This study investigated correlations between the Qualitative score of the Porteus Maze Test and age and rates of recidivism of correctional institution inmates. In addition, the study was structured to provide answers to the following questions: (1) Is there a relationship between age and rates of recidivism and the Conformity-Variability score of the PMT? (2) Is there a relationship between the Qualitative score and the Conformity-Variability score on the PMT? (3) Is the abbreviated method for obtaining the Qualitative score of the PMT a reliabile method? Two sample groups of female inmate subjects were administered the PMT: adult subjects and juvenile subjects. The adult subjects were from a correctional institution in Texas. The juvenile subjects were from correctional institutions in Louisiana and Oklahoma. The study confirmed earlier research concerning the high reliability of the PMT with criminal populations. The study suggested that the records of recidivists and nonrecidivists be followed to ascertain if the subjects who obtained higher Qualitative scores are the ones most likely to be returned to correctional institutions.
