Module 3 — SAAST — A Longer, Structured Look at Adult ADHD

What twenty-two questions reach that six cannot, why length is not the same thing as accuracy, the requirements a total score can never satisfy, and why four of the questions on this screener are deliberately not scored at all.

The big idea

If you have ever finished a six-question quiz and thought "that was not enough to go on" — you were right, and you are about to meet the opposite problem. This module is about a twenty-two item questionnaire, what the extra sixteen questions buy you, and what no number of questions can settle.

A high SAAST score is a good reason to book an appointment. It is not a result. The instrument cannot see your childhood, your other settings, your sleep, your thyroid or the last two years of your life, and it does not claim to.

Step 1 — The lesson

A. Twenty-two questions instead of six

Module 2 of this course is about six questions. The World Health Organization started with eighteen, ran them against clinical assessment, and kept the six that separated people best. Narrow, tested, deliberately so.

The SAAST is not that. Twenty-two questions, five to seven minutes, and the extra items are not there to sharpen the screen. They are there to widen it — to reach the parts of an ADHD-shaped life a short symptom count leaves out. The direct debit that lapsed. The washing that got as far as the machine and stayed there. The conversation you left three sentences ago.

Breadth matters because of who tends to be reading a page like this. Adult ADHD averages 2.8 per cent across twenty representative surveys covering 26,744 people, and the same work calls it vastly under-recognised and undertreated, with help-seeking aimed mainly at whatever came along with it rather than at the ADHD itself.¹ Most people do not arrive because a symptom list matched. They arrive because a life stopped adding up.

Diagram — A · What length buys you. More items means more surface area, not more proof. A longer questionnaire asks about more of your week; it does not know more about you. Instruments of this kind are routinely sold as though those were one thing.

Here is that with numbers on it. A systematic review of every adult ADHD rating scale and interview screener with published accuracy data — twenty studies — found the same shape everywhere. Negative predictive values above 96 per cent. Positive predictive values peaking at 61 per cent in clinical samples, with most falling below 20 per cent. The authors conclude that clinicians cannot rely on scales alone and must evaluate anyone who screens positive more rigorously.²

Adding items does not move those numbers. It changes what gets asked about, not how much the answer settles. Read the SAAST as a wider net rather than a finer one. What it is good at is handing you the language and the examples for a conversation you may have been putting off for years.

B. The gates a score cannot open

A diagnosis of ADHD in an adult is not a score. It is several separate conditions that all have to hold at the same time.

From seventeen years old, five symptoms rather than six in at least one of the two lists. Several of those signs present before the age of twelve. Difficulties in more than one setting, not only in the hard one. And genuine interference — at home, at work or school, in relationships — rather than traits you can describe.³ A clinician then has to satisfy themselves that nothing else explains the picture better.

Diagram — B · What a total can carry. A score is an addition machine. The requirements above the line add up cleanly; the ones below it are gates, either open or shut. You cannot pay for a shut gate with a higher total, which is why the interesting part of this instrument sits outside the sum.

The age-twelve gate is the one adults find hardest, and the research says it is hard for everyone, not just for you. Ninety-four children who met full criteria for ADHD between the ages of seven and eleven were reassessed between sixteen and twenty-two, alongside their parents, against what had actually been recorded at the time. Both the young people and their parents had limited ability to recall their childhood symptoms accurately. Recall was also bent by the present: when current symptoms were endorsed, childhood symptoms were more likely to be remembered as clinically significant.⁴

That cuts both ways. Struggling now makes you likelier to remember struggling then; doing well now makes real childhood difficulty easier to write off as ordinary. Neither is dishonesty. It is how memory works in everybody, and it is why a careful assessment goes looking for evidence that did not come out of your own head — school reports, a parent, an older sibling.

