Gender and conduct problems predict peer functioning among children with attention-deficit/hyperactivity disorder

Triarchic traits as risk versus protective factors for ADHD symptomatology: A prospective longitudinal investigation

Attention-deficit/hyperactivity disorder (ADHD) symptoms are associated with myriad adverse outcomes, including interpersonal difficulties, but factors that moderate the developmental course and functional impact of ADHD over time are not well understood. The present study evaluated developmental contributions of the triarchic neurobehavioral traits (boldness, meanness, and disinhibition) to ADHD symptomatology and its subdimensions from adolescence to young adulthood. Participants were twins and triplets assessed at ages 14, 17, and 19 (initial N = 1,185, 51.2% female). Path analyses using negative binomial regression revealed that boldness at age 14 was associated with more ADHD symptoms cross-sectionally (especially hyperactivity/impulsivity), but fewer symptoms (especially inattention) at age 19 in the prospective analysis. Notably, inclusion of interpersonal problems at ages 14 and 17 as covariates reduced the latter effect to nonsignificant. Disinhibition concurrently and prospectively predicted higher levels of ADHD symptoms, including both subdimensions, and the prospective effects were partially mediated by greater social impairment at age 17. Meanness prospectively (but not concurrently) predicted higher levels of hyperactivity/impulsivity symptoms. Sex moderated certain associations of meanness and disinhibition with ADHD symptoms. These findings highlight how fundamental neurobehavioral traits shape both psychopathology and adaptive outcomes in the developmental course of ADHD.

The Influence of Cognitive Appraisals on the Association between Callous-Unemotional Traits and Conduct Problems during Middle Childhood

Existing research on callous-unemotional (CU) traits and conduct problems primarily focuses on the concurrent or unidirectional associations between these constructs (i.e., from CU traits to CP), with less attention given to their dynamic interplay during middle childhood. It is possible that socialization agents, such as peers, play a significant role in shaping the dynamic relation between CU traits and conduct problems early in development. Additionally, prior studies have shown that both CU traits and conduct problems are associated with poorer peer functioning. Considering the social information processing theory, which emphasizes the impact of cognitive processes on emotions and behavior in youth, this study evaluated the moderating role of cognitive appraisals (i.e., rumination, self-blame, and other-blame) in the context of peer conflict on the bidirectional association between callous-unemotional (CU) traits and conduct problems over the course of 1 academic year. The sample included 349 third- through fifth-grade students (51% boys; 53.2% Hispanic/Latinx) and their homeroom teachers (n = 30). At Time 1, children reported on their cognitive appraisals in response to peer conflict. Teachers provided reports of children's CU traits and conduct problems at Time 1 and Time 2. Results indicated that conduct problems and other-blame uniquely predicted increases in CU traits over time. Further, high levels of self-blame and rumination exacerbated the prospective link from CU traits to subsequent conduct problems. These findings highlight the importance of addressing cognitive processes in prevention approaches aimed at reducing the risk of conduct problems and CU traits among children.

Peer Problems and Prosocial Behavior Among Icelandic Children and Adolescents with ADHD and/or Autism: Gender and Age Differences

Children with neurodevelopmental disorders tend to have more social difficulties than typically developing children. The aim of the current study was to examine parent and teacher-reported effects of age and gender on social functioning in a large clinical sample of children and adolescents with ADHD, autism, or co-occurring ADHD and autism using a cross-sectional study design. This nationwide clinical sample included 2132 Icelandic children and adolescents (35% girls, 65% boys) aged 5-18 years referred for a neurodevelopmental diagnostic assessment (ADHD and/or autism) in Iceland. Social functioning was measured using the Prosocial behavior and Peer problem subscales on the Strengths and Difficulties Questionnaire (SDQ) completed by parents and teachers. Results revealed that autistic youth and youth with co-occurring ADHD and autism experienced more peer problems and showed less prosocial behavior than youth with ADHD only. According to parents and teachers, girls were found to experience more social difficulties compared to boys. Interaction for age and gender, although only significant for teacher reports, indicated that younger girls with neurodevelopmental disorders experience more peer problems and show less prosocial behavior than older girls. In contrast, boys with neurodevelopmental disorders experience similar issues at all ages. The results suggest different patterns of social difficulties for boys and girls with neurodevelopmental disorders. Future research should examine different developmental pathways of social challenges for boys and girls. Implications for developing and providing clinical interventions appropriate developmental stages are discussed.

