Abstract
108 undergraduates rated the degree of mental illness of 10 case descriptions on a 5-point scale. Two forms were used, matched for the 10 case problems but varied for case sex. Analysis of variance yielded significant main effects for sex of the respondent and case sex. Male respondents attributed more mental illness than female respondents to the cases. The mean rating of case sex for male items was significantly higher than female items. However, 6 of the 7 items which varied sex between forms failed to differ significantly using t tests.
