Andrew Lac, Ph.D.
Prof. Andrew Lac joined the UCCS Psychology Department in 2015. Previously, he was affiliated with Claremont Graduate University as research faculty and Loyola Marymount University as visiting faculty.
Dr. Lac’s research focuses on the psychology of substance use and addictive behaviors. His topics of interest include alcohol, marijuana, other substances (almost anything that could be ingested or inhaled), sexual activity, pornography, internet compulsions, and other addictive behaviors. These topics are examined from various perspectives, including attitudes and beliefs, motivations and expectations, feelings and emotions, risk factors, protective factors, prevention, brief interventions, peer norms, family practices and history, attachment and dyadic relationships (e.g., best friends, parent-child, siblings, twins), racial disparities, behavioral genetics, and the role of social media. Furthermore, he publishes on scale development and validation applied to these domains.
