Approaches to improving mental health care for autistic children and young people: a systematic review and meta-analysis.

Autistic children and young people (CYP) experience mental health difficulties but face many barriers to accessing and benefiting from mental health care. There is a need to explore strategies in mental health care for autistic CYP to guide clinical practice and future research and support their mental health needs. Our aim was to identify strategies used to improve mental health care for autistic CYP and examine evidence on their acceptability, feasibility, and effectiveness. A systematic review and meta-analysis were carried out. All study designs reporting acceptability/feasibility outcomes and empirical quantitative studies reporting effectiveness outcomes for strategies tested within mental health care were eligible. We conducted a narrative synthesis and separate meta-analyses by informant (self, parent, and clinician). Fifty-seven papers were included, with most investigating cognitive behavioral therapy (CBT)-based interventions for anxiety and several exploring service-level strategies, such as autism screening tools, clinician training, and adaptations regarding organization of services. Most papers described caregiver involvement in therapy and reported adaptations to communication and intervention content; a few reported environmental adjustments. In the meta-analyses, parent- and clinician-reported outcomes, but not self-reported outcomes, showed with moderate certainty that CBT for anxiety was an effective treatment compared to any comparison condition in reducing anxiety symptoms in autistic individuals. The certainty of evidence for effectiveness, synthesized narratively, ranged from low to moderate. Evidence for feasibility and acceptability tended to be positive. Many identified strategies are simple, reasonable adjustments that can be implemented in services to enhance mental health care for autistic individuals. Notable research gaps persist, however.

A Systematic Review of the Assessment of ICD-11 Complex Post-Traumatic Stress Disorder (CPTSD) in Young People and Adults.

Complex post-traumatic stress disorder (CPTSD) was introduced in the International Classification of Diseases (ICD) 11 in 2013 to simplify diagnosis and increase clinical utility. Given the recent ICD-11 conceptualisation, there is no standard approach for its assessment, and a review of research is necessary. This systematic review focuses on ICD-11 CPTSD assessment in young people aged 7 to 17 and adults aged 18 and above, examining measures, differentiating features and clinical considerations. Data from five databases are reviewed using a narrative synthesis approach and the quality of evidence is assessed and discussed. A total of 36 studies involving 5901 participants recruited from clinical settings and 1458 professionals with CPTSD assessment experience were included. Studies predominantly focused on adults, and the most used measure for assessment was the International Trauma Questionnaire. Papers focusing on differentiating features highlighted increased symptom severity, impairment and difficulties in individuals with CPTSD, compared to those with PTSD across various characteristics in both young people and adults. This review also identified the importance of a sensitive clinical approach with adaptations based on culture and age. Although gold-standard recommendations cannot be made, this paper offers tentative clinical practice recommendations and considerations regarding ICD-11 CPTSD assessment.

The prevalence of autism spectrum disorder traits and diagnosis in adults and young people with personality disorders: A systematic review.

OBJECTIVES: Autism spectrum disorders and personality disorders are spectrum conditions with shared clinical features. Despite similarities, previous attempts to synthesise literature on co-existing prevalence and shared traits have employed a unidirectional focus, assessing personality characteristics of individuals with an autism spectrum disorder diagnosis. Here, we assess the prevalence of autism spectrum disorder diagnosis and/or traits among persons diagnosed with a personality disorder. METHODS: We systematically reviewed the English-language literature following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, according to a pre-registered protocol (PROSPERO: CRD 42021264106). Peer-reviewed quantitative studies reporting the prevalence of autism spectrum disorder diagnosis or traits in persons with an established personality disorder diagnosis were included. Studies were critically appraised using the Appraisal tool for Cross-Sectional Studies. RESULTS: Fifteen studies were identified, including 72,902 participants (median: 48, interquartile range: 30-77). Diagnoses included borderline, schizotypal and obsessive-compulsive personality disorders, and cohorts with unspecified personality disorder diagnoses. There was significant heterogeneity in diagnostic methodology and assessment tools used. We identified preliminary evidence of an increased prevalence of co-existing autism spectrum disorder diagnosis and traits among those diagnosed with a personality disorder, although significant limitations of the literature were identified. CONCLUSION: Our research suggests clinicians should consider conducting a careful developmental assessment when assessing service-users with possible or confirmed personality disorder. Future research directions may include larger studies featuring clinical control groups, an exploration of shared and differentiating behavioural-cognitive features of the two conditions, and investigation into potentially shared aetiological factors. Research investigating demographic factors that may contribute to potential diagnostic overshadowing would also be welcomed.

