![]() The present results provide support for the temporal reliability of the SB-IV and its concurrent, criterion-related validity in an exceptional sample. Moderate correlations were observed between the VABS composite and SB-IV composite scores. Individual subtest correlations tended to be lower but consistent across the two administrations. The test-retest reliability coefficients for the four SB-IV area and composite scores were all significant (P < 0.00). The Vineland Adaptive Behavior Scale: Interview Edition (VABS) was completed by a reliable informant within one week of the SB-IV testing. ![]() The Standards for Educational and Psychological Testing (AERA, APA, NCME, 2014) have defined these attributes as follows: Validiyt is the degree to which evidence and theory support the interpretations of test scores for proposed uses of tests (p. ![]() ![]() Forty adults with mild to moderate intellectual disability (mean age = 20.8 years SD = 1.8 years) were administered the SB-IV and retested approximately 5 weeks later (mean = 33.4 days, SD = 1.2). test scores and their use: validity, reliability, and fairness. The test-retest reliability and concurrent, criterion-related validity of the Fourth Edition of the Stanford-Binet Intelligence Scale (SB-IV) were examined in a young adult population with intellectual disability. ![]()
