Future Directions for Research on Human–Animal Interaction in an Aging Population

ABSTRACT

This final paper in the thematic issue, “Human–Animal Interaction and Healthy Human Aging,” highlights and distills key points from the series of papers and provides recommendations for improving and expanding Human–Animal Interaction (HAI) research into healthy human aging. This paper also focuses on translating research to practice and discussing important practical issues related to pet ownership or interaction with companion animals among older adults, and makes specific recommendations for researchers, caregivers, and professionals working with older adults. In addition to issues related to the human side of the equation, we make recommendations for protecting and insuring the health and wellbeing of the animals involved.     

Behavioral effects of the presence of a dog in a classroom

Abstract

To test the idea that dogs have a positive influence on the social behavior of school children, one of three dogs was introduced alternately into a class at an elementary school in Vienna, attended by 24 children (mean age: 6.7 years). Most of the 14 boys and ten girls came from first-generation immigrant families. With parental consent, their behavior was videotaped for two hours every week, during “open teaching situations,” first during a one-month control period in the absence of dogs, followed by an experimental period of similar duration, when a dog was present in the classroom. Frequency and duration of all observable behaviors of individuals and their interactions were coded from these tapes. Although major individual differences were found in the children's interest in the dog and their behavioral responses, the group became socially more homogenous due to decreased behavioral extremes, such as aggressiveness and hyperactivity; also, formerly withdrawn individuals became socially more integrated. Effects were more pronounced in the boys than the girls. Even though the children spent considerable time watching and making contacting with the dog, they also paid more attention to the teacher. We conclude that the presence of a dog in a classroom could positively stimulate social cohesion in children and provide a relatively cheap and easy means of improving teaching conditions.     

Loneliness,Depression, and Physical Activity in Older Adults: The Therapeutic Role of Human–Animal Interactions

ABSTRACT

The global population of older persons is projected in 2050 to reach approximately 2.1 billion. As people age, feelings of loneliness, depression, and physical inactivity often occur due to a multitude of reasons. These feelings may manifest and cause adverse health outcomes. With the predicted increase of older adults worldwide, the prevalence of loneliness, depression, and physical inactivity may also worsen over time if unattended. Since older adults are subject to psychological and physical changes as they age, it is important to find creative ways to address the health needs of this growing population. Therefore, interventions are needed to prevent or decrease the psychological and physical challenges that older adults face. This paper examines existing literature on human–animal interactions (HAIs) in the lives of older adults in relation to concepts such as loneliness, depression, and physical activity. The psychological and physical health benefits of animals for older adults include decreased loneliness and depression, improved cardiovascular health, and increased physical activity. There is mounting evidence supporting the therapeutic psychological and physical health benefits of animals in the lives of older adults. However, there are practical and financial implications that must be considered. Methodological considerations and future directions for human–animal interaction research with older adults are also discussed.     

Does Anthropomorphism of Dogs Affect Pain Perception in Animal-Assisted Interventions? An Exploratory Study

The purpose of this exploratory study was to determine the effects of anthropomorphism of a therapy dog on pain perception during an animal-assisted intervention. Participants were 32 college women who were randomly assigned to the anthropomorphism condition or the control condition. All participants engaged in a pretest cold pressor task to measure base-line individual differences in pain tolerance and perceptions of pain intensity and pain unpleasantness. After completing this task, participants in the anthropomorphism group engaged in a task intended to prime them to view a therapy dog anthropomorphically. Specifically, they rated photos of dogs on a series of humanlike traits (e.g., “this dog would be a good listener”). Participants in the control condition rated photos of dogs on a series of canine traits (e.g., “this dog would make a good watchdog”). After this experimental manipulation, participants engaged in a second cold pressor task in the presence of a therapy dog and the therapy dog handler. We hypothesized that participants in the anthropomorphism group would demonstrate greater pain tolerance and report lower levels of pain intensity and pain unpleasantness during the second cold pressor task than participants in the control group. Results provide partial support for these hypotheses. Participants in the anthropomorphism group reported lower posttest pain intensity than participants in the control group. In addition, they demonstrated greater posttest pain tolerance than participants in the control group—but only under conditions of medium or high pretest pain tolerance. The two groups did not differ with respect to posttest pain unpleasantness. The results of this exploratory study provide preliminary evidence that prompting individuals to view a therapy dog anthropomorphically may augment their experience of pain relief from a therapy dog visit.     

