The BELLA study measures mental health, behavior and health-related quality of life among children, adolescents, their families and young adults in Germany. The longitudinal BELLA study is the mental health module of the German National Health Interview and Examination Survey among Children and Adolescents (KiGGS), conducted by the Robert Koch Institute between 2003 and 2006 (basis) and between 2009 and 2012 (wave 1).
The BELLA cohort comprises a representative subsample of the KiGGS Survey of 3.000 children, adolescents and their families as well as young adults. In addition to the baseline assessment (2003-2006), the BELLA cohort was followed-up in four additional waves conducted in 2004 to 2007, 2005 to 2008, 2009 to 2012 and 2014 to 2017. Data was collected through telephone interview and subsequent questionnaires or online survey by parent report and above 11 years by additional self report. The assessed information provides evidence for the prevalence and determinants of mental health problems in childhood and adolescence in Germany.
