Samenvatting

Doel. Vaststellen van de psychometrische eigenschappen van de Impact of Weight on Quality of Life-Kids (IWQOL-Kids), een meetinstrument om met lichaamsgewicht samenhangende kwaliteit van leven te meten bij adolescenten van 11 tot 19 jaar.

Methode. De IWQOL-Kids werd door 104 adolescenten ingevuld en van hen werden de lengte en het gewicht gemeten. De Pediatric Quality of Life Inventory (PedsQL), een vragenlijst om algemene kwaliteit van leven te meten, werd afgenomen om de convergente validiteit te bepalen. De gevoeligheid voor verandering na een interventie werd vastgesteld.

Resultaten. Op drie van de vier schalen was de interne consistentie goed (Cronbachs alfa 0,81-0,82) en voor één schaal redelijk (Cronbachs alfa 0,66). Het patroon van correlaties met schalen van de PedsQL ondersteunde de validiteit. De IWQOL-Kids was in staat te discrimineren tussen gewichtsklassen en bleek gevoelig voor verandering na een interventie.

Conclusie. De IWQOL-Kids lijkt een valide meetinstrument voor het meten van met lichaamsgewicht samenhangende kwaliteit van leven van adolescenten.

Summary

Aim To evaluate the psychometric qualities of the Dutch translation of the Impact of Weight on Quality of Life-Kids (IWQOL-Kids), a measure of body-weight-related quality of life in adolescents (age 11-19 years).Method. The IWQOL-Kids was completed by 104 adolescents for whom weight and height were measured. To examine convergent validity, associations with the Pediatric Quality of Life Inventory (PedsQL), a generic health related quality of life questionnaire, were determined. The sensitivity to change was established after an intervention.Results. Internal consistency coefficients were high for three out of four scales (Cronbach’s alpha 0.81-0.82) and moderate (0.66) for one scale. Convergent validity was confirmed by the pattern of correlations between scales of the IWQOL-Kids and the PedsQL. The IWQOL-Kids discriminated among weight classes and showed responsiveness after an intervention.Conclusie. Results suggest that the IWQOL-Kids is a valid instrument to measure weight-specific quality of life in adolescents.
