A Preliminary Analysis of Psychiatric Service Dog Placements and Sleep Patterns of Partners of Veterans with PTSD

ABSTRACTPartners of veterans diagnosed with posttraumatic stress disorder (PTSD) are at risk of a variety of challenges, and it is unknown whether psychiatric service dogs are disruptive to their sleep or provide similar benefits that are seen in the limited literature on veterans. As part of a larger clinical trial examining the efficacy of psychiatric service dogs for veterans with PTSD and their families, this study focused on sleep patterns of veterans’ partners (n = 88), incorporating both subjective (clinically validated self-report surveys) and objective sleep measures (actigraphy). Linear regression was used to analyze differences in relation to group (intervention versus control) at follow-up, controlling for baseline score. Results revealed no significant differences between groups for both the subjective surveys (p = 0.15; p = 0.75) and the objective actigraphy measures (p = 0.06–0.98). This suggests that psychiatric service dogs are not disruptive, nor do they provide any benefits to partner sleep. Partners had sleep patterns on par with national norms at baseline and remained at such levels at follow up. Ultimately, using both subjective and objective measures, we found no impact of psychiatric service dogs on the sleep of veterans’ partners.Trial registration: ClinicalTrials.gov identifier: NCT03245814.KEYWORDS: Animal-assisted interventionassistance doghuman–animal interactionmilitary families AcknowledgementsThank you to all the partners, veterans, and service dogs who made this study possible.Disclosure StatementNo potential conflict of interest was reported by the authors.Additional informationFundingThis work was supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) and the National Center for Complementary and Integrative Health (NCCIH) of the National Institutes of Health (NIH) under award number R21HD091896; and Merrick PetCare.
