强迫症量表修订版（OCI-R）分量表的心理测量学特性尚未在诊断为强迫症（OCD）的个体的临床样本中得到验证。采用OCI-R和Yale-Brown强迫量表（Y-BOCS）对186例强迫症患者和17例广泛性焦虑症（GAD）患者进行调查。验证性因素分析揭示了一个可接受的因素结构。与其他OCD患者和GAD患者相比，具有给定主要症状亚型的患者在OCI-R的相应子量表上升高。此外，在Y-BOCS上承认存在症状亚型但不是原发性的患者，与不认可该症状亚型的患者和GAD患者相比，在该量表上的OCI-R评分升高。结果表明，OCI-R的分量表是有效的测量强迫症的六个症状亚型。OCI-R是一种心理测量学上的声音，简短的工具。目前的数据结合以前的努力表明，它适用于临床和非临床人群，并用于临床和研究目的。进一步的研究应该检查特定分量表对治疗效果的敏感性，以及增加更多项目以解释强迫症其他症状领域的可能性。(c)2006爱思唯尔有限公司保留所有权利。
The psychometric properties of the Obsessive-Compulsive Inventory-Revised (OCI-R) subscales have not been validated in a clinical sample of individuals diagnosed with obsessive-compulsive disorder (OCD). Data were collected on 186 patients diagnosed with OCD and 17 patients diagnosed with generalized anxiety disorder (GAD) using the OCI-R and the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Confirmatory factor analysis revealed an acceptable factor structure. Patients with a given primary symptom subtype were elevated on the corresponding subscale of the OCI-R compared to other OCD patients and patients with GAD. In addition, patients who acknowledged that symptom subtype as present but not primary on the Y-BOCS had elevated OCI-R scores on that scale compared to patients who did not endorse that symptom subtype and patients with GAD. Results indicate that the subscales of the OCI-R are valid measures of six symptom subtypes of OCD. The OCI-R is a psychometrically sound, brief instrument. The current data combined with previous efforts suggest that it is appropriate for clinical and non-clinical populations, and for clinical and research purposes. Further research should examine the sensitivity of the specific subscales to treatment effects, and the potential for adding more items to account for other symptom domains of OCD.
