About this study
Preliminary clinical evidence suggests that Service Members with symptoms of post-traumatic stress disorder (PTSD) or Post Traumatic Stress (PTS) who participate in the Service Dog Training Program (SDTP) report improved physical and psychological outcomes, including those with overlapping symptoms associated with traumatic brain injury (TBI) and post-concussion symptoms (PCS).
This study intends to examine the psychological, social, and biological effects of learning how to train a future service dog combined with standard of care for individuals with symptoms of Post-Traumatic Stress (PTS), including those with overlapping TBI and persistent Post-Concussive Symptoms (PCS). Biological, social, and behavioral measures will be collected throughout study participation.
Read the detailed description
Preliminary clinical evidence suggests that Service Members with symptoms of post-traumatic stress disorder (PTSD) or Post Traumatic Stress (PTS) who participate in the Service Dog Training Program (SDTP) report improved physical and psychological outcomes, including those with overlapping symptoms associated with traumatic brain injury (TBI) and post-concussion symptoms (PCS). Since 2011, over 3,000 injured Service Members have participated in the SDTP. The program entails teaching Service Members how to train service dogs. Participation in this program helps injured Service Members develop skills, such as attention and discipline, which are needed to successfully shape the dog's behavior and are translatable to other social settings. Further, participation in the program appears to enhance the participants' well-being, quality of life, and relationship with significant others, including their children. Moreover, Service Members (SM) who participate in the SDTP report being motivated to participate in the program for the chance of helping other wounded warriors, who will be the recipients of the dogs that they train.
Despite the reported anecdotal benefits from the SDTP, there has been a lack of prospective controlled research studies that examine the efficacy of the program or the biological basis as to how it may be helpful to improve the underlying disease. This study intends to examine the psychological, social, and biological effects of the SDTP combined with standard of care for individuals with symptoms of Post-Traumatic Stress (PTS), including those with overlapping TBI and persistent Post-Concussive Symptoms (PCS). This study will also seek to identify potential psychological, physiological, and/or biological factors that may influence the degree of response from this noninvasive intervention, as well as its potential impact on disease/symptom modification. Further, for those subjects with family members, it will seek to share data with a parallel study ongoing at the University of Maryland to evaluate the effects of the SDTP on family member stress levels, relationship satisfaction, communication evaluate the effects of the SDTP on family member stress levels, relationship satisfaction, communication and parenting.
To accomplish these aims the researchers will recruit DEERS eligible medical beneficiaries who are experiencing PTS and PCS symptoms. Up to 156 participants will be recruited in the National Capital Region (NCR) for a ten-week longitudinal pre-post study, in which each participant will serve as their own control. Additionally, up to 104 participants will be recruited for a three-week longitudinal parallel randomized study will be available for participants recruited through the National Intrepid Center of Excellence (NICoE) 4-week Intensive Outpatient Program (IOP).
Each participant in the active group will train a service dog using methods that facilitate a relationship between the trainer and dog for the gradual shaping of desired behavior. Self-report measures of behavioral symptoms will be given weekly throughout participation in this study. Biological measures, including blood collection, HR, BP, etc. will be collected at baseline, during the three-week training follow-up, during the six-week training follow-up (NCR participants only), and at a three-month post-training followup (optional for NICoE IOP participants). The researchers will also be collecting self-report assessments from the participant, observational reports from an Occupational Therapist (OT) and electronic health records to track healthcare utilization and social skills (i.e. communication).
The study is being carried out in collaboration with the Center for Neuroscience and Regenerative Medicine (CNRM). Under this collaboration, the study will use the CNRM Core Resources including the CNRM Biorepository. Data stored and shared within the CNRM Data Repository will be coded, and upon destruction of the Master List, de-identified.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in symptom severity using the Post-traumatic Stress Checklist (PCL-5)
A 20-item self-report measure that assesses changes in symptom severity of PTSD to include, monitoring symptom change during/after treatment, screening individuals for PTSD, and making a provisional PTSD diagnosis. This instrument will be used for inclusion criteria for the study as well as to assess change during the course of the study.
