Validation of the Dutch translation of the I7 questionnaire

The Impulsiveness-Venturesomeness-Empathy questionnaire (I7) is a frequently used questionnaire assessing aspects of impulsivity. Since a Dutch translation is lacking, comparisons and inferences regarding these traits are limited between results from studies that do use the I7. We translated the I7 and studied the psychometric properties in a Dutch sample of 1048 students between 16 and 59 years of age. The results are consistent with those found in English, French, German, Spanish, and Swiss samples. That is, three orthogonal factors were extracted that are highly congruent between genders and with the English normative sample. Furthermore, scale inter-correlations and reliabilities were also similar to previous results. This implies that the Dutch translation of the I7 questionnaire is suitable to assess impulsivity and venturesomeness in Dutch-speaking countries, and to differentiate between these traits.
