CONAMORE is an ongoing longitudinal study of Dutch adolescents that examines their personality and identity, their relationships with parents and peers as well as their emotional and behavioural states (Meeus et al., 2002). Between 2001 and 2006 five annual waves have been conducted. From the first wave onwards, the sample was designed to contain two age cohorts, namely early and middle adolescents. The total adolescent sample consisted of 1,313 respondents and demonstrated a very small attrition (1% from wave 1 to wave 2, 2.6% from wave 2 to wave 3, 1.4% from wave 3 to wave 4, 1% from wave 4 to wave 5). A group of 200 ethnic minority adolescents has been included in the sample.
