Objectives. To validate the Schizophrenia Quality of Life Scale Revision 4 (SQLS-R4) Chinese version with factor analysis. We also investigated factors influencing quality of life results. Method. One hundred patients with schizophrenia participated in this study. Experienced psychiatrists evaluated each patient's current psychological condition to assure intact judgment. Participants then filled out the quality of life questionnaire, SQLS-R4. We used principal component analysis to analyze SQLS-R4 with oblique rotation. We also collected demographic data, another subjective and objective quality of life questionnaire, and information about the functional status of the participants at the same time. Multiple linear regression was used to analyze collected factors which may influence the quality of life of schizophrenic patients. Results. We extracted seven factors that explained a 68.1% variance in the patients' quality of life. The factors were relationships with others, loneliness, exhaustion, depressed thinking, somatic concerns, vitality, and worry. Conclusion. We found that the SQLS-R4 factor analysis provided insights into the structure of the quality of life of patients with schizophrenia. We also found that subjective social participation, subjective health, and depression were quality-of-life-related factors. Whether other factors influence the quality of life in patients with schizophrenia requires further investigation.
目的。使用因子分析验证精神分裂症生活质量量表修订版 4 （SQLS-R4）中文版。我们还研究了影响生活质量结果的因素。方法。100 名精神分裂症患者参加了这项研究。经验丰富的精神科医生评估了每位患者的当前心理状况，以确保判断完整。然后，参与者填写生活质量问卷，SQLS-R4。我们使用主成分分析对 SQLS-R4 进行斜交旋转分析。我们还同时收集了人口统计学数据、另一个主观和客观的生活质量问卷，以及参与者的功能状态信息。使用多元线性回归分析可能影响精神分裂症患者生活质量的收集因素。结果。我们提取了七个因子，解释了患者生活质量的 68.1%的方差。这些因素是与他人的关系、孤独感、疲惫感、抑郁思维、躯体担忧、活力和担忧。结论。我们发现 SQLS-R4 的因子分析深入了解了精神分裂症患者生活质量的结构。我们还发现主观社会参与、主观健康和抑郁是与生活质量相关的因素。其他因素是否会影响精神分裂症患者的生活质量需要进一步研究。
