Reliability and validity of the Thai version of the Pediatric Quality of Life Inventory 4.0.
ABSTRACT PURPOSE: The study aimed to evaluate the reliability and validity of the Thai version of the Pediatric Quality of Life Inventory™ 4.0 Core Scales (PedsQL) as a measure of health-related quality of life (HRQOL). METHODS: The PedsQL items were completed by 2,086 pupils aged 8-15 years and 1,914 parents from four schools, and 100 pediatric outpatients and 100 parents from a University Hospital. Test-retest reliability was conducted in a randomly selected of 150 pupils at a 1-month interval. RESULTS: Internal consistency reliability for the Total Scale score (α = 0.84 self-report, 0.88 proxy-report), Physical Health Summary score (α = 0.76 self-report, 0.79 proxy-report), and Psychosocial Health Summary score (α = 0.74 self-report, 0.85 proxy-report) exceeded the minimum reliability standard of 0.70. School children had significantly higher mean HRQOL scores compared to those with chronic health conditions for all subscales with the mean differences of 3.1-12.4 for self-report (p < 0.03) and 7.7-15.6 for proxy-report (p < 0.001). Test-retest reliability showed intraclass correlation coefficients above 0.60 in all subscales (p < 0.001). CONCLUSIONS: The Thai version of PedsQL had adequate reliability and validity and could be used as an outcome measure of HRQOL in Thai children aged 8-15 years.

ABSTRACT: This study investigates psychosocial outcome and quality-of-life in children who have experienced arterial ischaemic stroke (AIS), using a multidimensional and multi-perspective approach. It also examines the predictors of quality-of-life following childhood AIS. Forty-nine children between 6-18 years of age were recruited from a specialist childhood stroke clinic. Children, their parents and their teachers rated the child's quality-of-life. Questionnaires rating the child's self-esteem, behaviour and emotions were administered. Each child also underwent a neuropsychological assessment. The findings show that child-, parent- and teacher-rated health-related quality-of-life (HRQoL) is significantly lower than comparative norms following childhood AIS, across all domains (physical, emotional, social, school and cognitive functioning). Predictors of HRQoL include neurological severity, executive function, self-esteem and family functioning. Improved screening, services and interventions are necessary to monitor longer-term outcome and provide support for children who have experienced AIS and their families.Brain Injury 05/2012; 26(9):1072-83.

ABSTRACT: Background: Ensuring a good life for all parts of the population, including children, is high on the public health agenda in most countries around the world. Information about children's perception of their health-related quality of life (HRQoL) and its socio-demographic distribution is, however, limited and almost exclusively reliant on data from Western higher income countries. Objectives: To investigate HRQoL in schoolchildren in Tonga, a lower income South Pacific Island country, and to compare this to HRQoL of children in other countries, including Tongan children living in New Zealand, a high-income country in the same region. Design: A cross-sectional study from Tonga addressing all secondary schoolchildren (11-18 years old) on the outer island of Vava'u and in three districts of the main island of Tongatapu (2,164 participants). A comparison group drawn from the literature comprised children in 18 higher income and one lower income country (Fiji). A specific New Zealand comparison group involved all children of Tongan descendent at six South Auckland secondary schools (830 participants). HRQoL was assessed by the self-report Pediatric Quality of Life Inventory 4.0. Results: HRQoL in Tonga was overall similar in girls and boys, but somewhat lower in children below 15 years of age. The children in Tonga experienced lower HRQoL than the children in all of the 19 comparison countries, with a large difference between children in Tonga and the higher income countries (Cohen's d 1.0) and a small difference between Tonga and the lower income country Fiji (Cohen's d 0.3). The children in Tonga also experienced lower HRQoL than Tongan children living in New Zealand (Cohen's d 0.6). Conclusion: The results reveal worrisome low HRQoL in children in Tonga and point towards a potential general pattern of low HRQoL in children living in lower income countries, or, alternatively, in the South Pacific Island countries.Global Health Action 08/2014; 7:24896.
