Schizophrenia is a chronic, complex, and severe mental disorder and caregivers having knowledge about it can help improve patient adherence to treatment. This study aims to translate the Knowledge About Schizophrenia Test (KAST) into a Chinese Mandarin version and test it among caregivers to validate its reliability and reproducibility, as well as to determine its associated sociodemographic factors and clinical factors.
The project surveyed 160 patients with schizophrenia and their caregivers at four community health facilities in Beijing, China, from January 2022 to February 2022. All patients and caregivers completed the sociodemographic questionnaire, and caregivers also completed the Chinese-version KAST, and 143 of these caregivers completed the Chinese-version KAST again 2-4 weeks later.
The mean (SD) of the caregiver score was 11.49 (± 3.13). After item analysis, there was acceptable internal consistency among the 17 items in the Chinese version (KR-20 coefficient 0.702). The intraclass correlation coefficient in the retest (0.686) was statistically significant. Gender, educational attainment, marital status, relationship with the patient, and occupational status were associated with the KAST score.
The findings demonstrate that the Chinese-version KAST is a reliable and reproducible instrument that can measure knowledge about schizophrenia and is valid to be applied in schizophrenia research.
精神分裂症是一种慢性、复杂且严重的精神障碍，了解它的照顾者可以帮助提高患者对治疗的依从性。本研究旨在将精神分裂症知识测试（KAST）翻译成简体中文版本，并在照顾者中进行测试，以验证其可靠性和可重复性，以及确定其相关的社会人口学因素和临床因素。
该项目于 2022 年 1 月至 2 月在中国北京的四家社区卫生机构调查了 160 名精神分裂症患者及其照顾者。所有患者和照顾者都完成了社会人口学问卷，照顾者还完成了简体中文版 KAST，其中 143 名照顾者在 2-4 周后再次完成了简体中文版 KAST。
照顾者得分的平均值（标准差）为 11.49（±3.13）。经过项目分析，简体中文版的 17 个项目具有可接受的内部一致性（KR-20 系数 0.702）。重测的组内相关系数（0.686）具有统计学意义。性别、受教育程度、婚姻状况、与患者的关系和职业状况与 KAST 评分相关。
研究结果表明，简体中文版 KAST 是一种可靠且可重复的测量精神分裂症知识的工具，可用于精神分裂症研究。
