Abstract
This study examined the predictive relations from symptoms of Attention-deficit/hyperactivity disorder (ADHD) and executive functioning (EF) to social and school functioning in 112 (62 girls) school children. High levels of teacher and parent ratings of ADHD symptoms at the ages of 8-8 1/2 years, and poor EF measured at the age of 8 1/2, were associated with poor social functioning measured by peer nominations and poor teacher ratings of school functioning at the age of 9 1/2. ADHD symptoms independently predicted social and school functioning, whereas EF independently predicted only school functioning. Interaction effects between ADHD and EF and between EF and gender were found: At high levels of symptoms of inattention, the poorer the EF, the greater the need for special education. At high levels of symptoms of hyperactivity/impulsivity, the poorer the EF, the higher the levels of physical aggression. Girls with poor EF were less accepted by peers than equivalent boys.

Abstract
We assessed the predictive validity of attention-deficit/hyperactivity disorder (ADHD) in 20 girls and 98 boys who met the Diagnostic and Statistical Manual for Mental Disorders (4th ed., American Psychiatric Association, 1994) criteria for ADHD at 4 to 6 years of age compared to 24 female and 102 male comparison children. Over the next 8 years, both girls and boys who met criteria for ADHD in Year 1 exhibited more ADHD symptoms and impairment than same-sex comparison children. Effect sizes were consistently large, indicating that the diagnosis of ADHD at 4 to 6 years of age has predictive validity for both sexes. Both girls and boys with ADHD in Year 1 also exhibited higher levels of symptoms of conduct disorder, major depression, and anxiety disorders in early adolescence than same-sex comparison children, controlling levels of the same symptoms in Year 1. This indicates both substantial homotypic and heterotypic continuity for ADHD in both sexes, but significant interactions with time indicated that childhood ADHD predicts more steeply rising symptoms of anxiety and depression during early adolescence in girls than in boys.

Abstract
Neuropsychological methods and techniques have much to offer in the evaluation of the individual suspected as having Attention-Deficit/Hyperactivity Disorder (ADHD). After a review of the historical evolution of the ADHD concept, incidence and prevalence, and DSM-IV criteria for diagnosis, especially as regards omission related to gender differences, and other associated cultural, familial, socioenvironmental, and subject influences, this paper describes a number of dilemmas and obstacles encountered in clinical practice. Included are the confounds associated with the wide range of possible comorbidities, the insufficiency of current DSM-IV criteria, the emergence of subtype differentiation and its impact on diagnosis and treatment. The complex relationship between neuropsychological constructs and ADHD, and obstacles to valid assessment are also addressed. The complexities associated with a thorough ADHD evaluation are viewed within an impressive and expansive existing scientific framework and recommendations are made for future directions.

Abstract
This article explores the impact of diagnostic/psychiatric labelling on the attitudes and behavioural intentions of school-aged children towards a hypothetical peer presented with symptoms of attention deficit hyperactivity disorder (ADHD). A sample of 120 children aged 11-12 years read one of three vignettes describing the behaviour of a gender-neutral, same-age peer presenting with symptoms of ADHD. The participants completed self-report measures of attitudes and behavioural intentions after reading the respective vignettes. The majority of participants perceived the vignette character as being male and the attitude held towards him was predominately negative. Significant positive relationships were found between attitudes and children's willingness to engage in social, academic and physical activities. Diagnostic/psychiatric labelling had no additional influence upon attitudes or behavioural intentions. Children's negative attitude towards peers with symptoms of ADHD, given its association with friendship choice, is an important target for change in reducing stigma.

Abstract
Diagnosing attention deficit hyperactivity disorder (ADHD) in adults requires retrospective assessment of ADHD symptoms in childhood. The Wender Utah Rating Scale (WURS) and its German validated version (WURS-k) may offer a helpful tool to acertain relevant childhood problems associated with ADHD. Up to now validating data of the WURS-k were limited to male population. In a population of 69 female adult ADHD patients and 97 controls, ROC analysis indicated a sensitivity of 93% and specificity of 92% at a cut-off of 30 points in the WURS-k. This cut-off value is equivalent to those of males. Symptom report varies significantly by gender and females describe more internalizing problems while males report more externalizing behaviour. Regarding different subtypes according to DSM-IV males and females did not differ in the items of the WURS-k.

