The impact of assistive technology and environmental interventions on function and living situation status with people who are ageing with developmental disabilities.

PURPOSE: A longitudinal study of 109 people with developmental disabilities, age 35 and older, was done to study the additive impact of mid to later life assistive technology and environmental interventions (AT-EI) on function and living situation status. All subjects were trying to transition out of institutional settings to community settings. METHOD: Functional status were measured at two times (Time I baseline and Time 2 an average of three years post intervention) on 32 functional activities under two conditions: without AT (person only) and with AT (environment adjusted). Rasch analysis was performed to convert ordinal functional scores to equal interval measures, with 95% confidence intervals computed to compare differences in function, with and without AT, across time. RESULTS: Results indicated that over 70% of subjects had better function with AT versus without AT at both time points. Over time, function did not change when rated without AT; however, when rated with AT, 13.6% had better function at Time 2. Subjects living in the community at Time 2 had significantly higher functional scores as compared to subjects in institutions, regardless of AT condition. Additional quantitative and qualitative data on AT-EI use, needs, and barriers and supports to its integration into everyday activities are reported. CONCLUSIONS: Results suggest a beneficial impact of later life AT-EI assessment and programming for people who are ageing with developmental disabilities, and qualitatively point to the influence of the social and physical living context upon AT-EI use and relationship to community living decisions long term.

Telehealth home health applications for adults with developmental disabilities.

Telehealth technology for application in home healthcare for adult persons with developmental disabilities was examined. Utilization of telehealth by clinicians, including the physician, nurse and physician assistant, physical therapist, occupational therapist, speech language pathologist, the dietitian, and psychologist for the healthcare needs of adults with developmental disabilities is discussed. Such utilization results in improved access to needed health services by reducing time and distance for this population. A telehealth model is offered, as are shifts in healthcare using telehealth technology in home health.

A survey of oral health in a population of adults with developmental disabilities: comparison with a national oral health survey of the general population.

During 1991, an oral health assessment of 101 adults with developmental disabilities aged from 21 to 53 years was undertaken as part of a broader health survey which also included medical, psychological and nutritional assessments. The study group consisted of a random sample of adults chosen from the developmentally disabled population known to be living in the lower North Shore area of Sydney. This paper describes the results of the oral health assessment and compares them with an oral health survey of the Australian population done in 1987/88. Forty-six per cent of the study group were males (mean age 33.5 years) and 54 per cent were females (mean age 33.0 years). Compared with similar age subgroups in the Australian population, the following factors were more frequently reported in the developmentally disabled group: a dental visit in the last 12 months (65 per cent vs 50 per cent; Odds Ratio (OR) 1.9:95 per cent Confidence Interval (CI): 1.3-2.8); use of public rather than private dental services (42 per cent vs 6 per cent; OR 11.3:95% CI 7.5-16.9); oral mucosal pathology requiring treatment (15 per cent vs 2 per cent; OR 8.5:95% CI 5.2-13.8); severe periodontal disease (16 per cent vs 3 per cent; OR 6.9:95% CI 4.2-11.4); and moderate to severe malocclusion (26 per cent vs 11 per cent; OR 2.1:95% CI 1.3-3.5). Fifty-eight per cent of subjects felt they needed no dental treatment but on examination of the oral mucosa, periodontal tissues and teeth, over 90 per cent were found to require some sort of dental treatment.

Prevalence of mental retardation and developmental disabilities: estimates from the 1994/1995 national health interview survey disability supplements.

In 1994 and 1995, the National Health Interview Survey included a Disability Supplement (NHIS-D) to collect extensive information about disabilities among individuals sampled as part of annual census-based household interview surveys. Here we describe the development and application of operational definitions of mental retardation and developmental disabilities to items in the NHIS-D to estimate prevalence. In our analyses, we estimate the prevalence of mental retardation in the noninstitutionalized population of the United States to be 7.8 people per thousand (.78%); of developmental disabilities, 11.3 people per thousand (1.13%); and the combined prevalence of mental retardation and/or developmental disabilities to be 14.9 per thousand (1.49%). Differences in prevalence estimates for mental retardation and developmental disabilities and among people of various ages are explored.

Longitudinal assessment of play and adaptive behavior in young children with developmental disabilities.

