My main area of interest is internet and phone based behavior change programs, particularly, alcohol early interventions and smoking cessation interventions. I’m interested in the development of treatment rationale, how to develop, test and evaluate, and the working mechanisms of such technology based intervention programs. My theoretical interests are health psychology, behavior change models/theories, self-regulation theory, relapse prevention, harm-reduction, mechanisms of change in addictive behavior, addiction in a public health perspective and intervention mapping.


Main projects at SERAF 

I'm currently the principal investigator on two large projects at SERAF - one alcohol project that is in its final stage (reporting), and one recently started smoking cessation project:

  • Developing and testing the efficacy of a lapse management system for smoking cessation (started September 2013, runs through 2017).
  • Evaluation of an alcohol early intervention (Balance), delivered by the Internet and cell-phones (are in the final reporting phase).

Additionally, I'm a co-investigator on internal and external projects:

  • Web and mobile smoking cessation, Oregon Research Institute.
  • Mamma Mia - a web based intervention to reduce the risk of postpartum depression and enhance subjective well-being.
  • Projects, lead by Ayna B. Johansen at SERAF, concerning motivation for change and processes of change in addictive behaviors.
