Abstract：
UNASSIGNED: Overactive bladder (OAB) is characterized by urinary frequency and is recognized as a disorder. Various tools are available for diagnosing this condition. This study aimed to evaluate the reliability and validity of the Persian version of the 8-item Overactive Bladder Scale (OAB-V8).
UNASSIGNED: This analytical cross-sectional study was conducted on a sample of 150 OAB patients. The OAB-V8 scale was translated and culturally adapted following established guidelines. Face and content validity were assessed using the Impact Score (IS), Content Validity Index (CVI), and Content Validity Ratio (CVR) indices. Reliability was evaluated by calculating Cronbach\'s alpha (α) and utilizing the test-retest method (Intra-class correlation coefficients (ICC)). Construct validity was explored through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). All statistical analyses were carried out using SPSS version 24 and AMOS version 24, with a significance level set at 5 %.
UNASSIGNED: The face validity was confirmed, with all items having an IS value greater than 1.5. Content validity was also confirmed, as most items had a Content Validity Index (CVI) higher than 0.79, and the average Content Validity Ratio (CVR) value was 0.96. In the initial phase of Exploratory Factor Analysis (EFA), the sample adequacy and suitability of the exploratory analysis were confirmed (Kaiser-Meyer-Olkin (KMO) test value = 0.784, Bartlett\'s Test p-value <0.05). Two dimensions explaining 61.87 % of the variance were then extracted. In the Confirmatory Factor Analysis (CFA), the fit indices were deemed acceptable (χ^2/df = 2.006, CFI = 0.96, GFI = 0.95, AGFI = 0.89, TLI = 0.93, RMSEA = 0.08). The reliability was confirmed with an alpha coefficient of 0.81 and an Intraclass Correlation Coefficient (ICC) of 0.98.
UNASSIGNED: The Persian version of the OAB-V8 questionnaire demonstrated good validity and reliability, indicating its suitability for use in Persian-speaking countries.

摘要：
■膀胱过度活动症（OAB）的特征是尿频，被认为是一种疾病。各种工具可用于诊断这种情况。本研究旨在评估波斯语版本的8项膀胱过度活动量表（OAB-V8）的信度和效度。
■这项分析性横断面研究是对150名OAB患者的样本进行的。OAB-V8量表按照既定准则进行了翻译和文化调整。使用影响评分(IS)评估面部和内容的有效性，内容有效性指数（CVI），和内容效价比(CVR)指数。通过计算Cronbach'sα（α）并使用测试重测方法（类内相关系数（ICC））来评估可靠性。通过探索性因子分析(EFA)和验证性因子分析(CFA)探讨结构效度。使用SPSS版本24和AMOS版本24进行所有统计分析,显著性水平设定为5%。
■确认了面部有效性，所有项目的IS值大于1.5。内容的有效性也得到了证实，因为大多数项目的内容有效性指数（CVI）高于0.79，平均内容有效性比（CVR）值为0.96。在探索性因素分析(EFA)的初始阶段，探索性分析的样本充分性和适用性得到证实(Kaiser-Meyer-Olkin(KMO)检验值=0.784,Bartlett检验p值<0.05).然后提取解释61.87%方差的两个维度。在验证性因子分析(CFA)中，拟合指数被认为是可以接受的(χ^2/df=2.006，CFI=0.96，GFI=0.95，AGFI=0.89，TLI=0.93，RMSEA=0.08)。用0.81的α系数和0.98的组内相关系数(ICC)证实了可靠性。
■波斯语版本的OAB-V8问卷表现出良好的有效性和可靠性，表明它适合在波斯语国家使用。
