Apathy in first episode psychosis patients: one year follow up.
BACKGROUND
This study describes how the negative subsyndrome of apathy develops over the first year in first episode psychosis (FEP) patients, with an emphasis on the prevalence of enduring apathy and the relationship between apathy, other symptoms and functioning.


METHODS
Eighty four FEP patients were assessed both at baseline and after one year with the abridged clinical version of the Apathy Evaluation Scale (AES-C-Apathy). Other symptoms were assessed with the Positive and Negative syndrome scale (PANSS) and functioning with the split version of the Global Assessment of Functioning Scale (GAF-F).


RESULTS
The mean level of AES-C-Apathy decreased from baseline to the one year follow up for the whole group of FEP patients. High levels of apathy at 1year were best predicted by high levels of apathy at baseline, a long DUP and a diagnosis within the Schizophrenia spectrum. The presence of depression and level of medication only had a minor influence. AES-C-Apathy had a stronger association to GAF-F than other PANSS symptom areas. Twenty five (30%) FEP patients had high enduring levels of apathy. This group consisted of significantly more males, had a longer duration of untreated psychosis, a greater likelihood of a Schizophrenia spectrum diagnosis, fewer were in remission of positive symptoms and they had significantly poorer functioning at both baseline and follow up.


CONCLUSIONS
This study confirms that the negative subsyndrome of apathy is significantly related to poor functioning in FEP. Including negative symptoms and its subsyndromes in early detection strategies are warranted.
