Development of the Impact of Diagnosis Scale-Revised (IODS-R)

No tools quantify the experience, psychological, and practical impact of receiving a diagnosis from a non-deficit perspective. Autism is increasingly late diagnosed in adulthood. The Impact of Diagnosis Scale (IODS) was initially developed for borderline personality disorder. We aimed to develop a revised version suitable for autistic adults and potentially other diagnostic groups. Following a trial of a preliminary revision, the researchers and autistic research advisors co-produced an expanded pool of 46 items, scored on 7-point Likert-type scale, within 6 hypothesized domains. Scale reduction processes were applied to data from 125 formally diagnosed autistic adults. Following iterative rounds of factor analysis using maximum likelihood estimation with Promax rotation, 22 items were retained across 4 domains to comprise the IODS-R. The IODS-R adds new understanding to the experience of receiving an autism diagnosis in adulthood. It may be useful for evaluating diagnostic services and other diagnostic groups.

A Qualitative Study of Adults' and Support Persons' Experiences of Support After Autism Diagnosis

Adulthood autism diagnosis has become increasingly common, but little is known about post-diagnosis support experiences and needs. We interviewed 19 autistic adults and 4 support persons on experiences of formal and informal post-diagnosis support. Reflexive thematic analysis was used to identify themes. Participants reported difficulties accessing suitable formal support, especially regarding education and employment. Informal support was helpful but created challenges in the relationships between autistic adults and support persons. For autistic adults, support from autistic peers fostered belonging and self-acceptance. We also identified complex interactions between adults' post-diagnosis identity development and support experiences as they resolved the dilemma between self-acceptance and a desire to change. Findings have important implications for services working with autistic adults and their families.

Experiences of Support Following Autism Diagnosis in Adulthood

This study aimed to explore experiences of support after adulthood autism diagnosis. In this mixed-methods survey study of 137 adults, we found that most common formal supports received were counselling and mental health. Common unmet support needs were sensory sensitivities and accessing other services. Cost, lack of information, and fear of not being taken seriously were common barriers. Informal support was mainly helpful for self-understanding and emotions toward diagnosis. Qualitative findings included difficulties accessing formal support, need for practical quality-of-life supports and support from autistic peers and online communities. Based on these findings, future development of supportive interventions should address unmet needs, improve access, and explore the integration of autistic peer support and online support into formal services.

Brief Report: Longitudinal Role of Coping Strategies on Mental Health Outcomes in Autistic Youth and Adults

The stress literature suggests that coping strategies are implicated in mental health outcomes. However, the longitudinal relationship between coping strategies and mental health in the autistic adult population has not yet been examined. This 2-year longitudinal study examined the predictive role of both baseline and change in coping strategy use over time (i.e., an increase or decrease) on anxiety, depression, and well-being after 2-years in 87 autistic adults aged 16 to 80 years. Controlling for baseline mental health, both baseline and increase in disengagement coping strategies (e.g., denial, self-blame) predicted higher anxiety and depression, and lower well-being, while an increase in engagement coping strategies (e.g., problem solving, acceptance) predicted higher well-being. These findings extend the current coping literature in autistic adults, offering insight into mental health support and intervention options.

Associations between coping strategies and mental health outcomes in autistic adults

Compared to the general population, mental health difficulties are commonly reported in autistic adults. However, the ways in which coping strategies are associated with mental health and well-being in this population remain unknown. Further, we do not know if, and if so, how these associations might differ to that of non-autistic adults. In this study, we hypothesized that in both our autistic (N = 255) and non-autistic (N = 165) adult samples, disengagement coping strategies (e.g., denial) would relate to poorer mental health and well-being, while engagement coping strategies (e.g., problem solving) would relate to better mental health and well-being. Regression analyses revealed that higher use of disengagement coping strategies was significantly associated with higher levels of anxiety and depression, and lower levels of well-being in both samples. In contrast, increased use of engagement coping strategies was associated with better well-being, but only in the autistic sample. Our results contribute to the characterization of negative and positive mental health outcomes in autistic adults from a coping perspective, with potential to offer novel information regarding coping strategies to consider when addressing support options for mental health difficulties in the autistic adult population.

Autistic Adults' Experiences of Diagnosis Disclosure

As autism is an invisible and often stigmatised condition, disclosing the diagnosis may lead to both support and/or discrimination. This mixed-methods questionnaire study examined autistic adults' experiences of disclosure in various contexts. The sample consisted of 393 participants aged 17-83 years from two longitudinal surveys. Almost all participants disclosed their diagnosis to someone, most commonly to friends. A significant minority of participants studying and/or working at the time had not disclosed to their education provider/employer. Content analysis of open-ended responses showed participants desired to gain understanding and support from disclosure but feared prejudice. While some received support, others encountered dismissiveness and misunderstanding. Findings highlight the need to improve autism understanding and reduce stigma within and beyond educational and employment contexts.

