Facial affect recognition in the course of schizophrenia.
Deficits in facial affect recognition have been shown repeatedly in schizophrenia. However, the stability of this deficit over time remains to be clarified. A total of 36 remitted, 32 acutely ill schizophrenic patients and 21 healthy volunteers participated in a cross-sectional and longitudinal study. All subjects were assessed twice within 4 weeks (acute schizophrenics and normal controls), or 12 weeks, respectively (remitted schizophrenics). Subjects had to identify six basic emotions from corresponding facial expressions shown as photographs on a video screen. Both acute and remitted schizophrenics demonstrated a stable deficit over time in facial affect recognition unrelated to psychopathology and medication. This suggests that deficits in facial affect recognition in schizophrenia reflect a trait-like, rather than a state-dependent, characteristic.
