Using external morphology as a proxy for stomach size in Hemigrapsus sanguineus.

Stomach morphology can provide insights into an organism's diet. Gut size or length is typically inversely related to diet quality in most taxa, and has been used to assess diet quality in a variety of systems. However, it requires animal sacrifice and time-consuming dissections. Measures of external morphology associated with diet may be a simpler, more cost-effective solution. At the species level, external measures of the progastric region of the carapace in brachyuran crabs can predict stomach size and diet quality, with some suggestion that this approach may also work to examine individual diet preferences and specialization at the individual level; if so, the size of the progastric region could be used to predict trends in diet quality and consumption for individuals, which would streamline diet studies in crabs. Here, we tested whether external progastric region size predicts internal stomach size across latitude and time of year for individuals of the invasive Asian shore crab Hemigrapsus sanguineus. We found that the width of the progastric region increased at a faster rate with body size than stomach width. In addition, the width of the progastric region followed different trends across sites and over time compared to stomach width. Our results therefore suggest that the progastric region may not be used as a proxy for stomach size variation across individuals.

Shift from income breeding to capital breeding with latitude in the invasive Asian shore crab Hemigrapsus sanguineus.

Organisms vary in the timing of energy acquisition and use for reproduction. Thus, breeding strategies exist on a continuum, from capital breeding to income breeding. Capital breeders acquire and store energy for breeding before the start of the reproductive season, while income breeders finance reproduction using energy acquired during the reproductive season. Latitude and its associated environmental drivers are expected to heavily influence breeding strategy, potentially leading to latitudinal variation in breeding strategies within a single species. We examined the breeding strategy of the Asian shore crab Hemigrapsus sanguineus at five sites spanning nearly 10° of latitude across its invaded United States range. We hypothesized that the primary breeding strategy of this species would shift from income breeding to capital breeding as latitude increases. We found that though this species' breeding strategy is dominated by capital breeding throughout much of the range, income breeding increases in importance at lower latitudes. This latitudinal pattern is likely heavily influenced by the duration of the foraging and breeding seasons, which also vary with latitude. We also found that reproductive characteristics at the northern and southern edges of the invaded range were consistent with continued range expansion. We suggest that the reproductive flexibility of the Asian shore crab is a key facilitator of its continued invasion success. Our results highlight the influence of latitude on the breeding strategy of a species and emphasize the need for further research regarding the ecological importance and implications of flexibility in breeding strategies within species.

Autistic identity: A systematic review of quantitative research.

Autism can be considered both a personal and social identity. Identifying the factors contributing to positive Autistic identity development is crucial given the potential implications for mental health and wellbeing. In this systematic review, we aimed to synthesize quantitative literature on Autistic identity to identify the (individual and environmental) factors associated with Autistic identity, and to ascertain the relationship between Autistic identity and mental health and wellbeing. A total of 3,617 studies were screened and 20 met our inclusion criteria. Results indicated that people developed a more positive Autistic identity when receiving external autism acceptance and external support. The association between individual factors and Autistic identity were largely nonsignificant or inconclusive, highlighting the need for broad support that meets the needs of a range of Autistic people, rather than specific subgroups. Importantly, positive Autistic identity was associated with improved mental health and wellbeing. Peer support and/or self-directed support resources may be valuable mechanisms for supporting Autistic people to cultivate a positive Autistic identity. The evaluation of such support, including the long-term impacts on identity development, will be a critical avenue for future research.

'Who, When, How to Share': Pilot study of a new disclosure decision-making programme for autistic adults.

LAY ABSTRACT: 'Who, When, How to Share' is a new programme that aims to support autistic adults in making decisions around sharing their autistic identity with others. The programme involves working through a self-help guide independently over 3 weeks with optional peer support. We wanted to find out if autistic adults would join the programme and find it useful. Thirty-two autistic adults took part in the programme and 19 of them completed it. Most participants who completed the programme liked the programme and found it helpful, but some felt that they needed more time and support to complete it. They suggested that the programme would be more accessible if it was more interactive, such as including videos and other ways to gain feedback on their progress. Surveys filled in by participants before and after the programme suggested that they became more confident and less stressed about sharing their autistic identity with others, but some felt they still needed to build more confidence in order to handle negative attitudes from others. More work is needed to improve and test the programme further.