Abstract
This study explores the social impact of ADHD, with and without opposition-defiant behaviour (ADHD+ODD (n= 22) and ADHD-only (n= 18)), in 9- to 12- year old girls compared to girls without ADHD (n= 40). Girls played a computer game involving simulated players, and mothers and teachers completed rating scales. In general, mothers and teachers saw girls with ADHD+ODD as more overtly and relationally aggressive and less prosocial than girls with ADHD-only, who were seen as more overtly and relationally aggressive and less prosocial than control girls. On the computer game, girls with ADHD+ODD were more overtly aggressive, more directly relationally aggressive, and showed less skilled behaviour than the other groups. Girls with ADHD-only showed less covert, indirect relational aggression and more socially awkward interactions than girls in the control group on the computer game. In all, the results indicate that girls with ADHD, with and without ODD behaviour, engage in socially detrimental behaviours.

Abstract
This study examined 3-year-old children who were classified as hyperactive (HYP), oppositional-defiant (OD), hyperactive and oppositional defiant (HYP/OD), and non-problem based on mothers' reports of behavior. Using fathers,' teachers,' and observers' ratings of children's behavior, concurrent validity was excellent for the HYP/OD group, moderate for the HYP group, and poor for the OD group. As predicted, both the HYP/OD and HYP groups reported more prenatal/perinatal birth complications and a greater family history of hyperactivity than did non-problem children. Furthermore, the HYP/OD group showed a greater family history of conduct disorder and oppositional defiant disorder (ODD) symptoms than did non-problem children; however, the HYP group also showed a greater family history of ODD than did non-problem children. Results suggest that as early as age 3, these behavior subtypes appear to be linked to biologically-based risk-factors in ways that are consistent with theories of the development of ADHD.

Abstract
The aim of the present study is to verify if gender modifies the clinical, adaptative and psychological outcomes of adult attention-deficit/hyperactivity disorder (ADHD) subtypes. We evaluated 219 clinically referred adult patients. The interviews followed the DSM-IV criteria,using the K-SADS-E for ADHD and oppositional defiant disorder and SCID-IV for comorbidities. Regression models were used to analyze gender and subtype main effects and interactions in psychiatric outcomes. In the initial sample, 117 patients (53.5%) were of the combined subtype, 88 (40%) were inattentives and 14 (6.5%) hyperactives. There were no significant interactions between gender and subtype in any variable assessed. Men and women did not differ in the relative frequency of each subtype. Patients of the combined subtype in both genders presented a higher severity and increased rates of conduct and ODD disorders than inattentives. The main effects of gender and subtype in this sample are similar to those previously reported in other countries, suggesting the cross-cultural equivalence of the phenotype. The absence of significant interactions between gender and subtype suggests that, at least in clinical-based samples, DSM-IV adult ADHD subtypes present cross-gender validity.

Abstract
BACKGROUND Observation studies of students with attention-deficit hyperactivity disorder (ADHD) problems in natural classroom situations are costly and relatively rare. AIMS The study enquired how teacher ratings are anchored in actual student classroom behaviours, and how the behaviour of children with ADHD problems differs from their classmates. The authors attempted to broaden the usual focus on disruptive and inattentive behaviours to elucidate the role of various on-task behaviours, as well as considering differences between classroom contexts. SAMPLE DSM-III-R criteria were used in conjunction with a teacher rating scale to select a sample of 55 students with ADHD problems, and 55 matched controls from a population of 569 primary school students. METHOD Students were observed in their natural classrooms using the Munich Observation of Attention Inventory (MAI; Helmke, 1988). Correlations between teacher reports and observation codes were computed, and systematic differences between students with ADHD problems and controls in different classroom contexts were examined using a generalized linear mixed model (GLMM). RESULTS Global teacher reports showed moderate to strong correlations with observed student behaviours. Expected on-task behaviour demonstrated the strongest relationship (r>-.70) with teacher reports. As hypothesized, the children with ADHD were more disruptive and inattentive than their matched peers. They were also less often inconspicuous on-task as expected by their teachers. However, their behaviour was assigned to two other on-task categories more often than their peers, and this raised their total on-task behaviour to over 66%. Situational differences were found for all codes as well, which mostly affected all students in a similar way, not just students with ADHD. CONCLUSIONS ADHD related behaviours are pervasive across the classroom situations coded. Teachers appear to distinguish between desirable and undesirable on-task behaviours. Nevertheless, assisting students with ADHD problems requires shaping both. Future studies need to include more differentiated codes for various types of on-task behaviours and also need to code the lesson context concurrently.

