Presence of Psychiatric Assistance Dogs and Relation to Post-Traumatic Stress Disorder Treatment Outcomes: A Nonrandomized, Observational Study in a Military Sample

Abstract

The purpose of this study was to examine differences between military veterans and service members with and without a psychiatric assistance dog (PAD) who were receiving cognitive behavioral therapy (CBT) for post-traumatic stress disorder (PTSD). Six hundred eighty-two military veterans presented at a 2-week intensive, outpatient CBT program for PTSD from February 2016 to February 2020. Self-reports of symptoms and rates of treatment completion by PAD ownership were assessed. Patients with PADs ( n = 93) reported higher scores on the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) ( P = .04; Cohen's d = 0.23) and Neurobehavioral Symptom Inventory ( P < .01; Cohen's d = 0.34) at baseline. PTSD symptom change was comparable between participants with and without PADs ( P > .05). Dropout was higher among owners of PADs, but this difference was not significant ( P = .11). Among military populations, those with PADs may experience more severe PTSD and neuro-cognitive symptoms, but having a PAD was not associated with treatment outcome in intensive CBT.