Dropping the mask: It takes two.

LAY ABSTRACT: In some situations, autistic people feel pressure to change their social behaviour by camouflaging. In other situations, autistic people feel they don't need to change their social behaviour. Instead, they feel they can socialise in ways that feel authentic or true to themselves. Past research has tended to focus on autistic people's experiences of camouflaging rather than their experiences of authenticity. In this study, we asked autistic people what it is like for them when they can socialise in ways that feel authentic or true to themselves. Autistic people described authentic-feeling socialising as more free, spontaneous and open than camouflaging. In supportive environments, this kind of socialising had more positive and less negative consequences than camouflaging. Autistic people felt that having self-awareness and acceptance of their own social needs and being around autistic and nonautistic people who were accepting and understanding helped them to socialise in authentic-feeling ways. Autistic people also spoke about communication behaviours they felt nonautistic people should use to help overcome misunderstandings and create autism-friendly social environments. These findings suggest it is helpful for autistic people to have access to supportive and accepting social environments in which they feel able to socialise in ways that feel authentic to them. In creating such social environments, it is important to focus on nonautistic people's knowledge and attitude towards autistic people and also their ability to use helpful communication behaviours.

Letter to the Editor: A possible threat to data integrity for online qualitative autism research.

LAY ABSTRACT: Doing research online, via Zoom, Teams, or live chat, is becoming more and more common. It can help researchers to reach more people, including from different parts of the world. It can also make the research more accessible for participants, especially those with different communication preferences. However, online research can have its downsides too. We have recently been involved in three studies in which we had in-depth discussions with autistic people and/or parents of autistic children about various topics. It turns out, though, that some of these participants were not genuine. Instead, we believe they were "scammer participants": people posing as autistic people or parents of autistic children, possibly to gain money from doing the research. This is a real problem because we need research data that we can trust. In this letter, we encourage autism researchers to be wary of scammer participants in their own research.

'It seems like a luxury to be able to offer that': Factors influencing the implementation of annual health checks for autistic people in England.

LAY ABSTRACT: Autistic people are more likely to have mental and physical health problems than non-autistic people. Annual health checks could reduce these problems by finding and treating them early. Annual health checks are yearly medical appointments where a primary healthcare provider (such as a doctor or nurse) can check things like a patient's weight and heart rate and ask if they have any worries about their health. In this study, we wanted to understand what might encourage primary healthcare providers to use annual health checks with their autistic patients. First, we spoke to 10 autistic people and 11 primary healthcare providers. Using the findings from these conversations, we created an online survey for primary healthcare providers in England. We used the findings from the interviews and survey to help us understand what would encourage primary healthcare providers to offer annual health checks for autistic people. Our participants said that a lack of time and staff would make it hard to provide health checks. To help, they said other members of staff (such as nurses and healthcare assistants) could do the health checks, rather than doctors. They also said parts of the process could be made automatic to save time (e.g. sending automatic reminders). Knowledge about autism was important too (e.g. knowing about the common conditions autistic people have, and how to best support autistic patients). Participants said training on these topics, produced and delivered with autistic people, could encourage them to use annual health checks with their autistic patients.

Disclosing an autism diagnosis improves ratings of candidate performance in employment interviews.

