Objective Cognitive processing therapy is an evidence‐based treatment for posttraumatic stress disorder (PTSD); however, questions remain regarding variability in treatment response. Method A total of 123 veterans participated in group‐based cognitive processing therapy (CPT) in residential PTSD treatment. Change over time in PTSD symptoms was modeled as a function of selected demographic and clinical variables. Results PTSD checklist (PCL) scores decreased by an average of 1 point per session (standard deviation [ SD ] = 0.1). Initial PCL scores were predicted by the Beck Depression Inventory‐II (γ 01 = 0.25; standard error [ SE ] = 0.08), Insomnia Severity Index (γ 02 = 0.53; SE = 0.15), and Infrequency ( F ) scale of the Minnesota Multiphasic Personality Inventory‐2 (γ 03 = 0.09; SE = 0.04). Rate of change was predicted by the Somatic Complaints (RC1) scale (γ 11 = −0.03; SE = 0.01) and the Antisocial Behavior (RC4) scale (γ 12 = 0.02; SE = 0.01). Conclusions These results provide insight into characteristics that may influence degree of benefit received from group‐based CPT.
