Areas of Emphasis
My research takes a biobehavioral approach towards the study of human animal interaction (HAI) by examining 1) the causal effects of animal assisted interventions (AAIs) in preventing or reducing the physiological ramifications of social and academic stress in youth and college students and 2) assessing the quality of dyadic and triadic interactions during AAIs to capture mediating pathways underlying effects on humans and animals using observational data.
Working with equine and canine programs, I conduct randomized controlled efficacy trials in real-life settings to examine the effects of AAIs on aspects of individuals’ emotion regulation with an emphasis on activity of the Hypothalamic Pituitary Adrenal (HPA) axis as measured through salivary cortisol. I also analyze video recorded interactions of AAI participants (i.e., canine handlers, equine specialists, program facilitators, participants, canines, equines) to capture the quality and quantity of interactions for measurement development aimed at understanding pathways underlying effects of AAIs on human and animal wellbeing.
My work is situated in a prevention science perspective, includes basic and applied approaches drawing from literatures of human development, anthrozoology, animal assisted intervention, animal science and behavior, developmental psychoneuroendocrinology, psychometrics as well as program design, implementation and evaluation
Current Research Projects
The PAWs4US – Pet-Assisted Wellbeing for University Students:
The PAWs4US study is randomized controlled trial examining the effects of a college-based, animal-assisted drop-in program on first-years students’ adjustment as they transition to college. The main goals of the study are to understand to what extent students are attached to their family pet; to what extent that attachment and subsequent separation influences their behaviors related to academics and self-care throughout their first semester on campus; and whether these behaviors are adaptively influenced by regular access to human-animal interaction throughout the semester.
PETPALS – Pets for Promotion of Academic Life Skills:
Funded by MARS/WALTHAM, the PETPALS study is a randomized controlled trial examining the effects of college-based, animal-assisted stress prevention programs on human and animal participants. The main goal of this study is to examine the causal effects of infusing various levels of HAI (Human Animal Interaction) on college students’ executive functioning, motivation and learning, mental health symptomatology (anxiety, perceived stress, depression, and worry) and stress-related physiology (diurnal and momentary cortisol and alpha-amylase production). Another goal is to better understand the effects of participation in HAI programming on stress behavior of emotional support animals, and the role played by the quality of HAI on human and animal outcomes.
PATH to Success Study
Inspired by the desire to prevent the development of stress-related child adjustment problems through animal-assisted, after-school programming, this NIH/Mars-Waltham funded, randomized controlled trial examines the efficacy of an 11-week, equine facilitated learning (EFL) program to strengthen adaptive diurnal activity of the HPA axis (measured through repeated measures of salivary cortisol) and enhance social competence of 10-15 year-old adolescents.
Pet your Stress Away Study
This randomized control trial examines the efficacy of an animal-assisted stress reduction program conducted at a college campus in the week leading up to final exams examining effects of a 10-minute session of canine and feline petting on students’ momentary emotion, perceptions of stress and momentary cortisol levels.
Physiology and Emotion during Human Equine Interaction
This study examines the diurnal and momentary activity of adolescents’ cortisol and alpha-amylase levels and their emotional and behavioral responses to various equine facilitated learning (EFL) program activities.
