Abstract

Introduction

Individuals diagnosed with schizophrenia have significant cognitive deficits. However, the subjective perception of these deficits do not always coincide with the neuropsychological test and clinical ratings.

Methodology

This study evaluates the cognitive performance of 46 outpatients with schizophrenia, in a Psychosocial Rehabilitation Program, by three different measures: neuropsychological tests (objective assessment), cognitive factor of PANSS (clinical ratings), and subjective scale of cognition, SSTICS (patient self-report). It also studies the possible relationship between subjective assessment of cognitive symptoms and insight of the mental disorder (SUMD).

Results

SSTICS total score correlated only with some neuropsychological subtest, but not with cognitive factor of PANSS. The clinical ratings is more consistent with neuropsychological test than the cognitive complaints. No relationship between SUMD and SSTICS.

Conclusions

Because of the lack of correspondence among several measures, it is possible to think that different cognitive areas have been evaluated. It is therefore important to consider all assessment options in order to create cognitive rehabilitation programs. Cognitive complaints seems to be an independent variable of insight.

Resumen

Introducción

La mayoría de las personas diagnosticadas de esquizofrenia presentan déficit cognitivos. No obstante, la percepción subjetiva de esos déficit no siempre coincide con la evaluación neuropsicológica ni con la evaluación clínica de aquéllos.

Metodología

En este trabajo se evaluó el rendimiento cognitivo de 46 pacientes con esquizofrenia que acuden a un centro de rehabilitación psicosocial, mediante tres pruebas diferentes: una batería neuropsicológica, el test Barcelona (evaluación objetiva), una escala de síntomas cognitivos, el factor cognitivo de la PANSS (evaluación clínica) y una escala subjetiva de cognición, la SSTICS (autoevaluación del paciente). También se estudiaron las relaciones entre la percepción subjetiva de síntomas cognitivos y el insight de la enfermedad, evaluado mediante la SUMD.

Resultados

La puntuación total de la SSTICS se correlacionó sólo con algunos de los subtests del Barcelona, pero no con el factor cognitivo de la PANSS. La evaluación clínica se corresponde con los tests neuropsicológicos en mayor medida que con la percepción subjetiva. No hay relaciones entre la percepción sujetiva de los déficit cognitivos y el insight.

Conclusiones

Dada la falta de correspondencia entre las diferentes medidas, se plantea si podrían estar evaluando ámbitos diferentes del deterioro cognitivo. Se valora la importancia de considerar todas las opciones de evaluación con vistas a elaborar programas de rehabilitación cognitiva. La percepción de déficit cognitivos parece ser independiente del insight.