LAY ABSTRACT: Employment interviews are challenging for many autistic people, for example, due to difficulties with interpreting questions. Autistic people also have differences in non-verbal communication, such as emotional expression, eye-contact, and gestures, with research showing that these factors negatively affect first impressions. Some studies have shown that perceptions of autistic people are more positive when the person observing them, such as an interviewer, is already aware of their diagnosis. However, previous research has not studied how disclosing one's autism diagnosis affects perceptions of a candidate undergoing a full employment interview. Participants in this study acted as raters, who watched a video of an autistic person undergoing a mock employment interview with a researcher, and then rated their overall impressions of them on factors important to real-world hiring decisions, such as confidence, motivation, and knowledgeability. Prior to watching the interview, raters were either (1) not aware of the interviewee's diagnosis, (2) made aware of their diagnosis, or (3) made aware of their diagnosis and provided with additional information about autism, such as differences in behaviours and communication. The results show that disclosing an autism diagnosis improved ratings compared to not disclosing the diagnosis. Providing additional information about autism alongside the diagnostic label did not improve ratings further. The findings are important for employers and autistic people; employers should consider improving procedures by which autistic people can disclose their diagnosis prior to interview should they wish, and autistic people may wish to consider the potential benefits of disclosing their diagnosis.

Evaluating measures to assess loneliness in autistic adults.

LAY ABSTRACT: There has been increasing interest in research on loneliness in autistic adults. Much of this research has involved giving autistic adults widely-used questionnaires that are thought to measure how lonely people are. However, these questionnaires have been developed for the general public. We do not know whether these questionnaires accurately measure how lonely autistic adults are. We asked 203 autistic adults to complete an online survey that included two widely-used loneliness questionnaires: (1) the University of California, Los Angeles (UCLA) Loneliness Scale Version 3 and (2) the Social and Emotional Loneliness Scale for Adults (SELSA). We also asked participants to rate how lonely they were from 1 (often/always) to 5 (never). Participants were then asked to give their views on the questionnaires (e.g. what they thought was good, and what they thought was not so good about them). We found that the scores on the UCLA scale and the SELSA aligned with participants' ratings of how lonely they were, which suggests that these two questionnaires accurately measure loneliness in autistic people. However, our participants also identified several ways to improve the questionnaires. This included (1) better distinguishing the characteristics/experiences of loneliness from those of being autistic; (2) better reflecting how loneliness may change at different times and in different contexts and (3) making the phrasing of the questions clearer. Overall, our autistic participants tended to prefer the UCLA scale to the SELSA. Therefore, we present some recommendations about how the UCLA scale could be changed to be more suitable for autistic people.

Evaluating a new supported employment internship programme for autistic young adults without intellectual disability.

LAY ABSTRACT: Internships designed for autistic people can help them to find employment, but there is little research about the experiences of those involved with internship schemes. To learn more about a new paid internship scheme in the United Kingdom, the Employ Autism network, we interviewed 19 interns, who were autistic young adults without intellectual disability taking part in one of eight different internships. We also interviewed 22 employers (who worked with the interns), and 10 parents (who supported their children in the internship). The interns, employers and parents told us that the Employ Autism network was a valuable experience that helped the interns become more confident. Also, the parents said it helped the interns become more independent. All the groups said the Employ Autism network removed common barriers to employment, and interns and parents said it would help interns get a job in future. Employers and interns said they understood each other better during the internship, and employers said the internship made them think about how their organisations might have accidentally had barriers in place that could stop autistic people getting employed (barriers that they wanted to address in future). However, all groups said some expectations of the internship were not met. These findings suggest the Employ Autism network is helpful for autistic young adults without intellectual disability and employers, but that there are ways that the internships could be improved in future. We discuss the lessons we can learn from the Employ Autism network that might help others who are thinking about setting up, or getting involved in, similar internship schemes.

Past energy allocation overwhelms current energy stresses in determining energy allocation trade-offs.

