Health-related quality of life and its determinant factors in Thai children with cancer: parents vs. children perspectives.

BACKGROUND: Health-related quality of life (HRQOL) is a vital assessment to demonstrate the achievement in pediatric cancer care parallels that of medical treatment. The Pediatric Quality of Life Inventory (PedsQL) 3.0 Cancer Module in the Thai Version has become a standard tool to access the HRQOL among Thai children with cancer and their families. This study aimed to explore the HRQOL and factors related to HRQOL among pediatric oncology patients using the PedsQL 3.0 Cancer Module. METHODS: In 2018-2019, a single-institution, cross-sectional study was conducted among children with cancer and their families in Bangkok, Thailand. A paired-sample t-test was performed to evaluate the differences between the HRQOL scores of the child and parents' reports. Linear regression was used to evaluate factors associated with HRQOL and which particular domains of the PedsQL 3.0 Cancer Module were influenced. RESULTS: Eighty-five children with cancer and their families were enrolled. The patients' mean age was 10.82 ± 5.48 years. The most common cancer types included acute lymphoblastic leukemia (n = 32, 67%), central nervous system tumors (n = 13, 15%), osteosarcoma (n = 10, 27%) and neuroblastoma (n = 9, 24%), in rank. The mean HRQOL scores in child and parent reports were 74.37 ± 15.7 and 70.42 ± 17.15, respectively (p = 0.034). Factors negatively correlated to HRQOL in parent reports were the number of outpatient visits (p = 0.019) and hospital admissions (p = 0.002). The number of hospitalizations was the only independent factor that affected HRQOL (p = 0.044). The number of outpatient visits and/or hospital admissions was influenced by pain and hurt, nausea, procedural anxiety and communication domains (p < 0.05). Only the number of hospitalizations was an independent factor influencing the procedural anxiety domain in HRQOL (p = 0.005). CONCLUSION: HRQOL among Thai children with cancer was desirable from both children's and parent's perspectives. Differences between child and parent HRQOL scores were observed. The number of outpatient visits and hospital admissions affected HRQOL, particularly in the procedural anxiety aspect.

The Reliability of the Thai version of Health-Related Quality of Life Questionnaire: PedsQL 3.0 Cancer Module.

Assessing the health-related quality of life (HRQOL) is highly recommended as a standard of care for children with cancer in conjunction with medical treatment. The Pediatric Quality of Life Inventory (PedsQL) Cancer Module is a standard tool designed to assess the HRQOL among pediatric oncology patients. This study aimed to evaluate the reliability and correlation of the PedsQL 3.0 Cancer Module in Thai version between child and parent reports. A cross-sectional study was conducted on 85 Thai children with cancer and their families. Excellent internal consistency of the PedsQL 3.0 Cancer Module of the Thai version was addressed among child and parent reports (0.92 and 0.94, respectively). Overall positive correlations were also found between child and parent reports (r = 0.61, P < .001). However, the statistically significant differences of HRQOL scores between child and parent reports were determined on procedural anxiety (70.05 ± 26.67 vs 60.03 ± 25.6, P = .003), treatment anxiety (88.15 ± 17.37 vs 76.82 ± 26.7, P = .001), worry (66.67 ± 25.59 vs 55.34 ± 30.37, P = .003) and the total score (74.37 ± 15.7 vs 70.42 ± 17.15, P = .034). This study demonstrated desirable internal reliability with positive correlations between child and parent reports of the PedsQL 3.0 Cancer Module in Thai version, although possible differences between child and parent HRQOL scores should be considered.
