Exploring the Relationship between Persons with Hearing Loss/Deafness and Their Hearing Dogs.

The reported positive outcomes of animal-assisted services have led to an emerging interest in many different aspects of human-animal interactions. The influence of an assistance animal is thought to encompass several psychosocial domains in the life of a person with a significant health impairment. However, little is known about the mechanisms underlying the relationship between Hearing Dogs and their owners. A prospective study design using a written questionnaire method was utilized to survey 58 current and 23 prospective Australian Lions Hearing Dogs owners. The Pet Expectations Inventory (PEI) was used to investigate the anticipated role of Hearing Dogs in waitlisted persons with hearing loss/Deafness, whereas the Lexington Attachment to Pets Scale (LAPS) was completed by current owners to assess emotional attachment. The results revealed a high mean PEI score (M = 73.1, SD = 10.9, Mdn = 73.0, range: 55-91), with prospective owners strongly expecting the role of Hearing Dogs to include companionship/love and security. Furthermore, strong attachment features were evident in the owners' relationships with Hearing Dogs, as demonstrated by a high total LAPS score (M = 81.2, SD = 7.5, range: 63-91). Mean scores for statements within the "people substitution" category were highest (range = 3.6/4.00-3.9/4.00). In this demographically homogenous study cohort, it appeared that the high expectations of potential Hearing Dog owners for their animals to serve supportive roles beyond hearing assistance should be achievable, as evidenced by the strong attachment relationships displayed between Hearing Dogs and their owners.

The Role and Relevance of Hearing Dogs from the Owner’s Perspective: An Explorative Study among Adults with Hearing Loss

This study aimed to explore perceptions and experiences about how owning a hearing dog can influence the functioning and the autonomy of people with hearing loss. Three adults participated in a semi-structured interview. The interviews were video recorded, transcribed, and coded. A procedure combining qualitative content analysis and interpretative phenomenological analysis was used. The study shows how specific aspects of hearing dogs are associated with increased autonomy and sense of security among owners. The attentive dog-owner pairing, the outstanding training and the companion role of the hearing dog are the main elements supporting the high satisfaction related by all the participants. In regard of the location context (Quebec, Canada), ongoing challenges for owners are reflected in the lack of visibility of this rehabilitation means and its poor recognition from the society, resulting in the constant burden to explain the dog's work to others. For adults with hearing loss, the hearing dog is a relevant way of offering both the benefits of functional assistance and the psychosocial support of a pet. The association between owning a hearing dog and improved overall well-being suggests that this form of rehabilitation should be considered as a pertinent option by hearing health professionals.

Hearing dogs for people with severe and profound hearing loss: a wait-list design randomised controlled trial investigating their effectiveness and cost-effectiveness

BackgroundHearing loss increases the risk of poor outcomes across a range of life domains. Where hearing loss is severe or profound, audiological interventions and rehabilitation have limited impact. Hearing dogs offer an alternative, or additional, intervention. They live permanently with recipients, providing sound support and companionship.MethodsA single-centre, randomised controlled trial (RCT) evaluated the impacts of a hearing dog on mental well-being, anxiety, depression, problems associated with hearing loss (responding to sounds, fearfulness/social isolation), and perceived dependency on others. Participants were applicants to the UK charity ‘Hearing Dogs for Deaf People’. Eligibility criteria were as follows: first-time applicant; applying for a hearing dog (as opposed to other support provided by the charity). Participants were randomised 1:1 to the following: receive a hearing dog sooner than usual [HD], or within the usual application timeframe (wait-list [WL] comparator). The primary outcome was mental well-being (Short Warwick-Edinburgh Mental Well-Being Scale) 6 months (T1) after HD received a hearing dog. The cost-effectiveness analysis took a health and social care perspective.ResultsIn total, 165 participants were randomised (HD n = 83, WL n = 82). A total of 112 (67.9%) were included in the primary analysis (HD n = 55, WL n = 57). At T1, mental well-being was significantly higher in the HD arm (adjusted mean difference 2.53, 95% CI 1.27 to 3.79, p < 0.001). Significant improvements in anxiety, depression, functioning, fearfulness/social isolation, and perceived dependency, favouring the HD arm, were also observed. On average, HD participants had used fewer statutory health and social care resources. In a scenario whereby costs of provision were borne by the public sector, hearing dogs do not appear to be value for money. If the public sector made a partial contribution, it is possible that hearing dogs would be cost-effective from a public sector perspective.ConclusionsHearing dogs appear to benefit recipients across a number of life domains, at least in the short term. Within the current funding model (costs entirely borne by the charity), hearing dogs are cost-effective from the public sector perspective. Whilst it would not be cost-effective to fully fund the provision of hearing dogs by the public sector, a partial contribution could be explored.Trial registrationThe trial was retrospectively registered with the International Standard Randomised Controlled Trial Number (ISRCTN) registry on 28.1.2019: ISRCTN36452009.

