Having obtained estimates for the loadings and error
variances for the interaction terms, two nested models were
then specified. In both models, the loadings and error variances
for the interaction terms were fixed at their previously
estimated values. The first model was a restricted model in
which the γ parameters linking the ‘formalization–environment’,
the ‘centralization–environment’, and the ‘coordination–
environment’ interaction terms to EMO behavior were
fixed at zero, and the remaining γ parameters were freely
estimated. The second model was an unrestricted model in
which those γ parameters originally fixed at zero were freed.
As is shown in Table 1, moving from the restricted model to
the unrestricted model resulted in a decrease in χ2 of 2.84, with
an associated decrease of 3 degrees of freedom. Although this
is an improvement in fit, it is not significant at p
