Hello, I am a graduate student studying to be an SLP. I have a question question for anyone who may be involved with or understands research in the area of stuttering. After reviewing some research in this area, I began to wonder about the challenges of selecting participants, sample characteristics, and exclusionary criteria when conducting a study. Considering the many factors that may affect the persistence and development of stuttering (e.g., sex, cognitive status, environmental factors, etc.), it seems like controlling for these factors could be a very difficult matter. The outcomes of each person can be so individualized due to the flexible, multifactorial, and highly individualized nature of stuttering. My question is, how do researchers in stuttering typically navigate this challenge? Do they include a lot of exclusion criteria? Do they try to limit the exclusion criteria to try and make the participants as representative of the population of people who stutter overall? Thank you for your time!
