Improving the Detection of Personality-Behavior Relationships in Consumer Research

Past suggestions for improving detection of personality-consumer behavior relationships concerned the personality side of the relationship. In contrast, after Epstein (1979, 1980), this research calls for an examination of the reliability of the dependent variable, the behavior measure. Using data from two large-scale lifestyle studies, this research empirically demonstrates how increasing test-retest reliabilities of repeated behavior measures results in enhanced detection of personality-behavior relations. Theoretical and practical implications are discussed.
