Electrodermal activity as a predictor of social functioning in female schizophrenics.
Twenty-nine female schizophrenics and 20 female controls were presented with a series of moderately intense tones in a standard orienting habituation paradigm while skin conductance was monitored. Premorbid adjustment and symptoms were also rated, and the schizophrenics were observed 2 years later. The total schizophrenic group was divided into a good-outcome group and a poor-outcome group. Good social functioning outcome required both self-supporting ability in the job market and at least a minimal social life. The poor-outcome group had a significantly higher skin-conductance level and frequency of spontaneous skin-conductance fluctuations than the control group, whereas the few patients with good outcome did not differ from controls. These results are contrary to previous findings with a group of schizophrenic men in which poor social functioning was associated with low electrodermal activity. This discrepancy is discussed in terms of sex differences in schizophrenic disorder.
