RESUMEN

INTRODUCTION: The quick aphasia battery (QAB), which assesses all areas of language in detail and quickly, was developed in English. It has been shown to be suitable for bedside patients. There is a need for a Turkish bedside test that allows for a comprehensive yet rapid assessment of stroke patients in terms of aphasia. The aim of this study was to create a Turkish version of QAB (QAB-TR) and to determine its validity and reliability in Turkish-speaking patients after a stroke. MATERIALS AND METHODS: The study was conducted with 188 people aged 41-88 years. Of these, 37 (19.7%) had aphasia (12 chronic, 25 acute), 53 (28.2%) were acute stroke patients without aphasia, and 98 (52.1%) were healthy controls. Internal consistency and criterion validity, test-retest reliability, and inter-rater reliability of the QAB-TR were performed. The language assessment test for aphasia was used for criterion validity. For the inter-rater reliability of the test, two different speech language therapists (SLP) administered the QAB-TR. For test-retest reliability, 2 weeks later, the same SLP who filled out the QAB-TR the first time was administered the test again. To test the validity of the test, correlations between the items and subsections were determined. Receiver operating characteristic (ROC) analysis was performed to examine the sensitivity and selectivity of the QAB-TR score, and a cut-off value was determined to distinguish patients with aphasia. RESULTS: The inter-rater Krippendorff's alpha value of the QAB-TR total was 0.6754. There was no statistically significant difference (p > .05) between the first and second QAB-TR total scores. The correlation analysis between the QAB-TR subsection scores and the total QAB-TR score (0.244-0.897) revealed statistically significant relationships. The area under the ROC curve was statistically significant and was found to be 0.853 (95% confidence interval: 0.799-0.906). The cut-off point for the QAB score to discriminate between patients with aphasia and those without aphasia was found to be 8.825, with 0.767 sensitivity and 0.765 selectivity (1-0.235). CONCLUSION: All the study results show that QAB-TR has internal consistency, criterion validity, test-retest reliability, and inter-rater reliability. It can be administered in as little as 15 min and provides information about the multidimensional linguistic profiles of individuals. QAB-TR can be used for both clinical and study purposes as a language battery that allows for the measurement of the strengths and weaknesses of Turkish-speaking individuals who have suffered a stroke in basic language areas in acute and chronic periods. It can be easily administered at the bedside for individuals who have just suffered an acute stroke and can facilitate early assessment of individuals in terms of aphasia and early initiation of therapy, if necessary.

RESUMEN

BACKGROUND: Alzheimer's disease (AD) is a progressive neurodegenerative disease. Cognitive functions and communication skills worsen as the disease progresses, thereby reducing patients' independence levels. Therefore, recommending software that can be used at home may be a useful means of slowing down the cognitive and communicative decline in AD. AIMS: To develop software that can be used at home to slow down the cognitive and communicative decline and increase independence in individuals with AD; and to examine the effect of this software on the cognitive communication skills of individuals with AD. METHODS & PROCEDURES: The study was completed in four stages: the development of the application; the evaluation of the participants and their training for the application; their use of the application at home; and the re-evaluation of the participants. A total of 32 individuals who met the inclusion criteria were included in the study. These individuals were randomly divided into study and control groups, each consisting of a total of 16 participants, including six in the mild stage, six in the moderate stage, and four in the severe stages. The developed software was loaded on tablets and given to the participants in the study group. The participants in the control group only received their pharmacological treatment, while those in the study group received both their pharmacological treatment and used the developed application. All participants were evaluated with the Mini-Mental State Examination (MMSE) and Language Assessment Test for Aphasia (LATA) before and after application use. A survey was administered to the caregivers of the participants in the study group after the use of the application. OUTCOMES & RESULTS: The results revealed a positive change in the cognitive-communication skills of the individuals in the study group, even if they were in the severe stage, according to the LATA and MMSE, as well as the survey. The application led to the greatest improvements in grammar on the LATA and orientation on the MMSE. No rapid cognitive decline was seen in individuals at all stages in the control group. CONCLUSIONS & IMPLICATIONS: In this study, software was developed in Turkish that can be used in every stage of AD as part of a holistic cognitive-communication intervention programme offering alternative and supportive communication for individuals with AD, even those in the severe stage. Results prove the effectiveness of the developed software on the cognitive-communication skills of individuals with AD. WHAT THIS PAPER ADDS: What is already known on the subject There are a few (as far as is known, three) applications developed in English for cognitive-communication disorders due to dementia. What this study adds to the existing literature In this study, for the first time in Turkish, mobile-compatible software has been developed for both cognitive and communication disorders that is specific to individuals with AD and can be used by individuals at all stages of the disease. The effects of the application we developed on the cognitive-communication skills of individuals with AD were shown in a randomised controlled trial. What are the potential or actual clinical implications of this work? Using the app can help people with all stages of AD keep their cognitive and communication skills and have a better prognosis in terms of cognitive-communication skills, especially grammar and orientation.

