title: [Methodological background and descriptive features of the ESPAD 2011 Study (European School Survey Project on Alcohol and other Drugs) in Hungary].
abstract: OBJECTIVE
  The aim of the ESPAD (European School Survey Project on Alcohol and other Drugs) study - launched in 1995 and repeated in every four years - is to collect representative data on alcohol and drug consumption patterns of the 16 year old population, in as many European countries as possible.
  
  
  METHODS
  The survey followed standardized methodology to gain comparable data in every participating country. Students fill in the self-report questionnaire during a school lesson. Beside the compulsory core-question blocks, the Hungarian survey in 2011 contained questions on behavioral addictions (online gaming, internet, eating disorders and gambling) as well. All classes were included into the sample pool, where at least 10% of the students were born in 1995. Data collection took place between 1-20 March 2011. The sample was representative in terms of type of school; class and geographic location.
  
  
  RESULTS
  Data was gathered from 370 classes and resulted in 8570 questionnaires. Only 0,96 percent of the total collected data was unreliable. Obtained data is valid and reliable; and can be compared to data from previous years, as well as to data from other ESPAD countries. Representative data on behavioral addictions is highly valuable, because our current knowledge is limited on this domain.
