On Interpreting the Several Standard Errors of the WAIS-R: Some Further Tables.
Peer reviewed Peer reviewed
Knight, Robert G. – Journal of Consulting and Clinical Psychology, 1983
Discusses the significance of confidence intervals around IQ scores based on a misleading interpretation of the standard error of measurement terms provided in the Wechsler Adult Intelligence Scale-Revised (WAIS-R) manual. Presents standard error values and a table for determining the abnormality of verbal and performance IQ discrepancies.…

Reliability of the WAIS-R with a Mixed Patient Sample.
Peer reviewed Peer reviewed
Ryan, Joseph J.; And Others – Perceptual and Motor Skills, 1982
An examination of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) subtests and intelligence quotients in a diagnostically heterogeneous sample of patients referred for psychological or neuropsychological evaluation found that reliabilities and standard errors of measurement approximated normative group reports. WAIS-R is a reliable…

Composite Reliability and Standard Errors of Measurement for a Seven-Subtest Short Form of the Wechsler Adult Intelligence Scale-Revised.
Peer reviewed Peer reviewed
Schretlen, David; And Others – Psychological Assessment, 1994
Composite reliability and standard errors of measurement were computed for prorated Verbal, Performance, and Full-Scale intelligence quotient (IQ) scores from a seven-subtest short form of the Wechsler Adult Intelligence Scale-Revised. Results with 1,880 adults (standardization sample) indicate that this form is as reliable as the complete test.…

Corrected Estimates of WAIS-R Short Form Reliability and Standard Error of Measurement.
Peer reviewed Peer reviewed
Axelrod, Bradley N.; And Others – Psychological Assessment, 1996
The calculations of D. Schretlen, R. H. B. Benedict, and J. H. Bobholz for the reliabilities of a short form of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) (1994) consistently overestimated the values. More accurate values are provided for the WAIS--R and a seven-subtest short form. (SLD)

Scoring Reliability on the WAIS-R.
Peer reviewed Peer reviewed
Ryan, Joseph J.; And Others – Journal of Consulting and Clinical Psychology, 1983
Wechsler Adult Intelligence Scale-Revised protocols from two vocational counseling clients were scored by 19 psychologists and 20 graduate students. Regardless of scorer's experience level, mechanical scoring error produced summary scores varying by as much as 4 to 18 IQ points. (Author/RC)

Reliability, Errors, Significance, and Abnormality: WAIS-R Factor Scores.
Atkinson, Leslie – 1990
Three tables are provided to aid in the clinical interpretation of factor scores for the Wechsler Adult Intelligence Scale-Revised (WAIS-R; 1981). The factor structure of the WAIS-R has proven to be robust across samples, tests, time, statistical analyses, measurement scales, and distortions of the distribution. Information necessary to make…