The Human–Animal Interaction Scale: Development and Evaluation

The purpose of this study was to develop the Human–Animal Interaction Scale (HAIS) and evaluate its reliability and validity. The HAIS is a 24-item self-report instrument designed to describe and quantify behaviors performed by humans and nonhuman animals during an episode of interaction (e.g., engaging with a pet, participating in an animal-assisted intervention). Participants were 295 adult volunteers who completed the HAIS in one of several different contexts, including both laboratory and applied settings. The scale was tested across several different species, including companion animals (i.e., dogs and cats), small caged animals (i.e., rats, rabbit, hedgehog), and horses. Analyses indicate good reliability, with a Cronbach’s alpha of 0.82 overall and alphas of 0.72 and higher across the different species and settings. Test-retest analyses indicate ratings remain consistent up to one week following an interaction. Evidence of construct validity was gathered by comparing HAIS ratings with other well-established measures of related constructs, as well as comparing participant reports with researcher observations. Potential uses in basic and applied research are discussed.     

Companion-Animals’ Effectiveness in Managing Chronic Pain in Adult Community Members

ABSTRACT

Therapy animals have been found to alleviate pain in healthcare settings, but companion-animal owners report greater discomfort and use more analgesics than people who do not own one or more companion animals. To investigate this anomaly, 173 adults completed an online survey that included questions about themselves and any companion animal they owned, the Depression Anxiety and Stress Scales, the Numeric Pain Rating Scale, and a modified version of the Chronic Pain Coping Inventory-42. Participants were also invited to contact the researchers to expand on their responses in a semi-structured interview, to which seven owners responded. There was no significant difference between reported pain levels in owners versus non-owners. However, companion-animal owners who reported actively using human–animal interactions to manage their pain rated this as moderately helpful and reported lower pain levels than other owners. There were also no significant differences between owners’ and non-owners’ anxiety or stress levels. Companion-animal owners reported more depressive symptoms than non-owners, but owners with animals perceived as more friendly reported fewer depressive symptoms. Dog owners comprised most of the sample and, for these participants, there was a negative association between perceived dog friendliness and levels of depression and anxiety. Those with more disobedient dogs also experienced greater stress. Interviewees reported that their companion animals helped them cope with pain in many ways, including provision of social and emotional support and by providing a sense of purpose in life. These findings indicate that some, but not all, companion animals may be beneficial for participants with chronic pain. Since the benefits appear to be associated with the species and personality of the animal, and with whether the person actively uses human–animal interactions as a pain-coping mechanism, care should be taken before recommending companion-animal ownership to persons suffering from chronic pain.     

A Longitudinal Study of Decision Making in the Process of Acquiring a Dog

To prevent potential problems in the relationship between people and their dogs, it is important to engage in a thoughtful decision-making process with regard to acquiring a dog. To map the most important elements in the decision-making process, a social cognitive model was applied using seven psychological constructs: perceived advantages of having a dog; perceived disadvantages; the social norm; self-efficacy; optimism; expected commitment; and the intention to acquire a dog. People who were planning to acquire a dog within one year were asked to fill in an online questionnaire and another one 14 months later. The social cognitive constructs were operationalized in the baseline questionnaire, and in the follow-up participants were asked to report whether they had actually acquired a dog during the 14-month interval. The sample (n?=?588) largely consisted of females (88%) and those who had a high level of education (64%). The mean age of the participants was 40.9 years. The data showed significant relations among the decision-making variables, and significant differences between demographic variables related to these. In univariate longitudinal analyses, several social cognitive variables significantly predicted acquiring a dog in the 14-month period. When intention to acquire a dog was entered into the multivariate model, it remained the only predictor (OR = 2.16, p?<?0.001); the model explained 33% of the variance in acquiring a dog. It was possible to assess the main constructs that play a role in decision making regarding acquiring a dog: Most baseline measures were related to actual later behavior, also when taking into account all changes in other internal and external factors that may have taken place. Insight into the decision-making process makes it possible to intervene in it for the good of people, dogs, and their relationships.     

Exploring Social (Non-working) Behavior in Guide Dogs from the Perspective of Guide Dog Owners

The guide dog partnership begins at the point of matching, when careful assessment of a trained guide dog and an understanding of the functional needs and expectations of the prospective owner are considered alongside each other. Guide Dogs UK invest much time and resources to the process of matching a client with a dog in order to fulfil client expectations and create a lasting partnership. This study explores: (1) the meaning and importance of social (non-working) behavior to guide dog owners; (2) how firsthand experience and knowledge shape individual owner expectations for behavior; and (3) how, and in what ways, social behavior impacts the guide dog partnership. The focus group method was used to collect qualitative data from a total of 11 participants. The data were analyzed using a thematic analysis procedure which identified six overarching themes: “social behavior to me means,” internal and external factors influencing social behavior, training and matching, socially desirable and undesirable behaviors, maintaining and managing social behavior, and practical and emotional issues. Findings show that social behavior is as important as guiding skills and mobility for guide dog owners, and behavioral compatibility is held to be crucial in a successful partnership. Participants put an emphasis on consistency of behavior in social settings, while recognizing that a guide dog's non-working behavior is subject to multifarious internal and external influences. The findings of this study indicate an opportunity for Guide Dogs UK, and similar assistance dog organizations, to observe fully the importance of social behavior and, in response, place even greater emphasis on lifestyle and behavioral compatibility when training dogs and matching them with clients.     

