Eco-innovation models 243
Construct validity of process eco-innovation model
All measurement items and values of Cronbach’s alpha are reported in
Table 84. Content validity for the survey instrument is supported by the
literature, in-depth interviews with environmental managers and a pi-
lot test. A Confirmatory Factor Analysis (CFA) model using EQS 6.1
is estimated to assess the construct validity. In the model, each item is
linked to its corresponding construct with freely estimated covariance.
The model fit indexes are as follows: Chi-square = 1475.364; df = 879;
NFI = 0.818; NNFI = 0.906; CFI = 0.916; RMSEA = 0.060; SRMR =
0.060, which suggests that the measurement model is acceptable. In addi-
tion, the Cronbach’s alpha is 0.939, while the reliability coefficient RHO
is 0.978.
