The Influence of Flooding Imagery and Party Cues on Perceived Threat, Collective Efficacy, and Intentions for Political Action to Address Climate Change

This study investigates how episodic and thematic flooding imagery and political party cues in climate change news stories influence risk perceptions, collective efficacy perceptions, and intended political action. We found that imagery and party cues had significant total effects on perceived flooding threat but not on perceived climate change threat. Specifically, episodic imagery (but not thematic imagery) increased perceived flooding threat, and party cues lowered perceived threat. Perceived threat was positively associated with collective efficacy, which, in turn, was positively associated with intended political action. Both imagery and party cues had significant indirect effects on perceived efficacy and intended action.
