Performance Data for Traumatic Brain-Injured Subjects on the Gordon Diagnostic System (GDS) Tests of Attention

Abstract

Thirty adults with traumatic brain injury (TBI) (20 males and 10 females, mean age 40 years) and a non-injured control group (12 males and 13 females, mean age 41 years) were tested on 16 tests of attention including three tasks of the Gordon Diagnostic System (GDS), a relatively new set of attention tasks. No differences between groups were found on age or education. Both groups had estimated IQs in the average range. Performance data for the GDS are presented for the TBI and CON groups. Mild to moderate deficits of attention were seen in the TBI group relative to controls on the Vigilance and Distractibility tasks. No differences between groups were seen on the Standard Delay groups. Person product moment correlations suggested different patterns of relationships between the GDS tasks and other tests of attention for the TBI and CON groups. These results support the utility of the Vigilance and Distractibility tasks for assessment of attention in a mild to moderately injured population.

Continuous Performance Tests Are Sensitive to ADHD in Adults but Lack Specificity

“…A number of studies have investigated the level of association between the Stroop task79 and CPT performance 128,158,161–163. Moderate correlations were found between the Stroop and CPT164,165; only in one study was the correlation not found to be at least moderate 163…”

“…Depending on the study, adults with other disorders also had impaired performance. For example, Burg and colleagues164 compared the performance of subjects with TBI to a control group. Performance of the 30 TBI subjects (mean age 40.0 years) suggested mild to moderate deficits on vigilance and distractibility tasks.…”

Characterization of EEG patterns in brain-injured subjects and controls after a Snoezelen® intervention

“…One possible explanation for this fact is related to cognitive deficits in TBI and CP groups, since mild to moderate deficits of attention have been proved in brain-injured subjects in comparison with controls [48]. This lack of attention may diminish the benefits for CP and TBI groups.…”

Behavioural differences between psychiatric patients with confirmed versus non-confirmed traumatic brain injuries

“…For both the Vigilance and Distractability conditions, the total number of correct responses was utilized for statistical analysis. Data on these measures are available for college students [40], persons with TBI [27], and psychiatric patients [41]. [42] This was administered to measure span of immediate verbal recall.…”
