Detailed Description
The EAP program will span over the duration of 5 weeks, each week having a 1-hour session. 50 minutes will be allocated to interacting with the horses and the activities while the remaining 10 minutes will be allocated to the clinical processing of the behavior, thoughts and emotions that are observed during the session. This processing will be guided by trained therapists who hold the relevant qualifications (i.e. equine-assisted psychotherapy certification). 2 horses (an Oldenburg and a pony, aged 19 and 14 respectively), 2 therapists, and 2 experienced horse handlers will be present throughout the sessions. Each 1-hour session will consist a maximum of 8 participants that will be split into two groups of 4 such that 1 horse, 1 therapist and 1 experienced horse handler are attached to them.
The design of the experiment will be a single-blind Randomized Controlled Trial. Participants will be told that this study aims to investigate the therapeutic effects of two different EAP programs (either watching video clips related to horses or actual interactions with horses) and that they will be randomly assigned to either one. In actuality, participants are randomly assigned to either an intervention group, an active-control group or a placebo-control group. 3 time points of data collection are measured throughout the 5-week duration - t1 before the 1st session, t2 after the 3rd session, and t3 after the final session. All participants will go through the same questionnaire administered at each time point during the 5-week duration regardless of their assigned group. Participants in the intervention group will go through the 5-week EAP program consisting of the clinical processing following some activities found in EAP manuals. Participants in the active-control group will undergo a 5-week program that only involves interactions with horses without any clinical input (i.e. commonly coined as animal-assisted activities). Participants in the placebo-control group will undergo a 5-week movie screening of 1 hour each session that is related to horses in the lab.
Participant recruitment will begin as soon as possible once approval has been given and should not take longer than 2 weeks to recruit a total of 120 undergraduate students from both NUS and NTU.
The 5-week intervention program will be briefly structured as such:
Session 1: Introduction to grooming and horse safety This introductory session is aimed at getting participants to be familiar with the safety features when working with these horses as well as to be attentive to the warning cues that horses display that is indicative of their mood. Once that has been briefed, participants will be taught how to groom the horse as part of learning natural horsemanship skills. These includes brushing and cleaning the hooves of the horse.
Session 2: Review of grooming, learning to put on halter and leading the horse The second session is built upon the previous session in that reviews of grooming and horse safety will continually be surfaced throughout the program as such lessons is always an ongoing process. On top of that, participants will be taught how to put on a halter on the horse and to lead the horse. The session ends with a modified activity called Catch and Release which allows participants to have personal interaction with the horse.
Session 3: Review of grooming and Give-and-Take The third session is more focused on the importance of proper communication as this helps convey the investigators intentions across with greater accuracy while still remaining respectful and mindful of the other party on the receiving end. After the grooming segment, participants will engage in an activity called Give-and-Take which work improving communication in a non-verbal manner only through the string they are provided with to guide the horse.
Session 4: Review on grooming and Life's Little Obstacles This session is aimed at utilizing participants' critical thinking skills to achieve the objective of the activity. This is meant to push participants' out of their comfort zones which could bring about feelings of frustration and worry that can be processed after the activity is over. The activity that is meant to create such a roadblock is the Life's Little Obstacles whereby participants are told to make the horse jump over a low obstacle with multiple restrictions.
Session 5: Review on grooming, Equine Billiards, and closing This final session is aimed at utilizing participants' problem-solving skills through the use of non-verbal communication. This is done using the Equine Billiards activity whereby the lessons learnt from previous sessions would culminate in this one task. Following the processing of the activity after it ends, the therapy team and participants would gather in a circle for the program closure to integrate whatever they have learnt from the past 5-weeks.
GPower 3.1 was used to calculate an appropriate sample size for a medium effect size of 0.15, power at 0.95 and alpha error probability at 0.05. For a multiple linear regression analysis with 2 tested predictors and total number of 4 predictors, the calculation yielded a total sample size of 119. This number was rounded up to 120.
All data will be analyzed using SPSS version 22. Some potential analyses include multiple linear regression, ANCOVAs and their respective post-hoc t-tests, paired-sample t-tests to demonstrate significant changes between pre and post intervention groups, and PROCESS Macro for the mediator analysis.

Arms and Interventions

Intervention / Treatment |
---|---|
EXPERIMENTAL: Intervention Group
Participants in the intervention group will go through the 5-week EAP program consisting of the clinical processing following some activities found in EAP manuals.
|
Equine-Assisted Psychotherapy (EAP) involves working on the psychological goals set between the client and the mental health professional.
This is done through the experiential interactions between the clients and the horse.
This experiential aspect is vital as it allows clients to process the emotions, thoughts and behaviors that were expressed during sessions with the horse.
Other Names:
Simple interactions with the horses that does not necessarily involve any goals being set between the client and the personnel handling the session.
These can involve activities such as grooming or petting of the horse.
|
ACTIVE_COMPARATOR: Active-control group
Participants in the active-control group will undergo a 5-week program that only involves interactions with horses without any clinical input (i.e.
commonly coined as animal-assisted activities).
|
Simple interactions with the horses that does not necessarily involve any goals being set between the client and the personnel handling the session.
These can involve activities such as grooming or petting of the horse.
|
PLACEBO_COMPARATOR: Placebo-control group
Participants in the placebo-control group will undergo a 5-week movie screening of 1 hour each session that is related to horses.
|
This group will only be watching movies related to horses and they are told that this is another form of EAP even though this is not the case.
This type of intervention has not been known to provide any therapeutic effect relevant to the study and thus is used as the placebo-control.
