There has been longstanding speculation that enhanced creativity is associated with autism. Evidence for this association, however, is limited and derived from small-scale studies in nonclinical samples. Furthermore, nothing is known about autism-related creativity after accounting for general cognitive ability and attention-deficit/hyperactivity disorder (ADHD), that is, other factors known to predict creativity. Addressing these issues, we conducted preregistered comparisons of the creativity of autistic and nonautistic adults (N = 352), matched on age, sex, and general cognitive ability. We found clear evidence that there were no group differences on a divergent thinking creativity task. Autistic adults did self-report more real-world creative accomplishments and behaviors, but these differences did not hold after accounting for ADHD. We conclude that enhanced creativity, where observed in autistic people, is likely to be driven by co-occurring ADHD. The clinical and practical implications of these findings for strength-based approaches to psychopathology are discussed.

Strengths-based approaches to autism are increasing in research and clinical practice. Such approaches suggest facilitating autistic people to increase the use of their strengths leads to positive outcomes (e.g. improved well-being). However, despite proliferation of strengths-based clinical and educational interventions, these approaches are grounded on several assumptions that remain uninvestigated. Little is known about the specific strengths of autistic people, nor their current knowledge and use of their strengths. Critically, no research has directly tested if autistic people’s strengths knowledge and use is in fact associated with positive outcomes. Conducting an exploratory study, including the first well-powered comparisons of the self-reported strengths, strengths knowledge, and strengths use of matched autistic and non-autistic samples (N = 276), we found that autistic and non-autistic participants reported similar strengths. While autistic people reported lower strengths knowledge and use, strengths use in autism strongly predicted better quality of life, subjective well-being, and lower levels of anxiety, depression, and stress. Thus, strength-based approaches and clinical interventions designed to increase strengths use may pose a valuable method for boosting well-being in autism. However, we suggest such approaches should focus on individuals’ strengths more generally, rather than perceived autism-specific abilities. Lay abstract It is often suggested that supporting autistic people to identify and use their strengths will lead to positive outcomes. However, little research has explored if this is true. To date, no research has explored whether autistic people already have knowledge of and use their strengths, nor whether increased strengths knowledge and use is linked to good outcomes, such as a better quality of life, well-being and improved mental health. Comparing large samples of autistic and non-autistic people, this study tested these unanswered questions. We found that autistic and non-autistic people reported similar strengths, but autistic people reported less knowledge and use of their strengths compared to non-autistic people. Importantly however, autistic people who reported using their strengths often had better quality of life, well-being and mental health than autistic people who reported using their strengths less frequently. We, therefore, propose that supporting autistic people to use their strengths more often may be a valuable way to boost well-being in this population.

The substantial phenotypic heterogeneity in autism limits our understanding of its genetic etiology. To address this gap, here we investigated genetic differences between autistic individuals ( n max = 12,893) based on core and associated features of autism, co-occurring developmental disabilities and sex. We conducted a comprehensive factor analysis of core autism features in autistic individuals and identified six factors. Common genetic variants were associated with the core factors, but de novo variants were not. We found that higher autism polygenic scores (PGS) were associated with lower likelihood of co-occurring developmental disabilities in autistic individuals. Furthermore, in autistic individuals without co-occurring intellectual disability (ID), autism PGS are overinherited by autistic females compared to males. Finally, we observed higher SNP heritability for autistic males and for autistic individuals without ID. Deeper phenotypic characterization will be critical in determining how the complex underlying genetics shape cognition, behavior and co-occurring conditions in autism.

Autism and anxiety are thought to be related to extreme demand avoidance (EDA), which is characterised by intense avoidance of everyday demands. However, the relative importance of autism and anxiety to EDA has yet to be investigated, and little is known about EDA in adulthood. We conducted two online survey studies (Ns = 267 and 549) with adults in the general population to establish the relative importance of autistic traits and anxiety as predictors of demand avoidance, using dominance analysis. Both autistic traits and anxiety were unique and equally important predictors of demand avoidance. These findings suggest EDA is linked to autism and are consistent with the theory that demand avoidance behaviours are potentially anxiety-driven in adults.

Following the popularity of dual process models in social and cognitive psychology, there is major interest in the possibility that autism is associated with impaired "fast" intuitive thinking but enhanced "slow" or "rational" deliberative thinking. If correct, this has great potential to help understand various strengths and difficulties characteristic of autism. Previous empirical investigations of this phenomenon, however, are marred by concerns about the measurement of intuitive and deliberative processing, as well as broader problems in clinical psychological science (e.g., small underpowered studies, lack of replication). Making a step change, we conducted four large-scale studies to examine dual processing in autism, including a preregistered comparison of 200 autistic and nonautistic adults. Participants completed contemporary cognitive and self-report measures of intuitive and deliberative processing, as well as a psychometrically robust measure of general cognitive ability. Except for lower self-reported intuitive thinking, we found no unique contributions of autism to intuitive or deliberative thinking across all four studies, as evidenced by frequentist and Bayesian analyses. Overall, these studies indicate that intuitive and deliberative thinking is neither enhanced nor particularly impaired in relation to autism. We deliberate on the implications of these findings for theories of autism and future investigation of strengths and difficulties in autistic people.

