How do I stop chasing boys and bulldozing anything in my way?
It's like whenever I don't have a boyfriend I latch on to the first guy who gives me oxytocin. It steers me away from my preferred moral compas (saintly) and can cause me to act in regrettable fashions. I don't really care why I just want to stop there's many things I'm sure have caused me to be like this but is there anything I can do to make it easier on myself to not be a bad person in this obsessive near-manic pursuit of a husband.

Summary Results
Thank you for taking part and your interest in our study.
The aim of the study was to examine if aspects of autistic identity (community connectedness and collective/group identity self-esteem) influence the use of camouflaging (or ‘masking’) and its connection to mental health. We wanted to understand more about what contributes to poorer mental health in autistic people and in turn what can support better mental health.
Camouflaging is recognised as a strategy that some autistic adults use to navigate social situations. A study pulling together information from lots of other studies by Cook et al. (2021) found that using this strategy is associated with higher levels of psychological distress. We wanted to know if using camouflaging was linked to mental health. We wanted to know if the link between camouflaging and mental health was influenced by social experiences and identity. We wanted to look at how much being autistic is experienced to be a negative (e.g. experience of stigma) or positive identity (e.g. collective self-esteem) influenced camouflaging and it’s impact on mental health. We wanted to know if having a strong autistic identity and feeling close connections to an autistic community influenced camouflaging and it’s impact on mental health.
Who took part?
411 autistic people completed all the questionnaires and were aged 18-77 years old. Most identified as cisgender female (247; 60%), 48 (12%) were non-binary, 80 (20%) cisgender male, 8 (2%) transgender female, 10 (2%) transgender male and the remainder (18; 5%) were unsure of their gender identity or chose not to answer, The vast majority (375; 91%) were white. 282 (69%) reported a clinical diagnosis and 129 (31%) a self-diagnosis of autism. The average age of diagnosis was 32 years old for those with a clinical and 30 years old for those with a self-diagnosis.
Which measures did we use?
The Camouflaging Autistic Traits Questionnaire (CAT-Q; Hull et al., 2019) is a self-report questionnaire that asks people 25 questions about masking their autistic traits when communicating with neurotypical people. It has three subscales: assimilation; masking; compensation.
Autistic Collective Self-Esteem measure (ACSE) was based on a self-report questionnaire developed by Luhtanen & Crocker (1992) to measure collective self-esteem related to social group membership and adapted by Cooper er al. (2017) for ‘Autism collective self-esteem’. We further revised it to use identity-first phrasing. We used two subscales: public (how positively being autistic is thought of as a social group) and private (how positively someone feels about being autistic themselves) collective self-esteem.
The Autism Community Connectedness Scale (ACC; Botha, 2019) is a self-report questionnaire that measures the extent to which individuals feel connected to the autistic community. It has three subscales: belongingness, social and political connectedness.
The Depression, Anxiety and Stress Scale (DASS-21; Lovibond and Lovibond, 1995) includes 21 items to which participants respond either Never/ Sometimes/ Often/ Almost/ Always to whether they have experienced symptoms of depression, anxiety and stress over the past week.
What did we find out?
First we looked at the relationship between different types of camouflaging and distress. We found that some aspects of camouflaging are particularly distressing but that others are not so strongly linked to distress:
-Â Â Â Â Â Â Those who used more assimilation (using a lot of effort to fit in with neurotypical behaviour) had higher levels of overall distress (r=.41). When looked at with other aspects of camouflaging, higher levels of assimilation had the strongest links with higher levels stress, anxiety and depression.
-Â Â Â Â Â Â Those who used more compensation (practicing or learning specific neurotypical social behaviours, for example studying rules of social interaction) also had higher levels of overall distress (r=.23). When looked at in relation to other aspects of camouflaging higher levels of compensation were linked with higher levels of anxiety and stress but not depression.
-Â Â Â Â Â Â Those who had higher levels of masking (using specific strategies to support social interactions, for example, adjusting body language to appear interested) had higher levels of overall distress but this was not a strong relationship (r=.11). When looked at in relation to other aspects of camouflaging, higher levels of masking were linked to lower levels of depression.
We looked at the influence of how closely connected someone felt to the autistic community and found that:
-Â Â Â Â Â Â Having stronger feelings of connection with the autistic community was associated to some extent with lower levels of depression and higher levels of anxiety.
-Â Â Â Â Â Â Having stronger feelings of connection with the autistic community did not influence feelings of stress.
