A 30-year-old female military veteran with PTSD related to military sexual trauma has been receiving Cognitive Processing Therapy (CPT) for six sessions. She has written her impact statement and identified several beliefs that maintain her distress. One persistent belief is 'The assault was my fault because I should have known better than to trust him.' Despite psychoeducation about the connection between thoughts and feelings, she returns each week endorsing this belief with equal conviction. Her therapist uses Socratic questioning and a structured worksheet to systematically examine the evidence for and against this belief, evaluate whether the belief is based on habit versus fact, and consider alternative interpretations of the event. Which CPT concept and technique are being applied?