Factors associated with age at autism diagnosis in a community sample of Australian adults

Autism diagnosis in adulthood has become increasingly common due to a range of factors including changes in awareness, diagnostic criteria, and professional practices. Past research identified a range of demographic and autism-related factors associated with autism diagnosis age in children. However, it is unclear whether these apply to autistic adults. This study aimed to examine predictors of autism diagnosis age in adults while controlling for current age and autistic traits. We used a cross-sectional sample of 657 adults aged 15-80 from three self and carer-report studies: the Australian Longitudinal Study of Autism in Adulthood (ALSAA), Study of Australian School-Leavers with Autism (SASLA) and Pathways, Predictors and Impact of Receiving an Autism Spectrum Diagnosis in Adulthood (Pathways). Using hierarchical multiplicative heteroscedastic regression, we found that older current age and higher self-reported autistic traits predicted older diagnosis age, and that female gender, lack of intellectual disability, language other than English, family history of autism, lifetime depression, and no obsessive-compulsive disorder predicted older diagnosis age beyond current age and autistic traits. The paradoxical relationship between high autistic traits and older diagnosis age requires further investigation. Based on these findings, we recommended strategies to improve autism recognition in women and people from non-English-speaking backgrounds. Future studies could extend the findings by examining the effects of childhood and adulthood socioeconomic status on adult diagnosis age.

Employment profiles of autistic adults in Australia

Autistic adults experience a high number of job changes, reduced working hours, minimal workplace supports, and overrepresentation in entry-level and low paid positions. This study adds to the existing evidence base to guide clinical decisions and interventions for this population. This study utilized baseline data collected between 2015 and 2017 from the Autism CRC's Australian Longitudinal Study of Autism in Adulthood. The aim was to describe the employment profiles and explore factors related to employment for Australian autistic adults aged 25 and older (N = 149). Comparisons between participants and the Australian workforce were made using Australian Bureau of Statistics (ABS) data. Two logistic regression models were conducted to explore the association between underemployment and underutilisation with personal and environmental factors. In comparison to the Australian workforce, autistic adults were more likely to work part-time, work reduced hours and be employed at skill levels lower than their qualifications warranted. Logistic regressions reported that more autistic traits, more social supports and having workplace adjustments implemented were significantly associated with a higher odds of autistic adults being appropriately employed and/or utilized in the workforce. Results suggest that interventions implementing appropriate workplace adjustments, a supportive workplace environment, and adequate social supports may improve employment outcomes for autistic adults. All employees may benefit from workplace resources targeted toward fostering an inclusive workplace environment. LAY SUMMARY: This study aimed to describe the employment profiles and explore factors related to employment for Australian autistic adults. We compared this with the Australian workforce using data from the Australian Bureau of Statistics. Autistic adults with more autistic traits and more social and workplace supports were more likely to be employed and have jobs that were better suited to them. Autistic adults might have better employment outcomes if they have the appropriate workplace adjustments, a supportive workplace and adequate social supports.

Predictors of the Quality of Life of Informal Carers of Adults on the Autism Spectrum

Carers of adults on the autism spectrum often experience high levels of stress, worry, and caregiver burden. There are few studies identifying the predictors of carer mental well-being and none have been conducted in Australia. Data from the Autism Cooperative Research Centre for Living with Autism's Australian Longitudinal Study of Autism in Adulthood was used to test the conceptual model by Sonido et al. (Rev J Autism Dev Disord, 2019, https://doi.org/10.1007/s40489-019-00177-8 ) by (a) identifying the predictors of mental well-being for carers of adults on the spectrum, (b) using model selection to determine which predictors contribute to the model of best fit, and (c) testing for mediating relationships between the predictors. Several predictors were directly associated with carer psychological quality of life, including carer age, care recipient intellectual disability, and carer intolerance of uncertainty. Model selection strongly supported the inclusion of most clusters from the conceptual model. Some mediating relationships were found, such as care recipient depressive behaviours mediating the relationships between caregiver burden and psychological quality of life. Future studies of the conceptual model will improve understanding of the predictors of carer mental well-being and enable tailored interventions to improve the psychological health of carers of adults on the autism spectrum.

Choose your Own Adventure: Pathways to Adulthood Autism Diagnosis in Australia

Pathways to diagnosis in adulthood are poorly understood. Even less is known about undiagnosed adults who believe they may be autistic. This mixed-methods online survey examined adults' journeys from initial concern to receiving the diagnosis. Quantitative findings showed the diagnostic process to be highly heterogeneous. Qualitative analysis identified desires for explanation and support as motives for seeking diagnosis. Cost and fear of not being taken seriously were major barriers, echoed by qualitative responses that described the process as confusing, expensive and time-consuming. While most participants were satisfied with the diagnosis, their emotional reactions were complex. Findings support the need for thoroughly implementing national guidelines, and for improved knowledge and communication in mainstream clinicians encountering clients with possible autism characteristics.

