Mounting evidence suggests that obsessive intrusions are often accompanied and amplified by perceptual experiences of different modalities (e.g., feeling dirt on one's skin while experiencing intrusive thoughts about contamination). Pilot studies conducted online with individuals endorsing mild obsessive-compulsive symptoms have linked the co-occurrence of perceptual experiences and obsessions to the severity of subsequent compulsive behaviour as well as low insight. However, it is presently unclear whether sensory experiences accompany all types of obsessional thoughts or are restricted to certain preoccupations (e.g., contamination and aggression). The present study examined a clinical inpatient and outpatient sample with a formally diagnosed obsessive-compulsive disorder (N = 34). Perceptual properties of intrusive thoughts were assessed with the Sensory Properties of Obsessions Questionnaire. The prevalence of perception-laden obsessive thoughts was comparable with prior studies (73.5%), but the intensity was significantly greater. No association was observed between perceptual experiences and expert-rated insight. However, the severity of perception-laden obsessions predicted the frequency of and impairment associated with compulsive behaviour. This was particularly strong for obsessions about contamination. The present study confirms the high prevalence and clinical relevance of perceptual experiences that accompany obsessions and further challenges the traditional trichotomy splitting mental phenomena into thoughts, intrusions, and hallucinations.
越来越多的证据表明，强迫观念常常伴随着不同感觉模式的知觉体验（例如，在出现有关污染的侵入性思维时，感觉皮肤上有污垢）。在线对轻度强迫症症状个体进行的初步研究将知觉体验和强迫观念的同时出现与随后强迫行为的严重程度以及洞察力降低联系起来。然而，目前尚不清楚感觉体验是否伴随着所有类型的强迫性思维，还是仅限于某些困扰（例如，污染和攻击）。本研究对具有正式诊断的强迫症的住院和门诊临床样本（N=34）进行了检查。使用强迫观念的感觉特性问卷评估侵入性思维的感觉特性。有知觉的强迫性思维的患病率与先前的研究相当（73.5%），但强度明显更高。知觉体验与专家评定的洞察力之间没有关联。然而，有知觉的强迫观念的严重程度预测了强迫行为的频率和相关障碍。这在关于污染的强迫观念中尤为强烈。本研究证实了伴随强迫观念的知觉体验的高患病率和临床相关性，并进一步挑战了将心理现象传统上分为思维、侵入和幻觉的三分法。
