An exploration of concomitant psychiatric disorders in children with autism spectrum disorder

ObjectiveWe explored patterns of concomitant psychiatric disorders in a large sample of treatment-seeking children and adolescents with autism spectrum disorder (ASD).MethodsParticipants were 658 children with ASD (age 3–17 years; mean = 7.2 years) in one of six federally-funded multisite randomized clinical trials (RCT) between 1999 and 2014. All children were referred for hyperactivity or irritability. Study designs varied, but all used the Child and Adolescent Symptom Inventory or Early Childhood Inventory to assess Attention Deficit Hyperactivity Disorder (ADHD), Oppositional-Defiant Disorder (ODD), Conduct Disorder (CD), Anxiety Disorders, and Mood Disorders. In addition, several measures in common were used to assess demographic and clinical characteristics.ResultsOf the 658 children, 73% were Caucasian and 59% had an IQ >70. The rates of concomitant disorders across studies were: ADHD 81%, ODD 46%, CD 12%, any anxiety disorder 42%, and any mood disorder 8%. Two or more psychiatric disorders were identified in 66% of the sample. Of those who met criteria for ADHD, 50% also met criteria for ODD and 46% for any anxiety disorder. Associations between types of concomitant disorders and a number of demographic and clinical characteristics are presented.ConclusionIn this well-characterized sample of treatment-seeking children with ASD, rates of concomitant psychiatric disorders were high and the presence of two or more co-occurring disorders was common. Findings highlight the importance of improving diagnostic practice in ASD and understanding possible mechanisms of comorbidity.     

Convergent and divergent validity of the schedule for affective disorders and schizophrenia for school-age children – present and lifetime version diagnoses in a sample of children and adolescents with obsessive–compulsive disorder

The presence of comorbid conditions associated with paediatric obsessive–compulsive disorder (OCD) is reported to range from 50 to 80% and to have an impact on treatment outcome. Accurate identification of comorbid psychiatric disorders is necessary in order to provide personalised care. Reliable and valid diagnostic interviews are essential in the process of establishing the correct diagnoses. The objective of this study was to evaluate the convergent and divergent validity of four diagnose categories generated by the Schedule for Affective Disorders and Schizophrenia for School-Age Children – Present and Lifetime Version (K-SADS-PL). The diagnose categories were: anxiety, depression, attention deficit hyperactivity disorder (ADHD), and oppositional defiant disorder (ODD). The K-SADS-PL was applied in a clinical sample of youth aged 7–17 years (N?=?269), who were participants in the Nordic long-term OCD-treatment study (NordLOTS). Youth and parents completed measures to evaluate symptoms of anxiety, depression, ADHD, and ODD. Convergent and divergent validity of K-SADS-PL anxiety diagnosis was supported based on both anxiety self- and parent-reports. Similarly, support was found for convergent and divergent validity of ADHD and ODD diagnoses. For depressive disorder, support for convergent validity was found based on the depression self-report. Support for divergent validity of depression was found based on both the depression self- and parent-reports. Results of the present study suggest that the K-SADS-PL generates valid diagnoses of comorbid anxiety disorders, depression disorders, ODD, and ADHD in children and adolescents with OCD.     

ODD and ADHD symptoms in Ukrainian children: external validators and comorbidity

OBJECTIVE: To examine potential external validators for oppositional defiant disorder (ODD) and attention-deficient/hyperactive disorder (ADHD) symptoms in a Ukrainian community-based sample of 600 children age 10 to 12 years old and evaluate the nature of co-occurring ODD and ADHD symptoms using mother- and teacher-defined groups. METHOD: In 1997, parents, children, and teachers participated in extensive clinical assessments using standard Western measures. Four areas of functioning were assessed: child mental health, parent-child interactions, parental well-being, and school/cognitive performance. RESULTS: Mother-defined ODD versus ADHD symptom groups were differentiated by a history of overactivity and tantrums, behavior in school, and maternal anxiety and hostility. Teacher-defined groups were differentiated by conduct problems, internalizing symptoms, mother-child interactions, and paternal alcohol use. The effects of co-occurring ODD and ADHD symptoms were greater than would be expected based on their separate effects for conduct problems, internalizing symptoms, social problems, academic performance, parent-child relations, and marital discord. CONCLUSIONS: Children with ODD versus ADHD symptoms were not significantly different from each other for the majority of variables examined, and group differences were dependent on the rater used to define symptom groups.     

