Reconceptualizing Family Adaptation to Developmental Delay

This study explores accurate conceptualization of the adaptation construct in families of children with developmental delay aged 3 to 8 years. Parents' self-reported measures of adaptation and observed dyadic relationship variables were examined. Confirmatory factor analysis and longitudinal growth modeling were used to evaluate the nature of adaptational processes. Results indicate that adaptational processes vary across adaptation index, child developmental level, and parent gender. Adaptation indices did not load onto a single construct at any time point. Several adaptational processes remained stable across time, although others showed linear or quadratic change. The findings of the current study indicate that it is time for a change in how adaptation is conceived for families of children with developmental delay.

Reliability and Validity of the Pediatric Quality of Life Inventory With Individuals With Intellectual and Developmental Disabilities

The Pediatric Quality of Life Inventory (PedsQL) measures health-related quality of life, a growing area of research, particularly among individuals with disabilities. This research is necessary to fully understand the varied needs of the population and, ultimately, ensure that those needs are being met. The current study assessed the reliability and validity of the PedsQL in individuals with intellectual and developmental disabilities, including individuals with autism spectrum disorder. Participants included 359 caregivers of children, youth, and young adults with IDD. Caregivers completed the PedsQL 4.0 Generic Core Scales questions regarding the individual's physical health and the Strengths and Difficulties Questionnaire. The PedsQL achieved excellent reliability across scales, and distinguished healthy individuals from those with chronic health conditions, as well as individuals with ASD from those without. Factor analysis confirmed a 5-factor model, with moderate to high criterion validity. The PedsQL shows sound psychometric properties and may be a useful tool to measure psychosocial functioning in this population.

Trauma-informed Day Services for Individuals with Intellectual/Developmental Disabilities: Exploring Staff Understanding and Perception within an Innovative Programme

BACKGROUND

Trauma-informed care (TIC) is a systems-level philosophy of service delivery which integrates choice, collaboration, empowerment, safety and trust to create an organizational culture sensitive to trauma. This study explores staff understandings and perceptions within an innovative trauma-informed day program for individuals with Intellectual/developmental disabilities.

METHODS

Semi-structured interviews queried staff members (n = 20) regarding trauma and TIC, the integration of the five principles of TIC, associated challenges and recommendations for improvement.

RESULTS

Inductive analyses revealed reasonable understandings of trauma and TIC, highlighting factors critical to the five principles of TIC. Differences were associated with duration of employment and the presence of specialized training. Challenges with TIC emerged at different system levels: individuals, staff, management and interorganizational.

CONCLUSIONS

This study presents preliminary insight for the innovative and formative process of integrating TIC with intellectual/developmental disabilities services.

Predictors of distress and well-being in parents of young children with developmental delays and disabilities: the importance of parent perceptions

BACKGROUND

Moving from family-centred to child-centred models of service delivery can be stressful for parents as their young children with developmental delays and disabilities transition into school. The purpose of this paper was to explore and compare predictors of both distress and well-being in parents during this transition period.

METHODS

A sample of 155 mothers of 113 boys and 42 girls participated in the study. The mean age of the children was 4.9 years and their diagnoses included autism spectrum disorder (52%); unspecified intellectual disability/developmental delay (26%); Down syndrome (12%); other genetic conditions (4%) and other diagnoses (6%). Participants completed surveys primarily online focusing on child characteristics, family resources, parent coping strategies, parental distress and positive gain.

RESULTS

Multiple regression analyses were conducted to determine predictors of parent reported distress and positive gain. Parent coping variables were the strongest predictors of both positive gain and parental distress, with reframing emerging as a predictor of positive gain and parent empowerment emerging as a predictor of both greater positive gain and lower parental distress.

CONCLUSIONS

The results of this study highlight not only the importance of including positive as well as negative outcomes in research with parents but also the importance of including parent characteristics such as coping strategies (e.g. reframing and empowerment/self-efficacy) as potential predictors of outcome in such studies.

Practitioner Review: Pathways to care for ADHD - a systematic review of barriers and facilitators

BACKGROUND

Attention-Deficit/Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder starting in childhood that may persist into adulthood. It can be managed through carefully monitored medication and nonpharmacological interventions. Access to care for children at risk of ADHD varies both within and between countries. A systematic literature review was conducted to investigate the research evidence related to factors which influence children accessing services for ADHD.

