Systematic Review of Suicide in Autism Spectrum Disorder: Current Trends and Implications

Examination of the Potential Moderating Role of Psychological Wellbeing in the Relationship Between Depression and Thoughts of Self-Harm in Autistic Adolescents and Adults: A Two-Year Longitudinal Study

PURPOSE

Autistic people have a significantly increased risk of death by suicide relative to the general population. In non-autistic samples, psychological wellbeing has been shown to moderate the relationship between depression and suicidal thoughts and behavior. Thoughts of self-harm may provide a useful indicator of suicidal risk. In this longitudinal study we examined (a) the potential role for psychological wellbeing to moderate the relationship between depressive symptoms and thoughts of self-harm and (b) the contribution of autistic traits to thoughts of self-harm.

METHODS

Participants were 209 autistic adolescents and adults aged 15 to 80 years (Mage = 34.20, SD = 15.38 years).

RESULTS

At both baseline and 2-year follow-up, 35% of participants reported recent thoughts of self-harm. Wellbeing was associated with autistic traits (r = - .350 to - 0.404) and depression (r = - .480 to - 0.759). Thoughts of self-harm were positively associated with autistic traits and depression (r = .242 to 0.659), and negatively associated with wellbeing (r = - .287 to - 0.609). Controlling for baseline thoughts of self-harm, depression (β = 0.254, p = .001) and autistic traits (β = 0.162, p = .007) significantly predicted thoughts of self-harm at 2-year follow-up.

CONCLUSION

Despite a lack of support for the hypothesis that wellbeing would moderate the relationship between depression and thoughts of self-harm, correlational data demonstrated significant associations between wellbeing and both depression and thoughts of self-harm. Future research considering psychological wellbeing as a potential protective factor for self-harm in autistic people is warranted.

Predictors of Depressive Symptoms in Autistic Youth-A Longitudinal Study From the Province of Ontario Neurodevelopmental Disorders (POND) Network: Prédicteurs des symptômes dépressifs chez les jeunes autistes-une étude longitudinale du Réseau des troubles neurodéveloppementaux de la province de l'Ontario (réseau POND)

OBJECTIVE

The objective of this study was to identify longitudinal predictors of depressive symptoms in autistic children and youth.

METHODS

Participants were youth with a diagnosis of autism who were part of the Province of Ontario Neurodevelopmental Disorders Network longitudinal substudy. Depressive symptoms were assessed using the child behaviour checklist (CBCL) affective problems subscale. Univariate and multivariable logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between clinical and demographic characteristics at baseline (T1) and clinically elevated depressive symptoms (CEDS) approximately 4 years later (T2).

RESULTS

The mean age of participants (n = 75) at T1 was 9.8 years (SD = 2.7) and at T2 was 14.1 years (SD = 2.8). A total of 37% and 35% of participants had CEDS at T1 and T2, respectively. Additionally, 24% of participants had CEDS at both T1 and T2. T1 characteristics associated with T2 CEDS were: loneliness (OR = 3.0, 95% CI, 1.1 to 8.8), self-harm (OR = 4.0, 95% CI, 1.1 to 16.9), suicidal ideation (OR = 3.9, 95% CI, 1.0 to 16.5), more social and adaptive skills (OR = 0.3, 95% CI, 0.1 to 0.9), elevated restricted and repetitive behaviours (OR = 3.8, 95% CI, 1.3 to 11.6), psychotropic medication use (OR = 3.0, 95% CI, 1.1 to 8.4), attention-deficient/hyperactivity disorder (OR = 2.8, 95% CI, 1.1 to 7.8), and T1 CEDS (OR = 8.8, 95% CI, 3.1 to 27.0) (uncorrected for multiple comparisons). Associations persisted after adjusting for age and intelligence quotient (IQ) differences. Age, sex, IQ, teasing/bullying on the CBCL, family psychiatric history and family income were not associated with T2 CEDS.

CONCLUSION

Our results highlight both high prevalence and high potential for the persistence of depressive symptoms in autism and emphasize the importance of early support to address loneliness and social participation.

Measuring and validating autistic burnout

Researchers have begun to explore the characteristics and risk factors for autistic burnout, but assessment tools are lacking. Our study comprehensively examined and compared the psychometric properties of the unpublished 27-item AASPIRE Autistic Burnout Measure (ABM), and personal and work scales of the Copenhagen Burnout Inventory (CBI) to evaluate their efficacy as screening measures for autistic burnout, with a group of 238 autistic adults. Exploratory factor analyses (EFA) revealed a 4-factor structure for the ABM and a 2-factor structure for the CBI personal scale (CBI-P). Factorial validity and dimensionality were examined with four exploratory models which indicated a unidimensional structure for the ABM with an overarching 'Autistic Burnout' construct, and multidimensional CBI-P structure comprising two subscales and overarching 'Personal Burnout' construct. Other reliability and validity indicators included Spearman correlations, analysis of variance, receiver operating characteristics, sensitivity, specificity, and intra-class correlations (ICC). The ABM and CBI-P were strongly correlated with depression, anxiety, stress, and fatigue. Unexpectedly, correlations between the burnout measures and camouflaging, and wellbeing measures were moderate. Potential overlap between burnout and depression and fatigue was examined through EFA, which supported convergent validity of the ABM and depression measure, while correlations and ICC analyses revealed mixed results. We concluded that the ABM and the CBI-P Emotional Exhaustion subscale were valid preliminary screening tools for autistic burnout. Testing with larger and more diverse autistic samples is required to further examine the psychometric properties of the ABM, and to understand the relationships between autistic burnout and depression, and masking.

Autism Spectrum Disorder and Suicide: A Case Report

Autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) significantly impact mental health, increasing the risk of severe behaviors, including suicidality. This case report examines a 13-year-old boy with ASD and ADHD who presented to the emergency department with homicidal and suicidal ideations. Despite being prescribed risperidone and carbamazepine, his noncompliance with medication and therapy, combined with significant social stressors like physical abuse by his stepfather and his mother's mental health issues, exacerbated his condition. His aggressive actions toward siblings and self-harm attempts highlight the severe behavioral manifestations of these conditions. The case underscores the necessity for comprehensive and consistent intervention strategies, robust support systems, and regular follow-ups to manage ASD and ADHD effectively and mitigate the risk of severe outcomes.

Concordance Between the Ask Suicide Screening Questions (ASQ) and Self-Injurious Thoughts and Behaviors Interview-Self Report (SITBI-SR) Among Autistic and Non-Autistic Adults

OBJECTIVE

This study sought to examine concordance between two commonly used measures of suicidal thoughts and behaviors: the Ask Suicide-Screening Questions (ASQ) and the Self-Injurious Thoughts and Behaviors Interview-Self Report (SITBI-SR). Agreement was operationalized as the presence past month suicidal ideation and lifetime suicide attempts. To explore the utilization of these tools among neurodiverse samples, we also examined the concordance across autistic and non-autistic adults.

METHODS

The sample consisted of 200 individuals recruited online. Half of the sample self-reported a diagnosis of autism. A series of Cohen's kappas and confidence intervals were computed to assess agreement between the ASQ and SITBI-SR. Cohen's kappa was computed separately for each set of comparisons for the autistic and non-autistic samples.

RESULTS

Past month suicidal ideation had a kappa of 0.61 (95%CI = 0.48-0.73). The kappa for lifetime suicide attempts was 0.86 (95%CI = 0.78-0.94). There were no significant differences in agreement between the two measures for autistic versus non-autistic individuals.

CONCLUSIONS

Current findings suggest that the ASQ and SITBI-SR have high concordance with one another. Given that the ASQ and the SITBI-SR are both validated in the general population and that concordance was high and not significantly different based on autism status, the current study provides preliminary evidence that the ASQ and the SITBI-SR function similarly for autistic individuals.HIGHLIGHTSPeople do not always respond consistently to different STB assessment methods.Findings suggest that the ASQ and SITBI-SR have high concordance with one another.Evidence provided that these measures function similarly for autistic individuals.

Subjective wellbeing of autistic adolescents and young adults: A cross sectional study

Subjective wellbeing (SWB) represents an individual's perception of wellness that is supported by homeostatic mechanisms. These mechanisms are proposed to be maintained by low negative affect and high positive affect, although less is known about these mechanisms and SWB in autism. The current cross-sectional study aimed to compare patterns of positive affect, negative affect (Positive Affect and Negative Affect Scale), and SWB (Personal Wellbeing Index-School Children) between autistic (n = 53) and non-autistic (n = 49) individuals aged 10-22 years (Mage = 13.97, SD = 3.13). Between-group t-tests revealed that compared with same-age peers, autistic participants scored lower SWB overall (p < 0.001). In both groups average SWB scores fell into the higher range, however, autistic participants were three-times more likely to fall below this range when compared to non-autistic participants. Negative affect had a higher intercept in the autistic sample, but no difference in slopes were observed. A hierarchical multiple regression revealed that diagnosis, positive affect, and negative affect significantly predicted SWB in our sample. Between-group t-tests found no significant difference in positive affect or negative affect across age between the autistic and non-autistic samples. In autistic participants, positive affect increased across age as SWB decreased, whilst negative affect remained stable, a pattern inconsistent with homeostatic SWB. The current study is overall consistent with the homeostatic explanation for SWB within autism; however, we identified potential differences between autistic and non-autistic participants in the contribution of positive affect and negative affect to homeostatic protect mood across development.

