This study was done to evaluate the validity and reliability of women's reproductive history questionnaire which will be used in Azar Cohort study; a cohort that is conducted by Tabriz University of Medical Science in Shabestar county for identifying risk factors of no communicable diseases. Content and face validity were evaluated by ten experts in the field and quantified as content validity index (CVI) and content validity ratio (CVR). To assess the reliability, using test-retest approach, kappa statistic was calculated for categorical variables and intra-class correlation coefficient (ICC) was used for the quantitative items. The calculated CVI and CVR were 0.91and 0.94, respectively. Reliability for all items was high. The ICC was 0.99 and kappa statistic was equal to 1. The final version of questionnaire was redesigned in 26 items with 7 subscales.
本研究旨在评估将用于阿扎尔队列研究的女性生殖史问卷的有效性和可靠性；该队列研究由大不里士医科大学在沙贝斯塔县开展，用于识别非传染性疾病的风险因素。由该领域的十位专家对内容效度和表面效度进行评估，并量化为内容效度指数（CVI）和内容效度比率（CVR）。为评估信度，采用重测法，对分类变量计算kappa统计量，对定量项目使用组内相关系数（ICC）。计算得出的CVI和CVR分别为0.91和0.94。所有项目的信度都很高。ICC为0.99，kappa统计量等于1。问卷的最终版本重新设计为包含7个分量表的26个项目。
