A social desirability scale for the mmpi-2. Which of the two: Wiggins (wsd) or Edwards (esd)?

[ES] El objetivo de esta investigación pretende analizar comparativamente la precisión diagnóstica de dos escalas detectoras de Deseabilidad Social que han sido obtenidas de los 567 ítems que componen el Inventario Multifásico de Personalidad de Minnesota-2 (MMPI-2): la escala Wsd de Wiggins y la ESD de Edwards. Los 583 participantes (232 varones y 351 mujeres) fueron diferenciados en dos grupos según su forma de contestar: grupo sincero (N = 310), que contestaron de forma sincera siguiendo las directrices de MMPI-2, y simulador (N = 273), que fueron instruidos para mostrar intencionada y coherentemente una imagen favorable de sí mismos. Los resultados han demostrado una mayor precisión diagnóstica y poder predictivo, aunque menor fiabilidad (α de Cronbach), en la escala de Wiggins (Wsd) que en la de Edwards (ESD).
[EN] The objective of this research aims to comparatively analyze the diagnostic accuracy of two social desirability detection scales that have been obtained from the 567 items that comprise the Minnesota Multiphasic Personality Inventory-2 (MMPI-2): Wiggins Wsd Scale and Edwards ESD Scale. The 583 participants (232 men and 351 women) were differentiated into two groups according to their way of answering: Honest response group (N = 310) who replied truthfully following the guidelines of MMPI-2, and simulated response group (N = 273) who were instructed to intentionally and consistently show a positive image of themselves. The results have shown a higher diagnostic accuracy and predictive power, although less reliability (Cronbach's α) for the Wiggins (Wsd) Scale than for Edwards (ESD).
