Cultural diversity and fluency disorders

Chapter 9 Cultural diversity and fluency disorders



The relevance of cultural and international factors in the assessment and treatment of communication disorders has been discussed in the literature (Battle, 1997; Guitar, 2006; Taylor, 1986; Terrell & Hale, 1992; Proctor et al., 2008). Essentially, the relevance is, in order for assessment to be accurate and meaningful and for treatment to be maximally effective, both should be conducted with regard to the client’s cultural identity, cultural assimilation, cultural environment, and cultural system (Crowe et al., 2000; Robinson & Crowe, 1998). Clinicians and researchers have attempted to address this issue by providing models for service delivery in various clinical settings and with various cultures (Robinson & Crowe, 1994; Robinson & Crowe, 1998; Seymour, 1986; Seymour & Seymour, 1977; Taylor, 1986; Taylor & Payne, 1983; Taylor & Samara, 1985; Van Kleeck, 1994; Vaughn-Cooke, 1983, 1986). These models, for the most part, have been discussed relative to nonbiased assessment of speech articulation disorders, with little reference to the treatment process.


Attention has been given to the influence of cultural factors on the evaluation and treatment of stuttering (Bullen, 1945; Cooper & Cooper, 1993; Crowe et al., 2000; Robinson & Crowe, 2000, Watson & Kayser, 1994). Consideration of cultural variables should begin when clients or their families first contact clinical centers to schedule evaluations or merely to obtain information. Clinical intervention for treatment of stuttering should be structured within the context of each client’s cultural system and cultural environment. After determining the client’s cultural identity and degree of assimilation into the culture, in order for therapy to be maximally effective and also for therapy to be efficient in regard to time spent setting and achieving goals. Clinicians’ attention to these cultural dimensions of the therapy relationship also will increase the probability that counseling for the prevention of stuttering will be effective (Crowe, 1995).


Cultural system pertains to all that composes the belief systems of clients. This includes values, attitudes, perceptions, myths, and so on, and to a large extent these culture-based factors determine the perceived reality in which clients operate. The client’s perceptions of reality may or may not match the clinician’s; if their perceptions do not match, there is likelihood that intervention, and especially counseling, will not be maximally effective. Of course, cultural variables account for only one of the reasons that a client and clinician’s phenomenal field may not match, but different cultural systems is a frequent reason why they do not. Phenomenal field in this context refers to the comprehensive experiences and belief systems of individuals.


Cultural environment is also important to take into consideration when structuring a plan for counseling in fluency intervention. This includes all aspects of the client’s environment: his or her phenomenal field; access to experience; semantic environment; relationships with significant others; and language environment. In the case of child clients, it is important for clinicians to remember that parents are the chief architects of their child’s environment and should be counseled to be active in designing an environmental gestalt for their child that is conducive to speech fluency and to normal personality development (Crowe, 1994). The environment of the child with disfluencies should be conducive to him or her developing the use of ego functions that might in turn help prevent the development of defensive reactions to speech disfluency and to speech therapy.


A general model for inclusion of these cultural factors in assessment and therapy planning for individuals who stutter is discussed later in this chapter. Also discussed later are techniques for identifying aspects of the client’s cultural identity, cultural assimilation, cultural environment, and cultural system as well as the influence of culture on beliefs and behavior related to stuttering.



Universality of fluency disorders


Like most disorders that affect the human condition, fluency disorders, in specific stuttering, are not restrained by geographic demarcations. Stuttering appears on every continent, in every country, in every corner of the globe. The evidence for the universality of stuttering is summarized effectively by Van Riper (1982), Bloodstein (1995), and Bloodstein and Bernstein Ratner (2008).


The universality of stuttering pertains to cultures as well as continents and countries. There is strong evidence that stuttering appears in all cultures, or to put it more conservatively, there is no compelling evidence for any culture that indicates stuttering does exist within it.


Cultural groups that have been studied include Native Americans (Clifford et al., 1965; Johnson, 1944a, 1944b; Lemert, 1953; Snidecor, 1947; Stewart, 1960; Zimmerman et al., 1983), African Americans (Anderson, 1981; Brutten & Miller, 1988; Conrad, 1985; Ford, 1986; Goldman, 1967; Leith & Mims, 1975; Nathanson, 1969; Proctor et al., 2008; Robinson, 1992; Robinson & Crowe, 1987, 1998; Robinson et al., 2000), Asians (Lemert, 1962; Toyoda, 1959; Wakaba, 1983), Hispanics (Bernstein-Ratner & Benitez, 1985; Dale, 1977; Jayaram, 1983; Nwokah, 1988; Travis et al., 1981), West Indies (Ralston, 1981); and African (Aron, 1962; Goodall & Brobby, 1982; Kirk, 1977; Morgenstern, 1953, 1956; Nwokah, 1988). Results of these studies generally suggest that cultural differences influence speech fluency and that there are differences in perceptions, beliefs, values, and norms about speech fluency and fluency disorders among various cultural groups. One possible significance of these suggestions is that cultural factors might appreciably affect the outcomes of clinical intervention with fluency disorders.


There has been disputation about the universality of stuttering with argument that it is not universal based on sparse, largely anecdotal data that for the most part were later refuted. The best known case of this was the assertion by Johnson (1944) and two of his students, Snidecor (1947) and Stewart (1960), that stuttering did not exist in the Utes, Bannock, and Shoshone American Indian tribes. This idea was on the researchers’ findings that no stuttering was reported in interviews with numbers of the tribes, social pressures on communication appeared to be minimal within the tribes, and no word in the tribal languages could be found for stuttering. Evidence was later presented (Zimmerman, 1983) that stuttering does exist in these American Indian tribes.



Prevalence of stuttering among cultures


Although the idea that in some cultures stuttering may not exist is given little credence today. The thought associated with it that social demand on communication and stuttering might be positively correlated may be one possible explanation for varying prevalence among cultures. Cooper and Cooper (1998) stated that “universally accepted definitions do not exist regarding what constitutes the fluency disorders that the English terms stuttering and stammering and their equivalents in other languages have come to encompass and symbolize” (pp. 252-253). They also pointed to a great deal of variability in the data collection process across cultures. Van Riper (1982) and Bloodstein (1995) indicated that the prevalence of stuttering in the general population is about 0.8%, whereas the incidence of stuttering in some cultural groups is between 5% and 10%. Tables 9-1 through 9-5 depict prevalence research in various cultural groups.

Factors that influence stuttering in cultural groups


Researchers have reported a number of factors that may influence all aspects of speech and language. Some of these factors have been discussed earlier in this text and have been highlighted over the years by researchers and scholars as having great impact on the service delivery to clients and their families. Specific to the area of stuttering, such influences have been linked to attitudes, myths and beliefs, religion, nonverbal behaviors, and events in the life cycle.








A culture-based model


Robinson and Crowe (1998) presented a decision model for inclusion of multicultural variables in stuttering intervention. In this model, six levels are presented: preintervention; intake; evaluation; client counseling; treatment; and carryover or generalization. Decisions are made at each intervention level as to the relevance of cultural variables in the intervention process. At each level, the decision is also made whether to revisit previous levels or to expedite progress through a given level.
