Testing cognitive abilities by telephone in a sample of 6- to 8-year-olds

Telephone-administered measures of cognitive ability have been shown to be efficient and cost-effective alternatives to in-person-based assessments. The current study examined the validity of a telephone-assessed measure of cognitive ability using a sample of fifty-two 6–8-year-old children. The telephone test was composed of verbal- as well as performance-based measures of cognitive ability. The telephone-assessed measure of general cognitive ability correlated r=.65 with in-person-assessed measures. After correction for range restriction, the correlation was r=.72. Thus, measures of cognitive ability administered by telephone appear to be feasible, even in elementary school-age children.
