BACKGROUND: An 8-week placebo-controlled study, the Research Units on Pediatric Psychopharmacology Anxiety Study, documented beneficial effects of fluvoxamine in the treatment of pediatric social anxiety, separation anxiety, or generalized anxiety disorders. Following completion of this study, participants were invited to enter a 6-month open-label treatment phase designed to examine three issues: (a) long-term maintenance of response in fluvoxamine responders, (b) acute response to fluoxetine in fluvoxamine nonresponders, and (c) acute response to fluvoxamine in placebo nonresponders. METHODS: Participants aged 6-17 years meeting criteria for social anxiety, separation anxiety, or generalized anxiety disorders previously treated in an 8-week placebo-controlled trial (n = 128) were offered open treatment. Changes in symptoms of anxiety during open treatment were assessed in three groups: (a) fluvoxamine responders maintained on fluvoxamine, (b) fluvoxamine nonresponders changed to fluoxetine, and (c) placebo nonresponders changed to fluvoxamine. Response was defined based on Clinical Global Impression criteria. RESULTS: During 6 months of continued open treatment, anxiety symptoms remained low in 33 of 35 (94%) subjects who initially responded to fluvoxamine. Among 14 fluvoxamine nonresponders switched to fluoxetine, anxiety symptoms appeared significantly improved in 10 (71%) subjects. Finally, among 48 placebo nonresponders, 27 (56%) showed clinically significant improvement in anxiety on fluvoxamine. CONCLUSION: The current findings concerning extended treatment of pediatric anxiety disorders are only preliminary, because treatment was uncontrolled. Results suggest that an initial fluvoxamine response is likely to be retained with continued treatment, that some fluvoxamine nonresponders may respond to fluoxetine, and that some placebo nonresponders may respond to fluvoxamine

Examined hypothesized gender and comorbidity differences in the observed classroom behavior of children with attention deficit hyperactivity disorder (ADHD). The behavior of 403 boys and 99 girls with ADHD, ages 7-10, was compared (a) to observed, sex-specific classroom behavior norms, (b) by sex, and (c) by comorbid subgroups. Boys and girls with ADHD deviated significantly from classroom norms on 15/16 and 13/16 categories, respectively. Compared to comparison girls, girls with ADHD had relatively high rates of verbal aggression to children. Boys with ADHD engaged in more rule-breaking and externalizing behaviors than did girls with ADHD, but the sexes did not differ on more 'neutral,' unobtrusive behaviors. The sex differences are consistent with notions of why girls with ADHD are identified and referred later than boys. Contrary to hypothesis, the presence of comorbid anxiety disorder (ANX) was not associated with behavioral suppression; yet, as hypothesized, children with a comorbid disruptive behavior disorder (DBD) had higher rates of rule-breaking, and impulsive and aggressive behavior, than did children with ADHD alone and those with ADHD+ANX. Elevated rates of ADHD behaviors were also observed in children with comorbid DBD, indicating that these behaviors are truly present and suggesting that reports of higher ADHD ratings in this subgroup are not simply a consequence of negative halo effects and rater biases

In the December 2000 issue of the Journal of Abnormal Child Psychology, we published a set of papers presenting secondary analyses of the Multimodal Treatment Study of ADHD (MTA), and R. A. Barkley (2000) provided a commentary. A critique of the design of the study (MTA Cooperative Group, 1999) was presented based on a theoretical perspective of a 'behavioral inhibition' deficit that has been hypothesized as the core deficit of ADHD (R. A. Barkley, 1997). The commentary questioned the design and analysis of the MTA in terms of (1) the empirical criteria for selection of components of behavioral (Beh) intervention, (2) the effectiveness of the Beh intervention, (3) the methods for analyses at the group and individual level, (4) implications of the MTA findings for clinical practice, (5) the role of genetics in response to treatment, and (6) the lack of a nontreatment control group. In this response, we relate the content of the papers to the commentary, (1) by reviewing the selection criteria for the Beh treatment, as outlined by K. C. Wells, W. E. Pelham, et al. (2000), (2) by addressing the myth that the MTA Beh treatment was ineffective (Pelham, 1999), (3) by describing the use of analyses at the level of the individual participant, as presented by J. S. March et al. (2000) and W. E. Pelham et al. (2000) as well as elsewhere by J. M. Swanson et al. (2001) and C. K. Conners et al. (2001), (4) by relating some of the suggestions from the secondary analyses about clinically relevant factors such as comorbidity (as presented by J. S. March et al., 2000) and family and parental characteristics (as presented by B. Hoza et al., 2000, S. P. Hinshaw et al., 2000, and K. C. Wells, J. N. Epstein, et al., 2000), (5) by discussing the statistical concept of heritability and the lack of a significant difference in the presence of ADHD symptoms in parents of the MTA families compared to parents in the classmate-control families (as presented by J. N. Epstein, et al., 2000), and (6) by acknowledging that an ethically necessary weakness of the MTA design is that it did not include a no-treatment control group. We discuss the use of secondary analyses to suggest how, when, and for what subgroups effectiveness of the Beh treatment may have been manifested. Finally, we invite others to use the large and rich data set that will soon be available in the public domain, to perform secondary analyses to mine the meaning of the MTA and to evaluate theories of ADHD and response to treatments

