精神疾病信念量表的汉化及其在大学生群体中的信效度检验

Chinese version of the Beliefs Toward Mental Illness Scale and its reliability and validity in college students

目的对英文版的精神疾病信念量表(BTMI)进行汉化,并在大学生人群中检验中文版BTMI的信效度。方法遵循Beaton跨文化调试指南,形成中文版BTMI。采用便利抽样法,于2023年4—5月选取全国26个省、自治区、直辖市171所高校的915名大学生为研究对象进行问卷调查,对量表进行信效度分析。结果本研究共发放问卷915份,收回有效问卷814份,有效回收率为88.96%(814/915)。中文版BTMI量表共21个条目,总量表的Cronbach'sα系数为0.922,各维度的Cronbach'sα系数为0.745~0.921;总量表的折半信度系数为0.797;总量表的重测信度系数为0.903(P<0.01)。探索性因子分析共提取出4个公因子,分别为社会功能、危险性、不可治愈性、尴尬,累积方差贡献率为62.29%,验证性因子分析结果显示重要拟合指标均>0.900,整体模型拟合度较好。结论经汉化的中文版BTMI具有良好的信效度,可用于评估中国大学生对精神疾病的信念。

Objective To translate the English version of the Beliefs Toward Mental Illness Scale(BTMI)into Chinese and test the reliability and validity of the Chinese version in college students.Methods According to the Beaton cross-cultural adaptation guideline,the Chinese version of BTMI was formed.From April to May 2023,a questionnaire survey was conducted on 915 university students from 171 universities in 26 provinces,autonomous regions,and municipalities across China using convenience sampling,to analyze the reliability and validity of the scale.Results A total of 915 questionnaires were distributed,and 814 valid questionnaires were collected,with an effective recovery rate of 88.96%(814/915).The Chinese version of BTMI had a total of 21 items.The Cronbach'sαcoefficient of the total scale was 0.922,and the Cronbach'sαcoefficients of each dimension were 0.745 to 0.921.The half reliability coefficient of the total scale was 0.797,and the retest reliability coefficient of the total scale was 0.903(P<0.01).Exploratory factor analysis extracted four common factors,namely social function,risk,incurability,and awkwardness,with a cumulative variance contribution rate of 62.29%.Confirmatory factor analysis showed that all important fitting indicators were greater than 0.900,indicating a good overall model fit.Conclusions The Chinese version of BTMI has good reliability and validity,which can be used to evaluate the beliefs of Chinese university students about mental illness.
