First Do No Harm: Ethical Issues in Pathologizing Normal Variations in Behavior and Functioning

Dyslexia in the twenty-first century: a commentary on the IDA definition of dyslexia

In offering a commentary upon the IDA definition, we address its main components in turn. While each is technically accurate, we argue that, when taken together, the definition, or more accurately, the use to which it is often put, becomes problematic. We outline different current conceptions of dyslexia and conclude that the operationalisation of the definition for diagnostic purposes often results in scientifically questionable diagnoses and inadvertently leads to significant educational inequity. We propose a simpler definition that describes the primary difficulty, avoids reference to causal explanation, unexpectedness, and secondary outcomes, and redirects practitioner and policymaker focus to the importance of addressing and meeting the needs of all struggling readers.

The Ability of Self-Report Methods to Accurately Diagnose Attention Deficit Hyperactivity Disorder: A Systematic Review

OBJECTIVE

To identify and analyze all studies validating rating scales or interview-based screeners commonly used to evaluate ADHD in adults.

METHOD

A systematic literature search identified all studies providing diagnostic accuracy statistics, including sensitivity and specificity, supplemented by relevant articles or test manuals referenced in reviewed manuscripts.

RESULTS

Only 20 published studies or manuals provided data regarding sensitivity and specificity when tasked with differentiating those with and without ADHD. While all screening measures have excellent ability to correctly classify non-ADHD individuals (with negative predictive values exceeding 96%), false positive rates were high. At best, positive predictive values in clinical samples reached 61%, but most fell below 20%.

CONCLUSION

Clinicians cannot rely on scales alone to diagnose ADHD and must undertake more rigorous evaluation of clients who screen positive. Furthermore, relevant classification statistics must be included in publications to help clinicians make statistically defensible decisions. Otherwise, clinicians risk inappropriately diagnosing ADHD.

Online search strategies utilized in feigning attention deficit/hyperactivity disorder (ADHD) while performing a continuous performance test (CPT)

BACKGROUND

The availability of information regarding neuropsychological tests threatens their confidentiality. This concern may be particularly relevant to Attention-Deficit/Hyperactivity Disorder (ADHD) considering its widespread online coverage. The present study explored simulators' online search strategies.

METHOD

Simulators (n = 39) searched for information before undergoing an evaluation which included performing a continuous performance test (CPT). Their search strategies were analyzed, and their performance was compared to that of ADHD patients (n = 36) and healthy controls (n = 38).

RESULTS

Most simulators reached high-risk websites that provided written and video-based information regarding the test. Sixty percent, comprised mostly of 3rd-year students, reached Google Scholar. These students were also easier to detect as simulators. Common strategies included performing the CPT in accordance with typical ADHD symptoms and avoiding the endorsement of both unusual and stereotypical symptoms.

CONCLUSION

Simulators can access online information that contains key test data. Higher education may increase the ability to reach academic research while decreasing the ability to convincingly feign impairment. While additional research is needed to examine coaching effects on neuropsychological testing, the risk to test security that many websites pose should be acknowledged and steps, including ones taken by test publishers, should be undertaken to minimize it.

Accommodation Decision-Making for Postsecondary Students with ADHD: Treating the Able as Disabled

Students with attention-deficit/hyperactivity disorder (ADHD) may be entitled to academic accommodations in postsecondary education. Disability Services Offices (DSOs) in Canada say that objective evidence of functional impairment is required prior to providing academic accommodations. This study set out to determine if postsecondary disability service providers use objective, third-party data when making accommodation decisions. Providers were asked if they would grant extra time accommodations to a fictitious prospective student. The student self-reported attention and academic problems that emerged during COVID restrictions, and that extra time helped her earn better grades and reduced her anxiety. While her neuropsychological report suggested superficial similarity to ADHD and contained accommodation recommendations, it lacked any objective evidence supporting either an ADHD diagnosis or functional impairments that would support extra time accommodation. Despite the lack of current or historical functional impairment, 100% of all DSO decision makers confirmed that they would grant extra time accommodations to this student. Results suggest that DSOs’ accommodation decisions are not based on evidence of functional impairment but rely mainly on student self-report and the recommendations of a professional. As such, the current system of determining reasonable accommodations is flawed and inequitable, offering non-impaired individuals access to supports and services that may privilege them over their similarly abled peers. Postsecondary institutions must either develop more defensible methods of disability determination or provide all students with access to accommodations to create a more equitable learning environment.
