This study investigated the application of item quadruplets to control social desirability in measuring socio-emotional competencies and their relationship with intelligence. Quadruplets involve four variations of an item, differing in the polarity of their descriptive content and evaluative content (social desirability): positive-desirable, negative-desirable, positive-undesirable, and negative-undesirable. The sample consisted of 431 individuals aged 18-67, predominantly female (71.1%). To control social desirability, items were manipulated in quadruplets. The results indicated a superior model fit when a general social desirability factor was estimated, with factor loadings reinforcing the presence of a general evaluative content factor. Additionally, controlling for this general factor led to more interpretable and enhanced loadings for the descriptive factors, affirming the hypothesis that controlling a general evaluative factor improves the theoretical congruence. The study also found negative correlations between intelligence and both social desirability and extroversion. The findings support the effectiveness of the quadruplets method in assessing social desirability.
