HBSC ESPAÑA

The 2014 edition of the Spanish HBSC study is supported and financed by the Ministry of Health, Social Services and Equality.

In this edition, data were collected from over 30,000 boys and girls between the ages of 11 and 18 years old, in a total of 402 schools.

The sample method (random multistage sampling stratified by conglomerates) allowed for generalization of the results on a national level. Likewise, the results are representative with respect to age (11-12, 13-14, 15-16 and 17-18 years old), region and type of school (public or private).

The random sample of participant schools is taken from a census provided by the Ministry of Education in which all Spanish schools are included.

Since the 2010 Spanish HBSC edition, new information and communications technologies (ICT) have been included in the data collection process. Specifically, Internet was used as a digital support and as a tool that allowed students to complete and send in the questionnaire.

The questionnaires include a set of standard questions used by all 40 countries that participated in this edition of the study, as well as a set of specific questions selected by the Spanish HBSC team and the Ministry of Health, Social Services and Equality.

The standard questions for the international HBSC network are subjected to a process of translation/back-translation to ensure parity between languages.

As in all of the prior editions, the 2014 HBSC questionnaire explores a wide range of subjects that not only focus on lifestyles, but also cover different measures exploring psychological adjustment and quality of developmental contexts (family, school, peer).

The questionnaires were administered during school hours under the supervision of teachers whom had received clear and concise instructions about the data collection process. The students were guaranteed complete anonymity.
