Behavioral Approaches to Assessment and Early Intervention for Severe Problem Behavior in Intellectual and Developmental Disabilities

How Does Sleep Deprivation Functionally Impact the Challenging Behavior of People With Intellectual Disabilities? A Systematic Review

Sleep deprivation is a common health condition among people with intellectual disabilities. Studies have linked sleep problems with challenging behaviors. However, it is unclear if there is a consistent effect on challenging behavior and what reinforcement mechanism(s) might be involved. A systematic review of PsychINFO, PubMed, and Scopus identified seven studies meeting the inclusion criteria that had been published over the past 50 years. Data were extracted regarding participant characteristics, specific aim, sleep deprivation, functional behavioral assessments, results, and key findings. Studies consistently reported increased rates of challenging behavior following bouts of sleep deprivation. Five of the seven studies demonstrated negative reinforcement as the mechanism associated with increased challenging behavior. Results were unclear or lacking for other reinforcer mechanisms. Current evidence shows that sleep deprivation can increase negatively reinforced challenging behavior, but automatic and positive reinforcement mechanisms may be unaffected. Theoretical and practice implications are discussed.

Pharmacological treatment in autism: a proposal for guidelines on common co-occurring psychiatric symptoms

BACKGROUND

The prevalence of autism spectrum disorder (ASD) has surged, with an estimated 1 in 36 eight-year-olds in the United States meeting criteria for ASD in 2020. Autistic individuals face elevated rates of co-occurring medical, psychiatric, and behavioral conditions compared to non-autistic individuals. The rising ASD-patient demand is increasingly outpacing the capacity of ASD-specialty clinics, resulting in urgent need for autism-competent providers in general practice settings. This work aims to empower healthcare providers, especially primary care providers (PCPs), with guidelines for the recognition and safe pharmacologic management of common co-occurring psychiatric and behavioral conditions in ASD.

METHODS

Lurie Center for Autism medical providers, who have extensive experience in ASD care, delineated approaches for recognition and pharmacological treatment of sleep disturbances, attention-deficit/hyperactivity disorder (ADHD), anxiety, depression, and irritability tailored to ASD patients. Pharmacological guidelines were iteratively refined until consensus was reached. Treatment differences relative to standard of care (SOC) of non-autistic individuals are noted. Key literature and clinical trial results were reviewed to supplement clinical experience.

RESULTS

The pharmacological treatment pathways reflect how appropriate medication options for ASD patients can depend on many factors unique to the patient and can differ from established non-autistic SOC. Key takeaways include: For sleep disturbances in ASD, initial strategies align with non-autistic SOC, emphasizing sleep hygiene and melatonin use. First-line recommendations for treating ADHD, anxiety, and depression in ASD differ from non-autistic SOC; α2-adrenergic agonists are more suitable than stimulants for some ASD-ADHD patients, buspirone and mirtazapine are preferred to selective serotonin reuptake inhibitors (SSRIs) for anxiety, and duloxetine, mirtazapine, bupropion, and vortioxetine are recommended ahead of SSRIs for depression. Addressing irritability in ASD requires interdisciplinary evaluation of contributing factors, and guanfacine, risperidone, or aripiprazole may be appropriate, depending on severity.

CONCLUSIONS

Recognition and treatment of co-occurring psychiatric and behavioral conditions in autistic patients must account for differences in clinical presentation and medication effectiveness and tolerability. Drawing on evidence-based clinical insights, these guidelines seek to support PCPs in making informed decisions when prescribing medications for ASD patients with co-occurring psychiatric and behavioral conditions, ultimately enhancing access to timely, comprehensive care for all individuals with ASD.