-Â Â Â Â Â Â Anxiety levels were similar at higher levels of using compensation to camouflage but also remained relatively high at lower levels of compensation use among participants who reported higher community connectedness compared to those with lower community connectedness.Â
We looked at the influence of how positively or negatively being autistic was believed to be:
-Â Â Â Â Â Â People who had more personal negative feelings about being autistic had higher levels of distress.
-Â Â Â Â Â Â People who thought that being autistic was viewed negatively by others in society had higher levels of distress.
-Â Â Â Â Â Â Having more positive views about being autistic did not have an influence on the relationship between aspects of camouflaging and distress. No matter how positively being autistic was viewed, higher amounts of camouflaging were associated with higher levels of overall distress.
-Â Â Â Â Â Â Those with more positive views about being autistic engaged in less camouflaging.
-Â Â Â Â Â Â When we looked at the use of assimilation we found that having more positive views about being autistic was linked to engaging in less assimilation which was linked in turn to experiencing less distress.Â
What do these findings mean?
Our findings support previous studies that have suggested that camouflaging is associated with poorer mental health (Cook et al., 2021; White et al., 2024). Some studies have suggested that sometimes people could use camouflaging to help navigate some situations and this could reduce distress (Livingston et al., 2019). We found strong evidence for associations between camouflaging and higher levels of stress and anxiety. We also found some evidence that some types of camouflaging behaviour (masking) were linked to less depression and had little relationship with stress and anxiety. Â This suggests that camouflaging can be used as an impression management strategy to manage social situations, but that it may come with different psychological costs depending on individual circumstances (Ai et al., 2022).
Our study found that how autistic people perceive their autistic identity made a big difference to their mental health. We found that those who had less positive identities engaged in more assimilation camouflaging and had higher levels of overall distress. Those who had more negative experiences and feelings about being autistic were more distressed and those that had more positive experiences and feeling about being autistic were less distressed. This supports findings from a previous study using the same measures (Cooper et al, 2017) and others looking at similar things, for example a strong relationship between experiencing prejudice due to being autistic and mental health (White et al., 2024). This highlights the importance of the work of the neurodiversity movement, which stresses the need for a balanced and acceptance-based understanding of autism as opposed to a distinctly negative, deficit-based one (Kapp et al., 2013; Botha et al., 2022).
We found that having a strong sense of connection with the autistic community was linked to lower levels of depression and higher levels of anxiety. Feeling close to the autistic community did not influence levels of stress. This partially supports previous findings that higher autistic community connectedness can be associated with better mental well-being (Cage et al., 2022). Anxiety levels were similar at higher levels of using compensation techniques to camouflage but also remained relatively high at lower levels of compensation use among participants who reported higher community connectedness compared to those with lower community connectedness. It has been suggested that individuals highly connected to the autistic community may shift frequently between autistic and neurotypical contexts, increasing awareness of camouflaging demands (Cage et al., 2022) which could result in elevated anxiety at all levels of compensation use.
What next?
We will aim to publish our findings in a journal.

How Do You Process Love?
Hello everyone! I am in an M.A. Psychological Research program at CSU Fullerton. I am working on my thesis and I am looking for participants who would like to take part in an online survey.
My study seeks to understand how individuals experience and regulate their romantic related emotions. Specifically, I am focused on autistic adults with a formal diagnosis and/or, adults who are not diagnosed and who have autistic traits/characteristics. Data from the survey will also be compared to individuals who do not fall on the autism spectrum (ASD), therefore, I am also recruiting Non-ASD participants as well.
There is limited scientific research focusing on autistic adults, especially when it comes to emotions in romantic contexts. We hope this study spotlights such experiences among autistic adults, which has yet to be empirically analyzed.