Abnormal functional activation and maturation of ventromedial prefrontal cortex and cerebellum during temporal discounting in autism spectrum disorder.

People with autism spectrum disorder (ASD) have poor decision-making and temporal foresight. This may adversely impact on their everyday life, mental health, and productivity. However, the neural substrates underlying poor choice behavior in people with ASD, or its' neurofunctional development from childhood to adulthood, are unknown. Despite evidence of atypical structural brain development in ASD, investigation of functional brain maturation in people with ASD is lacking. This cross-sectional developmental fMRI study investigated the neural substrates underlying performance on a temporal discounting (TD) task in 38 healthy (11-35 years old) male adolescents and adults with ASD and 40 age, sex, and IQ-matched typically developing healthy controls. Most importantly, we assessed group differences in the neurofunctional maturation of TD across childhood and adulthood. Males with ASD had significantly poorer task performance and significantly lower brain activation in typical regions that mediate TD for delayed choices, in predominantly right hemispheric regions of ventrolateral/dorsolateral prefrontal cortices, ventromedial prefrontal cortex, striatolimbic regions, and cerebellum. Importantly, differential activation in ventromedial frontal cortex and cerebellum was associated with abnormal functional brain maturation; controls, in contrast to people with ASD, showed progressively increasing activation with increasing age in these regions; which furthermore was associated with performance measures and clinical ASD measures (stereotyped/restricted interests). Findings provide first cross-sectional evidence that reduced activation of TD mediating brain regions in people with ASD during TD is associated with abnormal functional brain development in these regions between childhood and adulthood, and this is related to poor task performance and clinical measures of ASD.

Psychological interventions for post-traumatic stress disorder (PTSD) in people with severe mental illness.

