Translation and validation of Cerebral Palsy Quality of Life Questionnaire-Teen in Hong Kong Chinese population [CP QoL-Teen (HK)]

Abstract

Cerebral palsy (CP) is an early onset, non-progressive, neuromotor disorder. Adolescence is the transition from childhood to adulthood when changes in physical and emotional aspects and self-perception occur further imposing an impact to quality of life (QoL) in individuals with CP. Cerebral Palsy Quality of Life (CP QoL) Teen is a questionnaire examining different domains of QoL for adolescents with CP. This study is aimed at translating and validating self-report and proxy-report CP QoL-Teen (HK). Prior approval of translation has been obtained. Forward and backward translations were performed following standardized translation procedures. Participants and their caregivers were asked to complete self-report and proxy-report CP QoL-Teen (HK), and Child Health Questionnaire (CHQ). Internal consistency and test–retest reliability were assessed by Cronbach’s alpha and intraclass correlation coefficient (ICC), respectively. Concurrent validity was evaluated by Spearman’s rank correlation between subscales of CP QoL-Teen (HK) and CHQ as well as expanded and revised version of Gross Motor Function Classification System (GMFCS-E&R). Ninety-six participants completed the study. Of these, twenty participants completed CP QoL-Teen (HK) twice. Cronbach’s α of CP QoL-Teen (HK) ranged from 0.84 to 0.95 suggesting excellent internal consistency. Moderate to excellent test–retest reliability were demonstrated in all subscales of CP QoL-Teen (HK) (self-report: ICC = 0.46–0.8; proxy-report: ICC = 0.40–0.72, p < 0.05). Weak to moderate association between subscales of CP QoL-Teen (HK) and CHQ (self-report: rs = 0.24–0.61; proxy-report: rs = − 0.41–0.60) was reported.Conclusion: This study showed that CP QoL-Teen (HK) has good psychometric properties. It is a valid and reliable tool to assess quality of life of adolescents with CP. What is Known:• Cerebral Palsy Quality of life-Teen (CP QoL-Teen) is a validated tool with strong psychometric properties and clinical utility in gauging the QoL in adolescents with CP during their transition from childhood to adulthood when changes in physical and emotional aspects and self-perception occur. Yet, a locally validated tool is lacking in measuring the QoL for adolescents with CP in Hong Kong.What is New:• The Chinese translated version CP QoL-Teen (HK) is a valid and reliable tool to assess quality of life of adolescents with CP tailoring to the local cultural and social background with good psychometric properties being demonstrated.

Translation and Adaptation of Cerebral Palsy Quality of Life Primary Caregiver - Teen Questionnaire in North Indian Population: CP-QOL-Teen (Hindi)

“…Lower QOL in 'access to services' and 'family health domain' could be attributed to lower socio-economic status, lack of support groups, financial instability and poor relationship with siblings. Parents tends to report lower QOL in 'feelings about functioning' as compared to teen's selfreport [3,4], which explains lower mean in this domain in our study. Gender differences can be explained by socialcultural practices and gender inequality in India.…”

“…Gender differences can be explained by socialcultural practices and gender inequality in India. The age related difference can be explained by adaptations adopted by teens and their parents with time, to cope with the disability [3,4].…”
