To compare schizophrenia-specific quality of life measures, this study examined an 18-item Chinese version of 41-item Quality of Life Questionnaire in Schizophrenia (S-QoL; S-QoL-18-C) using 41 patients. The S-QoL-18-C was validated and compared with Schizophrenia Quality of Life Scale-Revision 4 (SQLS-R4). Index scores of S-QoL-18-C showed nearly identical psychometrics to S-QoL-C and S-QoL-18. No significant ceiling/floor effects were found, except with psychological and selfesteem subscales. Internal consistency was acceptable for whole scale and all subscales, except family relationships and sentimental life. Test-retest reliability was moderate to high (ICC=0.58-87). Score distributions and reliability of S-QoL-18-C were slightly lower than those of S-QoL-C. Convergent validity was supported by satisfactory correlations between subscales/index scores of S-QoL-18-C and similar scales (r=∣-0.35 ∣ to 0.80) and between corresponding subscales in S-QoL-18-C and S-QoL-C (r=0.85-0.97). S-QoL-18-C and SQLS-R4 demonstrated discriminant validity by differentiating among 30 patients with symptom remission, 30 patients without symptom remission, and 30 healthy individuals. Two patient groups were classified by criteria proposed by Remission in Schizophrenia Working Group. Three groups were controlled for five factors. Furthermore SQLS-R4, but not S-QoL-18-C, differentiated between patient groups with different hospitalization frequencies. Overall, S-QoL-18-C and SQLS-R4 show different advantages psychometrically.
为了比较精神分裂症特异性的生活质量测量工具，本研究使用 41 名患者对 41 项精神分裂症生活质量问卷（S-QoL）的 18 项中文版本（S-QoL-18-C）进行了检验。S-QoL-18-C 经过验证并与精神分裂症生活质量量表修订版 4（SQLS-R4）进行了比较。S-QoL-18-C 的指数得分与 S-QoL-C 和 S-QoL-18 具有几乎相同的心理测量学特性。除了心理和自尊分量表外，没有发现明显的天花板/地板效应。除了家庭关系和情感生活分量表外，整个量表和所有分量表的内部一致性都是可以接受的。测试-重测信度为中度至高度（ICC=0.58-87）。S-QoL-18-C 的分数分布和信度略低于 S-QoL-C。S-QoL-18-C 的子量表/指数得分与类似量表（r=∣-0.35∣至 0.80）以及 S-QoL-18-C 和 S-QoL-C 中的相应子量表之间存在满意的相关性，这支持了其聚合效度（r=0.85-0.97）。S-QoL-18-C 和 SQLS-R4 通过区分 30 名症状缓解患者、30 名未缓解症状患者和 30 名健康个体来证明其具有判别效度。两组患者按照精神分裂症缓解工作组提出的标准进行分类。三组患者在五个因素方面进行了控制。此外，SQLS-R4 可以区分住院频率不同的患者组，而 S-QoL-18-C 则不能。总体而言，S-QoL-18-C 和 SQLS-R4 在心理测量学方面具有不同的优势。
