Casual Factor Model Affecting Organizational Commitment of Staff Members of Rajabhat Universities in Northeast of Thailand

Abstract

The purposes of this research were (1) to analyze the confirmatory factors of organizational commitment, quality of work life, leadership, and organizational culture of staff members of northeastern Thailand's Rajabhat universities (NTRU staff) and then verify the structural equation model; (2) to estimate the sizes of the direct, indirect, and total effects of causal factors that affect the organizational commitment of the NTRU staff. The samples were 320 staff members selected by stratified random sampling from all the Rajabhat universities in the Northeast of Thailand. A questionnaire of five-Likert type rating scales (with IOC =0.80-1.00, discrimination power (r) = 0.616-1.132, validity co-efficient = 0.880-0.964) was used to collect the data. The results were as follows: 1)the analysis of confirmatory factors pertaining to organizational commitment, quality of work life, leadership, and organizational culture of members of staff of Rajabhat universities in Northeast of Thailand revealed that the loadings of all the latent factors were statistically significant at the 0.05 level and that the proposed model was fitted with the empirical data, based on the pertinent indices (χ2 = 224.0742, df = 82, χ2 /df = 2.740, RMSEA = 0.074, CFI = 0.972, TLI = 0.959, SRMR = 0.035); 2) the latent factor directly affecting organizational commitment was quality of work life; while the latent factors with total effects included organizational culture, quality of work life, and leadership, respectively, also at the 0.05 statistical significance level. All the factors within the model could explain 44.90 percent of the variance of the latent variable of organizational commitment.
