Abstract
Numerous studies have attempted to validate nonverbal fluency tests but none have examined construct validity, particularly the correlation of measures and self-reported executive functioning deficits. The current study examined this issue by correlating the results of the Five-Point Test (5PT) and the Delis Kaplan Executive Functioning System (D-KEFS) Design Fluency Test with the Barkley Deficits in Executive Functioning Scale – Short Form (BDEFS-SF) in 306 English speaking adults. Participants were volunteers from undergraduate classes and those serving jury duty in a large urban city. The mean age was 36.89 ± 18.08 with an average of 14.65 ± 2.85 years of education. The majority was female (70.3%), Caucasian (76.0%), and had a primary language of English (97.7%). Results were unable to confirm the previous literature showing adequate test-retest reliability across all scores for the 5PT and for the D-KEFS Design Fluency Test as only rotation of the 5PT (rs=.84) as having good reliability. In analyzing the scales of the BDEFS-SF, the study found only a few inconsistent meaningful correlations between the summary and strategy scores of the 5PT and scales of the BDEFS-SF. When controlling for age and education, repetitions for the 5PT and the DKEFS Design Fluency Test correlated significantly with most of the scores on the BDEFS-SF, supporting repetitions on nonverbal fluency tasks as measures of executive dysfunction. A mediation analysis was significant such that education mediated the relationship between age and number of unique designs on the 5PT, b = .086, 95% BCa CI [.035, .138], as well as for the relationship between age and strategies used on the 5PT, b = .069, 95% BCa CI [.014, .122]. In general, small insignificant correlations were found between the summary scores of the two nonverbal fluency measures and the self-report measure of executive functioning, further suggesting the link between self-report of such deficits and actual deficits is tenuous at best. These findings also indicate that higher education is neuroprotective against cognitive decline.
