Fall Risk In Community-Dwelling Adults: A Comparison Of English And Spanish-Speaking Individuals, Jesus D. Gomez Aug 2026

Fall Risk In Community-Dwelling Adults: A Comparison Of English And Spanish-Speaking Individuals, Jesus D. Gomez

Dissertations, 2020-current

Falls are a leading cause of injury-related mortality among middle-aged and older adults. Although vestibular dysfunction, hearing loss, behavioral factors, and social determinants of health have been associated with increased fall risk, few studies have examined these relationships. Furthermore, limited research in audiology and vestibular science has investigated fall-risk vulnerability among Spanish-speaking individuals.

This study aimed to: (1) estimate the prevalence of fall risk among community-dwelling adults and compare prevalence between English-speaking and Spanish-speaking participants; (2) assess the prevalence of previously undiagnosed benign paroxysmal positional vertigo (BPPV) and compare prevalence between language groups; and (3) develop predictive models of fall …

Discourse Production And Its Relationship To Cognition In Mild Aphasia, Marcy D. Edwards Jun 2026

Discourse Production And Its Relationship To Cognition In Mild Aphasia, Marcy D. Edwards

USF Tampa Graduate Theses and Dissertations

Objective:Standardized assessments such as the Western Aphasia Battery-Revised do not reliably detect subtle language impairments in mild aphasia (Dalton & Richardson, 2015). Discourse tasks may provide a more sensitive measure of impairment. Although discourse tasks differ in cognitive demands (Kim & Kintz, 2024), variation in discourse performance across tasks and the influence of cognition remains unclear. Therefore, this study examined (1) whether discourse performance differs across different discourse elicitation tasks, and (2) the extent to which cognition influences discourse performance in individuals with mild aphasia.

Participants & Methods: Fifteen participants with mild aphasia participated (mean age = 62.7 years). Discourse …

Determinants Of Corporal Punishment And Severe Physical Punishment In Egypt: A Mixed-Methods Analysis For Child Protection Policy, Marwa Moustafa Nassef

Theses and Dissertations

Corporal punishment (CP) and severe physical punishment (SPP) remain a major public health, child rights, and child protection policy concern. In Egypt, despite legislative reforms, survey-weighted analysis of the 2021 Egypt Family Health Survey (EFHS) 2021 (CAPMAS, 2022) reveals prevalence rates of 60.5% for CP and 27.4% for SPP among children aged 1–14 (author’s calculations using EFHS-2021, n=7623), yet evidence distinguishing the determinants of routine corporal punishment from escalation to severe physical punishment remains limited in low- and middle-income contexts. Guided by Bronfenbrenner’s ecological framework, this mixed-methods study identifies key drivers of CP and its escalation to SPP among Egyptian …

Implicit Attitudes Toward Hearing Aid Visibility: Conspicuous Versus Inconspicuous Hearing Aid Colors, Orly R. Ames

Dissertations, Theses, and Capstone Projects

Hearing aid stigma remains a significant barrier to treatment uptake, with device visibility frequently identified as a contributing factor. Although prior research has examined visibility in relation to hearing aid size and style, the role of color as a distinct aesthetic dimension has not been systematically investigated. The present study assessed whether hearing aid color affects implicit and explicit attitudes toward hearing aids and whether such evaluations differ across contexts. Twenty-six adults who were not current hearing aid users participated in an online quantitative multi-method study consisting of an Implicit Association Test (IAT) and self-report questionnaires. The IAT measured implicit …


Enhancing Ecological Validity In Speech-In-Noise Testing: Integrating Virtual Reality For A Multisensory Audiological Experience, Paulina Lee Jun 2026

Enhancing Ecological Validity In Speech-In-Noise Testing: Integrating Virtual Reality For A Multisensory Audiological Experience, Paulina Lee

Dissertations, Theses, and Capstone Projects

Despite the remarkable advances in hearing healthcare technology, the speech recognition tests used in routine clinical audiological assessment have remained essentially the same for decades.  Monosyllabic word recognition tests in quiet, such as the Northwestern University Auditory Test No. 6 (NU-6; Tillman & Carhart, 1966), have served as the audiology field’s default measure of speech understanding.  Modern speech-in-noise (SIN) tests, such as the QuickSIN (Killion et al., 2004), have emerged, yet they remain auditory-only, leaving an unignorable gap between what clinical tests measure and how patients communicate in daily life.  The present study examined whether pairing a standard SIN test …


A Comparison Of Manufacturers’ Claims Of Attenuation Rates In Non-Custom Earplugs, Skyler M. Shipley Jun 2026

A Comparison Of Manufacturers’ Claims Of Attenuation Rates In Non-Custom Earplugs, Skyler M. Shipley

