ObjectivesTo评估的有效性和参与者的接受的在线评估的角色功能，使用计算机自适应测试（RF-CAT）。MethodsThe RF-CAT和一套既定的生活质量的工具进行了管理的横断面研究中的面板样本（n= 444）从一般人群中招募了过度选择的参与者与选定的自我报告的慢性疾病（n= 225）。的效率，得分的准确性，有效性，和可接受性的RF-CAT进行了评估，并与现有的measurements.ResultsThe RF-CAT与停止规则的6个项目的内容平衡使用25个可用的银行项目，平均在66秒内完成。RF-CAT和传统工具评分高度相关（.64-.84），并成功区分了已知组。RF-CAT比SF-36角色身体量表在更广泛的范围内进行了更精确的评估。患者的RF-CAT系统的评价是积极的整体，CAT和静态assessment.ConclusionsThe RF-CAT之间观察到的评级没有差异是可行的，更精确的静态SF-36 RP和同样可以接受的参与者作为传统的措施。在有效性的实证检验中，CAT的更好表现在统计上并不一致。需要进一步研究探索CAT评估的精度和判别力之间的关系。
ObjectivesTo evaluate the validity and participants’ acceptance of an online assessment of role function using computer adaptive test (RF-CAT).MethodsThe RF-CAT and a set of established quality of life instruments were administered in a cross-sectional study in a panel sample (n= 444) recruited from the general population with over-selection of participants with selected self-report chronic conditions (n= 225). The efficiency, score accuracy, validity, and acceptability of the RF-CAT were evaluated and compared to existing measures.ResultsThe RF-CAT with a stopping rule of six items with content balancing used 25 of the available bank items and was completed on average in 66 s. RF-CAT and the legacy tools scores were highly correlated (.64–.84) and successfully discriminated across known groups. The RF-CAT produced a more precise assessment over a wider range than the SF-36 Role Physical scale. Patients’ evaluations of the RF-CAT system were positive overall, with no differences in ratings observed between the CAT and static assessments.ConclusionsThe RF-CAT was feasible, more precise than the static SF-36 RP and equally acceptable to participants as legacy measures. In empirical tests of validity, the better performance of the CAT was not uniformly statistically significant. Further research exploring the relationship between gained precision and discriminant power of the CAT assessment is needed.