Treatment for Co-Occurring Attention Deficit/Hyperactivity Disorder and Autism Spectrum Disorder

Interest in the co-occurrence of attention deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) has grown in the last decade. Research on clinical populations supports the frequent co-occurrence of ADHD traits (e.g., hyperactivity) in individuals with ASD and ASD traits (e.g., social communication deficits) in individuals with ADHD. Similar trends in co-occurring traits have been observed in population-based samples, as well as family and genetic studies of affected individuals. Despite increased interest in co-occurring ADHD and ASD, relatively little research has been devoted to treatment considerations. The vast majority of intervention research has examined pharmacological treatment using traditional ADHD medications. Relatively few psychosocial interventions have directly addressed co-occurring symptoms. Treatment development will benefit from enhanced understanding of the phenomenon of co-occurring ADHD and ASD. Key topics for future research include examining developmental trajectories of co-occurring disorders, comorbid psychiatric conditions, deficits in social skills, and the nature of executive functioning impairment in individuals with co-occurring ADHD and ASD. In the current review, research in these areas is reviewed along with recommendation for future study. Given that clinicians are routinely observing and treating individuals with co-occurring symptoms, further research will yield needed information to inform intervention development and maximize benefits for affected individuals.     

Anxiety and depression in adolescents with ADHD and autism spectrum disorders; correlation between parent- and self-reports and with attention and adaptive functioning

Background: Adolescents with attention-deficit/hyperactive disorder (ADHD) or autism spectrum disorder (ASD) are at high risk of anxiety and depression. This is important to identify in the clinical assessment to understand its impact.

Aims: The aim of this study is to investigate the correlation between parent- and self-reports of anxiety and depression in adolescents with ADHD or ASD, as well as the correlation with adaptive functioning and performance on an attention test.

Method: A total of 65 adolescents with an ADHD diagnosis (n?=?24) or an ASD diagnosis (n?=?41) filled out Beck Youth Inventories of Emotional and Social Impairment (BYI) to assess depression and anxiety and completed a Continuous Performance Test (QbTest) measuring ADHD symptoms. Parents of the participants completed the internalizing domain in the Five to Fifteen questionnaire (FTF), measuring symptoms of anxiety and depression, and the Vineland Adaptive Behavior Scales (VABS) about the adolescent’s adaptive functioning.

Results: Approximately a third of the study group self-reported substantial internalizing mental symptoms not always recognized by parents, and not always obvious in adaptive function or performance at ADHD test. Correlations between BYI and FTF were low. The BYI depression inventory correlated negatively with VABS and positively with activity level in a subgroup medicated for ADHD. There was a stronger correlation between girls BYI and FTF results as compared with boys.

Conclusions: The results highlight the need for identification of anxiety and depression, using both self- and parent report. Present anxiety and depression symptoms do not seem to affect the clinical assessment of ASD and ADHD.     

Oppositional Defiant Disorder as a Clinical Phenotype in Children with Autism Spectrum Disorder

To examine the validity of oppositional defiant disorder (ODD) as a clinical phenotype distinct from attention-deficit hyperactivity disorder (ADHD), parents and teachers completed a DSM-IV-referenced rating scale and a background questionnaire for 608 children (ages 3-12 years) with autism spectrum disorder (ASD). The ASD sample was separated into four groups: ODD, ADHD, ODD + ADHD, and neither (NONE). Comparison samples were non-ASD clinic (n = 326) and community (n > 800) controls. In the ASD sample, all three ODD/ADHD groups were clearly differentiated from the NONE group, and the ODD + ADHD group had the most severe co-occurring symptoms, medication use, and environmental disadvantage. There were few differences between ASD + ODD and ASD + ADHD groups. Findings for ASD and control samples were similar, supporting overlapping mechanisms in the pathogenesis of ODD.     

