The purpose of the present study was to determine whether or not significant correlations could be obtained between raw scores on fifty-three scales of the Mini-Mult Prison Questionnaire (MMPQ), a personality test, and nine selected behavior variables for a group of thirty-two institutionalized male delinquents. A correlation matrix using Pearson's r revealed that seven MMPQ scales correlated at the p = .05 level of significance with the behavior criteria. Thus, four of the five hypotheses formulated were supported. However, caution was emphasized in interpreting the results due to sample size, sample homogeneity, and the dissimilarity of the adolescent sample from the adult prison population on which the MMPQ was developed.
