The California Verbal Learning Test-II: normative data for two Italian alternative forms.

The aim of this study was to develop two versions of the California Verbal Learning Test-II (CVLT-II) and to administer them to a large sample of healthy controls representative of the normal Italian population for sex, age, and education levels. Two hundred and eighty healthy controls entered the study and were randomly assigned to one of the two forms of CVLT-II. No significant difference emerged between the two forms. Considering the significant weight of sex, age and education level, a regression model was developed through which it was possible to calculate the adjusted scores. The lower tolerance limits were also calculated.
