Routine surveying of academic centers focused on the human-animal bond is critical to understand the trajectory of the field and to create an environment where centers can learn from one another and build collaborations. The purpose of this manuscript was to report the findings of a survey of these human-animal bond centers, to summarize the status of the field, and to identify changes within the field since 2016. Survey questions concentrated on the demographic characteristics, engagement programs, educational opportunities, and research focuses of the centers. Findings suggest that the field continues to grow as one-third of human-animal bond centers are less than 10 years old. The number of centers that participated in this survey increased by 31% compared with the previous survey. Centers have developed a variety of engagement programs, including animal-assisted intervention and companion animal education programs. About half of the centers (48%) offer degree programs and about one quarter of the centers (24%) offer certificate programs. Most centers (95%) focus their research on companion animals with the most studied companion animal being dogs (95%). The most frequent data collection method was surveys (86%). Qualitative analyses, behavior measures, and physiological measures were also common. The most notable changes from the 2016 survey include overall growth of the field (indicated by the establishment of new centers) and a shift in the specialty area of directors, moving from 44% of directors being veterinarians in 2016 survey to 90% having a human-focused specialty in the 2021 survey. Most centers’ research focused on animal-assisted interventions that are consistent with the previous survey. As the field of the human-animal bond continues to grow and more centers emerge, ongoing evaluation of offerings is important to track changes, identify needs, and foster success.

Military deployment and reintegration challenges permeate the lives and relationships of Veterans, their spouses, and their families. Among these challenges, 23% of post-9/11 Veterans have been diagnosed with posttraumatic stress disorder (PTSD). Psychiatric service dogs have been found to help clinically alleviate PTSD symptoms when used as a complementary intervention. However, minimal research exists that explores the role of the service dog as a mechanism for cultivating resilience within the military family system. Researchers utilized a qualitative, constant comparative approach to analyze self-reported experiences of 101 individuals, including Veterans (n = 67) and their spouses (n = 34). Analyzed through the framework of the Theory of Resilience and Relational Load (Afifi et al., 2016 (See CR3)), findings suggest complex communication processes that facilitate relational and family adaptation. These processes encompassed (a) the role of the service dog in building emotional reserves, (b) relational load introduced when caring for the service dog, and (c) the service dog's facilitation of relational maintenance behaviors among family members that contributed to communal orientation. Based on the results of this qualitative analysis, researchers suggest educational interventions where service dog trainers and mental health practitioners can incorporate relational maintenance strategies and family-focused approaches to integrating service dogs as military family members., Author(s): Leanne O.

Recent studies suggest a therapeutic effect of psychiatric service dogs for military veterans with posttraumatic stress disorder (PTSD), but are limited by self-report biases. The current study assessed the effect of PTSD service dogs on the salivary cortisol awakening response (CAR) and arousal-related functioning in a population of military veterans with PTSD. Participants included 73 post-9/11 military veterans with PTSD including 45 with a service dog and 28 on the waitlist to receive one. Saliva samples were collected on two consecutive weekday mornings at awakening and 30 min later to quantify the cortisol awakening response (CAR) and its area under the curve (AUCi) in addition to standardized survey measures of anxiety, anger, sleep quality and disturbance, and alcohol abuse. There was a significant main effect of having a service dog on both the CAR and the AUCi, with individuals with a service dog exhibiting a higher CAR and AUCi compared to those on the waitlist. Results also revealed that those with a service dog reported significantly lower anxiety, anger, and sleep disturbance as well as less alcohol abuse compared to those on the waitlist, with medium to large effect sizes. Although those with a service dog reported significantly less PTSD symptom severity, CAR was not significantly associated with PTSD symptoms within or across group. In conclusion, results indicate that the placement of a PTSD service dog may have a significant positive influence on both physiological and psychosocial indicators of wellbeing in military veterans with PTSD. Although clinical significance cannot be confirmed, a higher CAR/AUCi among those with a service dog may indicate better health and wellbeing in this population. Future within-subject, longitudinal research will be necessary to determine potential clinical significance and impact of individual differences.

