Hans Villarica’s article about dealing with peer aggression describes a fascinating example of how a growth mindset, or believing that success comes from effort, can help with social relationships as well as individual abilities.
While I strongly object to the title suggesting this approach is to “fix the victims,” I do agree with the value of encouraging everyone involved to develop productive coping strategies, and the article describes compelling research demonstrating the power of believing that relationships can be repaired. According to the article’s summary of a study surveying 373 second-graders:
those who were genuinely interested in fostering friendships tended to react in healthful, positive ways. They asked their teacher for advice, sought emotional support, and found means to solve the tension with those who harassed them.
Further, a previous study surveying 206 elementary-school children revealed that those with an incremental theory of peer relationships were more resilient to peer victimization. As summarized in the article:
Children who believed friendships are fixed, succeeding or failing without their involvement, tended to be more enamored with popularity and may be more vengeful as a result. On the contrary, those who viewed their friendships as works in progress tended to appreciate their peers more and interact more responsibly. ‘If children believe that effort is worthwhile, they’ll feel less threatened or helpless when they hit bumps in their relationship,” [psychology professor Karen D. Rudolph] says, ‘and they’ll be more likely to try to resolve relationship problems.
Conclusion: Believing that social relations can be repaired is worth the effort.
Now I just need to find out if someone has applied this approach to attachment theory.
