BACKGROUND
To establish the validity and reliability of the Short Warwick Edinburgh Mental Well-being Scale (SWEMWBS) in service users with schizophrenia, depression and anxiety spectrum disorders in Singapore and estimate SWEMWBS scores across socio-demographic and the three psychiatric diagnostic groups in the sample.
METHODS
This secondary analysis was conducted using data from a study among outpatients of a tertiary psychiatric hospital. In addition to the SWEMWBS, socio-demographic data and current psychiatric diagnosis were collected. Service users were also administered the Global Assessment of Functioning (GAF), Patient Health Questionnaire (PHQ)-8, Generalised Anxiety Disorder (GAD)-7, Satisfaction with Life Scale (SWLS) and the Positive Mental Health (PMH) instrument. The SWEMWBS was tested for factorial validity, reliability and convergent and divergent validity.
RESULTS
In total, 350 service users with a mean (SD) age of 39.1 (11.1) years were included in this study of which 39.4%, 38.9% and 21.7% had schizophrenia, depression and anxiety spectrum disorders, respectively. The single factor structure of the SWEMWBS was confirmed by confirmatory factor analysis (CFI = 0.969, TLI = 0.954, RMSEA = 0.029). The internal consistency reliability was high (Cronbach's alpha = 0.89). The convergent and divergent validity testing revealed that the SWEMWBS scores had significant moderate to high positive correlations with GAF, SWLS and PMH scores and moderate negative correlations with (PHQ)-8 and (GAD)-7 scores. SWEMWBS scores were higher in married participants (22.2 (5.4) versus never married: 20.7 (5.3) and divorced/separated/widowed: 20.4 (5.1), p = 0.049) and among those with schizophrenia (22.8 (5.5) versus depression:19.6 (4.7) and anxiety spectrum disorders 20.9 (5.2), p < 0.001).
CONCLUSION
These results demonstrate adequate validity and reliability of the SWEMWBS in people with schizophrenia, depression and anxiety spectrum disorders in Singapore.
背景
为了确定简版沃里克-爱丁堡心理健康量表（SWEMWBS）在新加坡精神分裂症、抑郁症和焦虑谱系障碍患者中的有效性和可靠性，并估计样本中不同社会人口统计学特征及这三种精神疾病诊断组别的SWEMWBS得分。
方法
本二次分析使用了一家三级精神病医院门诊患者研究的数据。除了SWEMWBS外，还收集了社会人口统计学数据和当前的精神疾病诊断。对患者还进行了功能总体评定量表（GAF）、患者健康问卷（PHQ）-8、广泛性焦虑障碍（GAD）-7、生活满意度量表（SWLS）和积极心理健康（PMH）工具的测试。对SWEMWBS进行了因子效度、信度以及聚合效度和区分效度的检验。
结果
本研究共纳入350名患者，平均（标准差）年龄为39.1（11.1）岁，其中分别有39.4%、38.9%和21.7%的患者患有精神分裂症、抑郁症和焦虑谱系障碍。验证性因子分析证实了SWEMWBS的单因素结构（CFI = 0.969，TLI = 0.954，RMSEA = 0.029）。内部一致性信度较高（Cronbach's α = 0.89）。聚合效度和区分效度检验显示，SWEMWBS得分与GAF、SWLS和PMH得分呈显著的中度至高正相关，与（PHQ）-8和（GAD）-7得分呈中度负相关。已婚参与者的SWEMWBS得分更高（22.2（5.4），未婚者为20.7（5.3），离婚/分居/丧偶者为20.4（5.1），p = 0.049），精神分裂症患者的得分也更高（22.8（5.5），抑郁症患者为19.6（4.7），焦虑谱系障碍患者为20.9（5.2），p < 0.001）。
结论
这些结果表明SWEMWBS在新加坡精神分裂症、抑郁症和焦虑谱系障碍患者中具有足够的效度和信度。
