Insights
The Chinese version of the Pediatric Quality of Life Inventory (PedsQL) is a valid and reliable tool for assessing children's health-related quality of life. This validated PedsQL scale is suitable for Chinese pediatric research and clinical use.
Area of Science:
- Pediatric Health
- Quality of Life Assessment
- Psychometrics
Background:
- The Pediatric Quality of Life Inventory (PedsQL) is a widely used measure for children's health-related quality of life.
- Validating translated instruments is crucial for cross-cultural research and clinical application.
Purpose of the Study:
- To translate and examine the validity and reliability of the PedsQL for children aged 2-4 and 5-7 years in a Chinese population.
- To assess the psychometric properties of the Chinese PedsQL versions.
Main Methods:
- Translation of PedsQL reports for two age groups (2-4 and 5-7 years) into Chinese.
- Assessment of content validity, test-retest reliability, internal consistency, and construct validity.
- Involved 186 children and parents; examined parent-child report correlation.
Main Results:
- Generally good internal consistency and moderate to good test-retest reliability were found.
- Significant differences were observed between disabled and non-disabled children across most subscales.
- Moderate to high correlation between parent and child reports for the 5-7 year age group.
Conclusions:
- The translated Chinese PedsQL for young children (2-7 years) demonstrates good reliability and validity.
- The Chinese PedsQL is suitable for measuring health-related quality of life in Chinese pediatric research and clinical settings.
Abstract:
The Pediatric Quality of Life Inventory (PedsQL) is a scale for assessing health-related quality of life of children and adolescents aged 2--18 years. Three reports of PedsQL for the age ranges 2--4 years and 5--7 years were translated into Chinese and their validities were examined. A total of 186 children and parents were involved in the study. Content validity, test-retest reliability, internal consistency reliability and construct validity were assessed. The correlation of parents' and children's reports was also examined. The results showed that the internal consistency is generally good, test-retest reliability ranged from moderate to good, differences between disabled and non-disabled individuals are significant in total scores and in all subscales except for the physical functioning subscale for the children's self-report for the age ranges of 2-4 years and 5-7 years and the correlation between the reports of the parents and children for the age range of 5-7 years is moderate to high. This suggests that the newly translated Chinese PedsQL for children aged 2-4 years and 5-7 years seems to be reliable and valid to be used as a measure of health-related quality of life in Chinese pediatric research and clinical applications.
