ABSTRACT
Objective: To determine the validity and reliability of the Chinese parent proxy and child self-report health related quality of life measure for children with epilepsy (CHEQOL-25) in Malaysia. Methods: Face and content validity of the Chinese parent proxy and child self-report CHEQOL-25 was verified by an expert panel, and piloted in five children with epilepsy (CWE). The Chinese CHEQOL-25 was then administered to 40 parent proxies and their CWE (aged 8-18 years), from two tertiary hospitals, at baseline and 2 weeks later. Results: Forty parents and their CWE were recruited. Cronbach’s alpha for each subscale ranged from 0.56-0.83. At test-retest, the interclass correlation for all items ranged from 0.68-0.97. Items 8 and 25 were removed as their corrected item-total correlation values were <0.3. Epilepsy severity, the number of anti-epileptic drugs taken daily, number of close friends and number of time spent with friends were found to be associated with the parent proxy CHEQOL-25 score. Duration of epilepsy, child’s cognitive ability, number of close friends and number of time spent with friends were associated with child self-report CHEQOL-25. The parent proxy and the child selfreport showed high to fair agreement on the “interpersonal/social” [Intraclass correlation coefficient (ICC)=0.670, p<0.001] and “epilepsy secrecy” subscale (ICC=0.417, p=0.048). Conclusions: Our small study found that the Chinese CHEQOL-25 was a valid and reliable questionnaire to assess the quality of life of children with epilepsy from the parent prospective and child self-report when items 8 and 25 were removed.

PURPOSE: We aimed to cross-culturally adapt the parent-proxy Health-Related Quality of Life Measure for Children with Epilepsy (CHEQOL-25) into Malay and to determine its validity and reliability among parents of children with epilepsy in Malaysia. METHODS: The English version of the parent-proxy CHEQOL-25 was translated according to international guidelines to Malay. Content validity was verified by an expert panel and piloted in five parents of children with epilepsy (CWE). The Malay parent-proxy CHEQOL-25 was then administered to 40 parents of CWE, aged 8-18years from two tertiary hospitals, at baseline and 2weeks later. Parents were also required to complete the Malay PedsQL™ 4.0 so that convergent validity could be assessed. Hypothesis testing was assessed by correlating the individual subscales in the parent-proxy CHEQOL-25 with epilepsy severity, the number of anticonvulsants, and the number of close friends. RESULTS: Participants from the pilot study did not encounter any problems in answering the final translated Malay parent-proxy CHEQOL-25. Hence, no further modifications were made. Cronbach's α for each subscale of the Malay parent-proxy CHEQOL-25 ranged from 0.67 to 0.83. The intraclass correlation coefficient for all items at test-retest ranged from 0.70 to 0.94. Both the CHEQOL-25 and the PedsQL™ 4.0 showed good correlation in the social and emotional subscales (r=0.598, p=0.002 and r=0.342, p=0.031, respectively). The severity of epilepsy, higher number of antiepileptic drug(s), poorer cognitive ability of the child, lower number of close friends, and lesser amount of time spent with friends were significantly associated with poorer health-related quality of life. CONCLUSIONS: The Malay parent-proxy CHEQOL-25 was found to be a valid and reliable instrument to assess parents' perceived HRQOL of their CWE in Malaysia.
