Abstract: Two models about the effect of evidence quality, source expertise, and personal involvement on post-message attitudes were tested with a conceptual replication of Petty, Cacioppo, and GoldmanÂ’s (1981) experiment (N = 386). Evidence quality had a positive effect on both perceived argument quality and perceived source credibility. Source expertise had a positive effect on perceived source credibility. Personal involvement had a negative effect on both perceived argument quality and perceived source credibility. Perceived argument quality had a positive effect on post-message attitudes. The effect of evidence quality and source expertise on attitudes did not differ between high and low personal involvement. The discrepancies in results between the original and the replicated studies were discussed.
