The aim of this study was to evaluate the psychometric properties of the Beliefs Toward Mental Illness Scale (BMI) across women from the United States, Japan, and South Korea.
A cross-sectional study design was employed. The sample was 564 women aged 21-64 years old who were recruited in the United States and Korea (American = 127, Japanese immigrants in the United States = 204, and Korean = 233). We carried out item analysis, construct validity by confirmatory factor analysis (CFA), and internal consistency using SPSS Version 22 and AMOS Version 22.
An acceptable model fit for a 20-item BMI (Beliefs Toward Mental Illness Scale-Revised [BMI-R]) with 3 factors was confirmed using CFA. Construct validity of the BMI-R showed to be all acceptable; convergent validity (average variance extracted [AVE] ≥0.5, construct reliability [CR] ≥0.7) and discriminant validity (r = .65-.89, AVE >.79). The Cronbach's alpha of the BMI-R was .92.
These results showed that the BMI was a reliable tool to study beliefs about mental illness across cultures. Our findings also suggested that continued efforts to reduce stigma in culturally specific contexts within and between countries are necessary to promote help-seeking for those suffering from psychological distress.
本研究旨在评估美国、日本和韩国女性群体中精神疾病信念量表（BMI）的心理测量特性。
采用横断面研究设计。样本为564名年龄在21至64岁之间的女性，她们分别来自美国和韩国（美国女性127名、在美国的日本移民女性204名、韩国女性233名）。我们使用SPSS 22版和AMOS 22版进行了项目分析、通过验证性因素分析（CFA）检验结构效度以及检验内部一致性。
使用CFA验证了一个适用于包含3个因素的20项BMI（修订版精神疾病信念量表[BMI-R]）的可接受模型拟合度。BMI-R的结构效度显示均为可接受；聚合效度（平均提取方差[AVE]≥0.5，结构信度[CR]≥0.7）和区分效度（r = 0.65 - 0.89，AVE > 0.79）。BMI-R的克朗巴哈系数为0.92。
这些结果表明，BMI是研究跨文化精神疾病信念的可靠工具。我们的研究结果还表明，有必要持续努力在国家内部和国家之间的特定文化背景下减少污名化，以促进那些遭受心理困扰的人寻求帮助。
