Intervention / Treatment |
---|---|
No Intervention: Treatment as Usual (TAU)
|
|
Experimental: Equine Therapy
|
Aim 1: Six session equine interventions.
Intervention will be provided one day per week for four weeks.
During the first two weeks, each intervention day with consist of two sessions with a lunch break in between.
Weeks four and five consist of one trail riding session per intervention day followed by lunch.
Each session will be approximately 1.5 hours in length.
Sessions 1-4 will occur at the USU Equine Education Center, and session 5-6 will occur on local trails.
Optional transportation for participants will be provided from the VA to the intervention site.
|
Experimental: Therapeutic Horsemanship Program
|
Aim 2: Therapeutic Horsemanship program utilizes the USU Pathways to Horsemanship model and covers levels of equestrian training from basic groundwork to more advanced riding techniques.
Training occurs in a three or six-session format with once weekly sessions over three or six weeks.
Mindfulness and mindful self-compassion training may be included.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Mean Difference in Acceptance and Action Questionnaire-II (AAQII) among the Equine Therapy + TAU cohort compared to the TAU only cohort and for Horsemanship Skills Training Program
Time Frame: through study completion, an average of 2 years
|
AAQII measures psychological flexibility.
The total AAQII score can range from 7 to 49, with higher values indicating greater psychological inflexibility.
Mixed Effect Modeling will be used for the analyses.
Within and between group analyses of pre- to post-intervention psychological instrument and service utilization data will be conducted to determine whether outcomes are associated with program participation.
We'll estimate the outcome at multiple time points: pre-intervention, post-intervention for selected or all sessions, and post-intervention.
|
through study completion, an average of 2 years
|
Heart Rate (HR) Indices
Time Frame: through study completion, an average of 2 years
|
To determine correlations between physiological responses of the rider and horse, the following heart rate (HR) indices will be computed: Mean HR, standard deviation of the beat-to-beat intervals (SDRR) and the root mean square of successive beat-to-beat differences (rMSSD).
Both SDRR and rMSSD are measures of HR variability and reflect shifts between sympathetic (e.g., decrease in HR variability) or parasympathetic (e.g., increase in HR variability) drive.
These measures will be taken during each equine intervention session.
|
through study completion, an average of 2 years
|
Mean Difference in Positive and Negative Affect Scale (PANAS) among the Equine Therapy + TAU cohort compared to the TAU only cohort and for Horsemanship Skills Training Program
Time Frame: through study completion, an average of 2 years
|
PANAS measures short-term positive and negative emotions.
The total PANAS-C score can range from 12 to 60 for the positive affect (PA) scale, with higher values indicating greater PA.
Similarly, the score range from 15 to 75 for the negative affect (NA) scale, with higher values indicating greater NA.
Mixed Effect Modeling will be used for the primary analyses.
Within and between group analyses of pre- to post-intervention psychological instrument and service utilization data will be conducted to determine whether outcomes are associated with program participation.
We'll estimate the primary outcome at multiple time points: pre-intervention, post-intervention sessions, and post-intervention.
|
through study completion, an average of 2 years
|
Mean Difference in Physical Activity Enjoyment Scale (PACES) for Equine Therapy + TAU cohort compared to the TAU only cohort and for Horsemanship Skills Training Program
Time Frame: through study completion, an average of 2 years
|
PACES measures enjoyment of activity.
The total PACES score can range from 18 to 126, with higher values indicating greater enjoyment.
Mixed Effect Modeling will be used for the primary analyses.
Within and between group analyses of pre- to post-intervention psychological instrument and service utilization data will be conducted to determine whether outcomes are associated with program participation.
We'll estimate the outcome after the intervention sessions and post-intervention.
|
through study completion, an average of 2 years
|
Mean Difference in Posttraumatic Stress Disorder Checklist (PCL) for Equine Therapy + TAU cohort compared to the TAU only cohort
Time Frame: through study completion, an average of 2 years
|
PCL measures PTSD symptoms.
The total PCL score can range from 17 to 85, with higher values indicating greater PTSD symptoms.
Mixed Effect Modeling will be used for the primary analyses.
Within and between group analyses of pre- to post-intervention psychological instrument and service utilization data will be conducted to determine whether outcomes are associated with program participation.
We'll estimate outcome post-intervention sessions and post-intervention.
|
through study completion, an average of 2 years
|
Mean Difference in Beck Depression Inventory (BDI) for Equine Therapy + TAU cohort compared to the TAU only cohort
Time Frame: through study completion, an average of 2 years
|
BDI measures depressive symptoms.
The total BDI score can range from 0 to 63, with higher values indicating greater depressive symptoms.
Mixed Effect Modeling will be used for the primary analyses.
Within and between group analyses of pre- to post-intervention psychological instrument and service utilization data will be conducted to determine whether outcomes are associated with program participation.
We'll estimate outcome post-intervention sessions and post-intervention.
|
through study completion, an average of 2 years
|
Mean Difference in Quality of Life Enjoyment and Satisfaction Questionnaire - Short Form (Q-LES-Q-SF) for Horsemanship Skills Training Program and for Equine Therapy + TAU cohort compared to the TAU only cohort
Time Frame: through study completion, an average of 2 years
|
Q-LES-Q-SF measures quality of, and satisfaction with, life.
The total Q-LES-Q-SF score can range from 14 to 70, with higher values indicating greater satisfaction.
Mixed Effect Modeling will be used for the primary analyses.
Within and between group analyses of pre- to post-intervention psychological instrument and service utilization data will be conducted to determine whether outcomes are associated with program participation.
We'll estimate outcome post-intervention sessions and post-intervention.
|
