This study examines the clinical utility of behavior ratings made by nonclinician examiners during assessments of preschool children with Attention-Deficit/Hyperactivity Disorder (AD/HD). Matched samples of children with (n = 127) and without (n = 125) AD/HD were utilized to test the internal, convergent, concurrent, and incremental validity of ratings completed by examiners on the Hillside Behavior Rating Scale (HBRS). Results indicated that HBRS ratings were internally consistent, possessed sufficient interrater reliability, and were significantly associated with parent and teacher reports of AD/HD when controlling for age, gender, intelligence, and symptoms of other psychopathology. HBRS ratings also were significantly associated with other measures of functioning, and provided a significant increment in the prediction of impairment over parent and teacher report alone. These findings suggest that behavioral ratings during testing provide a unique source of clinical information that may be useful as a supplement to parent and teacher reports. [ABSTRACT FROM AUTHOR]

The question asked in this study of 70 clinically referred 6- to 12-year-old boys with behavior problems was whether or not childhood inattention-overactivity and aggression are transmitted specifically from biological fathers to sons. Fathers' self-reported childhood inattention-overactivity on a retrospectively valid measure was exclusively associated with parents' ratings of their sons' current attention problems on the Mothers' Operational Measure for Subgrouping (MOMS), the Revised Child Behavior Checklist (RCBCL), and an approximated DSM-IV inattention dimension. Fathers' self-reported childhood aggression was not associated with ratings of their sons' aggression on the MOMS or DADS (a parallel instrument for fathers), nor on DSM-III oppositional or conduct disorder dimensions, but it was exclusively associated with RCBCL ratings of sons' aggressive and delinquent behavior. None of the nonspecific correlations (father inattention-overactivity with son aggression or father aggression with son inattention-overactivity) was significant. [ABSTRACT FROM AUTHOR]

The article presents a study on the relationship of familial alcoholism in anorexia nervosa. The study aims to relate the role of alcohol in the development of anorexia nervosa among family members. It also cited the conviction that alcohol and drugs may be used as substitutes or diversions for the suppression of normal appetite. To affirm this conviction, an investigation on the background of familial alcoholism in patients with anorexia nervosa was conducted. The study discloses that most patients with anorexia nervosa do not have parents or relatives indulged to alcoholism. Yet, it is still recommended that the rising incidence of alcoholism in the parents of anorexia nervosa patients must undergo personal interview.

Objective: To examine associations between childhood treatment with methylphenidate (MPH) and adult height and weight.Method: Subjects were 97 boys, aged 4 to 12 years, with behavior problems who were (1) referred to a child psychiatry outpatient clinic, (2) treated clinically with MPH for an average of 36 months, and (3) reevaluated between ages 21 and 23 years. Hierarchical analyses predicted adult height and weight from sets of non-medication and medication-related variables.Results: Medicated subjects' age, height, and parental socioeconomic status (SES) at referral predicted 44.8% of variation in adult height. Medicated subjects' birth weight, age, height and weight at referral, and parental SES predicted 61.8% of variation in adult weight. With these non-medication variables held constant, initial nausea and vomiting side effects predicted 4.4% incremental variation in adult height, and MPH maintenance dose predicted 3.2% incremental variation in adult weight.Conclusions: Medicated individuals who had attained their final stature did not differ in average height or weight from family, community, or unmedicated controls. Most aspects of medication were not associated with adult height or weight. In some individuals, nausea and vomiting side effects and treatment with higher doses of MPH were associated with adult growth decrements. [ABSTRACT FROM AUTHOR]

Lahey and Waldman proposed a developmental propensity model in which three dimensions of children's emotional dispositions are hypothesized to transact with the environment to influence risk for conduct disorder, heterogeneity in conduct disorder, and comorbidity with other disorders. To prepare for future tests of this model, a new measure of these dispositions was tested. Exploratory factor analysis of potential items was conducted in a sample of 1,358 participants 4 to 17 years of age. Confirmatory factor analyses then confirmed the three dispositional dimensions in a second sample of 2,063 pairs of 6- to 17-year-old twins. Caretaker ratings of the dispositional dimensions were associated as predicted with symptoms of conduct disorder and other psychopathology. In a third sample, caretaker ratings of each disposition correlated uniquely with relevant observational measures of child behavior and unintentional injuries. These findings provide initial support for the new dispositional measure.

