Equine-Assisted Therapeutic Interventions Among Individuals Diagnosed With Schizophrenia. A Systematic Review

Experiences of a Therapeutic Equine-Assisted Group Intervention for People with Common Mental Disorders on Sick-Leave

Common mental disorders such as anxiety, depression and stress-related disorders are increasing worldwide, resulting in long-term sick leave and lower quality of life. Traditional treatment is often insufficient to facilitate the recovery process, and the need for holistic interventions that enable successful recovery is evident. Equine-assisted interventions have shown promising results in health promotion among people with mental disorders, and further research is needed to implement them within the range of available care. The aim of the study is therefore to describe experiences of a therapeutic equine-assisted group intervention for people with common mental disorders on sick leave. The study has a descriptive qualitative design with an inductive approach. Ten participants with common mental disorders on sick leave were interviewed after participating in a 12-week equine-assisted intervention and the data were analysed with conventional content analysis. The analysis generated the overall theme "The equine-assisted group intervention facilitates recovery," which summons the four categories "The environment of the horses contributes to relaxation and an ability to be in the present," "The presence of the horses facilitates supportive relationships in the group," "Interplay with the horses entails physical activity and bodily improvements" and "Emotional interactions with the horses strengthen inner power." In conclusion, equine-assisted interventions have the potential to facilitate recovery for people with common mental disorders by providing relaxation, promoting the ability to be in the present, cultivating supportive relationships and providing physical activity and bodily improvements as well as emotional interactions that strengthen the participants' inner power.

Potential Mechanisms of Action and Outcomes of Equine-Assisted Services for Veterans with a History of Trauma: A Narrative Review of the Literature

Equine-assisted services (EASs) are being increasingly used as complementary interventions for military veterans who have experienced trauma. However, there is limited evidence of benefit for this population and almost no literature describing the desired potential outcomes and possible mechanisms of action. The aim of this article is to address these gaps by reviewing the extant literature of animal-assisted interventions in general, and equine-assisted services in particular, with the goal of providing guidance for future investigations in the field. Currently, the field is in the early stage of scientific development, but published results are promising. Interventions that enhance treatment compliance and/or outcomes could benefit this population. Preliminary results, reviewed herein, indicate that EAS interventions might benefit the military veteran population by enhancing treatment engagement and therapeutic alliance, as well as by contributing to symptom reduction and resulting in various transdiagnostic benefits. It is recommended that future studies include exploration of potential beneficial outcomes discussed herein, as well as investigate suggested mechanisms of action.

Dog-assisted interventions for adults diagnosed with schizophrenia and related disorders: a systematic review

Background

Many individuals diagnosed with schizophrenia and related disorders experience insufficient symptom relief from currently available treatment options. Researching additional venues should be prioritized. This systematic review, designed in accordance with PRISMA, examined the effect of targeted and structured dog-assisted interventions as a supplementary treatment.

Methods

Randomized as well as non-randomized studies were included. Systematic searches were conducted in APA PsycInfo, AMED, CENTRAL, Cinahl, Embase, Medline, Web of Science, and in several sources covering "gray" (unpublished) literature. In addition, forward and backward citation searches were performed. A narrative synthesis was conducted. Quality of evidence and risk of bias were assessed in accordance with GRADE and RoB2/ROBINS-I criteria.

Results

12 publications from 11 different studies met eligibility criteria. Overall, studies showed diverging results. General psychopathology, positive and negative symptoms of psychosis, anxiety, stress, self-esteem, self-determination, lower body strength, social function, and quality of life were among the outcome measures with significant improvement. Most documentation for significant improvement was found for positive symptoms. One study indicated significant deterioration of non-personal social behavior. The risk of bias was high or serious for most of the outcome measures. Three outcome measures were associated with some concerns regarding risk of bias, and three with low risk of bias. Quality of evidence was graded low or very low for all outcome measures.

Conclusions

The included studies indicate potential effects of dog-assisted interventions for adults diagnosed with schizophrenia and related disorders, mostly beneficial. Nevertheless, low number of participants, heterogeneity, and risk of bias complicate the interpretation of results. Carefully designed randomized controlled trials are needed to determine causality between interventions and treatment effects.

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.