Introduction: Sleep disturbances, fear of sleep, and nightmares are among the most reported symptoms for military service members and veterans (henceforth "veterans") with posttraumatic stress disorder (PTSD), potentially contributing to treatment resistance and heightened suicidality. Despite available evidence-based interventions, many veterans still report difficulties. The complementary intervention of a psychiatric service dog may contribute to improvements in sleep quality for veterans with PTSD. Methods: This preregistered, non-randomized clinical trial evaluated the association between service dog partnership and sleep at 3 month follow-up. Participants were N = 155 veterans with PTSD (81 in the service dog group and 74 waitlisted controls). Measures included self-report surveys measuring PTSD severity (PTSD Checklist for DSM-5, PCL-5) sleep quality (Pittsburgh Sleep Quality Index, PSQI), sleep disturbance (PROMIS Sleep Disturbance), and fear of sleep (Fear of Sleep Inventory-Short Form, FoSI-SF); morning sleep diaries measuring nightmares; and wrist-worn actigraphy. Regression models and mediation analyses were performed. Results: Service dog partnership was significantly associated with better subjective sleep [PSQI: mean difference -2.2, 95% CI (-3.4, -1.1), p < 0.001; PROMIS Sleep Disturbance: -3.6, 95% CI (-6.3, -0.9), p = 0.004; FoSI-SF: -6.6, 95% CI (-9.7, -3.5), p < 0.001] and odds of nightmares [OR = 0.45, 95% CI (0.26, 0.76), p = 0.003]. Service dog partnership was not associated with a change in actigraphy-based measures of sleep [sleep onset: -4.5, 95% CI (-12.2, 3.2); sleep duration: -4.7, 95% CI (-25.9, 16.6); wake after sleep onset: 6.0, 95% CI (-2.1,14.1); sleep efficiency: -0.4, 95% CI (-3.4, 2.5)]. The estimated proportion of the effect of service dogs on PTSD severity mediated by fear of sleep was 0.26 [95% CI (0.10, 0.48)]. Discussion: Compared to the control group, veterans with service dogs for PTSD reported better sleep quality, less sleep disturbance, and less fear of sleep after 3 months. However, service dog partnership was not associated with differences in actigraphy-measured sleep. These findings demonstrate the impact of psychiatric service dog partnerships on sleep quality for veterans with PTSD. [ABSTRACT FROM AUTHOR]

The Observation of Human-Animal Interaction for Research (OHAIRE) is a coding tool developed to capture the behavior of children when interacting with social partners and animals in naturalistic settings. The OHAIRE behavioral categories of focus are emotional displays, social communication behaviors toward adults and peers, behaviors directed toward animals or experimental control objects, and interfering behaviors. To date, the OHAIRE has been used by 14 coders to code 2,732 min of video across four studies with a total of 201 participants ages 5 to 18 years (M = 10.1, SD = 2.5). Studies involved animal-assisted intervention with three species (i.e., dogs, horses, and guinea pigs) and three populations (i.e., autism spectrum disorder, attention-deficit hyperactivity disorder, and typically developing children) in a school, a therapeutic horseback riding program, a group therapy program, and the hospital setting. We explored the psychometric properties of the OHAIRE through analyses of its inter-rater reliability, intra-rater reliability, convergent and divergent validity, and internal structure, using data from these four human-animal interaction studies. The average inter-rater reliability was excellent (kappa = 0.81), with good reliability in most of the behavioral categories coded. Intra-rater reliability was consistently excellent (0.87 ≤ kappa ≤0.96). Internal structure analyses with Cronbach's alpha supported the exploratory use of subscales to measure social communication behaviors toward peers (α = 0.638) and adults (α = 0.605), and interactions experimental control objects (α = 0.589), and the use of a subscale to measure interactions with animals (α = 0.773). Correlation analyses with multiple questionnaires showed a convergence between positive emotional display and social behaviors as assessed by the OHAIRE and social skills as assessed by the Social Skills Rating System (SSRS) and the Social Communication Questionnaires (SCQ). Little concordance was found between the OHAIRE and the Social Responsiveness Scale (SRS) or the Aberrant Behavior Checklist-Community (ABC). The OHAIRE shows promise for wider use in the field of Human-Animal Interaction, with a need for generalization across more settings and ages.

