Anxiety sensitivity, the fear of physical or psychological symptoms, can be separate from panic attacks. This study found distinct clusters for panic symptoms and anxiety sensitivity, suggesting a cognitive component to panic disorder.

Area of Science:

  • Psychology
  • Psychiatry
  • Clinical Psychology

Background:

  • Panic disorder is characterized by recurrent panic attacks.
  • Anxiety sensitivity is a proposed vulnerability factor for panic disorder.
  • The relationship between specific panic symptoms and anxiety sensitivity requires further clarification.

Purpose of the Study:

  • To investigate the relationship between 23 panic attack symptoms and the 16 items of the Anxiety Sensitivity Index.
  • To identify underlying factors of panic symptoms and anxiety sensitivity in panic disorder patients.
  • To examine the independence of anxiety sensitivity from panic symptomatology.

Main Methods:

  • Factor analysis was applied to data from 209 patients diagnosed with panic disorder.
  • The analysis examined the correlation between specific panic attack symptoms and Anxiety Sensitivity Index items.

  • A five-factor model was developed to represent panic symptom clusters and anxiety sensitivity factors.

    • Main Results:

    • A five-factor model emerged, comprising three panic symptom clusters (cardio-respiratory, dizziness-related, cognitive) and two anxiety sensitivity factors (fear of physical symptoms, fear of psychological symptoms).
    • This model explained 50% of the variance in the data.
    • The cognitive panic symptom 'fear of dying' loaded onto the anxiety sensitivity factor 'fear of physical sensations,' indicating partial independence.

    Conclusions:

    • Anxiety sensitivity can be independent of panic symptomatology.
    • Findings support a cognitive model of panic, where catastrophic cognitions are linked to cognitive style rather than symptom severity.
    • This suggests that interventions targeting cognitive aspects may be beneficial for panic disorder.