Treatment studies in child and adolescent psychiatry are increasingly characterized by long-term, multisite, randomized clinical trials (RCTs). During the course of these RCTs it is common for clinical exigencies to emerge that require rapid, direct intervention. The challenge is to provide clinically appropriate responses that do not contaminate the delivery, distinctness, and interpretation of the treatments under investigation. In multisite studies, the problem is compounded by the need to minimize cross-site differences in the delivery of adjunct treatments. Such minimization requires fully operationalized and manual-based procedures for clinically mandated intervention. The NIMH Collaborative Multisite Multimodal Treatment Study of Children With Attention-Deficit/Hyperactivity Disorder (ADHD)--'the MTA'--is a long-term multisite collaborative study in which children with ADHD were randomly assigned to either medication management, behavioral treatment, the combination, or community-comparison assessment and referral. In designing its study, the MTA developed a manual-based set of procedures (the MTA Adjunct Services and Attrition Prevention [ASAP] Manual) for situations not covered by the protocol treatments. The majority of cases requiring adjunct services fell into two major categories: (1) crisis/emergent situations and (2) imminent risk of attrition. This report describes the ASAP guidelines for dealing with cases that required adjunct services that the MTA Steering Committee adopted before initiating the trial. Although the manual-based guidelines are especially applicable to multisite RCTs, many of the procedures in the ASAP Manual can apply to any treatment study in children

This study evaluated children's symptoms 3 and 9 months after the 1993 bombing of the World Trade Center, and the relationship between parent and child reactions when only the children had been in the building. Nine children who had been trapped in an elevator, 13 who had been on the observation deck, and 27 controls completed the Posttraumatic Stress Reaction Index and a Fear Inventory. Parents completed these measures about the children and comparable measures about themselves. Exposed children reported posttraumatic stress disorder (PTSD) symptoms and disaster-related fears; their parents reported experiencing PTSD symptoms. Only parents rated children's symptoms as decreasing significantly over time. Association between child symptoms and parent symptoms increased over time. Children's initial distress predicted parents' distress 9 months postdisaster

OBJECTIVE: To explore whether socioeconomic status (SES) variables moderate treatment response of attention-deficit/hyperactivity disorder (ADHD) to medication management (MedMgt), behavioral treatment (Beh), combined intervention (Comb), and routine community care (CC). METHOD: The MTA Cooperative Group's intent-to-treat (ITT) analyses were repeated, covarying for composite Hollingshead SES, education, occupation, income, and marital status. RESULTS: Individual SES variables were more informative than the composite Hollingshead Index. Treatment response of children from less educated households paralleled ITT outcomes: no significant difference was found between Comb and MedMgt (both better than Beh and CC) for core ADHD symptoms. However, children from more educated families showed superior reduction of ADHD symptoms with Comb. For oppositional-aggressive symptoms, children from blue-collar, lower SES households benefited most from Comb, whereas those from white-collar, higher SES homes generally showed no differential treatment response. Household income and marital status failed to influence outcomes. Controlling for treatment attendance attenuated the moderating effects of the SES variables only for MedMgt. CONCLUSIONS: Investigators are encouraged to use independent SES variables for maximal explanation of SES effects. Clinicians should prioritize target symptoms and consider the mediating role of treatment adherence when determining an ADHD patient's optimal intervention plan

Presents a consensus statement on attention deficit hyperactivity disorder (ADHD) as a reference on the status of scientific findings concerning this disorder, its validity, and its adverse impact on the lives of those diagnosed with the disorder. It is emphasized that, as a matter of science, the notion that ADHD does not exist is simply wrong. The international scientists authoring this consensus recognize the mounting evidence of neurological and genetic contributions to ADHD. This evidence, couples with countless studies on the harm posed by ADHD and studies on the effectiveness of medication, highlight the need in many cases for management of the disorder with multiple therapies. Despite the serious consequences of ADHD, studies indicate that less than half of those with the disorder are receiving treatment. The media can help by depicting ADHD as realistically and accurately as it is depicted in science--as a valid disorder having varied and substantial adverse impact on those who suffer from it.

Drugs that selectively inhibit serotonin reuptake are effective treatments for adults with mood and anxiety disorders, but limited data are available on the safety and efficacy of serotonin-reuptake inhibitors in children with anxiety disorders. 128 children (aged 6-17 yrs) who met the criteria for social phobia, separation anxiety disorder, or generalized anxiety disorder, and who had received psychological treatment for 3 wks without improvement were studied. The children were randomly assigned to receive fluvoxamine or placebo for 8 wks and were evaluated with rating scales designed to assess the degree of anxiety and impairment. Children in the fluvoxamine group had a mean decrease of 9.7 points in symptoms of anxiety on the Pediatric Anxiety Rating Scale, as compared with a decrease of 3.1 points among children in the placebo group. On the Clinical Global Impressions-Improvement scale, 48 of 63 children in the fluvoxamine group had a response to the treatment, as compared with 19 of 65 children in the placebo group. It is concluded that fluvoxamine is an effective treatment for children and adolescents with social phobia, separation anxiety disorder, or generalized anxiety disorder.
