Objective To explore the psychometric properties of the Chinese version of integrated visual and auditory continuous performance test (IVA-CPT) ,and to assess the diagnosis value of the Chinese version of IVA-CPT in two samples of children with attention deficit hyperactivity disorder (ADHD) in clinic and school.Methods 112 participants were divided into 4 groups:clinic group, clinic control group, school group and control group from school.The participants were measured by IVA-CPT and the results were compared.Results ①The integrated quotients of IVA-CPT had concordance with the dimensions of the DSM-ⅣV and ASRS.Each integrated quotients of IVA-CPT and each dimension of the DSM-ⅣV and ASRS were negatively correlated(school: r=-0.277, P＜0.05;clinic: r=-0.423, P＜0.05).The score of HI dimension was negatively correlated with integrated attention quotient and integrated inhibition quotient of IVA-CPT (r=-0.480, P＜0.01;r=-0.452, P＜0.01).② The results of the IVA-CPT and the comprehensive assessment had consistency for diagnosis of children with ADHD from the total subjects,the clinic ,and the school.And there were no difference between the sensitivity, the specificity, the coincidence rate, the missed diagnosis rate and the misdiagnosis rate of IVA-CPT when used to diagnose children with ADHD in clinic and school(x2=3.396, P＞0.05).③The IVA-CPT evaluation system had good stability according to the retest of a random sample of 25 subjects(P＜0.01).The pretest and posttest results of each full quotients of IVA-CPT were significantly correlated (P＜0.01).Conclusion The IVA-CPT not only can be used as auxiliary diagnostic tools to diagnose children with ADHD in clinic,it can be used as auxiliary diagnostic tools to diagnose children with ADHD in the community.
