Longitudinal post-validation of the MMPI Escape (EC) and Prison Adjustment (AP) scales

Conducted a longitudinal 3-year post-validation study of the MMPI Escape (Ec) and Prison Adjustment (Ap) scale score of 301 male felon inmates convicted of major type crimes and serving sentences of 5 years or more within the North Carolina Correctional System. Examination of the escape and infraction records of these inmates in relationship to their Ec and Ap scale scores demonstrated that the two scales were still effective classification instruments in predicting escape from within prison units that provided inner and perimeter security and in predicting the committing of major rule infractions irrespective of the degree of custodial control. Caution was expressed concerning the use of the Ec and Ap scale scores without supportive date from their classification procedures.
