Previous research has shown that the female
Pharmacist scale on the Strong-Campbell Interest
Inventory (SCII) was more valid than the male
Pharmacist scale for both male and female college
students. The female scale was not as valid for men
as it was for women, however, because of the sex
differences reflected in its item content. In an
attempt to develop a "unisex" occupational scale
which would be equally effective for men and
women, all items which differentiated between
males and females by 10 percentage points or more
were eliminated from the female scale. The remaining
items (20 of 39 original items) formed a
short unisex scale that was nearly as reliable and
valid as the original scale over short time periods.
The unisex version did not require separate norms
or different interpretations of the scores for men
and women. The possibility of constructing an
abbreviated form of the SCII that contains only
sex-balanced items merits further consideration.
