虽然自我效能（SE），社会认知理论的一个结构，已被证明会影响其他筛查行为，目前很少有措施存在测量巴氏试验SE。本文介绍了这种措施的发展和心理测试墨西哥裔美国妇女。本研究使用了两个单独的50岁或以上墨西哥裔美国妇女样本的数据，这些样本是作为开发和评估乳腺癌和宫颈癌筛查教育计划研究的一部分获得的。探索性因素分析表明，一个单因素的解决方案和所有的项目负载> .73。验证性分析证实了一个单因素结构，所有标准化负荷大于0.40的假设。8项SE量表表现出较高的内部一致性（Cronbach α = .95）。正如假设的那样，SE与知识、既往经验和筛查意图相关。逻辑回归支持了理论关系，即SE较高的女性更有可能最近进行了巴氏试验。结果显示，干预后SE显著增加，表明该措施对随时间变化具有良好的敏感性。
While self-efficacy (SE), a construct from Social Cognitive Theory, has been shown to influence other screening behaviors, few measures currently exist for measuring Pap test SE. This paper describes the development and psychometric testing of such a measure for Mexican-American women. Data from two separate samples of Mexican-American women 50 years or older, obtained as part of a study to develop and evaluate a breast and cervical cancer screening educational program, were used in the current study. Exploratory factor analysis indicated a single factor solution and all item loadings were > .73. Confirmatory analysis confirmed a single factor structure with all standardized loadings greater than .40 as hypothesized. The eight item SE scale demonstrated high internal consistency (Cronbach's alpha = .95). As hypothesized, SE was correlated with knowledge, prior experience, and screening intention. Logistic regression supported the theoretical relationship that women with higher SE were more likely to have had a recent Pap test. Findings showed a significant increase in SE following the intervention, indicating the measure has good sensitivity to change over time.
