We contrasted a sample of children and adolescents with affective disorders and mental retardation with a comparison group on behavioral symptoms, associated diagnoses, and psychopharmacologic treatment. Fifty consecutive patients with both impaired intellectual functioning and at least one affective disorder admitted to a psychiatric inpatient unit for children and adolescents with developmental disabilities and psychiatric disorders were matched to a group of 50 inpatients without depression. Behavioral symptoms such as suicidal ideation or gestures, crying, irritability, sleep problems, agitation, mood lability, and social withdrawal/isolation occurred significantly more often in the affective group than in the comparison group. Aggression, however, was the most frequent behavior concern for both groups, whereas disruption/destruction was identified significantly more often in the comparison group. Regarding Axis I diagnoses, the comparison group was more often identified with externalizing disorders (ADHD, ODD), though there was a high rate of comorbidity in the affective disorder group. The behavioral symptoms used to diagnosis normally developing children and adolescents appear to be applied in making affective disorders diagnoses in this sample of children and adolescents with mental retardation.

The study consisted of evaluating 80 out-patients for DSM-IV diagnoses and giving 75 mg trazodone for four months to children aged 9-13 who fulfilled DSM-IV criteria for Major Depressive Disorder (n = 22); Major Depressive Disorder and Generalized Anxiety Disorder (n = 24), Major Depressive Disorder and Learning Disorder NOS (n = 24); Major Depressive Disorder and Oppositional Defiant Disorder (n = 10). They were followed up weekly by a psychiatrist blind to the original evaluations and to the precise purpose of the study. Trazodone emerges as safe and effective for over 50% of the sample. Those with depression alone and with LD NOS did particularly well, and those with ODD did particularly badly. The presence of psychopathology in the parents was associated with poorer response to trazodone, and life events were also associated with a poor response.

A total of 23 boys met DICA-P manic symptom and clustering criteria in a diagnostic investigation of 233 outpatient boys between ages 6 and 10. In this manic-symptom group, the most frequently endorsed of an average of five manic symptoms were extreme mood changes, difficulty concentrating, feeling too 'up' to sit still, and racing thoughts. Comparison groups were 23 non-manic boys seen next in the investigation and 23 non-manic boys matched to the manic-symptom boys on symptoms of three comorbid disruptive disorders (ADHD, ODD and CD). Manic-symptom boys differed significantly from next-seen boys, but not from matched comorbid boys, in number of oppositional symptoms and pervasiveness of problems. Manic-symptom boys differed significantly from next-seen boys on six of eight mother-rated RCBCL factors. In contrast, manic-symptom and matched comorbid boys did not differ on any of eight RCBCL factors, which suggests that the RCBCL differences can be attributed to shared ADHD, ODD and/or CD. However, manic-symptom and matched comorbid boys tended to differ on RCBCL Anxiety/Depression. On the teacher-rated TRF, manic-symptom boys were rated higher than next-seen boys on four internalizing factors, and higher than matched comorbid boys on two of those factors, including Anxiety/Depression. Thus, manic symptomatology also predicted substantial emotionality, which was not a controlled comorbidity. The findings of this and other studies suggest that there is a mania dimension or syndrome, which may be an indicator of true bipolar disorder--or simply a marker for disruptive comorbidity, behavioral and emotional multimorbidity, or general severity of psychopathology.

This study used data from a completed longitudinal study to examine the effects of methylphenidate on 6-12-year-old boys presumably at risk for bipolar disorder. Of 75 boys referred, diagnosed with hyperkinetic reaction of childhood (minimal brain dysfunction), treated clinically with methylphenidate, and followed as young adults, 23% (the maximorbid or MAX group) had childhood symptoms of irritability and emulated DSM-IV diagnoses of attention deficit hyperactivity disorder (ADHD), plus oppositional defiant or conduct disorder (ODD/CD) and anxiety or depression or both. The remaining boys (the minimorbid or MIN group) had fewer symptoms and disorders. MAX and MIN groups did not differ in rated response to methylphenidate, duration of treatment, clinically determined maintenance doses, concurrent or subsequent treatment with other medications, or other aspects of medication experience. At ages 21-23, individuals with bipolar-related lifetime diagnoses (adult mania, hypomania, or cyclothymia) did not differ from those without bipolar-related diagnoses in any aspect of early methylphenidate treatment history. These findings indicate that ADHD boys with symptoms suggesting childhood mania do not respond differently to methylphenidate than boys without such symptoms, and there is no evidence here that methylphenidate precipitates young adult bipolar disorders in susceptible individuals.

