This risk protocol is part of the book "Diagnóstico e Intervenção Precoce nas Gagueiras Infantis" (Stuttering in children: early intervention). It is already being used in Brazil with excellent results. The Investigation Laboratory of Fluency and Fluency Disorders has received SLP and given training for the application of the protocol. This is the experience we would like to share with our ISAD Conference colleagues in this year of 2000.

This paper proposes the application of a screening protocol for the identification of the stuttering risk level in children; from its onset to its development into chronic disfluency. This protocol is based on recent studies about risk factors which may lead to the onset and development of stuttering during childhood.
The concept of stuttering in children is extremely controversial. As pointed by Yairi and Ambrose (1992) although it is difficult to determine exactly how and when disfluencies appear, the disorder is only noticed when certain changes in the childs speech are considered to be a problem. Speech is marked by hesitations, repetitions, stops and other interruptions, followed or not by physical effort.
For children, as pointed by Zebrowski (1995), during the years of language development and acquisition, the existence of fluctuations in speech fluency is normal. This variation results from syntactic and semantic uncertainties and from the neuromotor maturation for speech queues. Most children surpass this period with success - almost 75% of the children recover the fluent speech pattern in 6 to 8 months after the beginning of repetitions. For the other group, disfluency remains or aggravates being followed or not by body movements. This group has a high probability of becoming chronic (Curlee and Yairi, 1997). Recognizing these children at an early stage will increase the chances of intercepting the diseases evolutive process.
Although precise epidemiological studies on stuttering do not exist, a few authors like Yairi (1997); Curlee and Yairi (1997), Gregory (1984), Perkins (1992), Rustin and Purser (1991) bring relevant points such as: incidence is of 4 to 5% for the overall population and prevalence is of 1%. The disorder is found in the majority of cultures and natural languages; it is more frequent in males (3.5/1); a high index of spontaneous recovery exists, especially during childhood; 20 to 30% of disfluent children become stutterers; its distribution per age of onset is of 27% until 3 years, 68% until 3 to 7 years and 5% above 7 years.
As pointed by Smith (1990) and Craig (1994), the available evidence about the nature of stuttering suggest that it is a pathology deriving form a neuromotor deficit, which in turn creates a psychological response and has an impact on social adjustment. Although an agreement about stuttering etiological factors does not exist, certain interrelated predisponents - heredity, biological, psychological, linguistic and social factors - answer for the development of the disorder.
About heredity, based on researches and studies of Andrews and Harris (1964), Kidd (1983), Cox, Seider and Kidd (1984), Poulos and Webster (1991), Yairi and Ambrose (1992), it is known that family predisposition cannot be disregarded as a precipitant factor for the disease.
The nature of the relationship between fluency, stuttering and language formulation has been the focus of attention of several researchers (Throneburg et al., 1994; Ratner, 1995; Stager and Ludlow, 1993; Louko, 1995; Hill, 1995). In a linguistic context, elements which have large impact on speech fluency are: deficits in articulation and/or phonology acquisition and/or development; deficits in language acquisition and/or development, in terms of extension and complexity, overall syntatic-semantic-pragmatic aspects; learning difficulties, specially in reading acquisition and/or development; increased articulatory pressure; increased speech rate.
One of the greatest paradigms involving the study of stuttering is the influence of the environment, in particular the behavior and attitudes, linguistic and paralinguistic, of parents and other speakers (teachers, friends, etc) who are close to the child. The importance of family interactions, as a fundamental factor for the onset and development of stuttering , has been largely defended since the 40s with the studies of Johnson, and is still studied until the present day (Kelly and Conture, 1992; Onslow et al., 1992; Zebrowski and Conture, 1989; Botterill et al., 1991; Conture and Kelly, 1991).
