Research has come to distinguish three main subtypes of the personal fable. Omnipotence relates to the adolescent believing he has great authority or power (i.e. he is capable of what most others are not). Invulnerability is just that: the adolescent believes he cannot be harmed or affected in the ways others can. And finally, uniqueness is the adolescent's belief that he and his experiences are novel and unique to him (i.e. no one else could possibly relate). Distinguishing between the personal fable's three subtypes has merit. Research has shown that omnipotence does not seem to be related to delinquent behaviour such as substance use, nor to depression or suicidal ideation. In fact, omnipotence is suggested to act as a protective factor, allowing for superior adjustment, high coping skills and self-worth. Contrary to omnipotence, invulnerability relates to risk behaviour and delinquency, and uniqueness, which is more prevalent in girls, is related to depression and suicidal ideation (and is found to increase with age). Research has focused significantly more on the personal fable's negative effects and it is important to consider pursuing omnipotence to capitalize on its positive results.
