Objective: The current study examines psychometric properties of the Weiss Functional Impairment Rating Scale (WFIRS), a measure of adult ADHD-related impairment. It is a self-report questionnaire that provides a metric of overall life impairment and domain-specific dysfunction. Method: Using data from a large (N = 2,093), multi-institution sample of college students and including a subsample of collateral informants (n = 262), a series of analyses were conducted. Results: The WFIRS…

TLDR
A brief parent and teacher rating scale for assessing impairment was developed and studied using attention deficit hyperactivity disorder as an exemplar disorder and was highly effective in discriminating between children with and without ADHD.

Validation of the Adult Attention-Deficit/Hyperactivity Disorder Quality-of-Life Scale (AAQoL): A Disease-Specific Quality-of-Life Measure
TLDR
The ability to quantify the quality-of-life consequences of adult ADHD should facilitate future research, assist clinicians in identifying appropriate treatment targets and contribute to the ultimate goal of improving the well-being and functioning of adults with ADHD.
Development of a New Psychosocial Treatment for Adult ADHD
TLDR
The findings indicate that participants in the MCT program showed marked improvement with respect to core ADHD symptoms of inattention, as well as executive functioning skills, suggesting that this program has promise as a treatment for meta-cognitive deficits in adults with ADHD.
When diagnosing ADHD in young adults emphasize informant reports, DSM items, and impairment.
TLDR
It is indicated that although a majority of young adults with a childhood diagnosis of ADHD continued to experience elevated ADHD symptoms and clinically significant impairment, only 9.7% of the childhood ADHD group continued to meet DSM-IV-TR criteria for ADHD in young adulthood.
The Range of Impaired Functioning Tool (LIFE-RIFT): a brief measure of functional impairment.
TLDR
This psychometric evaluation provides empirical support for the reliability and validity of the LIFE-RIFT, a brief measure of functional impairment, which showed that those in episode were significantly more impaired than those in recovery.

DSM-5 and Other Symptom Thresholds for ADHD: Which Is the Best Predictor of Impairment in College Students?
TLDR
The Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) threshold of five symptoms for ages 17 years and older is not necessarily predictive of ADHD-related impairment in college students and may not be preferable to other thresholds.

TLDR
Efforts are needed to increase the detection and treatment of adult ADHD and research is needed to determine whether effective treatment would reduce the onset, persistence, and severity of disorders that co-occur with adult ADHD.
