The purpose of this study was to revise the Osteoporosis Knowledge Test (OKT) and evaluate its reliability and validity. The original OKT, developed in the early 1990 s, needed updating based on current research. A convenience sample of 105 adults completed the draft revised OKT. A subsample (n = 27) completed the questionnaire 2 weeks later to determine stability. The sample was recruited from diverse sites in western and northern Michigan over a year. The 32-item Revised OKT (2012) demonstrated internal consistency (total scale Kuder-Richardson-20 = .85, Nutrition subscale = .83, and Exercise subscale = .81). Test-retest analysis resulted in a Pearson correlation coefficient of .87. Validity was evaluated by content validity. Questions were examined for difficulty, effectiveness of distracters, and discrimination. In addition, measures of point-biserial, internal consistency and stability were determined. The Revised OKT (2012) is a comprehensive instrument reflecting current research and assesses osteoporosis knowledge of adults.
本研究的目的是修订骨质疏松症知识测试（OKT）并评估其信度和效度。最初的OKT于20世纪90年代初开发，需要根据当前研究进行更新。105名成年人的便利样本完成了修订版OKT草案。一个子样本（n = 27）在两周后完成问卷以确定稳定性。该样本是在一年时间里从密歇根州西部和北部的不同地点招募的。32项修订版OKT（2012年）显示出内部一致性（总量表库德-理查森-20系数= 0.85，营养子量表= 0.83，运动子量表= 0.81）。重测分析得出的皮尔逊相关系数为0.87。通过内容效度评估效度。检查了问题的难度、干扰项的有效性和区分度。此外，还确定了点二列相关、内部一致性和稳定性的测量值。修订版OKT（2012年）是一个反映当前研究的综合工具，用于评估成年人的骨质疏松症知识。
