Verrips, G.H., Fekkes, M., Theunissen, N.C.M., Brugman, E., Veen, S., Koopman, H.M., Wit, J.M., & Verloove-Vanhorick, S.P. (1997). The TAIQOL: a generic health-related quality of life measure for 1 -4 year olds. 4th Annual Conference of the International Society for Quality of Life Research (ISOQOL), Vienna, Austria, 4-9 November, Quality of Life Research, 6(7/8), 736.


The purpose was to evaluate the psychometric performance and criterion validity of the TAIQOL. The questionnaire was needed in evaluating health-related quality of life (QoL) outcome in clinical research on children with a very low birth weight (VLBW). Health-related QoL was defined as health status plus affective responses to problems in health status. Health status was defined multidimensionally to encompass 13 dimensions. The TAIQOL is completed by a parent in approximately 10 min. Parents of 106 VLBW children, aged 1 – 4 years, completed the TAIQOL as well as parents of 363 children in the open population. The psychometric performance was evaluated by Cronbach's a and by the percentage of items with a higher itemrest Pearson correlation coefficient (r) than item-other scale rs. The multidimensionality of health-related QoL was evaluated by factor analysis and by rs between the TAIQOL scales. The criterion validity was evaluated by analyses of variance. The Cronbach's as were 0.52 – 0.89. Ninety-six percent of item-rest rs were higher than item-other scale rs. Ninety-four percent of items loaded higher on their proper factor than other factors. The rs between TAIQOL scales were 0.04 – 0.50. The percentage status of problems per scale that led to negative affective responses ranged from 21 to 86%. As expected, VLBW children, children with a chronic disease and children under medical treatment had worse health-related QoL than other children. The psychometric performance of the TAIQOL was good. The findings support the multidimensional definition of healthrelated QoL. The fact that on average only 39% of health-related problems led to negative emotional consequences indicates the essential importance of assessing subjective emotional appraisal of health status. The criterion validity of the TAIQOL was good. In conclusion, the TAIQOL is a suitable instrument in assessing health-related QoL in groups of very young children.