Regeneration of lost appendages is a gradual process in many species, spreading energetic costs of regeneration through time. Energy allocated to the regeneration of lost appendages cannot be used for other purposes and, therefore, commonly elicits energetic trade-offs in biological processes. We used limb loss in the Asian shore crab Hemigrapsus sanguineus to compare the strength of energetic trade-offs resulting from historic limb losses that have been partially regenerated versus current injuries that have not yet been repaired. Consistent with previous studies, we show that limb loss and regeneration results in trade-offs that reduce reproduction, energy storage, and growth. As may be expected, we show that trade-offs in these metrics from historic limb losses far outweigh trade-offs from current limb losses, and correlate directly with the degree of historic limb loss that has been regenerated. As regenerating limbs get closer to their normal size, these historical injuries get harder to detect, despite the continued allocation of additional resources to limb development. Our results demonstrate the importance of and a method for identifying historic appendage losses and of quantifying the amount of regeneration that has already occurred, as opposed to assessing only current injury, to accurately assess the strength of energetic trade-offs in animals recovering from nonlethal injury.

Evaluating the online delivery of an autistic-led programme to support newly diagnosed or identified autistic adults.

Background & aims: Exploring Being Autistic is an autistic-led group-based programme providing psychoeducation and peer support to newly identified/diagnosed autistic adults. In 2020, due to social distancing measures implemented following the coronavirus pandemic, Exploring Being Autistic was adapted for online delivery. Here, we aimed to replicate previous research into the in-person delivery of Exploring Being Autistic, to determine whether similar results were obtained when the programme was delivered online. Further, we aimed to identify the unique opportunities and challenges that online delivery afforded. Methods: We used a community-based participatory research (CBPR) approach, whereby the autistic developer and facilitator of Exploring Being Autistic worked collaboratively with a team of academic researchers throughout the research process. Together, we evaluated two iterations of the online Exploring Being Autistic programme, involving 16 attendees. Attendees completed questionnaires before, during and after the programme. Attendees were also invited to participate in two post-programme (group or individual) interviews: one following the completion of the programme (time one) and another 6-8 months later (time two). Attendees were included in the research if they completed at least one questionnaire or interview. Data were analysed qualitatively, using reflexive thematic analysis. Results: Experiences of participating in the programme tended to be positive. Participants appreciated the autistic-led nature of the programme, found unity in the diversity of the group, and developed a positive and practical outlook as a result of the programme. Further analyses of our data revealed mixed views regarding the online delivery of the programme. Opportunities of online delivery were noted, such as this mode of participation reducing cognitive load, enabling the programme to be accessible to more participants, and fostering meaningful social connections among participants. However, technology and practical issues were felt to cause barriers, and some human aspects of participation were felt to be 'lost in translation' (e.g., in breakout groups). Conclusions: The online delivery of the Exploring Being Autistic programme yielded similar results to previous, in-person evaluations of the programme. While we identified positive aspects of online delivery, this mode did not entirely suit everyone's needs. Implications: From the current findings, we can make several recommendations to develop online support for autistic people. First, flexibility is key. To make support accessible and inclusive to a broad range of autistic people, the option for attendees to engage in-person, online or in hybrid formats should be considered. Second, if delivering support online, the use of breakout rooms should be carefully considered. While participants appreciated the opportunity to meet different people, some participants found the unpredictability and lack of scaffolding associated with breakout rooms challenging. To mitigate these challenges, groups could be pre-determined and shared with the attendees in advance (although consideration should be given to how the groups 'fit' together, and whether groupings should be changed at set intervals). Gentle warnings should also be given to those in breakout rooms, to alert them of the need to re-join the main group. Finally, support with technological aspects relating to engagement should be prioritised.

Impact of the COVID-19 Pandemic on Autistic Adults: a Scoping Review.