Measured: The PCL-5 will be collected at screening as part of the inclusion criteria, and subsequently once a week until the end of the 10-week study period, as well as at the 3-month follow-up visit.
Change in symptom severity using the Generalized Anxiety Disorder-7 (GAD-7)
A 7-item self-report measure that assesses an individual's level of anxiety from 0 (least severe) to 21 (most severe). The measure has excellent internal consistency (Cronbach alpha = 0.92) and test-retest reliability (intraclass correlation = 0.83). GAD-7 takes less than 5 minutes to complete.
Measured: The GAD-7 will be collected once a week from start of study until the end of the 10-week study period, as well as at the 3-month follow-up visit.
Change in symptom severity using the Patient Health Questionnaire (PHQ-9)

Measured: The PHQ-9 will be collected once a week from start of study until the end of the 10-week study period, as well as at the 3-month follow-up visit.
Change in symptom severity using the Connor-Davidson Resilience Scale (CD-RISC)
A 25-item self-report measure to help quantify resilience and, as a clinical measure, to assess treatment response on a scale from 0 (least resilient) to 100 (most resilient). The measure has high internal consistency (Cronbach's alpha = 0.89) and test-retest reliability (intra-class correlation = 0.87).
Measured: The CD-RISC will be completed at the 4-week, 7-week, 10-week, and 3-month follow-up visits.
Change in symptom severity using the Defense and Veterans Pain Rating Scale (DVPRS)
A visual pain scale to assess individual's pain intensity on a scale of 0-10 (10 being most severe pain), with an additional 4 questions to assess pain's interference with the participant's activity, sleep, mood, and stress.
Measured: The DVPRS will be completed at the 4-week, 7-week, 10-week, and 3-month follow-up visits, as well as after each participant training session (twice a week).
Change in symptom severity using the Perceived Stress Scale (PSS)
A 10-item measure that assesses an individual's appraisal of their life stressors from 0 (least perceived stress) to 40 (most perceived stress). The PSS demonstrates good reliability (0.84 to 0.86) and face validity, and it is predictive of biological indicators of stress in humans with correlation coefficients ranging from 0.52 to 0.76 for symptomalogical measures.
Measured: The PSS will be completed at the 4-week, 7-week, 10-week, and 3-month follow-up visits.
Change in symptom severity using the Pittsburgh Sleep Quality Index (PSQI)
A 19-item self-report measure (with 5 additional questions rated by the bedpartner or roommate) evaluating sleep quality and disturbances with lower scores indicating better sleep. The PSQI demonstrates high internal reliability (Cronbach's alpha = 0.83) and test-retest reliability (r = 0.68 to 0.79).
Measured: The PSQI will be completed at the 4-week, 7-week, 10-week, and 3-month follow-up visits.
Change in symptom severity using the CDC's Health-related Quality of Life Instrument (HRQOL-14)
A 14-item self-report measure that assesses quality of life based on "healthy days" measures and symptoms and activity limitations.

Changes in cytokines
Blood collection not exceeding 40 mL per time point. Cytokines strongly associated with PTSD and depression include pro-inflammatory factors IFNG, IL-12, IL-6, and TNF alpha. Cytokines will be measured by multiplex or single immunoassays.
Measured: Blood will be collected at baseline (Week 0-1), Week 3, Week 6, and at the 3 month follow-up visit.
Gene expression
Blood collection not exceeding 40 mL. DNA genomic variants will be measured by whole genome sequencing.
Measured: Blood will be collected at baseline for full genome sequencing.
Secondary outcomes (14)
Changes in scores on Service Dog Training Program (SDTP) Trainer Evaluation Form

A 10-item measure that assesses an individual's appraisal of their life stressors from 0 (least perceived stress) to 40 (most perceived stress). The PSS demonstrates good reliability (0.84 to 0.86) and face validity, and it is predictive of biological indicators of stress in humans with correlation coefficients ranging from 0.52 to 0.76 for symptomalogical measures.