How Self-Regulation and Executive Functions Deficits Affect Quality of Life of Children/Adolescents with Emotional Regulation Disorders

BACKGROUND

Deficits in self-regulation and executive functions (EFs) frequently characterize children/adolescents with emotional regulation disorders and restrict their daily function and quality of life (QOL). These deficits are mainly manifested by neuropsychological measures in laboratory settings. This study aimed to compare self-regulation and EFs by ecological measures to reflect the implications in daily life between children with emotional regulation disorders and healthy controls and examine the relations between self-regulation, EFs and QOL in the study group.

METHODS

the participants were 49 children aged 8-18: 25 children/adolescents with emotional regulation disorders and 24 healthy children. The parents completed a socio-demographic questionnaire, the Child Behavior Checklist (CBCL), the Behavior Rating Inventory of Executive Functions (BRIEF) and the Pediatric Quality of Life Inventory (Peds-QL).

RESULTS

The study group had greater self-regulation difficulties (internalization and externalization problems), executive dysfunctions (EFdys) (including metacognition difficulties) and a lower QOL. Their internalization and externalization problems correlated with reduced EFs and QOL. Internalization predicted the physical and emotional QOLs, while metacognition predicted social and school-related QOLs.

CONCLUSIONS

Deficits in self-regulation and EFs are prevalent in children/adolescents with emotional disorders and restrict their daily function and QOL. Therefore, they should be routinely evaluated by ecological instruments to reflect daily restrictions.

Social difficulties in adolescent attention deficit hyperactivity disorder: Social motivation, social anxiety and symptom severity as contributing factors

BACKGROUND

Many interventions have been developed to address the social difficulties commonly experienced by adolescents with attention-deficit/hyperactivity disorder (ADHD), yet they are largely ineffective.

OBJECTIVE

This study examined social impairment among adolescents with and without ADHD, determining whether gender, social anxiety, age, and ADHD symptom type (inattention and hyperactivity/impulsivity) and severity are associated with social impairment.

METHOD

Parents and primary caregivers of adolescents (aged 13-17) with (n = 76) and without ADHD (n = 36) completed the Strengths and Weaknesses of ADHD and Normal Behavior, Social Responsiveness Scale 2nd Edition, and Spence Children's Anxiety Scale.

RESULTS

Adolescents with ADHD scored significantly higher than TD adolescents across social impairment domains. ADHD symptoms were associated with severity of impairment in all domains excluding Social Motivation. Hyperactivity/impulsivity and social anxiety predicted social impairment, whereas gender did not.

CONCLUSION

Adolescents with ADHD are more likely to experience social impairment than TD adolescents, and interventions targeting symptom reduction and social anxiety may improve these social impairments.

Internalizing-Externalizing Comorbidity and Impaired Functioning in Children

BACKGROUND

The comorbidity of mental illnesses is common in child and adolescent psychiatry. Children with internalizing-externalizing comorbidity often experience worse health outcomes compared to children with a single diagnosis. Greater knowledge of functioning among children with internalizing-externalizing comorbidity can help improve mental health care.

OBJECTIVE

The objective of this exploratory study was to examine whether internalizing-externalizing comorbidity was associated with impaired functioning in children currently receiving mental health services.

METHODS

The data came from a cross-sectional clinical sample of 100 children aged 4-17 with mental illness and their parents recruited from an academic pediatric hospital. The current mental illnesses in children were measured using the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID), and the level of functioning was measured using the World Health Organization Disability Assessment Schedule (WHODAS) 2.0. Linear regression was used to estimate the association between internalizing-externalizing comorbidity and level of functioning, adjusting for demographic, psychosocial, and geographic covariates.

RESULTS

Internalizing-externalizing comorbidity in children was associated with worse functioning compared to children with strictly internalizing comorbidities, β = 0.32 (p = 0.041). Among covariates, parent's psychological distress, β = 0.01 (p = 0.004), and distance to the pediatric hospital, β = 0.38 (p = 0.049) were associated with worse functioning in children.

CONCLUSIONS

Health professionals should be mindful that children with internalizing-externalizing comorbidity may experience worsening functioning that is disruptive to daily activities and should use this information when making decisions about care. Given the exploratory nature of this study, additional research with larger and more diverse samples of children is warranted.