RESUMEN

OBJECTIVES: The advantages of cepstral measurements in the evaluation of dysphonia have been noted in previous studies. However, there is an unclarity regarding the results of cepstral analyzes effect in determining the severity of dysphonia. The aims of this study were to determine the cut-off values of cepstral peak prominence, cepstral peak prominence standard deviation, low frequency/ high frequency ratio, low frequency/high frequency ratio standard deviation, and cepstral spectral index of dysphonia for predicting the voice severity within a Turkish speaking population, as well as to confirm the discriminative power of these cut-off values. MATERIALS METHODS: One hundred ninety-five individuals with voice disorders and an equal number of age and gender-matched individuals without voice disorders were included. Included subjects had visited the Hacettepe University Hospitals Speech and Language Therapy Department for voice evaluation between January 2017 and September 2021. The voice recordings from all participants included the six CAPE-V/Turkish sentences and sustained vowel /a/. Three raters provided auditory perceptual ratings of the voice samples using the GRBAS scale (grade) and overall severity for the CAPE-V/Turkish. Participants were categorized into normal and mild, moderate, and severely dysphonic groups based on the auditory perceptual evaluation. Analysis of Dysphonia in Speech and Voice (ADSV) software was used for cepstral spectral acoustic analysis. RESULTS: In the sustained vowel context, the area under the curve (ROC) for the CSID value was >0.8, except for mild vs. moderate dysphonia groups. In connected speech contexts, the ROC of the CPP value was also >0.8, except for normal vs. mild dysphonia groups. The cut-off values of CPP and CSID demonstrated high sensitivity and specificity for predicting voice severities. CONCLUSION: The cut-off values for the parameters that predicted voice severities showed a significant degree of discriminative power for categorizing voice severities among Turkish-speaking people.

RESUMEN

Background/Aim: Cognitive, psychological, and behavioral problems that occur in individuals with Alzheimer's disease (AD) cause impairments in the daily living functions of patients and affect their quality of life adversely. Non-pharmacological treatments are becoming more and more prominent due to the lack of side effects and the effective results from various studies. This study aims to examine the effectiveness of holistic therapy (reminiscence, music, and reality orientation therapy) on depression levels, quality of life, and cognitive status in individuals with AD. Methods: Ten people with AD were included in the holistic therapy program for six weeks and ten were included in the control group. All individuals took the mini-mental state examination (MMSE), geriatric depression scale short form (GDS-SF), Nottingham health profile (NHP), and World Health Organization quality of life instrument, elderly module, Turkish version (WHOQOL-OLD) before and after the therapy. Results: The initial and final assessment results were compared in the therapy group; there was a significant increase in the MMSE scores and a significant decrease in the GDS-SF scores (P < .05). According to the NHP and WHOQOL-OLD scales, there was a significant increase in the quality of life of the patients in the therapy group (P < .05). Conclusion: In this study, a significant improvement was observed in the therapy group in the following aspects: cognition, depression level, and quality of life-especially in sleep, social isolation, emotional reaction, energy, autonomy, intimacy, fear of death, and emotional ability areas. Therefore, non-pharmacological treatment, such as holistic therapy, can be used together with pharmacological treatment in people with AD.

