Title of Study Primary Researcher Contact Approved by NSA Research Committee until: Abstract
Voluntary Stuttering Jason Davidow & Heather Grossman jason.davidow@hofstra.edu 04/18/2012 This study explores the impact of differing amounts of bouncing (purposeful repetitions of sounds and/or syllables) on stuttering frequency, speech effort, and speech naturalness. Fifteen adults who stutter will complete a series of oral reading tasks involving various amounts of bounced sounds and/or syllables. The experimental protocol will be completed in one day and last approximately 1 ½ hours. Experimental activities will be conducted in the Adult Research Laboratory in Davison Hall at Hofstra University, or at a quiet location convenient for the participant. Participants will be compensated for their time. For more information, or if you would like to participate, please contact Jason H. Davidow at jason.davidow@hofstra.edu, or call 516-463-4582.
Survey About a New (High Tech) Fluency Device Tyler Hagler jthagler@ncsu.edu  03/29/2012 NC State Researchers Need People Who Stutter and SLPs to Participate Survey About a New (High Tech) Fluency Device

A team of graduate students from the NC State University are evaluating a fluency device invented in the Product Innovation Lab last semester. They are seeking people who stutter and Speech-Language Pathologists to take the survey to understand whether the device would be valuable to the stuttering community. The survey for both people who stutter and SLP’s.

If you do wish to contact the graduate student group with questions about the survey or their project, please feel free to call or email Ty Hagler at 919-724-2439 or jthagler@ncsu.edu

We'll be sure to send a copy of the research results and to acknowledge NSA in our final presentation.

 

Phonological skills of adults who stutter Kristin M. Pelczarski kpelczarski@gmail.com 02/07/2012 My research investigates some of the language factors that may be involved in stuttering. I am currently recruiting for a study that investigates the phonological processing skills of adults who stutter as compared to adults who do not stutter.

We are looking for both people who stutter and people who do not stutter age 21-50. Aside from stuttering exhibited by the adults who stutter, participants will be required to have no known hearing, language or neurological difficulties. For the purposes of this study, we can only include people for whom English is the first and only fluent language.

Participants will be asked to complete a battery of tests that require an individual to answer questions or perform verbal tasks to determine phonological processing skills and vocabulary skills. These tests take approximately 2 hours to complete (but can sometimes take as long as 2 1/2 hours). Participants will be paid $15 as compensation for participation.

If you are interested in helping us learn more about stuttering and would like to participate, please contact Kristin either by email (kpelczarski@gmail.com) or by phone (412-260-1588).

 

Speech-language pathologist knowledge of support groups

Behnaz Abolmaali &

Courtney Byrd
behnazutx@gmail.com 1/14/2012 Support groups such as the National Stuttering Association have become an important part of treatment and recovery process for many people who stutter. However, these groups are still undervalued among many speech-language pathologists. In an effort to better understand the dynamic of the relationship between support groups and SLPs, and how it may lead to more effective support groups, SLPs – both those who participate in the NSA and those who do not – will be surveyed about their opinions regarding self-help for stuttering.

It is hypothesized that a majority of SLPs – even those who work with clients who stutter – will have little or no direct experience with stuttering support groups. It is further hypothesized that those who do participate will experience a number of benefits, including increased knowledge of stuttering, and enhanced competence working with clients who stutter.

The study will attempt to answer the following research questions:

1) How knowledgeable are SLPs about support group resources for people who stutter?
2) How often and under what circumstances do SLPS refer clients who stutter to support groups?
3) What benefits do SLPs derive form their participation in support groups for people who stutter?
4) In what capacity do SLPs prefer to participate in support groups?
 

Parents of Children and Adolescents Who Stutter:  A Mixed-Model Investigation of Knowledge, Perceptions, and Experiences Derek E. Daniels dedaniels@wayne.edu 01/14/2012 The purposes of this study are to investigate knowledge and perceptions of stuttering, and personal experiences of parents and primary caregivers of children and adolescents who stutter. The specific aims are as follows: (1) To empirically confirm and explore the ways in which parents of children and adolescents who stutter manage their own emotions and experiences; (2) to develop a deeper understanding of the different ways in which parents cope with having a child or adolescent who stutters; (3) and to facilitate more effective counseling strategies for speech-language pathologists who work with parents of children and adolescents who stutter.

Sexual dimorphism of neural development underlying childhood stuttering Soo Eun Chang schang7@msu.edu 11/16/2011 Researchers at the Michigan State University are conducting an NIH-funded, 5-year longitudinal investigation to study brain development in boys and girls who stutter.

The overall objective of this research is to identify structural and functional neural markers of stuttering close to symptom onset and determine gender-specific brain developmental trajectory markers that serve to differentiate those children who do or do not recover from stuttering. The results of this study are expected to help clarify the neural bases of childhood stuttering, and lead to development of novel treatment options for stuttering.

We are recruiting children who have been stuttering for more than 6 months, in the 4-8 year-range, to participate in comprehensive speech-language-hearing testing, cognitive and sensorimotor testing, and MRI scanning of the brain. All procedures are non-invasive and have been approved by the MSU IRB and the NIH. Children will be able to take home a picture of their brain, and parents will be given a comprehensive report of the assessments. All expenses for travel to the MSU campus in East Lansing will be reimbursed and families will be compensated for the time they spend in participating in the studies.

