Assumptions about focus group interviewing were tested. Individual interviews generated more ideas than focus groups, eight-member groups generated significantly more ideas than four-member groups, no differences were found between focus groups and unmoderated discussion groups, and the effect of acquaintanceship was not clearly determined.

Previous research and reviews on comparative advertising report mixed results. The authors report the results from a meta-analysis that examines the efficacy of comparative advertising. The analysis shows that comparative ads are more effective than noncomparative ads in generating attention, message and brand awareness, levels of message processing, favorable sponsored brand attitudes, and increased purchase intentions and purchase behaviors. However, comparative ads evoke lower source believability and a less favorable attitude toward the ad. Additional analyses of moderator variables find that market position (sponsor, comparison, and relative), enhanced credibility, message content, and type of dependent measure (relative versus nonrelative) affect some of the relationships between advertising format and cognition, brand attitudes, and purchase intentions. New brands comparing themselves to established brands appear to benefit most from comparative advertising.

This research adds to the growing body of literature in consumer socialization by examining intergenerational influence on brand preferences and consumption orientations in parents and young-adult offspring. Two factors suggested in past research to affect intergenerational influence are investigated: conformity to peers and communication effectiveness. A new rigorous method is introduced to demonstrate intergenerational similarity in mother/daughter dyads, distinct from an incipient level of similarity that may occur by chance. Results indicate that communication effectiveness is positively related to intergenerational agreement in all six consumption domains studied, whereas daughter's conformity motivation is related only to prestige sensitivity. Implications and directions for future research are discussed.
