Psychometric Performance of Learning Burnout Scale for Undergraduates (LBSU) in Guangdong

Abstract

To analyze the psychometric performance of Learning Burnout Scale for Undergraduates (LBSU) in Guangdong province． LBSU was used to conduct the survey involing 1628 undergraduates who were selcted with stratified random sampling from 7 colleges in Guangdong province. Cronbach's α coefficient and split-half reliability were used to analyze the internal consistency of the questionnaire．Convergent validity, discriminant validity and factor analysis were used to evaluate its structural validity. Celling and floor effect were used to analyze its sensitivity. Cronbach's α coefficient of the total questionniar was 0.89 and cronbach's α coefficient of 3 dimensions were 0.73-0.78, which met with the requirements of the group comparison. Spearman - Brown split-half coefficient of the total questionniar and 3 dimensions were 0.90, 0.85, 0.81, 0.79, respectively, which also met with the requirements of the group comparison. Both the calibration success rate of convergent validity and discriminant validity of each dimension were 100%. Four components obtained from 20 items which cumulative variance contribution rate was 51.924%. The total score and score of each dimension were all normal distribution, without any floor or celling effect in dimensions. The psychometric performance of LBSU for assessing undergraduates in Guangdong province is valid and reliable．
