背景：鉴于有许多伊朗妇女从未做过子宫颈抹片检查，本研究旨在开发和验证一种基于保护动机理论的测量工具，以评估影响伊朗妇女首次进行子宫颈抹片检查意愿的因素。材料与方法：在本心理测量学研究中，为了确定内容效度指数（CVI）和内容效度比（CVR），一个专家小组（n=10）审查了量表项目。信度通过类内相关系数（n=30）和内部一致性（n=240）来估计。此外，对从未进行过巴氏涂片检查的样本妇女（n=240）的数据进行了因素分析（探索性和一致性）。结果：编制了一份26项问卷。量表的CVI和CVR得分分别为0.89和0.90。探索性因子分析加载了一份包含感知脆弱性和严重性、恐惧、反应成本、反应效能、自我效能和保护动机（或意图）7个因素的26项问卷，共占观察方差的72.76%。验证性因子分析表明数据拟合良好。子量表的内部一致性（范围0.70-0.93）和重测信度（范围0.72-0.96）可接受。结论：本研究表明，设计的仪器是一种有效和可靠的工具，用于测量影响妇女进行第一次巴氏涂片检查意愿的因素。
Background: Given that there are many Iranian women who have never had a Pap smear, this study was designed to develop and validate a measurement tool based on the Protection Motivation Theory to assess factors influencing the Iranian women's intention to perform first Pap testing. Materials and Methods: In this psychometric research, to determine the Content Validity Index (CVI) and the Content Validity Ratio (CVR), a panel of experts (n=10) reviewed scale items. Reliability was estimated through the Intraclass Correlation Coefficient (n=30) and internal consistency (n=240). Also, factor analysis (exploratory and conformity) was performed on the data of the sample women who had never had a Pap smear test (n=240). Results: A 26-item questionnaire was developed. The CVI and CVR scores of the scale were 0.89 and 0.90, respectively. Exploratory factor analysis loaded a 26-item with seven factors questionnaire (perceived vulnerability and severity, fear, response costs, response efficacy, self-efficacy, and protection motivation (or intention)) that jointly accounted for 72.76% of the observed variance. Confirmatory factor analysis indicated a good fit for the data. Internal consistency (range 0.70-0.93) and test-retest reliability (range 0.72-0.96) of sub-scales were acceptable. Conclusions: This study showed that the designed instrument was a valid and reliable tool for measuring the factors influencing the women's intention to perform their first Pap testing.
