This investigation examined antecedents associated with support for clean indoor air policies. Participants (N = 550) living in a Midwestern county (population = 62,223) were randomly sampled. Results suggest that beliefs in the health risks associated with secondhand smoke are positively associated with favorable attitudes toward clean indoor air policies, whereas trait reactance is negatively associated with these attitudes. Findings also indicate that risks and trait reactance are indirectly associated with support for clean indoor air policies, mediated through anger arousal toward exposure to secondhand smoke. In addition, regression analyses revealed that health risks, trait reactance, and smoking status explained a significant amount of variance regarding anger toward exposure to secondhand smoke, but only health risks and smoking status accounted for a significant amount of variance toward clean indoor air attitudes. Finally, the Smoking Status x Health Risks interaction was supported for anger toward exposure to secondhand smoke and favorable attitudes toward clean indoor air policies. Our findings suggest the incorporation of anger appeals when promoting clean indoor air policies.
