The computerized continuous performance task: a new measure of inattention.

Attentional performance was measured using a computerized continuous performance task, several psychometric tasks, and ratings of classroom behavior. Subjects were 51 children in the inpatient and day hospital programs of a psychiatric hospital. The relationship between performance on the computerized task and all other measures was examined. Results indicated that the continuous performance task significantly correlated with several other psychometric measures of inattention, ratings of inattention, impulsivity, and hyperactivity. The CPT had slightly better sensitivity and the same specificity as the Conners Teacher Rating Scale in identifying Conduct and Attention Deficit Disordered children. Implications for the use of the computerized continuous performance task as a screening measure for attentional difficulties is discussed.