The National Stuttering Association and Friends, The Association of Young People Who Stutter, are conducting a survey on the experience of children, teens and young adults who stutter. If you work with children who stutter, we will appreciate your help in letting their parents know about this survey and inviting them to participate. Your teen and young adult clients may participate in the survey as well.

The online questionnaire asks about the impact of stuttering on the lives of children, and about their experience with stuttering treatment and support groups. The survey includes questions specifically directed at parents as well as teens and young adults who stutter.

If you wish to look at the questionnaire yourself, you may preview it by clicking on this link or pasting it into your browser: http://www.surveymonkey.com/s/38KK955

Parents and teens may begin the questionnaire by clicking on this link or pasting it into their browsers: http://www.surveymonkey.com/s/QX6H6RF

The survey should take about 15 minutes to complete. Individual responses are confidential, and will be combined with other responses for statistical results. Survey findings will be posted on both the NSA and Friends web sites.

The survey findings will be used to educate the public about stuttering, and to give speech professionals greater insight into the issues faced by children and teens who stutter and their parents.

University of Maryland neuroimaging study of stuttering  Joshua Riley  jriley1@umd.edu  06/29/2010  

The Language Section of the National Institute on Deafness and Communication Disorders is recruiting participants who stutter for a behavioral and functional magnetic resonance imaging (fMRI) study of anticipation in stuttering. Many people who stutter report that they have had the experience of predicting when they are going to have problems speaking. We want to find out exactly how often this happens, and how accurate these predictions are. We also want to know what brain regions are involved in making these predictions, and how similar these regions are to those that are active when dysfluencies are occurring.

To do this, we want to use fMRI to perform brain scans of people who stutter while they are performing a few speech tasks, like reading selected passages and having a conversation with an experimenter. All the while, we will be asking our participants to indicate when they think they are about to have trouble speaking.  This will test a major theory about why stuttering happens, and will tell us more about the neurology of stuttering.

Participants can take part in this study at either the main campus of the National Institutes of Health in Bethesda, Maryland, or at the University of Maryland, College Park (both Metro-accessible). Participants can choose to take part in just the behavioral testing portion of the study, or the whole study, including fMRI. Participants will be compensated for their time.

For more information or if you are interested in participating, please contact Joshua Riley at jriley1@umd.edu.
 Beliefs and attitudes of children and adults who stutter regarding their ability to overcome stuttering  Kenneth Melnick  kmelnick@worcester.edu  06/29/2011  

The purpose of this study is to determine how children and adults who stutter perceive their ability to overcome stuttering.  Participants will be monolingual Standard American English speaking males and females who exhibit stuttering in the age range 8 years old through adult.  Participants are required to travel to Worcester State College, Worcester, MA for one evaluation session that will last approximately 45 minutes.  The evaluation will include stuttering behaviors and attitudes as well as computerized questionnaire for mindset of stuttering.  There is no cost to participate; in fact, participants will received a $20.00 gift card to Target at the conclusion of the evaluation.  Please contact me if you would like to learn more about my study or be a participant:  kmelnick@worcester.edu or (508) 929-8836.  Thank you!

 Relationship between severity of stuttering and quality of life in adults who stutter  Brandy Combs  brandy_combs45@eku.edu  06/02/2011  

You are being invited to take part in a research study about the relationship between severity of stuttering in adults and their perceptions of quality of life. The purpose of this study is to determine if there is a statistically significant relationship between severity of stuttering and quality of life. We hope to learn about this relationship by comparing the scores of people who stutter on the Stuttering Severity Instrument-4th edition (SSI-4; Riley, 1994), the Medical Outcomes Study Short Form (SF-36; Ware, 1993), and the Overall Assessment of the Speaker’s Experience of Stuttering (OASES; Yaruss & Quesal, 2008) for adults who stutter (AWS).

Participants should be in the age range of 18 to 65 years, have previously sought treatment for stuttering, and in generally good health.

If you decide to take part in the study, it should be because you really want to volunteer. You will not lose any benefits or rights you would normally have if you choose not to volunteer. You can stop at any time during the study and still keep the benefits and rights you had before volunteering.

If you have any difficulties, questions, or concerns regarding this study, please contact me at:

 Cognitive-linguistic processing in word production in adults who stutter  Pei-Tzu Tsai  ptsai1@umd.edu  05/18/2011  

The purpose of this study is to examine the influence of processing demand on production in adults who stutter (AWS). Evidence for language-related processing difficulties in AWS is emerging, yet inconclusive about the specific linguistic processes that might relate to fluency breakdown. It is possible that not all tasks are sensitive in reflecting subtle difficulties in online linguistic processing. This study will examine selected processes of word production under varying levels of processing demand. The goal of the study is to determine if there is deficiency at specific levels of linguistic processing during production and how processing demand affect production performances in adults who do and do not stutter.

 

We welcome individuals who are 1) native English speakers, 2) over 18 years old, 3) diagnosed with developmental stuttering, 4) have normal or corrected vision, and 5) no other communication disorders.

 

Eligible participants will receive stuttering, language, hearing and cognitive assessments, and complete word production tasks, in a two-hour session. Findings will be shared with participants. Please feel free to contact Pei-Tzu Tsai (ptsai1@umd.edu) with any questions or concerns.
