Substance use disorder treatment retention and completion: a prospective study of horse-assisted therapy (HAT) for young adults

Being in a meaningful context. Nature and animal-assisted activities as perceived by adults with autism

INTRODUCTION

Animal-assisted and nature-based interventions in psychosocial treatment for various groups of clients have been studied internationally. However, there is little knowledge about how young adults with autism experience participation in such types of interventions. This clinical study aimed to describe the feasibility of animal-assisted and nature-based activities on a farm as a complementary intervention for young adults with autism and social withdrawal.

METHODS

The participants were aged 18-30 years, diagnosed with autism and social withdrawal, with no organised occupation during the previous year. Eleven of 13 participants completed a 12-week intervention in small groups. They took part in interviews before and after, which focused on their current life situation and expectations about, and experiences of the intervention. The feasibility was described in terms of participants' characteristics, attendance, and their experiences of participating in the activity. Data were analysed with descriptive statistics and qualitative content analysis.

CONSUMER AND COMMUNITY INVOLVEMENT

The intervention was formed in collaboration with participating supervisors, ordinary clinical staff, and a young woman with a user perspective.

FINDINGS

The level of feasibility was found to be high. The mean participation rate during the activity days was 75% and varied from 50 to 100%. The analysis of the participants' experiences from the activity generated three categories, "Being in a meaningful context", "Creating a comfort zone" and "Developing structure in everyday life", and each of these included sub-categories.

CONCLUSION

The main categories revealed a dynamic process based in meaningfulness, comfort and structure in everyday life. The positive experiences of undemanding activities, emotional relationships and non-verbal communication with the horses were prominent and might facilitate the development of social interaction. However, the intervention's timeframe of 12 weeks was experienced as too short for long-lasting change.

A Pilot Replication Study of Implementing an Equine-Assisted Services Program Within a VA Residential Substance Use Disorder Treatment Program

INTRODUCTION

Veterans have high rates of substance use disorders and other mental health conditions including post-traumatic stress disorder. Effective treatments for these conditions exist; however, high attrition rates and residual symptoms after completing treatment are common. Complementary treatment approaches could enhance treatment engagement and/or response among this population. We previously reported a study of one such intervention, an equine-assisted learning, and psychotherapy incorporating horses intervention provided to veterans admitted to a Veterans Health Care Administration residential substance abuse treatment program. The first aim of this study was to replicate the previous study assessing the safety, feasibility, and preliminary outcomes of this intervention. The second aim was to examine the effect of participants attending multiple intervention sessions.

MATERIALS AND METHODS

Participants were 94 veterans who participated in one to six sessions of a 3-4-hour program consisting of both equine-assisted learning and psychotherapy incorporating horses. Pre- and post-session administration of the Positive and Negative Affect Scale, State-Trait Anxiety Inventory, and Craving Experience Questionnaire was utilized to assess changes in affect, anxiety, and craving. Wilcoxon signed-rank or paired two-tailed t-tests were utilized for pre- to post-session comparisons of the outcome measures for sessions 1-4. Generalized linear mixed-effects (GLME) models were constructed to determine the impact of dosage. GLME models were constructed to determine the impact of dosage.

RESULTS

As with our previous study, the intervention was safe and feasible to utilize for this population. There were statistically significant pre- to post-session improvements, with medium-to-large effect sizes, for sessions 1-3 for negative affect and sessions 1 and 2 for positive affect, anxiety, and craving. The GLME models revealed no statistical significance for any of the predictors.

CONCLUSIONS

Taken together, this study and our previous investigation of this equine-assisted services intervention suggest that it is safe and feasible to utilize for veterans admitted to a residential substance abuse treatment program and we have now found short-term benefits in two separate studies. Thus, a randomized controlled trial of this intervention is warranted to demonstrate cause and effect and determine whether longer-term benefits are associated with the intervention. The finding that there was no additional benefit from attendance at more than two intervention sessions suggests that dose-response relationship studies of equine-assisted services interventions for veterans are needed.

Does Equine Interaction Facilitate Emotional Safety and Learning for College Students within an Agricultural-Based Classroom?

