The effect of manipulating item positioning on self-reported ADHD symptoms was examined. We assessed whether listing DSM-IV ADHD symptoms serially or interspersed affected (a) the correlation between ADHD symptoms and (b) the rate of symptom endorsement.
In Study 1, an undergraduate sample (n = 102) completed a measure that listed DSM-IV ADHD symptoms serially and a measure that interspersed DSM-IV ADHD items among non-ADHD symptoms. In Study 2, a separate undergraduate sample (n = 240) completed a measure that listed DSM-IV ADHD symptoms serially and another ADHD measure that interspersed DSM-IV ADHD items among non-DSM-IV ADHD items.
Item positioning did not affect the correlation between symptoms, but did reveal a significant bias in the rate of symptom endorsements.
These findings suggest that there is significant variability in ADHD symptom endorsements resulting from item positioning. This effect has implications for clinical assessment and epidemiological research of ADHD among college students.
研究调整项目排列方式对自我报告的注意力缺陷多动障碍（ADHD）症状的影响。我们评估了按顺序列出或穿插列出《精神疾病诊断与统计手册》第四版（DSM-IV）中ADHD症状是否会影响（a）ADHD症状之间的相关性以及（b）症状认可率。
在研究1中，一个本科样本（n = 102）完成了一份按顺序列出DSM-IV中ADHD症状的量表，以及一份将DSM-IV中的ADHD项目穿插在非ADHD症状中的量表。在研究2中，另一个本科样本（n = 240）完成了一份按顺序列出DSM-IV中ADHD症状的量表，以及另一份将DSM-IV中的ADHD项目穿插在非DSM-IV ADHD项目中的ADHD量表。
项目排列方式并未影响症状之间的相关性，但确实在症状认可率上显示出显著偏差。
这些发现表明，项目排列方式会导致ADHD症状认可率存在显著差异。这一效应对于大学生ADHD的临床评估和流行病学研究具有重要意义。
