Research Interests and Projects

Frøyland’s main research interests include violence and abuse, both within families and among peers, youth sexuality, and crime and other forms of problem behavior among adolescents. He has led several key projects as the Principal Investigator (PI), focusing on societal trends in violence and abuse, long-term outcomes of violent victimization, technology-facilitated sexual abuse, and the public sentiments on justice.

In 2024, Frøyland received a prestigious grant from the Research Council of Norway's call for groundbreaking research for early-career researchers. This grant supports a comprehensive project on youth sexuality, commencing in the fall of 2025, which will investigate how the digitalization of society has influenced youth sexual practices and sexual risks (DIGISEX).

Publications and Data Expertise

Frøyland’s most recent publications cover areas such as childhood maltreatment and revictimization in young adulthood, violence and sexual health, sexting, technology-facilitated sexual abuse, incapacitated sexual assaults, and societal trends in adolescent problem behavior. He has extensive experience in the collection and analysis of quantitative data and was the PI of the YouthViolence 2023 survey. Additionally, he has contributed significantly to surveys such as Ungdata, Young in Norway, and the International Civic and Citizenship Education Study (ICCS).
