Anxiety, depression, and the suicidal spectrum: a latent class analysis of overlapping and distinctive features

摘要: Anxiety and depression diagnoses are associated with suicidal thoughts behaviours. However, a categorical understanding of these associations limits insight into identifying dimensional mechanisms suicide risk. This study investigated anxious depressive features through lens risk, independent diagnosis. Latent class analysis 97 depression, anxiety, suicidality-related items among 616 psychiatric outpatients indicated 3-class solution, specifically: (1) higher suicide-risk uniquely differentiated from both other classes by high reported levels arousal; (2) lower that anxiety sensitivity generalised worry comparable to Class 1, but (3) low non-suicidal relatively across all measures. Discriminants the included borderline personality disorder; report worthlessness, crying, sadness; arousal negative affect; positive affect. Depression were not discriminant between risk classes. transdiagnostic approach spectrum contrasts treating it as symptom, illustrates advantages tripartite model for conceptualising
