Do you have access to a large database of articles, like from a university, or were you just drawing from open source material, like PLOS? Nothing against open source or PLOS, just wondering which wells you’ve already tapped. Stuttering/dysfluency textbooks for SLPs are a good start. I’d recommend contacting the authors directly. They’re usually more than happy to share their own research or point you in the right direction. Some authors: Logan, Eggers, and Yaruss (he’s one of the big ones). Here’s a link to the ASHA page about stuttering. You’ve probably already seen it, but just in case… [ASHA Link](https://www.asha.org/practice-portal/clinical-topics/fluency-disorders/) Hope that helps a bit!
