Areas of Emphasis
My research takes a biobehavioral approach towards the study of human animal interaction and human development by examining the effects of animal assisted programs in reducing the physiological ramifications of social and academic stress, with an emphasis on strengthening adaptive functioning of the Hypothalamic Pituitary Adrenal (HPA) activity in children, adolescents and college students. While my research is broadly situated within a prevention science perspective, it is also informed by the interdisciplinary fields of human development and learning science through its emphasis on the social-psychological foundations of human development and learning, as well as on the design and evaluation of programs that enhance learning environments. My work includes basic and applied approaches and draws from literatures of child and adolescent development, animal assisted intervention and therapy, developmental psychoneuroendocrinology as well as program design, implementation and evaluation.
Current Research Projects
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.
This is a pilot project examining an equine-assisted version of the Strengthening Families Program (SFP), a nationally and internationally recognized, evidenced-based parenting and family skills training program for high-risk and regular families. This mixed-methods project examines the design, implementation and evaluation of SFP-E, including a clinical trial on the effects of family-level, equine facilitated learning activities on the quality of family interactions and their physiological, behavioral and emotional correlates.
Family Life and Stress Study
The Family Life and Stress Study – funded by the National Center for Family and Marriage Research (NCFMR) – examines the role of child exposure to interparental discord and the dysregulation of child and adolescent cortisol and alpha-amylase levels.
