*P <0.001 compared to total group of parents of CHD children {Unpaired T-test with Welch’s correction test was used for comparison between total group of parents of CHD children and control (group of parents of children with minor illnesses)}

^#P < 0.05, ### P <0.001 compared to total score of domains of Class I subgroup {One-way ANOVA followed by Tukey Multiple Comparison Test as post hoc test was used for comparison between total score of domains of class I subgroup and other subgroups of parents of CHD children (class II, III, IV)}
