ADHD Tests For Adults and Adolescents
There is no single test to determine whether someone is suffering from ADHD. To diagnose ADHD, healthcare professionals need to consider how symptoms impact daily functioning and rule out other physical and mental conditions that cause similar issues.
Specialists will also ask about your symptoms prior to age 12. According to current guidelines for diagnosing, to qualify for a diagnosis you must have suffered with these issues since childhood.

Conners Adults ADHD Rating Scales (CAARS)
In a clinical setting, rating scales are employed to differentiate adult patients with ADHD and those who do not exhibit symptoms. However, it can be difficult to achieve satisfactory distinction rates, particularly when patients with a variety of diagnoses show similar symptoms in the emotion regulation or impulse control domains. For example, anxiety disorders frequently co-occur with symptoms of impulsiveness or disinhibition. In these instances the use of rating scales could lead to an overdiagnosis or overtreatment.
To help address this problem, the original CAARS was updated in 1999 to include an observer form to enable an accurate assessment of the severity of a symptom. Numerous studies have investigated the psychometric properties of this revised version of the CAARS. Particularly the convergent and simultaneous validity of the measure has been found to be satisfactory (Smyth & Meier Citation 2019). Some criticisms have been made regarding the measure's sensitivity toward non-credible reports, which is a common issue in ADHD rating scales.
The CAARS-S:O was used in a variety of diagnostic conditions and clinical samples. The psychometric properties of the short self report and observer forms such as configural invariance and invariance of metric measurements were evaluated. These findings have placed considerable confidence in the ability of the instrument to detect ADHD symptomatology in adults.
In a recent study, the authors of the CAARS-S:O assessed the factor structure of this instrument in a sample of nonclinical adult patients using exploratory and confirmatory factor analysis. The results showed that the four-factor model matched to the data and was in line to previous research (Conners Erhardt Epstein et. and., Citation1999). The scalar-invariance of this model was also proved. In the end, the scalar and configural invariance was also confirmed by gender, allowing scores to be attributed to differences in underlying dimensions.
Recently adhd test for adult I Am Psychiatry of CAARS-S:O extended these findings to a nonclinical adult Japanese population. 786 participants completed both the CAARS S:S and CAARS Observer forms. The same four-factor model was found be valid in the North American population with satisfactory metrics invariance and configural invariance. This study extends the validation of the CAARS S:O to a new population and confirms its utility in identifying ADHD symptoms in emerging adulthood.
Barkley Adults ADHD Scales - IV (BAARSIV)
The BAARS-IV assesses current ADHD symptoms, domains of impairment and childhood symptoms. It is designed to provide an extensive examination of a person's functioning in all areas, such as school, social and work. It is easy to administer and takes approximately 5-7 minutes to complete. The BAARS-IV includes both self and other (i.e., spouse/partner or parent) report items. This improves the reliability of the test.
Compared to age-based norms The BAARS-IV identifies whether symptoms are "Clinically Significant," suggesting that the person is more noticeable than other people of the same age, and could require further investigation. A score of "Not Clinically Significant" means that the symptoms do not interfere with functioning and is more reflective of the typical range of people of the same age.
This study involved an average of 124 adults aged between the age of 18 and 67. They were physician- or self-referred to a medical center's outpatient clinic to evaluate ADHD. Every participant completed the BAARS IV SCT subscales and ADHD severity measures (self-report and other versions). Collateral reporters were spouses/partners or parents, friends or siblings. A total of 51 reports were taken.
The results prove the validity and reliability of a 3 factor model of SCT and demonstrate that it can be successfully utilized to determine the clinically meaningful distinctions between people with and without ADHD diagnosis. Additionally, SCT symptom severity is uniquely associated with endorsements of impairment in school, home, and community activity function by collateral reporters, even when they are controlled for ADHD symptoms.
