A comparison of professionally employed lesbians and heterosexual women on the MMPI.

The hypothesis tested is whether lesbianism implies psychopathology. The MMPI was given to 26 nonpatient lesbians who were professionally employed full time, and the results were compared to those for a group of 29 similarly employed heterosexual women. With the exception of the Sc scale, no difference was found on the clinical scales. The lesbian group achieved a significantly higher elevation than the nonlesbians on the Mf and Sc scales. Further analysis of the data on the Sc subscales indicated no difference on the pathological part of the scale, but rather a difference in degree of social alienation. Analysis of the data according to a second variable, living status, found significant differences and has important implications for future studies of the lesbian population. Single women, regardless of sexual orientation, scored significantly higher on scales K and Pa and on the Pa subscale naivete. A significant interaction between sexual orientation and living status was achieved on one scale, the F scale.
