Abstrakt: Background: Patients with PTSD often voice concern over their perceived change in cognitive functioning. However, these negative appraisals do not always align with objective neuropsychological performance, yet are strongly predictive of PTSD symptom severity and self-reported functional impairment.
Methods: The present study involves a secondary analysis examining the role of appraisals of a subsample of 81 adults with full or subthreshold PTSD on treatment outcomes in a randomized controlled trial investigating the effectiveness of a cognitive rehabilitation treatment, Strategic Memory and Reasoning Training (n = 38), compared to a psychoeducation control arm, the Brain Health Workshop (n = 43). Neither condition addressed PTSD symptoms, focusing instead on cognitive skills training and psychoeducation about the brain.
Results: Intent-to-treat models showed statistically significant improvements for both groups on composite scores of executive functioning and memory. Additionally, both groups experienced clinically significant reductions in PTSD symptoms (assessed via the Clinician-Administered PTSD Interview) and the SMART group showed fewer negative appraisals about cognitive functioning following training. Change in appraisals of cognitive functioning was associated with change in PTSD as well as change in quality of life, with no differential associations based on group status. In contrast, neurocognitive test score changes were not associated with change in symptoms or functional outcomes.
Limitations: We did not collect data on other appraisals (e.g., self-efficacy), which could have further elucidated pathways of change.
Conclusions: Our findings suggest that interventions that do not directly target PTSD symptoms can lead to PTSD symptom change via change in appraisals of functioning.
