Self-injurious, aggressive and destructive behaviour in children with severe intellectual disability: Prevalence, service need and service receipt in the UK

A Meta-Analysis of Treatment for Self-Injurious Behavior in Children and Adolescents With Intellectual and Developmental Disabilities

Self-injurious behavior (SIB) among children and youth with developmental disabilities has not diminished in prevalence despite the availability of effective interventions, and the impact on quality of life for people and their families is devastating. The current meta-analysis reviews SIB intervention research between 2011 and 2021 using single-case experimental designs with children and youth up to 21 years old and provides a quantitative synthesis of data from high-quality studies including moderator analyses to determine effects of participant and study characteristics on intervention outcomes. Encouraging findings include a high level of effectiveness across studies in the decrease of SIB (Tau-U = -0.90) and increase of positive behavior (Tau-U = 0.73), as well as an increase in studies (relative to prior reviews) reporting intervention fidelity, generalization, maintenance, and social validity. However, our findings shed limited light on potential moderating variables in the development of interventions for children and youth who exhibit SIB. Of the potential moderators of intervention effects, only implementer (researcher/therapist vs. parent/caregiver) and setting (clinic vs. home) were significantly associated with improved outcomes. We discuss the need for more robust involvement of natural communities of implementers in SIB intervention research to better equip them to effectively and sustainably meet the needs of people they care for. We also discuss the importance of creating systems enabling broad access for children with SIB to effective interventions in service of reducing burden for people, families, and society over time.

Headache in Individuals with Neurodevelopmental Disorders

PURPOSE OF REVIEW

Migraine is a common condition affecting an estimated billion people across the world. The incidence in individuals with neurodevelopmental disorders or intellectual disabilities like those seen in severe autism spectrum disorder (ASD) is unknown. This is likely due to the limited capacity to communicate the specifics of pain. The expression of pain with maladaptive behaviors, such as self-injurious behavior (SIB), has been described and can alert the clinician to the presence of untreated pain. This review article serves to educate the reader about clinical and treatment considerations when managing headaches in individuals with severe or non-verbal neurodevelopmental disorders given their communication challenges. It will include some clinical experiences and the gaps in our current knowledge.

RECENT FINDINGS

A comprehensive literature review was conducted using scientific databases, including PubMed, Medline, and Google Scholar. Only 1 article addressed the consideration for headaches in this population. The search was conducted using a combination of the following keywords: headache, intellectual disabilities, autism, pain, and behavior. Headache pain is likely underestimated and represents a disservice to this population of people. The consideration for headache pain should be explored when maladaptive behaviors are otherwise unexplainable. Further studies are needed in the area.

A Qualitative Analysis of Family Caregiver Experiences Accessing Treatment for Self-Injurious Behavior in Individuals with Intellectual and Developmental Disabilities

Introduction

There is evidence of a gap between individuals with intellectual and developmental disabilities (IDD) who need treatment for self-injurious behavior (SIB) and those who receive treatment. The purpose of this study (n=15) was to begin to understand the treatment gap from the perspective of family caregivers.

Methods

In semi-structured virtual interviews, family caregivers discussed their experiences of working with providers to treat their child's or sibling's self-injury. Through a systematic process of quasi-inductive thematic analysis, researchers transcribed and analyzed the interviews and developed a working model of treatment pathways.

Results

Caregivers described many barriers to treatment access. Themes include Caregiver Driven, Importance of the Provider-Caregiver Relationship, Beliefs and Perceptions about SIB, Practical Constraints, Knowledge Gaps, and Wait Until Crisis.

Conclusion

The findings highlight the power of providers to support families coping with SIB in IDD. Specific ways providers can better facilitate treatment access are suggested. Future research directions should include provider interviews and focus groups and, ultimately, the development of interventions that consider access pathways as a key feature of any effective treatment plan.

Assessment of Challenging Behavior Exhibited by People with Intellectual and Developmental Disabilities: A Systematic Review

The assessment of challenging behavior exhibited by people with intellectual and developmental disabilities is essential for the planning of prevention and intervention programs. This review aimed to identify and analyze the standardized instruments that exclusively focus on the assessment of challenging behavior. We identified and organized 141 articles into four categories: original instrument studies, validation studies, relational studies, and intervention studies. The results identified 24 instruments that generally show high-quality psychometric properties and other utilities beyond the observation of the presence of challenging behavior and diagnostic categorization. Age, level of adaptive behavior, disability, presence of autism spectrum disorder, and medication are some of the variables that were found to be possibly related to the occurrence of challenging behavior. Additionally, the results suggest that interventions focused on supporting positive behavior or providing training on behavior to professionals and caregivers significantly reduced the occurrence of these behaviors. Instruments that help us to understand and measure the challenging behavior exhibited by people with intellectual and developmental disabilities are essential for the design of effective evaluation and intervention protocols.

