Coffee consumption among psychiatric inpatients
DK Winstead
Of 135 patients on an acute psychiatric ward, 34 were "high users" of
coffee. The high users tended to be older, single, and have diagnoses of
psychosis. They showed significantly more state anxiety than other
patients, but there were no differences in trait anxiety or MMPI scores.
Further research is suggested to determine whether high caffeine
consumption among inpatients may be related to staff coffee- drinking
behavior and/or treatment with anticholinergic drugs.