Co-occurring psychiatric disorders in children and adolescents with Tourette syndrome

More than half of all children and adolescents with Tourette syndrome show evidence of psychiatric comorbidity, exhibiting symptoms of attention-deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder, and other anxiety and mood disorders. Although the prevalence of co-occurring conditions varies depending on the clinical setting, it is crucial for clinicians to be familiar with these disorders because they are often more impairing than tics and can influence the initial treatment choice. Left untreated, these conditions can negatively affect important developmental outcomes, such as academic and social functioning. We review the most common co-occurring disorders, the relationship of these co-occurring disorders to Tourette syndrome, and treatment recommendations for co-occurring conditions when tic symptoms are present.     

Increased adrenal androgen functioning in children with oppositional defiant disorder: a comparison with psychiatric and normal controls

OBJECTIVE: To examine the relationship between adrenal androgens and aggression in children with oppositional and antisocial behavior and to compare their levels with those of psychiatric and normal controls. METHOD: Dehydroepiandrosterone sulfate (DHEAS) was measured in 24 children with oppositional defiant disorder (ODD), 42 psychiatric controls (including 20 children with attention-deficit/hyperactivity disorder [ADHD]), and 30 normal controls. The children's parents filled out the Child Behavior Checklist (CBCL). RESULTS: Children with ODD had higher DHEAS levels than either the psychiatric control or normal control groups; DHEAS levels of the latter groups did not differ. Moreover, it was possible to classify children as having either ODD or ADHD on the basis of their DHEAS levels, whereas this was not the case on the basis of the CBCL data. CONCLUSIONS: The results indicate that adrenal androgen functioning is specifically elevated in children with ODD. It is speculated that the mechanism could be a shift in balance of ACTH-beta-endorphin functioning in the hypothalamic-pituitary-adrenal axis due to early stress or genetic factors.     

Oppositional defiant disorder with onset in preschool years: longitudinal stability and pathways to other disorders.

OBJECTIVE: To examine the stability and change in oppositional defiant disorder (ODD) with onset among preschool children in a pediatric sample. METHOD: A total of 510 children aged 2-5 years were enrolled initially in 1989-1990 (mean age 3.42 years); 280 participated in five waves of data collection over a period of 48 to 72 months (mean wave 5 age, 8.35 years). Test batteries varied by age, but they included the Child Behavior Checklist, developmental evaluation, Rochester Adaptive Behavior Inventory, and a play session (before age 7 years) and a structured interview (Diagnostic Interview for Children and Adolescents, parent and child versions) at ages 7+ years. Consensus diagnoses were assigned by using best-estimate procedures. RESULTS: Wave 1 single-diagnosis ODD showed a significant relationship with both single-diagnosis ODD and single-diagnosis attention-deficit hyperactivity disorder (ADHD) at subsequent waves, but not with single-diagnosis anxiety or mood disorders. Single-diagnosis ODD at wave 1 was associated with later comorbidity of ODD/ADHD, ODD/anxiety, and ODD/mood disorders. Stability across waves 2 through 5 was moderate to high for comorbid ODD/anxiety and ODD/ADHD; low to moderate stability for single-diagnosis ODD and single-diagnosis mood disorder; and low for mood disorder, single-diagnosis ADHD, and single-diagnosis anxiety disorder. CONCLUSIONS: Preschool children with ODD are likely to continue to exhibit disorder, with increasing comorbidity with ADHD, anxiety, or mood disorders.     

