RESUMEN
Objective To conduct item analysis on Work Attitude Scale(Wa) and to develop a short-versioned scale.Methods Wa and Symptom Checklist 90(SCL-90) were administered to 3767 recruits,item analysis of Wa was conducted and short version of Wa was developed based on the results of item analysis,Cronbach' s αcoefficient of the original scale and the short-versioned scale was calculated,criterion validity of the original scale and the short-versioned scale was analyzed using SCL-90 as the validity criterion.For other samples,16 Personality Factor Questionnaire (16PF),Eysenck Personality Questionnaire ( EPQ),and Self-Rating Anxiety Scale (SAS) were tested while the short-versioned scale was tested at the same time,criterion validity of the short-versioned Wa was analyzed using 16PF,EPQ,and SAS as the validity criterion.Results Difficulty of the original scale was from 0.03 to 0.87,27 items' difficulty was less than 0.20 or greater than.Discrimination index was from 0.04 to 0.56,22 items' discrimination index was less than 0.30.Correlation coefficient of the item score and the total score is from 0.02 to 0.52,18 items' correlation coefficient was less than 0.30.The short-versioned scale was made up of the 18 items with better quality.Cronbach' s α coefficient of the original scale and the short-versioned scale was 0.778 and 0.789,respectively.Both the total score of the original scale and the short-versioned scale were significantly correlated with the scores of SCL-90,and all the correlation coefficient were above 0.40.The correlation coefficient between the score of the short-versioned scale and that of the original scale was 0.934.The correlation coefficient between the score of the short-versioned scale and 16PF,EPQ,SAS was significant.Conclusion The short-versioned scale has a higher reliability and good validity.
RESUMEN
Objective: To make an English Learning Anxiety Scale (ELAS) based on the Foreign Language Classroom Anxiety Scale (FLCAS) and to do a psychometric test of the ELAS. Method: After translation of the FLCAS into Chinese and did item adaptation to form an ELAS. It was administered to 669 college students with major field other than English. Result: The ELAS was composed of 23 items in four subscales: nervousness , worry, apprehension of being questioned, and sense of anxiety.Factor loadings in the exploratory factor analysis were: A1, 0.46-0.70; A2, 0.53-0.73; A3, 0.55-0.70, A4,0.50-0.67. 48.95% of the total variance could explained. The Cronnbach?is 0.70-0.89, split-half reliability(S-B), 0.71-0.88. ?2/df, RMSEA, GFI, AGFI, NFI, NNFI, CFI, IFI of the goodness of fit indices of confirmatory factor analysis were 2.40, 0.05, 0.92, 0.90, 0.85, 0.89, 0.90, 0.90. The correlation coefficient between ELAS and CET4 score is-0.25~0.64. The correlation coefficient between ELAS and the subscales was 0.69~0.80. The correlation coefficient between the subscales was 0.45~0.63. Conclusion: ELAS has good reliability and validity, could be an effective research instrument in studying anxiety of Chinese college students with major field other than English.
