Kapuscinski’s interests focus on the treatment and prevention of mental health issues in adults, and college students in particular. More recently she has targeted these interests  on the impact of the COVID-19 pandemic on young adults.

Her research involves the treatment of mood, anxiety and obsessive-compulsive disorders, as well as other concerns that are particularly relevant to the young adult population, including body image and disordered eating. Kapuscinski also specializes in the conceptualization and measurement of spirituality and religiousness, and in particular the meaning of these terms within the college student population.

Kapuscinski is a licensed psychologist in the State of New York and a member of both the American Psychological Association (APA) and Association of Psychology Training Clinics (APTC).