Validating social reinforcer classes for low-severity challenging behavior identified by sensitivity tests

Behavior analysts typically assess and treat challenging behavior after it occurs regularly and at high severity. Although effective, this reactive approach is quite costly and resource intensive. A growing literature supports an alternative preventive approach; the first step involves conducting sensitivity tests to screen the topographies and functions of low-severity behavior evoked by establishing operations commonly included in challenging behavior research (e.g., Fahmie et al., 2020). Despite the potential value of sensitivity tests, their correspondence with functional analyses has yet to be established. This study measured the correspondence between social reinforcer classes nominated by sensitivity tests and social reinforcer classes verified by traditional functional analysis outcomes of the same behaviors. Participants included 10 young autistic learners who were reported to exhibit low-severity challenging behavior. Data showed generally high correspondence between both assessment outcomes for challenging behavior but not for appropriate requests.

Comparison of the Effectiveness of Online and Face-to-Face Parent Training for Parents of Children With Developmental Disabilities

BACKGROUND

Parent training (PT) is an effective intervention for improving children's behavioral problems and enhancing parental mental health in those caring for children with developmental disabilities (DD). Recent studies report the effectiveness of online PT (ON-PT). ON-PT encompasses both the on-demand type and the real-time type, which involves real-time online group PT delivered through web conferencing systems. However, the efficacy of the on-demand type has been established through comparisons with face-to-face PT (F2F-PT), whereas the real-time type of ON-PT has been assessed exclusively in single-arm studies, underscoring the need for comparative analyses with F2F-PT to validate its effectiveness. This study aims to compare the effectiveness of the real-time type of ON-PT and F2F-PT for parents of children with DD using a retrospective study design.

METHODS

The analysis included data from 13 parent-child pairs in the F2F-PT and 27 parent-child pairs in the ON-PT. Assessment scales included parental depression and stress, evaluated using the Beck Depression Inventory-Second Edition (BDI-II) and Parenting Stress Index (PSI), respectively, as well as children's behavioral problems, measured with the Eyberg Child Behavior Inventory (ECBI). A two-way repeated-measures ANOVA assessed the impact of different PT delivery methods and time on the outcome variables.

RESULTS

Attendance and dropout rates were similar between ON-PT (82%, 18.7%) and F2F-PT (80.3%, 18.1%). A two-way repeated-measures ANOVA showed that the interaction effect was marginally significant for PSI (p = 0.066) and statistically significant for both the child domain of PSI (p = 0.049) and ECBI (p = 0.013). Simple main effects analysis indicated that pre-test mean scores for PSI (p < 0.001), the child domain of PSI (p = 0.001), and ECBI (p = 0.002) were significantly higher than post-test scores in the ON-PT compared with the F2F-PT. Furthermore, although a higher proportion of participants in the ON-PT were within the clinical range of ECBI at the pre-test (70.4%) compared to the F2F-PT, this proportion decreased to 44.4% at the post-test.

CONCLUSION

This study suggests that ON-PT may be as effective as or potentially more effective than F2F-PT. The adoption of online formats should be considered for families facing challenges, as ON-PT may improve children's behavioral problems and reduce parental stress. Nonetheless, the retrospective study design warrants caution in interpreting the findings, and a future study with a prospective, rigorous validation design will be essential to effectively compare the effectiveness of ON-PT and F2F-PT.

Behavioural phenotype of SYNGAP1-related intellectual disability

BACKGROUND

SYNGAP1- related intellectual disability (SYNGAP1-ID) is a rare genetic disorder presenting with intellectual disability (ID), epilepsy, maladaptive behaviours and communication challenges. To date, few studies have assessed the context in which these maladaptive behaviours occur. This study aims to investigate the prevalence of problem behaviours, characterise the behavioural phenotype and use well-validated measures to explore variables that maintain the behaviours.

METHODS

Our sample includes 19 individuals diagnosed with SYNGAP1-ID and their parents. Parents provided information on behaviours that their children engage in, as well as their general behavioural dispositions. Well-validated measures (e.g., the Repetitive Behaviour Scale-Revised, Sensory Profile-2 and Vineland Adaptive Behaviour Scale) were used. A subset of individuals underwent further direct experimental assessment of their problem behaviour to identify the variables maintaining those problem behaviours. Parental reports were analysed using nonparametric statistical analysis; the direct assessments of individuals' problem behaviour were analysed using visual analysis and validated supplemental measures.

