Abstract
Numerous studies have demonstrated the efficacy of cognitive processing therapy (CPT) for treating posttraumatic stress disorder (PTSD). Two prior meta-analyses of studies are available but used approaches that limit conclusions that can be drawn regarding the impact of CPT on PTSD outcomes. The current meta-analysis reviewed outcomes of trials that tested the efficacy of CPT for PTSD in adults and evaluated potential moderators of outcomes. All published trials comparing CPT against an inactive control condition (i.e. psychological placebo or wait-list) or other active treatment for PTSD in adults were included, resulting in 11 studies with a total of 1130 participants. CPT outperformed inactive control conditions on PTSD outcome measures at posttreatment (mean Hedges' g = 1.24) and follow-up (mean Hedges' g = 0.90). The average CPT-treated participant fared better than 89% of those in inactive control conditions at posttreatment and 82% at follow-up. Results also showed that CPT outperformed inactive control conditions on non-PTSD outcome measures at posttreatment and follow-up and that CPT outperformed other active treatments at posttreatment but not at follow-up. Effect sizes of CPT on PTSD symptoms were not significantly moderated by participant age, number of treatment sessions, total sample size, length of follow-up, or group versus individual treatment; but, older studies had larger effect sizes and percent female sex moderated the effect of CPT on non-PTSD outcomes. These meta-analytic findings indicate that CPT is an effective PTSD treatment with lasting benefits across a range of outcomes.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
