Abstract：
:The Attention Network Test (ANT) is a frequently used computer-based tool for measuring the three attention networks (alerting, orienting, and executive control). We examined the psychometric properties of performance on a variant of the ANT, the Attention Network Test-Interaction (ANT-I) in healthy older adults (N = 173; mean age = 65.4, SD = 6.5; obtained from the Brain in Motion Study, Tyndall et al. BMC Geriatr 13:21, 2013. doi: 10.1186/1471-2318-13-21) to evaluate its usefulness as a measurement tool in both aging and clinical research. In terms of test reliability, split-half correlation analyses showed that all network scores were significantly reliable, although the strength of the correlations varied across networks as seen before (r = 0.29, 0.70, and 0.68, for alerting, orienting, and executive networks, respectively, p's < 0.05). In terms of construct validity, ANOVAs confirmed that each network score was significant (18.3, 59.4, and 109.2 ms for the alerting, orienting, and executive networks, respectively, p's < 0.01) and that these scores were generally independent from each other. Importantly, for criterion validity, a series of hierarchical linear regressions showed that the executive network score, in addition to demographic information, was a significant predictor of performance on tests of conflict resolution as well as verbal memory and retrieval (β = -0.165 and -0.184, p's < 0.05, respectively). These results provide new information regarding the reliability and validity of ANT-I test performance in a healthy older adult population. The results provide insights into the psychometrics of the ANT-I and its potential utility in clinical research settings.
