The ‘Peter Pan Syndrome’ affects people who do not want or feel unable to grow up, people with the body of an adult but the mind of a child. They don’t know how to or don’t want to stop being children and start being mothers or fathers.
The syndrome is not currently considered a psychopathology, given the World Health Organization has not recognized it as a psychological disorder. However, an increasingly larger number of adults are presenting emotionally immature behaviors in Western society. They are unable to grow up and take on adult responsibilities, and even dress up and enjoy themselves as teenagers when they are over 30 years old.
Humbelina Robles Ortega, professor of the Department of Personality, Evaluation and Psychological Treatment of the University of Granada and an expert in emotional disorders, warns that the overprotection of parents can lead children to develop the Peter Pan Syndrome, given “it usually affects dependent people who have been overprotected by their families and haven’t developed the necessary skills to confront life.” The ‘Peter Pans’ of present society “see the adult world as very problematic and glorify adolescence, which is why they want to stay in that state of privilege.”