RESULTS

All 19 individuals engaged in some form of maladaptive problem behaviour. Ratings of ritualistic, sameness and restricted behaviours measured by the RBS-R were commensurate with individuals diagnosed with idiopathic autism spectrum disorder (ASD) while self-injurious behaviours were endorsed at a higher level in SYNGAP1-ID when compared with idiopathic ASD. The problem behaviours in our cohort of patients with SYNGAP1-ID were maintained by automatic reinforcement and social attention and are positively correlated with atypical sensory responses.

CONCLUSIONS

Individuals with SYNGAP1-ID engage in problem behaviours commensurate with other populations (e.g., those with ASD), they exhibit atypical response to sensory stimuli. Problem behaviours were frequently maintained by automatic reinforcement, which may result from a dysregulated sensory system. Children with SYNGAP1-ID may benefit from strategies used in persons with ASD.

Youth Crisis: The Current State and Future Directions

The number of children and youth experiencing behavioral health crisis in the United States is substantially increasing. Currently, there are shortages to home-based and community-based services as well as psychiatric outpatient and inpatient pediatric care, leading to high emergency department utilization. This article introduces a proposed crisis continuum of care, highlights existing evidence, and provides opportunities for further research and advocacy.

Emergency Department Utilization Due to Challenging Behavior in Children and Adolescents Diagnosed with Autism Spectrum Disorder

Children and adolescents with autism spectrum disorder (ASD) are at a greater risk of seeking emergency department (ED) services during behavioral crises, such as acute aggression, suicidal or homicidal ideation, self-injury, or other types of challenging behavior (e.g., pica, dangerous behaviors). Research demonstrates children and adolescents with ASD often return to the ED due to challenging behavior, suggesting that gaps in care exist (e.g., follow-up appointments, referrals). However, the current knowledge basis is largely based on data from other countries. Given the unique landscape of healthcare in the United States, it is prudent to elucidate characteristics of children and adolescents with ASD who are seeking emergency care due to challenging behavior, as well as systems-level factors that both contribute to our understanding of challenging behavior and ASD in ED settings. In this study, we focus on frequency and characteristics of children and adolescents with ASD presenting to the ED with challenging behavior over the course of a 6-year period in the Midwest region of the United States. Clinical implications for ED staff are discussed.

Survey of rehabilitation approaches and plans for individuals with dravet syndrome (RAPIDS) in Italy: Current practices and strategies to progress

Dravet syndrome, a developmental and epileptic encephalopathy, manifests with varying degrees of cognitive and communication impairment, postural and movement disorders (such as ataxia, coordination issues, and crouch gait) and behavioural challenges (including attention deficit/hyperactivity, oppositional/defiant behaviour, and autistic traits). Rehabilitation is a valuable tool for most patients, typically prescribed to address the most pressing issues. However, current practices often fall short in proactively preventing and treating known challenges associated with the syndrome, as indicated by the latest literature, at different life stages. Furthermore, there is a notable lack of evidence regarding treatment types and efficacy specific to people with Dravet Syndrome. Conducted in collaboration with one of the Italian Patient associations, this national survey provides a comprehensive view of the rehabilitation landscape in Dravet Syndrome, as perceived by caregivers. It outlines the types of treatments for 51 patients, based on age and relevant clinical features. The findings reveal a heterogenous rehabilitation approach, only partly tailored to the presence of specific comorbidities, and underline numerous unmet needs. Compared to the past there is indirect evidence that more patients are offered early rehabilitation. Nonetheless, while nowadays speech therapy and neuropsychomotor therapy are nearly universal for children up to the age of 10, some begin physiotherapy and psychotherapy thereafter, with a majority discontinuing treatments. Therefore, families of adolescent and adult patients often face a lack of comprehensive support, predominantly offered when epilepsy is more challenging to control affecting rehabilitation adherence and effectiveness. Finally, a negligible minority is offered treatments such as neurovisual training, augmentative and alternative communication, and occupational therapy. Many of these considerations could apply to other developmental and epileptic encephalopathy with lifelong disability. This survey calls for more data collection on this important topic for more efficient allocation of rehabilitation resources.