For the planning of an efficient early intervention program (Curlee and Yairi, 1997; Zebrowski, 1997; Ratner, 1997; Hill, 1997; Andrade, 1997 a/b), compromised elements of every area and how they interrelate should be investigated, selecting which are more relevant and verifying how the development in terms of severity occurs. Basic elements to be taken into consideration are: age, sex, disfluency type, time of onset, type of onset, related communicative factors, related qualitative factors, psychological factors, morbid pre-peri-post natal background, family background and the reaction of family members, the child itself and environment towards disfluency.
The protocol is composed by 15 questions and should be used with the child´s parents or guardians. After all the questions have been answered, each column has their points added, giving the therapist an idea of the child´s condition.
Screenings are by definition simple procedures; easy to use; low in cost and have a good discriminating response. The aim of a speech and language screening is to detect a communication disorder in its early stages. The early detection of a speech and language disorder will in turn allow the use of procedures which will make treatment most effective (Andrade, 1996). It is important to have in mind that screening by itself will not bring any benefits to health. It is an act of prevention that simply identifies who has certain risk conditions to develop a disorder or who will benefit from immediate treatment.
The concept of risk, as pointed by Ayres (1997), implies in the delimitation of susceptibility, attributable to an individual or to a group in the population, determined by the exposure to specific agents (aggressors or protectors). To determine what is considered to be of risk depends on the already established knowledge about the natural history and distribution among the population of a certain disorder. Therefore, the first point to be taken into consideration in this process is that data obtained in screenings and speech and language assessments are clearly insufficient for the early detection of risk to develop chronic stuttering.
In this way, with the use of the proposed protocol - incorporated to everyday speech and language assessment material or adapted for screenings in the population - the speech pathologist will be equipped to proceed safely in the intervention of stuttering. The obtained results will allow the identification of the childs risk level to develop stuttering and will help in the selection of the most appropriate treatment according to each case.
STUTTERING RISK PROTOCOL
The filling in of the protocol must follow the sequence shown above, marking the correspondent column with the number o points discriminated below. After completing the questionnaire, the points corresponding to each column must be added, identifying the area with more points.
Hesitation: silent pause of one to two seconds of duration where the child seems to be looking for a word.
Interjection: inclusion of meaningless words or phrases irrelevant to the conveyed message ( well, uh, um, you know, like ).
Revision: a change in content of the conveyed message, grammatical form or pronunciation of a word ( can he she come over ? he tooked took it to the teacher ).
Unfinished word: a word which is abandoned, not completed later in the current unrevised message. Unfinished words are typically followed by revisions ( Sally wants choc vanilla ice-cream ), on occasion, the conveyed message is continued without being revised ( We went to Flori for vacation ).
Phrase repetition: the repetition of at least two complete words of the conveyed message ( Its a beautiful a beautiful day ).
Word repetition: the repetition of a whole word including single syllable words ( What time time is it? I need a a pen ).
Syllable repetition: more than a sound repetition and less than a word repetition. Any part word repetition is included ( I want the ba ba banana. The ambulance lance passed us ).
Sound repetition: repetition of a phoneme or an element of a diphthong that does not stand alone as a word ( Do you want s s s some coffee ? ).
Prolongation: inappropriate duration of a phoneme or an element of a diphthong which may or may not be accompanied by qualitative characteristics such as pitch change, increased audible tension or visible tension ( Th_____ ats mine. Can I have a_____ piece of cake? ).
Block: inappropriate timing in the initiation of any phoneme or the release of a stop element, usually accompanied by increased audible tension, visible tension or fixed articulatory posture ( mouth open before speaking or facial tremors before speaking etc. ).
Pause: inappropriate pause, interrupting the temporal sequence of speech ( more than 3 seconds to connect the elements ). Can be accompanied or not by qualitative characteristics.
Criteria for selecting which therapeutic program the child will enter: add all the points in each column. The column that shows the greater number of points will correspond to the therapeutic program in which the child should take part. If by any chance there are columns with equal number of points, the child should enter in the more complex program.