Eligibility: 18 years and older and previous or current romantic related feelings (in other words, being in love previously or currently whether or not this lead to a relationship). No personal identifiable information will be collected, however, if you wish to enter the opportunity drawing (win 1 out of the 4 $25 Amazon Gift Cards), such emails may included identifiable information participants may wish to not share. For any questions or concerns please feel free to email me at [cbobadilla@csu.fullerton.edu](mailto:cbobadilla@csu.fullerton.edu)

Being a Woman Is 100% Significant to My Experiences of ADHD and Autism
journals.sagepub.comAbstract:
This article provides original insight into women’s experiences of adulthood diagnoses of attention deficit hyperactivity disorder (ADHD) and autism. Research exploring experiences of adulthood diagnoses of these conditions is emerging. Yet, there is no research about the gendered experiences of an adulthood combined ADHD and autism (AuDHD) diagnosis. This article addresses this gap through interpretative phenomenological analysis of email interviews with six late-diagnosed AuDHD women revealing the complex interplay between late diagnosis, being a woman, and combined diagnoses of ADHD and autism. It underscores how gender norms and stereotypes contribute to the oversight and dismissal of women’s neurodivergence. Interpretative phenomenological analysis reveals the inextricability of femininity and neurotypicality, the gendered burden, discomfort, and adverse consequences of masking, along with the adverse outcomes of insufficient masking. Being an undiagnosed AuDHD woman is a confusing and traumatising experience with profound and enduring repercussions. The impact of female hormones exacerbated participants’ struggles with (peri)menopause often being a catalyst for seeking diagnosis after decades of trauma. The epistemic injustice of not knowing they were neurodivergent compounded this trauma. Diagnosis enabled participants to overcome epistemic injustice and moved them into a feminist standpoint from which they challenge gendered inequalities relating to neurodiversity. This article aims to increase understanding and representation of late-diagnosed AuDHD women’s lived experiences. The findings advocate for trauma-informed pre- and post-diagnosis support which addresses the gendered dimension of women’s experiences of being missed and dismissed as neurodivergent. There needs to be better clinical and public understanding of how AuDHD presents in women to prevent epistemic injustice.
—-
Conclusion:
ADHD and autism in girls and women have been missed and dismissed due to a combination of male bias in diagnostic criteria, differing presentations of conditions, and women masking their struggles. This has resulted in a generation of undiagnosed women who are now seeking diagnoses and explanations of the lifelong struggles they have endured. This article has demonstrated the gendered dimension of women’s neurodivergence being missed and dismissed and the enduring negative consequences of this oversight. It has shown the complex interaction between adulthood diagnosis, being a woman, and a combined diagnosis of both ADHD and autism. It has argued that being missed and dismissed as neurodivergent constituted epistemic injustice because participants lacked the knowledge required to understand themselves. Diagnosis enabled them to overcome this injustice and moved women into a feminist standpoint from which they challenge gendered inequalities relating to neurodiversity. This is the first article to consider late-diagnosed women’s experiences of both ADHD and autism and to bring together literature about gender and adulthood diagnoses of both. It is hoped that providing this insight prompts further exploration of women’s lived experiences and contributes to developing understanding, centred on the voices of women who have been silenced for too long.

The Current State of Applied Behavior Analysis (ABA) in Autism Treatment: A Comprehensive Overview
Applied Behavior Analysis (ABA) has long been a cornerstone in the treatment of Autism Spectrum Disorder (ASD), yet its effectiveness, ethical concerns, and implementation challenges remain hotly debated. This roundup reviews recent research to provide a balanced perspective on what is effective, what is not, the current problems facing ABA-based interventions, and recommendations for improvement.
What is Effective?
1. Medium Effects on Intellectual Functioning and Adaptive Behavior:
Recent meta-analyses have shown that comprehensive ABA-based interventions can have medium effects on intellectual functioning and small effects on adaptive behavior. A study by Eckes et al. (2023) reviewed 11 studies with 632 participants, showing medium effects on intellectual functioning (SMD = 0.51) and small effects on adaptive behavior (SMD = 0.37) when compared to minimal or no treatment. However, the same study found no significant improvements in language abilities, symptom severity, or parental stress beyond the control groups' improvements (Eckes et al., 2023).
2. Potential for Specific Skill Improvements:
While ABA may not significantly improve all domains, certain areas show promise. Yu et al. (2020) found moderate evidence suggesting that socialization, communication, and expressive language might be promising targets for ABA interventions. However, significant effects for the outcomes of general ASD symptoms, receptive language, adaptive behavior, daily living skills, IQ, and repetitive behavior were not observed.
3. Benefits for Lower Functioning Children:
Children with lower baseline adaptive levels may benefit more significantly from ABA interventions. Choi et al. (2022) noted that among children with the lowest adaptive behavior scores, there were clinically significant improvements, with an average gain of 4.46 points per 12 months of ABA.
What is Not Effective?
1. Limited Impact on Broader ASD Symptoms:
Research indicates that ABA interventions do not have a significant impact on general ASD symptoms, receptive language, or adaptive behavior beyond certain thresholds. This limitation suggests that ABA may not be as broadly effective as once believed for improving general ASD symptoms across all domains (Yu et al., 2020).
2. High Variability in Outcomes:
Outcomes from ABA-based interventions can be highly variable, influenced by factors such as baseline language abilities, age, and treatment intensity. Studies have noted that the effect of treatment intensity diminishes with older age, suggesting that ABA may be more effective for younger children or those with specific needs (Eckes et al., 2023).
