Academic interests:

Health psychology, behavior change, lifestyle, self-regulation, relapse prevention, addiction, smoking cessation, early interventions for alcohol, and the "intervention mapping" approach to designing intervention programs.

Web- and phone-based behavior change interventions: what are the working mechanisms and the optimal design; which techniques and components should be included; what is the eHealth equivalent to the working alliance in face-to-face therapy; and how should eHealth interventions be implemented into real life?


Ongoing projects:

Testing the efficacy of a lapse management system in an online smoking cessation intervention:
  • Primary development of intervention, as well as formative evaluation, took place from fall 2013 and through 2016.
  • An ongoing randomized-controlled trial will test the efficacy of the lapse management component of the intervention.
  • Funded by The Norwegian Research Council (Public Health programme), and runs from September 2013 until spring 2018.
  • A PhD-student (doktorgradsstipendiat), Marianne Therese Smogeli Holter, are full-time employed on the project from february 2014 until spring 2018. Her main contributions are twofold: First, she has already contribute heavily to writing the intervention contents - through an intervention mapping process. Second, she has conducted a series of qualitative interviews with end-users. The interviews was impomrtant for the formative evaluation and the subsequent revisions of the intervention. The main purpose of the interviews is however a grounded theory study of how users relate to the program. (E.g., does this relating resemble aspects of the therapeutic relationship or working alliance in face-to-face conselling?)
  • Role: PI.

Evaluating a web-based alcohol early intervention (Balance):

  • The effectiveness, feasibility and acceptance is evaluated in several studies: Two RCTs, qualitative interviews with program users, and a theoretical paper describing intervention rationale. Final paper was published 2017. Some papers are still "in the pipeline".
  • Funded by The Norwegian Centre for Addiction Research and The Norwegian Research Council.
  • Project funding ran from January 2010 through August 2013.
  • Role: PI.

Evaluating a web-based program to reduce the risk of postpartum depression and enhance subjective well-being (Mamma Mia):

  • A description of the treatment rationale is underway, and the recruitment to an RCT testing the efficacy of the intervention is running from fall 2013. A paper on formative evaluation of the intervention was published in spring 2013.
  • Funded by the The No rwegian Research Council - July 2012 through June 2015
  • The projectleader is Silje Marie Haga at RBUP.
  • Role: Co-investigator.

Motivation for change and processes of change in addictivie behaviors:

  • A line of research lead by Ayna B. Johansen, at the Norwegian Centre for Addiction Research.
  • Approach: Qualitative interviews are analyzed using a grounded theory approach.
  • Funding: various sources.
  • Role: Co-investigator.

Web and Mobile Smoking Cessation Intervention:

  • Testing whether providing program content via mobile phones increases long-term tobacco abstinence among participants in a best-practices Web-based smoking cessation intervention.
  • Principal investigators are Brian Danaher and John Seeley, Oregon Research Institute.
  • Funded by the (US) National Cancer Institute, from April 2013 through February 2017.
  • Role: Co-investigator.
