title: Development of the Greek Verbal Learning Test: reliability, construct validity, and normative standards.
abstract: We developed a multiple-form list learning test appropriate for use with the Greek population and generated norms for clinical and research use. This task, the Greek Verbal Learning Test (GVLT), was based on the California Verbal Learning Test. We administered the standard version (Form A) to a sample of 354 healthy individuals, as well as two alternative forms (B and C) to a subgroup of the initial sample. Performance on the three forms was equivalent, and each test presented excellent internal consistency. We found good sensitivity and specificity in the testãs (Form A) utility in differentiating individuals with schizophrenia (n = 50) and individuals with traumatic brain injury (n = 53) from healthy adults. A multiple regression analysis indicated that age, education and sex predicted performance. Regression-based norms are also provided. Taken together, these data provide preliminary support for the reliability and construct validity of the GVLT.