The impact of owning a hearing dog on quality of life, hearing handicap, and social functioning: an Australian cohort

Objective To determine the impact of owning a hearing dog on self-reported hearing handicap, quality of life (QoL), and social functioning. Design Group comparison study design, utilising five surveys (General Information Survey, Hearing Information Survey, Hearing Handicap Inventory for the Elderly/Adults, Medical Outcomes Survey, and Social Functioning Questionnaire). Study sample 23 respondents from the 2019 Australian Lions Hearing Dog waitlist (controls) and 58 respondents from all clients who had received a hearing dog through the Australian Lions Hearing Dog service (cases). Results No significant difference was found in Hearing Handicap Inventory or Social Functioning Questionnaire scores between the groups, although there was a tendency for improvement with dog ownership. The owner group scored significantly lower than the waitlist group on three Medical Outcomes Survey sub-items (general health, physical functioning, and role limitations due to physical health), along with total health-related QoL. These results contrasted with the broad emotional and psychosocial benefits identified through thematic analysis of responses. Conclusions It is feasible, yet not certain, that owning a hearing dog may bring a reduction in hearing handicap, as well as emotional and social benefits to the QoL of individuals, but it also appears to be associated with poorer perception of health.

The effects of assistance dogs on psychosocial health and wellbeing: A systematic literature review.

Beyond the functional tasks that assistance dogs are trained for, there is growing literature describing their benefits on the psychosocial health and wellbeing of their handlers. However, this research is not only widely disparate but, despite its growth, has not been reviewed since 2012. Our objective was to identify, summarize, and methodologically evaluate studies quantifying the psychosocial effects of assistance dogs for individuals with physical disabilities. Following PRISMA guidelines, a systematic review was conducted across seven electronic databases. Records were independently screened by two authors. Studies were eligible for inclusion if they assessed outcomes from guide, hearing, medical, or mobility service dogs, if they collected original data on handlers' psychosocial functioning, and if the outcome was measured quantitatively with a validated, standardized measure. Studies on psychiatric service dogs, emotional support dogs, and pet dogs were excluded. Of 1,830 records screened, 24 articles were identified (12 publications, 12 theses) containing 27 studies (15 cross-sectional, 12 longitudinal). Studies assessed the effects of mobility (18), hearing (7), guide (4), and medical (2) assistance dog partnerships with an average sample size of N = 83. An analysis of 147 statistical comparisons across the domains of psychological health, quality of life, social health, and vitality found that 68% of comparisons were null, 30% were positive in the hypothesized direction, and 2% were negative. Positive outcomes included significant effects of having an assistance dog on psychological wellbeing, emotional functioning, self-esteem, and vitality. However, it is of note that several methodological weaknesses of the studies make it difficult to draw any definitive conclusions, including inadequate reporting and a failure to account for moderating or confounding variables. Future research will benefit from stronger methodological rigor and reporting to account for heterogeneity in both humans and assistance dogs as well as continued high-quality replication.

