This study assessed the quality of the measurement models by investigating unidimensionality, composite reliability, estimates of variance extracted, convergent validity, and discriminant validity. Table 4 shows that the overall goodness of fit supports undimensionality (Steenkamp & van Trijp, 1991). Unidimensionality tests were performed on all of the constructs by examining the estimated loadings and assessments of their statistical significance on each construct. An inspection of factor loadings showed that all items had significant factor loadings, with t values exceeding 1.96. All of the constructs had alpha coefficients greater than .7.
