  • The Functional Hearing Inventory
    THE FUNCTIONAL HEARING INVENTORY: CRITERION-RELATED VALIDITY AND INTERRATER RELIABILITY by PAMELA M. BROADSTON, B.S., M.A. A DISSERTATION IN SPECIAL EDUCATION Submitted to the Graduate Faculty of Texas Tech University in Partial Fulfillment of the Requirements for the Degree of DOCTOR OF EDUCATION Approved December, 2003 Copyright 2003, Pamela M. Broadston ACKNOWLEDGEMENTS First and foremost, I thank my Lord, Jesus Christ for opening the door that provided the opportunity for me to obtain this degree. Without His almighty love and endless grace, I would never have achieved this milestone. This milestone could also never have been achieved without the love and support of my family. I cannot proceed without first acknowledging them: to my parents who provided constant love and support throughout this entire endeavor; to my brother Bob, without his financial support I would probably still be working on my master's degrees one class at a time; to my sister, who allowed me to vent and provided sound advice during trying times; to my baby brother, Jeff, thanks for believing in me. I most gratefully thank my dissertation committee for their wisdom, support, and constructive criticism. Their dedication and skilled instruction were vital to the completion of this project. They include: Dr. Carol Layton who provided me with her expertise and guidance in diagnostics and assessment, Dr. Nora Griffm-Shirley who got me hooked on O&M, and Dr. Robert Kennedy who patiently explained and re-explained statistics, time and time again. Last but not least, I want to thank my chair. Dr. Roseanna Davidson, for providing the resources and opportunities that enhanced my doctoral studies and for her expertise and guidance into the field of deafblindness.

  • Dba - Deafblind Australia
    DBA - DEAFBLIND AUSTRALIA Deafblind Australia DBA is a peak national organisation for the deafblind community in Australia. DBA welcomes the opportunity to comment on the inquiry into Hearing Health and Wellbeing to enable Government to engage with deafblind people needs and their supports to ensure they are provided with the care necessary to support their health and wellbeing. ABOUT DEAFBLIND AUSTRALIA (DBA) DBA was established in 1993 at the National Deafblind Conference in Melbourne, Victoria. This council was established to provide: security; sense of belonging; freedom of speech; and represent the Australian deafblind community and their supporting networks. At present, ADBC represents an estimated 300,000 deafblind people including those with multi disabilities, their families and organisations working the deafblind field. SUBMISSION INTO HEARING HEALTH AND WELLBING AFFECTING DEAFBLIND PEOPLE Throughout this submission, the terms deafblind, combined vision and hearing impairment and dual sensory impairment will be used interchangeably as all three are used to describe people with deafblindness. Deafblindness is described by Deafblind Australia as: “a unique and isolating sensory disability resulting from the combination of both a hearing and vision loss or impairment which significantly affects communication, socialisation mobility and daily living. People with deafblindness form a very diverse group due to the varying degrees of their vision and hearing impairments plus possible additional disabilities. This leads to a wide range of communication methods including speech, oral/aural communication, various forms of sign language including tactile, Deafblind fingerspelling, alternative and augmentative communication and print/ braille” Please see below responses to the terms of reference of the inquiry. 1.

  • Deaf-Blindness; Rubella, CHARGE Syndrome, Usher’S Syndrome, Genetic Disorders, Accident and / Or Illness Are Some of the More Common Ones
    Deafblindness Deafblindness is a combination of vision and hearing loss. Deafblindness encompasses a spectrum from mildly hard of hearing plus mildly visually impaired to totally deaf and blind. It is rare that an individual with deafblindness would be completely blind and completely deaf. Individuals who have a combined vision and hearing loss have unique communication, learning, and mobility challenges due to their dual sensory loss. Deafblindness is a unique and diverse condition due to the wide range of sensory capabilities, possible presence of additional disabilities, and the age of onset for the vision and hearing loss. A child with deafblindness would include the infant who has a diagnosis of Retinopathy of Prematurity (a retinal condition that is associated with premature birth) and has an acquired hearing loss due to meningitis at age two. Another person with deafblindness may have been born with a profound hearing loss and developed a later vision loss due to a genetic condition called retinitis pigmentosa. There are many causes of deaf-blindness; Rubella, CHARGE Syndrome, Usher’s Syndrome, genetic disorders, accident and / or illness are some of the more common ones. Deafblindness occurs in three of 100,000 births. In Colorado, just over 140 children and youth (ages birth through 21 years) have been identified as having both a vision and hearing loss. These individuals are eligible for free technical assistance through the Colorado Services for Children and Youth with Combined Vision and Hearing Loss Project, located at the Colorado Department of Education. This project provides technical assistance which supports Colorado children and youth, birth to 21 years, who have BOTH a vision and hearing impairment.

