Mood and anxiety disorders following pediatric traumatic brain injury: a prospective study

Studies utilizing standardized instruments for assessing mood and/or anxiety disorders following pediatric traumatic brain injury have seldom been reported in the literature. Previous reports have largely focused on cognitive impairment, behavioral dysfunction, or adaptive functioning, and have typically relied on parental informants. In this study, children hospitalized for mild (N = 42) and moderate/severe (N = 19) brain injury were assessed 6-months postinjury using the Anxiety disorders Module A and the Mood disorders Module C of the Diagnostic Interview Schedule for Children - IV Revision (DISC-IV). The data collected for the brain injury groups were compared to an orthopedic control group (N = 35). The relationship between a new onset mood and/or anxiety disorder (NOD) and injury severity indices was examined. Sequential logistical regression was also utilized to examine the impact of a brain injury, demographic variables, preinjury psychiatric disturbance, development disorders, litigation status and postinjury environmental stress on emotional outcome. Results indicated a relationship between brain injury and NOD. Multivariate analysis demonstrated that postinjury level of stress and severity of brain injury were the most robust predictors of NOD, accounting for 23% of the variance in the model. These results support the premise that the development of a mood and/or anxiety disorder following pediatric head injury is mediated by multiple determinants. The findings suggest that early psychosocial assessment and interventions aimed at increasing a child's coping may attenuate the emotional consequences of pediatric brain injury.     

Anxiety after severe pediatric closed head injury

OBJECTIVE: To assess the frequency of anxiety symptoms and disorders 1 year after severe pediatric closed head injury (CHI) and to determine the risk factors associated with these postinjury outcomes. METHOD: Ninety-seven subjects were prospectively followed for 1 year after severe CHI (Glasgow Coma Scale Score = 3-8). Assessments of preinjury and 1-year postinjury psychiatric status and psychosocial adversity were conducted. Frequency of anxiety symptoms and disorders 1 year after injury were the outcome measures. Data collection occurred between 1992 and 1996. RESULTS: There was a significant increase in the total number of anxiety symptoms after injury compared with before injury. The most frequent symptoms were overanxious symptoms, followed by obsessive-compulsive symptoms, separation anxiety symptoms, and simple phobia symptoms. There was a trend toward an increase in the frequency of overanxious disorder after injury. Preinjury anxiety symptoms correlated positively with postinjury anxiety symptoms and disorders. Younger age at injury correlated positively with postinjury anxiety symptoms. CONCLUSIONS: One year after severe CHI, children are at risk for a variety of anxiety symptoms and, possibly, overanxious disorder. Preinjury anxiety and younger age at injury are risk factors for these disturbances.     

Mental health in pediatric settings: distribution of disorders and factors related to service use

OBJECTIVES: To examine child psychiatric disorders in pediatric settings and identify factors associated with parents' use of pediatricians as resources concerning emotional/behavioral issues and use of mental health services. METHOD: The sample consists of 5- to 9-year-olds (mean = 7.17 years, SD = 1.41) from a representative sample (N = 1,060) of pediatric practices. Parent interviews included assessments of psychiatric disorders with the Diagnostic Interview Schedule for Children (DISC-R), parental depression/anxiety, possible child abuse, stress, support, and the use of mental health services. RESULTS: The prevalence of any DISC disorder was 16.8%. Parental depression/anxiety and possible child abuse were associated independently with 2- to 3-times higher rates of disorder. Many parents (55%) who reported any disorder did not report discussing behavioral/emotional concerns with their pediatrician. Factors associated with discussing behavioral/emotional issues were the presence of any disorder and financial stress. Factors related to seeing a mental health professional were discussing behavioral/emotional issues with the pediatrician, single parenthood, and stressful life events. CONCLUSIONS: The prevalence rates of disorders in this setting suggest that pediatricians are well-placed to identify and refer children with psychiatric disorders. However, most parents do not discuss behavioral/emotional issues with their pediatrician. Methods for improving rates of identification and referral (e.g., routine screening) are considered.     

