Anxiety sensitivity (AS), the fear of anxiety symptoms, has a hierarchical structure. A new 60-item profile identified four specific factors contributing to this fear, impacting anxiety disorder development.

Area of Science:

  • Psychology
  • Clinical Psychology
  • Psychopathology

Background:

  • Anxiety sensitivity (AS) is a key diathesis for anxiety disorders, especially panic disorder.
  • AS is theorized to have a hierarchical structure with lower-order and higher-order factors.
  • Previous measures, like the 16-item Anxiety Sensitivity Index (ASI), may lack the granularity to fully elucidate AS structure.

Purpose of the Study:

  • To develop and validate a more comprehensive measure of AS.
  • To investigate the detailed hierarchical structure of AS.
  • To identify specific lower-order factors contributing to AS.

Main Methods:

  • Development of the 60-item Anxiety Sensitivity Profile (ASP).
  • Administration of the ASP to 349 university students.

  • Factor analyses to determine the hierarchical structure of AS.

    • Main Results:

    • Factor analyses revealed a hierarchical structure for AS.
    • Four lower-order factors were identified: fear of respiratory symptoms, cognitive dyscontrol, gastrointestinal symptoms, and cardiac symptoms.
    • These four factors loaded onto a single higher-order factor, with unique variance in each.

    Conclusions:

    • AS appears to be a general factor with independent contributions from specific symptom-related fears.
    • The findings support a hierarchical model of AS, with distinct mechanisms contributing to the overall construct.
    • The Anxiety Sensitivity Profile offers a more detailed assessment of AS, potentially improving understanding of its role in anxiety disorders.
