The aim of this study is to translate into the Turkish language, and test the reliability and validity, of the Turkish version of the Constipation Risk Assessment Scale (CRAS). This study consisted of 245 adult in-patients who were hospitalized in the medical and surgical clinics of Celal Bayar University Hospital in January through May 2007. The patients were categorized into two groups (constipated and not constipated) according to Rome II criteria. All participants were assessed with the CRAS. The CRAS was retested on 32 patients selected randomly from among the initial constipated group (n =152). The statistical analysis consisted of reliability and validity analyses. Test-retest comparison and internal consistency were used to assess the reliability of the instrument. Divergence and known groups approaches were used to test for construct validity. Correlation analysis using the Pearson's coefficient was conducted to assess the test-retest. For testing of the criteria and known groups, Student's t test and Mann-Whitney U test were used. Cronbach's = value for the constipated respondents was r = 61.9. According to the effect size comparisons, the most effective variable on the CRAS score was perception of constipation risk requirement. The overall score and subsection score correlations were also found acceptable (r = 0.47-0.57).
本研究旨在将便秘风险评估量表（CRAS）的土耳其语版本进行翻译，并测试其信度和效度。本研究纳入了245名成年住院患者，这些患者于2007年1月至5月在切拉尔·拜亚尔大学医院的内科和外科病房住院。根据罗马II标准，将患者分为两组（便秘组和非便秘组）。所有参与者均接受CRAS评估。对最初便秘组（n = 152）中随机选取的32名患者进行了CRAS复测。统计分析包括信度和效度分析。采用重测比较和内部一致性来评估该工具的信度。采用发散法和已知组法来检验结构效度。使用Pearson系数进行相关分析以评估重测情况。对于标准和已知组的检验，使用了Student's t检验和Mann-Whitney U检验。便秘受访者的Cronbach's =值为r = 61.9。根据效应量比较，对CRAS评分影响最大的变量是对便秘风险需求的感知。总体评分与各部分评分之间的相关性也被认为是可接受的（r = 0.47 - 0.57）。
