Resumen

La minimización de síntomas es un problema relevante para la evaluación psicológica. La mayoría de los estudios utilizan diseños de simulación. Este estudio tiene como objetivo comparar la prevalencia de la minimización de síntomas y sus implicaciones, utilizando indicadores de escala única y de escala múltiple del Inventario Multifásico de Personalidad de Minnesota-2 (MMPI-2) en muestras reales. Utilizando un diseño de Grupo de Prevalencia Diferencial se evaluaron 1438 participantes, agrupados en tres muestras: dos no clínicas (comunitario y organizacional) y una muestra clínica. La muestra organizacional tuvo la mayor prevalencia de minimización de síntomas. En general, el indicador de escala múltiple LKS ≥ T65 proporcionó los mejores resultados. El análisis de la varianza reveló que el LKS ≥ T65 era también el único indicador de diferenciación, en las escalas clínicas, de los participantes que realizaban o no la minimización de síntomas, a la vez que tenía una menor probabilidad de producir errores tipo I y II. La presencia de minimización tiene una clara implicación en las puntuaciones clínicas. El indicador de escalas múltiples es el más robusto en la detección de la minimización de síntomas y es relevante para la evaluación en diferentes contextos, principalmente en lo organizacional.
