Summary

Cognitive-behavioral therapy for bulimia nervosa has moderate success. Experimental cognitive approaches, focusing on attentional biases and blocking aversive self-awareness, may improve treatments for bulimia nervosa and impulsivity.

Area of Science:

  • Clinical Psychology
  • Cognitive Neuroscience
  • Psychopathology

Background:

  • Cognitive-behavioral treatments (CBT) are standard for bulimia nervosa but yield moderate remission rates.
  • Current CBT models may benefit from integration with experimental cognitive approaches.
  • Information processing models offer insights into attentional biases and schema avoidance in eating disorders.

Purpose of the Study:

  • To review and revise cognitive-behavioral models of bulimia nervosa using experimental cognitive approaches.
  • To explore the role of attentional biases and schema avoidance in the etiology and maintenance of bulimia nervosa.
  • To examine the relationship between bulimic behaviors, impulsivity, and the concept of 'blocking' aversive self-awareness.

Main Methods:

  • Literature review synthesizing findings from cognitive psychology and psychopathology research.

  • Analysis of information processing models, including attentional biases and schema avoidance.
  • Examination of evidence linking bulimic behaviors to 'blocking' mechanisms and impulsivity.

    • Main Results:

    • Attentional biases and schema avoidance are implicated in the development and persistence of bulimia nervosa.
    • Bulimic behaviors may serve to block aversive self-awareness, a function also observed in impulsive disorders.
    • A potential overlap exists between the functions of bulimic behaviors and other impulsive behaviors.

    Conclusions:

    • Experimental cognitive approaches can enhance current models of bulimia nervosa.
    • Understanding 'blocking' mechanisms and impulsivity is crucial for refining bulimia nervosa treatments.
    • Further research is needed to clarify the functional relationship between bulimia and impulsivity for clinical application.