METHOD

Studies investigating access to care for children at risk of ADHD were identified through electronic searches of the international peer-reviewed and grey literature. Databases were searched from inception till 30th April 2012. This identified 23,156 articles which were subjected to three levels of screening (title, abstract and full text) by a minimum of two independent reviewers. Due to the heterogeneity in the study designs, a narrative approach was used to present the findings.

RESULTS

Twenty-seven papers met the inclusion criteria; these were grouped into four main themes, with some papers being included in more than one. These were wider determinants (10 papers); identification of need (9 papers); entry and continuity of care (13 papers) and interventions to improve access (4 papers). Barriers and facilitators to access were found to operate at the individual, organisational and societal level. Limited evidence of effective interventions to improve access was identified.

CONCLUSION

This review explored the multilayered obstacles in the pathway to care for children at risk of ADHD and the lack of evidence-based interventions designed to address these issues, thereby indicating areas for service development and further evaluative research.

Cognitive Behavioral Therapy for Depressed Adults with Mild Intellectual Disability: A Pilot Study

BACKGROUND

There is a paucity of research on psychosocial treatments for depression in adults with intellectual disability (ID). In this pilot study, we explored the efficacy of a group CBT treatment that involved a caregiver component in adults with mild ID with a depressive disorder.

METHOD

Sixteen adults with mild ID and a depressive disorder participated in a 10-week group CBT treatment and 8 adults with mild ID with a depressive disorder served as a treatment as usual (TAU) control group. Adults with mild ID and caregivers completed measures of depressive symptoms, behavior problems, and social skills at pre-treatment, post-treatment, and a 3-month follow-up. Adults with mild ID also completed a series of tasks to measure their understanding of the principles of cognitive therapy pre- and post-treatment.

RESULTS

The CBT group demonstrated significant decreases in depressive symptoms and behavior problems from pre-treatment to post-treatment and these effects were maintained at a 3-month follow-up. The CBT group demonstrated significant improvements in their ability to infer emotions and thoughts based on various situation-thought-emotion pairings from pre-treatment to post-treatment.

CONCLUSIONS

Findings indicate that adults with mild ID with a depressive disorder benefitted from a group CBT treatment with a caregiver component. Moreover, adults with mild ID appeared to benefit, at least in part, from the cognitive therapy components of the treatment, in addition to the behavior therapy components.

Exposure of children with developmental delay to social determinants of poor health: cross-sectional case record review study

BACKGROUND

Research on child development in general has highlighted the importance that the family environment plays in mediating the pathway between exposure to low socio-economic position (SEP) and child well-being. While child developmental models in intellectual disability have highlighted the interplay between social context, family environment and child development, little empirical work has attempted to formally evaluate the evidence in support of specific mediating pathways between low SEP and child outcomes.

METHODS

Secondary analysis of cross-sectional confidentialized needs analysis data collected in three Primary Care Trusts in England covering a total population of 1.25 million people. Case record reviews were undertaken for 46 023 households, 2236 (4.9%) of which contained a child in the target age range with developmental delay.

RESULTS

Children with developmental delay, when compared with their non-disabled peers, were at significantly increased risk of poorer health outcomes and of being exposed to a wide range of social determinants of poor health. Controlling for between-group differences in exposure to social determinants of poor health reduced the risk of developmental delay being associated with poorer health outcomes by 45% for behaviour problems and 89% for risk of significant harm. For children with developmental delay, parenting difficulties appears to play a particularly significant role in partially mediating the effects of low SEP.

CONCLUSIONS

The findings of the present study point to the potential effectiveness of family-focused early intervention to prevent the emergence and escalation of behavioural difficulties and health problems in children with developmental delay.

Dietary aspects related to health and obesity in Williams syndrome, Down syndrome, and Prader-Willi syndrome

Background

Dietary aspects that might contribute to development of obesity and secondary conditions are not well documented in genetic subgroups associated with intellectual disability.

Objective

To describe the intake frequencies of selected foods in participants with Prader–Willi syndrome (PWS), Down syndrome (DS), and Williams syndrome (WS), and investigate the association with body mass index (BMI). To explore food-related autonomy and intake frequencies among persons with DS in different living arrangements.

