Specificity of psychoanalytic hypotheses regarding the onset of adolescent psychoses: an empirical test of a psychodynamic model.

The specificity of psychodynamic hypotheses regarding the onset of adolescent psychosis was assessed in a group of rigorously diagnosed psychotic (N = 75) and depressed (N = 53) adolescents. None of the four operationally defined psychodynamic hypotheses purported to be etiologically specific in the onset of adolescent psychotic illness: success and its opportunities; intimacy and its attempts; intent to act autonomously; or involved in insight-oriented psychotherapy was more commonly observed in the psychotic than the depressed group, thereby not supporting the hypotheses. The consequences of this finding are discussed.