BACKGROUND: Increasing evidence indicates that individuals who develop severe mental illness (SMI) are also vulnerable to developing post-traumatic stress disorder (PTSD), due to increased risk of exposure to traumatic events and social adversity. The effectiveness of trauma-focused psychological interventions (TFPIs) for PTSD in the general population is well-established. TFPIs involve identifying and changing unhelpful beliefs about traumatic experiences, processing of traumatic memories, and developing new ways of responding to cues associated with trauma. Little is known about the potential feasibility, acceptability and effectiveness of TFPIs for individuals who have a SMI and PTSD. OBJECTIVES: To evaluate the effectiveness of psychological interventions for PTSD symptoms or other symptoms of psychological distress arising from trauma in people with SMI. SEARCH METHODS: We searched the Cochrane Schizophrenia Group's Trials Study-Based Register (up until March 10, 2016), screened reference lists of relevant reports and reviews, and contacted trial authors for unpublished and/or specific outcome data. SELECTION CRITERIA: We included all relevant randomised controlled trials (RCTs) which investigated TFPIs for people with SMI and PTSD, and reported useable data. DATA COLLECTION AND ANALYSIS: Three review authors (DS, MF, IN) independently screened the titles and abstracts of all references identified, and read short-listed full text papers. We assessed risk of bias in each case. We calculated the risk ratio (RR) and 95% confidence interval (CI) for binary outcomes, and the mean difference (MD) and 95% CI for continuous data, on an intention-to-treat basis. We assessed quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) and created 'Summary of findings' tables. MAIN RESULTS: Four trials involving a total of 300 adults with SMI and PTSD are included. These trials evaluated three active intervention therapies: trauma-focused cognitive behavioural therapy (TF-CBT), eye movement desensitisation and reprocessing (EMDR), and brief psychoeducation for PTSD, all delivered via individual sessions. Our main outcomes of interest were PTSD symptoms, quality of life/well-being, symptoms of co-morbid psychosis, anxiety symptoms, depressive symptoms, adverse events and health economic outcomes. 1. TF-CBT versus usual care/waiting list Three trials provided data for this comparison, however, continuous outcome data available were more often found to be skewed than unskewed, leading to the necessity of conducting analyses separately for the two types of continuous data. Using the unskewed data only, results showed no significant differences between TF-CBT and usual care in reducing clinician-rated PTSD symptoms at short term (1 RCT, n =13, MD 13.15, 95% CI -4.09 to 30.39,low-quality evidence). Limited unskewed data showed equivocal results between groups in terms of general quality of life (1 RCT, n = 39, MD -0.60, 95% CI -4.47 to 3.27, low-quality evidence), symptoms of psychosis (1 RCT, n = 9, MD -6.93, 95% CI -34.17 to 20.31, low-quality evidence), and anxiety (1 RCT, n = 9, MD 12.57, 95% CI -5.54 to 30.68, very low-quality evidence), at medium term. The only available data on depression symptoms were skewed and were equivocal across groups at medium term (2 RCTs, n = 48, MD 3.26, 95% CI -3.66 to 10.18, very low-quality evidence). TF-CBT was not associated with more adverse events (1 RCT, n = 100, RR 0.44, 95% CI 0.09 to 2.31, low-quality evidence) at medium term. No data were available for health economic outcomes. Very limited data for PTSD and other symptoms were available over the long term. 2. EMDR versus waiting listOne trial provided data for this comparison. Favourable effects were found for EMDR in terms of PTSD symptom severity at medium term but data were skewed (1 RCT, n = 83, MD -12.31, 95% CI -22.72 to -1.90, very low-quality evidence). EMDR was not associated with more adverse events (1 RCT, n = 102, RR 0.21, 95% CI 0.02 to 1.85, low-quality evidence). No data were available for quality of life, symptoms of co-morbid psychosis, depression, anxiety and health economics.3. TF-CBT versus EMDROne trial compared TF-CBT with EMDR. PTSD symptom severity, based on skewed data (1 RCT, n = 88, MD -1.69, 95% CI -12.63 to 9.23, very low-quality evidence) was similar between treatment groups. No data were available for the other main outcomes.4. TF-CBT versus psychoeducationOne trial compared TF-CBT with psychoeducation. Results were equivocal for PTSD symptom severity (1 RCT, n = 52, MD 0.23, 95% CI -14.66 to 15.12, low-quality evidence) and general quality of life (1 RCT, n = 49, MD 0.11, 95% CI -0.74 to 0.95, low-quality evidence) by medium term. No data were available for the other outcomes of interest. AUTHORS' CONCLUSIONS: Very few trials have investigated TFPIs for individuals with SMI and PTSD. Results from trials of TF-CBT are limited and inconclusive regarding its effectiveness on PTSD, or on psychotic symptoms or other symptoms of psychological distress. Only one trial evaluated EMDR and provided limited preliminary evidence favouring EMDR compared to waiting list. Comparing TF-CBT head-to-head with EMDR and brief psychoeducation respectively, showed no clear effect for either therapy. Both TF-CBT and EMDR do not appear to cause more (or less) adverse effects, compared to waiting list or usual care; these findings however, are mostly based on low to very low-quality evidence. Further larger scale trials are now needed to provide high-quality evidence to confirm or refute these preliminary findings, and to establish which intervention modalities and techniques are associated with improved outcomes, especially in the long term.

Family therapy for autism spectrum disorders.

