To assess the frequency of affective and psychotic symptoms in athletes
taking anabolic steroids, the authors performed structured interviews of 41
body-builders and football players who had used steroids. According to
DSM-III-R, nine subjects (22%) displayed a full affective syndrome, and
five (12%) displayed psychotic symptoms in association with steroid use.
These findings suggest that major psychiatric symptoms may be a common
adverse effect of these drugs.