RESUMEN

The purpose of this research was to investigate speech-language pathologists' (SLPs) perspectives, attitudes, and experiences of using telepractice for preschoolers in Turkey. A mixed-method online survey was used with SLPs who implemented telepractice with preschool children. Frequency distribution and theme analysis were used to examine the data. Therapy was the most offered online service (98%). Further, 67% of SLPs worked with speech sound disorders. More than half of SLPs felt confident offering telepractice to preschoolers. Most respondents thought that telepractice was an appropriate and easily accessible approach for preschool children, with the applicability of telepractice connected to a child's type of problem. The SLPs were motivated by the numerous advantages of telepractice. However, their opinions were divided when telepractice was compared to in-person treatment. The SLPs in Turkey must be better educated about telepractice, and clinical standards established. The findings point to areas of telepractice that might be improved for preschoolers, especially in Turkey.

RESUMEN

PURPOSE: The purpose of this study was to develop a novel teacher-reported pediatric voice outcome measure and to investigate its psychometric properties. METHOD: In the first stage, a new instrument, the Teacher-Reported Pediatric Voice Handicap Index (TRPVHI), was developed. After item generation, a panel of experts evaluated the items to assess the content validity. Subsequently, the final version of the preliminary instrument was applied to teachers of 306 children (57 dysphonic and 249 vocally healthy) between the ages of 4 and 11 years. Eventually, the construct validity, criterion-related validity, test-retest reliability, and internal consistency of the developed instrument were examined. RESULTS: The items with a content validity ratio less than .8 were modified or removed, and accordingly, the preliminary version of the index was finalized. After the application of the preliminary version, item reduction was made based on the factor analysis. The index is composed of 27 questions and three subscales: Functional, Physical, and Emotional. A significant difference was observed between the dysphonic and vocally healthy children for the TRPVHI scores (p < .001). A positive moderate correlation was determined between the Pediatric Voice Handicap Index and TRPVHI scores. Correlation coefficients between the test and retest scores of the TRPVHI were in the range of .92-.98. Cronbach's alpha values computed to assess the internal consistency were in the range of .94-.98. CONCLUSIONS: The TRPVHI is the only valid and reliable teacher-reported outcome measure of the effects of voice disorders on children. It is anticipated that the deployment of the TRPVHI in conjunction with other subjective tools, both in the initial evaluation and the follow-up of the treatment results, will allow a better understanding of the physical, functional, and emotional effects of voice disorders on children. Furthermore, it can potentially lead further research to enable the use of the TRPVHI for screening purposes.

RESUMEN

In PWA (people with aphasia) difficulties with sentences that refer to the past compared to non-past time reference have been shown for many languages, including Turkish. However, the impact of morphological complexity on past time reference ability in production has not yet been reported for Turkish-speaking PWA. Turkish, where verb forms have complex inflectional paradigms and exhibit overt and non-overt morphology, facilitates the examination of the effects of morphological complexity. The current study has two objectives: 1) to investigate whether the morphological complexity of the verb form affects time reference production of Turkish-speaking PWA and 2) to provide analysis for the error patterns discovered. Seventeen Turkish individuals with Broca's aphasia who were matched in age with a control group of 17 neurologically intact Turkish individuals were tested with a picture sentence completion task. Test conditions were present progressive, simple past, past perfect, past progressive, and future tense. The task required the participants to complete each sentence frame with a verb. Our findings show that Turkish-speaking PWA were more successful in producing verb forms referring to non-past than verb forms referring to the past time reference. The current study supports previous findings that past is more difficult than non-past time reference for Turkish-speaking PWA. In terms of morphological complexity, we find that PWA were more impaired when producing morphologically complex verb forms rather than morphologically simple forms. We argue that these impairments lie in the realization of overt morphology.