To live with a wagging tailed assistant – Service and hearing dog ownership from the perspective of Swedish owners

Individuals who have a functional or health impairment, are often in great need of conventional healthcare, social care and support, as well as help from family and friends. The use of dogs may be an important assistive support for this population. Assistance dogs are trained to assist with their owners’ specific needs. The aim of this study is to explore service and hearing dog ownership from the owner´s perspective, by examining the owner's expectations before training a dog, and experiences after having a certified dog. This study was designed as a longitudinal intervention study with pre‐post design. The participants included in the study trained their own dogs to become service or hearing dogs. A number of open‐ended questions were answered by the participants before the training of the dog started, three months after the dog was certified, and 1–3 years after the first follow‐up. Data were analysed using thematic content analysis. The participants’ expectations of what the dog would contribute after being certified was high. Their perceived experiences in many ways reflected their expectations. For example, they perceived that the dog contributed to improved health status, a more active lifestyle, improved ability to feel secure, and that they had become more independent. They also felt that the dog had strengthened their social relationships. Negative experiences were also identified. Not being allowed to bring their dog into public places and negative attitudes from other people were examples of this. This study shows that individuals being supported by an assistance dog experience the dog as an invaluable help in their everyday life. By improving the owners’ lives in many ways, a certified service or hearing dog is a novel and important assistive support for people with a functional or health impairment.

BackgroundHearing assistance dogs not only alert their hearing-impaired owners to environmental sounds but may also improve their quality of life. Unfortunately, audiologists rarely recommend this service, potentially due to a dearth of associated literature. This study explores the demographic and audiological characteristics, general health, socio-emotional functioning, and expectations of persons seeking a hearing dog.Material and methodsThis prospective cohort study of 23 respondents from the 2019 Australian Lions hearing dog waitlist utilized a written survey method.ResultsRespondents were predominately female (78%), financially stable (91%), had previous pet ownership experience (91%), a self-reported severe/profound sensorineural hearing loss (92%), and were regular hearing device users (87%). Respondents reported substantial social and emotional limitations. Overall, the health function of respondents was below that of the general population. Social function was also comparatively impaired. Most respondents strongly agreed that the hearing dog should be “a companion” and “a living thing to love.”ConclusionsRespondents were demographically varied but were regular hearing-device users, with significant social, emotional, and health limitations. In addition to being alerted to environmental sounds, respondents expected the hearing dog to serve a broad socio-emotional function.

Effectiveness and Cost-Effectiveness of Receiving a Hearing Dog on Mental Well-Being and Health in People With Hearing Loss: Protocol for a Randomized Controlled Trial.

BackgroundPeople with hearing loss, particularly those who lose their hearing in adulthood, are at an increased risk of social isolation, mental health difficulties, unemployment, loss of independence, risk of accidents, and impaired quality of life. In the United Kingdom, a single third-sector organization provides hearing dogs, a specific type of assistance dog trained to provide sound support to people with hearing loss. These dogs may also deliver numerous psychosocial benefits to recipients. This has not previously been fully investigated.ObjectiveThe study aims to evaluate the impact of a hearing dog partnership on the lives of individuals with severe or profound hearing loss.MethodsA 2-arm, randomized controlled trial will be conducted within the United Kingdom with 162 hearing dog applicants, aged 18 years and older. Participants will be randomized 1:1 using a matched-pairs design to receive a hearing dog sooner than usual (intervention arm: arm B) or to receive a hearing dog within the usual timeframe (comparator arm: arm A). In the effectiveness analysis, the primary outcome is a comparison of mental well-being 6 months after participants in arm B have received a hearing dog (arm A have not yet received a hearing dog), measured using the Short Warwick Edinburgh Mental Well-Being Scale. Secondary outcome measures include the Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, and Work and Social Adjustments Scale. An economic evaluation will assess the cost-effectiveness, including health-related quality-adjusted life years using the EuroQol 5 Dimensions and social care–related quality-adjusted life years. Participants will be followed up for up to 2 years. A nested qualitative study will investigate the impacts of having a hearing dog and how these impacts occur.ResultsThe study is funded by the National Institute for Health Research’s School for Social Care Research. Recruitment commenced in March 2017 and is now complete. A total of 165 participants were randomized. Data collection will continue until January 2020. Results will be published in peer-reviewed journals and at conferences. A summary of the findings will be made available to participants. Ethical approval was received from the University of York’s Department of Social Policy and Social Work Research Ethics Committee (reference SPSW/S/17/1).ConclusionsThe findings from this study will provide, for the first time, strong and reliable evidence on the impact of having a hearing dog on people’s lives in terms of their quality of life, well-being, and mental health.Trial RegistrationInternational Standard Randomised Controlled Trial Number Registry ISRCTN36452009; http://www.isrctn.com/ISRCTN36452009International Registered Report Identifier (IRRID)DERR1-10.2196/15452

