The study aimed to evaluate the validity of the Arabic translations of the Vanderbilt ADHD Diagnostic Scale (VADRS-A) through analyses involving parents and teachers in Saudi Arabia.
It included a sample of 1,812 participants, assessing children aged 5 to 12, with parents rating the Arabic Vanderbilt ADHD Diagnostic Parent Rating Scale (VADPRS-A) and teachers using the Arabic Vanderbilt ADHD Diagnostic Teacher Rating Scale (VADTRS-A).
Results showed a strong consistency and correlation among the factors of both scales, with high percentages of variance explained (59% for VADPRS-A and 69.20% for VADTRS-A), indicating their effectiveness in diagnosing ADHD.
