What Does ‘High Anxiety Sensitivity’ Look Like? Using Cluster Analysis to Identify Distinct Profiles of High Anxiety Sensitive Treatment-Seekers

Anxiety sensitivity (AS) is a transdiagnostic risk factor for mental health disorders. While its lower order factors – social, physical, and cognitive concerns – and their associations with emotional disorders have been examined independently of each other, research has not fully appreciated that these factors might appear to different degrees in individuals, with psychopathology implications. We used cluster analysis to investigate how the lower order AS factors appear in treatment-seekers with high AS and how these manifestations of AS (i.e., the different clusters) are uniquely associated with psychopathology. Participants (N = 154; from two studies) were high AS treatment-seeking adults with anxiety and/or depressive disorders who completed a diagnostic interview and self-report measures of AS and anxiety and depression symptoms. A four-cluster solution emerged including a Multidimensional cluster (33.8