The use of DSM-IV based questionnaires in child psychopathology is on the increase. The internal construct validity of a DSM-IV based model of ADHD, CD, ODD, Generalised Anxiety, and Depression was investigated in 11 samples by confirmatory factor analysis. The factorial structure of these syndrome dimensions was supported by the data. However, the model did not meet absolute standards of good model fit. Two sources of error are discussed in detail: multidimensionality of syndrome scales, and the presence of many symptoms that are diagnostically ambiguous with regard to the targeted syndrome dimension. It is argued that measurement precision may be increased by more careful operationalisation of the symptoms in the questionnaire. Additional approaches towards improved conceptualisation of DSM-IV are briefly discussed. A sharper DSM-IV model may improve the accuracy of inferences based on scale scores and provide more precise research findings with regard to relations with variables external to the taxonomy.

Clinic-referred teens (ages 12-19) with ADHD and ODD (N = 101) were compared to community control (CC) teens, equated for age and sex, (N = 39) on a variety of psychological tasks assessing executive functioning (EF), temporal reward discounting, and time estimation and reproduction. A factor analysis reduced the EF measures to three dimensions, representing CPF Inattention, Working Memory, and CPT Inhibition. Results indicated that the ADHD group had significantly more CPT Inattention than the CC group. No differences were found for Working Memory or CPT Inhibition. The ADHD group displayed significantly greater temporal discounting of delayed hypothetical monetary rewards relative to immediate ones and manifested more impaired time reproduction, but not time estimation, than did the CC group. Main effects for level of IQ were found only on the Working Memory factor and largely did not interact with the group factor otherwise. The group differences in CPT Inattention, temporal discounting, and time reproduction were not a function of level of comorbid oppositional defiant disorder, delinquency, or anxiety-depression. Results are reasonably consistent with past research on EF and sense of time in children with ADHD and extend these findings to the adolescent age group. Problems with working memory and CPT inhibition found in prior studies of children with ADHD, however, were not evident here, perhaps owing to age-related improvements or insufficient task difficulty.

Available research provides compelling evidence that ADHD is associated with significantly increased risks for various adverse outcomes while driving, including increased traffic citations (particularly speeding), motor vehicle crashes for which the driver is at fault, repeated crash occurrences,and more severe crashes as determined from dollar damage and likelihood of bodily injuries from the crash. Not surprisingly, teens and adults with ADHD are more likely to have their licenses suspended and even fully revoked. Research further suggests that these driving risks cannot be accounted for by the comorbid disorders likely to be associated with ADHD, such as ODD, conduct disorder (CD), depression, or anxiety, or by lower than normal levels of intelligence. Recent attempts to study the processes or mechanisms involved in driving in adults with ADHD offer some explanation of how the disorder conveys such increased risks. Driving can be conceptualized usefully as involving at least three or more dimensions or levels, including basic cognitive abilities necessary for driving (operational), actual skills for maneuvering the vehicle in traffic (tactical), and the more executive, goal-directed aspects of driving(strategic). The findings of studies indicate that ADHD interferes with the basic operational components of driving by means of the impairments it produces in attention, resistance to distraction, response inhibition, slower and more variable reaction time, and the capacity to follow rules that may compete with ongoing sensory information. Accumulating evidence also points to a problem in the tactical level of driving, such that those with ADHDrate themselves and are rated by others as employing less safe driving habits during their normal operation of a vehicle than are adults in community control groups. Although this has been more elusive to demonstrate through the use of simple laboratory-based driving simulators. more modern virtual reality driving platforms offer greater promise in providing more realistic appraisals of driving performance and thus more direct evidence of the problems that occur at the tactical level from the disorder. Research has not examined the impact of ADHD at the higher strategic level or goal-directed aspects of driving. But given the mounting evidence that ADHD adversely affects executive functioning in adults, the author and colleagues anticipate that this level also will be found to be impaired in adults with ADHD. Indeed,it recently has been shown that adults with ADHD overestimate their driving abilities relative to normal adults, a problem that likely can be ascribed to more limited self-awareness and related meta-cognitive abilities for self-evaluation arising from the disorder. Although further research on the driving problems posed by ADHD is in order, sufficient evidence exists to warrant focus on possible treatments that may serve to improve these driving problems and reduce the risk for these adverse outcomes. High on the list of such treatments deserving further research and clinical attention is the use of stimulant medication. The more recent noradrenergic reuptake inhibitor. atomoxetine, also may have some promise in this regard. Studies are underway in the author's driving laboratory to see if this is the case. Meanwhile, adults with ADHD and parents of teens with ADHD should be advised about these heightened risks and encouraged to take steps that may reduce them, including the consideration of more graduated licensing for adolescents with ADHD and the possible use of stimulant medication in teens and adults with ADHD while they are operating a motor vehicle.