Dissertations, Theses, and Capstone Projects

Recreational and social environments frequently expose individuals to high intensity noise environments; however, the use of hearing protection devices (HPDs) remains limited. This study evaluated whether non-custom, over-the-counter musicians’ earplugs provide attenuation consistent with manufacturers’ claims and whether cost is associated with performance. Six commercially available earplug models were tested using both human participants and a KEMAR manikin system. Attenuation was measured across frequencies from 250–8000 Hz (octave and inter-octave frequencies) and were tested using different ear tip sizes. Results indicated that several earplugs achieved attenuation levels comparable to or exceeding their advertised noise reduction ratings (NRR), though consistency varied …

Exploring Direct Support Professionals' (Dsps) Attitudes Regarding Trauma Informed Care And Its Impact On Turnover Intention, Lorraine D'Sylva-Lee

Seton Hall University Dissertations and Theses (ETDs)

The relationship between Direct Support Professionals’ (DSPs’) attitudes toward trauma-informed care (TIC) and their turnover intention has remained empirically untested, despite DSPs’ exposure to primary and secondary trauma. An estimated 8.38 million Americans with intellectual and developmental disabilities (IDD) depend on this workforce, yet 2024 turnover rates reach 53.7%. This convergent mixed methods study examined TIC attitudes, turnover intention, and their relationship among 109 DSPs in IDD provider agencies in New Jersey. Grounded in the Theory of Planned Behavior (TPB), the cross-sectional design used the ARTIC-10, TIS-6, and two open-ended items. DSPs with more favorable TIC attitudes were significantly less …


Family Quality Of Life And Infant Language Development: A Pilot Study Of Infants Without A History Of Chronic Otitis Media, Aubreigh Cartwright May 2026

Family Quality Of Life And Infant Language Development: A Pilot Study Of Infants Without A History Of Chronic Otitis Media, Aubreigh Cartwright

Dissertations, 2020-current

Chronic otitis media (COM) is a condition associated with hearing fluctuations, recurrent medical interventions, and speech-language concerns. While the audiological impacts for children are well documented, there is less research pertaining to parents’ and caregivers’ experiences. The goal of the overall line of inquiry was to examine the impact of chronic otitis media on parent and caregiver quality of life. Parents and caregivers of ten typically developing infants from six to twelve months of age without COM were administered parent-proxy instruments to determine quality of life, as well as expressive and receptive lexicon. The parents were administered a family intake …


A Measure Of Spatial Orientation In Healthy Adults, Lauren Maloney May 2026

A Measure Of Spatial Orientation In Healthy Adults, Lauren Maloney

Dissertations, 2020-current

Spatial orientation is essential for effective navigation and movement, relying on the integration of sensory inputs from systems such as proprioception, vision, audition, and the vestibular system. The vestibular system, responsible for detecting rotational and linear movements, plays a crucial role in maintaining balance and spatial awareness. However, its specific influence on spatial orientation remains underexplored. This study investigates how vestibular input influences spatial orientation accuracy by examining participants' ability to estimate angular displacement during rotational stimuli. Twenty participants underwent testing using a rotational chair, with stimuli at varying rotational amplitudes (5-400 degrees). Along with their perceived angular displacement (i.e. …


The Effect Of Head Coverings On Directional Microphone Performance, Mariam Mohamed May 2026

The Effect Of Head Coverings On Directional Microphone Performance, Mariam Mohamed

Dissertations, 2020-current

Background: Directional microphones in hearing aids are a well-established strategy for enhancing speech intelligibility in background noise. While previous studies have examined the effects of hair, spectacles, and earmold venting, no systematic research has addressed whether head coverings, commonly worn for cultural, religious, or personal reasons, affect directional performance.

Objective: This study aimed to determine whether a thin cotton head covering alters the directivity index (DI) of premium receiver-in-canal hearing aids from four leading manufacturers, using laboratory-controlled conditions. 

Methods: A Knowles Electronics Manikin for Acoustic Research (KEMAR) was positioned within a sound-treated room to measure DI for both omnidirectional and …

How Audiologists Are Using Adapted Cognitive Behavioral Therapy For Tinnitus Management: A Preliminary Study, Katherine M. Mueller

Dissertations, 2020-current

Audiologists interact with patients reporting bothersome tinnitus frequently, however there is no standardized protocol to follow when treating/counseling these patients. Cognitive Behavioral Therapy (CBT) is highly researched and has been proven to alleviate bothersome tinnitus symptoms, yet audiologists are not clinically trained in this tinnitus management. Specific forms of CBT that were analyzed in this study include Attention Shifting, Neurophysiological Education, and Progressive Muscle Relaxations. This study surveyed current audiologists to determine how they are using adapted CBT techniques (aCBTt) for tinnitus management. This questionnaire aimed to investigate a) the effect of audiologists’ practice duration on their frequency to recommend …


Stigma Predicts Participation And Autonomy In Chronic Vestibulopathy: An Explanatory Mixed Methods Study, Brandy L. Hollins May 2026