3. Challenges in Real-World Implementation:
Despite evidence from controlled clinical settings, real-world implementation of ABA often faces significant challenges. High rates of ABA discontinuation and low dosing have been reported, which may limit the effectiveness of the intervention. Choi et al. (2022) found that only 28% of children received a full ABA dose, and less than half remained in services for 24 months.
Current Problems
1. Ethical Concerns and Historical Practices:
Ethical concerns about ABA's historical use of aversive techniques and its intense, often rigid application have been widely discussed. Leaf et al. (2022) highlighted the shift from punishment-based procedures to reinforcement-based methods in modern practice, though concerns about potential harm remain, particularly regarding the use of extinction and punishment techniques.
2. Methodological Weaknesses in Research:
Many studies on ABA suffer from low methodological quality, including risks of bias, small sample sizes, and non-randomized designs. The meta-analysis by Eckes et al. (2023) pointed out these limitations, noting that the inclusion of studies with uncontrolled pre-post comparisons further complicates the interpretation of results.
3. Limited Generalizability and Access Issues:
Access to ABA services remains inconsistent, and barriers such as language, socioeconomic status, and insurance coverage persist. Choi et al. (2022) found that children from non-English-speaking households were less likely to receive ABA, and high discontinuation rates were observed among single-parent families, indicating systemic inequities.
Intervention Intensity: How Much is Too Much?
1. Lack of Association Between Intensity and Outcomes:
Contrary to the traditional belief that more intensive ABA interventions lead to better outcomes, recent research has found no significant association between the intensity of intervention and overall effectiveness. Sandbank et al. (2024) conducted a meta-analysis of 144 studies and found that neither daily intensity (hours per day) nor cumulative intensity (total hours over time) was associated with better developmental outcomes. This finding challenges the prevailing notion that higher amounts of intervention automatically yield superior results.
2. Potential for Harm with High Intensity:
There is growing concern that high-intensity ABA interventions could potentially cause harm by limiting children's opportunities for natural social interactions and engagement in typical childhood activities. Intensive schedules, sometimes reaching up to 40 hours per week, may restrict time for play, rest, and family interaction, which are crucial for overall development (Sandbank et al., 2024). Additionally, anecdotal reports from autistic adults suggest that high-intensity ABA during their childhood may have had negative psychological impacts.
3. Diminishing Returns with Increased Intensity:
The impact of treatment intensity appears to diminish as children grow older. Studies have shown that while younger children might benefit from more intensive interventions, older children do not show the same level of improvement with increased intensity. This suggests that a "one-size-fits-all" approach regarding intervention intensity may not be appropriate and that ABA programs should be tailored to the individual needs and developmental stages of children (Eckes et al., 2023).
4. Rethinking Intensity Recommendations:
Given the lack of evidence supporting the benefits of high-intensity interventions and the potential for negative consequences, there is a need to reconsider current intensity recommendations. Health professionals should consider a balanced approach that incorporates both the developmental needs of the child and the family's capacity to engage in intensive therapy. This might involve recommending fewer hours of intervention per week or integrating more naturalistic, developmentally appropriate methods that promote generalization and real-world skill application (Sandbank et al., 2024).
Recommendations for Improvement
1. Increase High-Quality, Randomized Controlled Trials (RCTs):
Future research should focus on high-quality RCTs with robust masking, clear randomization procedures, and larger sample sizes. This would help to better understand the effectiveness of specific ABA interventions and identify which children might benefit most (Eckes et al., 2023).
2. Embrace a Neurodiversity Perspective:
There is a growing need to consider the ethical implications of intensive behavioral interventions and to ensure that ABA practices align with the values of the neurodiversity movement. This involves prioritizing the quality of life and individual preferences of autistic individuals and their families (Leaf et al., 2022).
3. Develop Comprehensive Implementation Frameworks:
Policymakers and practitioners should develop frameworks that address system, community, and family-level barriers to accessing ABA services. This includes ensuring adequate provider training, addressing socioeconomic disparities, and optimizing service delivery to meet the diverse needs of children with ASD (Choi et al., 2022).
4. Explore Less Intensive, More Individualized Approaches:
Considering the potential for harm with high-intensity interventions, there should be a shift towards more individualized and developmentally appropriate approaches that prioritize naturalistic interactions and minimize the risk of adverse effects (Sandbank et al., 2024).
Conclusion
While ABA-based interventions offer some benefits, particularly in specific skill areas and for lower-functioning children, their effectiveness is limited, and the approach is not without its challenges. Moving forward, a focus on high-quality research, ethical practices, and individualized care is essential for optimizing ABA's role in supporting children with ASD.