Purpose of Review: The COVID-19 pandemic and its associated restrictions have had a significant impact on people's everyday lives, including the lives of Autistic adults. We aimed to (a) synthesise all papers currently published on the impact of the COVID-19 pandemic on autistic adults and (b) identify lessons for the care and support of Autistic adults in pandemic and post-pandemic times. Recent Findings: Fifty-five papers met the inclusion criteria. Most studies focused on the pandemic's impact on the wellbeing of Autistic adults. Several studies focused on the use of (telehealth) services or the risk of COVID-19 infection/hospitalisation. Summary: Autistic adults were significantly impacted by the pandemic, both directly as indicated by higher COVID-19 infection and hospitalisation rates, but also indirectly due to severe service disruptions and social restrictions. Even though there were large differences observed both between as well as within individuals in terms of the negative/positive effects of the COVID-19 pandemic, most studies reported a negative effect on Autistic adults' mental health. We draw several lessons from this review for the future care and support of Autistic adults, all of which must be underpinned by participatory research methods, that is, where Autistic community members are actively involved in setting research questions, testing the acceptability of the methods and interpreting and disseminating the results.

Development of stigma-related support for autistic adults: Insights from the autism community.

LAY ABSTRACT: Many autistic adults experience public stigma, which refers to negative attitudes and treatment from others. Because of that, some autistic adults may also apply unhelpful beliefs to themselves, which is known as internalised stigma. There is some evidence that both public stigma and internalised stigma are linked to poorer mental health in autistic adults. Clearly, it is crucial to change how society thinks and acts towards autistic people. There are several programmes that are trying to do this. But as change can be slow, support may also be needed to help autistic people cope with and challenge stigma. Using an online survey, we gathered the views of 144 autistic adults and parents/caregivers of autistic people in the United Kingdom on whether a stigma support programme for autistic adults is needed and, if so, what it should 'look' like. Most participants felt it was important for autistic adults to have support in managing stigma because of the harmful effects that stigma has on mental health and the challenges that autistic adults face in disclosing their diagnosis. However, participants were also concerned that such a programme could convey the message that autistic people, rather than society, need to change. Participants suggested that the programme should be positive and practical, helping autistic adults to understand and accept themselves, as well as learn context-specific strategies for responding to stigma and/or disclosing their diagnosis. They also stressed that the programme should be flexible and inclusive, recognising that autistic adults have very different needs and preferences.

Benefits and harms of interventions to improve anxiety, depression, and other mental health outcomes for autistic people: A systematic review and network meta-analysis of randomised controlled trials.

LAY ABSTRACT: Nearly three out of four autistic people experience mental health problems such as stress, anxiety or depression. The research already done does not guide us on how best to prevent or treat mental health problems for autistic people. Our aim was to look at the benefits and harms of different interventions on mental health outcomes in autistic people. We searched all the published randomised controlled trials (RCTs) about interventions for mental health conditions in autistic people until 17 October 2020. We also searched for RCTs that were not published in peer-reviewed journals. These were obtained from registers of clinical trials online. We then combined the information from all these trials using advanced statistical methods to analyse how good the interventions are. Seventy-one studies (3630 participants) provided information for this research. The studies reported how participants were responding to the intervention for only a short period of time. The trials did not report which interventions worked for people with intellectual disability. In people without intellectual disability, some forms of cognitive behavioural therapy and mindfulness therapy may be helpful. However, further research is necessary. Many trials used medications to target core features of autism rather than targeting mental health conditions, but these medications did not help autistic people. Until we have more evidence, treatment of mental health conditions in autistic people should follow the evidence available for non-autistic people. We plan to widely disseminate the findings to healthcare professionals through medical journals and conferences and contact other groups representing autistic people.

Latitudinal and temporal variation in injury and its impacts in the invasive Asian shore crab Hemigrapsus sanguineus.

Nonlethal injury is a pervasive stress on individual animals that can affect large portions of a population at any given time. Yet most studies examine snapshots of injury at a single place and time, making the implicit assumption that the impacts of nonlethal injury are constant. We sampled Asian shore crabs Hemigrapsus sanguineus throughout their invasive North American range and from the spring through fall of 2020. We then documented the prevalence of limb loss over this space and time. We further examined the impacts of limb loss and limb regeneration on food consumption, growth, reproduction, and energy storage. We show that injury differed substantially across sites and was most common towards the southern part of their invaded range on the East Coast of North America. Injury also varied idiosyncratically across sites and through time. It also had strong impacts on individuals via reduced growth and reproduction, despite increased food consumption in injured crabs. Given the high prevalence of nonlethal injury in this species, these negative impacts of injury on individual animals likely scale up to influence population level processes (e.g., population growth), and may be one factor acting against the widespread success of this invader.