Attention-deficit/hyperactivity disorder and comorbid oppositional defiant disorder or conduct disorder

Comorbid oppositional defiant disorder (ODD) and conduct disorder (CD) are common in clinically referred children and adolescents with attention-deficit/hyperactivity disorder (ADHD). Early recognition and treatment of co-occurring ADHD and ODD and/or CD is important because comorbidity influences symptom severity, prognosis, and treatment. Research on treatment supports the importance of behavior therapies for ODD and multimodal psychosocial interventions delivered simultaneously and intensively for CD with adjunctive medication for ADHD symptoms. Clinical trials are beginning to show that stimulants and atomoxetine are effective for ADHD and ODD symptoms when the disorders occur together. It is presently unclear if ODD in the absence of ADHD responds to pharmacotherapy. More research is needed examining the effects of commonly prescribed ADHD medications on CD symptoms. Research suggests a high prevalence of lifetime comorbidity with ODD in clinically referred patients with ADHD.     

Application of the Repetitive Behavior Scale-Revised – Italian version – in preschoolers with autism spectrum disorder

Restricted repetitive and stereotyped patterns of behavior, interests, and activities (RRB) are mandatory features for a diagnosis of Autism Spectrum Disorder (ASD) according to the Diagnostic and Statistical Manual of mental disorders-fifth edition (DSM-5). Despite the strong diagnostic role of RRB, their expressiveness and their relationship with other clinical/demographic features in ASD is not fully elucidated.The Italian version of the Repetitive Behavior Scale-Revised (RBS-R) was applied to a relatively large sample of preschool-aged children with ASD who underwent a comprehensive clinical assessment. The relationship between RRB and sex, age, non-verbal IQ, autism severity, as well as the diagnostic accuracy of the RBS-R were explored.Stereotyped and Ritualistic/Sameness behaviors were the most common RRB in preschoolers with ASD, without widespread differences between males and females. No significant correlations between RRB and chronological age, or non-verbal IQ were detected. The expressiveness of ritualistic/sameness behaviors positively correlated with autism severity, assessed through the Calibrated Severity Score (CSS) derived from the Autism Diagnostic Observation Schedule (ADOS). Receiver Operator Characteristic (ROC) analysis showed high diagnostic accuracy using the Global Rating Score, which represents the judgment of the parents of as the RRB affect the child's life. However, while the Global Rating Score performed well, the remaining subscales did not.This investigation extends the limited research on early pattern and associated features of RRB in young children with ASD. The use of the RBS-R may increase the knowledge of the RRB complexity and variability and in turn improve the diagnostic and therapeutic procedures within the autistic spectrum.     

Age-related differences in the prevalence and correlates of anxiety in youth with autism spectrum disorders

Age-related differences in the prevalence and correlates of anxiety were cross-sectionally examined in 1316 children and adolescents with autism spectrum disorder (ASD) who presented for initial evaluation at 14 outpatient autism centers around the country and in Canada. The prevalence of clinical and subclinical anxiety as well as the correlates of anxiety were examined in three age groups of children: preschool, school age and adolescents. Findings showed that the prevalence of anxiety in each age group exceeded the prevalence of anxiety in the general population. Adolescents and school age children had the highest prevalence of clinical (40%) and subclinical anxiety (26%), respectively. Higher IQ and less ASD severity were each weakly correlated with more anxiety in preschool and school age children. Affective symptoms were strongly associated with anxiety in each age group. Age specific psychiatric comorbidities were also present. Anxiety was associated with attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) symptoms in the preschool group, ODD and somatic symptoms in the school age children, and ADHD symptoms in adolescents. These data underscore the need for prevention and treatment of anxiety as well as research examining the characteristics of anxiety in children with ASD using a developmental framework.     

