  • Anxiety sensitivity, disgust sensitivity and aversive reactions to four stimuli

    Behavioural and Cognitive Psychotherapy / Volume 49 / Issue 2 / March 2021

  • Background:

    Prior theory and research has implicated disgust as relevant to some, but not all phobias.

    Aims:

    The current study examined whether anxiety sensitivity is more relevant to certain specific phobias and whether disgust sensitivity is more relevant to other specific phobias.

    Method:

    Participants (n = 201) completed measures of anxiety sensitivity, disgust sensitivity and measures of aversive reactions in the presence of two fear-relevant stimuli (i.e. heights and small, enclosed spaces) and two disgust-relevant stimuli (i.e. spiders and blood/injury).

    Results:

    Results of multiple linear regression analyses revealed that disgust sensitivity showed significant associations with aversive reactions in all four stimulus domains after controlling for anxiety sensitivity. After controlling for disgust sensitivity, anxiety sensitivity showed associations with the two fear-relevant phobias but not with the two disgust-relevant phobias included in this study. Anxiety sensitivity also showed an association with variance specific to one of the two fear-relevant specific phobias included in the study. Disgust sensitivity also showed associations with variance specific to both of the disgust-relevant phobias included in the study but not with variance specific to either of the fear-relevant specific phobias.

    Conclusions:

    These results provide evidence that the distinction between fear-relevant and disgust-relevant specific phobias is meaningful and also implicate disgust sensitivity as relevant to aversive reactions to all stimuli included in this study.

  • Summary

    The number of minimally invasive procedures and diagnostic imaging examinations requiring moderate sedation has increased greatly in the radiology department. Many procedures in radiology are performed with the use of iodinated contrast media, and safe use of contrast media is important to everyday radiology practice. Providing moderate sedation in the magnetic resonance imaging (MRI) suite presents both patient and environmental challenges. The most common need for moderate sedation in MRI arises from severe anxiety from claustrophobia while in the scanner. It is important to limit patient movement to acquire clear diagnostic images, and in some instances patients require deep sedation or general anesthesia administered by an anesthesiologist. The American College of Radiology and the Joint Commission have published safety guidelines and alerts, and all personnel working in the MRI environment must review these guidelines and receive facility-specific safety training and screening prior to caring for patients in the environment.