There is preliminary research suggesting that animal-assisted activities can improve social interactions of children with autism spectrum disorder. This pilot study sought to investigate the benefits of animal-assisted activities with dogs and psychiatrically hospitalized youth with autism spectrum disorder. Participants were recruited from a specialized inpatient psychiatric hospital unit for youth with autism spectrum disorder and other developmental disabilities. Utilizing a crossover design, participants served as their own control by engaging in two 10-min conditions: an experimental dog and handler interaction (animal-assisted activities) and a novel toy and handler control (control). Of the 142 youth aged 6-8 years screened for participation, 47 completed both conditions. Participants' behavioral data were captured via video and coded using the Observation of Human-Animal Interaction for Research, a tool specifically developed to capture human behavioral interactions in the presence of animals. Overall, social-communication behaviors significantly improved in the animal-assisted activities experimental condition compared to the control condition (p = 0.0001). Specifically, participants in the animal-assisted activities experimental condition displayed more positive emotional facial expressions (p ? 0.0001), talking (p = 0.0408), use of gestures (p = 0.032), and looking at both adults and peers (p ? 0.0001). In addition, a higher frequency of constant motion (p = 0.003) was observed in the animal-assisted activities experimental condition. Results suggest that animal-assisted activities with a dog may promote social-communication behaviors in psychiatrically hospitalized youth with autism spectrum disorder. Given the fact that social and communication behaviors can facilitate treatment engagement for this population, we recommend future studies examine how such improvements can positively affect the psychiatric treatment of this population.

Introduction: Service dogs are an increasingly popular complementary intervention for children with autism spectrum disorder. However, despite increasing demand, there remains a lack of empirical research on their potential benefits. The purpose of this study was to evaluate the effects of service dogs on children with autism and their caregivers. Methods: A total of N = 75 families of children with autism were recruited from a non-profit service dog provider in the US, including n = 39 families previously placed with a service dog and n = 36 families engaging in usual care while on the waitlist. Caregivers completed an online survey containing both self- and proxy-report standardized measures of child, caregiver, and family functioning. Linear regressions modeled the relationship between service dog presence and survey outcomes, controlling for relevant child and caregiver covariates. Results: Results indicated that having a service dog was associated with significantly better child sleep behaviors, including better sleep initiation and duration and less sleep anxiety/co-sleeping with medium effect sizes. However, service dog presence was not significantly related to child withdrawal, negative emotionality, emotional self-control, hyperactivity, irritability, and lethargy with small effect sizes. For caregivers, having a service dog was not significantly related to standardized measures of caregiver strain, sleep disturbance, depression, or the impact of the child's condition on family functioning with small effect sizes. Supplemental matched case-control analyses confirmed these findings. Discussion: In conclusion, service dogs were found to positively impact sleep behaviors among children with autism, but may not uniformly relate to other areas of child and caregiver wellbeing. Prospective longitudinal designs, larger sample sizes able to detect small effects, and studies that measure sleep using objective methods are needed to build on these findings.

Partners of veterans diagnosed with posttraumatic stress disorder (PTSD) are at risk of a variety of challenges, and it is unknown whether psychiatric service dogs are disruptive to their sleep or provide similar benefits that are seen in the limited literature on veterans. As part of a larger clinical trial examining the efficacy of psychiatric service dogs for veterans with PTSD and their families, this study focused on sleep patterns of veterans' partners (n = 88), incorporating both subjective (clinically validated self-report surveys) and objective sleep measures (actigraphy). Linear regression was used to analyze differences in relation to group (intervention versus control) at follow-up, controlling for baseline score. Results revealed no significant differences between groups for both the subjective surveys (p = 0.15; p = 0.75) and the objective actigraphy measures (p = 0.06–0.98). This suggests that psychiatric service dogs are not disruptive, nor do they provide any benefits to partner sleep. Partners had sleep patterns on par with national norms at baseline and remained at such levels at follow up. Ultimately, using both subjective and objective measures, we found no impact of psychiatric service dogs on the sleep of veterans' partners.

