Impulsiveness refers to the state of mind in which one makes decisions without much thinking. A good example of this is an impulse buy (buying something you later realise you do not really need).

Of course, some level of impulsiveness is normal in children and adults, after all, we make many decisions quickly and automatically. That said, there is variability in the level of impulsiveness, and that is exactly what tests such as the DSIS-C measure.

The ISC (Tsukayama, Duckworth, & Kim, 2013) distinguishes between impulsivity in different domains, namely interpersonal and schoolwork related impulsivity.

In a study with 453 children (mean age 12.5 years), the average scores were as follows1:

Scale Average score (on a range from 1-5) Standard Deviation

Overall score



Schoolwork impulsivity score



Interpersonal impulsivity score

The DSIS-C can be used for research, but you need to acknowledge the authors and their research paper when writing about it (Tsukayama, Duckworth, & Kim, 2013).


This is a simple scale question.
