The aim of the current study is to investigate the relationship between physical anhedonia and psychopathological parameters, pharmacological parameters or motor side-effects in a sample of inpatients with schizophrenia in an acute episode of their illness.
Eighty one patients with schizophrenia, consecutively admitted, with an acute episode of their illness, at the Eginition Hospital, Department of Psychiatry, University of Athens, during a one-year period were investigated regarding possible relationships between physical anhedonia, social-demographic data and clinical parameters as well as motor side-effects, induced by antipsychotic agents. All patients were assessed using the Chapman Revised Physical Anhedonia Scale (RPAS), the Positive and Negative Syndrome Scale (PANSS), the Rating Scale for Extrapyramidal Side-Effects (EPSE), the Barnes Akathisia Rating Scale (BARS) and the Abnormal Involuntary Movement Scale (AIMS). Simple cross tabulations were initially employed. Subsequently, multiple regression analysis was performed.
