STUDY DESIGN
Multi-center, prospective calibration study.
OBJECTIVES
To examine the psychometric properties of item banks designed for a computer adaptive test of participation.
SETTING
Three pediatric specialty care hospitals in North America.
METHODS
Newly developed item banks containing questions about participation were administered to 381 children, 8-21 years. Unidimensionality was evaluated using categorical confirmatory factor analysis and residual correlations. Pearson's correlations were calculated between simulated CATs and the full-item banks.
RESULTS
CFI=0.905, TLI=0.951 and RMSEA=0.089 for the self-participation item bank; CFI=0.924, TLI=0.963 and RMSEA=0.083 friend-participation item bank. The 15- and 5- item simulated CATs and full-item banks were highly correlated.
CONCLUSION
The newly developed self and friend-participation item banks met the required assumptions for CAT. Simulated CATs yielded scores comparable to full-item banks. The results of the study support the use of the item banks for a CAT of participation in children following spinal cord injury.
研究设计
多中心、前瞻性校准研究。
目的
检验为参与计算机自适应测试设计的项目库的心理计量学特性。
设置
北美三家儿科专业护理医院。
方法
对 381 名 8-21 岁的儿童施测新开发的、包含参与度问题的项目库。采用分类验证性因子分析和残差相关评估单维性。计算模拟 CAT 与完整项目库之间的 Pearson 相关系数。
结果
自我参与项目库的 CFI=0.905、TLI=0.951 和 RMSEA=0.089；朋友参与项目库的 CFI=0.924、TLI=0.963 和 RMSEA=0.083。15 项和 5 项模拟 CAT 与完整项目库高度相关。
结论
新开发的自我和朋友参与项目库满足 CAT 的要求假设。模拟 CAT 产生的分数与完整项目库相当。该研究结果支持在脊髓损伤儿童的参与度 CAT 中使用项目库。
