What is the BRIEF-2? A guide to the Behavior Rating Inventory of Executive Function

The BRIEF-2 (Behavior Rating Inventory of Executive Function, Second Edition) is a standardized questionnaire rating scale that measures how well children and adolescents ages 5 to 18 manage everyday "executive function" behaviors, meaning the self-regulation skills involved in controlling impulses, shifting between activities, holding information in mind, and organizing work. Parents, teachers, and students themselves answer written items about behavior at home and school. The BRIEF-2 is a rating scale completed by observers, and it is neither a performance test nor an IQ test: the child never solves problems or completes tasks during the assessment. This article explains who developed the BRIEF-2, what its forms and scales contain, how its scores work, and how it fits alongside cognitive testing.

The BRIEF-2 was written by Gerard A. Gioia, Peter K. Isquith, Steven C. Guy, and Lauren Kenworthy and is published by PAR (Psychological Assessment Resources) in Lutz, Florida. The second edition appeared in 2015 as a revision of the original BRIEF, which the same author team published in 2000. According to PAR, the instrument is intended for children and adolescents for whom there are concerns about self-regulation, including those with autism spectrum disorder, learning disabilities, attention disorders, traumatic brain injury, depression, and other developmental, neurological, psychiatric, and medical conditions.

Three rating forms cover different informants. The Parent Form and Teacher Form each contain 63 items and cover ages 5 through 18. The Self-Report Form contains 55 items and is completed by adolescents ages 11 through 18. PAR lists administration time at about 10 minutes per form, with scoring handled digitally through its PARiConnect platform. A short 12-item Screening Form, taking roughly 5 minutes, is available for deciding whether a fuller assessment is warranted. Spanish-language Parent and Self-Report forms exist in print and digital formats. The BRIEF-2 is a B-level qualification product, which means purchasers need relevant graduate training or certification; it is not a consumer questionnaire.

The BRIEF-2 also sits within a family of related measures. The BRIEF-P covers preschool children ages 2 to 5, and the BRIEF2A extends the same three-factor model to adults ages 18 to 99, with self-ratings and ratings from people who know the adult well.

The Parent and Teacher forms score nine clinical scales: Inhibit, Self-Monitor, Shift, Emotional Control, Initiate, Working Memory, Plan/Organize, Task-Monitor, and Organization of Materials. The Self-Report Form scores seven parallel scales. Each scale reflects a specific slice of self-regulation as it shows up in daily life, such as whether a student can resist blurting out answers, adjust when plans change, or keep track of assignments. Readers who want more depth on the memory component can review what working memory is and why it matters for learning.

The scales combine into three broader index scores plus an overall composite:

• Behavior Regulation Index (BRI): the ability to control impulses and monitor one's own actions, built from the Inhibit and Self-Monitor scales.

• Emotion Regulation Index (ERI): the ability to shift flexibly and modulate emotional responses, built from the Shift and Emotional Control scales.

• Cognitive Regulation Index (CRI): the ability to initiate work, hold information in mind, plan, monitor progress, and stay organized, built from the remaining scales.

• Global Executive Composite (GEC): an overall summary score drawing on all clinical scales.

The BRIEF-2 also includes three embedded "validity scales" (Inconsistency, Negativity, and Infrequency) that help clinicians detect careless, exaggerated, or improbable response patterns. This matters because rating scales depend entirely on the honesty and accuracy of the person filling them out.

BRIEF-2 raw scores convert to "T scores," a standard metric with a mean of 50 and a standard deviation of 10, along with percentile ranks. Unlike IQ scores, where higher is better, higher BRIEF-2 scores signal greater difficulty. Following the interpretive guidance in the professional manual, researchers describe T scores of 60 to 64 as mildly elevated, 65 to 69 as potentially clinically elevated, and 70 or above as clinically elevated.

Scores are normed against a standardization sample so that a child's ratings can be compared with those of typical peers. The updated edition of the BRIEF-2 introduced age-based, combined-sex norms as a validated scoring option alongside the original age-and-sex-based norms, and PAR reports that score reports can be regenerated under either norm set. The publisher has also integrated its ADHD evaluation content, including profiles and classification statistics, directly into the professional manual and computer-generated reports rather than selling a separate ADHD form.

