Objective: The Automated Neuropsychological Assessment Metrics General Neuropsychological Screening battery (ANAM GNS) is a collection of computerized tests designed to assess general cognitive functioning. Computerized tests offer an alternative to traditional neuropsychological tests (NPT) which often lack the flexibility and convenience associated with computerized tests. Currently there is limited research comparing ANAM to the NPT upon which it is based. This study examined convergent validity of the ANAM GNS in outpatients referred for neuropsychological assessment. Methods: Participants (N = 143) ranged in age from 18-85 (M = 59.6, SD = 16.6) and were referred secondary to cognitive concerns or complaints. ANAM was administered following a comprehensive neuropsychological evaluation. Correlations were examined between ANAM and the Repeatable Battery for the Assessment of Neuropsychological Status, Trail Making Test, Rey Auditory Verbal Learning Test, and selected subtests of the Wechsler Adult Intelligence Scale-III. Results: There were a large number of statistically significant correlations between ANAM and NPTs, particularly for tests relying on speed of performance. Moderate to strong correlations were observed between ANAM and NPTs measuring parallel domains. The highest correlations (r = .60–.70) were observed for tests of learning, attention, and visual recognition memory. Moderate correlations were also seen between ANAM tests and NPTs measuring general cognitive functioning (e.g., Vocabulary and Matrix Reasoning). Conclusion: The ANAM GNS battery showed good convergent validity with traditional neuropsychological tests in a mixed clinical sample. Not surprisingly, convergent validity was good between ANAM and NPTs measuring attention and processing speed, but was also seen for tests of general verbal and nonverbal abilities, supporting ANAM's use as a general cognitive screening measure.