Emergency Department Visits for Non-suicidal Self-harm, Suicidal Ideation, and Suicide Attempts in Children and Adolescents

Self-harm presentations to emergency departments (ED) have become a growing concern, yet little is known about self-harm visits in pediatric EDs. This study aimed to investigate the clinical and demographic characteristics of patients who presented to the pediatric ED between 2012 and 2017 with non-suicidal self-harm (NSSH, n = 63, 60.3% female, M = 14.25 years), suicidal ideation (SI, n = 75, 57.3% female, M = 14.83 years), and suicide attempts (SA, n = 461, 82.9% female, M = 15.41 years). Also, predictors of SA were investigated. Of the patients, 79.4% had at least a psychiatric disorder. Depression was the most common diagnosis in the SI and SA groups, and autism spectrum disorder and intellectual disability were the leading diagnoses in the NSSH group. Self-poisoning was the most common method, and older age, female sex, having relational problems, and prior or current psychiatric admissions were the most important predictive factors of SA. NSSH, SI, and SA exhibit different features in early life. EDs provide an important opportunity for initiating developmentally appropriate interventions to reduce future risks.

Challenging behaviors among students with severe developmental disabilities in Saudi Arabia: Impact of socio-demographic differences

This study aimed to explore the prevalence of challenging behaviors (CBs) associated with students with severe developmental disabilities (SDDs) as rated by their teachers. The study also attempted to examine whether the occurrence and intensity of CBs might depend on certain socio-demographic variables. Data was collected using a questionnaire to rate the prevalence of CBs in 687 students with SDDs. Results indicate that social problems, stereotypical behaviors, and disobedient behaviors were estimated to be the most prevalent of CBs among such students. Positive correlations were confirmed between the type of disability, gender, age, school grade, educational placement, and the prevalence of CBs among students with SDDs. Implications for educational practice and recommendations for future research are discussed.

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.

The evolution of self-injurious behaviors in people with intellectual disability and epilepsy: A follow-up study

PURPOSE

Longitudinal studies of the evolution of Self-Injurious Behaviors (SIBs) in people with Intellectual Disability (ID) and epilepsy are not common. This study aimed to analyze the evolution (in terms of remission and persistence) and changes in the type, localization, frequency, and intensity of SIBs.

METHODS

SIBs were assessed in a sample of 52 people with ID and epilepsy, and re-evaluated after a seven-year interval, using the "Scale for the Assessment of Self-Injurious Behaviors". The scale was administered to caregivers (parents or health professionals) through a semi-structured interview conducted by a specifically trained psychologist.

RESULTS

The most frequent types of SIBs identified were: self-biting, self-hitting with objects, self-hitting with hand, object-finger in cavities. The main localizations of SIBs were: hands, mouth, head and cheeks. SIBs were found to be maintained after seven years, for type, localization, frequency, and intensity, in 90.4% of the sample. SIB types were stable over time, as were the affected areas. Global SIB frequency and intensity scores were found to be unchanged. Finally, a positive correlation was found between the frequency of SIBs and levels of intellectual disability. SIBs (frequency and intensity) and seizure frequency showed no correlation.

CONCLUSION

Given the negative impact of SIBs on the adaptation and quality of life of people with ID and epilepsy, we believe that further studies on biological, psychological and environmental aspects are needed in order to identify any potential factors that might explain the persistence of SIBs and to find effective interventions to reduce them.

Persistence and predictors of self-injurious behaviour in autism: a ten-year prospective cohort study

Background

Self-injurious behaviours, such as head banging, hair pulling, skin picking and scratching, are common in individuals with autism. Despite high prevalence rates, there is a paucity of longitudinal research to refine models of risk and mechanism and inform service planning. In this longitudinal study, we investigated self-injury in a cohort of individuals with autism over 10 years to identify behavioural and demographic characteristics associated with persistent self-injury.

