The Development of the Transformational Leadership Measurement Model of Employees in the Retail Business
The objective of this research was to study transformational leadership measurement model. The samples were 452 employees in the retail business in Thailand. The instrument used in this research was variables of transformational leadership questionnaire divided into 4 elements: Charisma, Inspirational motivation, Intellectual stimulation, and Individualized consideration. The questionnaire consisting of 43 items was examined its content validity by 3 scholars. Discrimination power was determined using corrected item–total correlation. It was found that the discrimination power was between .578 and .889. Overall reliability was also determined using measure of internal consistency analyzed from Cronbach’s coefficient alpha. It was found that the overall reliability was .984. According to the second-order confirmatory factor analysis, p–value of 2 .05, GFI .90, AGFI .90, NFI .90, SRMR.05, 2/df 2, RMSEA .05, CFI .90, and CN 200 were used to evaluate consistency of the results of this research. The results revealed that p–value of 2 = .052, GFI = 0.932, AGFI = 0.901, NFI = 0.996, SRMR = 0.018, 2/df = 1.092, RMSEA = 0.014, CFI = 1.00, and CN = 451.918. Therefore, the results were consistent with empirical data. Furthermore, construct reliability of overall transformational leadership was 0.9914 and its 4 elements which were Charisma, Inspirational motivation, Intellectual stimulation, and Individualized consideration were 0.9682, 0.9561, 0.9794, and 0.9582, respectively.
