Body vigilance in nonclinical and anxiety disorder samples: structure, correlates, and prediction of health concerns.

The Body Vigilance Scale (BVS) is a measure developed to assess one's conscious attendance to internal cues. The present report investigated the structure, correlates, and predictive utility of the BVS in nonclinical (N=442) and anxiety (N=135) disorder samples. The findings of Study 1 suggest that the BVS is 1-dimensional in a nonclinical sample, and Study 2 replicated the factor structure of the BVS in an anxiety disorder sample. Correlations between the BVS and related (i.e., anxiety sensitivity) and unrelated (i.e., social anxiety) variables were consistent with predictions in both studies. Study 2 also showed that body vigilance is primarily elevated in patients with panic disorder relative to other anxiety disorders. Relative elevations in body vigilance were also observed for patients with hypochondriasis and generalized anxiety disorder. The BVS also demonstrated a specific association with medical utilization and health-related safety-seeking behaviors after controlling for related variables in nonclinical and anxiety disorder samples. The implications of our findings for the nature and measurement of body vigilance as a predictor of health concerns in anxiety disorders are considered.
