Memory assessment plays an important role in the diagnosis of neurodegenerative disorders. Several tests, such as the California Verbal Learning Test (CVLT), have been developed for this purpose, yet a variety of different factors can affect one's performance on such tests, the most important of which are demographic and cultural variables. The present study examined the norming process performed on the CVLT-revised and aimed to devise a new test, the Shiraz Verbal Learning Test (SVLT), to better meet the needs of speakers of Persian.
In order to collect normative data, a group of 1275 Persian-speaking individuals consisting of both sexes (676 women and 599 men) aged 20-89 years old were selected for this study.
The results of Pearson's Correlation analysis indicated that there was a significant negative correlation between age and SVLT performance and a positive one between education and SVLT performance (p < .001) among the whole sample. Moreover, between-group analyses showed that the female participants performed significantly better than their male counterparts on nearly all subtests (Total Trails 1-5, Short-Delay Free Recall, Short-Delay Cued Recall, Long-Delay Free Recall, Long-Delay Cued Recall, and Total Learning Slope), with the only exception being Long-Delay Yes/No Recognition.
These results suggest that the SVLT has the potential to be further developed among different culture and language groups. This test can also be used for clinical and research purposes for patients with neuropsychiatric disorders who need further neuropsychological assessment.