Methods

Self-reported intake frequencies and measurement of plasma carotenoids and erythrocyte content of omega-3 fatty acids (FAs) were investigated in persons aged 16–42 years, with WS (n=21), DS (n=40), and PWS (n=20).

Results

A larger proportion of participants with PWS showed high-frequency intake of fruits (p=0.012) and vegetables (p=0.004), and had higher plasma carotenoids (p<0.001) compared to participants with DS and WS. Furthermore, a larger proportion of participants with WS were low-frequency consumers of fish (p=0.005), less likely to use omega-3 FA supplements (p=0.023), and had reduced erythrocyte concentrations of long-chain omega-3 FAs (p<0.001), compared to participants with PWS and DS. In DS, BMI was negatively associated with plasma carotenoids. Increased proportions of participants living in communities showed high-frequency intake of precooked meals (p=0.030), and a tendency toward high-frequency consumption of soft drinks (p=0.079), when compared to peers living with relatives. Participants in community residences were also more likely to participate frequently in food-related decisions and preparations.

Conclusions

Persons with WS had a less-favorable dietary pattern when compared to persons with PWS. A larger proportion of persons living in communities frequently consumed precooked meals and showed a tendency of high-frequency soft drink consumption. Otherwise, their intake frequencies of the investigated foods were similar to those living with relatives, but they participated more frequently in decisions and preparations of foods.

Agenesis of the corpus callosum: symptoms consistent with developmental disability in two siblings

Agenesis of the corpus callosum (AgCC) is a congenital disorder that disrupts the development of neurological structures connecting the right and left hemispheres of the brain. In addition to neurological symptoms, many individuals with AgCC demonstrate marked deficits in social, communication, and adaptive skills. This paper presents two case studies of congenital AgCC in siblings with socioemotional and behavioral symptoms consistent with developmental disability, but with notably different symptom presentations and clinical needs. Conclusions from these cases suggest that unique symptom profiles of individuals with AgCC warrant careful consideration for referral to appropriate academic and habilitative services.

Self-reported versus informant-reported depressive symptoms in adults with mild intellectual disability

BACKGROUND

Virtually nothing is known about potential differences in the types of depression symptoms reported by adults with mild intellectual disability (ID) on self-reported questionnaires as compared with the types of symptoms reported by caregivers on informant questionnaires. Moreover, little is known about how the presentation of depression among adults with mild ID varies based on socio-demographic characteristics.

METHODS

We compared findings from two self-reported questionnaires, the Self-Reported Depression Questionnaire (SRDQ) and the Glasgow Depression Scale for People with a Learning Disability (GDS), to that of an informant questionnaire of depressive symptoms, the Glasgow Depression Scale--Caregiver Supplement (CGDS), in 80 adults with mild ID. We also examined the association between age, sex, IQ and the presence of a co-occurring psychiatric disorder and frequency of affective, cognitive and somatic depressive symptoms in our sample of adults with mild ID.

RESULTS

Adults with mild ID self-reported a higher frequency of affective and cognitive depressive symptoms than staff reported on the informant measure. Staff reported a higher frequency of somatic symptoms than adults with mild ID on one of the self-reported questionnaires (GDS) and a similar frequency on the other self-reported questionnaire (SRDQ). Important differences were found in the types of depressive symptoms based on their IQ, age and presence of a co-occurring psychiatric disorder.

CONCLUSION

Informant questionnaires offer valuable information, but assessment should include self-reported questionnaires as these questionnaires add unique information about internalised experiences (affective and cognitive symptoms) of adults with mild ID that may not be apparent to caregivers. Health care providers should be made aware of the important differences in the presentation of depressive based on their IQ, age and presence of a co-occurring psychiatric disorder.

Undergraduates' perceptions of three augmentative and alternative communication modes

OBJECTIVE

To assess undergraduates' perceptions of three augmentative and alternative communication (AAC) modes.

METHOD

We showed 104 undergraduates a video clip of a person using each of the three AAC modes and asked them to rate each option in terms of perceived (a) intelligibility, (b) ease of acquisition, (c) effectiveness/acceptability, and (d) preference. The three AAC modes shown were (a) manual signing, (b) picture exchange, and (c) speech-generating device.

RESULTS

Mean ratings for perceived intelligibility and effectiveness/acceptability were significantly higher for the speech-generating device. The speech-generating device and manual signing options were rated as being more preferred over picture exchange. Picture exchange was rated significantly higher on perceived ease of acquisition.

