Abbreviations: CAPS = Clinician Administered PTSD Scale; CBTi = Cognitive Behavioral Therapy for Insomnia; CI = Confidence Interval; CPT = Cognitive processing Therapy ES = effect size; HAM-D = Hamilton Depression Rating Scale; ISI = Insomnia Severity Index

All analyses are intent-to-treat ANCOVAs with missing values imputed and controlling for gender, age, education, minority status, recruitment site, antidepressant medication use, baseline lifetime traumatic events, baseline PTSD severity, baseline depression, and the dependent variable’s baseline value.

^aTotal scale scores with insomnia items removed are the planned primary outcomes.

^bThe p-values displayed have not been corrected for multiplicity. Significance is therefore set at p < 0.017.
