Colin T. Mahoney, Ph.D.
Mixed Methods Promoting Wellness and Recovery (MPWR) Lab
Dr. Mahoney joined the UCCS Psychology Department in the Fall of 2021. He is a UCCS alum (M.A. in clinical psychology), and completed his doctoral training in clinical psychology at Idaho State University with specialized training in experimental methodology within the context of behavioral economics (i.e., impulsive choice and risk-taking). Dr. Mahoney completed his predoctoral clinical internship at Geisinger Medical Center in Danville, PA as a Behavioral Medicine Intern, and his NIMH-funded T32 postdoctoral research fellowship at the National Center for PTSD, VA Boston Healthcare System, and Boston University School of Medicine.
His research focuses 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 interpersonal violence (i.e., sexual violence, intimate partner violence [IPV], community violence) and among male and female Veterans following exposure to combat trauma and/or military sexual trauma (MST) through (1) experimental, (2) prospective studies, and (3) qualitative studies. The intention is to investigate these processes to inform, enhance, and develop evidence-based assessments and treatments for PTSD and comorbid SUDs. Dr. Mahoney is particularly interested in using this knowledge to develop behavioral assessment tools, brief face-to-face interventions, and digital health interventions.
