Risk Factors for Self-injurious Behavior in an Inpatient Psychiatric Sample of Children with Autism Spectrum Disorder: A Naturalistic Observation Study

Understanding profound autism: implications for stigma and supports

Introduction

Societal perceptions and lack of understanding of autism spectrum disorder can be stigmatizing for autistic individuals and their families. This may be particularly the case for individuals who meet criteria for profound autism. Despite the considerable service needs of this marginalized group, there is little data on the prevalence of profound autism, nor on the experiences of those with profound autism and their families.

Methods

The current study leveraged a mixed-methods approach to address these gaps. First, the prevalence of profound autism was examined in six samples-three from the United States and three from Western Europe. Second, inductive thematic analysis was used to code interviews from 20 caregivers of profoundly autistic adults.

Results

The prevalence of profound autism varied widely across the six samples-from 11% to 48%. There were also notable differences between samples in prevalence by gender, race, and ethnicity. Two overarching themes were identified via inductive thematic analysis: Community Perceptions of Autism and Family Support Needs and Advocacy Challenges. Though caregivers were not directly asked about stigmatization during interviews, 85% of caregivers reported at least one instance of perceived stigma.

Discussion

Future research should continue to examine the unique needs and stigmatization experiences of profoundly autistic individuals and their families across the life course.

Age- and sex-dependent increase in self-harm among adolescents with mental health problems in East China during COVID-19 related society-wide isolation

Objective

The COVID-19 pandemic has raised concerns about child and adolescent mental health issues, such as self-harm. The impact of society-wide isolation on self-harming behaviors among adolescents in China is unclear. In addition, adolescents of different ages and sexes have varying abilities to cope with environmental changes. However, these differences are rarely considered in self-harm studies. We aimed to characterize the age- and sex-dependent effects of COVID-19-related society-wide isolation on self-harm among adolescents in East China.

Methods

We collected 63,877 medical records of children and adolescents aged 8–18 who had an initial visit to Shanghai Mental Health Center in China between 2017 and 2021 and charted annual self-harm rates for each age and sex. Using interrupted time series analysis, we modeled global and seasonal trends and the effect of COVID-19-related society-wide isolation on self-harm rates.

Results

Females aged 10–17 and males aged 13–16 exhibited significantly increasing trends in self-harm rate (pfdr < 0.05) in the past 5 years. Eleven-year-old females in 2020 showed a self-harm rate (37.30%) that exceeded the peak among all ages in 2019 (age 13, 36.38%). The COVID-19-related society-wide isolation elevated self-harm rates in female patients aged 12 [RR 1.45 (95% CI 1.19–1.77); pfdr = 0.0031] and 13 years [RR 1.33 (95% CI 1.15–1.5); pfdr = 0.0031], while males were less affected. Further, females with emotional disorders dominated the increased self-harm rates.

Conclusion

Society-wide isolation has had a significant impact on early adolescent females in East China, especially for those with emotional disturbances, and has brought forward the peak in adolescent self-harm rates. This study calls for attention to the risk of self-harm in early adolescents.

Characteristics of children with autism and unspecified intellectual developmental disorder (intellectual disability) presenting with severe self-injurious behaviours

Objective: This study aims to delineate the characteristics of severe self-injurious behaviors (SIB) in a cohort of children with autism and unspecified intellectual developmental disorder (UIDD) (intellectual disability) and examine potential risk factors for developing SIB. Methods: A retrospective chart review studied characteristics of severe SIB in 30 children with autism spectrum disorder (ASD) and UIDD referred to a tertiary care center. Characteristics examined include genetic syndromes, brain MRI abnormalities, verbal ability, adaptive functioning, SIB frequency and severity, age of onset, number of psychopharmacological agents, irritability, hyperactivity, stereotypy, psychiatric and physical comorbidities, among others. Descriptive and bivariate analysis were applied to explore potential relationships between factors. Results: Children with severe SIB exhibit this behaviour with high frequency, inflicting moderate to severe injury. Most children in the study sample are non-verbal and have ASD (93.3%; n = 28) with psychiatric (96.7%; n = 29) and physical (90%; n = 27) comorbidities. Overall SIB improvement using the Clinical Global Impression, Improvement Score (CGI-I) was 3.0 (minimally improved). A minority were much or very much improved following appropriate intervention. Conclusions: The severity of SIB is much higher in this sample than previously noted in the literature. Severe SIB is associated with ADHD, early onset mood disorders, tics, avoidant restrictive food intake disorder and Obsessive-Compulsive Disorder.

