Area of Science:

  • Psychology
  • Psychiatry

Background:

  • Delusions are increasingly understood as defense mechanisms against negative self-evaluation.
  • Cognitive therapy for delusions should more explicitly address self-evaluation issues.
  • Connecting delusions to self-esteem can be challenging in clinical practice.

Observation:

  • This study presents a single-case cognitive therapy approach for paranoia and negative self-evaluative beliefs.
  • A multiple-baseline design sequentially challenged one negative self-evaluative belief and two paranoid delusions.
  • The participant had strong negative self-evaluative beliefs and paranoid delusions.

Findings:

  • Conviction in two out of three challenged beliefs significantly decreased post-intervention.
  • Conviction in the third belief diminished even before the specific intervention.
