Reliably diagnosing autism spectrum disorders (ASD) in adulthood poses a challenge to clinicians due to the absence of specific diagnostic markers. This study investigated the potential of interpersonal synchrony (IPS), which has been found to be reduced in ASD, to augment the diagnostic process. IPS was objectively assessed in videos of diagnostic interviews in a representative referral population from two specialized autism outpatient clinics. In contrast to the current screening tools that could not reliably differentiate, we found a significant reduction of IPS in interactions with individuals later diagnosed with ASD (n = 16) as opposed to those not receiving a diagnosis (n = 23). While these findings need to be validated in larger samples, they nevertheless underline the potential of digitally-enhanced diagnostic processes for ASD.

由于缺乏特定的诊断标志物，在成年期可靠地诊断自闭症谱系障碍 (ASD) 对临床医生构成挑战。这项研究调查了人际同步 (IPS) 的潜力，已被发现在 ASD 中减少，以增强诊断过程。在来自两个专业自闭症门诊的代表性转诊人群的诊断访谈视频中客观地评估了 IPS。与目前无法可靠区分的筛查工具相比，我们发现与后来被诊断为 ASD 的个体 (n = 16) 的互动中 IPS 显着减少，而不是那些未接受诊断的个体 (n = 23)。虽然这些发现需要在更大的样本中进行验证，但它们仍然强调了 ASD 数字增强诊断过程的潜力。
