Abstract
Introduction: In recent years, providing virtual rehabilitation services has become an accepted clinical approach. The findings of studies using telerehabilitation indicate challenges with the validity of scores obtained through this approach to language assessment. As a result, the virtual evaluation of patients must be conducted in accordance with valid frameworks. This pilot study aims to evaluate the validity of the virtual version of the parallel picture-naming test (PPNT).
Materials and Methods: In this descriptive-analytical, cross-sectional study, two versions of the PPNT, each consisting of 109 black-and-white line drawings of Persian nouns, were prepared for virtual presentation. Five speech therapists determined the face validity of the virtual versions. Then, the virtual test was administered to 30 healthy adults, and test-retest reliability and equivalent versions were calculated.
Results: The versions A and B of PPNT demonstrated acceptable levels of simplicity, clarity, and comprehensibility, with mean impact scores ranging from 4.1 to 4.4 and content validity indices (CVI) between 0.99 and 1.0. The intraclass correlation coefficients (ICCs) obtained for version A and version B were 0.88 and 0.79, respectively, which were significant (P < 0.001). The difference in scores between the two versions of the virtual test was not significant (P = 0.450).
Conclusion: The virtual versions of PPNT have acceptable face validity and reliability. Given the importance of evaluating naming skills in linguistic and cognitive assessments, these tests can serve as viable virtual tools for the remote evaluation of word-retrieval deficits. Further research across diverse patient groups is recommended.