BACKGROUND: Autism spectrum disorders (ASDs) are characterised by impairments in communication and reciprocal social interaction. These impairments can impact on relationships with family members, augment stress and frustration, and contribute to behaviours that can be described as challenging. Family members of individuals with ASD can experience high rates of carer stress and burden, and poor parental efficacy. While there is evidence to suggest that individuals with ASD and family members derive benefit from psychological interventions designed to reduce stress and mental health morbidity, and enhance coping, most studies to date have targeted the needs of either individuals with ASD, or family members. We wanted to examine whether family (systemic) therapy, aimed at enhancing communication, relationships or coping, is effective for individuals with ASD and their wider family network. OBJECTIVES: To evaluate the clinical effectiveness and acceptability of family therapy as a treatment to enhance communication or coping for individuals with ASD and their family members. If possible, we will also seek to establish the economic costs associated with family therapy for this clinical population. SEARCH METHODS: On 16 January 2017 we searched CENTRAL, MEDLINE, Embase, 10 other databases and three trials registers. We also handsearched reference lists of existing systematic reviews and contacted study authors in the field. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs investigating the effectiveness of family therapy for young people or adults with ASD or family members, or both, delivered via any modality and for an unspecified duration, compared with either standard care, a wait-list control, or an active intervention such as an alternative type of psychological therapy. DATA COLLECTION AND ANALYSIS: Two authors independently screened each title and abstract and all full-text reports retrieved. To enhance rigour, 25% of these were independently screened by a third author. MAIN RESULTS: The search yielded 4809 records. Of these, we retrieved 37 full-text reports for further scrutiny, which we subsequently excluded as they did not meet the review inclusion criteria, and identified one study awaiting classification. AUTHORS' CONCLUSIONS: Few studies have examined the effectiveness of family therapy for ASD, and none of these are RCTs. Further research studies employing methodologically robust trial designs are needed to establish whether family therapy interventions are clinically beneficial for enhancing communication, strengthening relationships, augmenting coping and reducing mental health morbidity for individuals with ASD and family members.

Microduplications at the pseudoautosomal SHOX locus in autism spectrum disorders and related neurodevelopmental conditions.

BACKGROUND: The pseudoautosomal short stature homeobox-containing (SHOX) gene encodes a homeodomain transcription factor involved in cell-cycle and growth regulation. SHOX/SHOX enhancers deletions cause short stature and skeletal abnormalities in a female-dominant fashion; duplications appear to be rare. Neurodevelopmental disorders (NDDs), such as autism spectrum disorders (ASDs), are complex disorders with high heritability and skewed sex ratio; several rare (<1% frequency) CNVs have been implicated in risk. METHODS: We analysed data from a discovery series of 90 adult ASD cases, who underwent clinical genetic testing by array-comparative genomic hybridisation (CGH). Twenty-seven individuals harboured CNV abnormalities, including two unrelated females with microduplications affecting SHOX. To determine the prevalence of SHOX duplications and delineate their associated phenotypic spectrum, we subsequently examined array-CGH data from a follow-up sample of 26 574 patients, including 18 857 with NDD (3541 with ASD). RESULTS: We found a significant enrichment of SHOX microduplications in the NDD cases (p=0.00036; OR 2.21) and, particularly, in those with ASD (p=9.18×10(-7); OR 3.63) compared with 12 594 population-based controls. SHOX duplications affecting the upstream or downstream enhancers were enriched only in females with NDD (p=0.0043; OR 2.69/p=0.00020; OR 7.20), but not in males (p=0.404; OR 1.38/p=0.096; OR 2.21). CONCLUSIONS: Microduplications at the SHOX locus are a low penetrance risk factor for ASD/NDD, with increased risk in both sexes. However, a concomitant duplication of SHOX enhancers may be required to trigger a NDD in females. Since specific SHOX isoforms are exclusively expressed in the developing foetal brain, this may reflect the pathogenic effect of altered SHOX protein dosage on neurodevelopment.

What factors influence successful recruitment of siblings of individuals with first episode psychosis to e-health interventions? A qualitative study.

BACKGROUND: Recruitment to clinical research studies can prove complex. This is particularly true of mental health research, given factors such as confidentiality, capacity and consent, or when attempting to recruit family members as opposed to service users themselves. AIM: This study investigated the challenges experienced and strategies employed in the recruitment of siblings of people with first episode psychosis using Early Intervention in Psychosis Services (EIPS) in England. METHODS: As part of a randomized controlled trial (RCT) of an e-health intervention for siblings, we conducted a process evaluation study whereby semistructured interview was undertaken with clinical and research staff involved in recruitment of siblings. Data were analysed thematically. RESULTS: Twelve participants from six EIPS were interviewed. Data analysis revealed seven key themes: (i) limited comprehensive family data available; (ii) data governance and consent issues; (iii) organizational factors; (iv) convoluted recruitment methods; (v) concerns about service users' opinions; (vi) fluidity in siblings' needs and expectations; and (vii) strategies to enhance recruitment. CONCLUSIONS: Recruitment challenges identified in this study concerned administrative, organizational, process and attitudinal issues. These are similar to other studies recruiting mental health service users as well as family members. Failure to recruit to target implies that studies are underpowered to detect potential statistically or clinically meaningful changes. Future studies should establish how best to enhance family inclusiveness in clinical practice and research.