There is also a documented pattern in who never got looked at. Clinical referral ratios for ADHD have run from 3 to 1 up to 16 to 1 in favour of boys, against a community ratio of around 3 to 1 — a gap an expert consensus statement attributes partly to lack of recognition and referral bias. Inattentive presentation is more common in girls and its symptoms are described as less obvious and therefore less likely to be detected, while compensatory behaviour — socially adaptive behaviour, compliance, coping strategies that mask — is named as a further reason the referral never happens.⁵ If you are a woman in your thirties reading a screener for the first time, you are the documented pattern rather than an anomaly.

C. Executive difficulty is not a fingerprint

Peel the word ADHD off the top of these twenty-two questions and what is left describes trouble with executive function: starting, switching, holding something in mind, stopping. That difficulty is real and measurable. It is also nowhere near specific.

A review bridging the clinical and cognitive literatures set the meta-analytic effect sizes beside one another. ADHD: shifting d = 0.55, inhibition d = 0.30, working memory d = 0.54 to 0.66. Mood disorders: shifting d = 0.46 to 0.71, inhibition d = 0.58 to 0.69. PTSD: shifting d = 0.70. Obsessive-compulsive disorder: updating d = 0.71. Schizophrenia, larger than all of them, d = 0.83 to 1.28. The authors describe executive function deficits as transdiagnostic.⁶

Read the ADHD row against the others. It is not the highest one on the page.

Diagram — C · One reading, many roads. This is the single most important caveat in the module. A high score is a fact about your week and a real one. It is not evidence for one explanation over the eight others that produce the same reading.

Sleep belongs on that list and is the one people discount fastest. A review of sleep disturbance in ADHD states plainly that sleep problems can lead to the development of ADHD or ADHD-like symptoms and potentially to misdiagnosis, and that the effects of restricted, disordered or disturbed sleep can manifest as symptoms, behaviours or functional impairments remarkably similar to those of ADHD; it puts sleep disturbance among people who do have ADHD at 25 to 55 per cent.⁷ Two years of broken nights will fill this questionnaire in for you.

Autistic burnout does the same thing and is much less well known. The community-partnered study that defined it — nineteen interviews plus nineteen social media sources — describes burnout as resulting from chronic life stress and a mismatch of expectations and abilities without adequate supports, characterised by pervasive, long-term exhaustion of typically three months or more, loss of function, and reduced tolerance to stimulus. Participants reported loss of executive functioning, loss of life skills, poor memory and problems with speech.⁸ Fill this in from inside burnout and it will read as ADHD.

Physical health earns a place too, though a smaller one than the internet gives it. A 2025 meta-analysis of eleven studies covering 1,190,059 people found overt hypothyroidism associated with a raised risk of cognitive impairment, odds ratio 1.18 (95% CI 1.04 to 1.34).⁹ That is a modest effect in mostly older samples. Thyroid function is on the list because it is cheap to check, not because it is likely.

None of this means your answers were wrong. It means the reading is shared. As many as 80 per cent of adults with ADHD have at least one coexisting psychiatric disorder, most often mood, anxiety, substance use and personality disorders, and the overlapping symptoms are a recognised challenge for diagnosis and treatment.¹⁰ The question is rarely ADHD or depression. It is usually which, how much, and in which order.

D. What this number is, honestly

The SAAST is New Path's own instrument. We wrote it. It has no published validation, no normative sample, no reliability coefficients, no factor analysis and no peer-reviewed psychometrics. We went looking before writing this module, on the assumption that we might be wrong about our own screener: a search of PubMed for the Structured Adult ADHD Self-Test returns zero records.

The live screener gives a total between 0 and 54 and splits it in exactly one place. A score of 0 to 24 is labelled Low or No ADHD Traits: "Your responses suggest you likely manage focus, planning, and impulse control within typical ranges. ADHD is unlikely to be a major factor in your day-to-day functioning." A score of 25 to 54 is labelled High ADHD Traits: "Your responses reflect a high number of ADHD-related traits that may significantly impact your ability to manage daily tasks, maintain attention, or follow through."

Diagram — D · The two bands. One line, one band either side, nothing in between. A 24 and a 25 are reported as different kinds of result. They are one point apart on an unvalidated scale, which is a difference you can feel free to ignore.

