Results
The sex ratio is 1.02. Most of the interviewed persons were 20 to 49 years old. Around 25.4% of the sample were analphabets, 32.1% had primary education, 29.1% had secondary education and 13.4% were undergraduates. The Cronbach's alpha was respectively 0.66 for attention, 0.72 for motor impulsivity, 0.61 for lack of planning and 0.78 for total impulsivity. Factor analysis identified three factors explaining the total variance of 32.6%. Impulsivity prevalence was 9%. We did not find significant correlation between demographic features and impulsivity scores.
Discussion
Limits of the study: scale stability over time was not verified. This was due to the difficulty in re-inviting the same persons to fulfil the scale a second time. Because no instrument for assessing exists in Arabic, comparison was not possible between the translated Barratt's scale and the reference. Our sample represents the general population. This choice was justified in order to study an eventual correlation between impulsiveness and socio-demographic characteristics. We must mention difficulties when asking persons with low education to complete the scale, what may have caused a poorer performance of the scale due to difficulties in understanding some questions. Moreover, we had chosen a non-clinical sample. The validation of the scale could be performed in a clinical population. The measure of internal consistency (Cronbach's alpha) fell within an acceptable range (0.61-0.78), suggesting that the Arabic version of the BIS-11 is reliable. Exploratory factor analysis of the current version identified three factors, but these factors differed from those of other translated versions.
