Examining the Psychological Measures and Feasibility of Recreational Trail Rides in Reducing Cravings for Addictive Substances among Veterans: A Replication Pilot Study.

INTRODUCTION: Equine-assisted services have been gaining popularity as complementary therapies for a variety of populations with a diversity of diagnoses. Interventions using equines might benefit the military Veteran population through building therapeutic alliance as well as reducing symptoms. This pilot observational study is primarily aimed to investigate safety, feasibility, and acceptability of equine-assisted services for Veterans with substance abuse disorders. It is the second pilot observational study, the first being completed in 2022. Secondary outcomes included recording the impact of trail riding on psychological measures among Veterans at a large Veterans Administration medical center. METHODS: The study included a total of 32 Veterans who participated in trail riding sessions from May 4, 2022 to August 31, 2022. The study utilized the Positive and Negative Affect Scale, Adult Hope Scale, and Craving Experience Questionnaire to assess changes in positive affect, negative affect, hope components, and substance craving. RESULTS: The results indicated significant reductions in negative affect and substance craving after the first session, with positive effects observed in subsequent sessions. However, demographic and diagnostic variables did not predict significant changes in psychological instruments. CONCLUSION: Overall, the study demonstrated that trail riding was a safe and feasible intervention and may have potential benefits for improving emotional well-being and reducing substance cravings among Veterans. It is recommended that future studies research mechanisms of action, as well as conduct more rigorous investigations, including controlled trials using larger sample sizes and longitudinal research, to best determine lasting effects of these types of complementary therapies.

A pilot observational study of horsemanship skills training for veterans with posttraumatic stress disorder.

OBJECTIVES: Pilot assessment of an equine-assisted services intervention for Veterans with posttraumatic stress disorder. DESIGN: Prospective cohort. SETTING: A large Veterans Administration healthcare system. INTERVENTION: Two sessions of instruction in horsemanship skills and two sessions of trail rides. MAIN OUTCOME MEASURES: Safety and feasibility of recruitment, retention, providing the intervention, and measuring outcomes, as well as acceptability of the intervention to the population studied were the main outcome measures. RESULTS: There were no injuries among the 18 participants, 6 staff, or 11 equines over the 3 months of the study. Eleven of 12 (92 %) planned intervention sessions were provided, with one being canceled due to weather. Out of approximately 1800 potential subjects, 21 were enrolled within three months and three dropped out before the first session. The mean number of sessions attended was 3 % and 52 % of participants completed all sessions. The mean PACES score for all sessions together was 109 (SD = 12), with a range of 50-126. Pre- to one-month post-intervention exploratory results indicated increased psychological flexibility (p = 0.008) and positive affect (p = 0.008) as measured by the Acceptance and Action Questionnaire II and the Positive and Negative Affect Scale, respectively as well as decreased PTSD (p = 0.001) and depressive symptoms (p = 0.017) as measured by the PTSD Checklist for DSM 5 and the Beck Depression Inventory, respectively. CONCLUSIONS: Results suggest the intervention can be conducted with minimal risk. Further, it was feasible to recruit participants as well as provide the intervention and measure exploratory outcomes. Session attendance and PACES scores indicate acceptability to the Veteran population. The exploratory results will provide sample size estimates for future randomized controlled studies of this intervention Future studies should plan for missed sessions due to weather and consider compensating subjects to enhance retention. Finally, this work provides preliminary evidence that this intervention, without a mental health treatment component, might benefit the mental health of Veterans with PTSD.

A Pilot Observational Study of Implementing an Equine-A ssisted Services Program Within a VA Medical Center Residential Substance Use Disorder Treatment Program.

INTRODUCTION: The aim of this observational pilot study was to assess the safety, feasibility, preliminary outcomes, and predictors of participant response as a result of implementing an equine-assisted intervention within a residential substance abuse treatment program at a large Veterans Administration medical center. A secondary aim was to evaluate psychological instruments for use in future, more rigorous studies. The overarching goal was to complete the necessary work to prepare for a large randomized controlled trial of this intervention for Veterans with addictive disorders. MATERIALS AND METHODS: Participants were 33 Veterans, 29 males and 4 females, who participated in one 4-hour session of combined equine-assisted learning and equine-assisted psychotherapy during an admission to a residential substance abuse treatment program. Preintervention and postintervention instruments were utilized to assess changes in affect, anxiety, and craving. Demographic and diagnostic variables were evaluated for the potential to predict outcomes. RESULTS: The intervention was safe and feasible to utilize as there were no adverse outcomes to patients, staff, or equines. The State-Trait Anxiety Inventory, Craving Experience Questionnaire, and Positive and Negative Affect Scale revealed preliminary findings of significant preintervention to postintervention decreases in anxiety, negative affect, and craving, as well as increased positive affect. Lastly, the presence or absence of a history of suicide attempts and/or suicidal ideation were predictive of some postintervention scores. CONCLUSION: While more rigorous studies are needed, these results indicate that the intervention evaluated in this study is safe and feasible to utilize for Veterans admitted to a residential substance abuse treatment program. Furthermore, preliminary outcomes suggest that this intervention, and perhaps other equine-assisted interventions, has the potential to be beneficial to Veterans with addictive disorders as well as those at risk of suicide. The psychological instruments used in this intervention appear to be appropriate for use in future investigations. Additionally, more rigorous studies are warranted, and this work provides the necessary first steps needed to proceed with those investigations.