Two things about that split deserve saying out loud. There is no middle band, so the instrument cannot tell you it is unsure, and plenty of people land where unsure is the only honest answer. And the line at 25 is a design decision, not a measured cut-point: no study established it, no sample calibrated it, and it has never been checked against a diagnostic interview.

There is also a discrepancy we would rather flag than tidy away. Our own internal record of this screener lists the total as 0 to 60, while the live page states 0 to 54. This module follows the live page, because that is what you will see. The page does not state what response scale each item uses either, and we are not going to reverse-engineer one and present the guess as a fact.

Now the arithmetic that makes any single line weak. If roughly 2.8 per cent of adults have ADHD,¹ then of every hundred people who cross a threshold like this one, most will not have ADHD — not because the questionnaire is badly written, but because the condition is uncommon and the experiences it asks about are not. That is the mechanism behind positive predictive values mostly below 20 per cent and negative predictive values above 96 per cent in instruments with far better evidence than this one.² The low band is the trustworthy end.

The surrounding information environment does not help. When researchers rated the hundred most popular TikTok videos about ADHD, 52 were classified as misleading, 27 as personal experience and 21 as useful.¹¹ A questionnaire read in that context gets treated as a verdict, which is precisely what it is not.

Which brings us to the most unusual feature of this screener, and the one we would defend. Items 19 to 22 are not scored at all. They are read. The live page says they are reviewed qualitatively, to help judge whether ADHD is a plausible explanation for what the rest of the answers describe.

That is a defensible choice. A total is an addition machine, and the requirements that decide an ADHD diagnosis are not additive. Folding a question about childhood, or a second setting, or actual impairment into the sum would let a strong answer on one of them buy its way past a weak symptom count, which is not how the criteria work. Keeping those four outside the arithmetic is the instrument declining to trade a gate for a point. It is the same instinct behind Part B of the ASRS in Module 2: twelve questions carrying no total, kept because they give a clinician more to ask about.

The cost is obvious once you say it. A qualitative review needs somebody to do the reviewing. Four questions that nobody reads produce nothing, there is no rule for weighing them, and no two readers will weigh them identically. Look only at the number and the best-designed part of this screener is the part you have thrown away.

INSIDE THE INSTRUMENT

SAAST — Structured Adult ADHD Self-Test (New Path)

Where it came from

Built in-house by New Path for our own screening site. There is no development paper, no derivation sample, no published item-selection procedure and no author list. It was written to give adults a structured way to describe difficulties they were already having, and to give a first appointment somewhere concrete to start.

What it is made of

Twenty-two items. The live page reports a total range of 0 to 54 and states that items 19 to 22 are not scored, being reviewed qualitatively instead. The per-item response scale is not stated on the page and has not been inferred here. Two total bands only: 0-24 Low or No ADHD Traits and 25-54 High ADHD Traits. No subscales, no domain scores, no severity gradient. Our internal record lists the total range as 0 to 60; this module follows the live page and the discrepancy is flagged for correction.

How well it performs

Unknown, in the strict sense. No sensitivity, specificity, predictive value, internal consistency, test-retest reliability or factor structure has been published or computed, and a PubMed search for the instrument name returns no records. For the standard it would have to meet: a systematic review of adult ADHD self-report scales and interview screeners with published accuracy data found negative predictive values above 96%, positive predictive values peaking at 61% in clinical samples with most below 20%, and concluded that clinicians cannot rely on scales alone.² This one has not been measured at all.

Where it was validated

Nowhere. It has not been normed, standardised, translated, or compared against a structured diagnostic interview or clinician diagnosis in any sample. Scores are raw and are not comparable to any published cut-off.

What it cannot do

It cannot establish a single DSM-5 requirement. Five symptoms from seventeen years of age, several signs present before age 12, difficulties in more than one setting, genuine interference with functioning, and no better explanation elsewhere — the questionnaire touches none of these in its total.³ The design acknowledges this by moving four items out of the score entirely.