Abstract
The authors investigated whether sex-specific norms should be used to assess symptoms of attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) in girls. It was hypothesized that (a) there would be a group of girls who exhibit ADHD or ODD symptoms using sex-specific norms but not using Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) criteria; (b) these girls would be significantly impaired relative to typically developing girls. These hypotheses were examined using behavior ratings completed by mothers and teachers of 1,491 elementary school students. Results showed that there was a small group of girls who did not meet DSM-IV criteria for ADHD or ODD but who had elevated ADHD and ODD scores when sex-specific norms were used. The same was not true for boys. The girls identified with sex-specific norms were more impaired than other girls. These results suggest that there may be a small number of girls who have behaviors and impairment that are consistent with ADHD and ODD, but they are not currently being identified by DSM-IV criteria.

Abstract
OBJECTIVE First, to investigate whether non-Western children in the Netherlands are less likely to be treated for behavioral problems than Western children; second, to examine whether discrepancies in treatment status are related to differences in level of problem behavior and impairment. METHOD The study included 2,185 children of the four largest ethnic groups in the Netherlands, namely, 684 Dutch, 702 Moroccan, 434 Turkish, and 365 Surinamese children from grades three to five of elementary school. Teachers completed the Strengths and Difficulties Questionnaire and five DSM-IV items on externalizing problems. In addition, they provided information on the treatment status of the child. RESULTS Moroccan boys displayed more problem behavior, Turkish boys less problem behavior, and Surinamese boys similar rates of problem behavior compared with Dutch boys. No difference in problem behavior was found between Western and non-Western girls. Adjusted for age, level of problem behavior, and impairment, Moroccan and Turkish children and Surinamese girls were less likely to receive treatment for problem behavior. CONCLUSIONS The higher treatment thresholds of non-Western children compared with Western children in the Netherlands could not be explained by differences in level of problem behavior or impairment. Detection of behavioral problems in non-Western children should receive more attention.

Abstract
BACKGROUND Because the scientific literature on the pharmacotherapy of attention-deficit/hyperactivity disorder (ADHD) is almost entirely based on the results of studies in samples consisting primarily of boys, much is unknown about the treatment response in girls. OBJECTIVE This post hoc analysis compared the efficacy, tolerability, and time course of the effect of mixed amphetamine salts extended release (MAS XR) and atomoxetine in school-age girls with ADHD. METHODS This was an intent-to-treat subanalysis of the data from girls enrolled in a multicenter, 18-day, randomized, double-blind, parallel-group, forced dose-titration, laboratory school study enrolling boys and girls aged 6 to 12 years with ADHD. The study compared the efficacy, tolerability, and time course of the effect of increasing doses of MAS XR (10, 20, and 30 mg/d) and atomoxetine (0.5 and 1.2 mg/kg per day). The laboratory school sessions were organized in cycles to include 12 hours of observation. Efficacy measures included the SKAMP (Swanson, Kotkin, Agler, M-Flynn, and Pelham) deportment rating subscale, the SKAMP attention rating subscale, and academic testing (number of math problems attempted and answered correctly). Adverse events were assessed throughout the study period. Tolerability and efficacy measures were assessed during laboratory school visits on days 7, 14, and 21. RESULTS This subanalysis included 57 girls (median age, 9 years; 49.1% white, 22.8% black, 17.5% Hispanic) with a diagnosis of ADHD, combined subtype. Twenty-six girls were randomized to receive MAS XR and 31 were randomized to receive atomoxetine. Mean SKAMP deportment and attention subscale scores in the 2 groups were similar at baseline. Mean changes from baseline were significantly greater for MAS XR compared with atomoxetine on the SKAMP deportment score (-0.48 vs -0.04, respectively; P<0.001) and SKAMP attention score (-0.45 vs -0.05; P<0.001). The time course of medication effect, based on change from baseline in SKAMP deportment scores, indicated 12-hour efficacy for MAS XR at hours 2, 4.5, 7, 9.5, and 12 (all time points, P<0.01 vs baseline) but not for atomoxetine. At the end of the study, both treatment groups had a significant increase from baseline in the mean number of math problems attempted and answered correctly (P<0.001). Girls who received MAS XR attempted significantly greater numbers of problems compared with those who received atomoxetine (P=0.04). Both MAS XR and atomoxetine were well tolerated. The most frequently occurring treatment-related adverse events in girls receiving MAS XR were decreased appetite (40.7%), upper abdominal pain (29.6%), insomnia (25.9%), and headache (14.8%). The most frequently occurring treatment-related adverse events in girls receiving atomoxetine were somnolence (28.1%), upper abdominal pain (15.6%), vomiting (15.6%), nausea (12.5%), and decreased appetite (12.5%). CONCLUSION This post hoc analysis in a subpopulation of girls with ADHD, combined subtype, found that 18-day treatment with MAS XR was significantly more effective than atomoxetine in terms of ratings of classroom behavior, attention, and academic productivity.

