The Impact of Weight on Quality of Life – Kids (IWQOL-Kids)© is a validated self-report measure of weight-related quality of life for youth ages 11-19. The four subscales (physical comfort, body esteem, social life and family relations) and total score have strong psychometric properties, discriminate among weight status groups and are responsive to weight change. This measure was jointly developed by Cincinnati Children’s and Quality of Life Consulting, PLLC.

In addition to the self-report version, there is a parent-proxy version that has been evaluated psychometrically and has a similar fee structure (see Nadeau K., Kolotkin R.L., Boex R., Witten T., McFann K.K., Zeitler P., Walders-Abramson N. Health-related quality of life in adolescents with comorbidities related to obesity. Journal of Adolescent Health, 2011 Jul; 49(1): 90-2.).

In addition to a total score, there are scores on four domains:

• Physical Comfort (6 items)
• Body Esteem (9 items)
• Social Life (6 items)
• Family Relations (6 items)

 Scores range from 0 to 100, with 100 representing the best quality of life.
