Evaluating the Feasibility of RESCUE: An Adjunctive HAI-Based Intervention for Veterans With PTSD (RESCUE)

January 21, 2020 updated by: Charleston Research Institute

Evaluating the Feasibility of Recovery Through Engagement With Shelter Canines, Understanding, and Exposure (RESCUE): An Adjunctive Human Animal Interaction (HAI)-Based Intervention for Veterans With PTSD

To develop and pilot test feasibility, acceptability, and efficacy of an adjunct intervention for use with Empirically Based Treatments (EBT) for posttraumatic stress disorder (PTSD) in order to increase treatment engagement, treatment completion, and improve treatment response regarding emotional numbing symptoms. Recovery through Engagement with Shelter Canines, Understanding, and Exposure (RESCUE), is an adjunctive, Human Animal Interaction (HAI) intervention that will be developed for integration into Prolonged Exposure (PE) treatment. Feasibility, acceptability, and initial efficacy testing of the experimental treatment condition will be conducted in a pilot crossover randomized controlled trial (RCT) conducted with 75 veterans with PTSD randomly assigned to RESCUE delivered with PE (RESCUE+PE) or to standard PE initiation (PE + delayed RESCUE).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Veterans with a principal Diagnostic and Statistical Manual-5th edition (DSM-5) PTSD diagnosis (via CAPS) stemming from a Criterion A event.
  2. Men or women aged 18 to 64 inclusive.
  3. Given that individuals with PTSD often have comorbid psychiatric disorders, participants with comorbid depressive, anxiety, substance use disorders, and personality disorders other than Antisocial Personality Disorder will be included as long as PTSD is the primary disorder
  4. Individuals with the ability to comprehend and satisfactorily comply with protocol requirements and who sign the written informed consent given prior to entering any study procedure

Exclusion Criteria:

  1. Individuals with active substance use disorders that require medical detoxification will be initially excluded from participation, but will be eligible once they have completed their detoxification.
  2. Veterans with comorbid Antisocial Personality Disorder, or history of animal cruelty will be excluded. Veterans with comorbid disorders that fall into the following DSM-5 categories will also be excluded: delirium, dementia, amnestic disorders, other cognitive disorders and psychotic disorders. Veterans with active Bipolar I or II and are not on a stable medication regime will be excluded.
  3. Given evidence suggesting that benzodiazepine medications restrict the therapeutic benefits of PE, potential participants will be required to taper and cease use under supervision of their prescribing physician. Participants must be off benzodiazepines for at least two weeks prior to enrolling in the study. Patients using antidepressant medication for PTSD will be eligible for participation as long as they are on a stable regimen (i.e., consistent dose for at least two weeks prior to enrollment and throughout the study).
  4. For safety purposes, Veterans who based on history or mental status examination have a significant risk of committing suicide, or who are homicidal or violent and who are in the Investigator's opinion in significant imminent risk of hurting others, will be excluded.
  5. Patients who are unable to speak, read, and understand English or are judged by the investigator to be unable or unlikely to follow the study protocol and complete all scheduled visits.
  6. Patients who report a dog phobia or are otherwise opposed to working with dogs.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: RESCUE+PE
RESCUE is designed to adapt to individualized needs based on each veteran's performance. The volunteer training consists of weekly sessions lasting 90 minutes each and occurring at area Society for the Prevention of Cruelty to Animals (SPCA) facilities.All veterans will receive individualized, evidence-based prolonged exposure therapy. Foa's PE protocol will be used given consensus statements indicating that exposure therapy is currently the most appropriate psychotherapy for PTSD.
Behavioral: RESCUE
RESCUE is designed to adapt to individualized needs based on each veteran's performance. The volunteer training consists of weekly sessions lasting 90 minutes each and occurring at area SPCA facilities. The logistics of the training sessions will be facilitated by study staff, with SPCA animal behaviorists and professionals conducting the training program identical to the program that they use for their general volunteer training. During volunteer sessions, the veteran learns behavioral techniques for training non-aggressive dogs through didactic instruction followed by demonstration and supervised practice. The animal socialization component of the RESCUE volunteer sessions are comprised of the SPCAs current training program, which is designed developmentally such that early training focuses on general topics (safety, basic handling skills) and later training builds on previously learned skills through successive approximation within each individual's zone of proximal development.
Behavioral: Prolonged Exposure
All veterans will receive individualized, evidence-based prolonged exposure therapy. Foa's PE protocol will be used given consensus statements indicating that exposure therapy is currently the most appropriate psychotherapy for PTSD. Study therapists are already trained clinicians through the VA's PE certification process and will receive weekly supervision for all cases from the PI, who is a national Prolonged Exposure trainer.
Other Names:
  • PE
ACTIVE_COMPARATOR: PE+delayed RESCUE