Neuroimaging correlates of anxiety after pediatric traumatic brain injury.

BACKGROUND: Anxiety disorders are common after traumatic brain injury (TBI). Data on the neural correlates of these conditions are lacking. This study examines the relationship between brain damage, particularly to the orbitofrontal cortex (OFC) and temporal lobe, and anxiety symptoms and disorders. METHODS: Ninety-five children and adolescents were followed for one year postinjury. Preinjury and one-year postinjury anxiety status were obtained from the parent. Magnetic resonance imaging was performed to evaluate brain lesions. The primary analysis used regression models to determine relationships between brain lesions and anxiety outcomes. As a secondary analysis, previously reported posttraumatic stress disorder (PTSD) data were reanalyzed using similar methods for purposes of comparison. RESULTS: The primary analysis showed that greater volume and number of OFC lesions correlated with decreased risk for anxiety, whereas lesions in other brain areas did not correlate with anxiety. Consistent with prior data, the secondary analysis showed an inverse correlation between OFC damage and PTSD; temporal lobe damage was positively correlated with PTSD. CONCLUSIONS: After pediatric TBI, greater damage to the OFC is associated with decreased risk for anxiety outcomes. Similar to adult data, these findings implicate OFC dysfunction in childhood anxiety. Temporal lobe damage did not correlate with anxiety, in contrast to the findings for PTSD.     

Different psychophysiological and behavioral responses elicited by frustration in pediatric bipolar disorder and severe mood dysregulation

OBJECTIVE: Researchers disagree as to whether irritability is a diagnostic indicator for pediatric mania in bipolar disorder. The authors compared the behavioral and psychophysiological correlates of irritability among children with severe mood dysregulation (i.e., nonepisodic irritability and hyperarousal without episodes of euphoric mood) and narrow-phenotype bipolar disorder (i.e., a history of at least one manic or hypomanic episode with euphoric mood) as well as those with no diagnosis (i.e., healthy comparison children). METHOD: Subjects with severe mood dysregulation (N=21) or narrow-phenotype bipolar disorder (N=35) and comparison subjects (N=26) completed the affective Posner task, an attentional task that manipulated emotional demands and induced frustration. Mood response, behavior (reaction time and accuracy), and brain activity (event-related potentials) were measured. RESULTS: The severe mood dysregulation and narrow-phenotype bipolar disorder groups both reported significantly more arousal than comparison subjects during frustration, but behavioral and psychophysiological performance differed between the patient groups. In the frustration condition, children with narrow-phenotype bipolar disorder had lower P3 amplitude than children with severe mood dysregulation or comparison subjects, reflecting impairments in executive attention. Regardless of emotional context, children with severe mood dysregulation had lower N1 event-related potential amplitude than comparison subjects or children with narrow-phenotype bipolar disorder, reflecting impairments in the initial stages of attention. Post hoc analyses demonstrated that the N1 deficit in children with severe mood dysregulation is associated with oppositional defiant disorder symptom severity. CONCLUSIONS: Results indicate that while irritability is an important feature of severe mood dysregulation and narrow-phenotype bipolar disorder, the pathophysiology of irritability may differ among the groups and is influenced by oppositional defiant disorder severity.     

The relationship between anxiety disorders and physical disorders in the U.S. National Comorbidity Survey