It cannot separate ADHD from the rest of the executive-function field. Meta-analytic deficits of comparable or larger size are documented in mood disorders, PTSD, OCD and schizophrenia;⁶ disordered sleep produces symptoms described as remarkably similar to ADHD;⁷ autistic burnout is characterised in first-person accounts by loss of executive functioning and poor memory;⁸ and overt hypothyroidism carries a modest raised risk of cognitive impairment.⁹

It cannot correct for retrospective recall. In a prospective sample of 94 children with DSM-IV ADHD reassessed at 16 to 22, both the young people and their parents recalled childhood symptoms poorly, and recall was biased by current symptom endorsement.⁴ Any self-report item about childhood inherits that bias.

It has no validity, effort or inconsistency scale and no mechanism for detecting careless, exaggerated or minimised responding. Nothing in it distinguishes a considered answer from a fast one.

Its cut-point is not a cut-point. The line at 25 was set by design, not calibrated against any criterion, and a single boundary forces every result into one of two categories with no way to report uncertainty.

What a clinician does with it

Use it as a structured interview schedule, not as a score. Read items 19 to 22 first, then the endorsed items, then the total, in that order. Follow with a developmental history reaching before age 12, collateral or documentary information wherever it can be obtained, evidence of difficulty in more than one setting, documented functional impairment, and a differential covering mood, anxiety, trauma, substance use, sleep and relevant physical health. As many as 80% of adults with ADHD carry at least one coexisting psychiatric diagnosis, so the task is rarely either/or.¹⁰ A European consensus statement concludes that adult ADHD is often a lifelong impairing condition and remains underdiagnosed and undertreated in many countries — which is the reason to take a positive screen seriously, not the reason to accept it.¹²

Validity tier: 4 — built in-house by New Path. Honest and useful, not normed, no published validation. The construct it describes is well evidenced and the DSM-5 framework behind it is not in dispute; the instrument that describes it here has never been tested, and no number it produces should be treated as though it had.

Diagram — E · Where the screen actually sits. Nothing in the top row settles anything. The questionnaire exists to get you into a conversation with enough detail to make it efficient. The useful thing to do with a result is carry it downward, not treat it as an endpoint.

STRENGTHS LENS

You have been running a full assessment on yourself for years, without the paperwork.

Nobody sits down with a twenty-two item questionnaire about their own attention on a whim. By the time an adult gets here they have usually been gathering evidence quietly for a decade — noticing which jobs went well and why, working out that mornings need three alarms rather than one, building workarounds so elaborate that nobody around them ever saw a problem. That is a long piece of unaided self-observation, and it is exactly the raw material a good assessment runs on.

It is worth knowing what happens at the other end, too. When twenty-one adults diagnosed with ADHD in adulthood were interviewed about the consequences, positive experiences were dominant, though the picture was genuinely mixed: the diagnosis was described as an answer to many years of wondering and a source of self-knowledge, alongside real concerns about identity and stigma.¹³ An answer is not the same as a cure, and it is still worth having.

F. What helps

Five things worth doing with a longer questionnaire that a shorter one would not have given you.

1. Read the last four questions before you read the number.

Items 19 to 22 are kept out of your total by design. They ask about context rather than frequency, and they are the part a clinician actually wants. Write your answers to those four out in full sentences before you look at the score, so the number does not colour them.

2. Borrow somebody else's memory, deliberately.

Pick one person who knew you before you were twelve and one who lives alongside you now, and ask each the same two or three questions from the screener. Your own recall of childhood is documented as unreliable, and bent by how you are doing today. Two outside accounts beat an hour of trying harder to remember.

3. Write the two settings down separately.

One page for work or study, one for home, money and admin, a third for relationships if it applies. The requirement is difficulty in more than one setting, and people routinely under-report the setting they have adapted to best. Two thin pages are more useful to bring than one long complaint.

4. Give the other explanations a fair hearing first, not last.

Sleep, mood, anxiety, trauma, thyroid function, burnout. Working through these does not weaken your case — it is the same list a good assessor uses, and arriving having thought about it saves an appointment. Several of them are treatable in their own right, and several travel alongside ADHD rather than instead of it.

