Many variables influencing quality of life (QOL) for outpatients with schizophrenia have been identified from prior studies. Symptom severity, psychosocial rehabilitation activities, and empowerment have all been clearly identified as key variables. However, which variables are the most influential and important factors remains unknown; factors influencing QOL, either directly or indirectly and to what degree, need to be examined. The aim of this study was to test the hypothesis that empowerment is a possible mediator of how (a) psychiatric symptoms and (b) psychosocial rehabilitation activities affect QOL for outpatients with schizophrenia in the community. We used the probability proportional to size random sampling for 190 outpatients with schizophrenia at 10 community rehabilitation centers in Taipei, such that samples consisted of adults who fulfilled the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria. The instruments included the questionnaire to gather demographic and disease information, the Empowerment Scale, the Psychiatric Symptoms Scale, the psychosocial rehabilitation activity (PRA), and the Quality of Life Scale for Psychiatric Patients. Beyond descriptive statistics, correlation and structural equation models were computed. Findings showed that empowerment in outpatients with schizophrenia mediates QOL, whereas psychosocial rehabilitation activities seem to increase empowerment, which may in turn increase QOL. Psychotic symptoms seem to have a direct effect of decreasing QOL that could not be mediated by empowerment. Empowerment had a significant effect on QOL for outpatients with schizophrenia. The findings of this study support the importance of empowerment and rehabilitation activities for promoting QOL among community outpatients. We suggest that various rehabilitation programs and empowerment health education are needed to enhance QOL for schizophrenia outpatients in the community.
先前的研究已经确定了许多影响精神分裂症门诊患者生活质量(QOL)的变量。症状严重程度、心理社会康复活动和赋权都被明确确定为关键变量。然而,哪些变量是最有影响力和最重要的因素尚不清楚;需要检查影响 QOL 的因素,无论是直接还是间接,以及影响程度。本研究旨在检验以下假设:赋权是精神病症状和心理社会康复活动影响社区精神分裂症门诊患者 QOL 的一种可能的中介因素。我们使用大小概率比例随机抽样方法,对台北 10 个社区康复中心的 190 名精神分裂症门诊患者进行抽样,样本包括符合《精神障碍诊断与统计手册》第四版标准的成年人。使用的工具包括收集人口统计学和疾病信息的问卷、赋权量表、精神病症状量表、心理社会康复活动(PRA)和精神科患者生活质量量表。除了描述性统计数据外,还计算了相关性和结构方程模型。研究结果表明,精神分裂症门诊患者的赋权可以调节 QOL,而心理社会康复活动似乎可以增加赋权,进而提高 QOL。精神病症状似乎对 QOL 有直接的降低作用,无法通过赋权来调节。赋权对精神分裂症门诊患者的 QOL 有显著影响。本研究的结果支持赋权和康复活动对提高社区门诊患者 QOL 的重要性。我们建议需要各种康复计划和赋权健康教育,以提高社区精神分裂症门诊患者的 QOL。