Attention-deficit/Hyperactivity Disorder in the Context of Autism Spectrum Disorders

Autism spectrum disorders (ASD) are frequently marked by symptoms consistent with attention-deficit/hyperactivity disorder (ADHD), namely inattention, hyperactivity, and impulsivity. Recent work has established that about half of the ASD population also meets diagnostic criteria for ADHD, although the comorbid diagnoses are precluded by the DSM-IV-TR. Individuals with co-occurring ASD and ADHD symptoms are more severely impaired, with significant deficits seen in social processing, adaptive functioning, and executive control. Children with ASD and ADHD symptoms are also prone to motor problems, which lead to especially poor outcomes. Recent work has also demonstrated high rates of ASD symptoms in a subset of children with ADHD. Medication studies have demonstrated the efficacy of methylphenidate, atomoxetine, and guanfacine, among others, in treating ADHD symptoms co-occurring with ASD. However, these effects were not as great as those seen when treating primary ADHD, and they are less well-tolerated in the ASD population.     

Predictors of Psychiatric Symptoms in Children with an Autism Spectrum Disorder

This study examined mental health risk/protective factors for DSM-IV psychiatric symptoms in children with an autism spectrum disorder (ASD) and their contribution to functioning separate from ASD symptom severity. Mothers/teachers completed measures of risk/protection and social, adaptive, and school functioning in 6- to 12-year-olds with a diagnosed ASD (N = 238). Bivariate correlations and simultaneous regression analyses indicated a unique pattern of predictors for attention-deficit/hyperactivity disorder, aggression, anxiety, and depression symptoms. Moreover, psychiatric symptoms differentially predicted social and school performance. Findings indicate that co-occurring psychiatric symptoms and their associated mental health risk/protective factors may have important clinical implications and generally support a biopsychosocial model of psychopathology in children with an ASD that appears to share many similarities with models for nonASD children.     

Comorbid psychiatric disorders in Arab children with Autism spectrum disorders

The objective of our study is to estimate the prevalence of comorbid psychiatric disorders in a sample of children with autism spectrum disorders (ASD) recruited from three Arab countries. We also examine the relationship between comorbidity and children's cognitive functioning and gender. Children who received a diagnosis of ASD (n = 60) from a child psychiatric outpatient clinic in Mansoura (Egypt), Al-Ahsa (Saudi Arabia) and Amman (Jordan) were included in this study. Comorbid diagnoses were established with a clinical interview and a semi-structured clinical interview for children and adolescents (SCICA). In addition, for all patients the cognitive evaluation was measured given the range in age and level of ability. Sixty-three percent of the children were diagnosed with at least one comorbid disorder. The most commonly reported comorbid disorders were anxiety disorders (58.3%), ADHD (31.6%), conduct disorders (23.3%), and major depressive disorder (13.3%). Out of the total sample, Obsessive compulsive disorder was the most prevalent anxiety disorder (55%). Elimination disorders were also diagnosed in 40% of patients. These findings emphasize a wide variety of psychiatric comorbidity afflicting youth with ASD and may be important targets for intervention.     

Children of currently depressed mothers: a STAR*D ancillary study

OBJECTIVE: To assess the current and lifetime prevalence of psychiatric disorders among children of currently depressed mothers and to assess the association of clinical features of maternal depression (i.e., severity, chronicity, and clinical features) with child psychopathology. Mothers were participants in the STAR*D (Sequenced Treatment Alternatives to Relieve Depression) multisite trial, designed to compare effectiveness and acceptability of different treatment options for outpatients with non-psychotic major depressive disorder (MDD). METHOD: Treatment-seeking mothers with a current DSM-IV diagnosis of MDD and with at least 1 child 7 to 17 years old were assessed during a major depressive episode (MDE). For each mother, 1 child was assessed (if a mother had more than 1 child, 1 was randomly selected). Maternal features assessed for this study were history of MDEs, severity of current MDE, comorbid conditions, depressive symptom features, and social functioning. Children were assessed for selected psychiatric diagnoses (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version [K-SADS-PL]), psychopathologic symptoms and social functioning (Child Behavior Checklist), and global functioning (Children's Global Assessment Scale). Data were gathered from December 2001 to April 2004. RESULTS: A large proportion (72%) of mothers were severely depressed (17-item Hamilton Rating Scale for Depression score >/= 22). About a third (34%) of children had a current psychiatric disorder, including disruptive behavior (22%), anxiety (16%), and depressive (10%) disorders. Nearly half (45%) had a lifetime psychiatric disorder, including disruptive behavior (29%), anxiety (20%), and depressive (19%) disorders. Atypical depressive features in the mother were associated with a 3-fold increase in the odds of having a child with depressive (OR = 3.3 [95% CI = 1.2 to 9.5]; p = .02) or anxiety (OR = 2.6 [95% CI = 1.1 to 6.9]; p = .03) disorders. A history of maternal suicide attempts and the presence of comorbid panic disorder with agoraphobia were associated with a 3-fold increase and an 8-fold increase in the odds of depressive disorders in the offspring, respectively. The final model showed significant associations (p 相似文献   

