Abstract

Background: 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.

Method: 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.

Results: Both positive and negative symptoms were associated with physical anhedonia. A positive association between physical anhedonia and the non-paranoid sub-category of schizophrenia was also proved.

Conclusion: According to these results, it seems that in the acute phase of schizophrenia, physical anhedonia may be a contributing factor to patient's psychopathology.
