One thousand one hundred and twenty-three Japanese male and female University students were asked to name and rate the intensity of three situations that made them anxious. Correlations between frequency of occurrence and rated intensity for situations named more than once were negligible for both sexes. The intensity rating of 72 situations occurring in common between the sexes was significantly greater for females but there was no difference in the frequency of occurrence. Correlations between male and female frequency and male and female intensity were positive and significant for the shared items, indicating that their experiences of these anxiety situations vary in similar ways. Three types of anxiety threat situations were also analyzed: interpersonal-ego threat, physical threat and ambiguous threat.
