The aim of the present study was to perform reliability and validity analyses of the Turkish version of the Clinical Opiate Withdrawal Scale which is used to determine the severity of opiate withdrawal.
Initially, the Clinical Opiate Withdrawal Scale (COWS) was translated into Turkish and subsequently back-translated into English. The originality of the back-translated version was approved by the author who developed the scale. After the translation was completed, the scale was used to assess the withdrawal symptoms of 100 patients with opiate withdrawal and 41 patients with alcohol withdrawal. Cronbach's alpha was used in the reliability assessment; explanatory and confirmatory factor analyses were used in structural validity assessment; and in scale validity, ROC analysis was used among diagnosis groups.
The Cronbach's alpha internal consistency coefficient was calculated as 0.74 in reliability analyses. The correlation coefficient was found to be 0.975 (p<0.001) for inter-rater reliability. Factor analysis was conducted for the structural validity of the scale and findings that support the unidimensional structure of the scale were observed. In the confirmatory factor analysis, CFI, GFI and RMSEA values were found to be 0.905, 0.905 and 0.079, respectively. It was detected that COWS was successful in distinguishing between opiate and alcohol withdrawal symptoms and the area under the ROC curve was 0.878.
This study showed that the Turkish version of COWS can be used reliably and validly for assessing opiate withdrawal.
本研究旨在对用于确定阿片类药物戒断严重程度的《临床阿片类药物戒断量表》土耳其语版本进行信度和效度分析。
首先，将《临床阿片类药物戒断量表》（COWS）翻译成土耳其语，随后再回译为英语。回译版本的原创性得到了该量表开发者的认可。翻译完成后，该量表用于评估100例阿片类药物戒断患者和41例酒精戒断患者的戒断症状。信度评估采用Cronbach's alpha；结构效度评估采用解释性和验证性因素分析；在量表效度方面，诊断组之间采用ROC分析。
信度分析中，Cronbach's alpha内部一致性系数计算为0.74。评分者间信度的相关系数为0.975（p<0.001）。对该量表进行结构效度的因素分析，观察到支持该量表单维结构的结果。在验证性因素分析中，CFI、GFI和RMSEA值分别为0.905、0.905和0.079。检测发现COWS能够成功区分阿片类药物和酒精戒断症状，ROC曲线下面积为0.878。
本研究表明，COWS土耳其语版本可可靠且有效地用于评估阿片类药物戒断。
