Background and activities

I'm a professor in clinical child- and adolescent psychology, co-head at the Dept. of Psychology and co-PI of the Trondheim Early Secure Study (TESS). TESS started in 2007 and comprises a sample of 1,250 children drawn from the 2003 and 2004 birth cohorts and their parents in Trondheim, Norway. The participants were examined when the children were 4 years old and they have been followed up with in-depth interviews, questionnaires, tests, and observations at ages 6, 8, 10, 12, and 14. The seventh wave of data collection (age 16) will be completed by  2021, and the eight wave of data collection (age 18) starts in January 2022.

The goal of the study is to determine the prevalence and course of common mental disorders, physical inactivity, eating behaviours and adiposity, and to detail potential etiological factors.The TESS also aims to describe children’s typical development as well as determinants of individual differences in important aspects of functioning, such as personality, attachment, parent-child relationships, social and academic competence, self-concept, behavioral and emotional regulation, sexuality, cognition, physical activity, Internet gaming and social media use.

My main research areas are children's eating behavior and parental food-practices, overweight, physical activity, sleep/sleep disorders, mental health and social media use.
