Background and aims: Health-related quality of life (HRQOL) has garnered increasing interest especially for health care providers and researchers. The study aims to evaluate the HRQOL in parents of congenital heart disease (CHD) children, and to clarify the effect of the disease severity on the outcome of the HRQOL perception. Also, to analyze the internal consistency of the Arabic version of the World Health Organization (WHO) QOL-BREEF tool in order to determine whether the tool had good validity for the target population.
Methods: A cross-sectional study. The HRQOL perception was evaluated using WHOQOL-BREF questionnaire, and the internal consistency of the tool was tested using Cronbach's alpha (α-C), RESULTS: The study sample consisted of 200 individuals, 120 parents of CHD children, compared to 80 parents of children with minor illnesses (mean age of participating parents = 35.1 ± 9.8 years). While evaluating the HRQOL, the group of parents of children with minor illnesses had higher scores than the total group of parents of CHD children in all domains, indicating a better HRQOL. Class-IV subgroup of parents of CHD children showed the most significant lower total score of domains between all classes (44.47 ± 12, p < 0.001). With respect to the internal consistency of the WHOQOL-BREF, estimation of α-C values were 0.84 points for the group of parents of CHD children, and 0.87 for the group of parents of children with minor illnesses.
Conclusions: This short-term study emphasized that, HRQOL scores among parents of CHD children are compromised, and the severity of their children illness significantly affect the total score of domains in their HRQOL perception. Furthermore, the tool showed to be practical and efficient to evaluate the QOL of parents of CHD children in our population in future researches.