5. Take it to a person rather than to a feed.

Of the hundred most popular TikTok videos about ADHD, just over half were rated misleading.¹¹ An algorithm is very good at showing you more of what you just watched, which feels like confirmation and is not. Write your answers out and give them to somebody whose job it is to disagree with you if the evidence points that way.

Step 2 — Take the screener

Twenty-two questions, five to seven minutes, free and confidential. You get a total between 0 and 54 and one of two bands — and four of the questions are not scored at all, but reviewed on their own terms. Read section D before you read your number: the line between the bands was drawn by design rather than measured, and knowing that in advance keeps the result the right size.

Take the SAAST

Before you start

The SAAST is New Path's own instrument. It was built in-house, and it has no published validation, no normative sample, no reliability figures and no peer-reviewed psychometrics — a search of PubMed for it returns nothing. Its scores are raw, not standardised, and not comparable to any published cut-off, and the single line between its two bands was set by design rather than calibrated against any diagnostic interview. Executive-function difficulty is also strongly non-specific: it is documented in depression, anxiety, PTSD, disrupted sleep, autistic burnout and thyroid disease as well as ADHD, so a high score does not indicate that you have ADHD. This is a structured way to describe your own difficulties and start a conversation, not a diagnosis, and only a clinician can diagnose.

Step 3 — Your workbook

Your answers save to this device only — we cannot see a word of what you write. This module records your total, then does the work the total cannot: the four unscored questions, the childhood evidence, the second setting, and the other explanations worth ruling in or out first.

Your SAAST results

Took the screener? Put your total in below. Entirely optional — skip it if you would rather just read. Remember that items 19-22 are not in this number at all.

Score bands: 0-24 = Low or No ADHD Traits; 25-54 = High ADHD Traits

Fields: SAAST · Structured Adult ADHD Self-Test · 22 items; Total score (0-54); My total (enter 0-54); Date I took it

The four that are not counted

Section F, item 1. Items 19-22 sit outside the total on purpose. Write them out properly here, before the number gets a chance to colour them.

Fields: What I said in the last four questions, in full sentences; Did I read the number first?: No, I answered these first / Yes, I saw the score first / I have not taken it yet

Before twelve

The age-12 requirement is the one adult memory is worst at. Collect evidence that does not come out of your own head.

Fields: Tick: School reports or old report cards I could find; Tick: A parent, older sibling or relative who remembers; Tick: Anything a teacher wrote or said that stuck; What I remember myself, in whatever order it arrives

Two outside accounts

Section F, item 2. One person who knew you before twelve, one who lives alongside you now. Ask them the same few questions and write down what they said, not what you expected.

Fields: Person who knew me then; Person who sees me now; What they actually said

More than one setting

Section F, item 3. Separate pages, not one long list. People under-report the setting they have adapted to best.

Fields: Work or study; Home, money, admin; Relationships; Which setting am I most likely to be underselling?: Work or study / Home, money, admin / Relationships / Honestly, all of them

What else could explain this

Section F, item 4. Section C is the honest one. Going through this list makes an assessment faster, not weaker.

Fields: Tick: I have been sleeping badly for a long time; Tick: I am low or anxious most days; Tick: Something significant happened that I have not fully dealt with; Tick: I am autistic, or wonder whether I am, and I am running on empty; Tick: There is a physical health thing nobody has checked; Notes on any I ticked

The evidence you already gathered

Strengths Lens. Before any questionnaire existed, you were already working this out. Write down what you had figured out on your own.

