二维自尊量表修订版在中学生群体中的信效度检验

Reliability and validity of the Self-liking/Self-competence Scale-Revised in Chinese middle school students

目的:对二维自尊量表修订版(SLCS-R)在中学生群体中进行信效度检验,为研究中学生自尊提供可靠有效的测量工具。方法:通过4次抽样,初测调查561人进行SLCS-R条目初步修改;再测调查779人进行探索性因素分析形成正式中文SLCS-R量表;正式调查1862人,一部分被试完成SLCS-R和罗森博格自尊量表(RSES)、容纳他人量表(AOS)、一般自我效能感量表(GSES)来考核聚会效度与区分效度,另两组被试除完成SLCS-R外,分别完成考试焦虑量表(FAT)或生活满意度量表(LSA)来考核效标效度。此外,抽取其中271人进行验证性因素分析,111人在4周后进行重测。结果:中文版SLCS-R分为自我悦纳和自我能力两个维度,每维度8个条目。总量表和分量表的α系数在0.75～0.85之间;4周重测组内相关系数在0.73～0.80之间;考虑方法学效应后的主要适配度指标χ2/df=1.37,GFI=0.95,CFI=0.97,RM SEA=0.04;SLCS-R与RSES的相关为0.67,与AOS的相关为0.37,与GSES的相关为0.51,与FAT的相关为-0.50,与LSA的相关为0.48(均P<0.01)。结论:二维自尊量表具有较好的信效度,是测量中学生自尊的适宜工具。

Objective： To test the reliability and validity of Self-Liking/Self-Competence Scale-Revised （SLCS-R） in Chinese middle school students. Methods： Totally 3202 middle school students were recruited by four samplings. The first sample included 561 participants, primarily modifying the items of SLCS-R based on two-way translation. Then, 779 students were assessed for exploratory factor analysis. Finally, 1862 students were formerly assessed with the Chinese version of SLCS-R. Some of them completed the Self-Esteem Scale （SES）, Acceptance Others Scale （AOS）, General Self-Efficacy Scale （GSES） to test the convergent validity and discriminant validity. Other two groups completed the Friedman Test Anxiety Scale （FAT） and Life Satisfaction of Adolescent （LSA） to test the criterion validity. Totally 271 students were selected for the confirmatory factor analysis, and 111 students were re-tested 4 weeks later for test-retest reliability. Results： The Chinese Version of SLCS-R consisted of two 8-item subscale： self-liking and self-competence. The confirmatory factor analysis supported the two factor model 0（2/ df= 1.37, GFI =0. 95, CFI =0. 97, RMSEA =0. 04）. The Cronbach＇s alpha coefficient of the SLCS-R and all subscales were range from 0. 75 to 0. 85. The test-retest reliabilities （4 weeks interval） were 0. 73 -0. 80 （ICC）. For the total score of SLCS-R, the correlation coefficients were 0. 67 to SES, 0. 51 to GSES, 0. 37 to AOS, - 0. 50 to FAT and 0. 48 to LSA （Ps 〈0. 01）. Conclusion： It suggests that the Chinese Version of SLCS-R is a reliable and valid instrument for assessing self-esteem in middle school students.
