Summary

This study evaluates the efficacy of an intervention based on the Implicit Theories of Personality (ITP) in Spanish adolescents. Half of participants received the ITP intervention, while the other half received an educational intervention.

Conditions

Interventions

BEHAVIORAL

Incremental theory of personality

The experimental intervention (originally developed by David S. Yeager and colleagues) teaches that individuals have the potential to change. It has three main parts. First, participants are asked to read scientific studies that provide evidence that behaviors are controlled by "thoughts and feelings in brains," and that pathways in the brain have the potential to be changed under the right circumstances. Second, participants read several testimonials purportedly written by upperclassmen to bring credibility to the ITP. Finally, participants are asked to write their own version of such a narrative. This self-persuasive writing exercise has been shown to facilitate the internalization of the intervention message, building on a long line of research on cognitive dissonance.

OTHER

Educational Intervention

The educational intervention involved scientific information about the human brain. It was designed to be parallel to the experimental intervention and, hence, it has also three main parts. First, participants are asked to read scientific information about the different areas of the brain and their specialties. Second, participants read several testimonials written by upperclassmen about their transition to high school and how their brains help them to adapt to the new space and all the physical differences of the building and the classes. Finally, participants are asked to write a letter to another student explaining the main things he or she has learned about the brain and thinks are important for adapting to the new physical environment in high school.
