Investigating the interchangeability and diagnostic utility of the PPVT-III and PPVT-IV for children with and without SLI.

The receptive vocabulary performance of pre-school children with specific language impairment (SLI) and typically-developing (TD) controls was compared on the Peabody Picture Vocabulary Test third and fourth edition (PPVT-III and PPVT-IV) to determine consistency in performance and the effect of test revision on identification of impairment. Participants included 40 pre-school children with SLI and 40 controls. Tests were administered in counterbalanced order.

Specific language impairment and executive functioning: parent and teacher ratings of behavior.

Purpose: The current study used the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P; Gioia, Espy, & Isquith, 2003), a rating scale designed to investigate executive behaviors in everyday activities, to examine the executive functioning of preschool children with specific language impairment (SLI) relative to their typically developing (TD) peers.

Method: Nineteen preschool children with SLI were age- and gender-matched to 19 TD peers. Both parents and teachers of the participants completed the BRIEF-P.
