AI Article Synopsis
- Language comprehension is crucial for children's social and educational growth, but there are limited pediatric tests available to measure it.
- Two versions of the Token Test (TT), namely the TT short form and the Revised Token Test (RTT), were compared using a sample of 88 Spanish-speaking children, leading to the selection of the RTT for further testing due to its superior performance.
- The RTT was then validated against a developmental measure of vocabulary across a larger group of 250 children aged 4-12, showing strong concurrent validity and revealing age-related differences and a three-factor structure in its analysis.
Article Abstract
Language comprehension is vital to social and educational development but few pediatric tests are available for its assessment. To approach this problem, two versions of the Token Test (TT), "TT short form" (DeRenzi & Faglioni, 1978) and "Revised Token Test" (RTT), were first compared. Using a sample of 88 normally developing Spanish-speaking children, the tests were compared on their: (a) established psychometric development and (b) internal consistency. The RTT was judged to be superior and was selected for additional experimentation. The RTT was compared with a developmental measure of lexical knowledge on a cross-sectional sample of 250 4-12-year-old normally developing Spanish-speaking children. A significant positive and high correlation supports its concurrent validity. Significant differences across the age groups, along with a principal component analysis that yielded a three-factor structure, support its construct validity. Preliminary normative data across the nine age groups are provided.
