Anxiety sensitivity in agoraphobics.

R J McNally, M Lorenz

    Journal of Behavior Therapy and Experimental Psychiatry
    |March 1, 1987

    Summary

    The Anxiety Sensitivity Index (ASI) effectively measures fear of anxiety in agoraphobics. While ASI scores decreased with treatment, residual sensitivity did not predict avoidance relapse, suggesting it

    Area of Science:

    • Psychology
    • Clinical Psychology
    • Anxiety Disorders

    Background:

    • Anxiety sensitivity, the fear of anxiety-related sensations, is a key factor in understanding anxiety disorders.
    • The Reiss-Epstein-Gursky Anxiety Sensitivity Index (ASI) is a widely used measure for assessing this construct.
    • Previous research suggests a link between anxiety sensitivity and the development and maintenance of phobic avoidance.

    Purpose of the Study:

    • To further validate the ASI as a measure of fear of anxiety.
    • To examine the relationship between anxiety sensitivity and treatment outcomes in agoraphobia.
    • To differentiate the construct of anxiety sensitivity from general anxiety and other "fear of fear" measures.

    Main Methods:

    • Longitudinal study involving agoraphobic participants undergoing behavioral treatment.
    • Administration of the ASI before and after treatment, and at a six-month follow-up.
    • Multiple regression analyses to assess the predictive validity of ASI scores.

    Main Results:

    • Agoraphobic participants exhibited high ASI scores pre-treatment, which significantly decreased post-treatment.
    • Residual anxiety sensitivity did not predict the resurgence of agoraphobic avoidance at follow-up.
    • Anxiety sensitivity continued to decline during the follow-up period.
    • The ASI uniquely predicted the number of fears in agoraphobics, independent of general anxiety levels.

    Conclusions:

    • The ASI is a valid and reliable measure for assessing fear of anxiety.
    • While anxiety sensitivity decreases with effective treatment, it may not be the sole predictor of long-term avoidance.
    • Anxiety sensitivity appears to be a distinct construct from general anxiety, playing a role in fear acquisition.
