Health related quality of life (HRQoL), defined as the patients' own evaluation of their health status, is an important criterion in evaluating health and health care. Until now, few systematic attempts have been made to develop instruments to assess HRQoL in children. For this reason, the aim of the study was to evaluate the psychometric performance of the TNO-AZL-Child-Quality-Of-Life (TACQOL) questionnaire; a 56-item, generic, multidimensional HRQoL instrument for children aged 5-15 years, to be completed by parents. The parents of 77 patients, aged 5-15, who were visiting the paediatric outpatient clinic of Leiden University Medical Centre consented to participate in the study and to complete the TACQOL. The results indicated that Cronbach's alpha value for reliability of the TACQOL scales, range from .71 to .89, and that the correlation coefficients among scales were low, indicating the independence of the scales. The scales structure was confirmed in principal component analysis. Only a minority of parents indicated health status problems in their child an also reported negative emotional feelings contingent on such problems. It is concluded that the psychometric performance of the TACQOL is good, and the instrument may be used to assess group differences in HRQoL in children. In defining HRQoL, relevance of the distinction between health status and negative emotional reactions to health status problems is supported by the results of the study.