Although depression has clearly been shown to be associated with physical disorders, few studies have examined whether anxiety disorders are independently associated with medical conditions after adjusting for comorbid mental disorders. We examined the relationship between anxiety disorders and a wide range of physical disorders in a nationally representative sample. Data came from the National Comorbidity Survey (N=5,877, range=age 15-54 years, response rate=82.4%). The Composite International Diagnostic Interview [Kessler et al., 1998] was used to make DSM-III-R [American Psychiatric Association, 1987] mental disorder diagnoses. Physical disorders were assessed based on a list of several conditions shown to respondents. All analyses utilized multiple logistic regression to examine the relationship between past-year anxiety disorder diagnosis and past-year chronic physical disorder. Anxiety disorders were positively associated with physical disorders even after adjusting for mood disorders, substance-use disorders, and sociodemographics. Among respondents with one or more physical disorders, a comorbid anxiety disorder diagnosis was associated with an increased likelihood of disability even after adjusting for severity of pain, comorbid mood, and substance use disorders. Among specific anxiety disorders, posttraumatic stress disorder, panic attacks, and agoraphobia were more likely to be associated with specific physical disorders than generalized anxiety disorder, social phobia, or simple phobia. There is a strong and unique association between anxiety disorders and physical disorders. Clinically, the presence of an anxiety disorder among patients with physical disorders may confer a greater level of disability.     

Psychopathology among adults abused during childhood or adolescence: results from the Israel-based World Mental Health Survey

Childhood and adolescence abuse is a risk factor for later psychopathology. We examined the association between the age when sexual (SA) and physical (PA) abuse first occurred and mood and anxiety disorders and their respective age of onset, emotional distress, and sleep disturbances. Data were gathered from the Israel-based component of the World Mental Health Survey (N = 4859). Abuse was elicited by direct questions. Psychiatric disorders were diagnosed with the Composite International Diagnostic Interview, emotional distress with the 12-item General Health Questionnaire, and sleep disturbances by self-report. Multivariate analyses indicated an increased risk for psychopathology among subjects who reported childhood SA and PA. SA was associated with lifetime mood (odds ratio [OR] = 1.7) and anxiety (OR = 2.3) disorders; PA with lifetime anxiety disorder (OR = 2.8); and any abuse with increased risk for lifetime mood (OR = 1.7) and 12-month anxiety disorders (OR = 1.8). Earlier onset of SA or PA was associated with increased risk for later psychopathology.     

Autism spectrum disorder scale scores in pediatric mood and anxiety disorders

Objective:To compare scores on autism spectrum disorder (ASD) symptom scales in healthy youths and youths with mood or anxiety disorders.Method:A total of 352 youths were recruited (107 healthy participants, 88 with an anxiety disorder, 32 with major depressive disorder, 62 with bipolar disorder, and 63 with a mood disorder characterized by severe nonepisodic irritability). Participants received structured psychiatric interviews and parent ratings on at least one of three ASD symptom scales: Children's Communication Checklist, Social Communication Questionnaire, and Social Responsiveness Scale.Results:Relative to healthy youths, youths with mood or anxiety disorders exhibited higher scores on each ASD symptom scale. ASD symptom scale scores also showed an association with impairment severity and attention-deficit/hyperactivity disorder. Among patients with mood disorders but not those with anxiety disorders, consistent, statistically significant associations between diagnosis and ASD symptom scale scores remained even after controlling for potential confounders.Conclusions:Patients with mood disorders exhibit higher scores on ASD symptom scales than healthy youths or youths with anxiety disorders. These data should alert clinicians to the importance of assessing ASD symptoms to identify social reciprocity and communication deficits as possible treatment targets in pediatric mood and anxiety disorders.     

Comparing anxiety disorders and anxiety-related traits in bipolar disorder and unipolar depression

The frequent comorbidity of anxiety disorders and mood disorders has been documented in previous studies. However, it remains unclear whether specific anxiety traits or disorders are more closely associated with unipolar major depression (MDD) or bipolar disorder (BPD). We sought to examine whether MDD and BPD can be distinguished by their association with specific types of anxiety comorbidity. Individuals with a primary lifetime diagnosis of either bipolar disorder (N=122) or major depressive disorder (N=114) received diagnostic assessments of anxiety disorder comorbidity, and completed questionnaires assessing anxiety sensitivity and neuroticism. The differential association of these anxiety phenotypes with MDD versus BPD was examined with multivariate modeling. Panic disorder and generalized anxiety disorder (GAD) specifically emerged amongst all the anxiety disorders as significantly more common in patients with BPD than MDD. After controlling for current mood state, anxiety sensitivity and neuroticism did not differ by mood disorder type. This study supports prior research suggesting a specific panic disorder-bipolar disorder connection, and suggests GAD may also be differentially associated with BPD. Further research is needed to clarify the etiologic basis of anxiety disorder/BPD comorbidity and to optimize treatment strategies for patients with these co-occurring disorders.     