Primary School Children’s Self-Reports of Attention Deficit Hyperactivity Disorder-Related Symptoms and Their Associations With Subjective and Objective Measures of Attention Deficit Hyperactivity Disorder

Background

The diagnosis of Attention deficit hyperactivity disorder (ADHD) is primarily dependent on parents’ and teachers’ reports, while children’s own perspectives on their difficulties and strengths are often overlooked.

Goal

To further increase our insight into children’s ability to reliably report about their ADHD-related symptoms, the current study examined the associations between children’s self-reports, parents’ and teachers’ reports, and standardized continuous performance test (CPT) data. We also examined whether the addition of children’s perceptions of ADHD-symptoms to parents’ and teachers’ reports would be reflected by objective and standardized data.

Methods

The study included 190 children with ADHD, aged 7–10 years, who were referred to a pediatric neurologic clinic. A retrospective analysis was conducted using records of a clinical database. Obtained data included children’s self-reports of their attention level and ADHD-related symptoms, parent, and teacher forms of the Conners ADHD rating scales, Child Behavior Checklist (CBCL), Teacher’s Report Form (TRF), and CPT scores.

Results

Children’s self-evaluations of their functioning were globally associated with their teachers’ and parents’ evaluations, but not uniquely. Children’s self-reports of ADHD symptoms were not uniquely linked to a specific CPT impairment index, but to a general likelihood of having an impaired CPT. The CPT performance successfully distinguished between the group of children who defined themselves as inattentive and those who did not.

Conclusion

Primary school children with ADHD are able to identify their limitations and needs difficulties and that their perspectives should inform clinical practice and research. The clinical and ethical imperative of taking children’s perspectives into account during ADHD diagnosis and treatment is highlighted.

Test-Retest Reliability of the 25-item version of Wender Utah Rating Scale. Impact of Current ADHD Severity on Retrospectively Assessed Childhood Symptoms

Objective: To investigate test-retest reliability of the 25-item version of Wender Utah Rating Scale (WURS-25) and factors influencing retrospective reports of childhood behavior in adults with ADHD. Method: Eighty-five adults with ADHD and 189 controls completed the WURS-25 and the adult ADHD Self-Rating Scale (ASRS) at two time points (mean interval = 7 years) and provided information about dyslexia, somatic, and psychiatric disorders. Results: The correlation between WURS-25 scores at the two time points was strong, and reports from 60% of the adults with ADHD showed no change in severity level. Reports on the WURS-25 were positively associated with current ADHD symptoms at both time points and the presence of dyslexia and mood disorders, with the strongest association found among adults reporting the most severe WURS-25 score. Conclusion: Although our study showed an acceptable test-retest reliability of WURS-25, the substantial contribution from current ADHD symptoms to the WURS scores emphasizes the importance of collateral information from family members and others who knew the adult in childhood.

Identifying Neural Markers of Peer Dysfunction in Girls with ADHD

Very little research has prioritized girls with ADHD, despite accumulating evidence showing that girls with ADHD experience broader and more severe peer dysfunction relative to boys with ADHD. Attention to identifying the neural mechanisms underlying the peer difficulties of girls with ADHD is critical in order to develop targeted intervention strategies to improve peer functioning. New efforts to address the peer dysfunction of girls with ADHD are discussed.

Correlates of Loneliness in Children with Attention-Deficit/Hyperactivity Disorder: Comorbidities and Peer Problems

Children with attention-deficit/hyperactivity disorder (ADHD) are well-documented to experience social-emotional difficulties; however, little is known about their loneliness-an aspect of social-emotional functioning. Using a cross-sectional design, we examined how loneliness relates to comorbid internalizing disorders, externalizing disorders, and peer problems in a sample of 213 children with ADHD. Children (66 girls, M_age = 8.58, SD_age = 1.55) reported their loneliness. Comorbid internalizing and externalizing disorders were assessed via a multi-informant procedure. Proportion of classmates who accepted, rejected, and ignored the child, friendship quantity, and friendship quality were peer problem indicators. Results suggested that children with comorbid internalizing disorders, fewer friendships, or potentially more negative friendship quality, reported more loneliness. Gender appeared to moderate the association between peer rejection and loneliness, such that boys with peer rejection reported more loneliness than girls. Clinical implications include targeting loneliness as a social-emotional problem to assess and treat in children with ADHD.