Conceptualizing and Treating Social Anxiety in Autism Spectrum Disorder: A Focus Group Study with Multidisciplinary Professionals.

BACKGROUND: Individuals who have autism spectrum disorders (ASD) commonly experience social anxiety (SA). Disentangling SA symptoms from core ASD characteristics is complex, partly due to diagnostic overshadowing and co-occurring alexithymia. Causal and maintaining mechanisms for SA in ASD are underexplored, but it is feasible that there is an ASD specificity to the clinical presentation, with implications for the development of targeted treatments. METHODS: Five focus groups were conducted with multidisciplinary professionals to investigate their perspectives about, and approaches to, working with individuals with ASD and SA. Data were analysed thematically. RESULTS: Data analysis revealed two overarching themes: conceptualizing SA in ASD and service provision. Our results suggest that adaptations to service provision are pertinent, so as to accommodate inherent impairments that can mediate assessment and intervention. CONCLUSIONS: Future studies should establish how aspects of the care pathway can be improved for individuals with ASD and SA.

Wellbeing, mental health knowledge and caregiving experiences of siblings of people with psychosis, compared to their peers and parents: an exploratory study.

PURPOSE: The wellbeing and caregiving experiences of family carers supporting people with psychosis has garnered increasing interest. Evidence indicates that the burden of caregiving can adversely impact on parents' wellbeing, few studies have investigated whether this is also the case for siblings, who often take on caregiving responsibilities. This exploratory study investigated the wellbeing, mental health knowledge, and appraisals of caregiving in siblings of individuals with psychosis. METHOD: Using a cross-sectional design, 90 siblings completed three validated questionnaires: Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS), Mental Health Knowledge Schedule (MAKS), and Experience of Caregiving Inventory (ECI). Data obtained were compared to general population norms and parent-carers' scores. Multi-variable regression analyses were conducted to examine relationships between questionnaire scores and demographic characteristics including age, sex, birth order, marital status, accommodation and educational level. RESULTS: Siblings, especially sisters, had significantly poorer mental wellbeing, compared to normative scores. Conversely, they had better mental health knowledge. Siblings and parent-carers had comparable high levels of negative appraisals of caregiving experiences, but siblings reported more satisfaction with personal experiences and relationships. Education level was a significant predictor for better mental health knowledge; there were no other relationships between siblings' demographic factors and outcomes. CONCLUSION: Study findings suggest that siblings have overlapping as well as distinct needs, compared to parent-carers. Further research is required to better understand siblings' experiences so as to inform development of targeted interventions that enhance wellbeing and caregiving capacity.

Response inhibition and serotonin in autism: a functional MRI study using acute tryptophan depletion.

It has been suggested that the restricted, stereotyped and repetitive behaviours typically found in autism are underpinned by deficits of inhibitory control. The biological basis of this is unknown but may include differences in the modulatory role of neurotransmitters, such as serotonin, which are implicated in the condition. However, this has never been tested directly. We therefore assessed the modifying role of serotonin on inhibitory brain function during a Go/No-Go task in 14 adults with autism and normal intelligence and 14 control subjects that did not differ in gender, age and intelligence. We undertook a double-blind, placebo-controlled, crossover trial of acute tryptophan depletion using functional magnetic resonance imaging. Following sham, adults with autism relative to controls had reduced activation in key inhibitory regions of inferior frontal cortex and thalamus, but increased activation of caudate and cerebellum. However, brain activation was modulated in opposite ways by depletion in each group. Within autistic individuals depletion upregulated fronto-thalamic activations and downregulated striato-cerebellar activations toward control sham levels, completely 'normalizing' the fronto-cerebellar dysfunctions. The opposite pattern occurred in controls. Moreover, the severity of autism was related to the degree of differential modulation by depletion within frontal, striatal and thalamic regions. Our findings demonstrate that individuals with autism have abnormal inhibitory networks, and that serotonin has a differential, opposite, effect on them in adults with and without autism. Together these factors may partially explain the severity of autistic behaviours and/or provide a novel (tractable) treatment target.

