Background: The Dutch TRAILS-study focuses on the development of youth from early adolescence into adulthood. An important aspect of this development is the development of anxiety. Little was known about typical development of symptoms of anxiety over adolescence. Aim: To describe normative development of anxiety over adolescence, as well as risk indicators for high levels of anxiety. Methods: Studies were imbedded in TRAILS, a large cohort study following children (10y) into adulthood (25y). Results: Our studies show that on average levels of anxiety decrease in early adolescence and subsequently increase in middle or late adolescence, depending on the subtype of anxiety. We found child, parent and peer factors at age 10-12 that were related with higher anxiety levels. Some, e.g., parenting style, were related with higher anxiety only in early adolescence, whereas others, e.g., victim of bullying by peers were related with higher anxiety levels throughout adolescence regardless of stability of victimization. Conclusion: Our studies contribute to a better understanding of normative development of anxiety over adolescence.