Behavioral Treatment for the Social-Emotional Difficulties of Preadolescent and Adolescent Girls with ADHD

Girls with attention-deficit/hyperactivity disorder (ADHD) are at high risk for peer difficulties that often persist into adolescence and adulthood and portend risk for additional difficulties, such as depression, anxiety, and borderline personality disorder. However, very little research has examined interventions that address the widespread peer difficulties of girls with ADHD. This paper describes two open trials of behavior therapy aimed at addressing their social-emotional difficulties. The first trial includes 33 preadolescent girls (ages 7-11) with ADHD enrolled in an eight-week treatment and the second trial includes 22 adolescent girls (ages 12-16) with ADHD enrolled in a 12-week treatment. Measures of treatment feasibility and acceptability and measures of social functioning and psychopathology were collected in both trials. High levels of treatment feasibility and acceptability were reported in both the preadolescent and adolescent trial. In addition, improvements were reported in areas of social functioning and reductions in psychopathology, although the magnitude and specific areas of improvement differed somewhat in the preadolescent versus adolescent group. These preliminary findings provide a first step towards addressing the widespread social-emotional difficulties of girls with ADHD and offer insight into continuing efforts to address their treatment needs.

The affective temperament traits and pregnancy-related depression in mothers may constitute risk factors for their children with attention deficit and hyperactivity disorder

We investigated whether the affective temperaments of mothers and maternal depression before and during the index pregnancy are related to the development of Attention-Deficit Hyperactivity Disorder (ADHD) in their children. One hundred and twenty children were screened for the diagnosis of ADHD. After exclusion and inclusion criteria were applied for children and their mothers, we compared the mothers of children with (n = 63) and without ADHD (n = 60) in terms of affective temperament traits, depression before and during the index pregnancy, and some environmental risk factors. The rate of boys were significantly higher among children with ADHD compared to healthy controls. The mothers of children with ADHD had significantly lower education levels, more cigarette consumption during pregnancy, and more depression rates before the pregnancy than those of healthy children. Male gender (p = .002), Hamilton Depression Rating Scale (HDRS) (p = .002), cyclothymic (p = .022), irritable (p = .035) and anxious temperament scores (p = .016) significantly predicted the association between the mothers and their children with ADHD. Our findings might suggest that male child gender, the severity of depression at index pregnancy, higher cyclothymic, irritable, and anxious temperament scores in mothers may constitute as important risk factors for the development of ADHD in their children.Impact statementWhat is already known on this subject? Although the effects of maternal depression on ADHD were extensively investigated, the relationship between affective temperament traits of mothers and ADHD in their children has not been sufficiently examined. To investigate the roles of maternal affective temperament traits and pregnancy-related depression on offspring ADHD would help us to understand the etiopathogenic bases of ADHD.What do the results of this study add? Cyclothymic, irritable and anxious temperaments of mothers were significantly associated with the offspring ADHD after adjusting for the gender, maternal smoking, prepartum and antenatal depression.What are the implications of these findings for clinical practice and/or further research? These findings might demonstrate that some maternal affective temperaments and depression during pregnancy are suggestive of an inherited predisposition to ADHD in offsprings. Longitudinal studies are required to demonstrate the relationship between maternal affective temperament features and the development of affective illness in children with ADHD.

Meta-Analysis of Sex Differences in Social and Communication Function in Children With Autism Spectrum Disorder and Attention-Deficit/Hyperactivity Disorder

Background: Sex differences in the prevalence of neurodevelopmental disorders such as autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are well documented, but studies examining sex differences in social and communication function remain limited and inconclusive. Objectives: The objective of this study is to conduct a meta-analysis of sex differences in social-communication function in children with ASD or ADHD and typically developing controls. Methods: Using PRISMA, a search was performed on Medline and PSYCHINFO on English-language journals (2000-2017) examining sex differences in social and communication function in ASD and ADHD compared to controls. Inclusion criteria: 1) peer reviewed journal articles, 2) diagnosis of ASD or ADHD and controls, 3) age 6-18 years, 4) measures of social-communication function, and 5) means, standard deviations, and sample sizes reported in order to calculate standardized mean differences (SMD). Results: Eleven original/empirical studies met inclusion criteria for ASD and six for ADHD. No significant sex differences were found between ASD and controls in social (SMD = -0.43; p = 0.5; CI: -1.58-0.72), or communication function (SMD = 0.86; p = 0.5 CI; -1.57--3.30) and between ADHD and controls in social function (SMD = -0.68: p = 0.7, CI: -4.17-2.81). No studies evaluated sex differences in communication in ADHD. Significant heterogeneity was noted in all analyses. Type of measure may have partially accounted for some variability between studies. Conclusions: The meta-analysis did not detect sex differences in social and communication function in children with ASD and ADHD; however, significant heterogeneity was noted. Future larger studies, controlling for measure and with adequate numbers of female participants are required to further understand sex differences in these domains.

