1. Questionnaires for ADHD diagnosis
Author: Ulrich Brennecke
Review: Dipl.-Psych. Waldemar Zdero (08/2024)
Questionnaires are filled out by people with ADHD themselves and their caregivers (parents, teachers, friends).
Questionnaires are very subjective and involve the risk that the respondent’s personal opinion about ADHD itself influences the response scale. It can happen that parents reject the diagnosis of ADHD in principle, especially in their own child. Likewise, subjective ideas of people with ADHD (perhaps that they “want” a diagnosis in the hope of finding a solution to their suffering, perhaps that they reject a diagnosis because they fundamentally reject ADHD or to avoid stigmatization) or the change in assessment standards due to intensive prior employment can distort the results (bias).
For example, in tests of elimination diets for ADHD, the results of parent surveys are always far more positive than the results of objective tests.1 As this occurs even in double-blind studies, there is a considerable bias on the part of parents to report the subjectively desired result (that ADHD can be treated with a diet rather than with critically considered medication).
However, it is also conceivable that the parents were already enthusiastic about the small improvements that an elimination diet can bring or that a placebo effect can have on the child with ADHD and were not even aware of the much better effect that could be achieved through medication or therapy, or at least were not aware of it at the time of the assessment.
The accuracy of clinical questionnaires should not be overestimated. Even very renowned standard tools should not be misunderstood as an objective benchmark.
A study of n = 76 diagnosed with ADHD from 19 to 63 years and unaffected individuals assigned to either a control group (N = 58, 18 to 73 years) or a simulation group (n = 46, 18 to 57 years) found:
- CAARS2
- Sensitivity in experimental simulators 24 % to 65 %
- Error rate for sample of people with ADHD 8 % and 34 %
- Specificity “perfect”
- SRSI (which was not developed for ADHD, but to assess overreporting of symptoms)2
- Sensitivity in experimental simulators 69 % to 82 %
- Error rate in sample of people with ADHD 33 % and 47 %
- Specificity 90 %
Sensitivity: People with ADHD are correctly recognized as people with ADHD
- Example: Sensitivity of 85 %: 15 % of the results are false negative. 15% of people with ADHD are incorrectly assessed as not having ADHD
Specificity: Non-ADHD persons are correctly recognized as non-ADHD persons
- Example: Specificity of 91 %: 9 % of the results are false positives. Of the subjects assessed as having ADHD, 9% are not actually affected
Kappa: Comparison of observed agreement between raters with the expected agreement in the case of random agreement (1 would be perfect)

1. Questionnaires, interviews, tests according to sensitivity and specificity
Sensitivity: People with ADHD are correctly recognized as people with ADHD
Specificity: Healthy people are correctly recognized as healthy people
AUC: Area under the curve; selectivity. 0.5 = chance; 1 = 100 % = perfect
- 0.6 - 0.7: poor
- 0.7 - 0.8: acceptable
- 0.8 - 0.9: good
- 0.9 - 1.0: excellent
A significance of 80 % and a specificity of 80 % are assumed to be appropriate values.3 These values are barely achieved by a single test for ADHD. A combination of several tests is therefore required to diagnose ADHD.
However, sensitivity and specificity are not the only relevant criteria for a questionnaire.
An exaggeration makes it clear: you could create a perfect questionnaire with just one question that, if answered truthfully, has a sensitivity of 100% and a specificity of 100%. The question is: “Do you have ADHD?”
This persiflage is intended to point out that the fewer questions are asked, the more these questions are on a meta-level and therefore much more difficult for the people with ADHD to answer than questions that are aimed at life facts, of which, however, more are needed for a reliable assessment in Consequences.
In a nutshell: We are very skeptical as to whether it is good for science that more and more studies on ADHD rely exclusively on self-report on the 6 questions of the ASRS, and we view this development with concern.

2. Clinical expert scales
Clinical expert scales:38
- IDA-R (Integrated Diagnostics of Adult ADHD, revised version)
- Standardized diagnostic guide that draws on existing instruments39
- Step 1: ASRS as screening
- Step 2: ADHD symptoms in childhood
- Unlike WURS-k, uses not only self-reporting, but also third-party anamnestic information
- IDA is based on the 5 ADHD core symptom items of the WURS-k with the highest discriminatory power (between 0.52 and 0.60):
- Concentration problems
- Fidgety/nervous
- Loss of self-control
- Low stamina
- Inattentive/dreamy
- Characteristics that indicate frequently occurring oppositional and emotional disorders in children and that show high discriminatory power values (0.53 to 0.61) are recorded by IDA but not included in the evaluation
- Strong mood swings/moody
- Disobedient/rebellious/rebellious
- Tendency to be or act unreasonably
- Cutoff39
- At 6 or higher: specificity of 85 % (15 % are detected although not given) and sensitivity of 91 % (9 % are incorrectly not detected) (recommended; is nevertheless stricter than WURS-K with more incorrect non-detection of child ADHD symptoms)
- At 7 or higher: specificity at over 99 % (1 % are detected although not given), sensitivity at 79 % (21 % are incorrectly not detected)
-
- Step: Diagnosis of acute symptoms according to DSM / ICD
- Semi-standardized interview
- Finding symptoms

- QbTest
3. Self-assessment questionnaires
A meta-study of 9 ADHD questionnaires found that only 37% asked identical symptoms/behaviors.55 Most of the questionnaires for children were answered by parents, most of the questionnaires for adults were self-tests.
In questionnaires, a study showed considerable deviations in the assessments of parents, teachers and people with ADHD, with the exception of emotional dysregulation, all existing symptoms, but even more so the frequency of their occurrence.56
In the case of self-assessment questionnaires, response tendencies and unintentional misjudgments can influence the result.
Subjects who were asked to report their daily physical activity showed considerable deviations from the actigraphy measurement, even though they were aware of the actigraphy measurement.57
Children with ADHD performed worse on tests with a slow event rate, while their results on exciting, challenging tasks were comparable to those of people with ADHD.58 59 It is consistent with this that the results of tests with people with ADHD change when rewards are promised.60 This also indicates that it is not the ability to concentrate or inhibition that is impaired per se, but rather the insufficient activation by “normally interesting” stimuli that is the actual key.
- Behavioral symptoms were asked from 28% to 81% of the questions in the questionnaires
- Cognitive symptoms were addressed by 9% to 44% of the questions
- Emotional symptoms accounted for between 0% and 24% of the questions
- Physical symptoms were only surveyed at all in 3 out of 9 instruments

In children already diagnosed with ADHD, was helpful in recognizing comorbidities:
A combination of two subscales of the CBCL, namely the Aggressive Behavior T-Score and the Delinquent Behavior T-Score, detected comorbidities in children with existing ADHD:94

- CBCL-DESR
Conversely, the Attention Problems Scale subscale of the Child Behavior Checklist (CBCL) showed a cut-off of 63:96 in the detection of ADHD in people with generalized anxiety disorder
- an AUC of 84 %
- 74% of adolescents with GAD and ADHD were above this cut-off (sensitivity)
- 91% of adolescents with GAD without ADHD were below this cut-off value (specificity)
The PTSD subscale of the CBCL can distinguish trauma well from non-affected and ADHD well from non-affected, but not PTSD from ADHD.97

7. Self-assessment skills
Adolescents with ADHD showed gender-specific abilities to assess their own symptomatology:100
Boys tended to ascribe too low symptoms to themselves, girls assessed themselves realistically.
Parents underestimated the symptoms of girls.