The effectiveness and safety of dialectical behavior therapy for suicidal ideation and behavior in autistic adults: a pragmatic randomized controlled trial

BACKGROUNDS

Many autistic people in mental health are suicidal. This study evaluated the effectiveness of dialectical behavior therapy (DBT) v. treatment as usual (TAU) in reducing suicidal ideation and suicide attempts.

METHODS

At six Dutch mental health centers, 123 outpatients (18-65 years) with DSM-5 diagnosed autism spectrum disorder (ASD) and suicidal behavior were randomly assigned to the DBT intervention group (n = 63) or TAU control group (n = 60). Assessments were conducted at baseline, post-treatment at 6 months and 12-month follow-up. The primary outcomes were severity of suicidal ideation and frequency of suicide attempts. The severity of depression and social anxiety were secondary outcomes.

RESULTS

At end-of-treatment, DBT significantly reduced both suicidal ideation (z = -2.24; p = 0.025; b = -4.41; s.e. = 197.0) and suicide attempts (z = -3.15; p = 0.002; IRR = 0.046; s.e. = 0.045) compared to TAU, but lost statistical significance at the 12-month follow-up. Depression severity significantly decreased with DBT (z = -1.99; p = 0.046: b = -2.74; s.e. = 1.37) remaining so at 12 months (z = -2.46; p = 0.014; b = -3.37; s.e. = 1.37). No effects were observed on social anxiety. Severe adverse events included two suicides in the TAU condition.

CONCLUSIONS

DBT is an acceptable, safe, and short-term effective intervention to reduce suicidal ideation and suicide attempts in autistic adults with suicidal behavior.

Self-compassion improves emotion regulation and mental health outcomes: A pilot study of an online self-compassion program for autistic adults

LAY ABSTRACT

Self-compassion is when we are aware of our feelings and thoughts, are friendly toward ourselves, and realize everyone feels pain and makes mistakes. Self-compassion is associated with having better mental health and well-being in autistic and non-autistic people. But we do not know if autistic people's self-compassion can be improved through psychoeducation and self-compassion practices. We co-produced an online self-guided self-compassion program based on evidence-based self-compassion practices for autistic adults called the Self-compassion Program for Autistic Adults. This program included live-experiences videos of autistic adults reflecting on their self-compassion and self-critical experiences. This study piloted the program with 39 autistic adults. We wanted to see if these autistic adults' self-compassion, emotion regulation, mental health, and psychological well-being improved after completing this program. We found that the autistic participants' self-compassion, emotion regulation, mental health, and psychological well-being improved significantly after completing the program over 5 weeks. We also found that just over half of the participants reported experiencing negative reactions associated with self-compassion practices. We suggested some clinical implications, including a recommendation for emotion regulation interventions to incorporate self-compassion to help promote access to the affiliative system. In addition, autistic adults who are psychologically vulnerable may need to work with mental health professionals while developing self-compassion to help manage the possible negative reactions associated with some self-compassion practices.

Autistic traits in adolescents in psychiatric inpatient care: Clinical and demographic characteristics and correlates

Background

Rates of psychiatric hospitalization among adolescents in the United States are rising, with many adolescents presenting to these settings with diverse clinical presentations, including autistic traits. To our knowledge, there has been little research identifying clinical characteristics of adolescents with autistic traits admitted to psychiatric inpatient units, which may be leveraged to improve assessment and treatment practices.

Method

In the current study, we examined clinical and demographic characteristics of 195 adolescents admitted to an adolescent psychiatric inpatient unit. Specifically, we investigated the prevalence of adolescents endorsing elevated autistic traits and tested associations between autistic traits, psychiatric symptoms (anxiety, depression, suicidal thoughts), and key demographic variables (age, sex, gender, sexual orientation).

Results

Results show that over half of the adolescents admitted to the psychiatric inpatient unit reported elevated autistic traits on a short screening questionnaire. Higher autistic traits were significantly associated with more severe depressive symptoms, though to a small degree. Autistic traits were not associated with anxiety symptoms, suicidal thoughts, nor social disconnectedness, and did not differ by sex, gender identity, nor sexual orientation.

Conclusions

Findings highlight the challenge of diagnostic overshadowing among adolescents in crisis and the need for more rigorous measures designed for an inpatient setting to improve risk stratification, clinical assessments, intervention approaches, and discharge planning.

A US national update of health condition prevalence among privately-insured autistic adults

Aim: Previous research using state or regional samples has shown that autistic adults have a higher prevalence of health conditions in comparison to the general population. Methods: To build upon this important previous research, we conducted a cross-sectional retrospective study of 2019-2020 healthcare claims to determine the prevalence of conditions in a US national sample of privately insured autistic adults (n = 30,258) and an age- and sex-matched population comparison (n = 60,516) group of adults without autism diagnoses. Results: Like previous studies, we found that autistic adults had significantly greater odds of most mental and physical health conditions. However, our prevalence estimates differed from previous studies for several mental and physical health conditions. For example, our sample of autistic adults had higher prevalence of anxiety disorders (55%) and attention deficit hyperactivity disorders (34%), but lower prevalence of asthma (9%) and sleep disorders (3%) than previous studies. Discussion & conclusion: Our use of a large US national sample, more recent healthcare claims data, and different methods for identifying health conditions may have contributed to these differences. Our findings alert healthcare providers and policymakers to the health conditions most common among the growing population of autistic adults. We hope these findings lead to improved screening and management of these conditions, inform initiatives to improve access to healthcare, and guide future funding.

Use of ECT in Autism Spectrum Disorder and/or Intellectual Disability: A Single Site Retrospective Analysis

Autism spectrum disorder (ASD) and intellectual disability (ID) are heterogenous and prevalent conditions which may occur in isolation or as a co-morbidity. Psychiatric co-morbidity is common with limited treatment options. Preliminary research into electroconvulsive therapy (ECT) for these conditions has been encouraging. Thus, further research in this patient population is warranted. We conducted a 10-year retrospective review of the electronic medical record and identified intellectually capable individuals with ASD (IC-ASD), and those with ASD+ID or ID who received at least three ECT treatments. 32 patients were identified of which 30 (94%) experienced positive clinical response, defined as a clinical global impression-improvement (CGI-I) score of 3 or less. The average retrospective CGI-I score across all groups was 1.97, and results of a t-test performed on CGI-I scores indicated improvement across all groups [t = - 16.54, df = 31, p < 0.001, 95% CI = (1.72, 2.22)]. No significant adverse events were identified based on clinical documentation. Our findings further support previous ECT research in this patient population.

Suicide risk in transition-aged autistic youth: The link among executive function, depression, and autistic traits

LAY ABSTRACT

Autistic people are more likely to consider suicide than non-autistic people, with transition-aged youth (ages 16-21 years) at potentially the highest risk. Research has also shown that difficulties with executive functioning (e.g., difficulties with organization, sequencing, and decision-making) may heighten suicide risk among non-autistic people, but it is not clear whether this is also true for autistic people. This study explored this question by asking 183 transition-aged autistic youth about their experience with suicidal behavior and examining the relationship between their responses and additional measures of depression, autistic traits, and executive function skills. About one-third of autistic transition-aged youth (33.3%) said that they had experienced thoughts of hurting themselves with the intent to end their lives (i.e., suicidal ideation). Both depression and executive function challenges predicted suicide risk (i.e., participants who experienced depression were more likely to have had suicidal thoughts than those who had not, and participants who had more difficulty with executive function skills were more likely to have had suicidal thoughts than those who had less difficulty). These findings suggest that executive functioning, a common area of difficulty among autistic people, is an important indicator of suicide risk in this population.

Characterising the behaviours in most severe and least severe emotional outbursts in young people

Emotional outbursts are displays of intense, challenging behaviour and are prevalent in individuals with neurodevelopmental disorders. Outbursts present a danger to individuals and their carers and are cited as reasons for referral to mental health services. However, it is currently unclear how the characteristics of outbursts may determine their severity. Carers (n = 214) of individuals aged between 6 and 25 and experiencing outbursts at least once per month completed the Emotional Outburst Questionnaire. Questionnaire items were used to compare behaviours observed in most severe and least severe outbursts through quantitative and content analyses of open ended data. Signs of physiological arousal and aggression were seen significantly more in most severe outbursts compared to least severe outbursts. Least severe outbursts were seen more frequently, but most severe outbursts were reported to have a longer duration, be at a higher intensity, and have a longer recovery time. Additionally, associations were found between reduced eye contact and most severe outbursts, as well as expression of suicidal ideation and most severe outbursts. Certain behaviours, notably forms of aggression and physiological arousal, are associated with most severe outbursts. Findings of this study may allow future work examining cross-disorder differences in outbursts to inform targeted interventions aiming to reduce outburst severity and impact. Additionally, identification of such outburst characteristics could aid in measurement of outburst severity, which would allow for more reliable and valid studies on outburst interventions.

