OBJECTIVE: To develop an adult self-report instrument for provisional diagnosis of four common mental disorders in primary care patients. METHODS: Primary care patients were evaluated during routine clinic visits with a self-report screening tool comprised of 85 DSM-IV symptom-based candidate questions. Patients with a physician-assessed provisional diagnosis for generalized anxiety disorder (GAD), major depressive episode (MDE), past/present mania, and adult attention-deficit/hyperactivity disorder (ADHD), or none of these, completed additional self-report clinical questionnaires, and then were interviewed on the telephone by a trained rater for a SCID/ACDS diagnosis. Responses to the symptom-based candidate questions were used to calculate sensitivity and specificity for a SCID/ACDS diagnosis (GAD, N = 24; MDE, N = 89; Mania, N = 24; ADHD, N = 65) and to select the optimal four questions for each diagnosis to be included in the instrument. RESULTS: Analyses resulted in a 17-item instrument for provisional differential diagnosis of GAD, MDE, past/present mania, and ADHD. Comparison of limited symptom-based versus full DSM-IV criteria-based diagnosis showed minimal differences for relative diagnostic accuracy. Sensitivities and specificities, respectively, were 83% and 75% for GAD, 80% and 80% for MDE, 83% and 82% for mania, and 82%and 73% for ADHD. CONCLUSIONS: Based on this preliminary work, the Provisional Diagnostic Instrument-4 is a brief, easily scored, self-report instrument that may assist primary care physicians to identify potential cases of GAD, MDE, past/present mania, and ADHD

OBJECTIVE: High smoking rates in adults with attention-deficit/hyperactivity disorder (ADHD) and nicotine's amelioration of ADHD suggest that effective ADHD treatment might facilitate abstinence in smokers with ADHD. The present study evaluated if using osmotic-release oral system methylphenidate (OROS-MPH) to treat ADHD enhances response to smoking cessation treatment in smokers with ADHD. METHOD: A randomized, double-blind, placebo-controlled, 11-week trial with a 1-month follow-up was conducted at 6 clinical sites between December 2005 and January 2008. Adults (aged 18-55 years) meeting DSM-IV criteria for ADHD and interested in quitting smoking were randomly assigned to OROS-MPH titrated to 72 mg/d (n = 127) or placebo (n = 128). All participants received brief weekly individual smoking cessation counseling for 11 weeks and 21 mg/d nicotine patches starting on the smoking quit day (day 27) through study week 11. Outcome measures included prolonged smoking abstinence and DSM-IV ADHD Rating Scale (ADHD-RS) score. RESULTS: Of 255 randomly assigned participants, 204 (80%) completed the trial. Prolonged abstinence rates, 43.3% and 42.2%, for the OROS-MPH and placebo groups, respectively, did not differ significantly (OR = 1.1; 95% CI, 0.63-1.79; P = .81). Relative to placebo, OROS-MPH evidenced a greater reduction in DSM-IV ADHD-RS score (P < .0001) and in cigarettes per day during the post-quit phase (P = .016). Relative to placebo, OROS-MPH increased blood pressure and heart rate to a statistically, but not clinically, significant degree (P < .05); medication discontinuation did not differ significantly between treatments. CONCLUSIONS: Treatment for ADHD did not improve smoking cessation success; OROS-MPH, relative to placebo, effectively treated ADHD and was safe and generally well tolerated in this healthy sample of adult ADHD smokers.

