The purpose of this study was to find out the correlation between the theoretical model of the organization’s capability contribution, participation, and the climate of change to the commit-ment to change. Subjects were Islamic University lecturers in Indonesia who experienced the organizational change. Findings reveal (a) the theoretical model designed in this study fitted the empirical data; (b) the determination coefficient (R2) of the commitment to change was 15.1%, which showed that 15.1% of the commitment to change can be explained or predicted through the organization’s capability, participation, the climate of change and the open-mindedness to changes variables; (c) the model was acceptable based on the fit model test with 60.785 chi-square value and .275 (> .05) probability, the CFI value was .997 (almost 1), and the RMSEA value was .022 (< .08). This study has found out the determining theoretical model of the commitment to change based on the organization’s capability, participation, the climate of change, and the open-mindedness to changes’ roles in establishing the commitment to change. The open-mindedness to changes as a mediator is significant, because without the mediator, the organization’s capability, participation, and the climate of change have no effects to the commitment to change.
