This study examines the factor structure of the Schizophrenia Quality of Life Scale Revision 4 (SQLS-R4) for inpatients with schizophrenia in a psychiatric hospital in southern Taiwan. All the participants ( = 100) filled out the SQLS-R4, Mini Mental Status Examination (MMSE), and Brief Psychiatric Rating Scale (BPRS) under the supervision of one experienced occupational therapist. Using confirmatory factor analysis, we first determined that a 29-item model was more satisfactory than the original 33-item model based on the findings of better fit indices for the 29-item model. We then found that a three-correlated-factor structure was best for the SQLS-R4 after four models (namely, two-correlated-factor, three-correlated-factor, seven-correlated-factor, and second-order models) had been compared. In addition, the three constructs (psychosocial, physical, and vitality) were moderately to highly correlated with the constructs of the World Health Organization Quality of Life- (WHOQOL-) BREF ( = -0.38 to -0.69), except for one low correlation between the vitality construct of the SQLS-R4 and the psychological construct of the WHOQOL-BREF ( = -0.26). We tentatively conclude that the SQLS-R4 with a three-correlated-factor structure is a valid and reliable instrument for examining the quality of life of people with schizophrenia.
本研究探讨台湾南部一家精神病院精神分裂症住院患者的《精神分裂症生活质量量表修订版4》（SQLS-R4）的因子结构。所有参与者（n = 100）在一名经验丰富的职业治疗师的监督下填写了SQLS-R4、简易精神状态检查表（MMSE）和简明精神病评定量表（BPRS）。使用验证性因子分析，基于29项模型具有更好的拟合指数这一结果，我们首先确定29项模型比原始的33项模型更令人满意。在比较了四个模型（即二相关因子、三相关因子、七相关因子和二阶模型）之后，我们发现三相关因子结构最适合SQLS-R4。此外，除了SQLS-R4的活力构念与WHOQOL-BREF的心理构念之间存在一个低相关性（r = -0.26）外，三个构念（心理社会、身体和活力）与世界卫生组织生活质量量表简表（WHOQOL-BREF）的构念具有中度到高度相关性（r = -0.38至-0.69）。我们初步得出结论，具有三相关因子结构的SQLS-R4是一种有效且可靠的工具，可用于评估精神分裂症患者的生活质量。