Methods

Carers of 67 individuals with autism completed questionnaires relating to the presence of self-injury and relevant risk markers at T1 (mean [SD] age in years 13.4 [7.7]) and T3 (mean [SD] age in years 23.9 [7.7]) 10 years later. Forty-six of these also took part at T2 (3 years after initial participation). Analysis assessed demographic and behavioural risk markers for self-injury, as well as the predictive value of items assessed at T1and T2.

Results

Self-injury was persistent in 44% of individuals over the 10-year period, with behavioural characteristics of impulsivity (p < .001) and overactivity (p = .002), identified as risk markers for persistence. A predictive model of self-injury was derived from LASSO analysis, with baseline impulsivity, interest and pleasure, stereotyped behaviour, social communication and adaptive functioning predicting self-injury over 10 years.

Conclusions

In this unique longitudinal investigation into the persistence of self-injury in a non-clinical sample of individuals with autism over a 10 year period, we have identified a novel, robust and stable profile of behavioural characteristics associated with persistent self-injury. Findings support an early intervention strategy targeted towards individuals identified to be at a higher risk of developing self-injurious behaviour.

Predictors of Inpatient Psychiatric Hospitalization for Children and Adolescents with Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is associated with significant healthcare expenditures and a greater utilization of psychiatric health services. High utilization may not be evenly distributed across individuals with ASD. The objective of this study was to identify individual and family characteristics that increase the risk of psychiatric hospitalization. Naturalistic study of two age- and gender-matched ASD cohorts, inpatients enrolled in the Autism Inpatient Collection (AIC) and outpatients enrolled in the Rhode Island Consortium of Autism Research and Treatment (RI-CART), revealed a number of factors associated with hospitalization. Multiple logistic regression analyses revealed that adaptive functioning, ASD symptom severity, primary caregiver's marital status, the presence of mood disorders, and the presence of sleep problems independently increased the risk of psychiatric hospitalization.

Brief Report: Self-Injurious Behaviors in Preschool Children with Autism Spectrum Disorder Compared to Other Developmental Delays and Disorders

We compared the prevalence of self-injurious behaviors (SIB) in preschoolers aged 30-68 months with autism spectrum disorder (ASD) (n = 691) versus other developmental delays and disorders (DD) (n = 977) accounting for sociodemographic, cognitive, and medical factors. SIB prevalence was higher in ASD versus all DD [adjusted odds-ratio (aOR) 2.13 (95% confidence interval (95% CI) 1.53, 2.97)]. In subgroup analyses, SIB prevalence was higher in ASD versus DD without ASD symptoms [aOR 4.42 (95% CI 2.66, 7.33)], but was similar between ASD and DD with ASD symptoms [aOR 1.09 (95% CI 0.68, 1.77)]. We confirmed higher prevalence of SIB in ASD versus DD, independent of confounders. In children with DD, SIB prevalence increased with more ASD symptoms. These findings are informative to clinicians, researchers, and policymakers.

Self-Injury in Autism Spectrum Disorder and Intellectual Disability: Exploring the Role of Reactivity to Pain and Sensory Input

This paper provides information about the prevalence and topography of self-injurious behavior in children and adults with autism spectrum disorder and intellectual disability. Dominant models regarding the etiology of self-injury in this population are reviewed, with a focus on the role of reactivity to pain and sensory input. Neuroimaging studies are presented and suggestions are offered for future research.

Self-injurious behaviour in people with intellectual disability and autism spectrum disorder

PURPOSE OF REVIEW

This review summarises the recent trends in research in the field of self-injurious behaviour in people with intellectual disability and autism spectrum disorder.

RECENT FINDINGS

New data on incidence, persistence and severity add to studies of prevalence to indicate the large scale of the clinical need. A number of person characteristics have been repeatedly identified in prevalence and cohort studies that: can be considered as risk markers (e.g. stereotyped behaviour, autism spectrum disorder) and indicate possible causal mechanisms (e.g. sleep disorder, anxiety). Studies have started to integrate traditional operant learning paradigms with known person characteristics and reviews and meta-analyses of applied behaviour analytic procedures can now inform practice.

SUMMARY

Despite these positive developments interventions and appropriate support falls far short of the required need. Expansions in applied research are warranted to develop and evaluate innovative service delivery models that can translate knowledge of risk markers and operant learning paradigms into widespread, low cost routine clinical practice. Alongside this, further pure research is needed to elucidate the direction of causality of implicated risk factors, in order to understand and intervene more effectively in self-injury.