Deficits in appropriate play have been widely documented among children with developmental disabilities. However, there has been little research on the development of play or the relation between play and adaptive behavior in such children. The present study involved a longitudinal assessment of play and adaptive behavior among 13 preschool children with developmental disabilities. Children were assessed every 6 months over a 3-year period. Assessments included standardized ratings of adaptive behavior and videotape observations during unstructured free-play times in the preschool classroom. Adaptive behavior increased by almost one standard deviation from the first to the last round of data collection. Appropriate play was observed during approximately 20% of each 30-min observation and showed little overall change over 3 years of study. Observed play was primarily functional (57%) and exploratory (28%) with less constructive (5%) and pretend (10%) play. Adaptive behavior scores were not consistently correlated with the amount or type of play. The results suggest little overall relation between appropriate play and other major domains of adaptive behavior. Implications for play-based assessment and intervention in early childhood special education are discussed.

Prevalence and health impact of developmental disabilities in US children.

OBJECTIVE: Data from the 1988 National Health Interview Survey--Child Health Supplement were used to examine the prevalence of selected developmental disabilities and their impact among children ages 0 through 17 years. DESIGN: The following conditions, identified through a structured in-person interview with a parent or other adult household member, were examined: deafness or trouble hearing, blindness, epilepsy or seizures, stammering and stuttering, other speech defects, cerebral palsy, delay in growth or development, learning disabilities, and emotional or behavioral problems. The impact was defined by measures of perceived health status, school performance and attendance, and health care utilization. RESULTS: Seventeen percent of children in the United States were reported to have ever had a developmental disability. The prevalence of the individual disabilities ranged from 0.2% for cerebral palsy to 6.5% for learning disabilities. These conditions taken together had a substantial impact on the health and educational functioning of affected children: 1.5 times more doctor visits, 3.5 times more hospital-days, twice the number of school-days lost, and a 2.5-fold increase in the likelihood of repeating a grade in school compared with children without these conditions. The extent of this impact was much greater among children with multiple disabilities or with either cerebral palsy, epilepsy or seizures, delays in growth and development, or emotional or behavioral problems. The impact on school performance was most pronounced for children reported to have learning disabilities. CONCLUSIONS: Future research efforts should be focused on ways to reduce the impact of these developmental disabilities on quality of life.

Social work early intervention for young children with developmental disabilities.

Social workers' awareness of and formal involvement in family-centered early intervention for infants and toddlers who are at risk of or who have developmental disabilities has increased considerably during the past 15 years. The functional role that social workers can play on early intervention teams and as coordinators of early intervention services is underscored by the formal recognition of the discipline in the Individuals with Disabilities Education Act. Despite the relevance of social work to early intervention, personnel often enter early intervention practice without the benefit of formal preparation related to very young children with developmental disabilities. This article provides an overview of the definition and identification of developmental disabilities, and discusses the role of and challenges to social work in early intervention.

Sterilization of minors with developmental disabilities. American Academy of Pediatrics. Committee on Bioethics.

Sterilization of persons with developmental disabilities has often been performed without appropriate regard for their decision-making capacities, abilities to care for children, feelings, or interests. In addition, sterilization sometimes has been performed with the mistaken belief that it will prevent expressions of sexuality, diminish the chances of sexual exploitation, or reduce the likelihood of acquiring sexually transmitted diseases. A decision to pursue sterilization of someone with developmental disabilities requires a careful assessment of the individual's capacity to make decisions, the consequences of reproduction for the person and any child that might be born, the alternative means available to address the consequences of sexual maturation, and the applicable local, state, and federal laws. Pediatricians can facilitate good decision-making by raising these issues at the onset of puberty.

Technology and the environment: supportive resource or barrier for people with developmental disabilities?