A pilot observational study of recreational trail riding for Veterans with addictive disorders.

OBJECTIVES: The aim of study was to assess the safety, feasibility, and preliminary outcomes of recreational trail riding for Veterans with addictive disorders. DESIGN: This was an observational pilot study. SETTING: United States Veterans Health Care Administration Medical Center. Participants were 18 Veterans, 13 males and 5 females All had at least one addictive disorder, with most common being alcohol use disorder. INTERVENTION: A recreational trail ride of approximately two hours duration. MAIN OUTCOME MEASURES: Assessment of safety and pre- and post-intervention instruments, The State-Trait Anxiety Inventory, Craving Experience Questionnaire, Positive and Negative Affect Scale and Conner-Davidson Resilience Scale were utilized to assess changes in anxiety, craving, affect, and resilience, respectively. RESULTS: The intervention was feasible to utilize for the population studied. In addition, it was possible to conduct the rides in such a way as to minimize risk to participants and there were no serious adverse outcomes to patients, staff, or equines. However, there was one incident that had potential to cause injury. There were significant pre- to post-intervention decreases in anxiety, negative affect and craving as well as increased positive affect. There was not a statistically significant increase in resilience. CONCLUSIONS: These results indicate that recreational trail riding is, at least in some settings, feasible to utilize for this population. The safety assessment indicated that this intervention can be conducted in a manner such that risk can be mitigated. However, trail riding is a dangerous activity that can result in serious injury or death to participants. Thus, such activities should only be considered by programs that have the ability to implement stringent safety protocols. Preliminary outcomes suggest that this intervention has the potential to be beneficial to for Veterans with addictive disorders. Additional, more rigorous randomized, controlled studies are warranted.

Preliminary study of the contraceptive effect of a self-assembling intrauterine device (iUPODs) in mares maintained in a paddock with a fertile stallion.

There is an urgent need for practical methods of population control (i.e., contraception and/or sterilization) for free-roaming (i.e., "wild" or "feral") horses and burros on Western Public Lands in the United States. The objective of this study was to evaluate the contraceptive efficacy of a novel self-assembling three-part polymer-coated magnetic intrauterine device termed as an intrauterine POD (self-assembling; iUPOD) when there are natural breeding conditions when iUPOD use was managed by veterinary professionals with no prior experience with the device. Six mares were administered an iUPOD and were then housed continuously with a fertile stallion for 91 days. The intrauterine POD retention and contraceptive efficacy were 100%. Two mares had prolonged corpus luteum function (for 37 and 91 days) immediately after iUPOD placement. For the estrous cycles of the other mares, the duration of diestrus was 7.8 ± 2.7 days (mean ± S.D.). Four of the mares (67%) became pregnant when in a paddock with the same stallion the year after iUPOD removal. These results are encouraging for use of the iUPOD as a practical and reversible method of fertility control in free-roaming horses and burros.

Equine-Assisted Activities and Therapies for Veterans With Posttraumatic Stress Disorder: Current State, Challenges and Future Directions.

Posttraumatic stress disorder is common among military Veterans. While effective treatments exist, many Veterans either do not engage in treatment or fail to achieve full remission. Thus, there is a need to develop adjunctive complementary interventions to enhance treatment engagement and/or response. Equine-assisted activities and therapies (EAAT) are one category of animal assisted interventions that might serve this function. The aim of this article is to review the current state and challenges regarding the use of EAAT for Veterans with PTSD and provide a roadmap to move the field forward. EAAT hold promise as adjunctive complementary interventions for symptom reduction among Veterans with PTSD. Additionally, there is evidence that these approaches may enhance wellbeing in this population. At this time, many gaps in the literature exist and rigorous randomized controlled trials are needed before definitive conclusions can be drawn. The authors of this work provide recommendations as a roadmap to move the field forward. These include standardizing the EAAT nomenclature, focusing mechanism of action studies on the human-horse bond using biological metrics and using a standardized intervention model across studies.