Autistic spectrum disorder,attention deficit hyperactivity disorder,and psychiatric comorbidities: A nationwide study

Attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are both frequently comorbid with other psychiatric disorders, but the comorbid effect of ASD and ADHD relative to the comorbid risk of other psychiatric disorders is still unknown. Using the Taiwan National Health Insurance Research Database, 725 patients with ASD-alone, 5694 with ADHD-alone, 466 with ASD + ADHD, and 27,540 (1:4) age-/gender-matched controls were enrolled in our study. The risk of psychiatric comorbidities was investigated. The ADHD + ASD group had the greatest risk of developing schizophrenia (hazard ratio [HR]: 95.89; HR: 13.73; HR: 174.61), bipolar disorder (HR: 74.93; HR: 19.42; HR: 36.71), depressive disorder (HR: 17.66; HR: 12.29; HR: 9.05), anxiety disorder (HR: 49.49; HR: 50.92; HR: 14.12), disruptive behavior disorder (HR: 113.89; HR: 93.87; HR: 26.50), and tic disorder (HR: 8.95; HR: 7.46; HR: 4.87) compared to the ADHD-alone, ASD-alone, and control groups. Patients with ADHD + ASD were associated with the greatest risk of having comorbid bipolar disorder, depressive disorder, anxiety disorder, disruptive behavior disorder, and tic disorder. The diagnoses of ASD and ADHD preceded the diagnoses of other psychiatric comorbidities. A comprehensive interview scrutinizing the psychiatric comorbidities would be suggested when encountering and following patients with both ASD and ADHD in clinical practice.     

Proximal psychiatric risk factors for suicidality in youth: the Great Smoky Mountains Study

CONTEXT: Psychiatric disorder is a major risk factor for suicidality but has poor positive predictive value. OBJECTIVES: To characterize proximal risks for suicidality associated with anxiety, depressive, disruptive behavior, and substance use disorders, and to test whether there are critical combinations of disorders that discriminate at-risk youth independent of severity of psychopathology. DESIGN: The Great Smoky Mountains Study, a representative sample of children and adolescents aged 9 to 16 years from the southeastern United States. Subjects and their parents were interviewed on multiple occasions from 1993 to 2000 about the subjects' recent psychiatric and suicidal history. SETTING: An epidemiological sample of youth. PARTICIPANTS: The sample included 1420 individual subjects with 6676 records across 8 waves of data collection. MAIN OUTCOME MEASURES: Wanting to die, suicidal ideation, suicide plans, or suicide attempt during the past 3 months. RESULTS: Eleven broad psychiatric profiles discriminated suicidal youth. Risk was greatest in association with current depression plus anxiety (specifically GAD [generalized anxiety disorder]) (odds ratio, 468.53) or depression plus a disruptive disorder (primarily ODD [oppositional-defiant disorder]) (odds ratio, 222.94). Unless comorbid, anxiety and substance use disorders were not proximally associated with suicidality. The severity of symptom-related impairment and, in some cases, total symptom load explained risk associated with all psychiatric profiles except depression plus anxiety, specifically GAD (adjusted odds ratio, 50.16). Severity of impairment and poverty defined by federal guidelines for families were both independent risk factors, irrespective of psychiatric profile. Suicidal youth without diagnosable disorders had subthreshold (mostly disruptive) disorders, disabling relationship difficulties, or psychiatric symptoms without associated impairment. CONCLUSIONS: Severity of symptom-related impairment and total symptom load explained most of the risk for suicidality associated with current psychiatric disorders. Only depression plus GAD discriminated at-risk youth independent of severity of psychopathology.     

