“…Combinations of CPI scales apparently can distinguish among certain kinds of offenders, when they are employed as rudimentary measures of "ego control" (Laufer, Johnson, & Hogan, 1981). Scales from this inventory also have been used to approximate levels of interpersonal maturity (Gottfredson & Ballard, 1963) and social maturity (Gough, 1966) within offender samples. Finally, portions of the CPI have proven to be moderately predictive of parole success (Gough, Wenk, & Rozynko, 1965), assault-proneness (Sarbin,Wenk,& Sherwood,196S), prisoners' grades in educational courses (Steuber, 1975), probationer/parolee employment stability (Gottfredson & Lipstein, 1975), and recidivism (Gendreau, Grant, Leipciger, & Collins, 1979).…”
