The Validity and Reliability of the Turkish Version of Preschool Hearing Environments and Reflection on Quality of Life Questionnaire.

PURPOSE: The purpose of this study was to assess preschool children's hearing-related quality of life and to introduce the scale, originally titled "Preschool Hearing Environments and Reflections on Quality of Life Questionnaire" (Preschool HEAR-QL), to the literature through Turkish adaption, validity, and reliability analyses. METHOD: Our study included 210 children aged 2-6 years: 110 with hearing loss (56 cochlear implant users and 54 hearing aid users) and 100 with normal hearing. Demographic data were collected and then the Preschool HEAR-QL, which was translated into Turkish, was administered twice at 15-day intervals. Confirmatory factor analysis was used to determine whether the factor structure found in the original scale development study was confirmed in our sample (construct validity). Cronbach's alpha, intraclass correlation scores, and the test-retest method were used to assess the scale's reliability as the findings were analyzed using paired samples t tests. RESULTS: The children with hearing loss had lower scores than their normal-hearing peers, and the difference was significant in the subdomains of behavior and attention, hearing environments, and communication. The subscale of the Preschool Period Listening Environments and their Reflections on Quality of Life Scale consists of 23 items, and Cronbach's alpha value was found as 0.922 in the first application and 0.926 in the second application (high reliability). In the model established for validity analysis, χ2/df = 2.156, root-mean-square error of approximation = 0.074, standard root-mean-square residual = 0.078, goodness-of-fit index = 0.830, adjusted goodness-of-fit index = 0.789, comparative fit index = 0.895, and Tucker-Lewis index = 0.881 (good model fit). In terms of test-retest reliability, the correlation between the two measurements was 0.837, and there was no statistical difference between the test-retest scores (p = .15). CONCLUSION: The Turkish version of the Preschool HEAR-QL scale was proven to be a valid and reliable scale for assessing the hearing-related quality of life of children aged 2-6 years.

Evaluation of Voice in Inflammatory Bowel Diseases.

INTRODUCTION: Inflammatory bowel diseases, which are among the most common chronic gastrointestinal diseases, can also affect the voice for different reasons.The aim of this study is to investigate acoustic, perceptual and subjective voice evaluation parameters in inflammatory bowel diseases (IBD). METHODS: This prospective case-control study included a total of 80 participants: 28 patients with ulcerative colitis (UC), 22 patients with Crohn's Disease (CD), and 30 healthy controls. Following the endoscopic examination, the fundamental frequency (F0), shimmer (dB), jitter (%), and harmonic/noise ratio (HNR) were measured. GRBAS (grade, roughness, breathiness, asthenia, strain) scale was used for perceptual evaluation, Voice Handicap Index-10 (VHI-10) Turkish version was used for subjective assessment. RESULTS: The F0 value was within normal limits in both disease groups in male and female participants and in the control group. Jitter and shimmer values were statistically higher in the UC and CD groups than the control group. HNR did not differ between CD and control, however it was statistically lower in the UC group when compared to both the control and CD group. The total GRBAS score did not differ between the UC and CD groups, however it was greater in IBD patients compared to the control group. However these differences were within normative parameters. Although total VHI-10 score did not differ between UC and CD groups, both had higher voice handicap than the control group. CONCLUSION: IBD might have an effect on the voice and voice quality. This disease group was discovered to have perceptual and subjective voice problems additionally.

Organic and functional dysphonias: comparison of Self-Assessment protocols by confirmatory factor analysis.

OBJECTIVE: This study aims to see if the effects of the sub-domains of the Voice Handicap Index-10 (VHI-10) and Voice Related Quality of Life (VRQoL) differ in organic (OD) and functional dysphonia (FD). METHOD: A total of 162 patients completed the validated Turkish versions of the Voice Handicap Index-10 (VHI-10) and Voice-Related Quality of Life (VRQoL). Physical (pVHI-10), emotional (eVHI-10) and functional (fVHI-10) sub-domains of VHI-10 and physical-functional (PF-VRQoL), socio-emotional (SE-VRQoL) dimensions of VRQoL were assessed. Confirmatory factor analysis (CFA) was used to compare the sub-domains of these questionnaires between diagnostic categories. RESULTS: The total and sub-domain scores of both VHI-10 and VRQoL were not statistically different between the two etiologic categories of dysphonia (MANOVA, p > .05). The total VHI-10 and total VRQoL scores were significantly and moderately correlated in both the OD and FD groups. During CFA, 4 models were constructed for the OD and FD groups for VHI-10 and VRQoL factors. There was no significant difference between OD and FD groups in terms of path coefficients of sub-domains (z test, p > .05). CONCLUSION: In terms of VHI-10 and VRQoL, the sub-domains of each questionnaire are equally important in both organic and functional dysphonia. Functional disorders do not depend only on "emotional" factors, and neither do organic problems. Factor analysis should be included when performing a study on patient-reported outcome measures.

Effects of Subthalamic Nucleus Deep Brain Stimulation Surgery on Voice and Formant Frequencies of Vowels in Turkish.

AIM: To investigate the effects of deep brain stimulation (DBS) of the subthalamic nucleus (STN) on acoustic characteristics of voice production in Turkish patients with Parkinson's disease (PD). MATERIAL AND METHODS: This study recruited 20 patients diagnosed with PD. Voice samples were recorded under the "stimulation on" and "stimulation off" conditions of STN-DBS. Acoustic recordings of the patients were made during the production of vowels /a/, /o/, and /i/ and repetition of the syllables /pa/-/ta/-/ka/. Acoustic analyses were performed using Praat. RESULTS: A significant difference in the parameters was observed among groups for vowels. A positive significant difference was observed between preoperative med-on and postoperative med-on/stim-on groups for /a/ and the postoperative med-on/ stim-on and postoperative med-on/stim-off groups for /o/ and /i/ for frequency perturbation (jitter) and noise-to-harmonics ratio. No significant difference was noted between the preoperative med-on and postoperative med-on/stim-off groups for any vowels. CONCLUSION: STN-DBS surgery has an acute positive effect on voice. Studies on formant frequency analysis in STN-DBS may be expanded with both articulation and intelligibility tests to enable us to combine patient abilities in various perspectives and to obtain precise results.

Profiling morpho-syntactical development of cochlear implanted children with TR-LARSP.

This research aims to describe the grammatical development of Turkish-speaking children with cochlear implants (CI) using the Turkish adaptation of the Language Assessment and Remediation Profile (LARSP). The study was conducted on a total of 15 children with CIs aged 43-87 months with 22-45 months of hearing age. A total of 750 utterances were elicited from the CI group's recorded speech samples and analysed using the methodology of Turkish-Language Assessment and Remediation Profile (TR-LARSP). A cross-sectional descriptive model is used in the study. The results show that there is a significant difference in the acquisition of grammatical structures in children with CIs as compared to typically developing (TD) age-matched children in Turkish. In conclusion, this study suggests that after the implantation of these children, the speech therapist should consider the acquisition time of morpho-syntactical structures before making a language-based therapy plan.
