This study compares empirically the construct validity of both approaches. The results indicate that the reliability, the content validity, the within-method and across-method convergent validity, and the discriminant validity of both approaches are acceptable. While the a priori dimensionality of the direct approach was recovered, a dimension not hypothesized was found for the indirect approach to power source measurement. Because the direct power source measures were significantly related to the attributions of power while the indirect ones were not, the direct approach demonstrated better nomological validity. We were not, however, able to assess the impact of shared methods variance upon the validity of these measurement approaches. Overall, the direct approach to measuring the sources of marketing channel power appears to have greater construct validity.10aMarketing1 aBrown, James, R.1 aJohnson, Jean, L.1 aKoenig, Hal  u/biblio/measuring-sources-marketing-channel-power-comparison-alternative-approaches-000569nas a2200133   4500008004100000245010000041210006900141260002000210653001400230100001600244700002000260700002100280856013400301       1987                        eng d00aAssessing Unidimensionality, Discriminant and Convergent Validity:  A New Approach in Marketing0 aAssessing Unidimensionality Discriminant and Convergent Validity  aMiami, FLc198710aMarketing1 aKoenig, Hal1 aHampton, Ronald1 aBrown, James, R.  u/biblio/assessing-unidimensionality-discriminant-and-convergent-validity-new-approach-marketing-000583nas a2200133   4500008004100000245010600041210006900147260002700216653001400243100001600257700002200273700002100295856013300316       1985                        eng d00aThe Bases of Marketing Channel Power:  An Exploration and Confirmation of Their Underlying Dimensions0 aBases of Marketing Channel Power An Exploration and Confirmation  aWashington, D.C.c198510aMarketing1 aKoenig, Hal1 aJohnson, Jean, L.1 aBrown, James, R.  u/biblio/bases-marketing-channel-power-exploration-and-confirmation-their-underlying-dimensions-100534nas a2200133   4500008004100000245008100041210006900122260002200191653001400213100001600227700002600243700002100269856011000290       1984                        eng d00aThe Bases of Power:  Their Effect Upon Retailer's Perceptions of Uncertainty0 aBases of Power Their Effect Upon Retailers Perceptions of Uncert  aChicago, ILc198410aMarketing1 aKoenig, Hal1 aKroeten, Terrence, T.1 aBrown, James, R.  u/biblio/bases-power-their-effect-upon-retailers-perceptions-uncertainty-1