Mental and Behavioral Health, and Crisis Services for People with Intellectual and Developmental Disabilities in Medicaid Home- and Community-Based Services

People with intellectual and developmental disabilities (IDD) often have higher rates of comorbid mental health conditions compared to the general population. Yet, many people with IDD also have unmet needs for mental and behavioral health services. The aim of this study was to examine how states provided mental and behavior health, and crisis services to people with IDD in their Home- and Community-Based Services (HCBS) programs, the largest funding mechanism for Long-Term Services and Supports (LTSS) for people with IDD in the United States. We analyzed fiscal year (2021) Medicaid HCBS waivers for people with IDD from across the United States to examine if and how they provided mental and behavior health, and crisis services. States projected spending $968.9 million for mental and behavior health, and crisis services for 190,299 people with IDD. Applied behavior analysis services were provided at greater rates than positive behavior supports and other forms of behavior interventions. While most states provided mental and behavior health, and crisis services in their waivers, there were vast inconsistencies in how they did so, across states, waivers, and services. HCBS are a crucial safety net to ensure people with IDD, especially those who also have mental health disabilities, can live and thrive in their communities.

Toward Maximizing Assessment Efficiency: A Synthesized Trial-Based Functional Analysis and Competing Stimulus Assessment

Despite the success of the standard functional analysis (FA), some limitations to conducting an FA in practice include time, resources, ecological relevance, and safety, which have led to the development of procedural adaptations such as trial-based and synthesized FA formats. The purpose of this case study was to identify the function(s) of self-injurious behavior (SIB) for a 3-year-old female with developmental disabilities using a brief trial-based FA with ecologically relevant synthesized contingencies, based on caregiver input, to minimize opportunities for SIB. We identified that positive physical attention likely functioned, at least in part, as a reinforcer for SIB, in less than 42 min. Overall harm to the child as a result of the synthesized trial-based FA was minimal, and the caregiver viewed the modified conditions favorably. We then assessed the role of competing stimuli on SIB rates with the child's mother and identified two potential items that may compete with attention as a reinforcer for SIB. Our findings highlight the utility and importance of individualized assessment as the first step in the safe treatment of severely challenging behavior.

Pilot study of a real-time early agitation capture technology (REACT) for children with intellectual and developmental disabilities

Objective

Children and adolescents with intellectual and developmental disabilities (IDD), particularly those with autism spectrum disorder, are at increased risk of challenging behaviors such as self-injury, aggression, elopement, and property destruction. To mitigate these challenges, it is crucial to focus on early signs of distress that may lead to these behaviors. These early signs might not be visible to the human eye but could be detected by predictive machine learning (ML) models that utilizes real-time sensing. Current behavioral assessment practices lack such proactive predictive models. This study developed and pilot-tested real-time early agitation capture technology (REACT), a real-time multimodal ML model to detect early signs of distress, termed "agitations." Integrating multimodal sensing, ML, and human expertise could make behavioral assessments for people with IDD safer and more efficient.

Methods

We leveraged wearable technology to collect behavioral and physiological data from three children with IDD aged 6 to 9 years. The effectiveness of the REACT system was measured using F1 score, assessing its usefulness at the time of agitation to 20s prior.

Results

The REACT system was able to detect agitations with an average F1 score of 78.69% at the time of agitation and 68.20% 20s prior.

Conclusion

The findings support the use of the REACT model for real-time, proactive detection of agitations in children with IDD. This approach not only improves the accuracy of detecting distress signals that are imperceptible to the human eye but also increases the window for timely intervention before behavioral escalation, thereby enhancing safety, well-being, and inclusion for this vulnerable population. We believe that such technological support system will enhance user autonomy, self-advocacy, and self-determination.