RESUMEN

OBJECTIVES: This study aimed to determine the cepstral acoustic parameters that vary depending on age and gender in vocally healthy children, and to establish normative data for cepstral analysis. BACKGROUND: Cepstral measurements are among the strongest predictors of auditory-perceptual evaluation of voice and differentiate between healthy and dysphonic voices. More spesificially, ceptral peak prominence is accepted to be as a strong acoustic predictor of breathiness and overall severity of dysphonia. Cepstral measures determine voice quality reliably not only in sustained vowel samples but also in running speech samples. Determining the parameters related to the acoustic profile of children with normal voices can lead us to a better understanding of the effect of changes in the larynx and vocal fold structure during growth and development. There is a limited number of norm studies examining the cepstral acoustic properties of pediatric voice. Determining norm-specific values and clinical guidelines of cepstral acoustics according to the age and gender in vocally healthy children are utmost important. METHODS: A total of 160 vocally healthy children were divided into the following four age groups: Group-I included children within the age range of 4-7 years, Group-II included 7-11 years, Group-III 11-14 years, and Group-IV included children within the age range of 14-18 years. An equal number of male and female participants were assigned to each group. PENTAX Medical CSL Model 4500 was used for recording all tasks. For acoustic analysis, Multi-Dimensional Voice Program and Analysis of Dysphonia in Speech and Voice were used. RESULTS: Cepstral Peak Prominence (CPP), Cepstral Peak Prominence Standard Deviation (CPP SD), and Low-To-High Spectral Ratio (L/H Ratio) increased with age. It is found that the CPP parameter of all-voiced sentences and nasal-weighted sentences increased with age in boys, while no significant pattern was observed in any sample for girls. For L/H ratio, it can be said that there is a general increase with age in all speech samples, except for the vowel-weighted and voiceless plosive sentence samples, evident especially in the group above the age of 15 years. This study concluded that the CPP SD parameter in the vowel-weighted sentences increased with age in boys. It was also noticed in this study that CPP F0 standard deviation (SD) intervals were narrower in vowel-weighted, easy onset, and voiceless plosive sentence samples than in all-voiced, hard glottal attack and nasal-weighted sentence samples. CONCLUSION: This study established cepstral acoustic normative values for a wide age range of the pediatric population. It is thought that age and gender specific cepstral acoustic findings presented in this study contributed to the related literature. In addition, to our knowledge, this is the first study that provides a normative cepstral acoustic database of the CAPE-V/Turkish sentences in the pediatric population.

RESUMEN

BACKGROUND: Self-assessments for adults who stutter are recommended as a primary evaluation tool for including their views on stuttering. Evaluating adults who stutter with self-assessment scales is important. However, there is no tool in the Turkish literature that provides this measurement. AIMS: To develop the Turkish version of The Wright and Ayre Stuttering Self-Rating Profile (WASSP) in order to analyse its validity and reliability, and investigate its applicability for Turkish-speaking individuals. METHODS & PROCEDURES: The study included 120 adults who stutter (aged 18-54 years). All the participants completed The Wright and Ayre Stuttering Self-Rating Profile-Turkish version (WASSP-TR) and the SF-36 form. The reliability analysis involved the calculation of Cronbach's alphas for test-retest and the Pearson product-moment correlation coefficient for internal consistency. The validity analysis, in turn, involved a confirmatory factor analysis for construct validity and testing correlations with the SF-36 for criterion validity. OUTCOMES & RESULTS: Internal consistency coefficients of the WASSP-TR were reported to be high (> 0.70). The correlations between the WASSP-TR and its subscales showed significant results (0.858-0.966) (p < 0.01). The correlation between the subscales of the WASSP-TR and the SF-36 was reported to be consistent (from -0.492 to 0.747). There was a positive correlation between stuttering severity groups and the WASSP-TR scores (p < 0.01). CONCLUSIONS & IMPLICATIONS: The WASSP-TR is a valid and reliable scale for Turkish-speaking adults who stutter. What this paper adds What is already known on the subject Self-assessment tools are recommended as a primary use when assessing adults who stutter. The WASSP is one of these measurement tools. However, the adaptation, validity and reliability study of the WASSP to Turkish has not been investigated. What this paper adds to existing knowledge This study shows that the Turkish version of the WASSP scale is valid and reliable and can be used with adults who stutter. Furthermore, the present adaptation study has been developed in order to evaluate social-emotional aspects of stuttering. What are the potential or actual clinical implications of this work? A tool that includes evaluating the behaviour, cognition, affect and participation areas as well as the stuttering behaviours of adults who stutter was adapted. This tool is expected to be useful for comprehensive evaluation of adults who stutter in clinics, in research and for pre/post-therapy.

