title: When self-report diverges from performance: the usage of BIS-11 along with neuropsychological tests.
abstract: Impulsivity has been fractionated into multiple independent, but correlated, components. Personality and neuropsychological studies have consistently shown its multidimensional nature. Each theoretical approach uses different techniques such as self-report questionnaires and neuropsychological tests to assess impulsivity, respectively. Our main objective was to investigate if there is evidence of convergent validity for impulsivity as assessed by both types of measures. We administered the Barratt Impulsivity Scale 11 and two neuropsychological tests (Iowa Gambling Task and Continuous Performance Task) to 266 participants to measure inhibition control and non-planning impulsivity dimensions. Results from an exploratory factorial analysis and group comparison indicated there was little evidence of convergent validity between the two types of measures. These findings are discussed in terms of impulsivity as a multi-factorial construct as well as the specific instruments used for assessment. Implications for psychological theory and impulsivity assessment were also proposed.
