a series of studies was conducted to examine the validity and reliability using the test performance of the entire norming group and several subgroups. the inclusion of auditory processing subtests is a unique and critical contribution to the digital assessment market. a series of studies was conducted to examine the validity and reliability of the gibson test of cognitive skills (version 2) using the test performance of the entire norming group and several subgroups. there are 14 puzzles on the test for a total of 92 possible points. the examinee listens to a nonsense word and is told to delete part of the word to form a new word. the complete auditory processing test comprised 45 items for a total of 72 possible points.
in the second phase of the study, the test was administered to students and staff members in 23 different elementary and high schools. reliability of the gibson test of cognitive skills battery was also evaluated by correlating the scores on two halves of each test. in the 18–29 years age group, gender was a significant predictor of score differences on the test of auditory processing, p<0.001, r2=0.02, b=−5.8. the results indicate that the gibson test is a valid and reliable measure of assessing cognitive skills in the general population. with growing emphasis on age-related cognitive decline, the test may serve as a useful adjunct to brain care and intervention with an aging population. although the current study noted a few score differences by gender in the adult sample, it is important to note that only 2% of the individual items showed differential item functioning for gender during the test development stage.29 regardless, the current study provided multiple sources of evidence of the validity and reliability of the gibson test of cognitive skills (version 2) for use in the general population for assessing cognition across the lifespan.
the split-half reliability coefficients ranged from 0.83 to 0.96 overall, producing a strong second source of reliability evidence. the gibson assessment of cognitive skills (gacs)32 is a paper-based cognitive screening tool based on chc theory. the logic and reasoning test measures inductive reasoning skill, or the ability to infer a rule based on the observation of a phenomenon. for each item, the examinee is shown a matrix of designs with a missing space and he must select from a set of designs the one that fits in the missing space. following collections of the test forms, the data were transferred to spreadsheets for analysis to calculate internal consistency reliability and split-half reliability on the whole sample (n = 103), and test–retest reliability for each subtest on the second half of the recruited sample (n = 53). a spearman-brown formula was applied to the pearson correlation for each subtest to predict the overall reliability of the test. we were pleased with the strong reliability of this portion of the gacs in particular since it is a unique aspect of the test compared to other assessments in widespread use.
