Translated abstract

In this article we present the results of the reliability studies of the new EIWA III, Escala de Inteligencia Wechsler para Adultos Versión III, Puerto Rico (translation, adaptation and standardization of the WAIS III). These studies support the strength of the EIWA-III's internal consistency and temporal stability. We conclude that the EIWA-III is a valid and reliable instrument for the intellectual assessment of the adult population of Puerto Rico.

Practice effect and test-retest reliability of attentional and executive tests in middle-aged to elderly subjects.

Kate S LeMay, Isabelle Rouleau, Pierre-Luc Tremblay … (2004)

There is a lack of data about the practice effect and test-retest reliability (TRR) on many attentional and executive tests in neuropsychology. In this study, 37 subjects aged 52 to 80 were tested three times with an inter-assessment interval of 14 days. The battery included the Rey Auditory Verbal Learning Test, the Stroop interference test, the Letter-Number Sequencing test, Wechsler Adult Intelligence Scale-III (WAIS-III), the Ruff 2 and 7 Selective Attention Test, the Tower of London, the Verbal Fluency test, and simple, choice, and sequential reaction time tests. The results showed that tasks were generally subject to a practice effect, except for those with alternate forms. In all tests, there were a number of scores demonstrating good TRR, but others, although largely used in clinical practice, failed to reach acceptable TRR standards. Usually, time derived scores were associated with the best TRR.