Theoretical-Methodological Foundations for the Global Integration Method (Método de Integração Global-MIG) in the Treatment of Autism Spectrum Disorder

Currently, there is no intervention model for autism spectrum disorder (ASD) that addresses all levels and factors of the International Classification of Functioning, Disability and Health (ICF, WHO). The most researched programs focus on naturalistic, developmental and behavioral approaches to socio-communication. Less attention has been paid to motor and environmental reactivity aspects (behavior/interest restriction and sensory reactivity). The evidence rationale for the Global Integration Method (MIG, "Método de Integração Global"), a model addressing sensorimotor reactivity in addition to socio-communication, is presented. MIG is an integrative, interdisciplinary, family-oriented intervention and naturalistic program that addresses all levels and moderating factors of ASD's impact. MIG's theoretical rationale is based on the predictive coding impairment and embodied cognition hypotheses. MIG incorporates both bottom-up (flexible therapeutic suit, social-motor synchronization) and top-down (schematic social information processing, narratives, imagery) strategies to promote the building and use of accurate, flexible and context-sensitive internal predictive models. MIG is based on the premises that predictive coding improves both socio-communication and environmental reactivity, and that the postural stabilization provided by the flexible therapeutic suit frees information processing resources for socio-cognitive learning. MIG builds on interdisciplinary, professionally and parentally mediated work based on behavioral principles of intensive training in a situated environment.

Brief Report: Exploratory Evaluation of Clinical Features Associated with Suicidal Ideation in Youth with Autism Spectrum Disorder

There has been a heightened awareness of an increased risk of suicidality among individuals with autism spectrum disorder (ASD) due to high rates of suicidal ideation (SI) in this population (11-66%). The current study investigated the rate of parent-endorsed SI and associated clinical features in 48 youths with ASD (Age; M: 12.97 years, SD: 2.33). SI was endorsed in 18.75% of participants. Youth with SI exhibited significantly higher levels of affective problems, externalizing problems, feelings of humiliation and rejection, and symptoms related to perfectionism. Results indicate that co-occurring mental health problems are associated with suicidal ideation and provide relevant targets for psychotherapeutic intervention. This preliminary study in a modest sample suggests the value of further research in larger samples to replicate and generalize these findings.

Use of ECT for Children With and Without Catatonia: A Single-Site Retrospective Analysis

OBJECTIVES

The objective study was to investigate the safety and efficacy of electroconvulsive therapy (ECT) in a retrospective cohort of pediatric patients.

METHODS

A single-site retrospective analysis was conducted of patients aged younger than 18 years who received ECT in a private university hospital from January 28, 2012 to April 8, 2023. Treatment efficacy and adverse events were determined retrospectively through review of the medical record.

RESULTS

A total of 36 pediatric patients met the inclusion criteria. Catatonia was the most common presenting indication for ECT, followed by psychosis and suicidal ideation. For all patients, Clinical Global Impressions-Improvement scale scores indicated that it was very likely for a subject to experience at least "much improvement" with the estimated probability of receiving a Clinical Global Impressions-Improvement scale score better than 3 of 0.852 (t.s. = 16.3; P < 0.001; 95% confidence interval, 0.711-0.931). All patients with catatonia demonstrated a positive clinical response and experienced a statistically significant reduction in total Bush-Francis Catatonia Rating Scale scores observed (t = 11.9; df = 20; SD = 6.3; P < 0.001; 95% confidence interval, 12.6-17.9). No significant adverse events were reported for any patient in the cohort. However, 14 (38.9%) patients experienced prolonged seizures, all of which were terminated with propofol (mean, 49.7 mg).

CONCLUSIONS

This study provides further data supporting the safe and effective use of pediatric ECT in the treatment of various psychiatric conditions. However, more research is needed to determine the risk factors associated with prolonged seizures and the optimal seizure parameters in young people.

The biosocial correlates and predictors of emotion dysregulation in autistic adults compared to borderline personality disorder and nonclinical controls

BACKGROUND

Emotion dysregulation (ED) is a core symptom of borderline personality disorder (BPD), whose aetiology has been attributed to biosocial factors. In autism spectrum condition (ASC), although ED is prevalent and is associated with decreased well-being (e.g. self-harm, suicidality), it has been understudied, especially in adults. It is therefore crucial to further understand ED in autistic adults to improve its treatment. Our study investigates ED, its behavioural correlates (e.g. self-harm, suicidality) and biosocial predictors in autistic adults relative to BPD and nonclinical controls (NC).

METHODS

A total of 724 participants (ASC = 154; BPD = 111; NC = 459) completed 11 self-reported questionnaires assessing ED, ASC and BPD traits, co-occurring disorders, alexithymia, emotional vulnerability and invalidating experiences (e.g. bullying, autistic camouflaging). The occurrence of ED behavioural correlates (i.e. self-harm, history of suicide attempts, and psychiatric hospitalizations) was collected. In addition, between-groups analyses, linear regressions and machine learning (ML) models were used to identify ED predictors in each group.

RESULTS

ED and its behavioural correlates were higher in ASC compared to NC, but milder than in BPD. While gender did not predict ED scores, autistic women had increased risk factors to ED, including sexual abuse and camouflaging. Interestingly, BPD traits, emotional vulnerability and alexithymia strongly predicted ED scores across the groups. Using ML models, sensory sensitivity and autistic camouflaging were associated with ED in ASC, and ADHD symptoms with ED in BPD.

LIMITATIONS

ASC and BPD diagnoses were self-reported, which did not allow us to check their accuracy. Additionally, we did not explore the transactional and the moderating/mediating relationships between the different variables. Moreover, our research is cross-sectional and cannot draw conclusions regarding the direction and causality of relationships between ED and other clinical dimensions.

CONCLUSIONS

ED and its behavioural correlates are heightened in BPD compared to ASC and nonclinical controls. In the ASC group, there were no gender differences in ED, despite the heightened exposure of autistic women to ED risk factors. BPD traits, emotional vulnerability, and alexithymia are core to ED regardless of diagnosis. Although less central, sensory sensitivity and autistic camouflaging seem to be specific predictors of ED in autistic adults.

Facilitators and barriers in psychotherapy from the perspective of autistic adults: an enhanced critical incident study

PURPOSE

A significant portion of autistic adults experience mental health challenges. Currently, the literature is incomplete when it comes to understanding the needs and preferences of autistic adults who receive therapy. This study elicited the perspectives of autistic adults, focusing on the facilitators, barriers and ways to enhance psychotherapy based on receiving this care for mental health problems.

METHODS

Using the qualitative, exploratory approach of the Enhanced Critical Incident Technique, eight autistic adults took part in interviews.

RESULTS

A total of 147 critical incidents were extracted from participant interviews and categories salient to therapeutic practice. The study identified key factors influencing therapy, such as trust and respect, practical approaches, client factors, structure of sessions, knowledge about autism, support for individualized needs, access to mental health services, and involvement of family/advocate. These factors were categorized into eight main areas relevant to therapeutic practice.

CONCLUSIONS

Findings from this research reveal that psychotherapy with autistic adults is analogous to performing this work with non-autistic adults, in the sense that this work too entails elements of individually tailored treatment and the reliance on common therapeutic factors. There are also differences in this work that necessitate providers having foundational knowledge about autism. Learning directly from autistic adults' insights may help to improve upon the delivery of mental health care for autistic adults.

Assessing suicidal thoughts and behaviors and nonsuicidal self-injury in autistic and non-autistic early adolescents using the Columbia Suicide Severity Rating Scale

LAY ABSTRACT

Autistic adolescents are more likely to experience suicidal thoughts and behaviors and nonsuicidal self-injury than non-autistic adolescents, per caregiver- and self-report on single-item questionnaires. Comprehensive, clinician-rated measures of suicide risk have not been used to measure suicidal thoughts and behaviors and nonsuicidal self-injury in autistic youth despite greater parent-child rating discrepancies among autistic youth than their non-autistic peers. The Columbia Suicide Severity Rating Scale is a widely used, clinician-rated measure of suicide risk that has not been tested with autistic youth. In this study, the Columbia Suicide Severity Rating Scale was employed to assess suicidal thoughts and behaviors and nonsuicidal self-injury in a community sample of 239 early adolescents (10:0-13:9 years old), of whom 138 youth were autistic and 101 were not autistic. Multiple analyses examined diagnostic (autistic vs non-autistic) and sex-based (male vs female) differences in suicidal thoughts and behaviors and nonsuicidal self-injury, as well as youth consistency in reporting across self- and clinician-rated measures. Findings show that a greater proportion of autistic youth reported lifetime suicidal thoughts and nonsuicidal self-injury than non-autistic youth; however, there were no sex-based differences. The majority of non-autistic youth were consistent in reporting suicidal thoughts on self- and clinician-rated measures; however, nearly one in five autistic youth disclosed suicidal thoughts on a self-report measure but not to a psychiatrist on the Columbia Suicide Severity Rating Scale. Findings suggest that autism diagnostic status, but not sex, confers significant risk for suicidal thoughts and behaviors and nonsuicidal self-injury in early adolescents and that the Columbia Suicide Severity Rating Scale may be a useful measure of suicide risk for some autistic youth, but it may not detect all autistic youth experiencing suicidal thoughts.

