To present and validate psychometric properties of Urdu version CLDQ, yet another objective was to do exploratory factorial analysis (EFA) of CLDQ Urdu version.
This Cross-sectional Analytical Study was conducted at Dr. Ruth K.M. Pfau Civil Hospital Karachi during the period Nov. 15, 2021 to Jan. 30, 2022. CLDQ Urdu questionnaire was self-administered by the patients. The questionnaire consisted of 29 items and responses were recorded on 7-point Likert type scale. Reliability testing was done by Cronbach's α, 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.
A total of 320 patients were selected after informed consent. All conditions for adequate EFA were met (Cronbach's α =.949; KMO = .846; BTS ≤.001). Mean CLDQ Urdu score was 156.74 in male and 133.27 in female (<.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. EFA resulted in reduction of domains to 4 (Muscular Symptoms, Emotional Symptoms, Abdominal Symptoms & Somnolence) & reduced the number of items from 29 to 11.
Urdu CLDQ version is validated in our settings. EFA resulted in reductions in number of domains and items. CLDQ Urdu showed that quality of life decreases significantly with Child Class.
呈现并验证乌尔都语版CLDQ的心理测量特性，另一个目的是对乌尔都语版CLDQ进行探索性因子分析（EFA）。
这项横断面分析研究于2021年11月15日至2022年1月30日在卡拉奇鲁思·K.M. 普法乌博士市民医院进行。乌尔都语版CLDQ问卷由患者自行填写。该问卷包含29个项目，回答采用7点李克特量表记录。通过克朗巴哈α系数进行信度测试，测试值>0.7被视为可靠。采用主成分分析法和方差最大化旋转进行探索性因子分析（EFA）。进行EFA的充分性取决于凯泽 - 迈耶 - 奥尔金（KMO）值≥0.5以及巴特利特球形检验（BTS）≤0.05。还使用方差分析比较了乌尔都语版CLDQ的平均得分与儿童类别，并进行了事后分析。
在获得知情同意后，共选取了320名患者。满足了进行充分EFA的所有条件（克朗巴哈α系数 = 0.949；KMO = 0.846；BTS≤0.001）。男性乌尔都语版CLDQ平均得分为156.74，女性为133.27（P<0.001）。儿童A类的生活质量最佳得分为186.63±6.91，儿童C类最差得分为109.78±21.33。EFA将领域减少到4个（肌肉症状、情绪症状、腹部症状和嗜睡）并将项目数量从29个减少到11个。
乌尔都语版CLDQ在我们的研究环境中得到了验证。EFA减少了领域和项目的数量。乌尔都语版CLDQ表明，生活质量随儿童类别显著下降。
