A convenience sampling was used and the sample was four to six year old children. The question list was sent out from the kindergartens in Hafnarfjörður and in the North West of the country to parents/guardians of the kindergarten students.
Notað var hentugleikaúrtak þar sem úrtakið var fjögurra til sex ára leikskólabörn en spurningalisti var sendur út frá leikskólum í Hafnarfirði og á Norðurlandi vestra til foreldra/forráða-manna barna leikskólanna.