Including animals in autism intervention is growing in both research and practice. A systematic literature review was conducted to collate and synthesize all empirical research on animal-assisted intervention (AAI) for autism published from 2012 to 2015. Findings from 28 included studies revealed that AAI programs generally include one animal per participant with a total contact time of approximately 10 hours over the course of 8 to 12 weeks. Research methodology is diverse and though limited in many cases, has improved over the last few years. The most commonly reported outcome was increased social interaction, which was unanimously significant across 22 studies. The need for further research is highlighted, calling for a focus on refining AAI techniques, identifying optimal circumstances for positive change as well as individuals who may not benefit, and independent replication of high quality studies to move AAI from an enrichment activity to an evidence-based practice for autism.

Mobility and medical alert service dogs are an assistive technology for individuals with disabilities or chronic conditions. Informal caregivers of individuals with disabilities are subject to physical and emotional stress due to their responsibilities. Understanding how service dogs, an increasingly common assistive technology, may add to or subtract from caregiver stress is crucial for promoting caregiver well-being. The purpose of this study was to analyze caregiver accounts to understand their perspective on benefits and challenges they face with mobility and medical alert service dogs. Open ended survey responses from 117 caregivers of service dog recipients (N = 72 with a service dog, N = 45 on the waitlist) were analysed through a conventional content analysis. Four major themes were found regarding caregiver and service dog: Family Benefits, Caregiver Benefits, Assistance Through Service Dog's Training, and Drawbacks. Findings suggest that benefits and challenges of mobility and medical service dogs extend beyond the service dog recipient, affecting the caregiver and other family members as well. Future studies should further explore this interaction to determine the best way to support caregivers of individuals with disabilities. Mobility and medical alert service dogs are increasingly partnered with individuals with disabilities or chronic diseases as an assistive technology but few studies have focussed on the experience of the caregivers of service dog recipients. Caregivers of individuals with disabilities or chronic diseases may be subject to both psychological and physiological stressors as a result of their caregiver duties. Results found that caregivers perceive both benefits to themselves and to their families in terms building a bond with the animal that helps to reduce worry and offers emotional support. The most commonly mentioned drawbacks include general maintenance of the service dog, grooming needs and travel restrictions. This research is important in order to offer appropriate support to caregivers of individuals with disabilities. [ABSTRACT FROM AUTHOR]

The inclusion of animals in therapeutic activities, known as animal-assisted intervention (AAI), has been suggested as a treatment practice for autism spectrum disorder (ASD). This paper presents a systematic review of the empirical research on AAI for ASD. Fourteen studies published in peer-reviewed journals qualified for inclusion. The presentation of AAI was highly variable across the studies. Reported outcomes included improvements for multiple areas of functioning known to be impaired in ASD, namely increased social interaction and communication as well as decreased problem behaviors, autistic severity, and stress. Yet despite unanimously positive outcomes, most studies were limited by many methodological weaknesses. This review demonstrates that there is preliminary "proof of concept" of AAI for ASD and highlights the need for further, more rigorous research.

Introduction: Service dog placements for autistic children are growing in popularity, yet findings to date are mixed. Moreover, no study to date has examined these placements through the lens of a recognized theoretical model. The purpose of this study is twofold: to explore experiences reported by caretakers of autistic children involved in a service dog program, and to contextualize findings within an established theoretical framework. Methods: A total of n = 50 caretakers of autistic children (n = 38 with and n = 12 without a service dog) were recruited through the national non-profit service dog provider Canine Companions. Participants completed an online survey through Qualtrics which asked open-ended questions about their experiences, both negative and positive. Results: Constant comparative analysis identified two high level themes, nested within a family systems approach framework: (1) Enhancing social functioning of the family system unit and (2) Fostering stability and strength within family system subunits. These themes interacted holistically to foster and reinforce family system resilience. Placements led to greater social inclusion for children and their families, acted as a highly individualized intervention, and decreased experiences of judgement and stigma. Perceived as members of the family, service dogs may coregulate with the autistic child and family members and can be a source of joyful connection within the family. Discussion: Results highlighted the service dog's influence on the entire family (beyond the autistic child). Implications for service dog organizations suggest it may be helpful to account for family-wide impacts throughout the placement process. High standards on the part of provider organizations may minimize negatives, optimizing outcomes for both humans and canines. Ultimately, findings enrich our understanding of service dog interventions for autistic children. [ABSTRACT FROM AUTHOR]