Suicide and non-fatal self-injury-related emergency department visits among individuals with autism spectrum disorder

LAY ABSTRACT

This study used data for 14.4 million individuals with 43.5 million emergency department visits from all hospitals in the state of New York to explore the association between suicide and non-fatal self-injury-related (self-injury) emergency department visits and autism spectrum disorder. Overall, we found that individuals with autism spectrum disorder had more emergency department visits and admissions through the emergency department, more years of emergency department utilization, and higher prevalence of mental health-related comorbidities. Individuals with autism spectrum disorder were also significantly more likely to have at least one self-injury-related emergency department visit compared to those without autism spectrum disorder. These results emphasize the need to raise awareness across both family caregivers and healthcare providers on the increased suicide and self-injury risks that individuals with autism spectrum disorder face and to improve care delivery practices. In addition, effort to promote and increase timely access to mental health care is an urgent priority for individuals with autism spectrum disorder.

Linehan's biosocial model applied to emotion dysregulation in autism: a narrative review of the literature and an illustrative case conceptualization

Emotion dysregulation (ED) is a transdiagnostic difficulty prevalent in autism spectrum condition (ASC). Importantly, recent research has suggested that ED is involved in self-harm and suicidality. Pre-existing models on the etiology of ED in ASC focus mainly on biological factors to ASC features, such as sensory sensitivities, poor flexibility, and sensitivity to change. However, although psychosocial factors seem to play a role in the emergence of ED in ASC as well (e.g., childhood maltreatment and camouflaging), there is a lack of a comprehensive model conceptualizing biosocial factors involved in ED in autistic people. Linehan's biosocial model (1993) is one of the leading etiological models of ED in borderline personality disorder (BPD). It conceptualizes ED as emerging from transactions between a pre-existing emotional vulnerability in the child and an invalidating developmental environment. Beyond its clinical relevance, Linehan's model has gathered empirical evidence supporting its pertinence in BPD and in other psychiatric disorders. Although ASC and BPD are two distinct diagnoses, because they may share ED, Linehan's biosocial model might be useful for understanding the development of ED in ASC. Hence, this article aims to provide an application and extension of Linehan's model to conceptualize ED in ASC. To do so, we conducted a narrative review of the literature on ED and its underlying factors in ASC from a developmental perspective. To investigate the pertinence of the biosocial model applied to ED in autistic people, we were interested on data on (i) ED and its behavioral correlates in ASC, in relation to the biosocial model, (ii) the potential biological and psychosocial correlates of ED in ASC and (iii) the overlapping difficulties in ASC and BPD. Finally, to assess the pertinence of the model, we applied it to the case of an autistic woman presenting with ED and suicidal behaviors. Our review and application to the case of an autistic woman suggest that ED in ASC encompasses factors related to both biological and psychosocial risk factors as conceptualized in the BPD framework, although in both domains ASC-specific factors might be involved.

Is camouflaging autistic traits associated with defeat, entrapment, and lifetime suicidal thoughts? Expanding the Integrated Motivational Volitional Model of Suicide

INTRODUCTION

The current study explored whether camouflaging autistic traits is associated with defeat and entrapment and lifetime suicidal thoughts, as predicted by the Integrated Volitional Model of Suicide (IMV model).

METHODS

180 UK undergraduate students (76.7% female 18-67 years) completed a cross-sectional online survey from February 5 to March 23, 2020, including self-report measures of defeat and entrapment (SDES), autistic traits (AQ-10), depression (PHQ-9), anxiety (GAD-7), camouflaging autistic traits (CAT-Q), and lifetime suicidal thoughts and behaviors (SBQ-R item 1).

RESULTS

After controlling for age, gender, current depression, and anxiety symptoms, autistic traits accounted for significantly more of the variance in defeat and entrapment (1.1%), and camouflaging accounted for a further 3.2% of the variance. The association between autistic traits and lifetime suicidality was significantly mediated by camouflaging, defeat, and entrapment. After controlling for age, gender, current depression, and anxiety symptoms, defeat and entrapment (but not camouflaging) accounted for significantly more variance in lifetime suicidal thoughts. The interaction between camouflaging, defeat and entrapment predicted significantly less variance in lifetime suicidal thoughts than either variable alone.

CONCLUSION

Results suggest that camouflaging autistic traits is a transdiagnostic risk factor for lifetime suicidality, relevant to the defeat and entrapment constructs of the IMV model.

The role of the broader autism phenotype in anxiety and depression in college-aged adults

The current study examines the relationship between the presence of autistic traits and anxiety and mood disorders in young adults from different racial groups. A representative sample from a predominately white university (2,791 non-Hispanic White (NHW) and 185 Black students) completed the broad autism phenotype questionnaire (BAPQ), a measure of depression (Patient Health Questionnaire, PHQ-9), and anxiety (Generalized Anxiety Disorder, GAD-7). Statistical Package for Social Sciences (SPSS) was used to perform two multiple regression analyses to determine the association between race, BAPQ score and anxiety and depression symptoms. The current study found a stronger association between autistic traits had depression and anxiety symptoms in Black participants than did NHW participants. These findings underscore the association between autistic traits and anxiety and depression in Black communities, and the need for further studies on this topic area. Additionally, it highlights the importance of improving access to mental health care for this population.

Health Care Disparities Among Autistic LGBTQ+ People

Background

Lesbian, gay, bisexual, transgender, or queer (LGBTQ+) people and disabled people experience disparities in access to health care compared with others. However, we have yet to understand how health care disparities may be further exacerbated at the intersection of disability and LGBTQ+ identity, particularly among autistic people.

Objectives

The primary goals of this study were to (1) examine differences in unmet health care needs and health status between LGBTQ+ autistic people and straight/cisgender autistic people and (2) explore how state policies and demographics predict the unmet health care needs of the autistic LGBTQ+ people.

Methods

We conducted a cross-sectional analysis using data from the 2019 National Survey on Health and Disability that included a subsample of autistic participants, with 62 LGBTQ+ adults and 58 straight/cisgender adults. To address our first study goal, we used an independent samples t-test, and to address our second study goal, we used Poisson regression.

Results

The LGBTQ+ group reported significantly more days of poor physical and mental health, more co-occurring diagnoses, and more unmet health care needs than the straight/cisgender group. For LGBTQ+ people, protective state health care laws and a lower income resulted in significantly more health care needs being met.

Conclusions

Findings from this study suggest that the intersection of an LGBTQ+ identity and autism is associated with greater disparities in physical and mental health as well as unmet health care needs; however, state policies prohibiting discrimination of LGBTQ+ people may act as a protective factor and result in fewer unmet health care needs. Future research should examine additional structural factors that may mitigate health inequities for autistic LGBTQ+ people.

Unlocking the Secrets: Exploring the Biochemical Correlates of Suicidal Thoughts and Behaviors in Adults with Autism Spectrum Conditions

Involving 1 million people a year, suicide represents one of the major topics of psychiatric research. Despite the focus in recent years on neurobiological underpinnings, understanding and predicting suicide remains a challenge. Many sociodemographical risk factors and prognostic markers have been proposed but they have poor predictive accuracy. Biomarkers can provide essential information acting as predictive indicators, providing proof of treatment response and proposing potential targets while offering more assurance than psychological measures. In this framework, the aim of this study is to open the way in this field and evaluate the correlation between blood levels of serotonin, brain derived neurotrophic factor, tryptophan and its metabolites, IL-6 and homocysteine levels and suicidality. Blood samples were taken from 24 adults with autism, their first-degree relatives, and 24 controls. Biochemical parameters were measured with enzyme-linked immunosorbent assays. Suicidality was measured through selected items of the MOODS-SR. Here we confirm the link between suicidality and autism and provide more evidence regarding the association of suicidality with increased homocysteine (0.278) and IL-6 (0.487) levels and decreased tryptophan (-0.132) and kynurenic acid (-0.253) ones. Our results suggest a possible transnosographic association between these biochemical parameters and increased suicide risk.

A systematic review and meta-analysis of suicidality in autistic and possibly autistic people without co-occurring intellectual disability

BACKGROUND

Suicidality is highly prevalent in autistic people without co-occurring intellectual disabilities, and high autistic traits are found in adults who have attempted suicide. However, prevalence rates for both autistic and possibly autistic people have not been synthesised meta-analytically.

AIMS

To (1) calculate pooled prevalence estimates of suicidality in autistic people and possibly autistic people without co-occurring intellectual disability; (2) evaluate the influence of participant and study level characteristics on heterogeneity; and (3) determine the quality of evidence.

METHODS

Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed. PsycINFO, Embase, MEDLINE and Web of Science were systematically searched from 1992 to January 25, 2022. Empirical quantitative studies reporting prevalence of suicidal ideation, suicide plans, or suicide attempts and behaviours were considered for inclusion. Random effects models were used to estimate pooled prevalence of each suicidality outcome with 95% confidence intervals. Heterogeneity was explored using sensitivity and moderator analyses.

RESULTS

Data from 48,186 autistic and possibly autistic participants in 36 primary studies were meta-analysed. Pooled prevalence of suicidal ideation was 34.2% (95% CI 27.9-40.5), suicide plans 21.9% (13.4-30.4), and suicidal attempts and behaviours 24.3% (18.9-29.6). High levels of heterogeneity (I² > 75) were observed in all three analyses. Estimates did not differ between autistic or possibly autistic samples. Geographical location (p = 0.005), transgender or gender non-conforming samples (p < 0.001) and type of report (p < 0.001) significantly moderated suicidal ideation, whereas age group (p = 0.001) and measure of suicidality (p = 0.001) significantly moderated suicide plans. There was a significant association between the proportion of male participants and prevalence of suicide plans, with a decrease in the proportion of males for every unit change of suicide plan prevalence (p = 0.013). No variables were found to moderate estimates of suicide attempts and behaviours.