The climate agenda has gathered extraordinary pace due to Greta Thunberg and other autistic environmentalists. Thunberg's autism is widely used to explain and celebrate, but also diminish and denigrate, her activism. However, despite speculation linking autism, pro-environmental action, and climate change belief, there is neither psychological theory nor empirical evidence on this topic. We therefore considered theoretical reasons for and against this potential association, and examined whether autistic traits were positively, if at all, linked to pro-environmental attitudes and behaviors, and climate change belief. In three preregistered studies (N = 2288), including nationally representative samples and well-powered frequentist and Bayesian analyses, we found substantial evidence that autistic traits were associated with engagement in fewer pro-environmental behaviors. Further, autistic traits were neither predictive of pro-environmental attitudes nor climate change belief. We conclude that, irrespective of environmental attitudes or climate change belief, autism and mental health conditions may present barriers for pro-environmental action. Suggestions for understanding the psychological factors underlying climate action and a more inclusive environmental agenda are discussed.

Mentalising, also known as "Theory of Mind", is the ability to understand and infer the cognitions of others, such as their perceptions, intentions, and beliefs. Although several tools have been designed to measure mentalising in adults, there exist methodological and practical limitations. Many of the existing measures conflate mentalising with similar constructs (e.g., empathy), and most are lengthy measures that are unsuitable for large population-based studies and clinical practice. These issues are currently hampering clinical and non-clinical investigations into mentalising and related social-cognitive abilities. Drawing on questionnaire measures of social cognition, we conceived a self-report mentalising scale, the Four-Item Mentalising Index (FIMI; Studies 1a and b). The FIMI was developed through a series of studies examining its factor structure and reliability (Studies 2a and b) and by testing its construct validity against a cognitive mentalising task, autistic traits, and comparing scores in autistic and non-autistic people (Studies 3a and b). Together, we demonstrate that the FIMI is a conceptually and methodologically robust tool for measuring mentalising ability in the general population, including autistic and non-autistic people. Future research directions and practical (clinical) applications of the scale are discussed, with a focus on improving understanding and management of (a)typical mentalising ability.

Lay abstract: The autonomic nervous system (ANS) is responsible for the functioning of the heart, bladder, pupils and several other bodily functions. Therefore, when the ANS functions abnormally, individuals can experience a number of physical symptoms, including dizziness, abnormal sweating and digestive difficulties. Currently, it is unclear if autistic adults experience ANS dysfunction. Therefore, in this study, we investigated whether autistic adults report more ANS-related physical symptoms, indicating greater ANS dysfunction, and whether this may be related to autism, or rather anxiety, depression, or stress. The findings suggest that ANS dysfunction, where found in autism, is due to co-occurring stress and anxiety. We therefore propose that treating stress and anxiety may be an effective way to ameliorate ANS-related health problems in autistic adults.

Karmic belief—the expectation that actions bring about morally congruent outcomes within and across lifetimes—is central to many, particularly Eastern, religions. This research (N = 704) examined whether karmic beliefs and cultural context (predominantly Christian Americans and Hindu Indians) moderated the indirect effect of learning about others’ morally congruent or incongruent negative outcomes on immanent justice reasoning (causally attributing misfortune to someone’s prior misdeeds) through perceived deservingness. Results revealed that the indirect effect of congruency on immanent justice attributions via deservingness was stronger for people higher in karmic beliefs, because they strengthened the effect of congruency on immanent justice attributions and the relationship between deservingness and immanent justice attributions. The indirect effect of congruency on immanent justice attributions through deservingness was also stronger in the United States. These results highlight the role that karmic beliefs play in how people reason about the causes of others’ fortunes and misfortunes.

The 10-item Autism-Spectrum Quotient (AQ10) is a self-report questionnaire used in clinical and research settings as a diagnostic screening tool for autism in adults. The AQ10 is also increasingly being used to quantify trait autism along a unitary dimension and correlated against performance on other psychological/medical tasks. However, its psychometric properties have yet to be examined when used in this way. By analysing AQ10 data from a large non-clinical sample of adults ( n = 6,595), we found that the AQ10 does not have a unifactorial factor structure, and instead appears to have several factors. The AQ10 also had poor internal reliability. Taken together, whilst the AQ10 has important clinical utility in screening for diagnosable autism, it may not be a psychometrically robust measure when administered in non-clinical samples from the general population. Therefore, we caution against its use as a measure of trait autism in future research.
