Sarah N. Arpin

Sarah Arpin is an Associate Professor of Psychology at Gonzaga University, and leads the Social Emotions, Relationships, and Health Research Lab. She received her Ph.D. in Applied Psychology from Portland State University in 2015, with a major in Social Psychology and a minor in Quantitative Methods. She received her M.S. in Applied Psychology from Portland State University in 2012, and her B.A. in Psychology from Gonzaga University in 2010.

Dr. Arpin’s research focuses broadly on the intersection of social relationships and health. One particular area of focus has been on the experience of loneliness, and the impact of loneliness on social interactions, social decision-making, and health behavior (e.g., alcohol use). She has explored these processes via daily surveys, online surveys, and experimental lab-based methods. Dr. Arpin also studies intimate relationships, and the interdependence of emotions and health behavior within romantic couples. A current line of her research explores associations among self-disclosure, loneliness and sleep within romantic couples.

As an applied social psychologist, Dr. Arpin also seeks to engage with the Spokane community in her work. Dr. Arpin is currently collaborating with a colleague, Dr. Monica Bartlett, in a daily study of loneliness, gratitude, and health among older adults living in independent living facilities in the greater Spokane area.