Fields: Workarounds I built without being told to; The one thing I would want a clinician to understand first

View the paper Twenty nationally or regionally representative surveys administering the Composite International Diagnostic Interview to 26,744 adults across high-, upper-middle- and low/lower-middle-income countries, with a 68.5% mean response rate. Current DSM-IV adult ADHD prevalence averaged 2.8%, ranging from 3.6% in high-income to 1.4% in low/lower-middle-income countries, and current ADHD was present in 57.0% of childhood cases and 41.1% of childhood subthreshold cases. Adult ADHD was highly comorbid with anxiety, mood, behaviour and substance disorders and independently associated with role impairment, yet treatment seeking was low everywhere and directed mainly at comorbid conditions, leading the authors to describe it as vastly under-recognised and undertreated. Limitation: DSM-IV criteria and lay-administered interviews, so the 2.8% figure is not directly comparable to DSM-5 prevalence estimates.

View the paper Systematic review of adult ADHD rating scales and interview screeners, of which only 20 studies reported usable sensitivity and specificity data. Negative predictive values exceeded 96% across measures, while positive predictive values peaked at 61% in clinical samples and most fell below 20%, with high false-positive rates throughout. The authors conclude that clinicians cannot rely on scales alone to diagnose ADHD and must undertake more rigorous evaluation of anyone who screens positive. Limitation: samples, base rates and reference standards varied widely across the included studies, so the reported range is indicative rather than a pooled estimate.

View the paper Review of the bidirectional relationship between sleep and ADHD. It reports the prevalence of sleep disturbance in people with ADHD at 25 to 55%, with one Australian study finding 62% of children with ADHD had moderate or severe sleep problems, and states that problems with sleep can also lead to the development of ADHD or ADHD-like symptoms, potentially resulting in misdiagnosis. It further states that the effects of restricted, disordered or disturbed sleep can manifest as symptoms, behaviours or functional impairments remarkably similar to those of ADHD. Limitation: a narrative review weighted towards paediatric samples, with no pooled effect sizes and no direct test of how often adult ADHD screening positives are attributable to sleep.

DOI 10.1186/s12888-017-1463-3. View the paper Review of comorbidity in adult ADHD arguing for a dimensional rather than categorical approach to assessment and treatment. It reports that as many as 80% of adults with ADHD have at least one coexisting psychiatric disorder, most frequently mood and anxiety disorders, substance use disorders and personality disorders, and that the overlapping symptoms between ADHD and these comorbid conditions represent challenges for diagnosis and treatment. It also notes that emotional dysregulation is a distinctive feature of adult ADHD that may be misdiagnosed as a mood disorder. Limitation: a narrative review rather than a meta-analysis, and the 80% figure is drawn from clinical rather than community samples, so it overstates comorbidity in the general adult population.

View the paper Longitudinal study of 94 participants who all met full DSM-IV criteria for ADHD when first assessed between ages 7 and 11 and were reassessed between 16 and 22, using clinical interviews and ADHD checklists at both points. Both the young people and their parents showed limited retrospective recall of childhood symptoms against the contemporaneous records, and accuracy of recall was influenced by current symptoms: when current symptoms were endorsed, participants were more likely to recall clinically significant childhood ADHD symptoms. This is direct evidence that the DSM age-of-onset requirement cannot be settled by adult self-report alone. Limitation: a single clinically referred ADHD cohort with no non-ADHD comparison group, so it establishes recall inaccuracy in this population rather than quantifying it in the general adult population.

The ADHD effect sizes are not the largest in the set, which is the central point for anyone reading a raised score on an executive-function questionnaire.

Overt hypothyroidism was associated with an increased risk of cognitive impairment overall (OR 1.18, 95% CI 1.04 to 1.34) and of mild cognitive impairment specifically (OR 1.24, 95% CI 1.13 to 1.36), but not with Alzheimer's disease (OR 1.03, 95% CI 0.77 to 1.38) or all-cause dementia (OR 1.20, 95% CI 0.94 to 1.53). The authors state that the association still requires high-quality prospective studies for final confirmation. Limitation: the pooled cohorts skew older than the adults who take ADHD screeners, and the outcome is cognitive impairment rather than the attention and organisation difficulties an ADHD questionnaire asks about.

