The relationship of personality style to abstract thinking deficits in schizophrenia

Hypothesized that the correlation between Inability to Abstract and Autism measures of schizophrenics would be larger after the effects of relevant personality variables were partialed out than before. The multiple correlations of these deficit measures with 15 of the Sixteen Personality Factor scales and a measure of verbosity were determined in a sample of 100 schizophrenics. The correlations between Inability to Abstract and Autism before and after those scales that contributed significantly to the Rs had been partialed out also were calculated. Neither was significant. The results offer no support for the view that observed differences between schizophrenic subgroups in inability to abstract and autism reflect variations in personality style rather than cognitive factors.
