Correction to Barkley et al. (2011).

Reports an error in "Correspondence and disparity in the self- and other ratings of current and childhood ADHD symptoms and impairment in adults with ADHD" by Russell A. Barkley, Laura E. Knouse and Kevin R. Murphy (Psychological Assessment, , , np). There was an omission in the author note. The author note should have included a disclosure as follows, “Russell A. Barkley receives royalties for books, videos, and rating scales from Guilford Publications, and is the author of Barkley Adult ADHD Rating Scale-IV (BAARS-IV), Barkley Deficits in Executive Functioning Scale (BDEFS), and Barkley Functional Impairment Scale (BFIS), all published by Guilford Press.” (The following abstract of the original article appeared in record 2011-04636-001.) Experts recommend that clinicians evaluating adults for attention-deficit/hyperactivity disorder (ADHD) obtain information from others who know the patient well. The authors examined correspondence between the self- and other-ratings of ADHD symptoms and impairment using 3 groups of adults recruited on the basis of their severity of ADHD: ADHD diagnosis (n = 146), clinical controls self-referring for ADHD but not diagnosed (n = 97), and community controls (n = 109). The influences of diagnostic group, informant relationship, sex of participant, IQ, and comorbid anxiety and depression on self-informant disparities were also examined. Results indicated moderate to high agreement (.59–.80) between self and others on current functioning and slightly lower levels (.53–.75) between self- and parent ratings of childhood functioning. Examination of difference scores between self- and other ratings revealed small mean disparities (?0.1 to +5.0 points) but substantial variation (SDs = –2.4 to 8.9 points) for both current and childhood ratings. Clinic referrals not diagnosed with ADHD, particularly women, had higher disparities than was evident in the ADHD and community groups. Age, IQ, and education were not associated with disparities in most ratings. Higher anxiety, in contrast, was associated with greater disparities on all current and childhood measures of both ADHD and impairment. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