These findings are part of an increasing body of literature that suggests SCT is an important and distinct concept that merits attention in adults presenting for evaluation of mental disorders. SCT symptoms are also reliably and validatedly assessed using the BAARS IV in the clinical setting and are associated with functional impairment. Further research is needed to determine the impact SCT can have on other aspects of life like stress in the home or psychopathology in offspring. SCT is a critical element in understanding and addressing the effects of ADHD in adulthood.
Behavior Rating Inventory of Executive Function Adult Version (BRIEF-A)
The BRIEF-A measures adult executive function. It includes 63 items from nine theoretically and empirically constructed and well-tested clinical scales that assess the most commonly accepted domains of executive functioning: Inhibit, Self-Monitor, Emotional Control, Shift Initiate, Working memory and Plan/Organize. It is available in self-report and informational versions and a form for parents/teachers as well. The test typically takes between 10 and 15 minutes to administer and 15-20 minutes to score. T-scores and percentiles can be calculated on the reverse of the summary sheet of scoring. The BRIEF can be used by adults as well as adolescents aged between 18 and 90. It is especially useful for those who suffer from academic, behavioral, or cognitive problems which are difficult to identify by other methods, such as autism or pervasive developmental disorders.
The instrument can be used in research and clinical settings by psychologists and neuropsychologists. It was standardized based on a sample of women and men ages 18-90, who were matched with 2002 US Census data. The normative sample was representative of the United States population in terms of race/ethnicity, educational background and geographic region. The Metacognition and Behavioral Regulation Indexes scales were standardized for self-reporting as well as informant reporting. Three validity scales (Negativity Inconsistency and Infrequency) were used to determine measurement accuracy.
In addition to providing standardization for individual scales, the BRIEF-A provides a the profile and baseline rates of scale elevation for several mental disorders, including ADHD, PTSD, depression schizophrenia spectrum disorders and TBI. (TBI). It also offers reliable change indexes for comparing symptom severity over time, for example after the administration of a medication.
The authors of BRIEF-A have published numerous papers on the application of this instrument to various psychiatric disorders, especially those that affect executive functioning. The instrument can also be utilized to study the effects of traumatic brain injuries as well as dementia, Tourette's Disorder and Parkinson's Disease. These studies showed that the BRIEF-A was a valid and reliable measure of executive functioning in daily life among these populations. This is especially applicable to the subscales of Inhibit and Emotional Control.

Many people suffering from ADHD are hesitant to seek treatment and diagnosis due to the stigma associated with the condition. If you're constantly losing your keys, have difficulty completing your work or your relationships suffer due to inattention, obtaining a proper diagnosis is the first thing to do. There's no need to undergo blood tests or brain scanning. Instead an expert will conduct a one-onone conversation and use rating scales to determine the impact of your symptoms on your daily life.
To get a fair assessment, your evaluator will be looking for details about your history--how you got through school, what your relationships are with your family and friends, what's going on at work, at home or at school, and more. You should be prepared to provide your medical information, like birth weight, milestones like the ability to walk or speak, hospitalizations, and ongoing health issues.
The SNAP-IV rating scale includes nine questions about inattention and nine about hyperactivity and impulsivity. In addition, you'll rate how often you have those symptoms. The SNAP-IV is an excellent indicator of whether you suffer from the inattentive or combined type of ADHD, and it can also help identify coexisting conditions like anxiety or depression.
You may be required to provide information on other people, particularly family members, as ADHD can be a problem that runs in families. A family history of ADHD can also indicate if you have the inattentive or impulsive-hyperactivity subtypes of ADHD.
Your evaluation can also include cognitive and neuropsychological tests. These tests aren't diagnostic, but they can give valuable information about how ADHD affects your memory, learning and thinking capabilities.
The Trail-Making Test measures your ability to switch between tasks and follow a series of letters or numbers. This test is suitable for adults and children of all ages and levels of skill and it can be used to screen for ADHD as well as other disorders that affect memory and learning.
