Convergent and predictive validity of two computerized attention tests in brain-damaged patients

Abstract

Although computerized attention tests are used frequently, our knowledge about the convergent and predictive validity of these tests is limited. In the present study, 47 stroke and traumatic brain injury patients performed the Attention Network Test (ANT) and corresponding subtests of the Test for Attentional Performance (TAP). In addition, patients and staff completed the Attention Deficits Questionnaire (ADQ). Considering corresponding ANT and TAP subtests, significant correlations (r = .55 – .71) were found for alerting and orienting subtests and overall reaction time. Comparison of subtests of the two attention tests with staff reported deficits in the ADQ revealed moderate to high correlations for ANT (r = .62 – .70) and TAP (r = .36 – .86). The predictive validity of different subtests varies only sightly. The overall reaction time seems to be the best predictor of rated attention deficits. Findings support the convergent and predictive validity of both computerized attention tests.