RESUMEN

OBJECTIVES: Normal voice can be differentiated from dysphonic voices by comparing their characteristics using an established normative database. Pediatric normative data using the Phonatory Aerodynamic System (PAS) have been established in a preliminary study for English-speaking children. However, aerodynamic measures, including physical characteristics varying by geographic region, race, and culture, must be investigated between children with different native languages. Aerodynamic analysis of connected speech requires the collection of language-specific samples and the establishment of language-specific norms. Thus, the main purpose of the present study was to establish pediatric normative data using the PAS for a large pediatric population of healthy Turkish-speaking children of 4-17.11 years of age. Another research aim was to determine age-dependent and/or gender-dependent aerodynamic parameters for this pediatric population. METHODS: In total, 120 children were divided into four age groups: Group I, 4-5.11 years; Group II, 6-9.11 years; Group III, 10-13.11 years; and Group IV, 14-17.11 years. An equal number of male and female participants were assigned to each group. The PENTAX Medical PAS Model 6600 was used. Descriptive statistics for 56 parameters across six protocols were expressed as mean, standard deviation, and range values. Each protocol was analyzed for age, gender, and age-gender interaction. RESULTS: Age was the most predominant factor, affecting 37 of the 56 aerodynamic parameters investigated. Gender and age-gender factors were observed at an equal frequency, each affecting 16 parameters. Pitch-related parameters were the most altered parameters in each protocol. Age-gender interaction was observed in parameters related to the expiratory airflow. CONCLUSIONS: This study established the normative values of phonatoary aerodynamics for a large pediatric population with a wide age range and developed a normative database for healthy Turkish-speaking children. This is the first study to investigate running speech protocol in aerodynamic assessment.

RESUMEN

OBJECTIVE: The main purpose of this study is to investigate the effectiveness of a 12-week holistic vocal training program designed for theatre students. METHODS: The participants included 10 female and 8 male students, who were third- and fourth-year students of a state conservatory theatre department. Participants randomly selected from among those who were between the ages of 18-30 years, had no history of voice disorders, and had no systemic and neurological disorders. The study group (n = 9) was involved in the vocal training program. The control group (n = 9) has not received any training. During the program, 12 sessions of lectures and voice exercises were given to all participants of the study group for a period of 12 weeks. The sessions were planned to last for a duration of 30-45 minutes. Participants' knowledge of vocal health was assessed using a questionnaire that was developed in the present study and a multidimensional voice assessment protocol including acoustic analyses and audio-perceptual evaluation has been applied. RESULTS: Within-group comparisons indicated a significant increase in the study group participants' knowledge of vocal hygiene after training (P = 0.011). Similarly, the study group outperformed the control group in the vocal mechanism knowledge (P = 0.027). Multidimensional Voice Profile findings revealed that vocal qualities of the control group deteriorated, whereas no alterations were found in the study group. Audio-perceptual analysis conducted through the Consensus Auditory-Perceptual Evaluation of Voice did not introduce significant changes in the control group in overall severity and roughness parameters, these values were found significantly improved for the study group. CONCLUSION: It can be concluded that the Holistic Vocal Training Program designed in the present study is effective for preserving theatre students' vocal health and voice quality. It is important for future studies to search the long-term effects.

RESUMEN

The aim of the study was to present the hearing and speech-language findings of preschool children. The children in this study were aged 3-5 years. Sixtyseven of 239 children (28.0%) had been referred to a physician because of possible middle ear problems, and 25 of the 67 children had slight and mild conduction type hearing loss with air-bone gaps. One of 239 children had profound sensorineural hearing loss. Speech-language problems were found in 70 of 239 children (29.3%). Necessary attention should be paid to the evaluation of hearing and speech-language skills in preschool-aged children to avoid delayed detection and to give these children the opportunity for timely intervention for hearing and speech-language problems.