CONCLUSION

Speech-generating devices were perceived to have greater social validity than manual signing and picture exchange.

Caregiver strain and sensory features in children with autism spectrum disorder and other developmental disabilities

Caring for children with disabilities contributes to increased levels of parent stress or caregiver strain. However, the potential relationship of sensory features to strain among caregivers of children with autism spectrum disorder (ASD) and other developmental disabilities (DD) is unknown. Sensory features include overreactions, underreactions, and unusual interests in sensations, which may negatively impact family functioning. This descriptive study confirmed three caregiver strain types (i.e., objective, subjective internalized, subjective externalized) and explored differences among ASD (n  =  71) and DD (n  =  36) groups, with the ASD group reporting higher levels. Furthermore, this study explored the contribution of sensory features to caregiver strain, finding differential contributions to strain in the ASD group and covariate contributions (i.e., child cognition, mother's education) in the DD group.

Eliciting perceptions of satisfaction with services and supports from persons with intellectual disability and developmental disabilities: a review of the literature

BACKGROUND

Assessing the perceptions of individuals with intellectual disability (ID) and developmental disabilities (DD) is an essential part of evaluating and planning services and an important component of respect for self-direction and autonomy. It can be difficult, however, to assess satisfaction in such a way that individuals with disabilities' actual perceptions of satisfaction are accurately represented because of intellectual and communication difficulties they may have, the restricted range and nature of service systems, and the limitations of strategies used by some researchers.

METHOD

The purpose of this literature review was to systematically examine research studies designed to solicit personal satisfaction information from individuals with ID and DD. We reviewed 29 studies that met inclusion criteria to determine (1) who were participants in the studies, (2) what processes researchers used to obtain opinions and perspectives of persons with ID and DD, and (3) how researchers ensured the credibility, accuracy and voluntariness of participants' responses.

RESULTS

Findings revealed that most of the research participants had ID with higher IQs and limited needs for supports. Researchers utilised a variety of processes to elicit perceptions of satisfaction. Most studies employed individual interviews; researchers addressed comprehensibility of questions in a number of ways (e.g. use of visuals, adjusting wording of questions, providing clear examples). Few studies reported training interviewers or taking into account participants' primary language or cultural background. No studies reported educating participants about how to understand the satisfaction information data or how to use it in advocating for more appropriate supports.

CONCLUSIONS

Assessing the satisfaction with supports and services of individuals with ID and DD is complex particularly for persons with extensive support needs. Continued research using varied conceptual frameworks and new technologies is needed. Also helpful will be teaching persons with disabilities about the assessment process and how to use its results.

Toward impacting medical and psychiatric comorbidities in persons with intellectual/developmental disabilities: an initial prospective analysis

OBJECTIVE

The purpose of this study was to determine the effectiveness of psychiatric medical services, counseling, and behavioral treatments for adult patients with intellectual disabilities plus behavioral disorders and/or emotional distress.

METHODS

Behavioral and medical data were collected at six and 12 months for a consecutive series of 141 adult patients with mild, moderate, or severe/profound intellectual disabilities who had been referred to a dual diagnosis mental health clinic, and treatment outcomes were compared.

RESULTS

Most improvement in behavioral problem severity occurred at six months, then plateaued. Treatment improvement for subjects with anxiety disorders was statistically significant across all interventions. In this sample, as expected, patients with intellectual disability had higher incidences of medical illnesses than the general population.

CONCLUSIONS

Subjects with more behavioral (overt) symptoms tended to receive referrals for behavioral support, and subjects with less overt symptoms were referred to counseling. In a follow-up study, similar individuals with moderate intellectual disabilities will be seen psychiatrically, but then randomly assigned to either supportive counseling or behavior support, or both. They will be followed prospectively, to determine the relative benefits of supportive psychotherapy, behavior support, or a combination, and for what duration of time the treatment should be continued.

Parental and practitioner perspectives on raising an adolescent with a disability: a focus group study

PURPOSE

To examine the challenges faced by parents of teenagers with a disability to determine the need for a tailored parenting program for this population.

METHOD

Focus groups were conducted with six parents and nine practitioners with experience supporting parents of teenagers with a disability.

