Objective measurements of ADHD symptom levels can be a highly valuable complement to ratings. However, sometimes it is not feasible to bring patients into the clinic/lab for assessment. The aim of the present study was therefore to evaluate the psychometric properties of the QbCheck, an online computerized test that measures errors and reaction time as well as activity during testing using the computer's built-in web camera. Study I (n = 27 adolescents/adults) investigated test-retest reliability and concurrent validity of the QbCheck. Study II included 142 adolescents/adults (69 with ADHD/73 controls) and investigated convergent and diagnostic validity, as well as usability, of the QbCheck. In Study I, the QbCheck showed high test-retest reliability and high concurrent validity. In Study II, high convergent validity was observed when studying associations between the QbCheck performed in the home and the QbTest performed at the clinic. In addition, the QbCheck discriminated well between patients with ADHD and controls, with a sensitivity of 82.6 and a specificity of 79.5. The QbCheck appears to be a valuable test with good psychometric properties and will thereby enable assessment of ADHD symptom levels in adolescents and adults outside the clinic in the home setting.
客观测量 ADHD 症状水平可以是一种非常有价值的补充评价方式。然而，有时让患者到诊所/实验室进行评估是不可行的。因此，本研究的目的是评估 QbCheck 的心理测量特性，QbCheck 是一种在线计算机测试，使用计算机内置的网络摄像头测量测试期间的错误、反应时间和活动。研究 I（n=27 名青少年/成年人）调查了 QbCheck 的重测信度和同时效度。研究 II 包括 142 名青少年/成年人（69 名 ADHD/73 名对照），调查了 QbCheck 的收敛和诊断有效性以及可用性。在研究 I 中，QbCheck 显示出较高的重测信度和较高的同时效度。在研究 II 中，当研究在家中进行的 QbCheck 与在诊所进行的 QbTest 之间的关联时，观察到较高的收敛效度。此外，QbCheck 能够很好地区分 ADHD 患者和对照组，其敏感性为 82.6%，特异性为 79.5%。QbCheck 似乎是一种具有良好心理测量特性的有价值的测试，从而可以在诊所外的家庭环境中评估青少年和成年人的 ADHD 症状水平。
