P. Roybyrne et al., ADULT ATTENTION-DEFICIT HYPERACTIVITY DISORDER - ASSESSMENT GUIDELINES BASED ON CLINICAL PRESENTATION TO A SPECIALTY CLINIC, Comprehensive psychiatry, 38(3), 1997, pp. 133-140
Of 143 adults presenting for attention-deficit hyperactivity disorder
(ADHD) evaluation, 46 (32%) clearly met diagnostic criteria, 46 (32%)
clearly did not meet diagnostic criteria, and another 51 (36%) with cu
rrent ADHD-like features did not meet criteria due to either a lack of
childhood history and/or complicating severe psychiatric or substance
abuse comorbidity. The three groups were similar in demographics, psy
chiatric diagnosis, psychiatric symptom severity, and functional impai
rment. Compared with the group not meeting ADHD criteria, patients wit
h ADHD had more frequent histories of learning disability in childhood
, poorer reading scores on the Wide-Range Achievement Test (WRAT), poo
rer scores on the Continuous Performance Test (CPT), and higher scores
on the Wender-Utah Rating Scale (WURS) for ADHD. Patients in the ambi
guous ADHD category had higher rates of current substance abuse than t
he other two groups. While this group resembled the non-ADHD group in
having a low incidence of learning disability and normal reading score
s, their poor performance on the CPT and high scores on the WURS more
closely resembled those of ADHD patients. These findings suggest that
there are a few rating scales, testing instruments, and lifetime histo
ry characteristics that help to clarify the difficult diagnostic disti
nction between adult patients who do and do not have ADHD. Copyright (
