This study consists of a biannual survey panel. The questionnaire will be carried out in 91 academic centres of Central Catalonia. Central Catalonia is divided into six regions (Anoia, Osona, Bages, Berguedà, Solsonès and Moianès), where there are 165 districts. In this territory, there are 89 Secondary education schools and two academic centres where post-compulsory education is taught exclusively (College-preparatory and vocational training).


The questionnaire used focuses in some health aspects and its related factors: sociodemographic data; health and overall well-being; rest and mood state; eating habits; physical activity and leisure time; new technologies use; use of tobacco, cannabis, alcohol and other drugs; relationships with others and sexuality.

  • Youth Europe Questionnaire
  • Survey on drug use in Secondary education in Spain (ESTUDES)


The DESKcohort questionnaire is a computerized and self-administered survey. It is answered using tablets with internet connection in school’s classrooms. It lasts about 40 minutes and is administered by external staff.
