A French adaptation of the internal and external encoding style questionnaire and its relationships with impulsivity

Recent research has revealed the existence of individual differences in how preexisting schemata (versus cues from the outside world) affect encoding processes, which can be reliably assessed with the internal and external encoding style questionnaire (ESQ) [Lewicki, P. Internal and External Encoding Style and Social Motivation. In: J. P. Forgas, K. D. Williams, S. M. Laham, (Eds.), Social Motivation: Conscious and Unconscious Processes. Psychology Press, New York (2005). pp. 194-209]. The present study was designed to (1) test the psychometric properties of a French version of the ESQ and (2) explore in-depth its relationship with impulsivity - a trait of central importance in the understanding of emotional psychopathology, and which has been previously related to the internal encoding style. Sixty-three participants were tested using the French versions of the ESQ and the UPPS impulsive behavior scale. The UPPS identifies four distinct facets of impulsivity: urgency, lack of premeditation, lack of perseverance, and sensation seeking. The results showed (1) that the French version of the ESQ has good psychometric properties and (2) that consistent with theoretical considerations, internal encoding style is related to two specific out of the four components of impulsivity: high urgency and low perseverance. © 2008 Elsevier Masson SAS.
