Validity of the MMPI-2 basic and Harris-Lingoes subscales in a forensic sample

The present study explored the MMPI-2 correlates of criminal history in a sample of prison inmates. Although Ma was the only basic scale to demonstrate a significant positive association to crime history, three Harris-Lingoes subscales also bore significant associations to this criterion. The Ma1 (amorality), Pd2 (authority problems), and Pd5 (self-alienation) subscales demonstrated positive associations with crime history. Hierarchical multiple-regression analyses were used to examine the incremental validity of the D, Pd, and Ma Harris-Lingoes subscales when added to their parent scales in the prediction of crime history. Only the Pd Harris-Lingoes subscales demonstrated incremental validity in the prediction of this criterion. The value of including the Ma and Pd Harris-Lingoes subscales in criminal risk assessment is discussed.
