The present study reports the divergent association between social desirability and the responses to MBI-GS and UWES, 2 instruments that measure constructs considered opposite: burnout and engagement. This relationship has been explored very little, and even less in Hispanic subjects. The participants were employees of retail shops in the central zone of metropolitan Lima. It was found that social desirability shares variance with the scores of emotional exhaustion and indifference, but this relationship was influenced by the instrument that measures social desirability. The partial correlations between the MBI scores showed practically no difference from their zero order correlations. The UWES did not co-vary with social desirability. It is concluded that social desirability has little influence on scores oriented toward the burnout in the MBI.
