Basic description

The Infant Toddler Quality of Life Questionnaire™ (ITQOL) was developed for use in infants and toddlers from 2-months-to-5 years of age.

There are two versions of the ITQOL - the 47-item short-form (ITQOL-SF47) and the 97-item full-length version (ITQOL). They measure the same concepts - just with fewer items. 

The ITQOL complements the Child Health Questionnaire (CHQ) (see related COA instruments tab)