The Effects of an Equine-Assisted Therapeutic Intervention on Well-Being in Persons Diagnosed with Schizophrenia. A Pilot Study

The process of personal recovery among persons diagnosed with schizophrenia may be facilitated through innovative health promotion interventions targeting multidimensional aspects of subjective well-being. The current pilot study aims to test the use of self-rated questionnaires as a means of evaluation of the effects of an equine-assisted intervention for persons diagnosed with schizophrenia. Twenty adults diagnosed with schizophrenia were offered a 12-week EAT intervention performed six times once every 14 days by a licensed mental health nurse. Two validated self-rated questionnaires, HSCL-25 and SHIS were used as outcome measurements at baseline and at post-treatment, additionally the self-rated questionnaire PANAS was completed twice a week starting 1 week before the 12 week-EAT intervention. Only six of the 20 participants managed to complete the validated questionnaires. Despite the low response rate of approximately 30%, a significant difference was found between pre and post scores for positive affect and well-being. Effect sizes, ranging from small to large for pre-to-post treatment scores indicated less depression and anxiety, more positive affect, less negative affect, and reinforced well-being. Results suggest that EAT interventions may have beneficial effects among persons diagnosed with schizophrenia and that a varied range of research methods are needed to create a solid evidence base for EAT interventions intended for the target group.

Evaluation of stress markers in horses during hippotherapy sessions in comparison to being ridden by beginners

Hippotherapy has been used for decades and its benefits to human patients have largely been proven, whether being applied to those with physical or mental disabilities. There have been a plethora of animal welfare studies recently, pertaining especially to ridden horses. This study aimed to investigate stress markers in horses during hippotherapy sessions to address the ethical considerations raised by using horses for therapy. A ridden stress ethogram was established and validated specifically for this study via subjective observation and video recording of a ridden session involving intermediate-level riders. The experiment entailed eight healthy horses undergoing two ridden sessions on separate days, one with disabled riders and one with beginners. Several parameters associated with physiological responses to stress were evaluated at rest, such as heart rate, plasma adrenocorticotropic hormone [ACTH], serum and salivary cortisol. These parameters as well as the behavioural stress score from the ethogram scale were measured during both sessions. No significant differences were found between heart rate, plasma ACTH, and stress scores. Serum and salivary cortisol were significantly lower during the hippotherapy session than during the session with beginners. The current study found no evidence of compromised welfare when horses were used as a therapeutic aid during hippotherapy sessions compared to their usual ridden activity. Although these results indicate that hippotherapy may be ethically justified as it benefits humans without causing harm to the horses, the present study was small, and the results should be interpreted with caution.

Relatives’ experiences of an equine-assisted intervention for people with psychotic disorders

Purpose

The aim of this study was to describe relatives’ experiences of an equine-assisted intervention for people with psychotic disorders.

Methods

The study has a qualitative and descriptive design. Ten semi-structured interviews were performed with relatives of people with a psychotic disorder who had participated in an equine-assisted intervention. A conventional content analysis was used to analyse the data.

Result

The overall category “Being with the horses strengthens health capabilities” summarizes the four identified subcategories “The horses contribute to a context with a common focus”, “Interaction with the horses enhances self-confidence and motivation”, “The interplay with the horses nurtures positive emotions” and “Being with the horses encourages physical activity”.

Conclusions

The result of this study contributes to the growing body of research about the potential outcomes of equine-assisted interventions. The result also indicates that equine-assisted interventions may improve health capabilities among people with psychotic disorders. The generated knowledge may be useful in mental health services when developing equine-assisted interventions.

A pilot observational study of a psychotherapy incorporating equines resiliency intervention for staff at a large medical center

BACKGROUND

and purpose: Stress and burnout among healthcare workers are significant public health concerns. The primary aim of this pilot study was to conduct preliminary assessments of safety, feasibility, and participant satisfaction with a psychotherapy incorporating equines (PIE)-based resiliency intervention for healthcare workers. The overarching goal was to lay the groundwork for future, more rigorous investigations. Lastly, a very preliminary assessment of using the Acceptance and Action Questionnaire II (AAQII) to assess for changes in psychological flexibility (PF) associated with PIE was conducted.

MATERIALS AND METHODS

Thirty-seven staff members from a medical center participated in a 4-h PIE-based resiliency retreat. Pre- and post-intervention instruments were utilized to assess participants' self-perception of physical and psychological health (PROMIS Global Short Form) and enjoyment of (Physical Activity Enjoyment Scale) and satisfaction with (Client Satisfaction Questionnaire) the intervention, as well as changes in PF (AAQII).

RESULTS

There were no adverse effects on participants, staff, or equines. Preliminary results suggested that the intervention was perceived as enjoyable by participants. However, the intervention was not fully utilized. Finally, there was a significant (p = 0.02) pre-to post-intervention change in AAQII scores.

