The Normative Study of Acoustic and Aerodynamic Characteristics of Voice among Healthy Adult Turkish Speaker Population.

Phonatory Aerodynamic System (PAS Model 6600) is an evaluation instrument that assesses the effectiveness of surgical interventions, treatments, and therapy for voice disorders. It can be used for the assessment of voice disorders by supporting other perceptual and instrumental methods. It is important to establish normative data, because the use of appropriate norms is necessary for diagnostic and descriptive accuracy. Therefore, this study is aimed primarily at establishing adult normative databases for phonatory aerodynamic measures obtained with the KayPENTAX PAS Model 6600 among healthy adult Turkish speakers and then examining the effect of age, gender, and age-gender interaction variables on these measures. The contribution of the study is considered so important since it will generate normative data for all measurements-except the mean pitch-by the five protocols of PAS for the first time. Two hundred and six healthy Turkish speakers with normal voice (106 women and 100 men) were included in the study and stratified into three age groups. Forty-five phonatory aerodynamic measures across five PAS protocols (vital capacity, maximum sustained phonation, comfortable sustained phonation, variation in sound pressure level, and voicing efficiency) were collected. Age, gender, and age-gender interaction variables were analyzed for 45 PAS parameters. Significant gender and age effect was found for 30 and 19 variables, respectively. Gender-age interaction together was observed for only 6 parameters. Significant differences were not found for the remaining 10 parameters. Significant age and gender effects were observed for 35 phonatory and aerodynamic measures which are essential part of the objective clinical assessment of voice. Consequently, normative data used as reference in voice assessment should be generated according to age and gender differences.

Stuttering therapy through telepractice in Turkey: A mixed method study.

PURPOSE: The effectiveness of telepractice in stuttering therapy in Turkey may be unclear, but there is good evidence for the efficaciousness of it from other countries, e.g., Australia. The purpose of the present study is to compare the outcomes of telepractice and in-person therapy delivery on traditional stuttering treatment and explore telepractice stuttering therapy experience in Turkey. METHODS: 20 adults who stutter participated in the study. Half the participants received treatment via telepractice, while the others were provided with services in-clinic. Based on a convergent parallel mixed-method research, quantitative (Study 1) and qualitative data (Study 2) were collected in parallel, analyzed separately, and then combined. Study 1 included a non-inferiority controlled trial, repeated measures, quasiexperimental design. Within the scope of the quantitative research, the objective clinical data, including the scale and assessment scores, were collected from two groups in three stages. Study 2 used the phenomenology approach to assess the qualitative aspects of our study. RESULTS: According to the quantitative findings in Study 1, the effectiveness of telepractice and in-person in the post-test and follow up is not significantly different. The following themes emerged out of the qualitative data analysis in Study 2: expectation, telepractice-participant suitability and advantages of telepractice, technology, therapy techniques and clinician skills, therapeutic components, satisfaction, and preference. CONCLUSION: The triangulation of quantitative and qualitative findings indicated that these data sets were compatible in general. The results show that telepractice is equally effective as the in-person method as a service delivery method for adults who stutter.

Stroke and aphasia quality-of-life scale-39: Reliability and validity of the Turkish version.

PURPOSE: The aim of this study was to adapt the stroke and aphasia quality-of-life scale-39 (SAQoL-39) to the Turkish language and carry out a reliability and validity study of the instrument in a group of patients with aphasia. METHOD: The study was a descriptive study and contained three phases: adaptation of the SAQoL-39 to the Turkish language, administration of the scale to 30 aphasia patients and reliability and validity studies of the scale. Internal consistency was assessed with Cronbach's alpha and test-re-test reliability was explored (n = 14). The adaptation process was completed based on inter-rater agreement on the translated items and within the scope of final editing by the authors of the study. RESULT: The SAQoL-39 in Turkish exhibited high test-re-test reliability (ICC =0.97) as well as acceptability with minimal missing data (0-1.4). This instrument exhibited high internal consistency (Cronbach's α = 0.70-0.97), domain-total correlations (r = 0.76-0.85) and inter-domain correlations (r = 0.40-0.68). CONCLUSION: The analysis shows that the Turkish version of SAQoL-39 is a scale that is highly acceptable, valid and reliable and can be easily used in evaluating the quality-of-life of Turkish people with aphasia.

How do families of children with Down syndrome perceive speech intelligibility in Turkey?

Childhood verbal apraxia has not been identified or treated sufficiently in children with Down syndrome but recent research has documented that symptoms of childhood verbal apraxia can be found in children with Down syndrome. But, it is not routinely diagnosed in this population. There is neither an assessment tool in Turkish nor any research on childhood verbal apraxia although there is a demand not only for children with Down syndrome but also for normally developing children. The study examined if it was possible to determine oral-motor difficulties and childhood verbal apraxia features in children with Down syndrome through a survey. The survey was a parental report measure. There were 329 surveys received. Results indicated that only 5.6% of children with Down syndrome were diagnosed with apraxia, even though many of the subject children displayed clinical features of childhood verbal apraxia. The most frequently reported symptoms of childhood verbal apraxia in literature were displayed by the children with Down syndrome in the study. Parents could identify childhood verbal apraxia symptoms using parent survey. This finding suggests that the survey can be developed that could serve as a screening tool for a possible childhood verbal apraxia diagnosis in Turkey.

Attitudes of Turkish speech and language therapists toward stuttering.

PURPOSE: The study sought to identify clinical beliefs and attitudes of speech and language therapists (SLTs) in Turkey and to compare them to previous research on SLTs in the USA and UK. METHOD: The Clinician Attitudes Toward Stuttering (CATS) inventory was administered by mail to nearly all-practicing SLTs in Turkey (n=61). RESULTS: Turkish SLTs, whose caseloads contained a substantial number of people who stutter, agreed with CATS items suggesting psychological causes and problems for those who stutter. They strongly believed therapy should focus on parent counseling for preschoolers who stutter as well as adolescents. They were not optimistic about carrying out stuttering therapy nor about the likelihood that children who stutter could be effectively treated. CONCLUSION: Attitudes toward stuttering by clinicians who treat them are important considerations in the conduct and outcomes of stuttering therapy. Additionally, SLTs working with stuttering clients should benefit from professional views and clinical experiences of their colleagues from surveys such as this one. EDUCATIONAL OBJECTIVES: The reader will be able to describe: (a) the components of the CATS, (b) common themes in Turkish speech and language therapists' attitudes toward stuttering, (c) differences between the attitudes of speech and language therapists from Turkey versus the United States and the United Kingdom.
