Abstract Evidence describing the association between sleep quality and trauma‐focused therapy is mixed. This secondary analysis of a primary care sample examined whether (a) baseline moderated posttraumatic stress disorder (PTSD) symptom severity over time across groups receiving different doses cognitive processing (CPT) (b) improved with CPT. Participants were 227 adults who screened positive for PTSD participating in clinical trial comparing two models treatment delivery care. The Pittsburgh Sleep Quality Index (PSQI) Checklist DSM‐5 (PCL‐5) used to assess disturbance severity, respectively. Multiple linear regression was PSQI scores 12‐month PCL‐5 CPT dosage (0 sessions: 51.1%, 1–7 31.7%; ≥ 8 sessions [adequate dose]: 17.2%) differed by group at follow‐up. Post hoc analyses changes items. Baseline did not moderate effect on among participants an adequate dose, p > .112. B = ‐2.63, SE 0.75, < .001. Differences change Item 2, F (2, 435) 11.34, 20, H (2) 32.04, indicated that dose had greater reductions trauma‐related symptoms than those received 0–7 sessions, s Residual post‐CPT impairment despite improvement warrants further interventions.