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.

Despite important clinical and nosological implications, the comorbidity of oppositional defiant disorder (ODD) and generalized anxiety disorder (GAD) has received little attention. A clinic-based sample of 243 boys (ages 6-10 years), their parents, and teachers participated in an evaluation that involved assessments of behavioral, academic, and family functioning. ODD and GAD symptom groups were defined using various combinations of mother and teacher reports. ODD symptom groups were associated with conduct disorder symptoms, and GAD symptom groups with major depressive disorder symptoms, regardless of rater. Attention deficit/hyperactivity disorder (ADHD) symptoms were associated with ODD and GAD symptom groups; however, covarying ADHD symptoms altered few findings. The ODD + GAD symptom groups were associated with higher rates of co-occurring symptoms and risk factors within (source-specific syndromes) and across (cross-informant comorbidity) informants.

Retrospective childhood attention-deficit/hyperactivity disorder (ADHD) symptoms are required to diagnosis adult ADHD, but the validity of self-rated symptoms across time is questionable. Here, boys with ADHD-related problems, their brothers without ADHD, and former schoolmates rated themselves during young adulthood for ages 9, 14, and 19. Brothers rated probands retrospectively at the same ages. The young adults referred as children for ADHD (a) acknowledged childhood symptoms; (b) described improvement over time; (c) did not differ from brothers or controls on most self-ratings of young adult symptoms; (d) rated themselves as more symptomatic at age 9, but less symptomatic at age 19, than their brothers rated them; and (e) agreed only to some degree with brothers' ratings of probands' aggression (median correlation = .22). Probands' ratings showed limited agreement with judges' symptom ratings (median correlation = .16) and young adult follow-up examiners' ratings (median correlation = .14). These findings are not accounted for solely by changes in informants, nor by the course of ADHD psychopathology. They suggest some stability but limited internal consistency and validity for retrospective ADHD ratings by probands and brothers., ((PsycINFO Database Record (c) 2007 APA, all rights reserved).)

Associations between dopamine transporter (DAT1) variable number tandem repeats (VNTR), genotypes, and disruptive behavior were examined in an 8-year longitudinal study of children (n = 183). Half of the children met criteria for attention-deficit/hyperactivity disorder (ADHD) at 4-6 years and half were non-referred comparison children. Consistent with several studies, the non-additive association for the 10-repeat allele was significant for hyperactivity-impulsivity (HI) symptoms. However, consistent with other studies, exploratory analyses of the non-additive association of the 9-repeat allele of DAT1 with HI and oppositional defiant disorder (ODD) symptoms also were significant. The inconsistent association between DAT1 and child behavior problems in this and other samples may reflect joint influence of the 10-repeat and 9-repeat alleles., ((c) 2006 Wiley-Liss, Inc.)

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.

Objective: To examine differences in risk factors and comorbid conditions for oppositional defiant disorder (ODD) symptom groups in a sample of 248 elementary schoolboys (ages 6-10) recruited from 1994 to 1996., Method: The boys and their mothers received multiple assessments of cognitive, behavioral, academic, and family functioning, including a clinic-based evaluation in Stony Brook, NY. ODD was defined using four different strategies for aggregating data from mother and teacher reports of DSM-IV symptoms., Results: Source-specific ODD symptom groups had better internal validity and were more differentiated than groups defined using the other strategies. The mother-defined ODD symptom group (ODD/M) had higher levels of maternal detachment than the teacher-defined symptom group (ODD/T), and the ODD/T group had more social problems than the ODD/M group. The classification agreement group (ODD/M + T) evidenced higher levels of sensation-seeking, maternal control, and comorbid symptoms than the ODD/M and ODD/T groups. Controlling for co-occurring attention-deficit/hyperactivity disorder and conduct disorder symptoms altered some of the relationships among ODD, comorbid symptoms, and psychosocial correlates., Conclusions: Patterns of co-occurring psychiatric symptoms and psychosocial correlates of ODD symptom groups varied depending on the rater(s) used to determine group membership. Results support continued research into source specificity for conceptualizing ODD.

