246 Dutch participants aged 8, 10, 12, 14, and 16 years were presented with the Strength of Identification Scale (SoIS; Barrett, 2007) and the National Identity scale based on Cultural and Historical achievements (NICH; derived from the NATID, Keillor & Hult, 1999). The study aimed to examine the extent and nature of Dutch children and adolescents' identification with The Netherlands and to explore whether changes in aspects of national identification are evident across age. Already at age 8 years children identify themselves with the Dutch nation and with increasing age national identification becomes primarily determined by the extent that participants consider themselves to be Dutch and show positive affect towards the Dutch nation. Identification on the basis of cultural and historical achievements of the Dutch people became less evident following the age of 10 years although Dutch historical and cultural achievements contributed significantly to the extent of national identification.
