Abstract

the objective of this study was to assess the validity of a mobility questionnaire (MobQues) that was developed to measure parent-reported mobility limitations in children with cerebral palsy (CP). the parents of 439 children with CP (256 males and 183 females; age range 2-18y; Gross Motor Function Classification System [GMFCS] levels I-IV) completed the mobility questionnaire (MobQues). To assess content validity, we linked all meaningful concepts of the MobQues items to the International Classification of Functioning, Disability and Health (ICF). To assess construct validity, we compared the total scores of the two versions of the MobQues (MobQues47 and MobQues28) according to GMFCS level, and determined Pearson's correlation coefficient (r) with the Gross Motor Function Measure-66 (GMFM-66). content validity was demonstrated by the fact that 46 of the 47 MobQues items were linked to categories in the 'Mobility' chapter of the ICF. Construct validity was demonstrated by the finding that MobQues scores decreased with increasing GMFCS levels (p<0.001). In a subgroup of 162 children, positive correlations were found between total scores and the GMFM-66 (MobQues47, r=0.75; MobQues28, r=0.67, p<0.001). the results of this study pr...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
