The relation of anxiety sensitivity to higher and lower order personality dimensions: implications for the etiology...

The relation of anxiety sensitivity (AS) to personality dimensions has received little attention. In this study, 4 AS indexes were administered along with measures of personality, fears, and panic attacks to 220 undergraduates. At the higher order level, AS was positively correlated with negative emotionality (NE) but was largely unrelated to either positive emotionality or constraint. At the lower order level, AS was positively correlated with absorption and NE indexes. Most of these correlations were significant even among participants with no panic attack history. AS exhibited incremental validity above and beyond a number of personality variables, including absorption and trait anxiety, in the prediction of fears and panic attack history. These findings are consistent with the hypothesis that a propensity toward immersion in sensory experiences is a diathesis for panic attacks.
