6.3. Performance and satisfaction
Confirmatory Factor Analyses were conducted for the multi-item scales measuring the buyer’s perception of supplier performance, the buyer’s satisfaction with the relationship, and the supplier’s satisfaction with the relationship. The scale items retained to measure these constructs are displayed in Table 3, along with the reliability values and fit indices that assess the overall measurement model. All of these remaining scale items display insignificant chi-square values with GFI, CFI and NNFI values in excess of the 0.90 minimums. In addition, all scale items have significant factor loadings p-0.0001 . Together, these values suggest that the scales are unidimensional and display convergent validity. In addition, all scales have Cronbach coefficient alpha values in excess of the 0.60 recommended minimum Cron. bach, 1951; Nunnally, 1978 .
