Reliability and Validity of Conjoint Analysis and Self-Explicated Weights: A Comparison

Abstract
Though the use of conjoint analysis has increased substantially in recent years, relatively little empirical evidence has been published on how its reliability and validity compares with that of alternative methodological approaches. The authors report the results of a study designed to compare the test-retest reliability and predictive validity of several alternative conjoint analysis techniques with that of self-explicated weights under the condition of all attributes being dichotomous. The findings fail to demonstrate greater reliability and validity for the conjoint analysis techniques considered.