Implementing 'Transforming Care' - The first two years of a pilot service for autistic adults experiencing mental health crisis warranting psychiatric admission.

BACKGROUND: Autistic adults are at increased risk of mental health difficulties; however Adult Mental Health Services (AMHS) often struggle to offer appropriate support to this group. Within England, Government initiatives, such as the 'Transforming Care' programme which included 'Building the Right Support' (NHS England, 2015) have promoted the need for AMHS to consider how they can better provide autism-informed support to autistic adults. AIMS/METHODS: Here, we describe the first two years of work of the Transforming Care in Autism (TCA) Team; a specialist service that supports autistic adults, without a moderate or severe intellectual disability or presenting significant risk to others, experiencing a mental health crisis. The service model is described, and descriptive data is presented over the two years of the service operation. RESULTS: Between February 2019 and February 2021, 110 referrals were received; 52 (47%) were accepted. Support offered to autistic adults included psychoeducation, psychological interventions, family-focused interventions, and consultation with professionals about specific individuals. Seventy autism training sessions were delivered to professionals working in medical health settings, AMHS, social care and residential services. CONCLUSIONS/IMPLICATIONS: Developing more autism-informed community and inpatient AMHS is vital for improving care. Further research about the experiences and needs of autistic adults using AMHS is needed, along with improved awareness of autism and provision of tailored intervention within these settings. LAY ABSTRACT: Autistic people have mental health problems more often than people who are not autistic. When autistic people need help from mental health services, often these services do not know how to help autistic people. The Government says mental health services must do more to help autistic people. In this paper we write about a new team, called the Transforming Care in Autism team. In its first two years the team was asked to help 110 people and worked with 52 of them. Help included talking to autistic people about how autism affects them and offering therapy. We also worked with families and professionals supporting autistic adults and offered 70 training sessions. More work is needed to make sure mental health services work well with autistic people. We also need to ask autistic people about their experiences of getting help from mental health services.

Using EMDR with autistic individuals: A Delphi survey with EMDR therapists.

LAY ABSTRACT: Eye Movement Desensitisation and Reprocessing (EMDR) is a psychological therapy that can help people process memories and distress about past events, so they have less impact on their daily lives. EMDR can be effective for treating symptoms of post-traumatic stress disorder, including nightmares and anxiety. Psychological therapies usually require adaptation so they are more accessible and effective for autistic people, but minimal research has focused on how best EMDR can be adapted. In this online survey study, we asked 103 EMDR therapists about barriers they think autistic people face when trying to have EMDR and what adaptations they use in their everyday practice. Four barriers were highlighted: client-related characteristics, therapist-related characteristics, differences in the therapeutic relationship and broader issues. Therapists identified a range of adaptations that can potentially be useful for autistic people, relating to being flexible, communicating clearly and having an awareness of individual differences. Many therapists emphasised the importance of not making assumptions about a person based on their autism diagnosis. Overall, the study findings suggest adaptations to EMDR are likely to be useful, but how relevant they are depends on each person.

Compassion-focused therapy with autistic adults.

Some autistic adults experience repeated adverse events, including rejection, victimization and stigmatization. They also describe others being critical and negatively judging them, such as for how they socially interact or for expressing passion for particular interests. The impact of these adverse events can be substantial, including increasing vulnerability for poorer mental health, and contributing to development of negative self beliefs (such as "I am different" or "I do not fit in") and shame-based difficulties. Not all evidence-based psychological therapies are well-received by autistic people, or effective. Given high rates of self-harm and suicidality, finding acceptable and effective therapies for autistic adults is paramount. Here, writing as autistic and non-autistic clinicians and researchers, we outline the theoretical principles of compassion-focused theory and therapy (CFT). We propose that: (1) compassion-focused theory can provide a useful framework for conceptualizing shame-based difficulties some autistic adults experience; (2) CFT can be appropriate for addressing these; and (3) there is an impetus for practitioners to adopt compassion-focused approaches when supporting autistic adults.

