Adaptation et validation d’une version brève en langue française du questionnaire d’impulsivité de Barratt (BIS-15)

Conclusions Des considérations relatives aux échelles de réponse employées dans les questionnaires et aux modes d’examen sont présentées en conclusion. Introduction The Barratt Impulsiveness Scale is one of the most frequently used questionnaires to assess impulsivity. Many versions of the questionnaire were developed during the 50 years that followed its creation. Objectives This article reports validation data for a French-language version of Spinella's (2007) BIS-15 questionnaire, a short version of Barratt's original scale (BIS-11; Patton, Standford, & Barratt, 1995). Method Reliability, principal component analyses and confirmatory factor analyses have been conducted with two university student samples (study 1, n =366; study 2, n =322). Results The results of this study revealed a number of redundant items, which lead us to consider a unidimensional model with correlated measurement errors. Cronbach's alpha reliability was acceptable for study 1 (0.71), and satisfactory for study 2 (0.81). Test-retest reliability was also satisfactory (0.84). Elements of external validity (correlations with anxiety, neurosis, and extraversion) are reported. Conclusions Considerations regarding the type of response scales and assessment methods used in questionnaires are discussed in the conclusion.