Findings from needs assessments and abandonment studies point to issues with health care providers, particularly in their ability to listen to the needs of the consumer and important others regarding AT-EI. Professionals need to listen to what people are telling them or, in many cases, what they are not telling them. Actions and nonverbal messages can speak very loudly. Strategies to communicate and collaborate with consumers need to be developed. Regardless of ability to communicate or the severity of the impairments the person may be experiencing, it is important to withhold judgments that may underestimate a person's potential or desire to be in control of life decisions. AT-EI service have often seen people labeled with severe or profound intellectual disabilities challenge that diagnosis after accessing a communication or access system. Likewise, a person with a severe disability has the right to supportive resources and to the same level of respect, dignity, and quality of life as any other member of society. Using the technology and adapting the environment to provide opportunities for consumers to "voice" their wishes and control their lives can be an effective strategy to collaborate. When focusing on a rights-based philosophy, recognizing the difference between physical independence (e.g., physical and/or cognitive ability to do a task by oneself) and self-care management (e.g., access to and power to manage the supportive resources to live in the community regardless of level of physical ability) is important. We all rely on supports in our lives, whether it be tools or technology to help us do a job or another person, yet when we evaluate people with disabilities, the expectation is for people to function independently [23,24]. They even receive lower scores on functional assessments if they are using a piece of technology to do an activity. By shifting the focus to management of and access to resources versus level of physical dependence or burden, health care professionals can play a role in linking people to such resources as AT-EI and related services and strategies to support community living. Such a shift in focus also enables professionals to validate interdependence; that is, the give-take relationships that people have with each other to support each other [25]. The use of AT-EI by people with developmental disabilities often involves an interdependent relationship in which another person may help set up the environment or technology and, in turn, the consumer can then reciprocate and engage in an activity or a relationship [1]. Health care professionals also need to better understand and take into consideration the social context, its influence on consumers' use or nonuse of AT-EI, and the long-term influence on community living and participation decisions [1]. Nurses can involve important others in the process by listening to and considering their needs, and ensuring that they are informed about options, the benefits of using AT-EI for the consumer and themselves, and how to set up and troubleshoot the AT-EI. In cases where important others are not supportive, health care professionals may be in a position to link the consumer with other consumers and advocacy groups such as Centers for Independent Living or Self Advocates Becoming Empowered that may offer that support as well as membership in a collective community engaged in systems change. Health care professionals can serve as a system interface by linking people to information and resources to make informed decisions [26]. Resources on developmental disability and health, common issues that may occur, and life course planning help people identify functional issues and early signs of accelerated aging and proactively use the environment and technology to stay in living situations of choice. Few health care professionals are well prepared to provide services to people with developmental disabilities as they age; a great need exists for providers of such specialized services and for proactive later-life screenings that can identify issues early and make the most use of AT-EI strategies to address aging issues [26,28]. At any given point in time in the life of people with developmental disabilities, many different professionals and systems may be involved in decisions that could include AT-EI. Medical, educational, vocational, independent living, and case management systems may all be working with the person; however, there is often limited or no communication between them, particularly as the person ages or transitions between settings. Health care professionals, even when they are working with an individual on a limited basis, can and should take on active roles in linking consumers and important others with other systems and should ensure that information about their AT-EI needs is transferred accurately between systems. Most likely, nurses may be in a role to refer a person to specialized services, whether they may be medical, rehabilitative, AT-EI-specific, or disability advocacy groups that can help support the person as they face barriers or seek out AT. Nurses may also be in a role to pass on important information about the person's health and medical status that can help to better inform AT-EI decisions to ensure the AT meets the person's needs across contexts. As an interface, nurses may assume a role as a supporting advocate for accessing resources, not as a gatekeeper who makes decisions for people. This includes referring individuals with developmental disabilities to people and groups that know how to get AT-EI, how to fund it, and how to troubleshoot it, and linking them to other people with disabilities who are sharing strategies in person and on-line. It also includes focusing beyond basic self-care and considers AT-EI strategies that enable a person to participate in high meaning activities and roles in the home and the community. Participation in activities identified as highly meaningful and important to the person, such as participating in a religious community, networking with other people on-line, gardening, or being a member of a community group, to name a few, can positively contribute to health, wellness, and quality of life; the challenge is to create and adapt the environment (social, physical, and societal) to support participation choices and control.

The role of the pediatrician in caring for children with developmental disabilities: overview.

Pediatricians can help children with developmental disabilities to reach their potential. In addition to the issues relating to direct care outlined above and in the other articles in this issue of Pediatric Annals, clinicians should advocate on a community-wide level. This includes working with neighborhood schools, community health nurses, disease-oriented volunteer groups, and neighborhood agencies to provide access to services, support, and education for children and their families. It also includes championing the cause of children with disabilities with local and state governments. Because of the respect that pediatricians command in the community, they can play a major role in the lives of these children and their families.

Language and cognitive development: a systematic behavioral program and technology for increasing the language and cognitive skills of developmentally disabled and at-risk preschool children.