Factors differentiating personality-disordered individuals with and without a history of unipolar mood disorder

The relationship between mood disorders and personality disorders has been of longstanding interest to clinicians. Despite theoretical reasons to do so, virtually no studies have examined factors that discriminate personality-disordered subjects with a history of mood disorder (PD/HMD) from personality-disordered subjects without a history of mood disorder (PD). This study examined demographic variables, patterns of comorbidity, measures of life functioning, personality traits, and early life experiences differentiating PD/HMD (n = 83) from PD (n = 214). Diagnoses were assigned using structured clinical interviews and a best-estimate procedure. The results suggest that subjects with borderline personality disorder are more likely to have a life history of mood disorder than are subjects with other personality disorders. In addition, PD/HMDs are more likely to receive a diagnosis of anxiety disorder or alcoholism, to have lower Global Assessment of Functioning (GAF) scores, and to have sought treatment than PDs. On self-report measures of personality, PD/HMDs endorse higher levels of trait anxiety and affective lability (e.g., Harm Avoidance, Neuroticism) than do PDs. PD/HMDs are also more likely to report childhood physical and emotional abuse than are PDs, and to describe their parents as using affectionless control. No differences were found between Axis II clusters as a function of mood disorder history. The discussion suggests a potential model in which early environmental stress interacts with constitutional vulnerabilities to put individuals at an increased risk for both mood and anxiety disorders as well as personality disorders.     

Anxiety disorders and tic severity in juveniles with Tourette's disorder

OBJECTIVE: It was hypothesized that comorbidity with anxiety disorders would predict tic severity in youths with Tourette's disorder (TD). METHOD: Subjects were 190 youths meeting DSM-III-R diagnostic criteria for TD who were consecutively referred to a pediatric psychopharmacology program between 1994 and 1997. Subjects were initially evaluated with a clinical interview and the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Epidemiologic version. Statistical analysis used t tests, chi 2 tests, and logistic regression analysis. RESULTS: One hundred thirty-four subjects were classified as mild/moderate and 56 as severe TD cases. No meaningful differences were found in socioeconomic status, gender distribution, or age at onset of TD between the 2 groups. The 2 groups could not be differentiated by the presence of comorbid mood or disruptive behavior disorders including attention-deficit hyperactivity disorder. Although obsessive-compulsive disorder (OCD) was overrepresented among the severe TD cases, the difference failed to reach statistical significance. Excluding social and simple phobias, all other anxiety disorders were more clearly overrepresented among subjects with severe TD; separation anxiety disorder most robustly predicted tic severity, irrespective of the presence of OCD or other anxiety disorders. CONCLUSION: Findings suggest that non-OCD anxiety disorders in general and separation anxiety disorder in particular may be significantly associated with tic severity in referred TD patients.     

Anxiety disorders in children and adolescents in the first six months after traumatic brain injury