CONCLUSION

This study provides a foundation for future rigorous studies of PIE-based resiliency interventions for medical staff. Given the limitations of this pilot work, firm conclusions cannot be drawn regarding safety and feasibility. However, the preliminary results suggest that future studies of this intervention are warranted and that the AAQII may be a useful instrument to assess for possible changes in PF.

The Role of the Horse in an Equine-Assisted Group Intervention-as Conceptualized by Persons with Psychotic Conditions

Adopting positive health interventions is necessary to promote self-image, improve well-being, support meaningful social interaction and reduce loneliness, with benefits for psychological and physical health for persons with psychotic conditions. Raised awareness of the potential benefits of involving horses in these kinds of interventions is warranted. Thus, the aim of this study was to explore the role of the horse in equine-assisted interventions (EAI) as conceptualized among persons with psychotic conditions. Interviews were conducted with eight persons with psychotic conditions who had participated in an EAI, and data were analyzed following conventional qualitative content analysis. The results illustrate how the horse united the group and facilitated personal maturity both at a group level and at a personal level. In the group the horse facilitated interaction and became a healthy and normal topic of discussion. The interaction between the horse and others helped the participants to become aware of and reflect on behaviors of oneself and of others. At an individual level, the horse helped to develop participants' identities and growth by offer mutual friendship. With its size and calming way of being, the horse evoked a healing power among participants who identified characteristics of themselves in the horse. Through its clear body language and communication, the horse facilitated personal maturity and development among the participants that would not have occurred without the horse's presence.

The Role of Animal Ownership for People with Severe Mental Illness during the COVID-19 Pandemic: A Mixed-Method Study Investigating Links with Health and Loneliness

Research has reported the benefits of companion animals for people with severe mental illness (SMI). However, this evidence base is fragmented and unclear. The COVID-19 pandemic presents an opportunity to explore the role of companion animals in the context of social distancing and isolation measures for people with SMI. Therefore, we aimed to investigate the links between mental and physical health and animal ownership in people with SMI and to explore animal owners’ perceptions related to human–animal interactions during the pandemic restrictions. A survey was conducted with a previously assembled cohort of individuals with SMI in the UK. The survey included previously validated and new bespoke items measuring demographics, and outcomes related to mental and physical health, and human–animal interactions. The survey also included a question inviting free-text responses, allowing participants to describe any experiences of their human–animal relationships during the pandemic. Of 315 participants who consented to participate, 249 (79%) completed the survey. Of these, 115 (46.2%) had at least one companion animal. Regression analyses indicated that animal ownership was not significantly associated with well-being and loneliness. However, animal ownership was associated with a self-reported decline in mental health (b = 0.640, 95% CI [0.102–1.231], p = 0.025), but no self-reported change in physical health. Thematic analysis identified two main themes relating to the positive and negative impact of animal ownership during pandemic restrictions. Animal ownership appeared to be linked to self-reported mental health decline in people with SMI during the second wave of the pandemic in the UK. However, the thematic analysis also highlighted the perceived benefit of animal ownership during this time. Further targeted investigation of the role of human–animal relationships and the perceived human–animal bond for human health is warranted.

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.

Positioning Psychiatric and Mental Health Nursing as a Transformative Force in Health Care

From the perspective of psychiatric and mental health nurses in Sweden, this discussion paper aims to position psychiatric and mental health nursing as a transformative force contributing to enforcing person-centered values and practices in health care. We argue the potential impact of psychiatric and mental health nursing on service user health and recovery, nursing student education and values, and the organization and management of health care. Psychiatric and mental health nursing is discussed as a caring, reflective, and therapeutic practice that promotes recovery and health. Implications for nursing education, research, management, and practice are outlined.

A Study Exploring the Implementation of an Equine Assisted Intervention for Young People with Mental Health and Behavioural Issues

This paper presents the findings from a study of an equine assisted intervention (EAI), which is currently referred over 150 predominantly young people with mental health and behavioural problems each year. The young people are referred to this intervention when other services such as Child & Adolescent Mental Health Services (CAMHS) are not effective. Performing an exploratory study of implementation may be indicated when, there are few previously published studies or existing data using a specific intervention technique. This study showed some positive changes for participants across eight dimensions including; assertiveness, engagement with learning, calmness, planning, taking responsibility, empathy, communication and focus and perseverance. The equine intervention literature has shown mixed results across a variety of study designs and target groups, in terms of the gold standard of evidence, randomised controlled studies however the evidence currently is very limited. This study used a non-randomised sample, no control group and an unstandardised measurement filled out by those who refer young people to the intervention (social workers and teachers). The outcomes however from this exploratory study would suggest that a randomised control trial may be warranted and achievable.