CONTEXT: Controversy exists about the appropriate criteria for a diagnosis of adult attention-deficit/hyperactivity disorder (ADHD). OBJECTIVE: To examine the structure and symptoms most predictive of DSM-IV adult ADHD. DESIGN: The data are from clinical interviews in enriched subsamples of the National Comorbidity Survey Replication (n = 131) and a survey of a large managed health care plan (n = 214). The physician-administered Adult ADHD Clinical Diagnostic Scale (ACDS) was used to assess childhood ADHD and expanded symptoms of current adult ADHD. Analyses examined the stability of symptoms from childhood to adulthood, the structure of adult ADHD, and the adult symptoms most predictive of current clinical diagnoses. SETTING: The ACDS was administered telephonically by clinical research interviewers with extensive experience in the diagnosis and treatment of adult ADHD. PARTICIPANTS: An enriched sample of community respondents. MAIN OUTCOME MEASURE: Diagnoses of DSM-IV /ACDS adult ADHD. RESULTS: Almost half of the respondents (45.7%) who had childhood ADHD continued to meet the full DSM-IV criteria for current adult ADHD, with 94.9% of these patients having current attention-deficit disorder and 34.6% having current hyperactivity disorder. Adult persistence was much greater for inattention than for hyperactivity/impulsivity. Additional respondents met the full criteria for current adult ADHD despite not having met the full childhood criteria. A 3-factor structure of adult symptoms included executive functioning (EF), inattention/hyperactivity, and impulsivity. Stepwise logistic regression found EF problems to be the most consistent and discriminating predictors of adult DSM-IV /ACDS ADHD. CONCLUSIONS: These findings document the greater persistence of inattentive than of hyperactive/impulsive childhood symptoms of ADHD in adulthood but also show that inattention is not specific to ADHD because it is strongly associated with other adult mental disorders. In comparison, EF problems are more specific and consistently important predictors of DSM-IV adult ADHD despite not being in the DSM-IV, suggesting that the number of EF symptoms should be increased in the DSM-V/ICD-11

Deficits in executive function have been consistently demonstrated in adults with ADHD. Rating scales that measure executive deficits in relation to daily life are useful in assessing ADHD symptoms and in measuring responses to treatment, while neuropsychological testing can measure deficits in executive function that can cause additional impairment in adults with ADHD. Treatments, including psychosocial interventions and stimulant and nonstimulant medications, can be helpful in addressing these executive deficits and the symptoms of adult ADHD

OBJECTIVE: Validation of the Adult ADHD Investigator Symptom Rating Scale (AISRS) that measures aspects of ADHD in adults. METHOD: Psychometric properties of the AISRS total and AISRS subscales are analyzed and compared to the Conners' Adult Attention-Deficit/Hyperactivity Disorder Rating Scale-Investigator Rated: Screening Version (CAARS-Inv:SV) and the Clinical Global Impression-ADHD-Severity Scale using data from a placebo-controlled 6-month clinical trial of once-daily atomoxetine. RESULTS: The AISRS has high internal consistency, good convergent, and discriminant validities; modest divergent validity; and small ceiling and floor effects (<or=1%). It correlates highly with the CAARS-Inv:SV. Factor analysis confirms 2 AISRS subscales, hyperactivity-impulsive scale and inattention. The AISRS total and AISRS subscales perform stably. All scales demonstrate responsiveness to change with medication. CONCLUSION: The AISRS and its subscales are robust, valid efficacy measures of ADHD symptoms in adult patients. Its anchored items and semistructured interview are advancements over existing scales

Treatment-resistant depression may be related to polymorphisms in the promoter region of the serotonin transporter gene (5-HTTLPR) or dysregulation of noradrenergic systems. To examine 5-HTTLPR genotypes and responses to treatment, adult patients (N=261) with current major depression and a symptom severity rating > or =8 on the 17-item Hamilton Depression Rating Scale (HAMD(17)) were treated for 8 weeks with open-label sertraline (100-200 mg/d). Patients remaining symptomatic (total score >4, or >1 on any item of the HAMD(17) Maier-Philipp subscale) were randomly assigned to double-blind therapy with sertraline plus either atomoxetine (40-120 mg/d) or placebo for 8 additional weeks. 5-HTTLPR genotype did not predict responses to sertraline monotherapy or discontinuation rates. Among the 138 patients remaining symptomatic after sertraline monotherapy (L/L = 21%, S/L = 50%, S/S = 29%), significantly more S/S-genotype patients achieved remission under combined sertraline/atomoxetine treatment relative to the other genotypes (S/S = 81.8%; non-S/S = 32.7%), but not under sertraline/placebo treatment (S/S = 35.7%; non-S/S = 37.7%). Minor genotypic differences were noted in adverse event profiles. In patients with poor responses to sertraline monotherapy for depression, addition of atomoxetine may improve responses to treatment of depression in S/S-genotyped patients. Although this study is speculative, it represents a pharmacologically and genotypically well-defined patient population

