[Evaluation of the quality of life of infants and very young children: validation of a questionnaire. Multicenter European study].

Unlabelled: In the last few years, evaluating quality of life in children has become possible using specific instruments; nevertheless, there is still an unsolved issue concerning the earliest ages, when the child is not able to give his/her own opinion. QUALIN, a new instrument designed to assess an infant's quality of life (between the ages of three months and three years) was developed from the study of spontaneous criteria used by parents or caregivers (paediatricians or nurses) when they think about the quality of life of a baby (preliminary survey including 800 open-ended questionnaires).

Patients And Methods: One thousand four hundred and twelve children under the age of three were included in this validation study.
