Confirmatory factor analysis
Guided by the results of EFA and to confirm the above results, we conduct a
confirmatory factor analysis (CFA) by specifying a measurement model. In line with
Hair et al. (2010, p. 644), model fit was assessed using χ2 values and degrees of
freedom, the CFI and the RMSEA. The initial model fit for the measurement model
including all the 23 items of organizational culture showed unreasonable fit: CMIN/
DF¼2.910; CFI¼0.888; RMSEA¼0.075. Therefore the model was modified and four
items namely OC.EmpDev.1, OC.Harmony.1, OC.CustOrient.4 and OC.SocRes.1 were
dropped. As Table III below shows, after removing these items from the measurement
model, the new model fitted the data better: CMIN/DF¼2.571; CFI¼0.931;
RMSEA¼0.068.
