中文简版正念能力量表在多民族大学生中应用的信度和效度

Reliability and validity of the Short Inventory of Mindfulness Capability-Chinese version applied in multi-ethnic college students

[目的]评估中文简版正念能力量表(the Short Inventory of Mindfulness Capability,SIM-C)在多民族大学生中应用的信度和效度,为以正念为基础的相关研究提供测评工具。[方法]选取宁夏回族自治区大学生990名,采用随机数字表法选取495名学生进行探索性因子分析,余495名学生进行验证性因子分析;在总体样本中,采用抑郁焦虑压力量表(DASS-21)和多伦多述情障碍量表(TAS-20)检验校标效度;间隔4周,在总体样本中随机抽取137人重测,采用组内相关系数(ICC)检验重测信度。[结果]条目分析显示中文简版SIM-C的12个条目具有良好的区分度;探索性因子分析共提取有意识行动、描述和不判断3个因子,累积贡献率为56.63%;验证性因子分析显示量表结构拟合好;SIM-C量表总分与DASS-21的抑郁、焦虑、压力及TAS-20的情感辨别不能、情感描述不能和外向性思维得分呈负相关(P<0.01);多元回归分析显示,有意识行动和描述是抑郁、焦虑和压力的影响因素。量表总分和各维度的Cronbach′sα系数为0.614～0.798;重测ICC为0.571～0.636(P<0.01)。[结论]中文简版SIM-C应用于多民族大学生群体中有较好的效度和信度,可作为正念能力相关研究的测评工具。

Objective:To evaluate the reliability and validity of the Short Inventory of Mindfulness Capability Chinese version(SIM C)applied in multi ethnic college students,in order to provide measurement tools for studies related to mindfulness.Methods:A total of990college students in the Ningxia Hui Autonomous Region were selected,495students were selected by random number table for exploratory factor analysis,and the other495students for confirmatory factor analysis.The criterion validity was tested by the Depression Anxiety Stress Scale(DASS21)and the Toronto Alexithymia Scale(TAS20).At a four week interval,137students were randomly selected from the overall sample for retest,and the retest reliability was tested by the inter group correlation coefficient(ICC).Results:Item analysis showed that12items of SIM C had good degree of differentiation.Exploratory factor analysis extracted three factors of acting with awareness,describe and no judge,and the cumulative contribution rate was56.63%.The confirmatory factor analysis showed that the scale structure fitted well.The total score of SIM C was negatively correlated with the depression,anxiety,stress of DASS21and the inability to recognize emotions,the inability to describe emotions and the extraversion thinking of TAS20(P<0.01).Multiple regression analysis showed that acting with awareness and describe were factors that affected depression,anxiety and stress.Cronbach′sαcoefficient of the total score and each dimension was0.614~0.798.The ICC was0.571~0.636(P<0.01).Conclusions:SIM C had good validity and reliability in the multi ethnic college students,and could be used as a measurement tool for research on mindfulness.
