A 42-year-old female veteran has been receiving Cognitive Processing Therapy (CPT) for PTSD related to military sexual trauma. During session 7, she presents her ABC worksheet and states, 'I have realized I keep telling myself that what happened was my fault because I should have fought harder. But I know logically that I froze because of fear, and that is a normal trauma response.' She pauses and adds, 'Even though I understand it intellectually, I still feel deep down that it was my fault.' The PMHNP recognizes this as a common pattern in CPT. What is the MOST appropriate next intervention?
