A brief screen for panic disorder

Phenotypic and genetic structure of anxiety sensitivity in adolescence and early adulthood

“…This factor could explain the strong associations observed between total anxiety sensitivity and panic, where bodily signs of anxiety (e.g. heart palpitations) are a core source of fear and predict the onset of a panic attacks (Apfeldorf, Shear, Leon, & Portera, 1994). Similarly, previous item-level analyses of anxiety sensitivity measures find strong associations between items captured in, what is referred to here, as the Social concerns factor and measures of social phobia (Cox et al, 1999); and those in what is referred to as 'Mental concerns' and depression (Taylor, Koch, Woody, & McLean, 1996).…”

Pain-related anxiety and anxiety sensitivity across anxiety and depressive disorders

“…AS has been shown to be extremely high in people with PD (Apfeldorf, Shear, Leon, & Portera, 1994;Taylor et al, 1992), such that the ASI can be used to differentiate people with and without the disorder. Accordingly, if pain-related anxiety is a manifestation of AS, it was reasonable to predict that people with PD would also score highest on pain-related anxiety because AS is typically highest in people with PD relative to other anxiety disorder categories (Taylor et al, 1992).…”

Panic disorder subtypes: further clinical differences

“…A high Anxiety Sensitivity Index (ASI) score is a cognitive risk factor for PD. Studies have repeatedly demonstrated the relationship between high AS level and PD [Apfledorf et al, 1994;McNally and Lorenz, 1987;Schmidt et al, 1997]. The ASI [Peterson and Reiss, 1992], which taps fear of anxiety-related sensations and symptoms, has been shown to be the predictor of respiratory challenges (hyperventilation and CO 2 ) in PD [Donnell and McNally, 1989;Eke and McNally, 1996;Rapee et al, 1992].…”
