衡量精神分裂症患者认知功能障碍的测试组合，即精神分裂症认知简要评估（BACS），已被翻译成多种语言并经过验证。本研究旨在测试中文版 BACS 在华语人群中的信度和效度。本研究的所有参与者（66 名精神分裂症患者[平均年龄：41.2 岁，57.6% 男性]和 66 名年龄和性别匹配的健康对照）均来自台湾，并使用 BACS 和加州大学圣地亚哥分校 (UCSD) 基于绩效的技能评估，简要版 (UPSA-B) 进行评估。 66 名精神分裂症患者中的 38 名接受了 BACS 的重新评估。 BACS 具有良好的重测信度，并且所有 BACS 子测试的实践效果在统计上均不显着。主成分分析表明，单因素解决方案最适合我们的数据集（方差为 60.9%）。在患者和对照组中，BACS 综合评分与所有 BACS 子量表（P<0.001）和 UPSA-B 量表（P<0.001）呈正相关。此外，所有BACS子测试（语言记忆、工作记忆、运动速度、语言流畅性、注意力和处理速度以及执行功能）均显着区分精神分裂症患者与健康对照（P<0.001），并且BACS综合评分具有最佳区分效度（P<0.001）。中文版BACS表现出令人满意的心理测量特性，包括高重测信度、高内部一致性、可接受的并发效度和良好的区分效度。我们认为 BACS 是评估精神分裂症患者认知功能的可靠且实用的工具。
A test battery that measures cognitive function impairment in patients with schizophrenia, the Brief Assessment of Cognition in Schizophrenia (BACS), has been translated into various languages and validated. This study aimed to test the reliability and validity of the Chinese version of the BACS in a Chinese-speaking population. All participants in this study (66 patients with schizophrenia [mean age: 41.2 years, 57.6% male] and 66 age- and sex-matched healthy controls) were from Taiwan and assessed using the BACS and the University of California, San Diego (UCSD) Performance-Based Skills Assessment, Brief Version (UPSA-B). Thirty-eight of the 66 patients with schizophrenia received a reassessment using the BACS. The BACS had good test–retest reliability, and all BACS subtests had statistically insignificant practice effects. Principal components analysis demonstrated that a one-factor solution best fits our dataset (60.9% of the variance). In both patients and controls, the BACS composite scores were positively correlated with all BACS subscales (P<0.001) and UPSA-B scales (P<0.001). Furthermore, all BACS subtests (verbal memory, working memory, motor speed, verbal fluency, attention and processing speed, and executive function) significantly differentiated patients with schizophrenia from healthy controls (P<0.001), and the BACS composite score had the best discriminative validity (P<0.001). The Chinese version of the BACS exhibits satisfactory psychometric properties, including high test–retest reliability, high internal consistency, acceptable concurrent validity, and good discriminant validity. We suggest that the BACS is a reliable and practical tool for assessing cognitive function in patients with schizophrenia.
