Abstract
This study evaluated whether psychiatric outpatients with a past stimulant use disorder in full remission for >/= 2 months (STIM+, n = 204) and those with no history of stimulant use disorder (STIM-, n = 2070) differed in the prevalence of current anhedonia and amotivation. Results showed that a significantly greater proportion of STIM+ participants reported anhedonia and amotivation than STIM- participants. The relation between stimulant use disorder history and anhedonia remained robust after controlling for other relevant clinical and demographic factors. These findings suggest that anhedonia may be a preexisting risk factor or protracted effect of stimulant misuse.
