Participants scores on ADHD/ASD/Anxiety/Sensory processing questionnaires collected through Qualtrics

Excel file with participants total scores for subscales and total scales on ADHD/ASD/Anxiety/Sensory processing questionnaires collected through Qualtrics. A second file with the PsychoPy code and set up to run this data on is also added<b>Study Summary</b><br>This study explores the links between sensory processing difficulties and traits associated with Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD), with a particular focus on the potential mediating role of anxiety. While both conditions have been independently linked to sensory atypicalities, prior psychophysical research has predominantly centred on ASD, leaving a gap in ADHD-focused investigation.To address this, we employed a visual orientation discrimination task using a method of constant stimuli within a two-alternative forced choice paradigm. An adaptive, randomly interleaved procedure with a one-up, three-down rule was used to determine perceptual thresholds. These thresholds were analysed in relation to individual differences in ADHD, ASD, and anxiety traits through correlational analyses. A mediation model was then applied to assess whether anxiety contributes to the relationship between neurodevelopmental traits and sensory processing.Our findings show that both ADHD and ASD traits are similarly linked to altered sensory discrimination. However, trait levels of panic and generalised anxiety were specifically connected to the ADHD-Hyperactive dimension and corresponding sensory thresholds. No such anxiety-related effects were observed in association with ASD traits.These results indicate that anxiety, particularly panic and generalised forms, may serve as a key intermediary factor in the relationship between ADHD traits and sensory function, highlighting the need to consider comorbid psychological factors in sensory research on neurodevelopmental conditions.

本数据集包含通过Qualtrics平台收集的注意缺陷多动障碍（ADHD）、孤独症谱系障碍（ASD）、焦虑及感觉加工问卷的分量表与总量表得分的参与者总分数据。另有一份搭载PsychoPy代码及该实验运行配置的文件一并附加。<b>研究概述</b><br>本研究探讨感觉加工困难与注意缺陷多动障碍（ADHD）、孤独症谱系障碍（ASD）相关特质之间的关联，重点关注焦虑的潜在中介作用。尽管上述两种神经发育障碍均已被证实与感觉加工异常存在独立关联，但既往心理物理研究多聚焦于ASD，针对ADHD的相关研究尚存空白。为填补这一研究缺口，本研究采用恒定刺激法，在二择一迫选（two-alternative forced choice）范式下开展视觉方位辨别任务。实验采用自适应随机交错程序，结合“一升三降”规则以确定知觉阈值。随后通过相关分析，将知觉阈值与ADHD、ASD及焦虑特质的个体差异进行关联分析，并构建中介模型以评估焦虑是否在神经发育特质与感觉加工的关系中发挥中介作用。研究结果显示，ADHD与ASD特质均与感觉辨别能力异常存在相似关联。然而，惊恐及广泛性焦虑的特质水平仅与ADHD多动维度及对应感觉阈值存在特异性关联，未观察到此类焦虑相关效应与ASD特质相关联。上述结果表明，焦虑（尤其是惊恐与广泛性焦虑）或为ADHD特质与感觉功能之间关联的关键中介因素，这提示在神经发育障碍的感觉加工研究中，需纳入共病心理因素予以考量。