Loneliness in autistic adults: A systematic review.

LAY ABSTRACT: Recently, researchers have been interested in how autistic people experience loneliness. Yet, most of this research has focused on loneliness in autistic children and young people. We present the results of a systematic review on loneliness in autistic adults. A systematic review is a rigorous way of searching for all existing research on a topic and summarizing the findings about specific questions. We searched for all research published on this topic until 9 April 2021. We found 34 articles that investigated loneliness in autistic adults. This research showed that (1) there is fairly little research that has involved directly asking autistic adults about their first-hand experiences of loneliness (e.g. what loneliness feels like for them); (2) few research studies have used loneliness questionnaires specifically developed for autistic adults (this was attempted in just one research study); (3) collective loneliness (i.e. loneliness associated with how much an autistic person feels they 'fit in' to society) seems important to autistic adults but has not been investigated as commonly as other aspects of loneliness (e.g. loneliness associated with romantic relationships or friendships); (4) things that might increase loneliness in autistic adults include anxiety and depression, and a lack of autism understanding and acceptance, for example; and (5) things that might reduce loneliness in autistic adults include having relationships and self-acceptance, for example. In our article, we discuss the kinds of future research on loneliness in autistic adults that might be useful.

The impact of early stages of COVID-19 on the mental health of autistic adults in the United Kingdom: A longitudinal mixed-methods study.

LAY ABSTRACT: During the COVID-19 pandemic, high levels of depression, anxiety and stress have been reported in the general population. However, much less has been reported about the impact of COVID-19 on the mental health of autistic people. What we did: In the present study, we investigated how the mental health of autistic adults in the United Kingdom changed during the early stages of the COVID-19 pandemic. In total, 133 participants completed an online survey at two different time points. Of the 133 participants, 70 completed the survey at the first time point just before the onset of the national lockdown. This allowed us to look at changes in their mental health, from before the lockdown to 10 to 15 weeks during lockdown. All participants (133) told us about their experiences of the pandemic. What we found: While many autistic adults told us that their mental health worsened, people's experience varied. For some autistic adults, aspects of mental health (e.g. anxiety, stress) actually improved. Participants also described social changes that had occurred, at home and in the outside world. They described feelings of uncertainty during the pandemic, and discussed how the pandemic had affected some of their previous coping strategies. Participants also told us about their difficulties in accessing healthcare services and food during the early stages of the pandemic. In our article, we discuss these findings and focus on what needs to change to ensure that autistic people are better supported as the pandemic continues.

Participatory autism research: Early career and established researchers' views and experiences.

LAY ABSTRACT: 'Participatory autism research' refers to ways of involving autistic people and their allies (e.g. family members) in making decisions about research. These decisions can include what research gets done, how it gets done and how research findings are used. While there is more and more interest in participatory autism research, we know little about how researchers at different stages of their careers use this approach. To find out more, we discussed these issues with 25 researchers. Fourteen of these were at an early stage of their careers, and 11 were more senior researchers. We spoke to people in individual interviews or in groups. We then used a technique called thematic analysis to analyse our data, which involved us looking for common topics or 'themes' discussed by our participants. What did we find? Our participants told us that participatory autism research was a flexible approach, meaning that autistic people can be involved in research in many different ways. While people viewed this flexibility in a positive way, it also caused some confusion about what does or does not 'count' as participatory research. Our participants also spoke about how important it was to build relationships with those involved in their research, but they also said it could be difficult to communicate well with diverse groups of people who may not have much experience of research. Finally, our participants said it was hard to do participatory research when there was not much time, funding or support available to researchers. In this article, we discuss these findings, focusing on what needs to change to ensure that autistic people and their allies are meaningfully involved in autism research.
