Lack of population validity

• Why might research on media and addiction lack population validity?

  • many studies focus on adolescents, who are more susceptible to social influences, so results may not apply to adults
• What did Jamieson & Romer (2015) find about media influence on adult smoking?

  • they found a correlation between tobacco use in TV shows and smoking rates in the US, suggesting media may also influence adults or trigger relapses