  • Visual Impairment Age-Related Macular
    VISUAL IMPAIRMENT AGE-RELATED MACULAR DEGENERATION Macular degeneration is a medical condition predominantly found in young children in which the center of the inner lining of the eye, known as the macula area of the retina, suffers thickening, atrophy, and in some cases, watering. This can result in loss of side vision, which entails inability to see coarse details, to read, or to recognize faces. According to the American Academy of Ophthalmology, it is the leading cause of central vision loss (blindness) in the United States today for those under the age of twenty years. Although some macular dystrophies that affect younger individuals are sometimes referred to as macular degeneration, the term generally refers to age-related macular degeneration (AMD or ARMD). Age-related macular degeneration begins with characteristic yellow deposits in the macula (central area of the retina which provides detailed central vision, called fovea) called drusen between the retinal pigment epithelium and the underlying choroid. Most people with these early changes (referred to as age-related maculopathy) have good vision. People with drusen can go on to develop advanced AMD. The risk is considerably higher when the drusen are large and numerous and associated with disturbance in the pigmented cell layer under the macula. Recent research suggests that large and soft drusen are related to elevated cholesterol deposits and may respond to cholesterol lowering agents or the Rheo Procedure. Advanced AMD, which is responsible for profound vision loss, has two forms: dry and wet. Central geographic atrophy, the dry form of advanced AMD, results from atrophy to the retinal pigment epithelial layer below the retina, which causes vision loss through loss of photoreceptors (rods and cones) in the central part of the eye.

  • Children Who Are Deaf Or Hard of Hearing with Additional Disabilities
    Children Who Are Deaf or Hard of Hearing with Additional Disabilities Renée Punch PhD Key facts An estimated 30% to 40% of children who are deaf or hard of hearing have an additional disability Approximately 2% of children who are deaf or hard of hearing have an autism spectrum disorder Learning disabilities may be under-diagnosed in children with hearing loss On average, children with additional disabilities have poorer outcomes than those with hearing loss alone Prevalence of additional disabilities The rate of the coexistence of additional disabilities or medical conditions with hearing loss (comorbidity) in children is high. Most estimates suggest that between 30% and 40% of children with hearing loss have one or more additional disabilities.1 2 Coexisting conditions include cognitive disabilities, learning disabilities, cerebral palsy, autism spectrum disorders, behavioural-emotional disorders, and visual impairment. Studies have reported that the frequency of additional disabilities is similar across all levels of hearing loss, pointing to the need for children with mild or unilateral losses, as well as those with more severe losses, to receive thorough medical and developmental evaluations. 3 The diverse and complex needs of deaf or hard of hearing students with additional disabilities create challenges for teachers of the deaf.4 Educational planning and service provision require a transdisciplinary model, often with multiple specialists and extensive collaboration among teachers and other professionals, as well as families. Person-centred planning is considered to be the most effective method of education and service provision. Person-centred planning means that the child’s individual needs and strengths, rather than disability categories, drive educational placement, curriculum models and teaching strategies.

  • Why Deafblindness and Autism Spectrum Disorders Look So Much Alike
    3/15/2018 WHY DEAFBLINDNESS AND AUTISM SPECTRUM DISORDERS LOOK SO MUCH ALIKE MARCH 20, 2018 Pennsylvania Training and Technical Assistance Network (PaTTAN) Webinar Julie Maier, MA California Deafblind Services San Francisco State University Webinar description The similarities in the ways that autism spectrum disorders (ASD) and deafblindness present in children have been recognized for a long time, as have diagnostic strategies for differentiating between autism and deafness. Families and educators serving children with deafblindness increasingly hear other educators, service providers or medical specialists say that these children seem to act autistic or to have “autistic-like behaviors.” The purpose of this webinar is to look closely at the key features of ASD and deafblindness and consider why children who are deafblind might, in some cases, share many of the same features associated with ASD and how vision and hearing loss and other sensory impairments can explain these “autistic-like” features. 1 3/15/2018 In this webinar you will learn… The commonly used definitions of deafblindness and diagnostic criteria used for ASD diagnosis. The differences between sensory loss or impairment (deafblindness) and sensory processing differences (ASD). About some of key diagnostic features of ASD and compare behavioral examples of each feature with same behaviors an individual who with dual sensory loss. How neurotypical individuals also show different responses based on sensory processing, sensory regulation, and context. About some of the benefits and problems of a dual diagnosis of ASD and deafblindness.
