1.The structural study of the simple study process questionnaire
Chinese Journal of Behavioral Medicine and Brain Science 2009;18(5):465-467
Objective To examine whether the revised two-factor Study Process Questionnaire (SPQ-R-2) accords with four-factor model or two-dimension model in Chinese college students' learning situation. Methods Questionnaire survey was used and 1029 college students from three universities participated in the investigation were assessed with the Chinese version of (SPQ-R-2). Then correlation analysis and exploratory and Confirmatory factor analysis were conducted. Results The α coefficients of SPQ-R-2 ranged from 0.539 to 0.767. The correlation coefficients of inter-dimension ranged from -0.137 to -0.200,and the correlation coefficients of intra-dimension ranged from 0.557 to 0.918. Exploratory factor analysis using 515 samples showed SPQ-R-2 Chinese vision had four factors which could explain 45.023% variance and the loading of factors varied from 0.431 to 0.761.Confirmatory factor analysis using 514 samples indicated that the four-factor model and two-dimension model were the most fit models (χ2/df<5,RMSEA<0.08,ECVI value of approximately 1,AGFI value of approximately 0.90). Conclusion The SPQ-R-2 show good reliability and constructive validity. Four-factor model and two-dimension model have been proved free in China. The SPQ-R-2 is a reliable and valid measurement for assessing the study process of the Chinese college students.
2.Development of the Virtue Adjectives Rating Scale and Research on Its Reliability and Validity
Chinese Journal of Clinical Psychology 2001;0(03):-
Objective: To develop the virtue adjectives rating scale and to test the reliability and validity of the scale.Methods: Adjectives describing virtues were selected through the psycholexical approach.Psychological structure of the virtues and the virtue adjectives rating scale was established by means of exploratory factor analysis;reliability analysis and correlation analysis were used to test the internal consistency reliability,split reliability,test-retest reliability,construct validity and criterion-related validity;and confirmatory factor analysis was used to compare fitness of the models.Results: 109 adjectives describing virtues were selected through the psycholexical approach.By exploratory factor analysis,19 items were deleted;the 90 adjectives items left could be explained by 5 big scales and 14 subscales with a 46.37 percent contribution to the variance.All the scales' internal consistency reliability,split reliability,test-retest reliability and the correlation coefficient were 0.75-0.95,0.74-0.90,0.44-0.75,-0.13-0.42 respectively.The result showed that the scale was high in validity as convergent validity,discriminant validity and criterion-related validity;and confirmatory factor analysis validated the three class model.Conclusion: The virtue adjectives rating scale had good reliability and validity;its effectiveness need to be tested through other approaches.