Behavior of dolphins towards adults and children during swim-with-dolphin programs and towards children with disabilities during therapy sessions

Abstract

In recent years, dolphin-assisted therapy has become very popular and an increasing number of facilities worldwide offer therapy programs with dolphins. In contrast to other animal-assisted therapy programs, dolphins are not domestic animals; they are mostly caught in the wild and there are still no studies on their behavior during these therapies. However, there is speculation that the behavior of dolphins toward people with mental and physical disabilities may play an important role in the success of the therapy. We observed 83 sessions with five untrained dolphins (Tursiops truncatus) at Dolphins Plus, a fenced area with ocean water in the Florida Keys, USA. Our detailed observations of contact and distance behavior between dolphins and different groups of swimmers (adults, children, and children with mental and physical disabilities) show that, in general, dolphins prefer small humans to adults. One dolphin showed a clear preference toward children with mental and physical disabilities, and we conclude that she showed assisting behavior.     

Dogs in Schools: The Impact of Specific Human–Dog Interactions on Reading Ability in Children Aged 6 to 8 Years

Dog-assisted educational programs, including reading programs, are becoming an area of research focus, based on claims of various advantages for children. However, while available findings typically indicate benefits for the children involved, the low quality of evidence makes it difficult to draw valid inferences. In the current study three dog-assisted programs with clearly defined parameters were developed and evaluated. Sixty-three children, aged 6 to 8 years, were matched on age and gender and pseudo-randomly allocated to one of the three conditions. In one condition the children participated in eight 15–20 minute sessions over a four-week period, in which they worked in pairs to train a dog to complete obstacle course tasks. In a second condition the children spent the same amount of time reading out loud, in pairs, to a stationary dog. In the third condition children participated in normal classroom activities with a dog present in the classroom. This intervention ran for up to four hours per week over the four-week period. Validated measures were used to assess reading abilities pre- and post-intervention. From the results it appeared that children showed significant improvements across time for reading ability for all three conditions, including the condition with minimal dog contact, with no significant group or interaction effects. Exploratory analyses unexpectedly indicated that children who had lower starting abilities displayed the greatest levels of reading improvement. While it cannot be determined that these findings are the result of the presence of the dog alone, they nonetheless may indicate that dog-assisted reading programs are an effective means of benefitting those children who most need help to become fluent readers.     

Impact of different groups of swimmers on dolphins in swim-with-the-dolphin programs in two settings

Abstract

In recent years, dolphin-assisted therapy has become very popular, and an increasing number of facilities worldwide are offering therapy programs that incorporate dolphins. We observed 83 sessions with five dolphins at “Dolphins Plus,” USA, and 37 sessions with 13 dolphins at “Dolphin Reef.” Israel, during unstructured swim-with-the-dolphin programs. Both facilities are fenced sea pens with ocean water. Our detailed observations focused on contact and distance behaviors between dolphins and amongst dolphins with different groups of human swimmers: adults, children and children with mental and physical disabilities at “Dolphins Plus,” and adults only at “Dolphin Reef.” The dolphins at “Dolphins Plus” showed some signs of stress such as avoidance, speed increase, higher metabolism and intensification of a subgroup. These signs were most evident when the dolphins were with adult swimmers. In contrast, the dolphins at “Dolphin Reef” seemed to be attracted to adult swimmers. We will discuss these opposing findings with reference to the different housing conditions. Our results indicate that limited space results in a reduction of the dolphins' attraction for swimmers.     

“They Burn Brightly,But Only for a Short Time”: The Role of Social Workers in Companion Animal Grief and Loss

The human–animal bond is a relational theory which describes the dynamic between humans and nonhuman animals that satisfies needs in each for companionship and emotional support, framing companion animals as valued family members. Social workers have historically ignored the central role companion animals play in the lives of their clients, adopting an anthropocentric view underpinned by human rights and social justice. However, the need for companion animal-inclusive practice features in recent social work literature. As companion animals are intricately woven into the lives of their guardians, it follows that their inevitable death brings a profound sense of loss and thus an opportunity for social work intervention. The aim of this research was to see if there was a role for social work practitioners to support grieving animal companion guardians. Qualitative thematic analysis was performed on 218 candid online responses to an article on the topic of losing a companion animal, from which four major themes were identified: strength of the bond, anthropocentrically disenfranchised grief, anticipatory grief in the context of euthanasia, and the need for professional support. This analysis demonstrates the strength of the human– animal bond, illustrates how the dominant anthropocentric hegemony disenfranchises this variety of grief and loss, describes the experience of anticipatory grief in the context of euthanasia, and identifies the need for professional support. Implications for social work practice are identified, with opportunities for social workers to exchange their anthropocentric approach for a biocentric view, provide support to veterinarians and other professionals, and to work toward challenging the social constructs, which disenfranchise companion animal loss.
