This article examines evidence-based assessment practices for attention deficit hyperactivity disorder (ADHD). The nature, symptoms, associated features, and comorbidity of ADHD are briefly described, followed by a selective review of the literature on the reliability and validity of ADHD assessment methods. It is concluded that symptom rating scales based on the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994), empirically and rationally derived ADHD rating scales, structured interviews, global impairment measures, and behavioral observations are evidence-based ADHD assessment methods. The most efficient assessment method is obtaining information through parent and teacher rating scales; both parent and teacher ratings are needed for clinical purposes. Brief, non-DSM based rating scales are highly correlated with DSM scales but are much more efficient and just as effective at diagnosing ADHD. No incremental validity or utility is conferred by structured interviews when parent and teacher ratings are utilized. Observational procedures are empirically valid but not practical for clinical use. However, individualized assessments of specific target behaviors approximate observations and have both validity and treatment utility. Measures of impairment that report functioning in key domains (peer, family, school) as well as globally have more treatment utility than nonspecific global measures of impairment. DSM diagnosis per se has not been demonstrated to have treatment utility, so the diagnostic phase of assessment should be completed with minimal time and expense so that resources can be focused on other aspects of assessment, particularly treatment planning. We argue that the main focus of assessment should be on target behavior selection, contextual factors, functional analyses, treatment planning, and outcome monitoring.

This systematic review examined 140 outcome evaluations of primary prevention strategies for sexual violence perpetration. The review had two goals: 1) to describe and assess the breadth, quality, and evolution of evaluation research in this area; and 2) to summarize the best available research evidence for sexual violence prevention practitioners by categorizing programs with regard to their evidence of effectiveness on sexual violence behavioral outcomes in a rigorous evaluation. The majority of sexual violence prevention strategies in the evaluation literature are brief, psycho-educational programs focused on increasing knowledge or changing attitudes, none of which have shown evidence of effectiveness on sexually violent behavior using a rigorous evaluation design. Based on evaluation studies included in the current review, only three primary prevention strategies have demonstrated significant effects on sexually violent behavior in a rigorous outcome evaluation: Safe Dates (Foshee et al., 2004); Shifting Boundaries (building-level intervention only, Taylor, Stein, Woods, Mumford, & Forum, 2011); and funding associated with the 1994 U.S. Violence Against Women Act (VAWA; Boba & Lilley, 2009). The dearth of effective prevention strategies available to date may reflect a lack of fit between the design of many of the existing programs and the principles of effective prevention identified by Nation et al. (2003).

These findings support the validity of the DSM-IV diagnosis of ADHD in younger children by demonstrating that the symptoms and associated impairment are likely to persist well into elementary school.

The predictive validity of symptom criteria for different subtypes of ADHD among children who were impaired in at least one setting in early childhood was examined. Academic achievement was assessed seven times over 8 years in 125 children who met symptom criteria for ADHD at 4-6 years of age and in 130 demographically-matched non-referred comparison children. When intelligence and other confounds were controlled, children who met modified criteria for the predominantly inattentive subtype of ADHD in wave 1 had lower reading, spelling, and mathematics scores over time than both comparison children and children who met modified criteria for the other subtypes of ADHD. In some analyses, children who met modified criteria for the combined type had somewhat lower mathematics scores than comparison children. The robust academic deficits relative to intelligence in the inattentive group in this age range suggest either that inattention results in academic underachievement or that some children in the inattentive group have learning disabilities that cause secondary symptoms of inattention. Unexpectedly, wave 1 internalizing (anxiety and depression) symptoms independently predicted deficits in academic achievement controlling ADHD, intelligence, and other predictors. KeywordsADHD; Academic achievement; learning disabilities; anxiety; depression; longitudinal outcomes One of the serious difficulties faced by youth who meet criteria for attention-deficit/ hyperactivity disorder (ADHD) is poor academic achievement (DeShazo Barry, Lyman, & Grofer Klinger, 2002;DuPaul, McGoey, Eckert, & Vanbrakle, 2001;Faraone et al., 1993;Frick et al., 1991;Lonigan et al., 1999;McGee, Williams, Share, Anderson, & Silva, 1986;Rapport, Scanlan, & Denney, 1999;Zentall, Smith, Lee, & Wieczorek, 1994). Although academic difficulties are one of the primary justifications for treating ADHD, much remains to be learned about the nature of the academic deficits of children with ADHD. Four issues are particularly important in considering the current data base regarding the academic deficits of children and adolescent with ADHD.Address all correspondence to Greta Massetti, Centers for Disease Control and Prevention, 4770 Buford Highway NE, Atlanta, GA 30341; (770) 488-1349; Fax (770) NIH-PA Author ManuscriptNIH-PA Author Manuscript NIH-PA Author ManuscriptFirst, because children who meet criteria for ADHD have lower intelligence scores than the population mean on average (August & Garfinkel, 1990;Faraone et al., 1993;Frazier, Demaree, & Youngstrom, 2004;Szatmari, Offord, Siegel, Finlayson, & Tuff, 1990), and because intelligence is highly correlated with standardized measures of reading and mathematics (Vanderwood, McGrew, Flanagan, & Keith, 2001), it is necessary to take intelligence into account when studying the academic achievement of children with ADHD. Similarly, because children with ADHD tend to exhibit more symptoms of psychopathology than children without ADHD, and these other forms of psychopathology may be associated with aca...

