Theoretical background
The DII is a self-report measure of impulsivity (23 items) that consists of two scales: Functional impulsivity (11 items), and Dysfunctional impulsivity (12 items). The original version of the DII used a dichotomous response format, but in the Portuguese validation study (20 items) we adopted a four-point format (0 = Totally false, 1 = In part false, 2 = In part true, 3 = Totally true). Items are summed to create each scale. Higher scores indicate higher levels of functional and dysfunctional impulsivity characteristics.
Description
Assessment Domain: Impulsivity.
