Dear Thu Van, thank you for your question!
Basically, everyone could profit from it.
My main focus was on people with language comprehension problems. These could be adults with special impairments (for example dyslexia), children who don’t have a big vocabulary and are not able of abstract thinking and even foreigners, that don’t speak the language very well. They could profit from it by not having to fill out questionnaires which they have problems of even understanding properly.
But I also think that non impaired adults could have a gain from pictorial questionnaires. As earlier studies on pictorial questionnaires and even your study demonstrated, pictorial questionnaires are a lot more fun to fill in. Due to the colourful and non monotone design they are more aesthetically pleasing. So if someone is not very keen on filling out boring questionnaires, this could make a change on their mindset.