The study's objective was to assess the nature, rate, predictive factors, and neuroimaging correlates of novel (new-onset) definite anxiety disorders and novel definite/subclinical anxiety disorders (in a broader group of children with at least subclinical anxiety disorders) after traumatic brain injury (TBI). Children with TBI from consecutive admissions to five trauma centers were enrolled and studied with psychiatric interviews soon after injury (baseline) and again 6 months post-injury. Novel definite anxiety disorder and novel definite/subclinical anxiety disorders were heterogeneous and occurred in 8.5% (N=12) and 17% (N=24) of participants, respectively, in the first 6 months after injury. Novel definite anxiety disorder was significantly associated with younger age at injury and tended to be associated with novel depressive disorder, as well as lesions of the superior frontal gyrus. Novel definite/subclinical anxiety disorder was significantly associated with concurrent psychiatric problems of personality change due to TBI and novel definite/subclinical depressive disorder, as well as with lesions of the superior frontal gyrus and a trend-association with frontal lobe white-matter lesions. These findings suggest that anxiety after childhood TBI may be part of a broader problem of affective dysregulation related to damaged dorsal frontal lobe and frontal white-matter systems, with younger children being at greatest risk for developing novel anxiety disorder after TBI.     

Differences between smokers and nonsmokers with anxiety disorders

Epidemiological data suggest that early smoking increases the risk for emergence of certain anxiety disorders (e.g., panic disorder, generalized anxiety disorder (GAD)), and that presence of certain anxiety disorders (e.g., social anxiety) increases the risk for later development of nicotine dependence. Although some studies report a high prevalence of smoking among anxiety disorders, the extent to which smokers with anxiety disorders differ from their nonsmoking counterparts remains uncertain. Differences between smokers and nonsmokers with anxiety disorders (N=527) were examined with respect to multiple measures of theoretical and clinical interest. Compared to nonsmokers, smokers with anxiety disorders reported greater anxiety sensitivity, anxiety symptoms, agoraphobic avoidance, depressed mood, negative affect, stress and life interference; however, these differences were largely accounted for by panic disorder. No differences were found between smokers and nonsmokers regarding social anxiety, worry, obsessive-compulsive symptoms or positive affect. Differential patterns were observed when evaluating constructs within anxiety disorder diagnoses.     

Mental disorders among persons with diabetes—Results from the World Mental Health Surveys

Objective

To estimate 12-month prevalence rate of mood, anxiety, and alcohol-use disorders among community samples of diabetic persons. We assess whether associations of specific mental disorders with diabetes are consistent across diverse countries after controlling for age and gender.

Research design and methods

Eighteen surveys of household-residing adults were conducted in two phases across 17 countries in Europe, the Americas, the Middle East, Africa, Asia, and the South Pacific (Part 1, N=85,088). Mental disorders, identified by the World Mental Health-Composite International Diagnostic Interview, included anxiety disorders (generalized anxiety disorder, panic disorder/agoraphobia, posttraumatic stress disorder, and social phobia), mood disorders (dysthymia and major depressive disorder), and alcohol abuse/dependence. Diabetes was ascertained by self-report (Part 2, N=42,697). Association was assessed by age-gender adjusted odds ratios.

Results

Risk of mood and anxiety disorders was slightly higher among persons with diabetes relative to those without: odds ratio of 1.38 for depression (95% CI=1.15-1.66) and 1.20 for anxiety disorders, (95 % CI=1.01-1.42), after adjusting for age and gender. Odds ratio estimates across countries did not differ more than chance expectation. Alcohol-use disorders were uncommon among persons with diabetes in most countries, and not associated with diabetes in pooled survey data.

Conclusions

Population sample surveys revealed mood and anxiety disorders occurred with somewhat greater frequency among persons with diabetes than those without diabetes. Prevalence of major depression among persons with diabetes was lower in the general population than suggested by prior studies of clinical samples. Strength of association did not differ significantly across disorders or countries.     

