This study was performed to test the validity and value of the Schizophrenia Quality of Life Scale as an assessment tool in a Japanese-language version (JSQLS). The subjects for the present study were 55 inpatients with a diagnosis of schizophrenia as defined by DSM-IV. The JSQLS was administered together with two other self-report measures, the Medical Outcomes Study 36-item short-form health survey questionnaire (SF-36) and the WHO QOL-26, to assess validity. Psychotic symptoms and extrapyramidal symptoms were assessed using the BPRS and the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS), respectively. All the scales (psychosocial, motivation/energy and symptoms/side effects) showed good internal consistency reliability (Cronbach's alpha=0.93, 0.73 and 0.80, respectively). The correlations of items with their scale total revealed that almost all items were significantly correlated with their own scale score. There were associations with relevant SF-36, WHO QOL-26, and DIEPSS scores. From the results of the testing of the reliability and validity of the JSQLS, it is concluded that the JSQLS is a simple and reliable scale.
本研究旨在测试精神分裂症生活质量量表日语版（JSQLS）作为一种评估工具的有效性和价值。本研究的受试者为55名根据《精神疾病诊断与统计手册》第四版（DSM-IV）诊断为精神分裂症的住院患者。JSQLS与另外两项自我报告测量工具，即医学结局研究36项简短健康调查问卷（SF-36）和世界卫生组织生活质量量表简表（WHO QOL-26）一起使用，以评估有效性。分别使用简明精神病评定量表（BPRS）和药物所致锥体外系症状量表（DIEPSS）评估精神病性症状和锥体外系症状。所有量表（心理社会、动机/精力和症状/副作用）均显示出良好的内部一致性信度（Cronbach's α分别为0.93、0.73和0.80）。各项目与其量表总分的相关性表明，几乎所有项目与其自身量表得分均显著相关。与相关的SF-36、WHO QOL-26和DIEPSS得分存在关联。从JSQLS的信度和效度测试结果得出结论，JSQLS是一个简单可靠的量表。
