Interpretation of ambiguous interoceptive stimuli in panic disorder and nonclinical panic

Cognitive bias in the misinterpretation of ambiguous interoceptive stimuli has been demonstrated in panic disorder This study investigated whether this cognitive bias also occurs in people with nonclinical panic who are at risk of developing panic disorder. The responses of 25 people with nonclinical panic were compared to those of 20 people with panic disorder and 69 nonpanic controls on a measure of interpretive bias, the Brief Body Sensations interpretation Questionnaire. There was evidence for interpretive cognitive bias for ambiguous interoceptive stimuli among the nonclinical panickers which did not differ from that of the people with panic disorder, bur which differed from the nonpanic controls. High anxiety sensitivity predicted interpretive bias toward both interoceptive and external stimuli. Results therefore suggest that interpretive cognitive bias for ambiguous interoceptive stimuli may be a risk factor for the development of panic disorder.
