背景：佛罗里达强迫症量表（FOCI）是一种自我报告测量，旨在评估强迫症症状的存在和严重程度。本研究评估了中国版FOCI的信度和效度，以及它的最佳分值。方法：采用系统的翻译过程将英文FOCI翻译成中文。453名成年人参与了这项研究，其中包括153名强迫症患者，150名患有原发性焦虑或抑郁症的病例对照，以及150名健康对照。采用耶鲁-布朗强迫症量表（Y-BOCS）、FOCI、强迫症量表修订版（OCI-R）、贝克抑郁量表第二版（BDI-II）、贝克焦虑量表（BAI）和简短健康调查（SF-36）对三组进行评估。在强迫症患者中，对47名参与者进行了为期两周的评估，以评估FOCI的重测可靠性。结果：强迫症组FOCI症状检查表和严重程度量表的内部一致性分别为0.813和0.840。两周重测信度分别为0.934和0.935。FOCI症状检查表和严重程度量表的收敛效度均较强。总体而言，与分化构念的相关性不大。对FOCI严重程度量表进行了因子分析，发现单因素解决方案解释了62.3%的方差。强迫症组的FOCI得分高于病例对照组和健康对照组。8分是预测病例的最佳分值。结论：中文版FOCI具有良好的心理测量特性，包括内部一致性、重测信度、稳定的因子结构、收敛效度和发散效度。8分是预测病例的最佳分值。
Background: The Florida Obsessive-Compulsive Inventory (FOCI) is a self-report measure designed to assess obsessive-compulsive symptom presence and severity. This study evaluated the reliability and validity of the Chinese version of the FOCI and its optimal cut-off score. Methods: A systematic translation process was used to translate the English FOCI into Chinese. Four hundred and fifty-three adults participated in the study including 153 individuals with OCD, 150 case-controls with a primary anxiety or depressive disorder, and 150 healthy controls. All three groups were evaluated by a set of measures including the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the FOCI, the Obsessive-Compulsive Inventory Revised (OCI-R), the Beck Depression Inventory-Second Edition (BDI-II), the Beck Anxiety Inventory (BAI), and the Short Form Health Survey (SF-36). Among the OCD patients, a subset of 47 participants were evaluated over a two-week interval to assess test-retest reliability of the FOCI. Results: The internal consistency of the FOCI Symptom Checklist and Severity Scale in the OCD group were0.813 and 0.840. Two-week test-retest reliability were 0.934 and 0.935. Convergent validity of the FOCI Symptom Checklist and Severity Scale were both strong. Correlations with diverging constructs were modest overall. Factor analysis of the FOCI Severity Scale was conducted, identifying a single factor solution explaining 62.3% of the variance. FOCI scores among those in the OCD group were higher than those from the case-control and healthy control groups. A cut-off score of 8 was optimal in predicting caseness. Conclusions: The Chinese version of the FOCI demonstrated good psychometric properties including internal consistency, test-retest reliability, a stable factor structure, and convergent and divergent validity. A cut-off score of 8 was optimal in predicting caseness.
