Stability of WAIS-R scatter indices in the elderly.
The test-retest reliability and clinical stability of WAIS-R VIQ-PIQ differences, inter, and intrasubtest scatter were investigated in a sample of 61 normal persons 75 years and older. The test-retest coefficient was.76 for VIQ-PIQ discrepancy, ranged from.05 to.56 for the intersubtest scatter range, and from.08 to.43 for intrasubtest scatter. In terms of clinical stability, 56% of subjects mai...
متن کاملTest-retest reliability and minimal detectable change for center of pressure measures of postural stability in elderly subjects
Abstract Background: Postural instability has been identified as a potential precursor of falls in elderly subjects. Postural stability in quiet stance is commonly assessed with center of pressure (COP) measures. The purpose of this study was to determine testretest reliability and minimal detectable change (MDC) for the center of pressure (COP) measures in the elderly subjects. Met...
متن کاملTest-retest stability of the Continuous Visual Memory Test in elderly persons.
Ninety-two normal elderly persons were administered the Continuous Visual Memory Test (CVMT) on two occasions an average of 1.1 years apart. Means for age and education were 69.02 years (SD = 5.79) and 14.80 years (SD = 2.64), respectively. Stability coefficients were.49 on the Total score,.44 on d-prime, and.48 on Delayed Recognition. D-Prime and Delayed Recognition scores demonstrated signifi...
متن کاملVisuospatial characteristics of an elderly Chinese population: results from the WAIS-R block design test
Visuospatial deficits have long been recognized as a potential predictor of dementia, with visuospatial ability decline having been found to accelerate in later stages of dementia. We, therefore, believe that the visuospatial performance of patients with mild cognitive impairment (MCI) and dementia (Dem) might change with varying visuospatial task difficulties. This study administered the Wechs...
متن کاملThe Mahalanobis Distance index of WAIS-R subtest scatter: psychometric properties in a healthy UK sample.
Burgess (1991) has proposed a new index of subtest scatter for the WAIS-R which uses a test statistic, the Mahalanobis Distance (MD). When used with the WAIS-R, MD scores should be distributed as chi square with 11 degrees of freedom. The suitability of the MD index for UK clinical practice was assessed by examining its psychometric properties in a sample of 200 healthy subjects. The sample, wh...
