The structual model examined the moderating effects of prior experience in the path
between self congruity and attitude and the path between functional congruity and attitude,
separately. To test the moderating effect in each path, chi-square differences with one degree of
freedom were used to compare the constrained model versus unconstrained model.The
constrained model imposed that the path coefficients of a specific path are equal between groups,
whereas the unconstrained model assumed that the coefficients in each group were not restricted
(Namkung & Jang, 2007). Table 1 shows the results of the specific moderating effects of prior
experience.
For the path between self image congruity and attitude, the chi-square difference was not
significant (χ2 = .043, P>.05), indicating that prior experience has no moderating effect on the
relationship between self image congruity and attitude toward a brand coffee shop.
On the other hand, prior experience exhibited a moderating effect on the relationship between
functional congruity and attitude toward the brand coffee shop (Δχ²(Δdf=1)= 4.281, P