Is oppositional defiant disorder a meaningful diagnosis in adults? Results from a large sample of adults with ADHD

We examined the prevalence and clinical characteristics of oppositional defiant disorder (ODD) in a sample of clinically referred adults with attention deficit hyperactivity disorder (ADHD). Subjects were consecutively referred adults with a DSM-III R/IV diagnosis of ADHD with or without ODD. Nearly half of subjects (43%) had a history of ODD. Subjects with a childhood history of ODD had increased risk for bipolar disorder, multiple anxiety disorders, and substance use disorders relative to the ADHD subjects without ODD. We concluded, as in children with ODD, adults with a childhood history of ODD have high rates of psychiatric comorbidity and more impaired psychosocial functioning than those without this condition. A better understanding of the course, phenomenology, and clinical significance of ODD in adults is needed to better understand therapeutic approaches for this disorder.     

Comorbid anxiety and depression in school-aged children with attention deficit hyperactivity disorder (ADHD) and selfreported symptoms of ADHD,anxiety, and depression among parents of school-aged children with and without ADHD

Background

Attention deficit hyperactivity disorder (ADHD) is a common psychiatric disorder in children that can extend into adulthood and that is often associated with a variety of comorbid psychiatric disorders.

Aim

Assess the comorbidity of ADHD with anxiety disorders and depressive disorders in school-aged children, and the relationship of the severity of ADHD, anxiety, and depressive symptoms in children who have ADHD with the severity of the corresponding symptoms in their parents.

Methods

A two-stage screening process identified children 7-10 years of age with and without ADHD treated at the Xin Hua Hospital in Shanghai. ADHD and other DSM-IV diagnoses were determined by a senior clinician using the Schedule for Affective Disorder and Schizophrenia for School-Aged Children (K-SADS-PL). One parent for each enrolled child completed three self-report scales: the ADHD Adult Self Report Scale (ASRS), the State-Trait Anxiety Inventory (STAI), and the Beck Depression Inventory (BDI). In total 135 children with ADHD and 65 control group children without ADHD were enrolled; parents for 94 of the children with ADHD and 63 of the children without ADHD completed the parental assessment scales.

Results

Among the 135 children with ADHD, 27% had a comorbid anxiety disorder, 18% had a comorbid depressive disorder, and another 15% had both comorbid anxiety and depressive disorders. Parents of children with ADHD self-reported more severe ADHD inattention symptoms than parents of children without ADHD and were more likely to meet criteria for adult ADHD. Mothers (but not fathers) of children with ADHD had significantly more severe trait anxiety and depressive symptoms than mothers of children without ADHD. Among children with ADHD, the severity of ADHD symptoms was not significantly correlated with the severity of ADHD symptoms in parents, but depressive symptoms and anxiety symptoms in the children were significantly correlated with the corresponding symptoms in the parents.

Conclusion

School-aged children with ADHD commonly suffer from comorbid anxiety and depressive disorders, and the severity of these symptoms parallels the level of anxiety and depressive symptoms in their parents. Self-reported symptoms of ADHD are significantly more common in parents of children with ADHD than in parents of children without ADHD. Longitudinal studies are needed to disentangle the genetic, biological, and social factors responsible for these complex inter-relationships.
