Character-Audience Racial Matching, Prescription Opioid Misuse Experience, and the Effectiveness of Anti-Prescription Opioid Messages: The Mediating Roles of Identification and Perceived Severity.

An online experiment was conducted among a convenience sample of non-Hispanic young Black and White Americans to test the impact of character-audience racial matching on intentions to avoid (mis)using prescription opioids while considering the mediating roles of identification and perceived severity and the moderating role of prescription opioid misuse experience. It found that the racial matching had a positive overall impact on the behavioral intentions. The impact was partly explained by three pathways: 1) identification, 2) perceived severity, and 3) the sequential pathway of identification and perceived severity. It also found that prescription opioid misuse experience moderated the impact of the racial matching on identification. As a result, the racial matching was found to influence the behavioral intentions of participants with different prescription opioid misuse experience via somewhat different routes. These findings have a number of theoretical and practical implications.
