Forma abreviada de la WAIS-IV: estudio piloto en pacientes con esquizofrenia

subject

description

The aim of this study is to develop a WAIS-IV short form of the Spanish version for its use with schizophrenia patients, which would allow estimating their intellectual capacity in a short period of time (approximately 30 minutes). The sample was composed by a clinical group consisting of 35 schizophrenia patients and a control group consisting of 35 people with no known history of mental illness. Data demonstrated that the best combination of tests was: Similarities (Verbal comprehension), Visual puzzles (Perceptual reasoning), Arithmetic (Working memory) and Coding (Processing speed). With this short form, it was possible to obtain a linear correlation between the IQ of the full scale and that of the abridged form of 0.941 in the clinical and 0.940 in the control group. For both groups, the differences between the real IQ averages and the estimated ones were not significant. Moreover, the short form is capable of classifying a substantial number of people in the same IQ category than the full scale does.
