Questionnaire No. 3

Prior to the 3rd questionnaire

About 3 years separate the second from the third questionnaire. 

During these years the participants were contacted on several occasions in order to update their contact information. This allowed us to stay in touch with them and to send them a little something for their birhtday. 

The 3rd questionnaire

This stage consists in filling in another questionnaire online (a hard copy can be sent by post if wished) during about 45 - 60 minutes.

This questionnaire is very similar to the previous ones. It also is about the participants' socioprofessional and family background, their consumption of alcohol, cannabis and other drugs, as well as their personality and behavioral addictions like, for example, gambling.

The participation is rewarded with a gift voucher of CHF 50.-, which is sent shortly upon completion of the questionnaire.

Participants are invited to fill in this questionnaire by email. In this email, they find a personal link to the online questionnaire. Those who prefered to fill in a hard copy could get it by post with a postage prepaid envelope.