Objectives: This study examines the tolerability and efficacy of methylphenidate (MPH) and behavior modification therapy (BMOD) in children with attention-deficity/hyperactivity disorder (ADHD) and severe mood dysregulation (SMD). Methods: Children (ages 5-12) from a summer program for ADHD were screened for SMD and additional manic-like symptoms using structured assessments and direct clinical interview with the Young Mania Rating Scale (YMRS). The SMD group was comprised of 33 subjects with SMD and elevated YMRS scores (mean ϭ 23.7). They underwent weekly mood assessments plus the daily ADHD measures that are part of the program. The comparison group (n ϭ 68) was comprised of the rest of the program participants. Using a crossover design, all subjects in both groups were treated with three varying intensities of BMOD (no, low, high) each lasting 3 weeks, with MPH dose (placebo, 0.15 mg/kg t.i.d., 0.3mg/kg t.i.d., and 0.6mg/kg t.i.d.) varying daily within each behavioral treatment. Results: Groups had comparable ADHD symptoms at baseline, with the SMD group manifesting more oppositional defiant disorder/conduct disorder (ODD/CD) symptoms (p Ͻ 0.001). Both groups showed robust improvement in externalizing symptoms (p Ͻ 0.001). There was no evidence of differential treatment efficacy or tolerability. Treatment produced a 34% reduction in YMRS ratings in SMD subjects (p -0.001). However, they still exhibited elevated YMRS ratings, more ODD/CD symptoms (p Ͻ 0.001), and were more likely to remain significantly impaired at home than non-SMD subjects (p Ͻ 0.05). Conclusions: MPH and BMOD are tolerable and effective treatments for children with ADHD and SMD, but additional treatments may be needed to optimize their functioning. 573

Violence among youth is a pervasive public health problem. In order to make progress in reducing the burden of injury and mortality that result from youth violence, it is imperative to identify evidence-based programs and strategies that have a significant impact on violence. There have been many rigorous evaluations of youth violence prevention programs. However, the literature is large, and it is difficult to draw conclusions about what works across evaluations from different disciplines, contexts, and types of programs. The current study reviews the meta-analyses and systematic reviews published prior to 2009 that synthesize evaluations of youth violence prevention programs. This meta-review reports the findings from 37 meta-analyses and 15 systematic reviews; the included reviews were coded on measures of the social ecology, prevention approach, program type, and study design. A majority of the meta-analyses and systematic reviews were found to demonstrate moderate program effects. Meta-analyses yielded marginally smaller effect sizes compared to systematic reviews, and those that included programs targeting family factors showed marginally larger effects than those that did not. In addition, there are a wide range of individual/family, program, and study moderators of program effect sizes. Implications of these findings and suggestions for future research are discussed.

Psychopathy is an early-appearing risk factor for severe and chronic violence. The violence largely attributable to psychopathy constitutes a substantial portion of the societal burden to the public health and criminal justice systems, and thus necessitates significant attention from prevention experts. Yet, despite a vast base of research in psychology and criminology, the public health approach to violence has generally neglected to consider this key variable. Fundamentally, the public health approach to violence prevention is focused on achieving change at the population level to provide the most benefit to the maximum number of people. Increasing attention to the individual-level factor of psychopathy in public health could improve our ability to reduce violence at the community and societal levels. We conclude that the research literature on psychopathy points to a pressing need for a broad-based public health approach with a focus on primary prevention. Further, we consider how measuring psychopathy in public health research may benefit violence prevention, and ultimately society, in general.

The Division of Violence Prevention within CDC's National Center for Injury Prevention and Control recently undertook a systematic review of primary prevention strategies for sexual violence (SV) perpetration. This review identified the lack of community-level strategies to prevent SV as a critical gap in the literature. Community-level strategies function by modifying the characteristics of settings (e.g., schools, workplaces, neighborhoods) that increase the risk for violence victimization and perpetration. Identification of evidence-based strategies at the community level would allow implementation of ecologic approaches to SV prevention with a greater potential for reducing the prevalence of SV perpetration. The field will face several challenges in identifying and evaluating the effectiveness of promising community-level strategies to prevent SV. These challenges include limited knowledge of community-level and societal-level risk factors for SV, a lack of theoretical or empirical guidance in the SV literature for identification of promising community-level approaches, and challenges in evaluating SV outcomes at the community level. Recognition of these challenges should guide future research and foster dialogue within the SV prevention field. The development and evaluation of community-level approaches to SV prevention represent a vital and logical next step toward the implementation of effective, multilevel prevention efforts and a population-level reduction in the prevalence of SV.
