title: Applicability of the Group Personality Projective Test within a prison population.
abstract: Administered the Group Personality Projective Test (GPPT) to 60 male offenders incarcerated in a state penitentiary. A board of 10 prisoners selected inmates who clearly had demonstrated one of three patterns of assaultive behavior: undercontrolled aggressives, overcontrolled aggressives, and over controlled psychopaths. A control group was chosen randomly from the prison population, as well. Results failed to support the hypothesis that GPPT scores significantly differ among relatively homogeneous prisoner subgroups or between these groups and the control group of non-assaultive prisoners.
