Individuals who have experienced consistent invalidation throughout their lives may struggle with low self-esteem and a fear of rejection. As a coping mechanism, they may exhibit high Peter Pan syndrome, avoiding adult responsibilities and seeking validation and comfort through childlike behaviors. By refusing to grow up, they can escape the demands and potential rejections of adulthood, perhaps resorting to a false sense of safety and control in their lives.

In contrast, individuals who have received significant validation and support in their formative years may develop a healthier sense of self-worth and self-efficacy, as shown above in our study. They are more likely to transition into adulthood, take on responsibilities, and face challenges head-on. This is evidenced by the reverse relationship between Peter-pan syndrome and invalidation experience. Invalidation, when present, may still affect them but to a lesser extent, as their foundation of validation provides a counterbalance to cope with the invalidating experiences.

Invalidation can disrupt an individual's belief in a just world. When someone consistently experiences invalidation, their emotions, and efforts are treated as insignificant by others.  Their personal experience of unjust treatment will negatively reflect on their vision of the whole world as being morally unfair. Consequently, it will cause them to challenge their perception of fairness in the world. The perception of the world as being unfair, will not only harm their personal relationships but also limit their involvement in society as a whole.
