Emerging adulthood is recognized as a recent and developmentally distinct phase in the life-course, characterized as a period of identity exploration, of instability, being self-focused, feeling in-between, and an age of possibilities. To measure the subjective experience of emerging adulthood Reifman, Arnett, and Colwell developed the Inventory of the Dimensions of Emerging Adulthood (IDEA). While a series of studies demonstrated the applicability of the five dimensions of emerging adulthood and effectiveness of IDEA for measuring these in US samples, results from non-US samples revealed important cultural differences in how emerging adulthood is experienced. The current study tests the extent to which emerging adulthood is experienced by Dutch young people, and the relevance and validity of the IDEA for a general urban population sample from the Netherlands. We examined differences between socioeconomic and ethnic groups within this population. The results revealed that certain aspects of the Dutch emerging adulthood experience are different from the USA. In addition, there are small but significant differences between Dutch socioeconomic and ethnic groups in how this period of life is experienced. Economic and cultural explanations for these differences are discussed.
