Andrew Lac, Ph.D.
Professor Andrew Lac joined the UCCS Psychology Department in 2015. Previously, he was affiliated with Claremont Graduate University as Research Professor and Loyola Marymount University as Visiting Professor.
Dr. Lac’s research focuses on the psychology of substance use and addictive behaviors. His research interests include alcohol, marijuana, other substances (almost anything that could be ingested or inhaled), sexual activity, 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, social and peer norms, family practices and history, attachment security and interpersonal relationships (e.g., best friends, parent-child, siblings, twins), racial and cultural disparities, behavioral genetics, and the role of social media. Furthermore, he publishes on scale development and validation (EFA, CFA, and IRT) and the evaluation of the psychometric properties (factor structures, reliabilities, and validities) of measurement scales as applied to these areas.
Dr. Lac served as the Interim Director of Psychological Science Training for the MA program.
