Background: Awareness and recognition of autism have grown significantly in recent years. Despite this progress, research on the diagnosis and camouflaging behaviors in adult autistic women remains limited. This study seeks to address this gap by examining the characteristics of autism in adult women, with a particular focus on understanding the role of camouflaging in the challenges these women face in obtaining a formal diagnosis.Methods: Through a cross-sectional study involving 253 autistic participants, we administered a comprehensive battery of psychological assessment instruments to collect data on autistic traits, camouflage behaviors, stress, anxiety, depression, and diagnosis/suspicion-related factors.Results: Our findings revealed that the traits and characteristics of autism did not significantly differ between women and men or non-binary individuals. However, there were significant delays in the formal identification of autism in women, who had a lower rate of early autism diagnosis compared with other genders. In contrast, women often received prior diagnoses of other psychological conditions before their autism was identified. While camouflage behaviors were significantly more common among women than men, these patterns did not directly explain the delay in suspicion and diagnosis in this population. Although camouflaging predicted higher levels of anxiety, stress, and depression, especially in women, there were no consistent associations between masking measures and early autism identification.Conclusions: These findings suggest that while camouflaging behavior may exacerbate psychological distress and make autism more invisible for women, it is not the primary factor contributing to the delayed identification. Instead, gender stereotypes and the inadequacy of clinical assessment tools tailored to more typically feminine presentations of autism are likely major obstacles in the diagnostic process. Community Brief Why is this an important issue? Autistic traits are pivotal aspects of individuals' identities, yet they are frequently misunderstood, especially in girls and women. Recognizing and diagnosing autism in women are crucial for providing self-awareness and appropriate support, when necessary, and improving their quality of life. What was the purpose of this study? This study aimed to understand the characteristics of autism in adult Brazilian women, including how they might mask their traits and the challenges they face in obtaining a formal identification. What did we do? We conducted a survey involving 253 autistic adults and used several psychological assessment tools to collect data on stress, anxiety, depression, camouflage behaviors, autism-related characteristics, and the processes of suspicion and diagnosis. By comparing data from women with those of men and non-binary individuals, we aimed to provide a comprehensive understanding of autism across genders. What were the results of the study? Our research revealed that autism traits were relatively consistent across women, men, and non-binary individuals. However, women experienced more significant delays in receiving an autism diagnosis compared with other genders. It was notably more common for women to receive prior diagnoses of other psychological conditions before being identified as autistic, compared with men. Women frequently employ camouflaging behaviors more than men, but these behaviors do not appear to directly account for the delays in autism identification, although they are linked to increased feelings of anxiety, stress, and depression, especially among women. What do these findings add to what was already known? These findings highlight the complexity of identifying and diagnosing autism in women and challenge previous assumptions about the role of camouflage in diagnosis delays. The study emphasizes the need for improved awareness among health care professionals and more sensitive assessment tools to accurately identify autism in women. By addressing these challenges, we can ensure timely and accurate diagnoses, leading to better support and outcomes for autistic women. What are potential weaknesses in the study? While the study focused primarily on autistic women, its limitations provide insights into other overlooked populations. The small sample size for non-binary individuals limits the generalizability of the findings to this group. Future research should aim to include larger and more diverse samples to better understand the experiences of non-binary individuals on the autism spectrum. How will these findings help autistic adults now or in the future? In summary, this study contributes to a growing body of research aimed at improving the recognition and support of autistic individuals, particularly women, in Brazil and beyond. By raising awareness of the challenges women face in receiving an autism identification, we can pave the way for better support and understanding, ultimately enhancing the quality of life for all individuals on the autism spectrum.