Sex Differences in Social Adaptive Function in Autism Spectrum Disorder and Attention-Deficit Hyperactivity Disorder

Background: Social-communication difficulties, a hallmark of ASD, autism spectrum disorder (ASD) are often observed in attention - deficit/ hyperactivity disorder (ADHD), although are not part of its diagnostic criteria. Despite sex differences in the prevalence of ASD and ADHD, research examining how sex differences manifest in social and communication functions in these disorders remains limited, and findings are mixed. This study investigated potential sex differences with age in social adaptive function across these disorders, relative to controls. Method: One hundred fifteen youth with ASD, 172 youth with ADHD, and 63 typically developing controls (age range 7-13 years, 75% males) were recruited from the Province of Ontario Neurodevelopmental Disorder (POND) Network. Social adaptive function was assessed using the Adaptive Behavior Assessment System-Second Edition (ABAS-II). The proportions of adaptive behaviors present in each skill area were analyzed as a binomial outcome using logistic regression, controlling for age, and testing for an age-by-sex interaction. In an exploratory analysis, we examined the impact of controlling for core symptom severity on the sex effect. Results: Significant sex-by-age interactions were seen within ASD in the communication (p = 0.005), leisure (p = 0.003), and social skill areas (p < 0.0001). In all three areas, lower scores (indicating poorer function) were found in females compared to males at older ages despite females performing better at younger ages. There were significant differences in the sex-by-age interactions in the social and leisure domains between those with ASD and typically developing controls, with typically developing females showing better scores at older, compared to younger, ages. There were also significant differences in the sex-by-age interactions between ASD and ADHD on the social and leisure domains, as females with ADHD consistently scored higher on social skills than males across all ages, unlike those with ASD. Sex differences across age in the social domains for ADHD were similar to those in the typically developing group. Conclusion: Sex differences in social and communication skill areas were observed between ASD and ADHD, and typically developing controls, with females with ASD performing worse than males at older ages, despite an earlier advantage. These findings reinforce the need to take a developmental approach to understanding sex differences which may have diagnostic, prognostic, and treatment implications.

Females With ADHD Report More Severe Symptoms Than Males on the Adult ADHD Self-Report Scale

OBJECTIVE

To investigate gender differences in self-reported ADHD symptoms in a group of adults with ADHD and a control group.

METHODS

A total of 682 adults with ADHD (49.9% females) and 882 controls (59.2% females) completed the Adult ADHD Self-Report Scale (ASRS), listing the 18 symptoms included in the diagnostic criteria of ADHD.

RESULTS

Within the ADHD group, females reported more severe symptoms of inattention and hyperactivity/impulsivity than males. This higher symptom report of females was not found in the control group, where the number of severe inattention symptoms rather was higher in males.

CONCLUSION

The results suggest that childhood symptoms of ADHD may have gone unnoticed in girls, emphasizing the need for longitudinal studies of ADHD symptoms across the life span.

ADHD and Gender: subjective experiences of children in Chile

Abstract Although research on ADHD has tended to ignore gender differentials, recent contributions produced mainly from epidemiology have revealed that this diagnostic category seems to be strongly related to gender. However, these contributions seem to limit their scope to the study of the symptoms as well as cognitive, affective and social functioning of children, leaving aside subjective aspects associated with the ADHD practices of diagnosis and treatment. Thus, this article aims to explore how the gender dimension crosses the subjective experience of children diagnosed with ADHD. Based on open interviews conducted with children between the ages of 7 and 13, we show general trends that articulate gender and characteristics associated with the ADHD diagnosis, while at the same time, with children’s experiences that dislocate such trends. The findings were grouped according to four emerging axes: (1) locations, (2) abilities, (3) approches, (4) interactions. Thus, we will show how the experience of boys and girls is multiple in relation to the diagnosis and it is not possible to be reduced to a gender binary perspective.

