MMPI-2 profiles of Lakehead University students / Elizabeth M.R.M. Lettner.

Until most recently university students were considered to
\nscore significantly higher on the MMPI clinical and validity
\nscales, in terms of their mean profiles, than the original
\nnormative non-psychiatric sample. According to the only study
\nby Butcher, Graham, Dahlstrom and Bowman (1990) on this
\nsubject, this does not seem to be the case on the MMPI-2.
\nThe present research was a study of the same type as the
\nButcher, Graham, et al. (1990) study but with a Canadian
\nsample of university students, at Lakehead University in
\nThunder Bay. The results obtained from the present study
\nshowed significant elevations in terms of the mean profiles
\nfor both male and female students on several of the validity
\nand clinical scales of the MMPI-2 in comparison to the
\nnormative sample. The obtained differences may reflect the
\nyounger age, as well as the socio-economic differences of the
\nLakehead University sample compared to the MMPI-2 normative
\ngroup. Results also revealed that the L.U. student sample
\nresponded, as a group, in a manner similar to the Butcher,
\nGraham, et al. (1990) university student sample. Similar mean
\nscores were obtained with only very few significant
\ndifferences. The group profiles were also compared between
\nthese two student samples and displayed a considerable degree
\nof similarity. It is unclear whether the apparent contradictions between the results of the present study and
\nthe Butcher, Graham, et al. (1990) study reflect real
\ndifferences of statistical and clinical significance, or
\nwhether they are the result of too small samples, or the
\ndifferent statistical methods and criteria. However, if these
\nresults reflect real differences and not statistical errors,
\nthis would suggest that, contrary to the Butcher, Graham, et
\nal. (1990) conclusion, the MMPI-2 norms might not be
\nappropriate for use with college students.