The Impact of Owning a Guide Dog on Owners’ Quality of Life: A Longitudinal Study

ABSTRACTIndividuals with visual impairments often report low quality of life (QOL), increased depression, and reduced functionality. Trained assistance dogs have been shown to help improve QOL and daily functioning of individuals affected by chronic conditions, but these studies have been largely crosssectional and QOL has not been considered in guide dog owners. A longitudinal cohort study was undertaken using the Flanagan Quality of Life Scale to compare individuals on the UK guide dog national waiting list and established guide dog owners at two time points. Data collected from both time points were compared between three groups: those who remained on the waiting list throughout the study (n = 17), those who acquired a guide dog during the study (n = 15), and established guide dog owners (n = 14). Analysis comparing the effect of “group” was conducted on individual questionnaire items as well as total quality of life scores. Individuals who acquired a guide dog during the study showed a significant increase in perceptions of independence in comparison with those who remained on the waiting list. In general, those in the established guide dog group and those who acquired a guide dog demonstrated increased perceived QOL over time, but those who remained on the waiting list showed a decrease. Owing to the small sample sizes we computed effect sizes to inform the development of future studies. Effect sizes were highest on items relating to health, material comforts, independence, and total QOL. Comparison with previous research looking at QOL with hearing dog and physical assistance dog partners showed that guide dog ownership may be specifically associated with perceived gains in terms of material comforts and inter-personal relationships.

Certified service dogs – A cost-effectiveness analysis appraisal

IntroductionIndividuals with functional impairments or chronic diseases are often in need of assistance in their daily lives. For these individuals it is essential to find novel, cost-effective solutions to meet their needs. Service dogs are dogs that are specially trained to assist individuals with functional impairments and may be able to improve these individuals’ quality of life at a reasonable cost, i.e. be cost effective. Cost-effectiveness analyses are used to illustrate the cost of an intervention in relation to its effects and provide important input to decision-makers when setting priorities.AimThe aim of this study is to assess the cost effectiveness of a certified physical service dog and a diabetes alert dog compared to a regular companion dog.MethodCosts, life years and quality-adjusted life years were estimated over a 10-year time horizon using a decision-analytic model built upon evidence from the”service and hearing dog project”. The primary outcome was the incremental cost-effectiveness ratio expressed as cost per gained quality-adjusted life year. The analysis was conducted from a societal perspective. Costs and effects were discounted with 3% per annum and reported in USD.ResultsCompared to a regular companion dog, a physical service dog is cost saving [-6,000 USD] and gives the dog owner more quality-adjusted life years [0.28]. The diabetes alert dog is also cost effective in comparison with a regular companion dog [-4,500 USD, 0.06 QALYs].ConclusionThis study indicates that a certified service dog is cost saving in comparison with a regular companion dog for individuals with functional impairments or chronic diseases. The uncertainty of the analysis implies that further studies are needed in order to confirm these results. Nevertheless, physical service dogs and diabetes alert dogs show potential to be a valuable support and decision analytic models are useful tools to provide this information.

The impact of service and hearing dogs on health-related quality of life and activity level: a Swedish longitudinal intervention study

