Infant and Toddler Quality of Life Questionnaire (ITQOL)

The ITQOL is a generic parent-report instrument developed by Landgraf et al. in 1997 to measure health-related quality of life in infants and toddlers aged 2 months to 5 years. Addressing the developmental uniqueness of the very young, the ITQOL captures health-related functioning across domains relevant to early childhood: physical growth and development, respiratory functioning, sleep patterns, emotional security, parental time and emotional burden, and family social functioning. A 97-item full form and 47-item abbreviated form are available, enabling comprehensive or brief assessment depending on clinical context.