Effective teaching requires an educational environment that promotes learning, and yet, developing such an environment can be challenging within today's agricultural-based classroom for educators due to the trend to a more virtual teaching format and less hands-on learning. Animal interaction, particularly equine activities, has been shown to assist educators in the development of an emotionally safe environment for promoting learning. However, research is lacking as to whether the interaction with the animal needs to be direct or indirect within the collegiate educational environment to observe benefits. Therefore, the objective of this study was to determine the impact of equine interaction, both direct and indirect, within an educational environment on the emotional safety and learning for the college student within the agricultural-based classroom. Three course types were observed within the agricultural-based educational environment that included courses with no equine interaction (Group A) and courses with equine interaction, both direct (Group B) and indirect (Group C) interaction with the horse. Indirect interaction included items such as observation of equine handling via a video or gaining knowledge from reading online materials, but not engaging in direct, hands-on activities with the horse. Development of emotional safety within the students enrolled within these courses was measured using a self-reporting emotional safety evaluation. Due to the structure of the scale, a decrease in emotional safety indicated a positive change. Learning, both development of semantic and procedural memory, was measured using a student-completed knowledge examination and an instructor-completed skill evaluation, respectively. While significant improvement in emotional safety was not observed within any of the course types, a weak negative correlation was found between emotional safety and semantic memory for students enrolled in equine courses, both direct (R = -0.55, R2 = 0.28) and indirect (R = -0.25, R2 = 0.06) interaction, finding as emotional safety scores lowered to the ideal range that knowledge improved. In addition, students within equine courses showed semantic memory development in specific areas of equine sciences (Group B: Grooming/Tacking, p = 0.03; Group C: Equine Behavior, p = 0.04) and direct equine interaction resulted in development of equine-based procedural memory in all four skill areas measured within the study (p = 0.00). As such, learning is promoted through equine interaction, whether direct or indirect interaction, within the agricultural-based classroom, suggesting that both forms of equine interaction can be a valuable educational tool for the instructor within the collegiate setting.

An evaluation of the effect of equine-facilitated psychotherapy on patients with substance use disorders

Equine Facilitated Psychiatry and Psychology (EFPP) is a supportive non-pharmacological treatment program used in the treatment of patients with substance use disorder. The aim of this study was to evaluate a possible change in patient's health and health-related quality of life between the first and fourth session of the EFPP program using the Assessment of Quality of Life (AQoL) and the Health of the Nation Outcome Scales (HoNOS). The Human-Animal Interaction Scale (HAIS) and a 5-point Likert-type scale was used for an assessment of patient's mood in the experimental group. The study sample included 57 patients (39 in experimental group with EFPP and 18 without EFPP program) with substance use disorders hospitalized in the psychiatric hospital. Comparing the initial and final patients scores in the experimental group, there was a significant positive shift in three of the four domains of the HoNOS scale and in seven of the eight dimensions of the AQoL scale. HAIS significantly increased (p <0.001) in time as well as patient´s mood after every session and in long time perspective. Based on these results, we can assume that the EFPP might be one of the successful programs which may improve patient´s mood and social interactions in substance use disorders.

Equine-assisted services for individuals with substance use disorders: a scoping review

The implementation of equine-assisted services (EAS) during treatment for psychological disorders has been frequently documented; however, little is known about the effect of EAS on outcomes for populations with substance use disorder (SUD). The purpose of this scoping review was to synthesize existing literature reporting the effects of EAS when incorporated into SUD treatment. This review followed guidelines in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist for scoping reviews. A search of four databases (MEDLINE/PubMed, PsycINFO, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Academic OneFile) identified studies reporting quantitative and/or qualitative data for an EAS intervention that was implemented among a population receiving treatment for and/or diagnosed with SUD. Of 188 titles, 71 underwent full-text assessment and six met inclusion criteria. Three additional articles were identified through other sources. Quantitative data suggested a potential positive effect of EAS on SUD treatment retention and completion as well as participants' mental health; however, studies were limited by small sample sizes. Qualitative data indicated that in addition to participants developing bonds with the horses and perceiving EAS as welcomed breaks from traditional treatment, they experienced increased self-efficacy, positive emotional affect, and SUD treatment motivation. Due to methodological limitations and an overall dearth of available studies, the effectiveness of EAS as adjuncts to SUD treatment is inconclusive. Additional research is necessary before supporting broad implementation of EAS as adjuncts to SUD treatment.

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.

Investigating interventions that lead to the highest treatment retention for emerging adults with substance use disorder: A systematic review

BACKGROUND AND AIMS

Emerging adults (age 18-25) have the highest rate of substance use disorders (SUD) and often drop out of treatment earlier than those age twenty six or older. In order to increase treatment retention in emerging adults, there needs to be a better understanding of which SUD treatment interventions work best for this population. The purpose of this systematic review was to evaluate treatment interventions for emerging adults with SUD and identify which interventions show promise for retention in treatment.

