The psychometric properties of the WISC-IV verbal comprehension and working memory indices among visually impaired students in Sudan

Year: 2025

Type: article

Abstract: Background: Intelligence testing in Sudan began in 1946, with efforts to adapt and validate international assessments starting in 1964. However, no intelligence test had been specifically tailored for students with visual impairments. Aims: This study aimed to fill this gap by adapting the Verbal Comprehension and Working Memory indices of the WISC-IV for use with visually impaired children and assessing their reliability and validity. Methods: The study involved 166 visually impaired students (57.83% male, 42.17% female), aged 6-16 years, drawn from schools in Khartoum. Results: The adapted indices demonstrated strong reliability and validity, supporting their suitability for use with Sudanese students who have visual impairments. Conclusion: The findings support the use of the adapted Verbal Comprehension and Working Memory indices to assess verbal intelligence in visually impaired students in Sudan for both diagnostic and evaluative purposes.