CONCLUSIONS

The results confirm suicidality is highly prevalent in both autistic and possibly autistic people without co-occurring intellectual disability and highlights potential moderators. Possibly autistic individuals require more attention in clinical and research considerations going forward to further understand and prevent suicide in both groups.

The impact of sleep quality, fatigue and social well-being on depressive symptomatology in autistic older adolescents and young adults

Depression and poor sleep quality commonly co-occur with autism, and depression has been associated with loneliness and reduced social support. In non-autistic samples, poor sleep quality and daytime fatigue also contribute to depression. However, the contribution of sleep quality and fatigue to depressive symptoms, and how they interact with social factors to influence depression in autism remain unexplored. Our aim was to examine these relationships in 114 young autistic adults aged 15-25 years (57% male) from the SASLA online, longitudinal study (baseline and 2-year follow-up). Hierarchical multiple regression models examined the association between social well-being (social integration and social contribution; T1), sleep quality (T1, T2), and fatigue (T1, T2) on depression (T1, T2). Two mediation models were conducted on T1 data predicting depression from sleep quality though fatigue and sleep quality through social well-being. Depression and fatigue scores did not change over 2 years, but sleep quality worsened. The T1 regression model was significant (R² = 36%) with fatigue and social contribution individually predicting depression symptomatology. The longitudinal regression model was also significant (adjusted R² = 57%) with social contribution (T1) as the only significant predictor of depression (T2). Fatigue trended towards mediating the sleep quality-depression relationship, while social well-being was a significant partial mediator of this relationship. Results highlight that sleep quality, fatigue, and social well-being contribute to depression among young autistic adults. Interestingly, fatigue and social well-being were independently associated with depression. Thus, addressing sleep quality and associated fatigue, and social well-being is important when treating depression in autistic individuals.

A systematic review of predictors of suicidal thoughts and behaviors among autistic adults: Making the case for the role of social connection as a protective factor

Autistic adults are a high-risk population for suicidal thoughts and behaviors (STBs). Accordingly, this systematic review aims to review the prevalence of STBs among autistic adults, review the risk and protective factors for STBs in autistic adults, and formulate a disorder-specific conceptualization of risk in this population. We systematically searched PsycINFO and Google Scholar for all studies published prior to March 28th, 2022. We included empirical articles focused on autistic adults, ages 18 years and older, reporting on suicide-related outcomes. In total, 45 peer-reviewed empirical articles were included in the current systematic review. The most frequently studied factors in relation to suicide risk among autistic adults were interpersonal constructs (42.4% of total studies looking at risk/protective factors) and depressive symptoms (36.4% of total studies looking at risk/protective factors). We conclude by summarize two key content areas: exploring social and interpersonal constructs and better understanding the role of depressive symptoms in autism. As researchers continue to explore STBs among autistic adults, it will be necessary to addressing the overreliance on autistic symptoms instead of autism diagnoses, measurement issues of STBs, and a need for treatment adaptations.

Advancing research on early autism through an integrated risk and resilience perspective

To date, a deficit-oriented approach dominates autism spectrum disorder (ASD) research, including studies of infant siblings of children with ASD at high risk (HR) for the disabilities associated with this disorder. Despite scientific advances regarding early ASD-related risk, there remains little systematic investigation of positive development, limiting the scope of research and quite possibly a deeper understanding of pathways toward and away from ASD-related impairments. In this paper, we argue that integrating a resilience framework into early ASD research has the potential to enhance knowledge on prodromal course, phenotypic heterogeneity, and developmental processes of risk and adaptation. We delineate a developmental systems resilience framework with particular reference to HR infants. To illustrate the utility of a resilience perspective, we consider the "female protective effect" and other evidence of adaptation in the face of ASD-related risk. We suggest that a resilience framework invites focal questions about the nature, timing, levels, interactions, and mechanisms by which positive adaptation occurs in relation to risk and developmental pathways toward and away from ASD-related difficulties. We conclude with recommendations for future research, including more focus on adaptive development and multisystem processes, pathways away from disorder, and reconsideration of extant evidence within an integrated risk-and-resilience framework.

Community-guided measurement-based care for autistic youth and adults receiving psychotherapy: A conceptual overview and pilot implementation study of MBC-AUT

LAY ABSTRACT

Autistic youth and adults are more likely to experience psychiatric symptoms (e.g. depression, anxiety) and to use psychiatric services than non-autistic people, yet research on evidence-based approaches to enhance psychiatric care for autistic people is limited. Measurement-based care is an evidence-based approach to psychotherapy that improves outcomes for clients, clinicians, and organizations by routinely administering and evaluating measures to clients. Despite this, research on measurement-based care systems for autistic clients is sparse. To address this gap, we developed an autism-adapted measurement-based care (MBC-AUT) system for and with autistic people and pilot tested the system in an outpatient psychiatry clinic to investigate the preliminary feasibility, acceptability, benefits, and barriers to this system for clients and clinicians. Findings suggested that the MBC-AUT system was a feasible and acceptable system for the first 18 autistic youth, their caregivers, and autistic adults to use the system. In semi-structured interviews, clients and clinicians discussed the benefits of the MBC-AUT system to various therapeutic processes, as well as several important barriers to the use of the system. We offer potential solutions to address these barriers and to reduce client and clinician burden, and propose future directions for this line of research to increase access to more autistic people. As autistic clients continue to seek psychological services amid social landscapes of increasing complexity (e.g. COVID-19 pandemic), efforts to enhance the delivery of psychotherapy for this population are critical.

A Scoping Review of Autism and the Way It Changes the Presentation of Suicidal Thoughts and Behavior Compared to the General Population

Autism spectrum conditions are a group of neurodevelopmental conditions that carries an array of co-occurring diagnoses, including a heightened risk of suicide attempts and suicide. This scoping review examined primary research focusing on autism and suicidality, to understand what is currently known on the topic, including how autism changes the presentation of suicidal thoughts and behavior; and to assess the suicide awareness and prevention education programs currently available for autistic people, their families, and health professionals and support workers. A comprehensive search (November 2021) across Scopus, PubMed and CINAHL identified 39 articles from 38 studies. Three themes emerged, with five subthemes. 1. The prevalence of suicidality in autistic people; 2. The presentation of suicidality in autistic people, including (a) risk of suicidality; (b) gender, age, employment and education; (c) co-occurring psychiatric conditions; (d) autism traits and social communication; (e) intellectual disability; and 3. Autism-specific approaches to suicidal thoughts, behavior and prevention. Findings were mixed, including conflicting evidence on the risk of autism and suicidality, and limited evidence of resources related to autism-specific suicide awareness or information, and education or prevention programs.

A capabilities approach to understanding and supporting autistic adulthood

There is little comprehensive research into autistic adulthood, and even less into the services and supports that are most likely to foster flourishing adult autistic lives. This limited research is partly because autism is largely conceived as a condition of childhood, but this focus of research has also resulted from the orthodox scientific approach to autism, which conceptualizes autistic experience almost entirely as a series of biologically derived functional deficits. Approaching autism in this way severely limits what is known about this neurodevelopmental difference, how research is conducted and the services and supports available. In this Review, we adopt an alternative research strategy: we apply Martha Nussbaum’s capabilities approach, which focuses on ten core elements of a thriving human life, to research on autistic adulthood. In doing so, we identify areas where autistic adults thrive and where they often struggle, and highlight issues to which researchers, clinicians and policymakers should respond. The resulting picture is far more complex than conventional accounts of autism imply. It also reveals the importance of engaging autistic adults directly in the research process to make progress towards genuinely knowing autism and supporting flourishing autistic lives.

The focus on functional deficits in conventional autism research constrains understanding of autistic lives. In this Review, Pellicano et al. appraise research on autistic adulthood through a capabilities lens to identify areas where autistic adults thrive, and where more research and services are needed to enhance their quality of life.

Predictors of Suicide Attempts of Individuals with Autism and Their Siblings

The occurrence of mood- and anxiety-related conditions among family members of individuals diagnosed with autism spectrum disorder (ASD) increases the risk of suicide attempts and has also created assessment and treatment issues for clinicians and parents. Recorded rates of mental health disorders comorbid with suicide attempts among individuals on the spectrum range from 29% to 52%. The purpose of this study was to investigate the presence of predictors of suicide attempts among sibling dyads (pairs of siblings in which one sibling is on the autism spectrum). Growing evidence in the literature indicates a link between a diagnosis of autism and mental health. A web-based survey was used to collect data from individuals on the spectrum and their siblings. A sample of 144 individuals was finalized for the analyses. Logistic regression analysis was conducted to assess the predictors of suicide attempts in the sample. Depression, anxiety, sexual orientation, and marital status were all used as predictors in the logistic regression analyses. Both levels of anxiety and sexual orientation were found to be significant predictors for suicide attempts. Recommendations for future research, assessment, and treatment are presented.

