Validity and reliability of the Arabic Token Test for children

Area of Science:

• Linguistics
• Speech-Language Pathology
• Psychometrics

Background:

• The Token Test for Children (TTFC) is a standard measure for assessing receptive language skills.
• A validated Arabic version is needed to assess Arabic-speaking children with language impairments.

Purpose of the Study:

• To translate, validate, and establish the reliability of the Arabic Token Test for Children (A-TTFC).
• To provide a culturally and linguistically appropriate tool for assessing receptive language in Arabic-speaking children.

Main Methods:

• The A-TTFC underwent a rigorous translation process adhering to international guidelines.
• Pilot testing and amendments were conducted before final administration.
• The final A-TTFC was administered to 397 typically developing Jordanian children (age 3-12) and 35 bilingual children for validation.

Main Results:

• Factor analysis confirmed construct validity, with item loadings similar to the English TTFC.
• Internal consistency (alpha coefficients) ranged from 0.78 to 0.94.
• Bilingual validity (ICC > 0.80) and test-retest reliability (ICC 0.76-0.90) were established.

Conclusions:

• The A-TTFC is an appropriate and reliable instrument for assessing receptive language problems in Arabic-speaking children.
• The study provides strong psychometric evidence supporting the use of the A-TTFC.