METHODS

Following the PRISMA guidelines, Medline, PsycInfo, CINAHL (all via EBSCO), and Embase were systematically searched for articles that evaluated treatment interventions for emerging adults with SUD. From here, the authors identified treatment interventions that showed promise for retention in treatment.

RESULTS

Nine studies were included. The main findings indicate (1) behavioral therapy such as cognitive behavioral therapy and contingency management for cannabis and alcohol use disorders, or (2) cognitive behavioral therapy paired with opioid-agonist-therapy for opioid use disorder demonstrate the most promise for retention in treatment.

CONCLUSION

The interventions identified that show promise for emerging adults was similar to studies evaluating interventions for all ages. Given that retention rates are often lower in emerging adults despite the application of the full range of effective adult treatments, this review suggests they may require something different. While further studies are warranted to determine with more certainty what works best to keep emerging adults in treatment, some tentative suggestions are included.

Equine-assisted psychotherapy with traumatized couples-Improvement of relationship quality and psychological symptoms

Many traumatised individuals suffering from deployment related PTSD report severe problems in their relationships. Up until now, the therapeutic interventions used by the German Armed Forces have rarely targeted these problems through the integration of partners. For this reason, a Program designed specifically for couples was developed. In this prospective study equine-assisted psychotherapy was applied to soldiers and their spouses. The study population consisted of n = 36 couples, divided in n = 20 therapy group with a inpatient equine-assisted intervention and a 16-couples control group. After the intervention, numerous significant improvements occurred in the therapy group in the areas of current, somatic and communication problems, depressive symptoms and partnership quality but not in the control group. PTSD was reduced significantly on the sub-scale associated with negative thoughts. These results show that the intervention is an effective way to improve partnership quality and reduce the stressors that the partners of afflicted service members face.

Psychodynamic Based Equine-Assisted Psychotherapy in Adults with Intertwined Personality Problems and Traumatization: A Systematic Review

The growing field of equine-assisted psychotherapy (EAP), a subfield of animal-assisted psychotherapy (AAP), needs theoretically-based clinical studies. This systematic review examines the existing clinical studies in adult populations on psychodynamic psychotherapy combined with equine-assisted psychotherapy. An electronic database search was divided in two studies to identify publications on 1) EAP combined with psychodynamic psychotherapy and 2) EAP combined to personality problems and traumatization in order to compile studies by population, intervention, outcome and therapeutic assets. Study 1 revealed no relevant clinical studies on EAP with a psychodynamic background with an adult population. Study 2 revealed 12 publications to review predominantly addressing veterans with PTSD. The methodological limitations of most of the studies restrain the overall findings on outcome. However, overall positive effects for EAP, specifically on its experiential features and on finding interpersonal trust for patients, can be discerned. There is an apparent need for clinical studies meeting methodological standards on psychodynamic underpinned EAP methodologies in adults with intertwined personality problems and traumatization.

Complementary horse-assisted therapy for substance use disorders: a randomized controlled trial

BACKGROUND

Treatment completion is the greatest challenge for the treatment of substance use disorders (SUDs). A previous investigation showed that complementary horse-assisted therapy (cHAT) was associated with higher retention in treatment and completion than standard treatment alone. This randomized controlled trial further explored the benefits of cHAT for patients with SUDs.

METHODS

Fifty patients in residential SUD treatment at the Department of Addiction Treatment, Oslo University Hospital, were randomly allocated to either cHAT (cHAT group) or treatment as usual alone (TAU-only group). The primary end-point was treatment completion. Secondary end-points were dropout, transfer to another treatment, and time in treatment.

RESULTS

The multinomial logistic regression analysis found no statistically significant association between intervention (cHAT) and treatment outcome (completion, dropout, transferred) among the 37 participants who were ultimately recruited to the study. Some unforeseen challenges were encountered in the study: a high number of subjects transferred to another treatment, variable attendance at cHAT sessions, and long temporary exits. Nevertheless, 44% of participants in the cHAT group completed their treatment, compared with 32% in the TAU-only group; this observation encourages further investigation in a larger sample.

CONCLUSIONS

Though no association was identified between cHAT and treatment retention or completion, our study may have been underpowered. Further work in a larger clinical population is needed; observational studies with repeated measures may also be useful for investigating whether cHAT increases retention in treatment or rates of completion, two important factors for successful SUD treatment. Trial registration The trial was registered and approved on 14 October 2011 by the Regional Committee for Medical and Health Research Ethics with registration number 2011/1642 and registered at ClinicalTrials.gov on 21 February 2013 with registration number NCT01795755.

