Self-other differentiation among psychotic and conduct-disordered adolescents as measured by human figure drawings.

24 psychotic-spectrum adolescents were compared with 23 conduct-disordered adolescents on a self-other drawing differentiation task. Of the 24 psychotic-spectrum disordered adolescents, 14 received the diagnosis of Psychotic Disorder NOS (Group 1) and the remaining 10 had diagnoses of Schizophrenia, Bipolar Disorder with Psychotic Features, and Schizoaffective Disorder (Group 2). Interestingly, less impaired adolescents (Groups 1 and 3, the conduct-disordered group) showed significantly more difficulty than the more impaired adolescents (Group 2) on self-other differentiation as measured by their differentiated drawings.