Stigma Predicts Participation And Autonomy In Chronic Vestibulopathy: An Explanatory Mixed Methods Study, Brandy L. Hollins

Dissertations, 2020-current

Many vestibular disorders are “invisible”, not widely recognized, and challenging for patients to describe. However, its impact is visible and leads to significant challenges. Research has shown that stigma associated with other chronic health conditions can detrimentally affect patient outcomes, suggesting a greater need in this area. The World Health Organization’s (WHO) International Classification of Functioning, Disability, and Health (ICF) elucidates the role of physical, social, and cultural factors in the manifestation of health conditions within a universal framework. A critical aspect of the ICF’s contextual factors for individuals with vestibular loss is societal perception. Few studies have reported stigmatization …


Novel Paradigm For Assessing Vestibular Perception In Children, Nicole Kirk May 2026

Novel Paradigm For Assessing Vestibular Perception In Children, Nicole Kirk

Dissertations, 2020-current

While objective vestibular reflexive testing has been heavily researched, there are few studies analyzing subjective vestibular perception and to date no progress has been reported on motion perception in children. It is unknown if children perceive motion like adults creating a need for research comparing these age groups for thorough clinical profiles. This study adapted an adult psychophysics protocol for school-aged children and collected data on ten typically developing children and ten healthy adults. Participants rotated at various peak velocities and frequencies in a rotary chair and were asked to report their spatial orientation (i.e., how far around they rotated) …


How Screen Time Affects Language Development In Children Ages Three To Five Years, Alyssa R. Sherman May 2026

How Screen Time Affects Language Development In Children Ages Three To Five Years, Alyssa R. Sherman

Honors Thesis

Screen time has become an increasingly prominent part of early childhood, particularly following shifts in daily routines after the COVID-19 pandemic. This literature review examines how screen time affects language development in children ages three to five, a critical developmental period for expressive and receptive language skills. The review synthesizes current research on the use of passive and interactive screens and their associations with language acquisition, cognitive development, social communication, and physical health outcomes. Across studies, a consistent pattern emerges: excessive screen time is strongly associated with delayed language milestones, reduced social communication skills, poorer sleep quality, and increased physical …

Investigating Speech-Language Pathologists’ Perceptions On Bilingual/Multilingual Aac Intervention And Quality Of Care, Lillian D. Griffith

Communication Disorders and Occupational Therapy Undergraduate Honors Theses

This study examined U.S.-based speech-language pathologists' (SLPs) perceptions of bilingual/multilingual AAC service provision and the barriers SLPs encounter to determine if SLP beliefs align with practices. An anonymous survey was distributed to 307 ASHA-certified SLPs, resulting in 21 completed responses. The survey consisted of questions that gathered information on participant demographics, caseload, perceptions/beliefs, and practices, with optional open-ended questions for additional context. SLPs in the participant sample strongly believed that AAC intervention should occur in all the languages spoken by the client. Despite this belief, they struggled to implement it due to barriers. Key barriers identified included SLP language limitations, …


Patterns Of Acquisition For /ɹ/ Across Phonetic Contexts, Hailey Nielson May 2026

Patterns Of Acquisition For /ɹ/ Across Phonetic Contexts, Hailey Nielson

All Graduate Reports and Creative Projects, Fall 2023 to Present

Purpose: 

This study examined longitudinal changes in /ɹ/ production (i.e., the “r” sound) among 14 children aged five to seven at risk for persistent speech sound disorders (SSDs). Children at risk for SSDs show slower or atypical development of /ɹ/, yet little is known about which early patterns predict persistent difficulty, making it difficult for clinicians to prioritize caseloads and provide timely intervention. Using perceptual accuracy ratings across varied /ɹ/ contexts, we modeled growth in /ɹ/ accuracy across different word contexts and evaluated the extent to which early accuracy and changes in /ɹ/production predicted mastery at age seven.

Methods: 

Longitudinal …


Challenging Myths In Speech-Language Pathology: A Scientific Review Of Augmentative And Alternative Communication (Aac) Use, Bilingualism, And Late Talking, Mariah Morris May 2026

Challenging Myths In Speech-Language Pathology: A Scientific Review Of Augmentative And Alternative Communication (Aac) Use, Bilingualism, And Late Talking, Mariah Morris

Undergraduate Honors Capstone Projects

Persistent myths within the field of speech-language pathology continue to influence clinical decision-making and contribute to biases experienced by both providers and clients. This scientific review examines common misconceptions surrounding late talking, bilingualism, and augmentative and alternative communication (AAC) by evaluating current evidence-based research. Specifically, this review addresses three central questions: Do children outgrow late talking? Does bilingualism cause language delay in children? Does AAC hinder speech development? 

An analysis of multiple peer-reviewed studies revealed little statistical support for the belief that bilingualism or AAC use causes language delays. Instead, research indicates that factors such as limited access to language-rich …
