Kristina Phillips, PhD, is a clinical psychologist at CIHR at Kaiser Permanente Hawaii. She completed her PhD in Clinical Psychology and Behavioral Medicine from Bowling Green State University and a post-doctoral fellowship at the Center for Alcohol and Addiction Studies at Brown University. Dr. Phillips joined CIHR in 2019 and has expertise in substance use and addiction. Her primary research interests focus on examining high-risk substance use practices that contribute to negative health outcomes (e.g., HIV, HCV, bacterial infections), brief interventions, treatment outcome, and ecological momentary assessment and intervention (mHealth).

Dr. Phillips was recently the principal investigator and co-investigator of two NIDA-funded clinical trials that tested a risk reduction intervention with motivational interviewing components for people who inject drugs in Denver and Boston. Another line of her research program focuses on marijuana use, craving, and psychological co-morbidity in young adults. A project on this topic was recently funded by NIDA and employs ecological momentary assessment to learn about participant behaviors “in the moment” using smartphones. Dr. Phillips plans to continue her work on mobile assessment and intervention with substance users engaging in high-risk behaviors.

Before joining CIHR, Dr. Phillips was a professor in the School of Psychological Sciences at the University of Northern Colorado, where she developed her research program, taught undergraduate and graduate courses, and mentored students in independent research

The vision of the proposed Addiction Research Network (ARN) node of the Clinical Trials Network is to expand access and transform substance use treatment through integrating it into real-world medical settings. Through its network of 15 learning healthcare systems and electronic health record data, the ARN node will conduct research that identifies and implements multiple effective treatment option for patients. As part of the CTN, the ARN node will help build the infrastructure required for the next era of addiction health services research both nationally and internationally.
