Yes, I see what you mean--I will admit that I am not as well-versed in computational algorithms compared to counselling/mental health.

The closest hit in the study is: " We computed the semantic distance using an algorithm called GloVe (35), which has previously been used to score the Alternative Uses Task (26, 27). "

I also see a GitHub link in the study--I'm not sure if this site will let me post that link.