Clinical frameworks and position statements

3. Immanuel J, Burden J (2025). What is ADHD?. American Psychiatric Association, Patients and Families resource, reviewed October 2025. View the source Physician-reviewed public statement of the DSM-5 criteria from the association that publishes the manual. It records that a diagnosis requires six symptoms, or five for individuals who are 17 years old or older, that the symptoms must be present before the individual is 12 years old and must have caused difficulties in more than one setting, and that they lead to significant suffering and impairment at home, at school or work, and in relationships. It also states that several conditions can mimic ADHD and that a full psychiatric evaluation and careful history taking are very important. Limitation: a summary written for patients and families rather than the criteria text itself, so it paraphrases rather than reproduces DSM-5 wording.

View the source Consensus statement of the European Network Adult ADHD addressing clinical presentation in adults, diagnostic approach and treatment. It concludes that ADHD is among the most common psychiatric disorders of childhood, that it often persists into adulthood and old age as a lifelong impairing condition, and that it remains underdiagnosed and undertreated in many European countries, calling for improved professional education and a lifespan perspective. Limitation: expert consensus rather than a systematic evidence review, developed with a European focus and without formal grading of the evidence behind each recommendation.

View the source Expert consensus statement from the UK ADHD Partnership on identification and treatment of ADHD in girls and women across the lifespan. It records clinical referral ratios ranging from 3 to 1 up to 16 to 1 in favour of boys against a community ratio of around 3 to 1, and attributes the discrepancy at least in part to lack of recognition and referral bias in females. It notes a greater prevalence of inattentive presentation in girls whose symptoms are less obvious and therefore less likely to be detected, and identifies compensatory behaviours such as socially adaptive behaviour, compliance and coping strategies that mask difficulty as further barriers to referral. Limitation: expert consensus rather than a systematic review or meta-analysis, so the ratios are drawn from a heterogeneous literature and are not pooled estimates.

Positive experiences were dominant, though with complex variation both within and between individuals: the diagnosis was described as an answer to many years of wondering and a source of self-knowledge and increased personal value, alongside concerns about identity, potential stigmatisation and restricted life possibilities. It is included because it describes what actually happens after the questionnaire stage, which no psychometric paper reports. Limitation: 21 participants from one Swedish clinical setting, self-selected and interviewed at a single time point, so the balance of positive to negative experience is not generalisable.

Having all of your internal resources exhausted beyond measure and being left with no clean-up crew: defining autistic burnout. Autism in Adulthood, 2(2), 132-143. DOI 10.1089/aut.2019.0079. View the source Community-partnered qualitative study using 19 interviews plus 19 public social media sources, analysed thematically with a hybrid inductive-deductive approach. The resulting definition describes autistic burnout as a syndrome resulting from chronic life stress and a mismatch of expectations and abilities without adequate supports, characterised by pervasive long-term exhaustion of typically three months or more, loss of function, and reduced tolerance to stimulus. Participants specifically described loss of executive functioning, loss of life skills, poor memory and problems with speech, and the authors argue burnout is distinct from depression despite superficial similarities. Limitation: a small purposive sample recruited largely online, with no quantitative measure and no comparison against ADHD or depression samples, so it defines the construct rather than establishing how often it is mistaken for ADHD.

DOI 10.1177/07067437221082854. View the paper Cross-sectional content analysis of the 100 most popular TikTok videos about ADHD, classified as misleading, useful or personal experience and rated with the PEMAT-A/V instrument and JAMA benchmark criteria. Of the 100 videos meeting inclusion criteria, 52 were classified as misleading, 27 as personal experience and 21 as useful. This is the information environment in which most people now read a free online ADHD screener. Limitation: a snapshot of one platform at one point in time, with classification by a small number of raters and no measure of what viewers actually believed or did afterwards.

A longer questionnaire still needs a person. This course was built by clinicians who are part of the New Path family of therapy centers. The four unscored questions on this screener are exactly the kind of thing that is easier to think through out loud with someone than alone on a form. Therapy for clients in California, coaching worldwide, all by telehealth. A conversation costs nothing and there is no pressure. Saving this for later counts too. Talk with the New Path team