The Nguudu Barndimanmanha Project-Improving Social and Emotional Wellbeing in Aboriginal Youth Through Equine Assisted Learning

Background: Recent statistics have painted a grim picture for Australia's Aboriginal youth, with reports of higher levels of almost every health indicator, including depression, sexual and emotional abuse, unemployment, and incarceration. Traditional western based therapies have proven to have limited effectiveness in engaging this group as they can often be culturally inappropriate. International studies have provided promising results using equine assisted learning, with a sound methodological basis underpinned by Indigenous ways of being and doing. In Australia Aboriginal people have strong historical ties to horses through their work on stations and were often considered some of the country's best horsemen and women. While equine assisted learning programs exist in Australia there are currently none catering specifically to Aboriginal youth, run and staffed by Aboriginal staff and provided in a culturally secure manner.

Aims: Alternative therapy for Aboriginal youth in the areas of grief, loss, and trauma, through an equine assisted learning program that focussed on self-concept, self-regulation, self-awareness, anxiety and depression, and sense of connectedness.

Methods: Participants (N = 270) aged 6–25 years old engaged in a minimum of 6-weeks of equine assisted learning. Each session was 45–50 min duration and occurred on a weekly basis. Sessions were undertaken individually, in pairs and in groups, depending on the needs of the participant and the focus of the session goals. Qualitative examination of the participants included photography to capture the lived experiences of the participants throughout the program. In addition an cultural and age appropriate adaptation of the Strength and Difficulties Questionnaire was trialed to track changes quantitively.

Conclusion: We observed improvements in self-regulation, self-awareness, and socialization skills, evident from the photography recording and the questionnaire data. In addition parent and/or caregiver and teacher reported changes in behavior, self-regulation, and socialization skills were recorded.

A Randomized Controlled Trial of Animal-Assisted Therapy as an Adjunct to Intensive Family Preservation Services

METHOD

Families referred by Child Protective Services ( M _{child age} = 6 years ± 4; M _{parent age} = 32 years ± 8.26) were individually randomized to experimental ( n = 14) or control ( n = 14) intervention. Family functioning outcomes were measured using the North Carolina Family Assessment Scale for Reunification.

RESULTS

All four targeted family functioning outcomes were significantly increased for participants who received animal-assisted therapy as an adjunct to intensive family preservation services ( n = 14) with medium to large effect sizes. These improvements were sustained in two of the subscales through discharge. No significant differences were measured for the distal clinical outcome of disposition of children at discharge.

CONCLUSIONS

Findings suggest that adding animal-assisted therapy as an adjunct can improve evidence-based clinical interventions aimed at enhancing the caregiving contexts of children.

A meta-analysis of dropout rates in acceptance and commitment therapy

Many psychotherapies, including cognitive behavioral therapy and acceptance and commitment therapy (ACT), have been found to be effective interventions for a range of psychological and behavioral health concerns. Another aspect of treatment utility to consider is dropout, as interventions only work if clients are engaged in them. To date, no research has used meta-analytic methods to examine dropout in ACT. Thus, the objectives of the present meta-analysis were to (1) determine the aggregate dropout rate for ACT in randomized controlled trials, (2) compare dropout rates in ACT to those in other psychotherapies, and (3) identify potential moderators of dropout in ACT. Our literature search yielded 68 studies, representing 4,729 participants. The weighted mean dropout rates in ACT exclusive conditions and ACT inclusive conditions (i.e., those that included an ACT intervention) were 15.8% (95% CI: 11.9%, 20.1%) and 16.0% (95% CI: 12.5%, 19.8%), respectively. ACT dropout rates were not significantly different from those of established psychological treatments. In addition, dropout rates did not vary by client characteristics or study methodological quality. However, master's-level clinicians/therapists (weighted mean = 29.9%, CI: 17.6%, 43.8%) were associated with higher dropout than psychologists (weighted mean = 12.4%, 95% CI: 6.7%, 19.4%). More research on manipulable, process variables that influence dropout is needed.

