Abstract
BackgroundSpeed of processing is a cognitive process underlying cognitive
dysfunction in people with chronic schizophreniaAimsTo investigate the contribution of speed of processing to the cognitive
deficits observed in a representative large sample with first-episode
schizophreniaMethodPeople with a diagnosis of first-episode schizophrenia-spectrum disorders
(n=26) and healthy controls (n=28)
were compared on several cognitive measures before and after controlling
for speed of processingResultsBefore controlling for speed of processing, patients and controls
differed significantly on all cognitive measures. All significant
differences in cognitive functioning disappeared when the result of the
Digital Symbol Substitution Test was included as an additional
covariateConclusionsSpeed of information processing may be considered a core cognitive
deficit in schizophrenia and might be mediating a broader diversity of
cognitive disturbances
