Abbreviations: ADHD, attention-deficit/hyperactivity disorder; ASRS, Adult ADHD Self-Report Scale; AUC, area under the curve; NCS-R, National Comorbidity Survey Replication; NYU Langone, New York University Langone Medical Center Adult ADHD Program; PPV, positive predictive value.
The proportion of DSM-5 and Adult Clinical ADHD Diagnostic Scale (ACDS) cases classified as cases by the screener at the threshold.
The proportion of DSM-5/ACDS noncases classified as noncases by the screener at the threshold.
The probability that a randomly selected DSM-5/ACDS case would have a higher screening scale score than a randomly selected noncase at the threshold, with ties on the screening scale assigned a predicted probability of 0.500.
The proportion of respondents with screening scale scores above the threshold that meet DSM-5/ACDS criteria for the disorder.
Sample of 337 participants; weighted prevalence, 8.2%.
Sample of 300; participants; prevalence, 57.7%.
