The original (Wirt, Lachar, Klinedinst, & Seat, 1977) and shortened scales (Lachar, 1982) of the Personality Inventory for Children (PIC) were compared in a sample of 230 clinic children. The short versions of the ADJ and SSK scales produced significantly lower T scores than the original version, while the short version of ACH, D, FAM, ANX, and HPR produced higher scores. Mean differences were small and never exceeded 3 T score points. Scales were classified by use of a T >69 criterion or the actuarial criteria of Lachar and Gdowski (1979). The percentage of identical classifications ranged from 87% to 97% with the T >69 criterion and 92% to 99% with the Lachar and Gdowski criteria.
