Evaluation of self-deception: Factorial structure, reliability and validity of the SDQ-12 (self-deception questionnaire).

We all need to resort to deception, either with ourselves (denial, self-deception, mystification) or with others (with modalities, such as impression management, social desirability), to a greater or lesser extent. Lies, in their broader meaning, are interpreted as something rather adaptive, useful, and necessary in our socioaffective world. In particular, self-deception is a highly interesting psychological concept in the clinical population, namely, in drug dependents, as it serves as a mechanism for maintaining addiction.
