Accurately and reliably measuring the presence and severity of Obsessive-Compulsive Disorder (OCD) symptoms is essential for both routine clinical work and research. The current study investigated psychometric properties of the dimensional obsessive-compulsive scale-short form (DOCS-SF). DOCS-SF was developed and validated in Norwegian. DOCS-SF contains a checklist with four symptom categories and five severity items scored on a zero to eight scale yielding a total score of 0-40. Data were collected from adults with a current diagnosis of OCD ( = 204) and a community comparison group ( = 211). The results provided evidence of internal consistency and convergent validity, although evidence for discriminant validity was mixed. Evidence was also found for diagnostic sensitivity and specificity, and treatment sensitivity. The analyses suggested a cut-off score of 16. In summary, the data obtained proved similar to studies published on the original dimensional obsessive-compulsive scale. There is strong evidence for the reliability and validity of the DOCS-SF for assessing OCD symptoms in individuals with this condition and in non-clinical individuals.
准确可靠地测量强迫症（OCD）症状的存在与否及其严重程度，对于日常临床工作和研究都至关重要。本研究调查了维度强迫症量表简版（DOCS-SF）的心理测量特性。DOCS-SF是在挪威开发并验证的。DOCS-SF包含一个清单，有四个症状类别和五个严重程度项目，按0至8分评分，总分0至40分。数据收集自目前被诊断为强迫症的成年人（n = 204）和一个社区对照组（n = 211）。结果提供了内部一致性和收敛效度的证据，尽管区分效度的证据好坏参半。还发现了诊断敏感性和特异性以及治疗敏感性的证据。分析表明临界值为16分。总之，所获得的数据与在原始维度强迫症量表上发表的研究结果相似。有充分证据表明DOCS-SF在评估患有这种疾病的个体和非临床个体的强迫症症状方面具有可靠性和有效性。
