Abstract

OBJECTIVE

To evaluate the test-retest reliability and construct validity of the concussion knowledge assessment tool (CKAT) as a measure of knowledge of concussion and its management among chiropractic subgroups and to compare these properties for two scoring strategies for the CKAT.

METHODS

Three chiropractic subgroups (first year students, interns and sports chiropractors) completed the CKAT via SurveyMonkey with as second administration two to six weeks later for a subset of respondents. Scatter plots and Intraclass Correlation Coefficients (ICC) were used for test-retest reliability. A priori hypotheses regarding the relationship of CKAT scores across known subgroups, and with concussion knowledge self-rankings were established prior to data collection. Distributions of CKAT scores were compared across the subgroups using boxplots and ANOVA for known groups validity, and correlation of CKAT scores with concussion knowledge self-ranking was examined.

RESULTS

Test-retest ICC for the revised scoring was 0.68 (95%CI 0.51-0.80). First year students had a mean revised CKAT (out of 49) of 36.9 (SD= 4.7), interns 39.9 (SD=3.0) and sports chiropractors 41.8 (SD=3.2) which are significantly different (F=17.54; p<0.0001).

CONCLUSIONS

The CKAT distinguished between chiropractic subgroups expected to have different levels of knowledge, supporting construct validity, however, it did not achieve adequate test-retest reliability.

摘要

目的

评估脑震荡知识评估工具（CKAT）作为一种衡量整脊亚组中脑震荡知识及其管理的工具的重测信度和结构效度，并比较CKAT两种评分策略的这些特性。

方法

三个整脊亚组（一年级学生、实习生和运动整脊师）通过SurveyMonkey完成了CKAT测试，部分受访者在两到六周后进行了第二次测试。使用散点图和组内相关系数（ICC）来评估重测信度。在数据收集之前，就已知亚组间CKAT分数的关系以及与脑震荡知识自我排名的关系建立了先验假设。使用箱线图和方差分析比较亚组间CKAT分数的分布以评估已知组效度，并检验CKAT分数与脑震荡知识自我排名的相关性。

结果

修订评分的重测ICC为0.68（95%CI 0.51 - 0.80）。一年级学生修订后的CKAT平均得分（满分49分）为36.9（标准差 = 4.7），实习生为39.9（标准差 = 3.0），运动整脊师为41.8（标准差 = 3.2），这些得分存在显著差异（F = 17.54；p < 0.0001）。