Social functioning in youth with attention-deficit/hyperactivity disorder and autism spectrum disorder: transdiagnostic commonalities and differences

Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD) are both neurodevelopmental disorders originating in childhood with high associated impairments and public health significance. There has been growing recognition of the frequent co-occurrence, and potential interrelatedness, between ADHD and ASD without intellectual disability. In fact, the most recent (5th) edition of the DSM is the first to allow ADHD and ASD to be diagnosed in the same individual. The study of transdiagnostic features in ADHD and ASD is important for understanding, and treating, these commonly co-occurring disorders. Social impairment is central to the description and prognosis of both disorders, and many youth with some combination of ADHD and ASD present to clinics for social skills training interventions. However, the aspects of social functioning that are impaired may have both shared and distinct features between the two disorders, relating to some overlapping and some diverse etiologies of social problems in ADHD compared to ASD. These findings have implications for interventions to address social problems in youth with these conditions. We conclude with a discussion about areas for future research and novel intervention targets in youth with ADHD, ASD, and their comorbidity.

Sex-specific trajectories of ADHD symptoms from adolescence to young adulthood

Reports of current ADHD symptoms in adults with a childhood diagnosis of ADHD are often discrepant: While one subgroup reports a particularly high level of current ADHD symptoms, another reports-in contrast-a very low level. The reasons for this difference remain unclear. Although sex might play a moderating role, it has not yet been examined in this regard. In an epidemiological cohort study from birth to young adulthood, childhood ADHD diagnoses were assessed at the ages of 4.5, 8, and 11 years based on parent ratings. Sex-specific development of ADHD symptoms was analyzed from the age of 15 to 25 years via self-reported ADHD symptoms in participants with (n = 47) and without childhood ADHD (n = 289) using a random coefficient regression model. The congruence between parent reports and adolescents' self-ratings was examined, and the role of childhood ADHD diagnosis, childhood OCC/CD, and childhood internalizing disorder as possible sex-specific predictors of self-reported ADHD symptoms at age 25 years was investigated. With regard to self-reported ADHD symptoms, females with a childhood ADHD diagnosis reported significantly more ADHD symptoms compared to females without childhood ADHD and males with and without ADHD throughout adolescence and young adulthood. In contrast, males with childhood ADHD did not differ from control males either at age 15 or at age 25 years. Only in females did a childhood diagnosis of an externalizing disorder (ADHD and CD/ODD) predict self-reported ADHD symptoms by age 25 years. Our findings suggest that self-reports of young adults with a childhood diagnosis of ADHD are influenced by sex. Specifically, females with childhood ADHD report increased levels of ADHD symptoms upon reaching adulthood. To correctly evaluate symptoms and impairment in this subgroup, other, more objective, sources of information may be advisable, such as neurophysiological measures.

Change in Maternal Stress for Families in Treatment for their Children with Oppositional Defiant Disorder

Our objective was to predict change in maternal stress over the course of a randomized clinical trial comparing the efficacy of two interventions for Oppositional Defiant Disorder (ODD): Parent Management Training and Collaborative & Proactive Solutions. In a secondary analysis of data collected from this randomized clinical trial, we examined whether children's self-reported positive relations with their parents impacted responsiveness to treatment, which in turn impacted maternal stress. One hundred thirty-four children and their parents (38.1% female, ages 7-14, M age = 9.51, SD = 1.77) were tracked across three time points: pre-treatment; one-week post-treatment; and six-month post-treatment. Hierarchical linear models tested change in children's reports of positive relations with parents, clinician reports of ODD severity, and maternal reports of parenting stress. Models then tested multilevel mediation from positive relations with parents, through ODD severity, onto maternal stress. Hypothesized indirect effects were supported such that children's reports of positive views toward parents uniquely predicted reductions in ODD severity over time, which in turn uniquely predicted reductions in maternal stress. Results highlight the promise of potential secondary benefits for parents following interventions for children with oppositional problems. Furthermore, results underscore the importance of the parent-child relationship as both a protective factor and as an additional target to complement interventions for child disruptive behaviors.

