RESEARCH
Project Datasets
Good science depends on free and forward sharing of data. This is why me and my colleagues have decided to open up our data vaults the coming period. Currently, we grant access to two datasets from either finished or ongoing longitudinal research projects: SODA and SEX-Y. Below is a short description of each dataset, together with links to relevant measure overviews, codebooks, and data request forms.
Social Development Of Adolescents (SODA) Study
The Social Development of Adolescents (SODA) study is a three-year, three-wave longitudinal study on the social development of Dutch adolescents aged 12 to 18. The data were collected in 2005, 2006, and 2007. All adolescents taking part in this study were students enrolled in secondary schools in The Netherlands. The questionnaires were administered in classrooms of 28 high schools in a 100-km radius from the city of Nijmegen. At baseline, 2,425 adolescents (1,216 males, 1,209 females) participated, who were mostly from an indigenous Dutch background (88.5%) and with a mean age of 14.36 years. The complete three wave longitudinal sample consists of 779 adolescents—biased attrition was of minimal effect. Adolescents self reported on the quality of their bonds with parents, best friends, and romantic partners and various other measures, amongst others of internalizing and externalizing problems.

Sexual Development of Youths (SEX-Y) Study
The Sexual Development of Youths (SEX-Y) study is a 2-year, four-wave longitudinal study on you guessed it—the sexual development of youths aged 12 to 18. The first wave of data collection took place in 2009, the second, third and fourth wave after 6, 12, and 18 months respectively. Paper-and pencil survey data were collected from third year (U.S. 9th grade equivalent) students attending seven high schools throughout The Netherlands. Data collection took place in a classroom setting. At baseline (T1), 658 students completed the questionnaire. Because class composition changed between T2 and T3, there was some attrition in sample size, and the final 3-wave sample consisted of 444 adolescents (230 girls, 51.8%). Analyses of the key variables showed no strong biases in attrition. Mean age was 14.46 years, with most participants coming from a Dutch background (83.3%), enrolled in vocational education programs and reporting a heterosexual orientation (89.9%—with 3.2% homosexual orientation, 0.9% bisexual orientation, and 6.0% unsure of orientation).
