The subjects were 165 incarcerated female felons who were residing or had resided in a minimum security women's reformatory in Iowa during 1960-1974, and who had completed the MMPI as part of an admissions inventory within 2 weeks of entrance to the reformatory. The first 168 items of the regular MMPI were scored by the regular scoring keys, and the raw scale scores were then converted to estimates of full MMPI scale scores through the use of a conversion table. The results indicated a high degree of agreement between corresponding validity and clinical scales of the MMPI-168 and the full MMPI. The MMPI-168 significantly overestimated scales L, F, and D, while it underestimated scales K, Hy, Pd, and Mf. Configural correspondence between the two instruments in terms of profile high points was somewhat less than has been reported for psychiatric populations. However, the MMPI-168 appeared to be a useful short screening instrument for incarcerated female felons with respect to accurate assessment of profile validity, configural correspondence to the full MMPI, and correlations between corresponding scales. Its utility in these respects far exceeds prior attempts to employ the Mini-Mult -- another shortened version of the MMPI -with a similar sample of incarcerated females. However, the generalizability of the present MMPI-168 findings to other samples of adult female felons in other settings remains to be investigated. Twenty-three references are provided.