Context: The DSM-IV definition of attention-deficit/hyperactivity disorder (ADHD) distinguished 3 subtypes that had not been extensively studied., Objective: To determine whether the ADHD subtypes are stable enough over time to be valid., Design: Longitudinal study with a greater-than 89% retention rate in 7 assessments over 8 years., Setting: Outpatient clinics., Participants: Volunteer sample of 118 4- to 6-year-olds who met DSM-IV criteria for ADHD, including impairment in 2 settings in at least 1 assessment., Main Outcome Measure: Meeting DSM-IV criteria for the subtypes of ADHD during years 2 through 8., Results: The number of children who met criteria for ADHD declined over time, but most persisted. Children who met criteria for the combined subtype (CT, n = 83) met criteria for ADHD in more subsequent assessments than children in the predominantly hyperactive-impulsive subtype (HT, n = 23). Thirty-one (37%) of 83 CT children and 6 (50%) of 12 children in the predominantly inattentive subtype (IT) met criteria for a different subtype at least twice in the next 6 assessments. Children of the HT subtype were even more likely to shift to a different subtype over time, with HT children who persisted in ADHD mostly shifting to CT in later assessments. The subtypes exhibited consistently different mean levels of hyperactive-impulsive symptoms during years 2 through 8 that corresponded with their initial subtype classifications, but initial subtype differences in inattention symptoms diminished in later years., Conclusions: In younger children, the CT and IT may be stable enough to segregate groups for research, but they seem too unstable for use in the clinical assessment of individual children. Children rarely remain in the HT classification over time; rather, they sometimes desist from ADHD but mostly shift to CT in later years. Using continuous ratings of hyperactivity-impulsivity symptoms as a diagnostic qualifier should be considered as an alternative to classifying nominal subtypes of ADHD in DSM-V.

Short measures of child inattention-overactivity (IO), aggression-defiance (AG), and anxiety-depression or emotionality (EM) derived through a double validation procedure are administered to mothers of 243 clinic-referred suburban New York boys between 6 and 10 years of age. Mother-rated IO is uniquely related to poor performance on cognitive and achievement tests; observed inattentive, hyperactive, and impulsive behaviors in a restricted academic setting; less father education and lower family income; and most mother-reported impairments and treatment use. Mothers of high-IO boys describe themselves and their sons as having similar childhood symptoms. AG is uniquely related to child-reported disruptive behavior and sensation seeking, many measures of family conflict and negative parenting styles, and mother-reported symptom pervasiveness and number of treatments. EM is uniquely related only to poorer cognitive and achievement test performance, living with one parent, parents who considered themselves too busy, and fewer friends. Each dimension also is associated with parallel teacher-rated factors.

Objective: Predictive validity is a fundamental consideration in evaluating the DSM-IV diagnostic criteria for attention deficit hyperactivity disorder (ADHD), particularly for younger children., Method: The authors conducted four annual assessments of ADHD and functional impairment using multiple informants in 255 probands and matched comparison children who were 4-6 years old in wave 1., Results: Nearly all children who met full criteria for ADHD in wave 1 met full criteria for ADHD over the next 3 years and continued to display marked functional impairment relative to comparison children, even when intelligence, co-occurring psychopathology, and demographic characteristics were controlled., Conclusions: 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.

Background: This study examines differences between the three subtypes of attention-deficit/hyperactivity disorder (ADHD), inattentive (I), hyperactive-impulsive (H), and combined (C), in a heterogeneous sample of 248 boys (ages 6 to 10 years) with emotional and behavioral problems who were recruited for participation in a diagnostic study., Method: The boys and their mothers participated in an extensive evaluation that involved multiple assessments of cognitive, behavioral, academic, and family functioning. ADHD subtypes were defined on the basis of teacher alone, mother alone, and mother/teacher ratings of DSM-IV symptoms., Results: Results indicated ADHD symptom groups showed a differential pattern of impairment socially (H,C>I) and cognitively (I,C>H). The C and H groups were the most and least impaired overall, respectively, and all subtypes were differentiated from the nonADHD clinical control or NONE (N) group in a manner consistent with the primary findings. External validation of group differences was limited, and there were marked inconsistencies in the pattern of findings depending on how groups were defined. For the most part, although the mother/teacher grouping strategy (compared with either alone) captured a greater diversity of differences between subtypes, it also obscured some., Conclusions: Observed findings are consistent with the notion that mothers and teachers interpret symptom statements in terms of behaviors that are most relevant for their daily concerns.

