Early parental death: relation to electrodermal orienting response and gender in schizophrenia

The aim of the present study was to examine age at parental loss by death and its relation to electrodermal orienting response and sex in schizophrenia. Forty-four DSM-III schizophrenic inpatients were exposed to a series of moderately intense tones in a standard orienting habituation paradigm, while skin conductance was recorded. The twenty-three patients who failed to respond to any of the first two tones were found to be younger when they lost their first parent compared to the 21 responders. When the 44 patients were divided according to sex, the females were found to be younger than the males when parental loss occurred. Finally, when multivariate analyses were performed, it was found that both responding/nonresponding and sex provided almost equally large independent contribution to the prediction of parental loss.