Inter-relationships between trait resilience, coping strategies, and mental health outcomes in autistic adults

Resilience has been depicted as a key characteristic in the promotion of mental health in the face of stress and adversity. Despite high levels of stress encountered in the autistic population, resilience studies remain scarce. Using data from an Australian longitudinal adult study, this study explored the inter-relationships between trait resilience, coping, and mental health in a sample of autistic adults (N = 78). In particular, we examined the relationship between resilience and use of coping strategies, and the potential mediating role of coping strategies in the relationship between resilience and mental health outcomes. Our findings suggested that increased use of engagement coping (e.g., problem-solving, positive appraisal) and decreased use of disengagement coping (e.g., self-blame, being in denial) strategies were associated with higher levels of resilience. Further, mediation analysis results suggest that disengagement coping mediated the associations between resilience and all three mental health outcomes (i.e., depression, anxiety, and well-being), while engagement coping strategies mediated the relationship between resilience and well-being only. Our results illustrate that coping strategies may be an important mechanism in explaining the resilience-mental health relationship in autistic adults, highlighting the importance of considering stress-related constructs together (i.e., trait resilience and coping) when addressing support and intervention options for mental health difficulties in the autistic adult population. LAY SUMMARY: This research explored how resilience and coping strategies influence the mental health and well-being of autistic adults. We found that resilient autistic adults used more engagement coping strategies, less disengagement coping strategies, and reported better mental health and well-being. Considering stress-related factors together (i.e., resilience and coping) offers a novel perspective to mental health difficulties in autistic adults and may be a vital step in the development of support options in this population.

Neuropsychiatric profile and psychotropic medication use in adults with autism spectrum disorder: results from the Australian Longitudinal Study of Adults with Autism

BACKGROUND

Children and adolescents with autism spectrum disorder (ASD) are a highly medicated group. Few studies have examined the neuropsychiatric profile and patterns of psychotropic medication use among adults with ASD.

AIMS

To describe and compare the neuropsychiatric profile and psychotropic medication use in a cohort of adults with ASD and non-autistic controls.

METHOD

Baseline data from a survey-based, longitudinal study of adults with ASD in Australia. Participants were 188 adults with ASD and 115 controls aged 25-80 years.

RESULTS

ASD was associated with increased odds of psychotropic medication use even when controlling for the presence of any neurological or psychiatric disorder. There were no corresponding indications for 14.4% of psychotropic medications prescribed to adults with ASD.

CONCLUSIONS

This study found substantial psychotropic prescribing for adults with ASD. Patterns of psychotropic medication use may reflect prescribing for behavioural indications despite limited evidence to support this practice.

Does a Measure of Support Needs Predict Funding Need Better Than a Measure of Adaptive and Maladaptive Behavior?

Internationally, various approaches are used for the allocation of individualized funding. When using a databased approach, a key question is the predictive validity of adaptive behavior versus support needs assessment. This article reports on a subset of data from a larger project that allowed for a comparison of support needs and adaptive behavior assessments when predicting person-centered funding allocation. The first phase of the project involved a trial of the Inventory for Client and Agency Planning (ICAP) adaptive behavior and Instrument for the Classification and Assessment of Support Needs (I-CAN)-Brief Research version support needs assessments. Participants were in receipt of an individual support package allocated using a person-centered planning process, and were stable in their support arrangements. Regression analysis showed that the most useful items in predicting funding allocation came from the I-CAN-Brief Research. No additional variance could be explained by adding the ICAP, or using the ICAP alone. A further unique approach of including only items from the I-CAN-Brief Research marked as funded supports showed high predictive validity. It appears support need is more effective at determining resource need than adaptive behavior.

I-CAN: the classification and prediction of support needs

BACKGROUND

Since 1992, the diagnosis and classification of intellectual disability has been dependent upon three constructs: intelligence, adaptive behaviour and support needs (Luckasson et al. 1992. Mental Retardation: Definition, Classification and Systems of Support. American Association on Intellectual and Developmental Disability, Washington, DC). While the methods and instruments to measure intelligence and adaptive behaviour are well established and generally accepted, the measurement and classification of support needs is still in its infancy. This article explores the measurement and classification of support needs.

METHOD

A study is presented comparing scores on the ICF (WHO, 2001) based I-CAN v4.2 support needs assessment and planning tool with expert clinical judgment using a proposed classification of support needs. A logical classification algorithm was developed and validated on a separate sample.

RESULTS

Good internal consistency (range 0.73-0.91, N = 186) and criterion validity (κ = 0.94, n = 49) were found.

CONCLUSIONS

Further advances in our understanding and measurement of support needs could change the way we assess, describe and classify disability.

Intelligence is as intelligence does: can additional support needs replace disability?

Abstract In many developed cultures there is an assumption that IQ is intelligence. However, emerging theories of multiple intelligences, of emotional intelligence, as well as the application of IQ testing to other cultural groups, and to people with disability, raises many questions as to what IQ actually measures. Despite recent research that shows IQ testing produces a floor effect when applied to people with lower IQ, as well as research that shows the Flynn effect also applies to people with lower IQ, in practice IQ scores below a certain cut-off are still being used to determine and classify a person's intellectual disability. However, a new paradigm is emerging, almost returning to the original intent of Binet, where measurement is made of the supports the person needs. In this paper, we argue that if one extends the notions of this supports paradigm that diagnosis of intellectual or physical disability could potentially be replaced by diagnosis of additional intellectual support needs, or additional physical support needs.