The impact of comorbid mental health symptoms and sex on sleep functioning in children with ADHD

Children with attention-deficit/hyperactivity disorder (ADHD) display more sleep problems than their peers, but it remains unclear whether comorbid mental health symptoms [i.e., anxiety, depression, oppositional-defiant disorder (ODD)] are uniquely related to sleep functioning. It is also largely unknown whether boys and girls with ADHD differ in their sleep functioning. This study (1) examined whether boys or girls with ADHD differ in their sleep functioning, (2) evaluated comorbid symptoms as uniquely related to sleep functioning domains, and (3) explored whether sex moderated associations between comorbid symptoms and sleep. Participants were 181 children (ages 7-13; 69% male; 82% White) diagnosed with ADHD. Parents completed measures assessing their child's ADHD symptoms, comorbid symptoms, and sleep functioning. Girls had poorer sleep functioning than boys across most sleep functioning domains. Sixty percent of children met cutoff criteria for having sleep problems, though rates differed significantly between girls (75%) and boys (53%). No differences in rates of sleep problems were found between ADHD subtypes/presentations or between younger and older children. In path models including ADHD and comorbid symptom dimensions, anxiety symptoms were uniquely associated with increased bedtime resistance and sleep anxiety, ADHD hyperactive-impulsive symptoms were associated with more night wakings and more parasomnia behaviors, and ODD and depressive symptoms were associated with shorter sleep duration. Depression was also uniquely associated with increased daytime sleepiness and overall sleep problems. Sex did not moderate associations between comorbid symptoms and sleep problems. This study provides important preliminary evidence that girls with ADHD experience more sleep problems than boys with ADHD. Findings also demonstrate that the associations between comorbid symptoms and sleep functioning in children with ADHD vary based on both the specific symptoms and sleep domains examined.

Correlates of bullying and its relationship with psychiatric disorders in Lebanese adolescents

Understanding the contextual determinants of bullying behavior is pivotal for effective interventions. This paper describes the prevalence of bullying, its socio-demographic correlates and factors influencing its relationship with psychiatric disorders among a population-based sample of adolescents from Beirut recruited through a two-stage cluster sampling design. Recruited participants (n = 510) and their parents completed a battery of questionnaires and interviews including the Development and Wellbeing Assessment (DAWBA) and the Peer-Relations Questionnaire (PRQ). We found that around 30% of the adolescent participants were involved in bullying. Younger age, lower family income, lower parental education, receiving private tutoring, having an anxiety disorder and having a disruptive behavior disorder were correlated with being bullied by peers while lower family income, repeating a school-grade, and having a disruptive behavior disorder were associated with bullying others. Several factors including gender, age group, family income, and attending private versus public schools moderated the relationship between bullying behavior and having psychiatric disorders. Our findings thus highlight the complexity of the association between psychiatric disorders and bullying in settings like Lebanon.

Childhood conduct problems and young adult outcomes among women with childhood attention-deficit/hyperactivity disorder (ADHD)

We tested whether conduct problems predicted young adult functioning and psychiatric symptoms among women diagnosed with attention-deficit/hyperactivity disorder (ADHD) during childhood, in the context of 3 potential adolescent mediators: internalizing problems, peer rejection, and school failure and disciplinary problems. We controlled for childhood ADHD severity, IQ, and demographic factors, and in the mediational tests, for adolescent conduct problems. Data came from 140 participants in the Berkeley Girls With ADHD Longitudinal Study. We used bootstrapping methods to assess indirect effects (mediators). Both childhood, F(1, 118) change = 9.00, p = .003, R2 change = .069, and adolescent, F(1, 109) change = 10.41, p = .002, R2 change = .083, conduct problems were associated with worse overall functioning during young adulthood, controlling for initial ADHD severity, child IQ, and demographics. Results were similar when predicting psychiatric symptoms. Adolescent school failure and disciplinary problems mediated the relations between childhood conduct problems and both young adult functioning and externalizing problems; adolescent internalizing problems and peer conflict mediated the relation between childhood conduct problems and young adult internalizing problems. As is true for boys, childhood and adolescent conduct problems are associated with poor adult outcomes among girls with ADHD, with school failure and disciplinary problems, internalizing problems, and peer conflict functioning as mediators of these relations.

