Summary of development: The ITQOL is a multidimensional measure that was developed for a broad age continuum so that scores could be tracked over time. The instrument is a parent-reported measure, and it complements the Child Health Questionnaire, an instrument for ages 5 and older with more than 72 translations. It adopts the seminal World Health Organization’s definition of health (i.e., a state of complete physical, mental, and social well-being and not just the absence of disease) and developmental guidelines used by pediatricians as its conceptual framework. By utilizing items specific to infant development and a conceptual framework similar to but not identical to the CHQ, the ITQOL allows for the continuous measurement of health-related quality of life outcomes across the infant/child continuum. (Landgraf 2013).
Items of the long version of ITQOL (97-103 items) were reduced to 47 items for the short version of ITQOL. The short version was developed using data in Dutch. Here, we only include testing information from English versions of the questionnaire.
Two versions: Long (97 items) and Short (47 items)
