Despite the prevalence of obsessive-compulsive disorder (OCD), its precise identification remains challenging. With the Zohar-Fineberg Obsessive-Compulsive Screen (ZF-OCS; 5 or 6 items), a brief instrument is widely available mainly in English. As there is a lack of empirical studies on the ZF-OCS, the aim of the present study was to translate the items into German and investigate the instrument in a nonclinical sample. In two consecutive online surveys, n = 304 and n = 51 students participated. Besides the ZF-OCS, they answered established measures on OCD, depression, health anxiety, general anxiety and health-related well-being. Whereas internal consistency was low (α = .53–.72; ω = .55–.69), retest reliability (rt1,t2 = .89) at two weeks was high. As expected, we found high correlations with other OCD instruments (r > .61; convergent validity), and significantly weaker correlations with measures of depression (r = .39), health anxiety (r = .29), and health-related well-being (r = −.28, divergent validity). Nonetheless, the correlations with general anxiety were somewhere in between (r = .52). Due to heterogeneous OCD subtypes, the ZF-OCS asks diverse questions which probably resulted in the present internal consistency. Nevertheless, the results on retest reliability and validity were promising. As for other OCD instruments, divergent validity regarding general anxiety seems problematic to establish. Even so, the ZF-OCS seems valuable for screening purposes, as it is short and easy to administer, and may facilitate initiating subsequent clinical assessment. Further studies should determine the instrument’s diagnostic accuracy.

认识强迫症：德国Zohar-Fineberg强迫症筛查仪有多合适？


尽管强迫症（OCD）很普遍，但其精确识别仍然具有挑战性。通过 Zohar-Fineberg 强迫症筛查（ZF-OCS；5 或 6 项），可以广泛使用一种主要以英文形式提供的简短工具。由于缺乏对 ZF-OCS 的实证研究，本研究的目的是将这些项目翻译成德语并在非临床样本中研究该仪器。在连续两次在线调查中，分别有 n = 304 和 n = 51 名学生参与。除了 ZF-OCS 之外，他们还回答了关于强迫症、抑郁、健康焦虑、一般性焦虑和健康相关幸福感的既定措施。尽管内部一致性较低 (α = .53–.72; ω = .55–.69)，两周时的重新测试可靠性 (rt1,t2 = .89) 却很高。正如预期的那样，我们发现与其他强迫症工具的相关性很高（r > .61；收敛效度），而与抑郁症 (r = .39)、健康焦虑 (r = .29) 和健康相关指标的相关性明显较弱。幸福感（r = −.28，有效性发散）。尽管如此，与一般性焦虑的相关性介于两者之间 (r = .52)。由于 OCD 亚型异质，ZF-OCS 提出了不同的问题，这可能导致了目前的内部一致性。尽管如此，重新测试的信度和效度结果还是有希望的。至于其他强迫症工具，关于一般性焦虑的不同有效性似乎难以确定。即便如此，ZF-OCS 似乎对于筛查目的很有价值，因为它简短且易于管理，并且可能有助于启动后续临床评估。进一步的研究应该确定仪器的诊断准确性。
