The new data collection within the ABCD-study has started. This will be phase 4. In comparison to phase 3 some things have changed: for the moment, collection will only focus on questionnaires and some cognitive tasks on the computer. For the first time the ABCD children will be asked to fill out a questionnaire themselves. Moreover mothers, fathers and teachers will be asked to fill out a questionnaire. The ABCD study follows the current trends and therefore the questionnaires for this phase can be completed online, however paper questionnaires can be requested by contacting the ABCD- study.
In phase 4 we will work with the ADAPT group of the developmental psychology department of the University of Amsterdam and with IRAS . Finally, we will cooperate with the Sarphati Institute to conduct more research on obesity and its consequences at a young age.
More information about phase 4 can be found at the homepage of phase 4 or in the flyers, which are available online in Dutch, English and Turkish. For question and/or remarks, please do not hesitate to contact us through our contactform or through our contact details below.