A review of the use of psychotropic medication to address challenging behaviour in neurodevelopmental disorders

Engagement in challenging behaviour (e.g., aggression, self-injury) is reported to occur in neurodevelopmental disorders such as intellectual disabilities (ID), autism spectrum disorder (ASD), and fragile X syndrome (FXS). Common interventions to address these behaviours include both behavioural and pharmacological approaches. Although psychotropic medications are commonly used to address challenging behaviour in ID, ASD, and FXS, demonstration of the effectiveness of treatment is limited. Furthermore, research examining interaction effects between psychotropic medication, challenging behaviour, and environmental events within specific neurodevelopmental disorders such as ID, ASD, and FXS is scarce. The purpose of this chapter is to provide an overview of challenging behaviour within ID, ASD, and FXS and of the effectiveness of psychotropic medication as an intervention for challenging behaviour within these neurodevelopmental disorders. Finally, research examining how psychotropic medication may impact the relationship between challenging behaviour and environmental events is reviewed.

Applied Behavior Analysis and the Abolitionist Neurodiversity Critique: An Ethical Analysis

The behavior analytic literature on neurodiversity remains limited. This article aims to begin filling the lacuna. We will introduce the neurodiversity perspective and demonstrate an important congruence between the behavior analytic and neurodiversity perspectives on autism. Despite this congruence, applied behavior analysis is often targeted for criticism by proponents of the neurodiversity perspective. A central concern raises questions about the aims of behavior analytic interventions for clients with autism. Is it appropriate to teach clients with autism to behave as if they were neurotypical? Concerns about the aims of behavior analytic interventions mirror concerns that have been raised about the aims of language education in schools. Drawing on the literature regarding linguistically diverse classrooms, we will critically evaluate the abolitionist neurodiversity critique of ABA. We conclude by considering both concrete and theoretical implications for the ethics of behavior analytic work with autistic clients.

DDX3X Syndrome: Summary of Findings and Recommendations for Evaluation and Care

DDX3X syndrome is a surprisingly common newly discovered genetic neurodevelopmental disorder associated with intellectual disability, autism spectrum disorder, language delays, attention-deficit/hyperactivity disorder, and medical comorbidities. Two hundred individuals with DDX3X syndrome have been described in the literature to date, with varied levels of detail. Individuals with DDX3X syndrome often have complex presentations including symptoms in the neurological, psychiatric/psychological, ophthalmologic, and gastrointestinal domains. Owing to this complex presentation, an overview of symptom prevalence, medical recommendations, and suggested medical surveillance is vital for the care and health of individuals with DDX3X syndrome. In this article, we summarize the present clinical knowledge of DDX3X syndrome and provide recommendations for clinical assessments and care based on a comprehensive review of the existing literature and of new, not yet published DDX3X syndrome cohorts. As more is learned about DDX3X syndrome, we anticipate that these recommendations will evolve.

Challenging behaviour in students with intellectual disabilities: the role of individual and classmates' communication skills

BACKGROUND

Children and adolescents with intellectual disabilities (ID) are at increased risk of developing challenging behaviour. Challenging behaviour may be partially explained by low individual communicative competences. However, communication involves at least two partners, thus outcomes may also vary according to each interaction partners' abilities. We therefore investigated the degree to which the interplay between individual and classmates' communication skills predicts changes in challenging behaviour among students with ID.

METHODS

This study used a longitudinal design with two measurement points across one school year. Challenging behaviour and communication skills were measured by teacher reports in 1125 students with ID attending special needs schools. Applying a multilevel approach, we investigated (1) whether higher individual communication skills at the first measurement were related to a subsequent decrease in challenging behaviour and (2) whether this effect was moderated by classmates' levels of communication skills. In addition, we examined (3) if classroom communication skills were indirectly related to a decrease in challenging behaviour by influencing individual communicative abilities.

RESULTS

Higher individual communication skills at the first measurement were significantly related to a decrease in general challenging behaviour over the school year. This effect was not moderated by classroom-level communication skills. However, classmates' communication skills exerted an indirect influence by enhancing individual communicative abilities. Further analyses suggested classroom contextual effects related to a decrease in several sub-domains of challenging behaviour.

CONCLUSIONS

The study results suggest that both individual communicative competences and those of the classroom context are relevant to understanding challenging behaviour development in ID. Perspectives for counteracting such behaviour in light of the present findings are discussed.