Parent-Reported Suicidal Ideation in Three Population-Based Samples of School-Aged Korean Children With Autism Spectrum Disorder and Autism Spectrum Screening Questionnaire Screen Positivity

OBJECTIVES

Higher prevalence of suicidality has been reported in individuals with ASD. This study aimed to (1) Estimate the prevalence of suicidal ideation (SI) in epidemiologically-ascertained, population-based, samples of children with ASD or Autism Spectrum Screening Questionnaire (ASSQ) Screen Positivity (ASP); (2) Determine whether ASD/ASP is an independent risk factor for SI, controlling for known SI risk factors; and, (3) Develop an explanatory model for SI in children with ASD/ASP.

METHODS

Participants came from three epidemiologically-ascertained samples of school-aged Korean children (n = 14,423; 3,702; 4,837). ASSQ ≥ 14 was the cutoff for ASP. A subsample (n = 86) was confirmed to have ASD. SI was based on parents' endorsement of items on the Behavioral Assessment System for Children-2-Parent Report Scale-Children. Logistic regressions were used to assess associations between SI and ASD/ASP, controlling for demographics, peer victimization, behavior problems, and depression. To develop an explanatory model for SI within ASD/ASP, the associations between SI and child characteristics (comorbid conditions, ASD symptoms, IQ, adaptive function) were tested.

RESULTS

SI was higher in children with ASD (14%) and ASP (16.6-27.4%) than ASSQ Screen Negative (ASN) peers (3.4-6.9%). ASD/ASP was strongly predictive of SI (ORs: 2.87-5.67), after controlling for known SI risk factors compared to ASN. Within the ASD and ASP groups, anxiety was the strongest predictor of SI.

CONCLUSIONS

SI prevalence was higher in non-clinical samples of children with ASD and ASP, relative to ASN peers. These results underscore the need for routine screening for SI in children with ASD and social difficulties, particularly those with high anxiety. HighlightsPopulation-based, epidemiologically-ascertained, school-aged childrenASD and ASP are independent risk factors for SI in school-aged childrenAnxiety is an independent risk factor for SI in children with ASD or ASP.

Children and Young People Presenting in a Pediatric Emergency Department in North-West England in Suicidal Crisis: An Exploratory Case Series Study

Suicide is a leading cause of death among children and young people (CYP) worldwide, and rates have been increasing in recent years. However, while evidence exists regarding factors associated with suicide and self-harm, there is limited information publicly available on the CYP who present in suicidal crisis. This is a case series study of CYP (aged 8-16) experiencing suicidal crisis who presented in an Emergency Department at a pediatric hospital in North-West England between March 2019 and March 2021 (n = 240). Clinical records were extracted and audited to explore demographic data, methods of recording patient attendance, the clinical pathways available and the patterns of pathway usage, and differences in CYP presentations before and after the COVID-19 pandemic. Attendees were mostly White females, with a mean age of 13.5 years, and 24% had a diagnosed special educational need. "Social/social problems" was the most commonly used code for recording attendance (38%), and pathways varied depending on code used. A range of parental and familial factors were also identified. There were more CYP presenting with self-harm in addition to suicide ideation after the pandemic began (43 vs 27% pre-pandemic). This study provides the first clear insight into CYP who seek help at a North-West Emergency Department for suicidal crisis, and work is now needed to develop effective prevention strategies tailored toward the groups most at-risk.

The relevance of the interpersonal theory of suicide for predicting past-year and lifetime suicidality in autistic adults

Background

While there are known risk factors for suicidality in autistic adults, these are often unconnected from theoretical frameworks that might explain why risk is elevated and guide clinical interventions. The present study investigated the relevance of constructs from the Interpersonal Theory of Suicide (ITS), including perceived burdensomeness, thwarted belongingness and acquired capability for suicide, and explored mechanisms through which certain risk factors (relationship status, age at diagnosis) might elevate suicide risk.

Methods

Autistic adults (n = 314) completed an online study including measures of depression, anxiety and constructs from the ITS. Linear and multinomial regression analysis disentangled contributions of ITS variables from effects of depression and anxiety for past-year suicide ideation, past-year and lifetime suicide attempts. Mediation analyses examined associations between risk factors and these suicide outcomes via mechanisms proposed by the ITS.

Results

Past-year suicide ideation was associated with burdensomeness, mental rehearsal of suicide plans (a facet of acquired capability), and depression. Greater feelings of burdensomeness, and reduced fear of death, marked out participants who had attempted suicide in comparison to those who had experienced suicide ideation in the past year. Relationship status was indirectly associated with past-year suicide ideation via the mediators of depression and burdensomeness, and was associated with past-year attempts via its effect on ideation. Age at diagnosis was unrelated to any variables.

Limitations

Cross-sectional research is insensitive to causality and temporal dynamics, which is likely why interaction hypotheses from the ITS were unsupported. Normative measures may be invalid in autistic samples. There was no control group. The autistic sample was unrepresentative of the whole population, particularly autistic people with intellectual disabilities, ethnic/racial minorities, and gender minorities.

Conclusions

Perceived burdensomeness and acquired capability appear potentially important to suicide in autistic people, and may mediate the effects of some risk factors. Future research should explore the temporal dynamics of suicide trajectories in longitudinal, prospective designs.

Efficacy and safety of balovaptan for socialisation and communication difficulties in autistic adults in North America and Europe: a phase 3, randomised, placebo-controlled trial

BACKGROUND

There are no approved pharmacological therapies to support treatment of the core communication and socialisation difficulties associated with autism spectrum disorder in adults. We aimed to assess the efficacy, safety, and pharmacokinetics of balovaptan, a vasopressin 1a receptor antagonist, versus placebo in autistic adults.

METHODS

V1aduct was a phase 3, randomised, placebo-controlled, double-blind trial, conducted at 46 sites across six countries (the USA, the UK, France, Italy, Spain, and Canada). Eligible participants were aged 18 years or older with an intelligence quotient (IQ) of 70 or higher, and met the criteria for moderate-to-severe autism spectrum disorder (DSM-5 and Autism Diagnostic Observation Schedule). Participants were randomly allocated (1:1), with an independent interactive voice or web-based response system, to receive balovaptan (10 mg) or placebo daily for 24 weeks. Randomisation was stratified by an individual's baseline Vineland-II two-domain composite (2DC) score (<60 or ≥60), sex, region (North America or rest of world), and age (<25 years or ≥25 years). Participants, study site personnel, and the sponsor were masked to treatment assignment. The primary endpoint was change from baseline in Vineland-II 2DC score (the mean composite score across the Vineland-II socialisation and communication domains) at week 24. The primary analysis was done with ANCOVA in the intention-to-treat population. The V1aduct study was terminated for futility after around 50% of participants completed the week 24 visit. This trial is registered with ClinicalTrials.gov (NCT03504917).

FINDINGS

Between Aug 8, 2018, and July 1, 2020, 540 people were screened for eligibility, of whom 322 were allocated to receive balovaptan (164 [51%]) or placebo (158 [49%]). One participant from the balovaptan group was not treated before trial termination and was excluded from the analysis. 60 participants in the balovaptan group and 55 in the placebo group discontinued treatment before week 24. The sample consisted of 64 (20%) women and 257 (80%) men, with 260 (81%) participants from North America and 61 (19%) from Europe. At baseline, mean age was 27·6 years (SD 9·7) and mean IQ score was 104·8 (18·1). Two (1%) participants were American Indian or Alaska Native, eight (2%) were Asian, 15 (5%) were Black or African American, 283 (88%) were White, four (1%) were of multiple races, and nine (3%) were of unknown race. Mean baseline Vineland-II 2DC scores were 67·2 (SD 15·3) in the balovaptan group and 66·2 (17·7) in the placebo group. The interim futility analysis showed no improvement for balovaptan versus placebo in terms of Vineland-II 2DC score at week 24 compared with baseline, with a least-squares mean change of 2·91 (SE 1·52) in the balovaptan group (n=79) and 4·75 (1·60) in the placebo group (n=71; estimated treatment difference -1·84 [95% CI -5·15 to 1·48]). In the final analysis, mean change from baseline in Vineland-II 2DC score at week 24 was 4·56 (SD 10·85) in the balovaptan group (n=111) and 6·83 (12·18) in the placebo group (n=99). Balovaptan was well tolerated, with similar proportions of participants with at least one adverse event in the balovaptan group (98 [60%] of 163) and placebo group (104 [66%] of 158). The most common adverse events were nasopharyngitis (14 [9%] in the balovaptan group and 19 [12%] in the placebo group), diarrhoea (11 [7%] and 14 [9%]), upper respiratory tract infection (ten [6%] and nine [6%]), insomnia (five [3%] and eight [5%]), oropharyngeal pain (five [3%] and eight [5%]), and dizziness (two [1%] and ten [6%]). Serious adverse events were reported for two (1%) participants in the balovaptan group (one each of suicidal ideation and schizoaffective disorder), and five (3%) participants in the placebo group (one each of suicidal ideation, panic disorder, limb abscess, urosepsis, colitis [in the same participant with urosepsis], and death by suicide). No treatment-related deaths occurred.

INTERPRETATION

Balovaptan did not improve social communication in autistic adults. This study provides insights into challenges facing autism spectrum disorder trials, including the considerable placebo response and the selection of appropriate outcome measures.