BackgroundIndividuals with severe disability often require personal assistance and help from informal caregivers, in addition to conventional health care. The utilization of assistance dogs may decrease the need for health and social care and increase the independence of these individuals. Service and hearing dogs are trained to assist specific individuals and can be specialized to meet individual needs. The aim of this study was to describe and explore potential consequences for health-related quality of life, well-being and activity level, of having a certified service or hearing dog.MethodsA longitudinal interventional study with a pre-post design was conducted. At inclusion, all participants in the study had a regular (untrained) companion dog. Data were collected before training of the dog started and three months after certification of the dog. Health-related quality of life was assessed with EQ-5D-3L, EQ-VAS and RAND-36. Well-being was measured with WHO-5 and self-esteem with the Rosenberg Self-Esteem Scale. In addition, questions were asked about physical activity and time spent away from home and on social activities. Subgroups were analyzed for physical service and diabetes alert dogs.ResultsFifty-five owner-and-dog pairs completed the study (30 physical service dogs, 20 diabetes alert dogs, 2 epilepsy alert dogs, and 3 hearing dogs). Initially, study participants reported low health-related quality of life compared with the general population. At follow-up, health-related quality of life measured with the EQ-VAS, well-being and level of physical activity had improved significantly. In the subgroup analysis, physical service dog owners had lower health-related quality of life than diabetes alert dog owners. The improvement from baseline to follow-up measured with EQ-5D statistically differed between the subgroups.ConclusionsThe target population for service and hearing dogs has an overall low health-related quality of life. Our study indicates that having a certified service or hearing dog may have positive impact on health-related quality of life, well-being and activity level. Service and hearing dogs are a potentially important “wagging tail aid” for this vulnerable population, able to alleviate strain, increase independence, and decrease the risk of social isolation.Trial RegistrationThe trial was retrospectively registered in http://clinicaltrial.gov, NCT03270592.

Effects of assistance dogs on persons with mobility or hearing impairments: A pilot study

Service dogs help persons with mobility impairments by retrieving items and performing other tasks. Hearing dogs alert persons with hearing impairments to environmental sounds. We conducted a pre-post, wait list-controlled pilot study to assess the impact of the dogs on the lives of recipients. Participants were recruited through two assistance dog training organizations and completed an initial questionnaire packet. The Experimental group completed another packet 6 months after receiving a dog. The Control group completed a second packet 6 months after the initial data collection. On average, dog recipients were very satisfied with their assistance dogs. Both service and hearing dog recipients reduced their dependence on other persons. Service dog recipients reduced hours of paid assistance. No other significant change occurred in various standardized outcome measures. Assistance dogs had a major positive impact on the lives of recipients. More appropriate measurement instruments are needed to capture the impact of these dogs.

Hearing Dogs: A Longitudinal Study of Social and Psychological Effects on Deaf and Hard-of-Hearing Recipients

The organization Hearing Dogs for Deaf People provides assistance dogs that alert their deaf or hard-of-hearing recipients to key sounds, thus increasing their independence and also providing companionship. Fifty-one recipients took part in a longitudinal study to monitor the dogs' working performance over time and to examine the social and psychological effects of having a Hearing Dog. The Profile of Mood State (POMS) questionnaire and the General Health Questionnaire (GHQ) were used together with a Hearing Dog Questionnaire (HDQ) specifically developed for this study. There were a number of significant differences in measures of well-being between the period prior to placing the Hearing Dog and the period after placement, but there were no comparable differences during the year-long waiting period prior to placement of the dog. Recipients reported significant reductions in hearing-related problems such as response to environmental sounds; significant reductions in measures of tension, anxiety, and depression; and significant improvements in social involvement and independence. The longitudinal nature of this study supports evidence that these improvements persist for some time after the placement of a dog, with significant differences being reported, in many cases, up to 18 months after acquiring a dog.

The socializing role of hearing dogs

The relationships between hearing dog ownership and the owners' levels of loneliness, changes in social interactions with people, and life stress were studied retrospectively by questionnaire in a sample of 38 hearing dog owners and a control group of 15 prospective owners. The hearing dogs fulfilled the owners' primary expectation of alerting them to sounds. A sense of security, their second highest concern, was also addressed. Owners felt safer when they were alone with their hearing dog than before obtaining one. Companionship was the third-rated reason for acquiring the dog and owners reported being significantly less lonely after receiving a hearing dog (P < 0.01). Most owners and prospective owners described a role of the hearing dog as changing interactions within the family. Owners also felt that the dogs changed their interactions with the hearing community and neighbors, whereas few prospective owners foresaw this effect of the dog (P < 0.01). Apparently stemming from the disability being more obvious, owners also scored lower on a life stress score than prospective owners (P < 0.02).
