title: Short-form Philadelphia naming test: rationale and empirical evaluation.
abstract: OBJECTIVE
  To create two matched short forms of the Philadelphia Naming Test (PNT; Roach, Schwartz, Martin, Grewal, & Brecher, 1996) that yield similar results to the PNT for measuring anomia.
  
  
  METHODS
  In Study 1, archived naming data from 94 individuals with aphasia were used to identify which PNT items should be included in the short forms. The 2 constructed sets of 30 items, PNT30-A and PNT30-B, were validated using archived data from a separate group of 56 individuals with aphasia. In Study 2, the reliability of the PNT, PNT30-A, and PNT30-B across independent test administrations was evaluated with a new group of 25 individuals with aphasia who were selected to represent the full range of naming impairment.
  
  
  RESULTS
  In Study 1, PNT30-A and PNT30-B were found to be internally consistent, and accuracy scores on these subsets of items were highly correlated with the full PNT. In Study 2, PNT accuracy was extremely reliable over the span of 1 week, and independent administrations of PNT30-A and PNT30-B produced similar results to the PNT and to each other.
  
  
  CONCLUSIONS
  The short forms of the PNT can be used to reliably estimate PNT performance, and the results can be compared to the provided norms. The 2 matched tests allow for the measurement of change in an individual's naming ability.