A useful caution applies to the scale scores. In a study of 5,212 clinically referred youth published in The Clinical Neuropsychologist, Jacobson and colleagues found that item-level factor analysis supported fewer distinct dimensions than the nine published scales, and they concluded that interpretation may be more defensible at the index level than at the individual scale level. Careful clinicians treat the index scores and composite as the sturdiest numbers and read individual scales as finer-grained hypotheses rather than firm conclusions.

The BRIEF-2 and an IQ test answer different questions. An IQ test asks a child to perform: solve matrix puzzles, define words, repeat digit strings, and so on, under standardized conditions, producing a measure of cognitive ability. The BRIEF-2 asks an observer to describe: how often does this child actually forget instructions, lose materials, or melt down when routines change? A child can score well on cognitive tasks in a quiet testing room yet struggle badly with organization and self-control in a noisy classroom, and the reverse also occurs. Research reviews have repeatedly found only modest correlations between EF ratings and performance-based executive tasks, which is why evaluators often use both.

Performance-based executive function batteries such as the D-KEFS measure executive skills through direct tasks, while the BRIEF-2 captures real-world behavior over weeks and months of observation. Broad-band behavior questionnaires such as the BASC-3 survey a wide range of emotional and behavioral functioning, whereas the BRIEF-2 concentrates specifically on executive function. In a comprehensive evaluation, a psychologist may combine an IQ test, achievement testing, performance-based executive measures, and rating scales like the BRIEF-2 to build a complete picture.

The BRIEF-2 has clear strengths. PAR reports that the BRIEF family is supported by 25 years of research and more than 2,000 peer-reviewed publications, with documented sensitivity in groups such as ADHD, autism, and traumatic brain injury. Multiple informants, built-in validity checks, and quick administration make it practical for schools and clinics, and its focus on everyday behavior captures information no laboratory task can.

Honest limitations matter just as much. Ratings reflect the rater's perspective, standards, and tolerance, so parent and teacher scores for the same child frequently disagree, and disagreement itself must be interpreted. Elevated scores describe behavior; they do not establish why the behavior occurs. The BRIEF-2 does not diagnose ADHD, autism, or any other condition on its own. Diagnosis requires a qualified clinician who integrates history, interviews, direct testing, and observation, and no single questionnaire or online test can screen for or detect a condition by itself. Finally, as the factor-analytic research above suggests, the nine-scale structure is better treated as a clinical convenience than as nine independently measured abilities.

The BRIEF-2 tells you how a young person's self-regulation looks in daily life. It does not tell you how strong their reasoning ability is, which is the job of a cognitive test. Adults who want a rigorous measure of their own cognitive abilities can take the RIOT IQ test, the Reasoning and Intelligence Online Test, developed by RIOT IQ with psychometrician Dr. Russell T. Warne. It includes 15 subtests across six cognitive indices (verbal reasoning, fluid reasoning, spatial ability, working memory, processing speed, and reaction time), takes about 52 minutes, and reports scores on the familiar mean-100, standard-deviation-15 scale. Like any online measure, it complements rather than replaces an individually administered diagnostic evaluation.

No. The BRIEF-2 is a questionnaire about everyday self-regulation behaviors completed by parents, teachers, or the adolescent. It involves no problem-solving tasks and produces no IQ score.

The Parent and Teacher forms cover ages 5 through 18; the Self-Report Form covers ages 11 through 18. The BRIEF-P covers ages 2 to 5, and the BRIEF2A covers adults 18 to 99.

According to PAR, each form takes about 10 minutes to complete, and the 12-item Screening Form takes about 5 minutes. Scoring is done digitally through PARiConnect.

BRIEF-2 results are reported as T scores with a mean of 50. Scores of 60 to 64 are considered mildly elevated, 65 to 69 potentially clinically elevated, and 70 or above clinically elevated, with higher scores indicating greater difficulty.

No single rating scale can diagnose any condition. The BRIEF-2 contributes evidence about executive function behavior, and PAR has integrated ADHD-related profiles into its reports, but diagnosis belongs to qualified clinicians who combine multiple sources of information.

PAR lists it as a B-level qualification product, generally requiring graduate training in psychological assessment or an appropriate certification, so it is used by psychologists, school psychologists, and similarly trained professionals.