RESULTS

An inductive thematic analysis revealed close agreement between parents and practitioners and eight understandable and relevant themes. The results indicated that parents have difficulty planning and facilitating transitions for their adolescent children, managing behavioural problems due to these problems being unique to this developmental period and because some of the parenting strategies that were useful when their children were younger were no longer applicable. High levels of stress and feelings of grief were also described.

CONCLUSIONS

These results suggest that parents of adolescents with a developmental disability could benefit from a parenting program and that an existing evidence-based parenting program should be modified. Implications for program design for this population are discussed.

IMPLICATIONS FOR REHABILITATION

Parents have difficulty supporting their teenagers' behaviour. Some parenting strategies that were useful for young children are no longer applicable. Parents may benefit from a parenting program tailored for teenagers.

Effect of supported employment on vocational rehabilitation outcomes of transition-age youth with intellectual and developmental disabilities: a case control study

The purpose of this study was to examine the effect of supported employment intervention on the employment outcomes of transition-age youth with intellectual and developmental disabilities served by the public vocational rehabilitation system using a case-control study design. Data for this study were extracted from the Rehabilitation Services Administration Case Service Report (RSA-911) database for fiscal year 2009. The sample included 23,298 youth with intellectual and developmental disabilities aged between 16 and 25 years old at the time of application. The classification and regression tree (CART) method was used to estimate propensity scores and to adjust for selection bias on the basis of all prominent covariates relevant to the dependent variable (i.e., competitive employment). Results yielded six homogeneous subgroups, and receipt of supported employment was found to increase the employment rates across all of the groups. The effect of supported employment was especially strong for youth who were Social Security beneficiaries, special education students, and individuals with intellectual disabilities or autism who were high school graduates. These findings suggest that supported employment is an effective service for enhancing the vocational rehabilitation outcomes of young adults and provides valuable information for policy makers, health care providers, rehabilitation counselors, and educators.

The individual supported living (ISL) manual: a planning and review instrument for individual supported living arrangements for adults with intellectual and developmental disabilities

BACKGROUND

Following the closure of large residential facilities over the past several decades, emphasis on community living for adults with developmental disabilities has strengthened. However, the concept of community living is ambiguous. The term is often associated with congregation of people with disabilities in ordinary houses 'in' the community. Group homes, the most common contemporary formal expression of 'community living', may use ordinary houses and accommodate a small number of residents comparable to a large family. Individual supported living (ISL) arrangements around a single person with a disability using person-centred principles are occurring with increasing frequency. The ISL manual was developed over 4 years in two sequential research projects to produce a quality framework articulating ISL and operationalising the framework into a review and planning instrument for ISL arrangements.

METHOD

The ISL manual was developed in three stages and overseen by a reference group of key stakeholders purposively recruited as well-versed in ISL. The first stage operationalised the quality framework over two half-day workshops with a group of key informants. Participants identified indicators and sources of evidence for each attribute of the quality framework. The quality framework, indicators, and sources of evidence were compiled into an initial evaluation instrument of nine themes consisting of 27 attributes. This was piloted in two rounds to enhance the utility of the instrument and develop the final manual which contained eight themes and 21 attributes. A comprehensive literature search was carried out to identify relevant empirical ISL studies.

RESULTS

The literature search identified four empirical studies that incorporated ISL over the preceding 3 years. A previous literature search from the first research project that produced the quality framework spanned 27 years and identified five empirical studies. We concluded that the empirical base for developing evidence for the nature and outcomes of ISL arrangements was sparse. The ISL manual and scoring booklet developed in the current research project includes six illustrative case studies of ISL, instructions for potential users to review living arrangements or set up a new arrangement, and the review framework consisting of descriptions of themes and attributes, indicators, and sources of evidence.

CONCLUSIONS

The dearth of empirical studies of ISL arrangements for people with developmental disabilities, despite increased policy emphasis on individualised options, underscores the importance of planning and review tools to promote quality outcomes. The ISL manual can assist adults with developmental disabilities, families, carers, and service providers to plan and review ISL arrangements. Further research will enhance the properties of this instrument and establish the relationship between quality of ISL arrangements and outcomes such as quality of life, and participation and inclusion.

Variables associated with the use of complete oral calorie supplements in children with feeding problems

OBJECTIVE

To examine child and parent variables associated with complete oral calorie supplement use among children with feeding problems.

