本文描述了冰岛改编的成人阅读历史问卷(ARHQ)的心理测量测试，该问卷旨在检测表明阅读困难的阅读困难史。在2187名成年人的大样本和多样化样本中进行测试，冰岛适应显示出内部一致性可靠性(Cronbach‘s Alpha=.92)和重测可靠性(r=.93)。效度是通过比较儿童时期接受ICD-10诊断为特定阅读障碍的成年人(F81.0；n=419)和被定义为非阅读障碍的成年人(n=679)的分数来建立的。ROC曲线分析的曲线下面积为.92(95%CI=.90，.93，p<；.001)，临界值为.43，灵敏度为84.5%，特异度为83.7%。探索性因素分析(n=2,187)表明，阅读障碍症状、当前阅读和记忆三个子量表的平均分在被诊断的阅读障碍患者、阅读障碍亲属和人群对照组之间存在显著差异。我们的结果支持ARHQ在冰岛语中作为冰岛成人阅读障碍的自我报告筛查工具的适用性。
This article describes psychometric testing of an Icelandic adaptation of the Adult Reading History Questionnaire (ARHQ), designed to detect a history of reading difficulties indicative of dyslexia. Tested in a large and diverse sample of 2,187 adults, the Icelandic adaptation demonstrated internal consistency reliability (Cronbach's alpha = .92) and test-retest reliability (r = .93). Validity was established by comparing scores of adults who as children received ICD-10 diagnoses of specific reading disorder (F81.0; n = 419) to those of adults defined as nondyslexics (n = 679). ROC curve analysis resulted in an area under the curve of .92 (95% CI = .90, .93, p < .001) and a cutoff score of .43 with sensitivity of 84.5% and specificity of 83.7%. An exploratory factor analysis (n = 2,187) suggested three subscales, Dyslexia Symptoms, Current Reading, and Memory, the mean scores of which differed significantly among diagnosed dyslexics, relatives of dyslexics, and population controls. Our results support the applicability of the ARHQ in Icelandic as a self-report screening tool for adult dyslexia in Iceland.