Alexithymia in Adult Autism Clinic Service-Users: Relationships with Sensory Processing Differences and Mental Health.

Mental health difficulties commonly co-occur with autism, especially in autistic people accessing clinic services, impacting substantially on quality-of-life. Alexithymia (difficulty describing/identifying feelings) and sensory processing differences are prevalent traits in autism that have been associated with depression/anxiety in autistic community samples. However, it is important to better understand interrelationships between these traits in clinical populations to improve identification of service-user needs. In this study, 190 autistic adults (65.3% male), seen in a tertiary autism clinic, completed self-report measures of alexithymia (20-item Toronto Alexithymia Scale), sensory processing differences (Adolescent/Adult Sensory Profile) and depression/anxiety (Hospital Anxiety and Depression Scale). Multiple linear regression models and mediation analyses were used to examine associations between alexithymia, sensory processing differences, and depression/anxiety severity. Across the sample, 66.3% of individuals (N = 126) were classified as alexithymic (score ≥ 61). Total alexithymia and difficulty describing/identifying feelings were significantly associated with depression severity (ß = 0.30-0.38, highest p < 0.002), and difficulty identifying feelings was significantly associated with anxiety severity (ß = 0.36, p < 0.001). Sensory processing differences were also significantly associated with depression severity (ß = 0.29, p = 0.002) and anxiety severity across all models (ß = 0.34-0.48, highest p < 0.001) Finally, difficulty describing/identifying feelings partially mediated the relationships between sensory processing differences and both depression/anxiety severity. Overall, these results highlight that interventions adapted for and targeting emotional awareness and sensory-related uncertainty may improve mental health outcomes in autistic service-users.

Impact of the COVID-19 Pandemic on Daily Life: Diverse Experiences for Autistic Adults.

Using a mixed methods design, this study aimed to examine the impact of the COVID-19 pandemic on autistic and non-autistic adults. We conducted an online survey with 196 autistic and 228 non-autistic adults from Belgium, the Netherlands and the United Kingdom focusing on their experiences during the first period of the pandemic. Our results indicate rather diverse experiences within the group of autistic participants across all domains of life. In comparison with non-autistic adults, autistic adults reported less negative impact on their social life and more negative impact on health and support services. In the autism group, stress was mainly related to changing and unclear measures. A wide range of coping strategies were described as helpful in reducing stress during the pandemic.

Mental health of autistic adults during the COVID-19 pandemic: The impact of perceived stress, intolerance of uncertainty, and coping style.

LAY ABSTRACT: More and more research shows us that autistic individuals are at risk of experiencing mental health problems in response to the COVID-19 pandemic. However, little is known about why this is the case. At two timepoints during the pandemic, we asked 149 autistic and 147 non-autistic adults about feelings of anxiety, depression, and stress, and about characteristics that may explain why some (autistic) people have a larger chance of developing anxiety and depression during this pandemic. In our study, autistic adults experienced more anxiety and depression than non-autistic adults. Across autistic and non-autistic individuals, the people who experienced more stress at timepoint 1 experienced more anxiety and depression 4 months later. This was especially the case for those individuals who use maladaptive coping styles, such as denial or venting, and for those who have difficulties dealing with uncertain situations. Our findings show the burden of the COVID-19 pandemic on the mental health of autistic adults. Interventions to support autistic adults during and after the pandemic are needed, and they may want to focus on the negative impact of stress and teach autistic (and non-autistic) adults more adaptive ways to cope with stressful circumstances.

Improving Cognitive Behaviour Therapy for Autistic Individuals: A Delphi Survey with Practitioners.

