Mixed Methods Promoting Women's Recovery (MPWR) Lab

We are a research team focused on identifying risk, maintenance, and protective factors for the symptoms and diagnosis of posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) among women following exposure to intimate partner violence (IPV), campus sexual assault, and community violence. We use mixed methodology including experimental, qualitative, and prospective designs to pursue and promote clinical knowledge surrounding these forms of trauma-related psychopathology. The intention of our work is twofold: (1) to discover malleable targets of treatment to improve functioning and quality of life for women who have experienced gender-based interpersonal violence; and (2) to inform public policy and community-based prevention efforts.

We invite you to explore our lab website, including learning about our team members and collaborators, our current research projects, and accessing full-text publications.

The Mixed Methods Promoting Women’s Recovery (MPWR) Lab is directed by Colin T. Mahoney, Ph.D., and is part of the Department of Psychology at Western New England University.

Lab Members

  • Colin T. Mahoney, Ph.D.

    Director, MPWR Lab • Colin.Mahoney@wne.edu

    Dr. Mahoney is an Assistant Professor in the Department of Psychology at Western New England University. He received his Ph.D. in clinical psychology from Idaho State University in 2018, and then completed a two-year NIMH-funded T32 postdoctoral research fellowship at the National Center for PTSD, VA Boston Healthcare System, and Boston University School of Medicine. As a clinical research psychologist, he works with a team of student researchers to study trauma among women in the form of interpersonal violence (e.g. IPV, sexual assault, community violence). These forms of violence disproportionately affect women, particularly women of color and sexual minority women. Dr. Mahoney is particularly interested in understanding the etiology, course, and sequelae of PTSD and comorbid SUDs among women. He's also interested in developing and validating behavioral assessments of these clinical disorders to aid with diagnosis and evidence-based interventions. As an educator, Dr. Mahoney teaches undergraduate courses including Research Methods and Sexuality/Sexual Assault in Society. He also mentors and advises undergraduate students. In his free time, Dr. Mahoney likes to go hiking and spend time outdoors with his wife, Stephanie, his infant daughter, Rowan, and his dog, River.
