Ryan, Joseph J.; Gontkovsky, Samuel T. – Journal of Psychoeducational Assessment, 2021
We analyzed data from the WASI-II manual to determine discrepancy score reliabilities of the Verbal Comprehension (VCI) and Perceptual Reasoning (PRI) indexes and the four subtests in the child and adult standardization samples. Reliabilities of the VCI-PRI discrepancy scores range from 0.78 to 0.86 for children and 0.82 to 0.89 for adults and…

Ryan, Joseph J.; Glass Umfleet, Laura; Gontkovsky, Samuel T. – Journal of Psychoeducational Assessment, 2021
This investigation provides internal consistency reliabilities for the Wechsler Memory Scale--Fourth Edition (WMS-IV) subtest and index discrepancy scores using the standardization samples of the Adult and Older Adult batteries. Subtest reliabilities ranged from 0.00 to 0.93 for Adults and 0.25 to 0.94 for Older Adults. Three of 91 Adult…

Prifitera, Aurelio; Ryan, Joseph J. – Journal of Consulting and Clinical Psychology, 1981
Investigated the validity of the Luria-Nebraska Intellectual Processes Scale (IPS) as a substitute for the Wechsler Adult Intelligence Scale (WAIS). IPS scores were correlated with the three WAIS IQs, and regression equations were computed to obtain estimated Verbal IQ, Performance IQ, and Full Scale IQ. (Author)

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…

Ryan, Joseph J.; Bohac, Daryl L. – Psychological Assessment, 1994
The clinical utility of the cluster solution of core profiles of the Wechsler Adult Intelligence Scale-Revised by McDermott and others (1989) was studied with 161 brain-damaged patients. Core profile methodology was not sensitive to brain damage and lacked neurodiagnostic utility. (SLD)

Ryan, Joseph J.; And Others – Psychological Assessment, 1992
Validity of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) intersubtest scatter as an indicator of cognitive impairment due to brain dysfunction was studied with 316 brain-damaged men. When compared with the WAIS-R standardization sample, intersubtest scatter was not greater for normal persons of similar intelligence quotient. (SLD)

Ryan, Joseph J.; And Others – Psychological Assessment, 1992
Intersubtest scatter on the Wechsler Adult Intelligence Scale-Revised for China (WAIS-RC) for 1,979 subjects was evaluated and compared with that of the WAIS-R standardization sample. Findings were similar, and differences in scatter range may be explained by cultural differences in values, educational approaches, and educational opportunities.…
