Electrodermal responding and chlorpromazine treatment in schizophrenia
S Yannitsi, A Liakos and Y Papakostas
Ioannina University, Greece.
Skin conductance level (SCL) and skin conductance responses (SCR) to a
random series of tones were measured in 25 drug-free schizophrenic
patients, 15 males and 10 female, before and after standard chlorpromazine
treatment. The DSM-III diagnostic criteria were used for selecting
subjects. Psychopathology was measured with the Brief Psychiatric Rating
Scale. After treatment, patients showed an improved psychopathology and
decreased SCL. There was a transition of patients to lower response
categories: the number of responders decreased twice and the number of
non-responders increased three times. Responders exhibited significantly
higher SCL than non-responders and fast habituators were between the two
groups.