Abstract
Addiction and addiction-related behaviour increased during the past decades. Several substances with psychoactive attributes, like opioids, cocaine or alcohol, can lead to dependence with physical and/or mental symptoms. In addition to substance-related addiction, non-substance-related dependence requires special attention. Increasing numbers of workaholics and patients suffering from internet-addiction, gambling or eating-disorders can be observed. To meet international treatment standards for addiction, diversification of therapy is necessary and, additionally, gender-related aspects in development and treatment of dependence and addiction-related behaviour are essential for state-of-the-art therapy of this patient population.

Abstract
The identification of reliable and valid means for evaluating the effectiveness of school-based treatments and completing diagnostic evaluations of middle school aged students are needed. The present study examined the inter-rater agreement of teacher ratings and the relationship between ratings and observational data in a middle school setting. The data are interpreted in the context of differences between a secondary and elementary school setting. Teacher ratings and observational data were collected regularly over the course of two academic years for middle school students diagnosed with ADHD. The results indicate low rates of inter-rater agreement as well as low rates of agreement between teachers and observational data, and between observational data collected in different classrooms. Inter-rater agreement was lowest in late fall and gradually increased over the second half of the year. Implications for conducting treatment outcome evaluations of school-based treatment programs and diagnostic evaluations are discussed.

Abstract
Although animals cannot be used to study complex human behaviour such as language, they do have similar basic functions. In fact, human disorders that have animal models are better understood than disorders that do not. ADHD is a heterogeneous disorder. The relatively simple nervous systems of rodent models have enabled identification of neurobiological changes that underlie certain aspects of ADHD behaviour. Several animal models of ADHD suggest that the dopaminergic system is functionally impaired. Some animal models have decreased extracellular dopamine concentrations and upregulated postsynaptic dopamine D1 receptors (DRD1) while others have increased extracellular dopamine concentrations. In the latter case, dopamine pathways are suggested to be hyperactive. However, stimulus-evoked release of dopamine is often decreased in these models, which is consistent with impaired dopamine transmission. It is possible that the behavioural characteristics of ADHD result from impaired dopamine modulation of neurotransmission in cortico-striato-thalamo-cortical circuits. There is considerable evidence to suggest that the noradrenergic system is poorly controlled by hypofunctional α2-autoreceptors in some models, giving rise to inappropriately increased release of norepinephrine. Aspects of ADHD behaviour may result from an imbalance between increased noradrenergic and decreased dopaminergic regulation of neural circuits that involve the prefrontal cortex. Animal models of ADHD also suggest that neural circuits may be altered in the brains of children with ADHD. It is therefore of particular importance to study animal models of the disorder and not normal animals. Evidence obtained from animal models suggests that psychostimulants may not be acting on the dopamine transporter to produce the expected increase in extracellular dopamine concentration in ADHD. There is evidence to suggest that psychostimulants may decrease motor activity by increasing serotonin levels. In addition to providing unique insights into the neurobiology of ADHD, animal models are also being used to test new drugs that can be used to alleviate the symptoms of ADHD.