Comorbid anxiety in phenotypes of pediatric bipolar disorder

OBJECTIVE: There has been limited research on anxiety in pediatric bipolar disorder (BPD). Adult BPD studies suggest comorbid anxiety disorders are common and impact treatment outcome. We explored the association of comorbid anxiety with two phenotypes of pediatric BPD. METHODS: We studied two groups of children. The first group (BPD; N = 31) represents the "narrow phenotype" of pediatric BPD, meeting stringent DSM-IV criteria for mania, including duration and elevated/expansive mood. The second group (ED; N = 32) exhibited chronic, non-episodic irritability without elation or grandiosity ("broad phenotype"). RESULTS: Both samples demonstrate high prevalence of anxiety (BPD 77.4%; ED 46.9%). In the BPD sample, anxiety predates BPD onset, and those with comorbid anxiety have earlier age of onset of BPD than those without. Children with BPD plus anxiety have more hospitalizations than those without anxiety. ED subjects with and without comorbid anxiety did not differ with respect to onset of ED symptoms or number of hospitalizations. CONCLUSIONS: Narrow and broad phenotype BPD children have high rates of comorbid anxiety, although only in the narrow phenotype group is comorbid anxiety associated with greater functional impairment BPD plus comorbid anxiety may represent a particularly severe phenotype of pediatric BPD.     

Anxiety disorders associated with suicidal ideation and suicide attempts in the National Comorbidity Survey

This study examined the relationship between anxiety disorders and suicidal ideation or suicide attempts in a nationally representative sample (N = 5877; age, 15-54; response rate, 82.4%). A modified version of the Composite International Diagnostic Interview was used to make DSM-III-R mental disorder diagnoses. Two multivariate logistic regression analyses were performed with suicidal ideation (N = 754) and suicide attempts (N = 259) as dependent variables. In each regression, the independent variables entered were lifetime social phobia, panic disorder, agoraphobia, generalized anxiety disorder, simple phobia, and posttraumatic stress disorder (PTSD). Covariates in the analyses were sociodemographics, lifetime mood disorders, substance use disorders, nonaffective psychosis, antisocial personality disorder, and presence of three or more lifetime DSM-III-R diagnoses. PTSD was significantly associated with suicidal ideation (adjusted odds ratio = 2.79; p < 0.01) and suicide attempts (adjusted odds ratio = 2.67; p < 0.01). None of the other anxiety disorders were significantly associated with suicidal ideation or attempts. The robust association between PTSD and suicide attempts has important implications for psychiatric assessment of suicidal behavior. Future research is required to investigate the mechanisms underlying the relationship between PTSD and suicidal behavior.     

Hierarchical structures of affect and psychopathology and their implications for the classification of emotional disorders

The Diagnostic and Statistical Manual of Mental Disorders-IV groups disorders into diagnostic classes on the basis of the subjective criterion of "shared phenomenological features." The current mood and anxiety disorders reflect the logic of older models emphasizing the existence of discrete emotions and, consequently, are based on a fundamental distinction between depressed mood (central to the mood disorders) and anxious mood (a core feature of the anxiety disorders). This distinction, however, ignores subsequent work that has established the existence of a general negative affect dimension that (a) produces strong correlations between anxious and depressed mood and (b) is largely responsible for the substantial comorbidity between the mood and anxiety disorders. More generally, there are now sufficient data to eliminate the current rational system and replace it with an empirically based taxonomy that reflects the actual-not the assumed-similarities among disorders. The existing structural evidence establishes that the mood and anxiety disorders should be collapsed together into an overarching superclass of emotional disorders, which can be decomposed into three subclasses: the distress disorders (major depression, dysthymic disorder, generalized anxiety disorder, posttraumatic stress disorder), the fear disorders (panic disorder, agoraphobia, social phobia, specific phobia), and the bipolar disorders (bipolar I, bipolar II, cyclothymia). An empirically based system of this type will facilitate differential diagnosis and encourage the ultimate development of an etiologically based taxonomy.     