Examined reliability and validity of the parent version of the Child Symptom Inventory (CSI-4) in 247 boys between 6.0 and 10 years 11 months old referred for evaluation of behavioral and emotional problems. The CSI-4 is a behavior rating scale whose items correspond to the symptoms of disorders defined by the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994). Results indicated satisfactory internal consistency reliability, test-retest reliability, and temporal stability over a 4-year period for most symptom categories. CSI-4 ratings converged and diverged in a theoretically consistent pattern with respective scales of the Child Behavior Checklist (CBCL; Achenbach, 1991a) and the Diagnostic Interview for Children and Adolescents-Revised-Parent Version (DICA-P; Reich, Shayka, & Taibleson, 1991). Discriminant validity was established in that boys with specific DICA-P diagnoses received significantly higher corresponding CSI-4 parent symptom ratings than boys not so diagnosed. Clinical utility (sensitivity, specificity, positive predictive power, negative predictive power) was evaluated for screening cutoffs based on categorical (DSM-IV) and dimensional (normative distribution of Symptom Severity scores) scoring methods.

Examined sex differences in a mostly clinic-referred sample of 127 children (22 girls, 105 boys) who met Diagnostic and Statistical Manual of Mental Disorders (4th ed.; [DSM-IV], American Psychiatric Association, 1994) criteria for attention deficit hyperactivity disorder (ADHD) and 125 comparison children (24 girls, 101 boys) matched on age, sex, and race-ethnicity. Children in both groups ranged in age from 3 years, 10 months to 7 years, 0 months. Both girls and boys who met criteria for ADHD were more impaired than same-sex controls on a variety of measures when intelligence and other types of psychopathology were controlled. Teachers reported that boys with ADHD were more inattentive and more hyperactive/impulsive than girls with ADHD. These findings suggest that the diagnosis of ADHD is valid for both girls and boys in this young age range. Young girls and boys who meet DSM-IV criteria for ADHD are more similar than different, but boys tend to display more symptoms of ADHD, particularly in school.

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.

This study examined the contributions of childhood symptom dimensions and aspects of methylphenidate (MPH) treatment to the prediction of young adult outcomes in boys who were referred to a child psychiatry outpatient clinic. They were diagnosed with hyperkinetic reaction of childhood/minimal brain dysfunction, and given MPH for an average of 30 months. Including significant effects and statistical trends, childhood Inattention-Over-activity was uniquely associated with fewer than 10% of adult outcomes such as schizotypic features, impairment on the Global Assessment Scale (GAS), and unemployment. Childhood aggression was uniquely associated with 38% of adult outcomes such as lifetime diagnoses of major depression, drug abuse disorder, and antisocial personality disorder; MMPI PD, PA, and SC scores; and six additional measures of adult impairment and life circumstances-extending external validation of the two-factor model to young adulthood. For 20 young adult outcomes (63%), aspects of childhood treatment with MPH had no lasting effects. For one adult outcome (3%), a lasting negative effect of childhood drug treatment was found; better initial response to medication was associated with not graduating from high school. For 11 young adult outcomes (34%), however, aspects of childhood MPH treatment had positive effects that lasted long after treatment was discontinued. Higher dosage was associated with fewer diagnoses of alcoholism or suicide attempts. Better response to medication was associated with lower MMPI D scores and better social functioning. Longer medication duration was associated with fewer schizotypic features, lower MMPI MA scores, higher WAIS Performance and Full Scale IQs, and better WRAT Reading and Arithmetic performance.

Objective: Little is known about the validity of the diagnosis of attention-deficit/hyperactivity disorder (ADHD) in young children. Moreover, the results of the DSM-IV field trials raised concerns that inclusion of the new predominantly hyperactive-impulsive type of ADHD in DSM-IV might increase the likelihood of the diagnosis being given to active but unimpaired preschool and primary school children., Method: The validity of DSM-IV criteria for each subtype of ADHD was evaluated in 126 children, aged 4 through 6 years, and 126 matched comparison children. Probands and controls were classified by using structured diagnostic interviews of the parent and a DSM-IV checklist completed by the teacher., Results: Children who met DSM-IV criteria for each subtype of ADHD according to parent and teacher reports differed consistently from controls on a wide range of measures of social and academic impairment, even when other types of psychopathology and other potential confounds were controlled., Conclusions: When diagnosed by means of a structured diagnostic protocol, all three DSM-IV subtypes of ADHD are valid for 4- through 6-year-old children in the sense of identifying children with lower mean scores on measures of adaptive functioning that are independently associated with ADHD.