Young adults' reasons for dropout from residential substance use disorder treatment

Dropout from substance use disorder treatment is usually investigated and understood from a perspective of quantitative patient-related factors. Patients' own perspectives (user perspective) are rarely reported. This study, therefore, aimed to explore patients' own understanding of their dropout from residential substance use disorder treatment. The participants were 15 males and females, aged 19-29 years, who had dropped out of residential substance use disorder treatment at the Department of Addiction Treatment, Oslo University Hospital, Norway. Qualitative methodology with semistructured interviews was used to explore how the participants described their dropout and their reasons for doing so. Thematic analysis was used as the framework for analyzing the data derived from the interviews. Dropout had different meanings for different participants. It was understood as a break from treatment, as an end to treatment, or as a means of reduced treatment intensity. Against that background, four main themes for dropout were found: drug craving, negative emotions, personal contact, and activity. Patient and treatment factors seem to interact when participants explore reasons for their dropout. A complex pattern of variables is involved. As remedies, participants suggested that substance use disorder treatment should provide more focus on drug craving and training to understand and tolerate emotional discomfort. They also wanted closer contact with the staff during treatment, more activities, and rigorous posttreatment follow-up. These findings from the user perspective have important implications for substance use disorder treatment, clinical and social work practice, management, and research.

The Efficacy of Dog Assisted Therapy in Detained Drug Users: A Pilot Study in an Italian Attenuated Custody Institute

Drug addiction is a major care and safety challenge in prison context. Nowadays, rehabilitation and specific therapeutic programs are suggested to improve health and well-being of inmates during their detention time and to reduce substance abuse relapse after release from prison. Among these programs, several studies reported the benefits for inmates coming from animal assisted interventions. In this pilot controlled study, we investigated the efficacy of a dog assisted therapy program addressed to 22 drug addicted male inmates housed in an attenuated custody institute in Italy. The study lasted six months, the treated group (12 inmates) was involved once a week for one hour in 20 dog assisted therapy sessions, whereas the control group (10 inmates) followed the standard rehabilitation program. One week before the beginning and one week after the end of the sessions, all inmates involved were submitted to symptom checklist-90-revised and Kennedy axis V. Inmates involved in the dog assisted therapy sessions significantly improved their social skills, reducing craving, anxiety and depression symptoms compared to the control group. Despite the limitation due to the small number of inmates enrolled and to the absence of follow up, we found these results encouraging to the use of dog assisted therapy as co-therapy in drug addicted inmates rehabilitation programs, and we claim the need of more extensive study on this subject.

More Than Just a Break from Treatment: How Substance Use Disorder Patients Experience the Stable Environment in Horse-Assisted Therapy

Inclusion of horse-assisted therapy (HAT) in substance use disorder (SUD) treatment is rarely reported. Our previous studies show improved treatment retention and the importance of the patient–horse relationship. This qualitative study used thematic analysis, within a social constructionist framework, to explore how eight patients experienced contextual aspects of HAT’s contribution to their SUD treatment. Participants described HAT as a “break from usual treatment”. However, four interrelated aspects of this experience, namely “change of focus”, “activity”, “identity”, and “motivation,” suggest HAT is more than just a break from usual SUD treatment. The stable environment is portrayed as a context where participants could construct a positive self: one which is useful, responsible, and accepted; more fundamentally, a different self from the “patient/self” receiving treatment for a problem. The implications extend well beyond animal-assisted or other adjunct therapies. Their relevance to broader SUD policy and treatment practices warrants further study.

Contribution of the patient-horse relationship to substance use disorder treatment: Patients' experiences

BACKGROUND

A good therapeutic relationship is a strong predictor of successful treatment in addiction and other psychological illness. Recent studies of horse-assisted therapy (HAT) have drawn attention to the importance of the client's relationship to the horse in psychotherapy. Few have reported on the patient's own perspective and none have reported specifically on the human-horse relationship in substance use disorder (SUD) treatment and its implications for health and well-being.

AIM

This article explores SUD patients' own experience of their relationship with the horse and their perceptions of its contribution to their therapy.

METHODS

As part of a large mixed-method study of HAT in SUD treatment, we used semi-structured interviews of eight patients to gather information about their experiences of HAT. From the data obtained, the relationship with the horse was found to be a significant part of participants' HAT experience. It is therefore the subject of the current phenomenological study, in which thematic analysis was used to investigate how the participants constructed the reality of their relationship with the horse(s) and their perceptions of the consequences of that reality in SUD treatment.

RESULTS

Participants' own descriptions suggest that the horses were facilitators of a positive self-construct and provided important emotional support during treatment. Analysis found relationship with the horse, emotional effect, and mastery to be important and interrelated themes. The findings were interpreted within an attachment theory context.

CONCLUSION

The results appear to be consistent with key addiction treatment theories and with findings in HAT theoretical and empirical studies. They add to our understanding of the impact of HAT on SUD treatment. However, further research is needed into both the construct validity of the patient-horse therapeutic relationship and the possible variance within and between different populations.