There is emerging evidence of the effectiveness of individual and group cognitive behaviour therapy (CBT) for autistic individuals, in particular to address anxiety, obsessive compulsive disorder and depression. Many CBT studies have incorporated relatively stringent standards, with regards to participant inclusion/exclusion criteria, delivery of manualised approaches and assurance of therapist training and oversight. We know less about what happens in routine CBT practice and, importantly, how service provision can be improved for autistic individuals. The present study recruited 50 CBT practitioners to a three round Delphi survey. The aims were to elicit professionals' perspectives regarding barriers to the acceptability and effectiveness of CBT for autistic individuals, and to generate consensus, both about ways of enhancing service provision, as well as the autism-relevant training needs of CBT practitioners. Study findings indicated six barriers to accessible and effective CBT for autistic individuals, relating to service provision, practitioner-related factors, client-related factors, CBT-related factors, national guidelines, and systemic considerations. There was participant consensus that changes in five domains (specifically relating to process issues, service provision, practitioners, techniques and therapeutic approach) could improve the CBT care pathway. Consensus was generated about the training needs of CBT practitioners: training about autism, CBT-specific issues, co-occurring conditions and engagement, were deemed fundamental for enhancing practice. Participants also identified autism-relevant issues for clinical supervision. Further sustained research is needed to determine the effects of adapted service provision and improved practitioner knowledge and skills on the outcomes of autistic individuals who have CBT.

Using eye movement desensitisation and reprocessing (EMDR) with autistic individuals: A qualitative interview study with EMDR therapists.

OBJECTIVES: Eye Movement Desensitisation and Reprocessing (EMDR) is an evidence-based psychological therapy that targets distress associated with trauma and affective disturbance. Few studies have examined EMDR for autistic individuals who have co-occurring mental health conditions, but there is preliminary evidence of effectiveness. The current study explored EMDR therapists' experiences of working with autistic individuals, and adaptations incorporated into clinical practice to make this more accessible and effective. DESIGN: A qualitative interview design was used. Data were thematically analysed. METHOD: Twenty-three UK-based EMDR therapists attended one-off semi-structured qualitative interviews. RESULTS: Four main themes emerged: (1) the experience of being autistic; (2) factors around accessing EMDR; (3) adapting EMDR; and (4) supervision and support for EMDR therapists. Participants described offering a nuanced and tailored approach; one that retained the integral components of the eight phases of EMDR, while also being flexible and responsive to each client. CONCLUSIONS: Findings reinforce the importance of offering formulation-based psychological therapy that flexes in an evidence-informed way, according to the preferences and needs of autistic individuals. Further research should establish factors influencing accessibility and effectiveness of EMDR for autistic individuals, and the impact of autism-relevant training on the knowledge, skills and confidence of EMDR therapists and clinical supervisors working with this client group.

Aging and autism: Do measures of autism symptoms, co-occurring mental health conditions, or quality of life differ between younger and older autistic adults?

Previous research has indicated that autistic adults experience higher rates of co-occurring mental health difficulties and poorer quality of life (QoL) than their non-autistic peers. Little is known, however, about these aspects in older age or whether younger and older autistic adults experience similar patterns This cross-sectional study investigated potential age-related effects on autism symptoms, self-reported mental health, and QoL in younger and older autistic adults (n = 79, aged 19-71 years) compared to a non-autistic control group (n = 57) matched for gender, age and IQ. Results showed that autistic adults had higher levels of self-reported autism symptoms and poorer QoL than controls. There were no significant age effects on autism symptoms or on most self-rated mental health symptoms. However, significantly more autistic adults in the younger versus older group scored above the clinical threshold for anxiety, somatoform disorders and eating disorders. Older autistic adults rated social QoL as significantly better than younger autistic adults; there was no significant age difference in the control group. Self-reported QoL was best predicted by self-ratings of severity of depressive symptoms in both groups. Further research is needed to track autism and co-occurring mental health symptomatology across the lifespan, so that service provision can be tailored accordingly. LAY SUMMARY: Young autistic adults have reported more psychological difficulties and poorer quality of life (QoL) than the general population. We investigated whether these difficulties continue into older age. Autism symptoms and mental health problems were common in autistic adults, with no difference between age groups, except for anxiety, physical and eating problems. Although QoL was poorer in both younger and older autistic compared to non-autistic adults, older autistic adults reported better social QoL than those who were younger.