DESIGN

Correlational examination of data from patient intake surveys.

SETTING

Hospital-based feeding program.

PARTICIPANTS

Participants included 281 parents of children referred to a hospital-based feeding clinic, including 114 who received supplements (70.2% boys; mean age, 60.1 months) and 167 who did not receive (79.6% boys; mean age, 67.5 months).

VARIABLES MEASURED

Children's age, gender, weight status, diagnostic category (no special needs, autism, or other special needs), supplement intake, oral motor problems, child mealtime behavior (using the Child Eating Behavior Questionnaire), parent feeding practices (using the Parent Mealtime Action Scale), and diet variety for child and parent.

ANALYSIS

Chi-square analyses compared children who did and did not receive supplements for their percentage of gender, diagnostic, and weight status categories; t tests or Mann-Whitney U tests compared children who did and did not receive supplements, for age, oral motor problems, children's mealtime behavior, parent feeding practices, and diet variety.

RESULTS

Compared with children who did not receive nutritional supplements, those who did were younger (P < .01) and more underweight (P < .001), and showed less Food Responsiveness (P < .001), less Food Enjoyment (P < .001), more Food Satiety (P < .001, and more Slow Eating (P < .001), and their parents were more likely to use Insistence on Eating (P < .001).

CONCLUSIONS

Whereas supplement use was related to underweight, 78.2% of children receiving them were normal weight or overweight, which suggests that supplements are being used to address mealtime selective eating. The use of supplements should be considered carefully because they do not appear to increase diet variety and may increase the chance of overweight over time.

Family routines within the ecological niche: an analysis of the psychological well-being of U.S. caregivers of children with disabilities

Using mixed methods, this study examined the relationship of caregivers of children with disabilities' psychological well-being (PWB) and their orchestration of daily routines within their ecological niche. Thirty-nine U.S. caregivers completed in-depth interviews, PWB Scales, and Family Time and Routines Index (FTRI). We used a multi-step analysis. Interview data was coded and vignettes created without knowledge of PWB and FTRI ratings. Next, the relationship of quantitative measures was analyzed. Four groups were created using FTRI-extent and PWB means: (1) low routine-low PWB, (2) low routine-high PWB, (3) high routine-low PWB, and (4) high routine-high PWB. We examined qualitative differences in key features between groups.

FINDINGS

Total PWB and FTRI scores were not significantly correlated, PWB Purpose in Life and FTRI-extent scores were moderately positively correlated, and PWB Environmental Mastery and FTRI-extent correlation approached significance. Qualitative findings describe caregivers' structuring of routines, intensity of oversight, support in routines, management of dinner, paid work, and needs for respite. The four groups differed in paid work, household support, degree the child could self-occupy, Environmental Mastery, and opportunities to recuperate. Caregivers with higher levels of well-being and more regular routines did paid work, had supportive spouses, had children who more often could follow routines, had higher Environmental Mastery, could orchestrate a family meal, and had breaks from care in either work or leisure. All Native American caregivers and Mexican American caregivers with spouses were in the high routine-high PWB group. Insight into this complex negotiation between family members within daily routines may provide practitioners a better understanding of how to work within family circles to foster therapeutic alliances, identify focused intervention targets, and promote positive family wide outcomes.

A review of pain measures for hospitalized children with cognitive impairment

PURPOSE

The aims of this review were to examine pain measures for hospitalized children with cognitive impairment who are unable to self-report and to describe the best available evidence for their clinical utility in acute care settings.

DESIGN AND METHODS

Electronic searches to identify published evidence were conducted and studies reviewed. Reported psychometrics and feasibility of the Non-Communicating Child's Pain Checklist-Postoperative Version, Individualized Numeric Rating scale, Pediatric Pain Profile, and revised Face, Leg, Activity, Cry, and Consolability scale were examined.

CONCLUSIONS

These four measures have established validity and reliability. However, clinical utility findings varied.

PRACTICE IMPLICATIONS

The revised Face, Leg, Activity, Cry, and Consolability scale has demonstrated feasibility in acute care settings related to ease of use, time requirements, and flexibility regarding caregiver input.

