Identity development in adolescence may act as stressor triggering juv
enile psychotic episodes. A model is being presented stating that self
development in subjects with high vulnerability for psychosis leads t
o the establishment of an ''imaginary self'' consisting of phantasies
and fictions without taking into account facts a nd social realities.
The ''imaginary self'' stabilizes irritating self deficiencies, thus l
eading to a vulnerability for depersonalisation and identity diffusion
during actual turmoils of adaptation.