Preliminary Development and Testing of the Risk Assessment Checklist for Self-Injury in Autism-Medical (RACSA-M)

Self-injurious behavior (SIB) is a major treatment focus for clinicians treating children with autism spectrum disorder (ASD). A review of the literature identified medical conditions that may be risk factors for an individual engaging in SIB. This study involved the creation and preliminary validation of a standardized assessment checklist: Risk Assessment Checklist for Self-Injury in Autism-Medical (RASCA-M) for the physical, behavioral, and diagnostic evaluation of non-verbal children with autism and SIB living in a residential setting. Preliminary content validity, criterion-related validity, and interobserver agreement were established. The RACSA-M is a promising instrument to assess underlying medical issues in non-verbal children with ASD and SIB.

Relationships Between Emotion Regulation, Social Communication and Repetitive Behaviors in Autism Spectrum Disorder

The relationship between emotion regulation, social interaction and different types of restricted and repetitive behaviors is poorly understood. In the present study, structural equation modeling based on information about 239 individuals with autism was used to examine whether emotion regulation and social communication were associated with self-injury and stereotyped behaviors. Results showed that poor emotion regulation had a unique association with self-injury while difficulties with social communication was uniquely associated with stereotyped behaviors. Emotion regulation and social communication were strongly associated and self-injury and stereotyped behaviors moderately associated. This implies that these types of behaviors are often expressions of broader negative emotional states in autism. Treatments that help improve coping and social communication strategies may benefit individuals with autism.

Health-related risky behaviors in Chinese adolescents with autism: a cross-sectional study

BACKGROUND

Health-related risky behaviors (HRB) generally refer to behaviors that have a negative influence on health and quality of life. HRB in adolescents with autism have not been well understood so far. We aim to explore health-related risky behaviors and their risk factors with autistic adolescents.

METHODS

In this study, 150 adolescents with autism and 150 neurotypical adolescents were enrolled. Participants in both groups completed the Adolescent Health-Related Risky Behavior Inventory (AHRBI). Autism Spectrum Screening Questionnaire (ASSQ), Wechsler Intelligence Scale, Theory of Mind (ToM) Test, Zung Self-rating Anxiety Scale (SAS), Zung Self-rating Depression Scale (SDS), and Self-Esteem Scale (SES) were also assessed in the autism group to explore risk factors.

RESULTS

The results showed that the total score of AHRBI and scores of "aggression and violence (AV)", "suicide or self-injury (SS)", "health-compromising behavior (HCB)", and "unprotected sex (US)" subscales in the autism group were significantly higher than those in the control group (Z value = - 4.58 ~ - 2.26, all P < 0.05). Anxiety, depression, low self-esteem, low IQ score, low ToM test score, increasing age, and communication disorder were found as risk factors for health-related risky behaviors in autistic adolescents.

CONCLUSIONS

Adolescents with autism have more health-related risky behaviors than neurotypical adolescents. We should pay attention to the emotional state, self-esteem, cognitive function, and verbal communication levels of autistic adolescent with health-related risky behaviors.

Intentional Self Harm in Children with Autism

The study examined the demographic, socioeconomic, and clinical correlates of self injurious behaviors (SIBs) in a large clinical sample of children with autism spectrum disorder (ASD). A case record review of 1252 ASD children for whom complete information on socioeconomic background variables and presence/absence of SIBs was available were included. The overall prevalence of SIBs was 22.1% and the most prevalent SIBs were head banging (47%), followed by self hitting (27.8%). Several factors including age at diagnosis (t = 2.09, P = 0.037), education of mother (χ² = 14.48, P = 0.0001), presence of co-morbid medical condition (χ² = 4.22, P = 0.040), intellectual disability (χ² = 23.17, P = 0.0001), sensory processing abnormalities (χ² = 13.01, P = 0.0001), and severity of autism (χ² = 51.13, P = 0.0001) were found to be significantly associated with presence of SIBs. Logistic regression analysis revealed that severity of autism was the only significant predictor of SIBs. Intentional self harm is related with significant morbidity and needs early intervention.

