Development and psychometric properties of the Chinese language version of the TAPQOL: a health-related quality of life instrument for preschool children.

The objectives of this study were to assess psychometric properties of the Mandarin version of the TZO-AZL Preschool Children Quality of Life (TAPQOL) questionnaire in Taiwanese preschool children. Two groups of children, a very low birthweight group (n=118) and a not-very low birthweight group (n=170), were recruited. The internal consistency was acceptable and the correlation coefficients between the 12 subscales were low. Confirmatory factor analysis supported the 12-factor structure. Children with very low birthweight had significantly lower quality of life scores. This instrument may be used in clinical and research applications to investigate quality of life among preschool children.