Prevalence of common mental disorders in Italy

OBJECTIVE: To present 1-month, 12-month and lifetime prevalence estimates of mood, anxiety and alcohol disorders in Italy; and the socio-demographic correlates and comorbidity patterns of these estimated disorders. METHOD: A representative random sample of non-institutionalised citizens of Italy aged 18 or older (N=4,712) was interviewed between January 2001 and July 2003, with a weighted response rate of 71.3%. DSM-IV disorders were assessed by lay interviewers using Version 3.0 of the Composite International Diagnostic Interview (CIDI). RESULTS: A total of 11% of respondents reported a lifetime history of any mood disorder, 10.3% any anxiety disorder and 1.3% any alcohol disorder. About 5% reported having an anxiety disorder in the past 12 months compared to 3.3% for any mood disorder and 0.2% for any alcohol disorder. Major depression and specific phobia were the most common mental disorders. Women were twice as likely as men to report a mood disorder and four times as likely as men to report an anxiety disorder, while men were twice as likely as women to report an alcohol disorder. High comorbidity of mood and anxiety disorders was observed. Prevalence estimates were generally lower than in parallel surveys carried out in other Western European countries. CONCLUSION: A high proportion of adults in Italy have a history of mood, anxiety or alcohol disorders. The lower than expected prevalence estimate of alcohol use disorder may be due to under-reporting or to low social harm from alcohol consumption.     

Correlates of ADHD among children in pediatric and psychiatric clinics

OBJECTIVE: Conventional wisdom among pediatricians has been that children with attention-deficit hyperactivity disorder (ADHD) who receive their diagnosis and are managed in the primary care setting have fewer comorbid psychiatric disorders and milder impairments than those seen in psychiatric clinics. The authors sought to determine whether comorbidity and clinical correlates of ADHD differ among children in these two settings. METHODS: A case-control study design was used. Participants were 522 children and adolescents of both sexes, six to 18 years of age, with (N=280) and without (N=242) ADHD. Participants were drawn from pediatric and psychiatric clinics in a tertiary care hospital and a health maintenance organization in a large metropolitan area. Assessments were conducted with standardized measures of psychiatric, cognitive, social, academic, and family function. RESULTS: The number, type, clusters, and age at onset of ADHD symptoms were nearly identical for youths at pediatric and psychiatric ascertainment sources. Regardless of source, participants with ADHD were significantly more likely than controls to have a higher prevalence of mood disorders, other disruptive behavior, anxiety disorders, and substance use disorders. Significant impairments of intellectual, academic, interpersonal, and family functioning did not differ between ascertainment sources. CONCLUSIONS: Children with ADHD from both psychiatric and pediatric practices have prototypical symptoms of the disorder; high levels of comorbidity with mood, anxiety, and disruptive behavior disorders; and impairments in cognitive, interpersonal, and academic function that do not differ by ascertainment source. These findings suggest that children cared for in pediatric practice have similar levels of comorbidity and dysfunction as psychiatrically referred youth.     

Attentional bias to threat in children at-risk for emotional disorders: role of gender and type of maternal emotional disorder

Previous studies suggested that threat biases underlie familial risk for emotional disorders in children. However, major questions remain concerning the moderating role of the offspring gender and the type of parental emotional disorder on this association. This study addresses these questions in a large sample of boys and girls. Participants were 6–12 years old (at screening) typically developing children participating in the High Risk Cohort Study for Psychiatric Disorders (n = 1280; 606 girls, 674 boys). Children were stratified according to maternal emotional disorder (none; mood disorder; anxiety disorder; comorbid anxiety/mood disorder) and gender. Attention biases were assessed using a dot-probe paradigm with threat, happy and neutral faces. A significant gender-by-parental emotional disorder interaction predicted threat bias, independent of anxiety and depression symptoms in children. Daughters of mothers with an emotional disorder showed increased attention to threat compared with daughters of disorder-free mothers, irrespective of the type of maternal emotion disorder. In contrast, attention bias to threat in boys only occurred in mothers with a non-comorbid mood disorder. No group differences were found for biases for happy-face cues. Gender and type of maternal emotional disorder predict attention bias in disorder-free children. This highlights the need for longitudinal research to clarify whether this pattern of threat-attention bias in children relates to the risk of developing anxiety and mood disorders later in life.
