Anxiety and menstrual bleeding in Nigerian females.

This paper reports on a study which examined the relationship between menstrual bleeding and anxiety as a multidimensional concept. Anxiety was measured using a standardized psychological instrument, the STAI. It was hypothesized that (1) state anxiety was raised during menstruation and (2) the amount of increase in state anxiety during menstruation depended on the level of trait anxiety in a given female. These hypotheses were confirmed. It was also found that the experimental group scored higher than the control group on both positive and negative items, which may be an indication that the former exaggerated their symptoms.