Neurodevelopmental disabilities in children with intermediate and premutation range fragile X cytosine-guanine-guanine expansions

To determine the range of neurodevelopmental diagnoses associated with intermediate (45-54 repeats) and premutation (55-200 repeats) range cytosine-guanine-guanine fragile X expansions, the medical records of children with intermediate or premutation range expansions were retrospectively reviewed, and all neurodevelopmental diagnoses were abstracted. Twenty-nine children (9 female, 20 male; age, 13 months to 17 years) with intermediate (n = 25) or premutation (n = 4) range expansions were identified with neurodevelopmental diagnoses, including global developmental delay/intellectual disability (n = 15), language and learning disorders (n = 9), attention-deficit hyperactivity disorder (n = 5), epilepsy (n = 5), and motor disorders (n = 12), including 2 boys younger than 4 years of age with tremor and ataxia. Thus, children with intermediate or premutation range fragile X cytosine-guanine-guanine expansions may be more susceptible than children without such expansions to other processes, both genetic and environmental, that contribute to neurodevelopmental disability.

Mixed-reality exercise effects on participation of individuals with spinal cord injuries and developmental disabilities: a pilot study

OBJECTIVE

The purpose of this pilot study was to investigate the effectiveness of a mixed-reality (MR) exercise environment on engagement and enjoyment levels of individuals with spinal cord injury (SCI) and intellectual and developmental disabilities (IDD).

METHODS

Six people participated in this cross-sectional, observational pilot study involving one MR exercise trial. The augmented reality environment was based on a first-person perspective video of a scenic biking/walking trail in Colorado. Males and females (mean age, 43.3 ± 13.7 years) were recruited from a research database for their participation in previous clinical studies. Of the 6 participants, 2 had SCI, 2 had IDD, and 2 were without disability. The primary outcome measurement of this pilot study was the self-reported engagement and enjoyment level of each participant after the exercise trial.

RESULTS

All participants reported increased levels of engagement, enjoyment, and immersion involving the MR exercise environment as well as positive feedback recommending this type of exercise approach to peers with similar disabilities. All the participants reported higher than normal levels of enjoyment and 66.7% reported higher than normal levels of being on a real trail.

CONCLUSION

Participants' feedback suggested that the MR environment could be entertaining, motivating, and engaging for users with disabilities, resulting in a foundation for further development of this technology for use in individuals with cognitive and physical disabilities.

Toddlers with Williams syndrome process upright but not inverted faces holistically

Holistic processing of upright, but not inverted, faces is a marker of perceptual expertise for faces. This pattern is shown by typically developing individuals beginning at age 7 months. Williams syndrome (WS) is a rare neurogenetic developmental disorder characterized by extreme interest in faces from a very young age. Research on the effects of inversion on holistic processing of faces by older children and adults with WS has produced mixed results. Younger children with WS were not included in these previous studies. Using the habituation switch paradigm, we demonstrated that 15-35-month-olds with WS process upright, but not inverted, faces holistically. This study provides evidence of perceptual expertise for faces in individuals with WS early in life.

Mindfulness-based stress reduction for parents of young children with developmental delays: implications for parental mental health and child behavior problems

BACKGROUND

Parents of children with developmental delays (DD) typically report elevated levels of parental stress compared with parents of typically developing children. Children with DD are also at high risk for exhibiting significant behaviour problems. Parental stress has been shown to impact the development of these behaviour problems; however, it is rarely addressed in interventions aimed at reducing child behaviour problems. The current study examined the efficacy of mindfulness-based stress reduction (MBSR) for parents of children with DD by investigating whether this intervention is effective in reducing parenting stress and whether decreases in parenting stress lead to reductions in behaviour problems among children with DD.

MATERIALS AND METHODS

Forty six parents of children with DD were randomly assigned to an immediate treatment or wait list-control group. Participants completed questionnaires assessing parental stress and child behaviour problems at intake and at a second assessment, which took place after only the immediate treatment group had received the MBSR.

RESULTS

Parents who participated in MBSR reported significantly less stress and depression as well as greater life satisfaction compared with wait list-control parents. Regarding child outcomes, children whose parents participated in MBSR were reported to have fewer behaviour problems following the intervention, specifically in the areas of attention problems and ADHD symptomatology.

DISCUSSION

Results indicated that MBSR may be an effective intervention for ameliorating parental stress and mental health problems among parents of children with DD. Additionally, these benefits may 'spill over' and improve behaviour challenges among these children.