Change in symptom severity using the Pittsburgh Sleep Quality Index (PSQI)
Time frame: The PSQI will be completed at the 4-week, 7-week, 10-week, and 3-month follow-up visits.
A 19-item self-report measure (with 5 additional questions rated by the bedpartner or roommate) evaluating sleep quality and disturbances with lower scores indicating better sleep. The PSQI demonstrates high internal reliability (Cronbach's alpha = 0.83) and test-retest reliability (r = 0.68 to 0.79).
Change in symptom severity using the CDC's Health-related Quality of Life Instrument (HRQOL-14)
Time frame: The HRQOL-14 will be completed at the 4-week, 7-week, 10-week, and 3-month follow-up visits.
A 14-item self-report measure that assesses quality of life based on "healthy days" measures and symptoms and activity limitations.
Changes in cortisol
Time frame: Blood will be collected at baseline (Week 0-1), Week 3, Week 6, and at the 3 month follow-up visit.
Blood collection not exceeding 40 mL per time point.
Changes in cytokines
Time frame: Blood will be collected at baseline (Week 0-1), Week 3, Week 6, and at the 3 month follow-up visit.
Blood collection not exceeding 40 mL per time point. Cytokines strongly associated with PTSD and depression include pro-inflammatory factors IFNG, IL-12, IL-6, and TNF alpha. Cytokines will be measured by multiplex or single immunoassays.
Gene expression
Time frame: Blood will be collected at baseline for full genome sequencing.
Blood collection not exceeding 40 mL. DNA genomic variants will be measured by whole genome sequencing.
14 secondary outcomes
Changes in scores on Service Dog Training Program (SDTP) Trainer Evaluation Form
Time frame: The SDTP Trainer Evaluation Form will be completed by the professional dog trainer after each training session, which occurs twice a week from Week 4 through Week 10.
Lexington Attachment to Pets Scale (LAPS)
Time frame: The LAPS will be collected at Week 4.
Life Events Checklist for DSM-5 (LEC-5)
Time frame: The LEC-5 will be collected at Weeks 4 and 10.
Medical Outcome Study - Social Support Survey (MOS-SSS)
Time frame: The MOS-SSS will be collected at Week 4 and the 3-month follow-up visit.
Neurobehavioral Symptom Inventory (NSI)
Time frame: The NSI will be collected weekly from start of session through the 10-week training period, and again at the 3-month follow-up visit.
Pet Attitude Scale (PAS)
Time frame: The PAS will be collected at the Week 4 visit.
Ohio State University TBI Identification Method - Short Form (OSU-TBI-ID-SF)
Time frame: The OSU-TBI will be collected at Week 4.
Assessment of Communication and Interaction Skill (ACIS)
Time frame: The ACIS will take place at the start of study, then subsequently every 3 weeks until the end of the 10-week training period. It will be administered once more at the 3-month follow-up visit.
Changes in Heart Rate
Time frame: Heart rate will take place at all major study visits (Weeks 4, 7, 10, and 3-month follow-up), as well as during each training session twice a week from Week 4 through Week 10.
Changes in Blood Pressure
Time frame: Blood pressure will take place at all major study visits (Weeks 4, 7, 10, and 3-month follow-up), as well as during each training session twice a week from Week 4 through Week 10.
Changes in Anthropometric Data measured in inches
Time frame: Anthropometric data will be collected at Weeks 4, 7, 10, and the 3-month follow-up visit.
Changes in Weight
Time frame: Weight measurements will be collected at Weeks 4, 7, 10, and the 3-month follow-up visit.
Qualitative Interview
Time frame: The Qualitative Interview will take place at Week 10 and the 3-month follow-up visit.
Changes in number of medical visits
Time frame: Healthcare Utilization Records will be updated during the major study visits at Week 0, Week 4, Week 7, Week 10, and the 3-month follow-up visit.
