The Development of a Social intelligence Scale for Students in the Faculty of Education, Thailand National Sports University, AngThong Campus

Abstract

The objective of this research was to develop a social intelligence scale for students in the Faculty of Education, Thailand National Sports University, AngThong Campus. The sample group comprised students in the Faculty of Education, Thailand National Sports University, AngThong Campus during academic Year 2020. Included were 359 people from all population groups. The instrument was a social intelligence questionnaire with items measured on a          5 point Likert scale. The quality of the test was examined by content validity, discriminating powers, construct
validity and reliability. The results of the research found that thirty-one items on the social intelligence scale had content validity index (IOC range from 0.60 to 1.00).        The discriminating powers ranged from 2.32 – 11.13 and were statistically significant at 0.05, while the Corrected Item-Total Correlation (CITC) ranged between 0.21 – 0.70. For the discriminating powers of the social intelligence scale, twenty-four items ranged from 6.50 – 13.53 and were statistically significant at 0.05, while the Corrected Item-Total Correlation ranged from 0.34 – 0.65. The confirmatory factor analysis that was created fit the empirical data    ( X²= 1.21; df = 4; P = 0.88; GFI = 1.00; AGFI = 0.99; RMSEA = 0.02; RMR = 0.04). The reliability of the social intelligence scale analyzed by Cronbach’s coefficient alpha for each trait ranged from 0.85 – 0.86.
