Spend some time on autistic social media and you will soon meet three letters: RSD, for rejection sensitive dysphoria. People use it to describe how a short reply, a frown or a piece of criticism can set off an emotional storm that feels physical, overwhelming and much bigger than the event itself.
In April 2026, three Dutch researchers published a scoping review on this topic in autistic adults, in the open-access journal Neurodiversity. Their conclusion is nuanced: the experience is real and can be very painful, but the science behind the label is still thin and scattered.
Rejection Sensitivity and RSD Are Not the Same Thing
Rejection sensitivity is a well-studied psychological concept. In 1996, the Columbia University psychologists Geraldine Downey and Scott Feldman described people who "anxiously expect, readily perceive, and overreact" to rejection, and developed a questionnaire to measure the anxious-expectation part. Their experiments showed that these people are quicker to see intentional rejection in ambiguous behaviour.
RSD is different. The term was introduced by the US psychiatrist William Dodson, based on his clinical experience with people with ADHD, and it spread mainly through social media. It is not a diagnosis in the DSM-5-TR or the ICD-11, the two reference manuals used by clinicians. Nor, as the review authors note, is it an established research construct, which is why the evidence is so scattered.
What the Review Did
Alvin van Asselt, Desiree Reekers and Yvette Roke, of the Dutch mental health organisation GGz Centraal, followed the PRISMA-ScR guidelines for scoping reviews. Because few studies use the term RSD, they looked more broadly at emotional, physical and physiological responses to rejection and criticism in autistic adults and in adults with high autistic traits. They searched peer-reviewed articles, conference papers and dissertations published up to May 2025.
Two authors independently screened 1,285 titles and abstracts, then 37 full texts. Only 12 studies met the criteria: four qualitative studies (interviews or written accounts), six experiments using tasks that simulate rejection, and two survey studies.
What It Found
- No shared definition: studies described and measured rejection-related distress in very different ways, which makes them hard to compare.
- Mixed results on intensity: some studies found stronger reactions to rejection in autistic adults than in non-autistic adults; others found weaker reactions or no clear difference.
- Links with mental health: several studies connected rejection-related distress with anxiety and depression.
- Consistent lived experience: in the interview studies, autistic participants consistently described rejection as very distressing.
- Big gaps: no study looked at responses to criticism, and none tested a way to reduce this distress.
The authors conclude that preliminary evidence suggests some autistic adults may experience profound responses to rejection, but that inconsistent findings and very different study designs prevent a clear picture. They call for a clearer definition of RSD and of its links with related ideas such as social pain, research on criticism and contributing factors, and support developed with autistic adults.
Why the Results Point in Different Directions
Two studies from the wider literature show how this can happen. In 2022, researchers found that people with high autistic traits felt more hurt after a simulated rejection, with stronger brain responses. In 2024, a study of 20 autistic and 40 non-autistic students found that autistic participants less often expected to be liked, yet across the whole group it was social anxiety, not autistic traits, that predicted expecting rejection.
Life history matters too. In a 2025 interview study by the same Dutch team, 19 autistic adults aged 21 to 71 who reported high rejection sensitivity described it as overwhelming and exhausting, sometimes with physical tension, pain and the reliving of past rejections. It was often dismissed, including by health professionals. Participants linked it both to autistic traits and to a lifetime of rejection: autistic people are at greater risk of social rejection than their peers.
What About ADHD and Alexithymia?
Research on RSD in ADHD is young too. A 2026 survey of 4,150 US college students found that ADHD symptoms and rejection sensitivity were positively related, while noting that earlier findings were mixed. Another 2026 study, of 666 women from the general population, found that both rejection sensitivity and alexithymia (difficulty identifying and describing one's own emotions) were linked with angry rumination. These are correlations, not causes, but they hint that having words for one's feelings matters.
A Useful Word, With Some Risks
In a 2026 reflection in the Dutch journal Tijdschrift voor Psychiatrie, Alvin van Asselt acknowledges that the term RSD can bring validation and a sense of connection. He also lists four risks: more stigma and self-stigma, presenting the problem as purely innate so that the social environment is overlooked, confusion between terms, and limited evidence. He suggests that professionals use the established concept of rejection sensitivity instead, and notes that less stigma and more inclusion could also help.
What This Means for You
If rejection hits you hard, the lack of an official label does not make your experience any less real. Here are some steps many people find helpful:
- Name the feeling: saying to yourself "this is a rejection wave" can create a little distance.
- Check your interpretation: a short reply or a silence can have many explanations, such as tiredness or a busy day. When it feels safe, asking directly often helps more than guessing.
- Let the peak pass: nothing has to be answered or decided while the emotion is at its strongest.
- Look at your surroundings: repeated real rejection shapes sensitivity. People and places that accept you as you are make a difference.
- Talk to a professional if it affects your relationships, work or mood, ideally someone who knows autism or ADHD. If you have dark thoughts, contact a doctor or a crisis line without waiting.
To see things more clearly, you can take our free rejection sensitive dysphoria test (RSD-12), 12 questions in about 4 minutes, or the shorter rejection sensitivity screener. For difficult moments, the free RSD First Aid Card suggests what to say to yourself and what to do in the twenty minutes after a perceived rejection. These tools are not a diagnosis, but they can help you put words on what you go through.
