The questionnaire consisted of 29 items and responses were recorded on 7-point Likert type scale. Reliability testing was done by Cronbach’s a, test value of >0.7 is taken as reliable. Exploratory factor analysis (EFA) was conducted with principal component analysis with varimax rotation. Adequacies for conduction of EFA depended on Kaiser-Meyer-Olkin (KMO) value of =0.5 and Bartlett’s Test of Sphericity (BTS) of =0.05. Mean CLDQ Urdu scores were also compared with Child Class using ANOVA and post-hoc analysis was done.Results: A total of 320 patients were selected after informed consent. All conditions for adequate EFA were met (Cronbach’s a =.949; KMO = .846; BTS =.001). Mean CLDQ Urdu score was 156.74 in male and 133.27 in female (p<.001). Child Class-A had best quality of life with score of 186.63 ±6.91 and Child Class-C had the worst with scores of 109.78 ±21.33.
