Hopkins Verbal Learning Test-Revised (HVLT-R) Total Recall and Delayed Recall T-score formula including site (California, Arizona) as a predictor

HVLT-R	$10\times \left(\frac{\text{SS}+\text{HVLT}-\text{R Total Recall }-\left(\mathbf{7.2650}-\mathbf{4.0909}*\frac{\mathit{\text{age}}}{100}+\mathbf{2.7952}*\frac{\left(\text{edu}+1\right)}{10}-\mathbf{1.1726}*\text{sex}+2.0687\times \text{site }\right)}{\mathbf{2.5409}}\right)+50$

HVLT-R	$10\times \left(\frac{\text{SS\hspace{0.17em}HVLT}-\text{R Delayed Recall }-\left(\mathbf{7.2024}-\mathbf{3.1964}*\frac{\mathit{\text{age}}}{100}+\mathbf{2.8065}*\frac{(\text{edu}+1)}{10}-\mathbf{0.7775}*\text{sex}+1.5436\times \text{site }\right)}{\mathbf{2.6147}}\right)+50$

Note. These formulas should be applied to education level ranges from 0–20 and age 19–60. Using values outside these ranges might result in extrapolation errors. Sex: Male=1; Female=0. Site: CA=1; AZ=0. California (CA)=1; Arizona (AZ)=0. California N = 139; Arizona N = 62. SS=observed scaled score; Edu=years of education; Age=years of age.