Abstract
OBJECTIVE To examine gender differences in attention-deficit/hyperactivity disorder ("ADHD") symptom comorbidity with "oppositional defiant disorder", "conduct disorder", "separation anxiety disorder", "generalized anxiety disorder", speech therapy, and remedial reading in children. METHOD From 1994 to 1995, data from a large sample (N = 4,371) of twins and siblings studied in the Australian Twin ADHD Project were obtained by mailed DSM-IV-based questionnaires, investigating patterns of comorbidity in the three subtypes of "ADHD": "inattentive", "hyperactive/impulsive", and "combined". A total of 1,550 questionnaires were returned (87%) over the next 12 to 18 months. RESULTS Analysis of variance showed significant between-group differences in males and females for inattention and hyperactive/impulsive symptom counts with higher rates of "oppositional defiant disorder" and "conduct disorder" in males, and higher rates of "separation anxiety disorder" in females indicating internalizing disorders are more common in females and externalizing disorders are occurring more often in males. Differences were found between the "ADHD" subtypes and the no ADHD category for all comorbid conditions, for both males and females. Children without ADHD consistently had fewer symptoms, while children with the combined subtype showed consistently more comorbid symptoms indicating a strong relationship between high rates of externalizing symptoms and high rates of internalizing symptoms. Gender differences in speech therapy were significant only for the children without ADHD. The rates of "separation anxiety disorder" were higher in females with the "inattention" subtype and the rate of "generalized anxiety disorder" higher for females with the "combined" subtype, indicating that the subtypes of ADHD were associated with these internalizing disorders in different ways. CONCLUSIONS Although comorbidity differs among ADHD subtypes, there were no significant gender differences in comorbidity for externalizing disorders. Inattentive girls may present with anxiety. Clinical approaches for both males and females should be sensitive to possible language and reading problems.

Abstract
OBJECTIVE To examine gender differences among children meeting symptom criteria for DSM-IV attention-deficit/hyperactivity disorder (ADHD) identified in a nationally representative sample of Australian children. METHOD From 2,404 children aged 6 to 13 years, 225 boys and 99 girls with ADHD symptoms were identified using the parent version of the Diagnostic Interview Schedule for Children and compared on parent reports of children's behavioral problems and impairment. RESULTS When ADHD types were collapsed into a single group, boys and girls did not differ on core symptoms, comorbidity, and impairment with the exception that girls rated higher on somatic complaints and boys had poorer school functioning. However, gender patterns were found to vary across ADHD type on impairment measures of social problems, schoolwork difficulties, and self-esteem, with boys being generally rated as more impaired in the combined and hyperactive-impulsive groups but equally or less impaired in the inattentive group. CONCLUSIONS The findings suggest the possibility of gender-specific risks associated with high levels of inattentive and hyperactive-impulsive symptoms indicating that ADHD subtype membership should be considered when conducting ADHD gender comparisons.

Abstract
Zusammenfassung. In der vorliegenden Untersuchung wird das Unterrichtsverhalten einer Gruppe von klinisch auffälligen Kindern mit Aufmerksamkeitsdefizit-/Hyperaktivitätsstörungen (ADHS) mit dem Verhalten unauffälliger Kinder verglichen. Die Auswahl der aufmerksamkeitsgestörten/hyperaktiven Kinder erfolgte aus einer Grundgesamtheit von 569 Grundschülern anhand von DSM III-R Kriterien (Lehrerbeurteilung) und der Teacher Rating Scale ( Conners, 1969 ). 55 derart auffällige Kinder wurden mit einer Stichprobe von 55 Kindern ohne ADHS (Kontrollgruppe) parallelisiert (matched pairs). Das Unterrichtsverhalten wurde anhand des Münchner Aufmerksamkeitsinventars (MAI; Helmke, 1988 ; Helmke & Renkl, 1992 ) beobachtet. Dieses Instrument erfasst sowohl negative als auch angemessene, unterrichtsförderliche Verhaltensweisen sowie den Unterrichtskontext (z. B. mehr oder weniger stark strukturierte Situationen). Ein Vergleich der beiden Gruppen zeigt, dass sich aufmerksamkeitsgestörte und nicht-aufmerksamkeitsgestörte Grundschüler deutlich unterscheiden. Die auffälligen Kinder erweisen sich in allen Verhaltenskategorien als aktiver und störender und zeichnen sich vor allem durch einen Mangel an anforderungskonformen Verhaltensweisen aus. Die Analyse der Kontextbedingungen weist darauf hin, dass unterschiedliche Kontexte durchaus einen Einfluss auf das Verhalten der Kinder im Unterricht haben; allerdings zeigen sich keine differenziellen Effekte für ADHS- und Kontrollkinder. Die Korrelationen zwischen Lehrerurteilen und dem beobachteten Unterrichtsverhalten sind durchgehend signifikant, wobei das anforderungsgemäße Unterrichtsverhalten am höchsten mit dem Lehrerurteil korreliert und einen bedeutsamen Prädiktor für das Lehrerurteil darstellt.