This study examined whether others (i.e., teachers and parents) and self-appraisals of social competence mediated the relationship between Attention-Deficit/Hyperactivity Disorder (ADHD) and depression. To determine whether age moderated the effects of the mediation, the total sample was divided into younger (under 9) and older (at or above 9 years) age levels. The total sample (age range 6.6 to 11.7 years) was primarily male (194 boys and 52 females) and consisted of 148 children diagnosed with ADHD and 98 community controls. Three central findings were derived from this study. First, there was a strong relationship between ADHD (with and without comorbid ODD/CD) and depression in both younger and older aged children. Among younger children with ADHD, there was no differential influence on the level of depression depending on whether or not ADHD was comorbid with ODD/CD; in contrast, with older children, comorbid ODD/CD had higher levels of depression than was the case for children with ADHD that did not display such comorbidity. Second, with younger children approximately half of the relationship between ADHD (with and without comorbid ODD/CD) and depression was exclusively mediated by others appraisal of social competence. Third, a more complex relationship between ADHD and depression emerged during the later part of the childhood years. As such, the relationship between ADHD, others appraisals of social competence, and depression was further mediated by self-appraisals of social competence. Findings are discussed in terms of developmental theory and theoretical models of childhood depression.

To estimate the prevalence of being well-adjusted in adolescence, boys and girls with (n = 96) and without (n = 126) attention-deficit/hyperactivity disorder (ADHD) were assessed seven times in eight years starting when they were 4-6 years of age. Symptoms of ADHD, ODD/CD, and depression/anxiety in addition to social skills and social preference were gathered using multiple methods and informants. Being well-adjusted was defined by surpassing thresholds in at least four of the five domains. At the 7- and 8-year follow-up, when youth were 11-14 years old, probands were significantly less likely to be well-adjusted relative to age- and ethnicity-matched control children. Only a minority of children with ADHD was well-adjusted in adolescence when emotional, behavioral, and social domains were considered simultaneously. Even when their ADHD symptoms improved over time, most probands exhibited significant impairment 7-8 years after their initial assessment.

8.6% suicidal ideation (SI) was found among 349 urban 6-9 year olds in the top tercile of aggressive-disruptive behavior. SI was associated with more self-reported depression, ODD, conduct problems, and ADHD symptoms (ES 0.70-0.97) and 3.5-5 times more clinically significant symptoms. Parents rated more symptoms in older children associated with SI compared to parents of similar age children without SI, including greater somatic and behavior problems in 8-9 year olds with SI. Parent ratings did not differentiate SI and non-SI in 6-7 year olds. SI frequently co-occurred with thoughts about death. Children described anger, dysphoria and interpersonal conflict as motivators/triggers for SI and worries about safety/health as motivator/triggers for thoughts about death, suggesting that problems managing emotionally challenging situations are a specific factor in initiating SI. Universal and indicated interventions for children to strengthen emotional self-regulation and behavioral control are recommended to complement the current emphasis on suicide prevention among adolescents.