Behavioral research in teaching verbal behavior to language-delayed and developmentally disabled preschool children has progressed greatly during the past 30 years. It is now possible to produce improvements in the verbal behavior of language-delayed and developmentally disabled children that previously would have been considered impossible. Not only is it possible to teach language-delayed children a wide variety of individual elements and forms of speech, such as plurals, adjectives, syntax, and grammar, but it is also possible to achieve functional language in nonverbal children and produce total recovery in some autistic and functionally mentally retarded preschool children. The results of our research with the TALK Language Development Program provide techniques, procedures, and new directions to further advance the technology of verbal behavior. First, development of a standard procedure for the analysis, reinforcement, and recording of verbal behavior provides a precise and standard method for evaluating the effect of contingencies of reinforcement on verbal behavior. Second, the TALK program, by systematizing and operationalizing the process of shaping functional language, provides a program that is relatively easily learned by therapists, teachers, speech pathologists, and others. Third, the robustness and reliability of the TALK program, as demonstrated by replication across diagnostic groups, settings, and therapists, makes it an attractive program for use with a variety of developmentally disabled children. Fourth, the identification of specific parent-child reinforcement paradigms that appear to be functionally related to language delay may facilitate research in the prevention of language delay. Finally, our research with functionally retarded children and normal infants has led to the development of a behavioral strategy and technology for the prevention of and total recovery from some cases of language delay and functional mental retardation. At least two important opportunities now exist for making a substantial social impact through the technology of verbal behavior. First, the passage of Public Law 99-457 has created a major need for effective language programs that can be used by public school teachers of handicapped preschool children. The need will increase as more programs for the birth to 3 population are mandated. This presents a major opportunity for transferring the technology of verbal behavior to other professionals who are in daily contact with young handicapped preschool children, such as teachers, speech pathologists, pediatricians, and social workers.(ABSTRACT TRUNCATED AT 400 WORDS)

Protecting the rights of the developmentally disabled: alternatives to the existing statutory and regulatory scheme.

The Developmentally Disabled Assistance and Bill of Rights Act of 1975 and related HEW regulations require each state to establish a system for the protection and advocacy of the rights of developmentally disabled persons as a condition to receiving specified federal funds. This Note contends that, under the present statutory and regulatory scheme, states and governors have broad powers to interfere with the proper functioning of protection and advocacy systems. The Note examines the principal legal remedies, contractual and constitutional, presently available to parties interested in reducing or eliminating such interference, and concludes that such remedies are ineffectual. Instead, the author proposes, the HEW regulations should be revised to strengthen the autonomy of protection and advocacy systems or, alternatively, Congress should amend the 1975 Act to provide for federal administration of such systems.

Eating difficulties in girls with Rett syndrome compared with other developmental disabilities.

Rett syndrome arises from a mutation on the X chromosome and occurs with prevalence in the general population in 1:10,000 women. Its major nutritional consequences require that health providers recognize early signs of eating difficulties and slowing of growth parameters. Retrospective record review of 44 girls, in two equal-sized groups matched by age, showed that the Rett syndrome group was significantly different, with lower body weights, more respiratory difficulties, more gastrointestinal symptoms interfering with eating, more swallowing problems, less self-feeding, and lower texture tolerance for chewy and crunchy foods compared with the developmental disability group. Microcephaly was noted for half of the Rett syndrome group compared with seven in the developmental disability group. Parents expressed concern about their child's difficulties in eating; eight of the Rett syndrome girls and 13 of the girls in the developmental disability group were reported to have a poor appetite. Distinctive features of Rett syndrome consistent with those in the literature were documented reasonably well in the nutrition assessment records. Detailed food intake information was analyzed for food texture characteristics to recognize early eating and texture tolerance problems. Recommendations were offered for conducting a thorough nutrition assessment of Rett syndrome patients, including analysis of the texture of consumed foods. Additional recommendations for improving nutrition services to those with Rett syndrome and other developmental disabilities include ruling out microcephaly, early identification of eating difficulties, with modifications in food texture as appropriate, and self-feeding goals.

Efficacy of lamotrigine in institutionalized, developmentally disabled patients with epilepsy: a retrospective evaluation.

