Validity and Reliability of the Turkish Version of the Emotional Communication in Hearing Questionnaire.

PURPOSE: The Emotional Communication in Hearing Questionnaire (EMO-CHeQ) is designed to evaluate awareness of vocal emotion information and perception of emotion. This study sought to translate the EMO-CHeQ into Turkish in accordance with international standards and to ascertain its validity and reliability statistically by administering it to native Turkish-speaking subjects. METHOD: This empirical study involved collecting data from participants using a scale. A total of 460 individuals, comprising 158 women and 302 men (Mage = 33.43 ± 13.14 years), participated. The data encompassed 295 subjects with normal hearing, 101 hearing aid users, and 64 cochlear implant users. Exploratory factor analysis, followed by confirmatory factor analysis, was employed to ensure construct validity. Internal consistency was assessed with Cronbach's alpha reliability analysis, and content validity was applied to examine how effectively the Turkish version of the scale fulfilled its intended purpose. RESULTS: The total Cronbach's alpha internal consistency coefficient of the scale was .949, and the explained variance was 74.385%. The Turkish version of the EMO-CHeQ demonstrated high construct validity, internal consistency, and explanatory efficacy. The scale revealed significant differences (p < .05) in emotional communication among the normal-hearing group, hearing aid users, and cochlear implant users. CONCLUSIONS: The Turkish adaptation of the EMO-CHeQ is a credible and robust tool for evaluating how individuals perceive emotion in speech. Emotion perception was found to be suboptimal among hearing aid users compared to cochlear implant users, although it was most proficient in those with normal hearing.

Clinically recorded cortical auditory evoked potentials from paediatric cochlear implant users fitted with electrically elicited stapedius reflex thresholds.

OBJECTIVES: This study aimed to objectively evaluate access to soft sounds (55 dB SPL) in paediatric CI users, all wearing MED-EL (Innsbruck, Austria) devices who were fitted with the objective electrically elicited stapedius reflex threshold (eSRT) fitting method, to track their cortical auditory evoked potential (CAEP) presence and latency, and to compare their CAEPs to those of normal-hearing peers. METHODS: Forty-five unilaterally implanted, pre-lingually deafened MED-EL CI users, aged 12-48 months, underwent CAEP testing in the clinic at regular monthly intervals post switch-on. CAEPs were recorded in response to short speech tokens /m/, /g/ and /t/ presented in the free field at 55 dB SPL. Twenty children with normal hearing (NH), similarly aged, underwent CAEP testing once. RESULTS: The proportion of present CAEPs increased and CAEP P1 latencies reduced significantly with post-implantation duration. CAEPs were scored based on their presence and age-appropriate P1 latency. These CAEP scores increased significantly with post-implantation duration. CAEP scores were significantly worse for the /m/ speech token compared to the other two tokens. Compared to the NH group, CAEP scores were significantly smaller for all post-implantation test intervals. CONCLUSIONS: This study provides clinicians with a first step towards typical ranges of CAEP presence, latency, and derived CAEP score over the first months of MED-EL CI use. CAEPs within these typical ranges could validate intervention whereas less than optimum CAEPs could prompt clinicians to seek solutions in a timely manner. CAEPs could clinically validate whether a CI provides adequate access to soft sounds. This approach could form an alternative to behavioural soft sound access verification.

Comparing eSRT and eCAP measurements in pediatric MED-EL cochlear implant users.

INTRODUCTION: Electrically evoked compound action potentials (eCAP) and electrically evoked stapedius reflexes are the most frequently used objective measurements for programming a cochlear implant (CI) audio processor. Objective methods are particularly beneficial for children and CI users that encounter difficulties in providing feedback. In this study, we compared the threshold and the slope of the eCAP amplitude growth function with the electrically evoked stapedius reflex threshold (eSRT) in pediatric CI users. Furthermore, the duration times required to perform eCAP and eSRT recordings were compared. METHODS: During a regular fitting session, 52 pediatric CI users with recordable eSRTs having MED-EL devices (MED-EL GmbH, Innsbruck, Austria) were programmed using the eSRT fitting method. The eCAP thresholds and the slopes of the amplitude growth function were measured across one apical, one medial, and one basal electrode contact. RESULTS: There was a weak to medium correlation between eCAP thresholds and eSRTs. The eCAP threshold profile did not correlate with the eSRT profile. Typically ECAP thresholds were at a lower stimulation charge than eSRTs with only 4/152 being higher. An eCAP threshold was found on 152/156 electrode contacts with eSRTs. On average, the eCAP measurements took 4.2 times longer to record per electrode than eSRT measurements (median durations 35 s vs. 120 s). CONCLUSION: eSRTs were significantly higher than eCAP thresholds and eSRT and eCAP profiles were generally different from each other reducing the clinical relevance of eCAP testing for setting MCLs across the array. Additionally, the eSRT measurements were faster to record than the eCAP threshold and slope determination measurements.