Validity of the distinction between oppositional disorder (OD) and attention deficit disorder with hyperactivity (ADDH) was examined in a sample of 6- to 12-year-old boys with behavior problems. Problem identification, cognitive/attentional, family context, and behavioral symptom differences were examined among nine boys with OD only, 20 with ADDH, 40 with comorbid OD and ADDH, and 28 with neither disruptive behavior disorder. Systematic comparisons of groups including and excluding the OD and ADDH diagnoses were undertaken to determine the existence of pure OD and pure ADDH disorder effects. The most consistent result was the lack of evidence for either pure OD or pure ADDH effects. Most of the significant findings reflected differences between the nondisruptive (neither) and comorbid groups. The results support the importance of comorbidity, but they provide little support for disorder-specific distinctions between oppositional and attention deficit disorders.

The Teacher Approval-Disapproval Scale was administered to three groups of elementary school boys: those considered by a teacher as hyperactive and referrable; those considered as among the most active but not referrable; and normoactive classmates. The three groups of boys differed significantly in their responses to 8 of 11 individual scale items, which ask the child about the amount of teacher approval and disapproval directed toward himself personally or about the frequency of his own happiness and unhappiness in the classroom. The three groups of boys differed significantly on only 2 of 11 countepart class items, which ask the child about teacher behaviors toward the class as a whole or about the happiness and unhappiness of the entire class. The hyperactive boys said they received significantly less approval from m teachers from academic, motivational, and social behaviors than did the normoactive boys and significantly more general disapproval. The present study is among the few that report differences between hyperactive and comparison groups on self-report questionnaires. The results suggest that what appears to be greater teacher disapproval of boys than of girls may in fact be simply greater teacher disapproval of children with disruptive behavior problems, most of whom are boys.

The authors report on a special section of a Children's Museum which is designed to involve the child and parent in actively learning about vocal function. This approach is recommended as an excellent way to promote interest in healthy vocal function.

An ECG/EEG common-mode rejection ratio analyzer is discussed and its method of operation is analyzed. In addition to easily performed common-mode rejection ratio tests, this instrument also can perform linearity, frequency response and sweep-speed tests. Because of the complexity of the standard method for performing common-mode rejection ratio tests, many hospitals are omitting this test or employing alternative common-mode rejection tests. However, the ease of this new device facilitates its use in performing common-mode rejection tests.

This study compares the short-term effects of methylphenidate and of teacher consultation on the on-task behavior of diagnosed hyperkinetic outpatient boys and selected classmates. Statistically significant treatment effects were found for both drug-treated and behaviorally treated hyperkinetic boys; the size of these effects did not differ between the two types of treatment. Within the behavioral group, the treatment effect spilled over, so that there was also a significant treatment effect on overactive classmates of the behaviorally treated hyperkinetic children and a trend toward a significant treatment effect on their average classmates. Some implications of the findings are discussed.

The first heuristic description of the hyperkinetic impulse disorder made its appearance in the literature just over twenty years ago. Although there are many who are made restless and irritable by continuing ambiguities and controversies surrounding the hyperkinetic syndrome, the past two decades have brought considerable maturation in our knowledge of this concept. The present paper sketches the state of the art in regard to hyperkinesis, and draws conclusions about directions for both research and clinical work.

A computed tomographic (CT) brain scan study was conducted in 24 young males treated and followed up for hyperactivity since childhood. Compared to 27 matched controls, adults with a history of hyperactivity had a significantly greater frequency of cerebral atrophy. No differences in cerebellar atrophy frequency or in lateral cerebral ventricle-to-brain ratio (VBR) were found. The possible associations of hyperactivity or perhaps stimulant drug treatment to atrophic brain changes are discussed.
