Background The Child Health Questionnaire (CHQ) is a widely used instrument for measuring health‐related quality of life covering both the physical and psychosocial domain. This study examined the responsiveness of the D utch CHQ 50‐item Parent Form ( PF 50) in a sample of adolescents with chronic non‐specific pain and/or fatigue. Method Five different methods were used to calculate the responsiveness for the physical ( PhS ) and psychosocial ( PsS ) subscale of the CHQ ‐50: standardized response mean ( SRM ), pooled effect sizes ( ES s), standard error of measurement of agreement ( SEM agreement ), minimal detectable change ( MDC ) and the area under the receiver operating characteristics ( ROC ) curve. For data analysis, the population was divided into two groups based on the parent's global perceived effect of treatment: a changed group (A) and an unchanged group (B). Results The responsiveness analyses were performed including 92 adolescents (88.0% girls; mean age 16.4 years). The SRM s are 2.89 and 1.01 for the PhS and PsS , respectively. Large ES s are found for group A ( PhS = 3.30; PsS = 1.16). The method used for calculating SEM agreement results in a score of PhS = 18.92 and PsS = 11.39. The MDC s of PhS and PsS are 52.45 and 31.57, respectively. The area under the ROC curve ( AUC ) for PhS = 0.79 and for PsS = 0.64, and the corresponding optimal cut‐off points are 21.1 and 7.0. Conclusion Using the methods SRM , ES and AUC , the responsiveness of the CHQ ‐ PF 50 in adolescents with non‐specific chronic pain or fatigue treated in a rehabilitation clinic is adequate for the physical scale and moderate for the psychosocial scale.
