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 also be conducted in accordance with valid frameworks. In this initial study, we examine the validity of the virtual version of the parallel picture naming test.
Materials and Methods: In this descriptive-analytical cross-sectional study, two versions of the Parallel Picture Naming Test (PPNT), each consisting of 109 black-and-white linear pictures of Persian names, 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 images of versions A and B of PPNT had acceptable average impact scores (4.1 to 4.4) and content validity indices (0.99 to 1) for simplicity, clarity, and comprehensibility. The 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 also not significant (P = 0.450).
Conclusion: The virtual format of parallel A and B naming tests has suitable face validity and reliability. Given the importance of evaluating naming skills in language and cognitive evaluations, these tests can serve as suitable virtual tools for assessing word retrieval problems remotely. More research on the patient groups is recommended.
