Dr. Arroyo's research interests are in health, interpersonal, and relational communication. Her research falls into three lines of inquiry: 

1.Interpersonal Communication and Body Image 

    (e.g., negative body talk, disordered eating)

2.The Intergenerational Transmission of Mental Health 

    (e.g., parent-child depression, loneliness, anxiety)

3.Intergroup Attitudes within Interpersonal Relationships 

    (e.g., sexism, weightism, racism) 

Together, her research emphasizes some of the ways that communication in close relationships is associated with individuals’ physical, mental, and social well-being, and it also highlights that the messages reinforced within these relationships have the ability to uphold or challenge dominant social discourses, ideals, and expectations.
