluster analysis and evaluate their association with clinical characteristics and diagnostic categories.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Method<\/jats:title>\n            <jats:p>A total of 371 participants (220 with EDs and 151 healthy controls) completed self-report measures including the Wong and Law Emotional Intelligence Scale (WLEIS), the UCLA Loneliness Scale, and the Eating Disorder Examination Questionnaire (EDE-Q). K-means cluster analysis was performed on standardized WLEIS and UCLA scores. Between-group comparisons and post hoc tests were conducted to assess differences across clusters in ED severity, BMI, age, and diagnosis. Logistic and chi-square analyses explored diagnostic distribution and predictive associations.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Three distinct clusters emerged: (1) Low Emotional Intelligence\/High Loneliness (<jats:italic>n<\/jats:italic>\u2009=\u2009130), (2) Moderate EI\/Moderate Loneliness (<jats:italic>n<\/jats:italic>\u2009=\u2009141), and (3) High EI\/Low Loneliness (<jats:italic>n<\/jats:italic>\u2009=\u2009100). Cluster 1 showed the most adaptive profile, while Cluster 0 exhibited the highest ED severity and loneliness. Diagnostic category distribution differed significantly across clusters (\u03c7\u00b2(8)\u2009=\u200989.56, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001), but emotional profiles did not align exclusively with specific diagnoses, supporting a transdiagnostic model.