The paper evaluates the efficacy of the newer anticonvulsant lamotrigine in a developmentally disabled patient population. A retrospective evaluation was done at two institutional centres to assess adjunctive lamotrigine (Lamictal) efficacy in a developmentally disabled population. Mean seizure frequency was compared between a 2-month pre-lamotrigine baseline period and a 2-month treatment period. A 3-month lamotrigine titration phase occurred between baseline and treatment periods. Seizure frequency data was obtained from standardized, daily seizure records. Adverse effect data was obtained from medical and nursing notes. An intent to treat analysis was performed. Data were analysed using Student's t-test for paired data. We evaluated 44 centre residents (25 male, 19 female, average age 33 +/- 11 years). Mean lamotrigine dose was 272 +/- 133 mg per day. A significant reduction in seizure frequency was noted. Seizure frequency (all seizures) was 10.1 +/- 11.2 during the baseline period vs. 5.8 +/- 7.9 seizures per month during the treatment period (P = 0.002). Thirty-two percent of patients (n = 14) had greater than a 75% reduction in seizure frequency. Twenty-three percent of patients (n = 10) had a 50-74% seizure reduction. Twenty-five percent of patients (n = 11) had less than a 50% reduction in seizures, while 20% (n = 9) had an increase in seizures. A significant reduction of 48% in generalized seizures (9.5 +/- 11.6 vs. 4.9 +/- 6.5 seizures per month, P = 0.013) was noted. Reductions in partial seizure frequency of 48% (7.9 +/- 10 vs. 4 +/- 6.6 seizures per month, P = 0.16) as well as in mixed-type seizures (19.9 +/- 9.3 was vs. 15 +/- 12.1 seizures per month, P = 0.11) were also seen; however, these changes did not reach significance. Overall, lamotrigine was well tolerated by the subject population. Adjunctive treatment with lamotrigine appears to be an efficacious and well-tolerated treatment for seizures in a significant percentage of developmentally disabled patients with epilepsy.

Distribution of FMR1 and FMR2 alleles in Javanese individuals with developmental disability and confirmation of a specific AGG-interruption pattern in Asian populations.

The number of trinucleotide repeats in the 5' untranslated regions of the FMR1 and FMR2 genes was determined by PCR in 254 Fragile XA-negative Javanese male children with developmental disabilities. The distribution of FMR1 and FMR2 trinucleotide repeat alleles was found to be significantly different in the Indonesian population with developmental disability compared to that in developmentally disabled populations in North America and Europe (p & 0.021). Sequence analysis was performed on the trinucleotide repeat arrays of the 27 individuals with FMR1 alleles in the 'grey zone' (35-54 repeats). A repeat array structure of 9A9A6A9 was found in 16 unrelated individuals with 36 repeats, confirming earlier observations in intellectually normal Japanese. We propose that this FMR1 array pattern is specific for Asian populations and that Javanese and Japanese populations arose from a single progenitor population.

Optimizing therapy of seizures in children and adolescents with developmental disabilities.

Children and adolescents with intellectual and developmental disabilities and epilepsy are a unique patient population that offers significant challenges. They are more likely to suffer lifelong intractable epilepsy with multiple seizure types than other patients with epilepsy. In addition, these patients often cannot clearly express their complaints about antiepileptic drug (AED) side effects, and the caregiver's role becomes all-important as an advocate for the patient. Finally, behavioral and psychiatric comorbidities are common and need to be considered when choosing an AED in this patient population. Our society will be judged by how we care for the most unfortunate among us.

Psychotherapy with the developmentally disabled adolescent.

Methods of psychotherapeutic intervention with developmentally disabled adolescents are described. The need to consider the cognitive deficits of these individuals is noted. Therapeutic techniques, utilizing primarily a direct teaching approach and involving a great deal of behavioral rehearsal and repetition, are described. Clinical material is presented to illustrate the use of these procedures when problematic behavior stems from a negative self-image, faulty judgement, poor impulse control, or a failure to attain emotional independence. It is suggested that the therapists must focus on the specific problematic aspects of the adolescent's life that are in need of change and should take a position as to the nature and direction of such change.

Prelinguistic predictors of language growth in children with developmental disabilities.

This study followed 18 children with developmental disabilities, whose chronological ages were between 3 years and 6 years at the start of the study, over a 2-year period. At initial observation, children communicated primarily through prelinguistic gestures, vocalizations, and single-word utterances. Children's language skills were measured every 6 months with the Sequenced Inventory of Communication Development-Revised (D. E. Hedrick, E. M. Prather, and A. R. Tobin, 1984). Prelinguistic communication rate and parental responsiveness were also measured at each observation. Development of language over time differed between participants in accordance with their entry-level communication. Hierarchical linear modeling indicated that children's level of gestural attainment, rate of communication, and parent response contingency were significant predictors of language outcome.
