There are also six supplementary scales (e.g., Immaturity Scale, Anxiety, Repression) and additional newly developed content scales (e.g., A-dep/Adolescent -Depression).
To counter c la irns that the MMPI is too long, espe- cially for adolescents, the new _MMPI-A contains 478 j t e rns , thereby shortening the ad- rnini s tr at ion t irne, This can be shortened even further by administering only the first 350 iterns , still sufficient to obtain the validity and standard clinical scales. Thus, theMMPI-A is both strongly related to the MMPI and MMPI-2 (and their respective data- bases) but also has a number of important distinctive features of its own.
