Organizational Commitment Survey: A Confirmatory Factorial Analysis Based on Vocational Colleges Teachers Sample

Abstract

This study was conducted to verify the construct model for organizational commitment among technical teachers at the Vocational College under the Ministry of Education. A study involving 25 vocational colleges with a total sample of 493 people consisting of teachers in mechanical engineering, electrical and electronic engineering fields, and engineering. This study uses Structural Equation Modeling (SEM) approach with AMOS 20 software. Researchers used the Organizational Commitment Questionnaire (OCQ) developed by Meyer, Allen, and Smith (1993) and Meyer and Allen (1997), comprising three substructures namely affective commitment, normative commitment and continuous commitment. The number of items is 24, 8 items per sub construct and after exploratory factor analysis is carried out there were only 22 items left. In order to ensure that the organization's commitment measuring model is verified, three factors have been evaluated as unidimensionality (looking at the factor loading ≥ 0.6), Validity (convergent validity AVE ≥ 0.5, and construct validity refers to fitness indexes) and Reliability (composite reliability, CR ≥ 0.6 and Average Variance Extracted ≥ 0.5). After the CFA analysis is carried out no items were dropped because all items have loading factors> 0.6, AVE ≥ 0.5 values for all sub constructs. While fitness indexes for Absolute Fit (RMESA = 0.062), Incremental Fit (CFI = 0.953, TLI = 0.945) and Parsimonious Fit (Chisq/df = 2.918) met the requirements set for all CR values ≥ 0.6. It can be concluded that after the measurement model was modified by looping between items, the model was fit to be used for structural model analysis process.
