[Anhedonia and sensation seeking].

The relationship between anhedonia and sensation seeking has been studied in 56 normal subjects of both sexes (33 males, 23 females). Anhedonia and sensation seeking were respectively defined by two reliable rating scales: Physical Anhedonia Scale of Chapman (PAS), Zuckerman's Sensation Seeking Scale (SS form V -40 items). The results have shown a negative correlation between this scales for males but not for females. These finding suggest that lowered levels of sensation seeking could constitute for males, like anhedonia, a risk factor of schizophrenia.
