This study focuses on analysis of the factors that can increase the persuasive effectiveness of information campaigns using narratives.An experiment was carried out in which similarity with the protagonist was manipulated in a video about a victim of gender violence.The protagonist was portrayed as living in Spain, and she was said to be Spanish (high similarity) or Argentinian (low similarity).The participants (75 Spanish women) then filled out a questionnaire with measures about emotional impact, identification with the protagonist, and risk perception about becoming a victim of abuse.Results showed that similarity with the protagonist has an indirect influence on risk perception through negative emotions and identification.
