Overcoming adolescents' resistance to anti-inhalant appeals.

This research was concerned with factors that affect adolescents' evaluations of persuasive anti-inhalant messages and the association of these evaluations with usage intentions. Sixth and 7th graders (N=894) received anti-inhalant messages that varied as a result of the factorial combination of message source (doctor or peer), suggested harm (social or physical), and target (message was addressed directly or indirectly to receivers). Manipulated variables were crossed with inhalant-user status (resolute nonuser, vulnerable nonuser, and user). Significant (p<.01) target and status effects on message evaluation were found. Significant interactions of status with each of the manipulated variables also emerged. Users were resistant to threatened physical harms, but suggested harms did not differentially affect resolute nonusers or vulnerable nonusers. Users and vulnerable nonusers evaluated the message more positively when targeted indirectly (p<.05). Vulnerable nonusers were more receptive to peer sources, whereas users preferred adult sources. Message evaluation was significantly associated with inhalant usage intentions (r=-.22), and this association held even after the contributions of sex, sensation seeking, acculturation, prior use, familism, and assumed peer usage were accounted for in a multiple regression analysis (overall R(2)=.24).
