The reliability of a measuring instrument is a major criterion for assessing its quality and adequacy. This article describes reliability pilot testing done with the Ohio AIDS Prevention Survey (Fellner & Thomas, 1989-90) in a sample of sexually active women of childbearing age. Previous alpha reliabilities of the knowledge scale of the survey have ranged from .71-.81, while the reliabilities of the attitudes and beliefs scale have ranged from .33-.45. In this sample, reliability measures for the knowledge and attitudes and beliefs scales were .65 and .45, respectively. The results of this study indicate that the Ohio AIDS Prevention Survey is clearly in its developmental stages and that further development of the survey is necessary prior to continued use in public health settings.
测量仪器的可靠性是评估其质量和适用性的主要标准。本文描述了对俄亥俄州艾滋病预防调查（费尔纳和托马斯，1989 - 1990年）在育龄性活跃女性样本中进行的可靠性预测试。该调查知识量表先前的阿尔法信度在0.71至0.81之间，而态度和信念量表的信度在0.33至0.45之间。在这个样本中，知识量表以及态度和信念量表的可靠性测量值分别为0.65和0.45。本研究结果表明，俄亥俄州艾滋病预防调查显然仍处于发展阶段，在继续用于公共卫生环境之前，有必要对该调查进行进一步完善。