Abstract
Limbic system functioning is integral to the control and modulation of affect, motivation, reward, and memory. Neuropsychiatric disturbances involving disruptions in these cognitive and emotional dimensions exhibit different prevalence rates for men and women. Gender-specific differences in this integrated brain area may therefore be important in understanding both normal behavioral functioning and the etiologic underpinnings of neuropsychiatric disorders. To further explore such differences in limbic system function, we assessed regional cerebral blood flow, by SPECT, in men and women following the administration of procaine. Procaine is a local anesthetic that preferentially stimulates limbic structures. Psychiatrically and medically healthy, age-matched women (n = 15, 33.2 +/- 6.9 years) and men (n = 15, 32.8 +/- 6.9 years) were administered 1.38 mg/kg procaine or saline intravenously in two separate sessions. Using voxel-based analyses (P < 0.001), males significantly activated the bilateral insular cortex following procaine, whereas females more strongly activated the bilateral anterior and mesial temporal cortex. Both groups demonstrated significant anterior cingulate activation. Subjective responses to procaine did not significantly differ between the men and women. To our knowledge, this is the first report demonstrating gender-specific responses in limbic activation following a pharmacologic challenge. These findings suggest that men and women can activate different limbic structures following the same provocative pharmacologic stimulus, despite sharing a similar subjective experience. Studies assessing pharmacologic challenges of limbic system structures should consider gender as a critical variable in assessing biologic responsiveness.

Abstract
Attention-deficit hyperactivity disorder (ADHD) is one of the most common chronic conditions of childhood, with adverse consequences that persist through adolescence into adulthood. Thus, the burden of illness associated with ADHD is high for affected individuals, their families, and society at large. This article reviews available information about ADHD-associated utilisation of healthcare resources, direct medical costs, and the costs or cost effectiveness of pharmacological interventions. Published estimates suggest that direct medical costs for youth with ADHD are approximately double those for youth without ADHD. Cross-sectional studies suggest that ADHD-associated incremental costs are highest for mental health services and pharmaceutical costs, and are greatest for youth with comorbid psychiatric conditions and for those being treated with stimulant medication. To guide relevant clinical and health policy, additional research is warranted on the following: source of increased costs observed among persons with ADHD; patient characteristics of those accruing high medical costs; and the long-term effect of ADHD treatment on direct and indirect costs.

Abstract
As pressure increases for the demonstration of effective treatment for children with mental disorders, it is essential that the field has an understanding of the evidence base. To address this aim, the authors searched the published literature for effective interventions for children and adolescents and organized this review as follows: (1) prevention; (2) traditional forms of treatment, namely outpatient therapy, partial hospitalization, inpatient treatment, and psychopharmacology; (3) intensive comprehensive community-based interventions including case management, home-based treatment, therapeutic foster care, and therapeutic group homes; (4) crisis and support services; and (5) treatment for two prevalent disorders, major depressive disorder and attention-deficit hyperactivity disorder. Strong evidence was found for the treatment of attention-deficit hyperactivity disorder, depression, anxiety, and disruptive behavior disorders. Guidance from the field relevant to moving the evidence-based interventions into real-world clinical practice and further strengthening the research base will also need to address change in policy and clinical training.