What Is Autistic Burnout? A Thematic Analysis of Posts on Two Online Platforms

Background

Compared with adults in the general population, autistic adults are more likely to experience poor mental health, which can contribute to increased suicidality. While the autistic community has long identified autistic burnout as a significant mental health risk, to date, only one study has been published. Early research has highlighted the harmful impact of autistic burnout among autistic adults and the urgent need to better understand this phenomenon.

Methods

To understand the lived experiences of autistic adults, we used data scraping to extract public posts about autistic burnout from 2 online platforms shared between 2005 and 2019, which yielded 1127 posts. Using reflexive thematic analysis and an inductive "bottom-up" approach, we sought to understand the etiology, symptoms, and impact of autistic burnout, as well as prevention and recovery strategies. Two autistic researchers with self-reported experience of autistic burnout reviewed the themes and provided insight and feedback.

Results

We identified eight primary themes and three subthemes across the data. (1) Systemic, pervasive lack of autism awareness. (1.1) Discrimination and stigma. (2) A chronic or recurrent condition. (3) Direct impact on health and well-being. (4) A life unlived. (5) A blessing in disguise? (6) Self-awareness and personal control influence risk. (6.1) "You need enough balloons to manage the weight of the rocks." (7) Masking: Damned if you do, damned if you don't. (8) Ask the experts. (8.1) Stronger together. The overarching theme was that a pervasive lack of awareness and stigma about autism underlie autistic burnout.

Conclusions

We identified a set of distinct yet interrelated factors that characterize autistic burnout as a recurring condition that can, directly and indirectly, impact autistic people's functioning, mental health, quality of life, and well-being. The findings suggest that increased awareness and acceptance of autism could be key to burnout prevention and recovery.

Missed diagnoses and misdiagnoses of adults with autism spectrum disorder

Autism spectrum disorder (ASD) is a group of life-long neurodevelopmental disorders affecting 1.5% of the general population. The present study aimed to evaluate the psychiatric history of a group of adults who received the first diagnosis of ASD in two Italian university centers. Diagnoses of ASD were confirmed by a team of psychiatrists with wide expertise in the field, after the administration of standardized tools (i.e., ADOS-2, ADI-R). The sample comprised 161 participants, of which 114 (79.5%) were males. The median age of diagnosis was 23 years (range 18-55), with a median IQ of 100 (range 30-145). The first evaluation by a mental health professional was performed at a median age of 13 years, with a gap of 11 years between the first evaluation and the diagnosis of ASD. 33.5% of participants had never received a psychiatric diagnosis, while the rest of the sample had received one or more diagnoses different from ASD. The most common past diagnoses were intellectual disability, psychoses, personality disorders, and depression. Sex differences were detected in the age of diagnosis and ADOS-2 scores. Our results provide important information for both child and adult psychiatrists. Given the prevalence of autism and the high rates of co-occurrent psychiatric conditions, it is important for clinicians to consider ASD in the differential diagnostic process.

Characteristics and outcomes of referrals to CAMHS for children who are thinking about or attempted suicide: A retrospective cohort study in two Scottish CAMHS

Suicide among children and young people (CYP) is a leading cause of death. In the UK children identified as suicidal are referred to Child and Adolescent Mental Health Services (CAMHS) for assessment and treatment. However, the number of children referred for suicidality, and their care journey is unknown. This retrospective cohort study conducted in two distinct CAMHS teams, in Scotland, UK, aimed to quantify the numbers of children referred for suicidality, describing this population and the outcomes of these referrals. All CAMHS referrals (n = 1159) over a 6-month period (Jan-June 2019) were screened to identify those referred primarily for suicidality. Data extracted included: age, gender, source of referral, reason for referral including underlying issues, whether offered an assessment, and referral outcome. Area based deprivation scores were attached to each referral. Associations between the referred CYP's characteristics (including source of referral and underlying issues) and referral outcomes were explored using Chi Square, Fishers Exact test, and one-way ANOVA. Referrals for 284 children were identified as being for suicidality across the two sites (Site A n = 104; Site B n = 180). These represented 25% of all referrals to these CAMHS over a six-month period. One third of these concerned children under 12. The underlying issues, referrals sources, and demographic indicators were similar in both sites. In site A 31% were offered an assessment, whilst in Site B which had a dedicated team for suicidal CYP, 82% were offered an assessment. Similarly, more children in Site B were offered treatment (47.8%), than Site A (7.7%). Referrals from A&E were prioritized in both areas, and those who had attempted suicide offered an assessment more often. Older children were more likely to be offered treatment, although they were more likely to present with a history of self-harming behavior and/or previous suicide attempt. There are high numbers of children being referred to CAMHS for suicidality, and many are young children (<12). There is variation within and between services in terms of assessment, referral outcomes and care pathways for these children. Having a dedicated team to respond to referrals for suicidality appears to support access to assessment and treatment.

Adults with Autism: Changes in Understanding Since DSM-111

Over the past four decades there have been significant advances in our understanding of autism, yet services for autistic adults continue to lag far behind those for children, and prospects for employment and independent living remain poor. Adult outcomes also vary widely and while cognitive and language abilities are important prognostic indicators, the influence of social, emotional, familial and many other factors remains uncertain. For this special issue marking the 40th anniversary of DSM-III, the present paper describes the changing perspectives of autism in adulthood that have occurred over this period, explores individual and wider environmental factors related to outcome, and suggests ways in which services need to be changed to improve the future for adults living with autism.

A blind spot in mental healthcare? Psychotherapists lack education and expertise for the support of adults on the autism spectrum

Most adults on the autism spectrum have co-occurring mental health conditions, creating a high demand for mental health services – including psychotherapy – in autistic adults. However, autistic adults have difficulties accessing mental health services. The most-reported barriers to accessing treatment are therapists’ lack of knowledge and expertise surrounding autism, as well as unwillingness to treat autistic individuals. This study was conducted by a participatory autism research group and examined 498 adult-patient psychotherapists on knowledge about autism and self-perceived competency to diagnose and treat autistic patients without intellectual disability compared to patients with other diagnoses. Psychotherapists rated their education about autism in formal training, and competency in the diagnosis and treatment of patients with autism, lowest compared to patients with all other diagnoses surveyed in the study, including those with comparable prevalence rates. Many therapists had misconceptions and outdated beliefs about autism. Few had completed additional training on autism, but the majority were interested in receiving it. Greater knowledge about autism was positively linked to openness to accept autistic patients. The results point to an alarming gap in knowledge necessary for adequate mental health care for individuals with autism.

Psychedelic-Assisted Therapy for Social Adaptability in Autistic Adults

Access to the Internet has upended long-standing myths and misconceptions about autism as autistic individuals are enabled through technology increasingly to influence the dialog around neurodiversity, the experience of being autistic, and the effectiveness of mental health interventions for autistic adults. Autistic self-advocates are speaking up in support of including neurodivergent adults as a population that might benefit from the burgeoning psychedelic medicine field, in an absence of many other mental health treatment options that have been researched and shown to be effective for them. Autism is a genetically-determined neurocognitive variant with considerable heterogeneity across the broad autistic phenotype spectrum. Therefore, enthusiasm for investigating psychedelics to cure or alter the course of autism is most likely ill-informed and misdirected; psychiatric and psychopharmacological interventions do not alter the genome. However, autism frequently co-occurs with clinical conditions such as anxiety, depression, obsessive-compulsive disorder, and trauma that have been investigated as indications for clinical trials with classic and atypical psychedelics. The purpose of this chapter will be to inform researchers and clinicians on the history of clinical research with classic psychedelics with autistic minors, recent and current clinical trials of atypical psychedelics with autistic adults, and considerations for providing psychedelic-assisted psychotherapies that are compatible with autism.

Feasibility, Acceptability and Preliminary Efficacy of Dialectical Behavior Therapy for Autistic Adults without Intellectual Disability: A Mixed Methods Study

Self-harm and suicidal behaviors are prevalent among autistic adults without intellectual disability (ID). Emotion dysregulation (ED), the difficulty in modulating emotions, has been identified as an important risk factor. Dialectical behavior therapy (DBT) has been proved effective to treat ED in disorders other than autism spectrum disorder. Our study aimed at assessing the feasibility, acceptability and preliminary efficacy of DBT in seven autistic adults without ID exhibiting self-harm and/or suicidal behaviors linked to severe ED. Our results suggest that DBT is feasible and highly acceptable to autistic adults without ID. Additionally, mean scores on the Difficulties in Emotion Regulation Scale decreased significantly post-treatment and at 4-month follow-up, suggesting that DBT might be efficacious in reducing ED in this population.