Objective: Atomoxetine is a nonstimulant medication for treating child, adolescent, and adult ADHD. This meta-analysis compared the effects in younger and older adults. Method: A post hoc analysis was conducted using data from two double-blind, placebo-controlled clinical trials. Data from patients aged 18-25 years were compared with data from patients older than 25 years. Results: In younger adults (mean age = 21.7), atomoxetine produces greater improvement than placebo on the Conners' Adult ADHD Rating Scale's total ADHD symptom score (p = .041, effect size = .797) and the clinical global impressions severity (p = .006, effect size = 1.121). In older adults (mean age = 43.4 years), atomoxetine also produces significant benefit on the CAARS-Inv:SV (p < .001, effect size = .326) and CGI-ADHD-S (p < .001, effect size = .346). The study findings reveal response rates to be 56.4% and 47.8% for the younger and older adults, respectively (p = .188). Tolerability is similar although older adults reported more sexual side effects. Conclusion: Younger and older adults show similar improvements at endpoint. The effect size is higher in younger adults, but this is due primarily to greater variability of response in older patients

[Correction Notice: An erratum for this article was reported in Vol 17(5) of Primary Psychiatry (see record 2010-13373-007). There was a typographical error on page 47 of the original article. The sentence read: 'Based on the link function from the adult study, baseline ADHD-RS-IV scores ranging from 13.5-7.4 are expected to correspond to CGI-S levels of mildly to moderately ill.' The correct range should be '13.5-37.4' as noted correctly in Table 2 on page 48.] Objective: To provide additional understanding of the clinical significance of Attention-Deficit/Hyperactivity Disorder Rating Scale, Version IV (ADHD-RS-IV) total and change scores in relation to Clinical Global Impressions-Severity or -Improvement (CGI-S/-I) levels. Methods: Using two similarly designed pivotal trials of lisdexamfetamine dimesylate (Vyvanse, Shire US Inc), equipercentile linking was used to identify scores on the ADHD-RS-IV and CGI that have the same percentile rank. Results: As assessed by CGI-S levels, moderately, markedly, severely, and extremely ill adults had mean (SD) baseline ADHD-RS-IV scores of 36.2 (4.9), 42.1 (6.1), 45.4 (5.1), and 53.0, respectively. A similar relationship was observed in children. At endpoint, children categorized as minimally, much, or very much improved by CGI-I demonstrated mean (SD) ADHD-RS-IV changes from baseline of -9.9 (6.8), -25.5 (7.2), and -33.2 (9.3), respectively. Adults demonstrated a similar relationship between ADHD-RS-IV change scores and CGI-I ratings. Based on equipercentile link function, a change from baseline in ADHD-RS-IV total score of ~10-15 points or 25% to 30% corresponded to a change of 1 level in CGI-I score. Conclusion: This analysis makes possible the establishment of a clinical impression of severity of illness from total ADHD-RS-IV scores and may facilitate the clinical interpretation of improvement of ADHD-RS-IV change scores.

OBJECTIVE: The purpose of this 10-week, open-label trial was to evaluate the potential utility of atomoxetine for improving attention-deficit hyperactivity disorder (ADHD) and substance craving in abstinent adults with ADHD who were being treated at a residential treatment facility. METHODS: Eighteen adults were treated with atomoxetine (25-120 mg/day) for up to 10 weeks. Researchers assessed ADHD symptoms with the Adult ADHD Investigator Symptom Rating Scale (AISRS) and substance cravings with the Brief Substance Craving Scale (BSCS). Paired t-tests were used to assess changes in symptoms and craving. RESULTS: Among the 12 participants who completed at least 2 weeks of treatment, mean total AISRS scores improved (43.2 SD 7.4 to 25.8 SD 14.4, t = 5.0, p.001). Participants also reported improvement in some measures of cravings. CONCLUSIONS: These data provide preliminarily support for the utility of atomoxetine in abstinent adults with co-occurring ADHD and substance use disorder.
