Summary

This study compares the relative efficacy of three methods of delivering interoceptive exposure for the reduction of elevated anxiety sensitivity. The interventions vary according to their intensity and use of coping strategies during exposure. An expressive writing intervention serves as an expectancy control.

Conditions

  • Anxiety Sensitivity

Interventions

BEHAVIORAL

Standard exposure

Three 60-second trials of hyperventilation, each followed by diaphragmatic breathing, cognitive reappraisal, and prolonged rest until body sensations have subsided.

BEHAVIORAL

Enhanced exposure

Three 60-second trials of hyperventilation, each followed by a 15-second rest period and cognitive reappraisal.

BEHAVIORAL

Intensive exposure

Minimum of eight 60-second hyperventilation trials, each followed by 15-second rest period and cognitive reappraisal. Trials continue until participants rate the probability that their most feared outcome will occur as less than 5% on a 0% to 100% scale.

BEHAVIORAL

Expressive writing

Individuals randomized to the expressive writing control group will receive a rationale for why writing about emotional issues helps resolve the fear of body sensations. These participants will then be asked to spend the next 25 minutes writing about past emotional issues. Participant writings are confidential and will not be viewed by the experimenter.