Prevalence and clinical correlates of self-harm and suicidality during admission of children in a mental health inpatient unit

Background

Self-harm and suicidality are common presentations in children and adolescents requiring a mental health inpatient admission. Although there are several studies on adolescents, there is relatively limited research into childhood self-harm and suicidality during such admissions.

Methods

A retrospective electronic file review was conducted on all children discharged from a national mental health inpatient children’s unit over a 6-year period. Several independent variables were compared between self-harm/suicidal and non-self-harm/non-suicidal children. Separate analyses investigated changes in self-harm/suicidality, functional outcomes, and risk assessment ratings between admission and discharge.

Results

A total of 105 children were included in this study. During admission, 65.7% of them reported self-harm thoughts, 61% engaged in self-harm, 50.5% expressed suicidal thoughts, and 14.3% engaged in suicidal behavior. Thoughts and acts of self-harm were associated with previous self-harm, longer admissions, and Attention Deficit Hyperactivity Disorder. Suicidality overlapped with self-harm and was strongly predicted by previous self-harm. The prevalence of self-harm and suicidal thoughts and acts significantly decreased during admission. Children in the non-self-harm group had marginally better functional outcomes upon discharge compared to those in the self-harm group. Children and parents/caregivers were similarly satisfied with treatment, irrespective of children’s self-harm/suicidality.

Conclusions

Self-harm and suicidality were widespread among children admitted to hospital. Better understanding of the mechanisms and factors related to self-harm and suicidality in this age group could help mitigate associated risks and improve existing safety strategies.

The Prevalence of Self-injurious Behaviour in Autism: A Meta-analytic Study

Self-injurious behaviour is purportedly common in autism, but prevalence rates have not yet been synthesised meta-analytically. In the present study, data from 14,379 participants in thirty-seven papers were analysed to generate a pooled prevalence estimate of self-injury in autism of 42% (confidence intervals 0.38-0.47). Hand-hitting topography was the most common form of self-injury (23%), self-cutting topography the least common (3%). Sub-group analyses revealed no association between study quality, participant intellectual disability or age and overall prevalence rate of self-injury. However, females obtained higher prevalence rates than males (p = .013) and hair pulling and self-scratching were associated with intellectual disability (p = .008 and p = .002, respectively). The results confirm very high rates of self-injury in autism and highlight within group risk-markers.

The multiple faces of catatonia in autism spectrum disorders: descriptive clinical experience of 22 patients over 12 years

A retrospective review was conducted from the inpatient and outpatient records of twenty-two autistic youth presenting to a neurobehavioral service over a twelve-year period for combined psychiatric and behavioral pathology who also met DSM5 criteria for catatonia. Six autistic girls and 16 autistic boys ranging from ages eight to 26 years old were identified, and their variegated symptoms evaluated. Stereotypy, posturing, negativism, mutism and stupor were the most common catatonic symptoms, each present in more than half of the study patients. One patient had abnormal vital signs indicative of malignant catatonia. Twenty patients had concomitant repetitive self-injurious behaviors that had led to significant tissue injury and were refractory to psychotropic and behavioral interventions. The sample was weighted towards patients with severe self-injurious behavior, which often was the reason for admission. The many "faces" of catatonia in autism spectrum disorders are seen in this sample, and the novel recognition of repetitive self-injury as an under-recognized motor symptom of catatonia is highlighted. The preliminary findings in this study open many important future vistas for ongoing research regarding catatonia in ASDs.

The Severe End of the Spectrum: Insights and Opportunities from the Autism Inpatient Collection (AIC)

Research on individuals severely affected by autism, including those who are minimally verbal, have intellectual disability or challenging behaviors, has become less common. The Autism Inpatient Collection (AIC) was initiated so data on this group is available to the research community. Ten studies utilizing phenotypic data from the first 350 AIC participants are presented. Greater autism severity, sleep disturbance, and psychiatric disorders are risks for hospitalization; fluently verbal youth experience more depression and oppositional symptoms; lower adaptive/coping skills are associated with increased problem behaviors; lower IQ is a risk for SIB; post-traumatic and suicidal symptoms are common; and challenging behaviors improve with specialized inpatient treatment. A new measure of emotion regulation and prescribing practices are described and future research discussed.