A Neurobehavioral Continuum of Care for Individuals with Intellectual and Developmental Disabilities with Severe Problem Behavior

The Neurobehavioral Programs at Kennedy Krieger Institute constitute a comprehensive continuum of care designed to serve individuals with intellectual and developmental disabilities with co-occurring problem behavior. This continuum includes inpatient, intensive outpatient, outpatient, consultation, and follow-up services. The mission of these programs is to fully integrate patient care, research, training, and advocacy to achieve the best possible outcomes with patients, and to benefit the broader community of individuals with severe behavioral dysfunction. The primary treatment approach utilized across all programs is applied behavior analysis, however the inpatient unit also provides fully integrated interdisciplinary care. Factors driving the development and expansion of these programs are described, as are the processes and systems by which the mission objectives are achieved.

Pediatrics for Disability: A Comprehensive Approach to Children with Syndromic Psychomotor Delay

Intellectual disability is the impairment of cognitive, linguistic, motor and social skills that occurs in the pediatric age and is also described by the term "mental retardation". Intellectual disability occurs in 3-28 % of the general population due to a genetic cause, including chromosome aberrations. Among people with intellectual disabilities, the cause of the disability was identified as a single gene disorder in up to 12 %, multifactorial disorders in up to 4 %, and genetic disorders in up to 8.5 %. Children affected by a malformation syndrome associated with mental retardation or intellectual disability represent a care challenge for the pediatrician. A multidisciplinary team is essential to manage the patient, thereby controlling the complications of the syndrome and promoting the correct psychophysical development. This requires continuous follow-up of these children by the pediatrician, which is essential for both the clinical management of the syndrome and facilitating the social integration of these children.

Etiology and Management of Behavioral Disorder in Adults With Intellectual and Developmental Disabilities

Intellectual disability (ID) encompasses a wide variety of disorders that can severely affect an individual’s cognitive, social, emotional, and physical development, even when identified early in life. Initially, individuals with such disorders had shorter life expectancies. However, medical advances have increased the life expectancy of individuals with ID similar to that of the general population. More attention must be paid to manage diseases affecting the intellectually disabled elderly, such as diabetes, cardiovascular disease, chronic constipation, and behavioral disorders.

A map of assistive technology educative instruments in neurodevelopmental disorders

PURPOSE

The use of assistive technology in mental health has gained an increased interest over the last decades. A growing number of studies have investigated diverse applications of technological interventions for rehabilitation of children with neurodevelopmental disorders. This article presents a map of the technological devises applied as therapeutic instruments.

METHODS

The research question of this review was which technological applications could be referred as an educational instrument for the management of children with autism spectrum disorders (ASDs), intellectual disability and attention deficit disorder. The articles included in this review were collected after a structured literature search in electronic databases using keywords such as "Assistive Technology", "technology devices", "robots", "Autism Disorder", "Intellectual Disabilities" and "Mental Retardation".

RESULTS

Assistive technology with the most up-to-date devices and applications helps children with intellectual disability and ASDs enhance cognitive skills and improve challenging behaviour, social communication and academic performance. Different technological tools are used to foster attention span and improve time management skills in children with attention deficit syndrome.

CONCLUSION

It is important that therapists choose the instrument that will offer the best approach towards the goal that is set. Future research could provide evidence based data, evaluating each specific methodology and tailoring each therapeutic approach specifically to a case.IMPLICATIONS FOR REHABILITATIONTechnology creates environments in which children could practice and learn in a safer, more predictable and pleasant manner.Assistive Technologies provide the opportunity for better acquisition of selfhelp skills and the power of social interaction for individuals with disabilities.By mapping out the wide array of Assistive Technology that is available today, future applications for rehabilitation of children with neurodevelopmental disorders could help extend therapeutic strategies out of the clinical and school settings and into the home, thereby incorporating the family and emphasizing personalization.Future studies could develop a model for the choice and use of each tool, tailoring each therapeutic approach specifically to each case.
