The purpose of this study is to determine whether the Rosenbaum Concussion Knowledge and Attitudes Survey (RoCKAS) is an appropriate outcome measure to assess knowledge and attitudes toward concussion in collegiate student-athletes as determined through validity and reliability testing.
Convenience study.
The researcher recruited all athletic teams at a Division III National Collegiate Athletic Association institution.
Four hundred thirty-three collegiate student-athletes, 18 years of age or older, from a variety of sports took part in this study. As the validity of RoCKAS has never been established for the target population, this study randomly split respondents into 2 studies.
Participants in this study completed the RoCKAS during preseason meetings before concussion education. The primary researcher was not present during the completion of the survey to allow participants to answer honestly without concern of coercion.
A paper-based Rosenbaum Concussion Knowledge and Attitudes Survey.
The Concussion Knowledge Index (CKI) was distributed in 2 cluster constructs and identified variables of low and high difficulty. Multivariate statistical analysis of the Concussion Attitude Index (CAI) explains 68.79% of the total variance. The Confirmatory Factor Analysis did not confirm the hypothesis that similar constructs can be found between data sets ((Equation is included in full-text article.)= 207.902; consistent akaike information criterion = 391.550; root mean square error of approximation = 0.125, and goodness of fit index = 0.868).
The CKI is a valid and reliable measure in collegiate student-athletes. However, the results of the Confirmatory Factor Analysis indicated a poor model fit and improper correlations between attitude items. Therefore, the CAI may not be a sound outcome measure of collegiate student-athlete's attitudes toward concussions.
本研究旨在通过效度和信度测试，确定罗森鲍姆脑震荡知识与态度调查（RoCKAS）是否为评估大学生运动员对脑震荡的知识和态度的合适结果指标。
便利抽样研究。
研究人员招募了一所美国国家大学体育协会（NCAA）第三分区机构的所有运动队。
433名18岁及以上的大学生运动员参与了本研究，他们来自各种运动项目。由于RoCKAS对目标人群的效度尚未确立，本研究将受访者随机分为两项研究。
本研究的参与者在脑震荡教育前的季前会议期间完成RoCKAS。在调查完成过程中，首席研究员不在场，以便参与者能够诚实地回答，而无需担心受到胁迫。
一份纸质版的罗森鲍姆脑震荡知识与态度调查。
脑震荡知识指数（CKI）分布在两个聚类结构中，并确定了低难度和高难度变量。脑震荡态度指数（CAI）的多变量统计分析解释了总方差的68.79%。验证性因素分析未证实数据集之间存在相似结构的假设（（方程包含在全文中）=207.902；一致赤池信息准则=391.550；近似均方根误差=0.125，拟合优度指数=0.868）。
CKI是评估大学生运动员的有效且可靠的指标。然而，验证性因素分析的结果表明模型拟合不佳，态度项目之间的相关性不当。因此，CAI可能不是评估大学生运动员对脑震荡态度的可靠结果指标。