Overlap of autism spectrum disorder and borderline personality disorder: A systematic review and meta-analysis

Autism spectrum disorder (ASD) and borderline personality Disorder (BPD) share features, including social and emotion regulation difficulties. The evidence for the overlap in prevalence and clinical characteristics was systematically reviewed. Ovid Medline, PsycInfo, and PubMed were searched until November 30, 2020 using keywords relating to BPD and ASD. Studies that reported on the overlap of ASD and BPD diagnoses or traits and used a case, cohort, or case-controlled design were included. Of 1633 screened studies, 19 were included, of which 12 reported data suitable for meta-analysis. Most samples were of small, clinically ascertained groups, with 11 having high risk of bias. The pooled prevalence of BPD in ASD was 4% [95% CI 0%-9%] and of ASD in BPD, 3% [95% CI 1%-8%]. There were inconsistent findings across clinical areas. The prevalence of a dual diagnosis of BPD in ASD cohorts and of ASD in BPD cohorts was within population prevalence estimates of each disorder. Based on this data we were not able to assess whether there is misdiagnosis of one in favor of the other. Neurocognitive differences may underlie similar behavioral symptoms, but further research using larger, well-validated samples is needed. LAY SUMMARY: Autism spectrum disorder (ASD) and borderline personality disorder (BPD) have overlaps in their symptoms. The overlap in how frequently they co-occur and their presentation was systematically reviewed. We searched the key databases and including all studies that reported on the overlap of ASD and BPD diagnoses or traits and used a case, cohort or case-controlled design. Of 1633 studies, 19 were included, of which 12 reported data suitable for pooling. Most samples were of small, clinical groups, with 11 having high risk of bias. The pooled prevalence of BPD in ASD was 4% [95% CI 0%-9%] and of ASD in BPD, 3% [95% CI 1%-8%]. There were inconsistent findings across studies comparing ASD and BPD related symptoms and problems. The prevalence of a dual diagnosis of BPD in ASD cohorts and of ASD in BPD cohorts was similar to the population prevalence of each disorder. Further research using larger, well-validated samples is needed.

The association between COVID-19, personal wellbeing, depression, and suicide risk factors in Australian autistic adults

The COVID‐19 pandemic has had a significant impact on the mental health and wellbeing of the world's population, with particularly negative effects on vulnerable populations, including autistic people. Although some consensus regarding specific impact on aspects of wellbeing and mental health in autism is starting to emerge, it is unclear whether the pandemic has increased suicide risk. The goals of this study were to examine (a) potential associations between COVID‐19 impact and depression, personal wellbeing, and suicide risk factors in Australian autistic adults and (b) age and gender effects. The COVID‐19 Impact Scale (CIS), Personal Wellbeing Index, Patient Health Questionnaire, and the Suicide Behavior Questionnaire, Revised (SBQ‐R), were administered to 111 autistic adults aged 20 to 71 years during the second wave of the COVID‐19 pandemic in Australia. COVID‐19 impact showed small associations with poorer personal wellbeing (r = −0.224, p = 0.023, [−0.409, −0.016]) and higher depressive symptoms (r = 0.268, p = 0.006, [0.056, 0.445]) and was not associated with the SBQ‐R suicide risk score (r = 0.081, p = 0.418, [−0.118, 0.264). No significant effects were identified for age. Although model results were similar for women and men, the strength of the associations between personal wellbeing and depression (z = −2.16, p = 0.015), and depression and SBQ‐R suicide risk (z = 1.961, p = 0.025), were stronger in women than in men. Qualitative analysis of an open response question from the CIS suggested that the pandemic had both positive and negative impacts on participants. The COVID‐19 pandemic has had a large impact on the mental health and wellbeing of the world's population, particularly vulnerable populations such as autistic people. It is not known if these impacts on mental health and wellbeing have increased suicide risk. Our findings suggest that the impact of the COVID‐19 pandemic may be associated with poorer wellbeing and higher depression, but is not associated with suicide risk. Overall, autistic people reported both positive and negative impacts of the pandemic on their lives.

Cultivating Self-Compassion to Improve Mental Health in Autistic Adults

Many autistic adults experience poor mental health. Research has consistently shown that cultivating self-compassion is a promising approach to strengthening resilience in nonautistic adults. Self-compassion is a trainable skill that is associated with several mental health benefits, such as higher levels of happiness and well-being as well as lower symptoms of depression and anxiety. However, no studies to date have explored self-compassion in autistic individuals. We suggest that self-compassion may be a relevant target in mental health interventions for autistic adults without severe or profound intellectual disability. Self-compassion may improve mental health in autistic adults through directly modifying emotions (as an emotion regulation strategy) or its interactions with emotion regulation processes. Existing approaches to cultivating self-compassion include identifying and practicing self-compassionate behaviors, using self-compassionate thought records, and practicing self-compassion meditations. Before self-compassion approaches are implemented by autistic adults, it will be necessary to evaluate their role and effectiveness in mental health through carefully designed studies. We suggest that researchers should first study the relationship between self-compassion and mental health outcomes in autistic adults. Once researchers have established the connection, we can then begin to study self-compassion-based interventions for autistic adults. Relevant clinical considerations include identifying the autistic groups that self-compassion practices are suitable for, determining how autistic adults with and without mental health conditions can effectively practice self-compassion (on their own and with the support of clinicians), and evaluating existing self-compassion tools or designing new tools. It is also relevant for future research to identify the enablers and barriers to using self-compassion in autistic adults.

Lay summary

What is self-compassion?: Self-compassion is when we: are friendly toward ourselves (kindness)are aware of our feelings and thoughts (mindful awareness)realize that everyone feels pain and makes mistakes (common humanity)What is the purpose of this article?: We think that practicing self-compassion is important for autistic adults. No research has studied self-compassion in autistic individuals. We provide examples of how to improve self-compassion. We make recommendations for future research on self-compassion for autistic adults.What perspectives do the authors bring to this subject?: We bring together different and unique perspectives in this article. One author is a researcher whose research has focused on emotion regulation and mental health in autistic youth and adults. The other author is a self-compassion researcher who is also a private practice clinical psychologist. We have practiced self-compassion and personally experienced the benefits of developing our self-compassion skills. We think that cultivating self-compassion has helped to improve our mental health and enriched our lives.Why is self-compassion important?: Self-compassion is associated with a lot of positive aspects of life in nonautistic individuals. These positive aspects include greater happiness and well-being, and lower levels of depression and anxiety symptoms.How is self-compassion relevant to autistic adults?: We know that as a group, autistic adults have poorer mental health when compared with nonautistic adults. That is, autistic adults experience higher rates of anxiety and depression. Research shows that practicing self-compassion in nonautistic people can improve their mental health. We think that cultivating self-compassion can also be helpful to autistic adults.What do the authors recommend?: We suggest that cultivating self-compassion may improve the mental health of autistic adults. There are several ways to improve self-compassion. Self-compassion can be improved by identifying and practicing self-compassionate behaviors. For example, we can take a walk outside. Another way to improve self-compassion is to record our thoughts. This can be performed by keeping a log of self-critical thoughts. We can also practice self-compassion by meditating. It is too early to tell how self-compassion should be practiced by autistic adults. Research is needed to observe if self-compassion is helpful to autistic adults. We made a series of recommendations for researchers and clinicians. Researchers should first check if there is a relationship between self-compassion and mental health in autistic adults. If more self-compassion is associated with better mental health, then researchers and clinicians can try and find out how we can improve autistic people's self-compassion.How will these recommendations help autistic adults now or in the future?: We hope that our recommendations will start a conversation on the relevance of self-compassion for autistic adults and lead to the development of self-compassion-related research programs that involve autistic adults. The ultimate goal is to improve the mental health and psychological well-being of autistic adults in the future.

Development and validation of the suicidal behaviours questionnaire - autism spectrum conditions in a community sample of autistic, possibly autistic and non-autistic adults

BACKGROUND

Autistic people and those with high autistic traits are at high risk of experiencing suicidality. Yet, there are no suicidality assessment tools developed or validated for these groups.

METHODS

A widely used and validated suicidality assessment tool developed for the general population (SBQ-R), was adapted using feedback from autistic adults, to create the Suicidal Behaviours Questionnaire-Autism Spectrum Conditions (SBQ-ASC). The adapted tool was refined through nine interviews, and an online survey with 251 autistic adults, to establish clarity and relevance of the items. Subsequently, 308 autistic, 113 possibly autistic, and 268 non-autistic adults completed the adapted tool online, alongside self-report measures of autistic traits (AQ), camouflaging autistic traits (CAT-Q), depression (PHQ-9), anxiety (ASA-A), thwarted belongingness and perceived burdensomeness (INQ-15), lifetime non-suicidal self-injury, and the original version of the suicidality assessment tool (SBQ-R). Analyses explored the appropriateness and measurement properties of the adapted tool between the groups.

RESULTS

There was evidence in support of content validity, structural validity, internal consistency, convergent and divergent validity, test-retest validity, sensitivity and specificity (for distinguishing those with or without lifetime experience of suicide attempt), and hypothesis testing of the adapted tool (SBQ-ASC) in each group. The structure of the SBQ-ASC was equivalent between autistic and possibly autistic adults, regardless of gender, or use of visual aids to help quantify abstract rating scales.

LIMITATIONS

The samples involved in the development and validation of the adapted tool were largely female, and largely diagnosed as autistic in adulthood, which limits the generalisability of results to the wider autistic population. The SBQ-ASC has been developed for use in research and is not recommended to assess risk of future suicide attempts and/or self-harm. The SBQ-ASC has been designed with and for autistic and possibly autistic adults, and is not appropriate to compare to non-autistic adults given measurement differences between these groups.

CONCLUSIONS

The SBQ-ASC is a brief self-report suicidality assessment tool, developed and validated with and for autistic adults, without co-occurring intellectual disability. The SBQ-ASC is appropriate for use in research to identify suicidal thoughts and behaviours in autistic and possibly autistic people, and model associations with risk and protective factors.
