Responses to false physiological feedback in individuals with panic attacks and elevated anxiety sensitivity.

Area of Science:

• Psychology
• Psychophysiology
• Anxiety Disorders

Background:

• Anxiety sensitivity and panic attack history are linked to heightened reactivity.
• Understanding physiological and subjective responses to internal cues is crucial for panic disorder research.

Purpose of the Study:

• To investigate physiological and subjective reactivity to false heart-rate feedback in individuals with and without panic attack history.
• To examine the influence of a priming procedure on responses to false feedback.
• To differentiate between general anxiety and panic-specific symptoms in response to false feedback.

Main Methods:

• Comparison of high-risk (elevated anxiety sensitivity, panic history) and low-risk (low anxiety) groups.
• Exposure to accurate and false heart-rate feedback.
• Administration of a priming procedure.
• Measurement of physiological and subjective reactivity.

Main Results:

• False heart-rate feedback elicited significant physiological and subjective responses in all participants.
• Panic attack frequency predicted reactions to false feedback in the high-risk group.
• High-risk participants reported more panic-specific symptoms, irrespective of sex.

Conclusions:

• False perception of internal bodily changes may contribute to panic disorder risk.
• Panic attack symptoms in response to false feedback are specific to risk group, not sex.
• The experimental paradigm provides insights into interoception and panic disorder.
