The Spanish KIDSCREEN follow-up study reassessed the Spanish baseline sample (n = 840) of the European KIDSCREEN study 3 years later (2006) The alms of tills paper were to describe the KIDSCREEN follow-up Study and the pilot test. and to analyze participation rates and representativeness Instruments included the KIDSCREEN-52 HRQoL measure and a set of scales. Including the possible explanatory variables Focus groups and individual interviews were carried out in a pilot test. Participants were compared with non-participants at baseline. and also with Eurostat census data Twenty-two out. of 24 subjects were interviewed in the pilot test Fifteen items needed to be modified after the pilot test Participation rate reached 54% (n = 454) Participants (mean age = 12 71 years old) were on average 6 months younger than non-participants (p=003), and ROM more educated families KIDSCREEN follow-up instrumentation seems adequate for collecting factors with potential influence on HRQoL. Follow-up respondents' representativeness seems to be acceptable. (C) 2009 The Association for Professionals in Services for Adolescents Published by Elsevier Ltd All rights reserved.