Problematic Peer Functioning in Girls with ADHD: A Systematic Literature Review

Objective

Children with attention deficit hyperactivity disorder (ADHD) experience many peer interaction problems and are at risk of peer rejection and victimisation. Although many studies have investigated problematic peer functioning in children with ADHD, this research has predominantly focused on boys and studies investigating girls are scant. Those studies that did examine girls, often used a male comparison sample, disregarding the inherent gender differences between girls and boys. Previous studies have highlighted this limitation and recommended the need for comparisons between ADHD females and typical females, in order to elucidate the picture of female ADHD with regards to problematic peer functioning. The aim of this literature review was to gain insight into peer functioning difficulties in school-aged girls with ADHD.

Methods

PsychINFO, PubMed, and Web of Knowledge were searched for relevant literature comparing school-aged girls with ADHD to typically developing girls (TDs) in relation to peer functioning. The peer relationship domains were grouped into ‘friendship’, ‘peer status’, ‘social skills/competence’, and ‘peer victimisation and bullying’. In total, thirteen studies were included in the review.

Results

All of the thirteen studies included reported that girls with ADHD, compared to TD girls, demonstrated increased difficulties in the domains of friendship, peer interaction, social skills and functioning, peer victimization and externalising behaviour. Studies consistently showed small to medium effects for lower rates of friendship participation and stability in girls with ADHD relative to TD girls. Higher levels of peer rejection with small to large effect sizes were reported in all studies, which were predicted by girls’ conduct problems. Peer rejection in turn predicted poor social adjustment and a host of problem behaviours. Very high levels of peer victimisation were present in girls with ADHD with large effect sizes. Further, very high levels of social impairment and social skills deficits, with large effect sizes, were found across all studies. Levels of pro-social behaviour varied across studies, but were mostly lower in girls with ADHD, with small to large effect sizes. Overall, social disability was significantly higher among girls with ADHD than among TD girls.

Conclusion

Congruous evidence was found for peer functioning difficulties in the peer relationship domains of friendship, peer status, social skills/competence, and peer victimisation and bullying in girls with ADHD.

Childhood Attention-Deficit/Hyperactivity Disorder Predicts Intimate Partner Victimization in Young Women

Attention-deficit/hyperactivity disorder (ADHD) is associated with interpersonal dysfunction during childhood and adolescence, yet little is known about the romantic relationships of young women with childhood ADHD. In the present study, we draw from a longitudinal sample of girls followed prospectively into young adulthood, comparing those with (n = 114) and without (n = 79; comparisons) childhood ADHD in terms of their risk for physical victimization by an intimate partner (physical IPV; e.g., slapping, punching) by 17-24 years of age. We examined ADHD both diagnostically and dimensionally, at the same time establishing reliable indicators of young adult physical IPV. Externalizing and internalizing problems, and academic achievement during adolescence, were tested as potential mediators. Overall, participants with a childhood diagnosis of ADHD experienced more physical IPV than did comparisons (30.7% vs. 6.3%). In parallel, IPV was associated with higher levels of childhood ADHD symptomatology (d = 0.73). Young women with persistent ADHD stood the highest risk of experiencing IPV (37.3%), followed by those with transient ADHD (19.0%) and those never-diagnosed (5.9%). Academic achievement measured during adolescence was a significant partial mediator of the childhood ADHD symptomatology-young adult IPV relationship, even with control of sociodemographic, psychiatric, and cognitive factors, including childhood reading and math disorders. Findings indicate that in young women, childhood ADHD is a specific and important predictor of physically violent victimization in their intimate relationships. This vulnerable population requires IPV prevention and intervention, with academic empowerment as a key target.

Patterns of Comorbidity Among Girls With ADHD: A Meta-analysis

CONTEXT

Although children with attention-deficit/hyperactivity disorder (ADHD) are at elevated risk for comorbid psychopathology, the clinical correlates of ADHD in girls are far less understood relative to boys, despite ADHD being one of the most common childhood disorders in girls.

OBJECTIVE

To meta-analytically summarize rates of comorbid internalizing (anxiety, depression) and externalizing (oppositional defiant disorder [ODD], conduct disorder [CD]) psychopathology among girls with and without ADHD.

DATA SOURCES

Literature searches (PubMed, Google Scholar) identified published studies examining comorbid psychopathology in girls with and without ADHD.

STUDY SELECTION

Eighteen studies (1997 participants) met inclusion criteria and had sufficient data for the meta-analysis.

DATA EXTRACTION

Odds ratios for each comorbid disorder were calculated from available data. Demographic (eg, age, race/ethnicity) and study characteristics (eg, referral source, diagnostic method) were also coded.

RESULTS

Compared with girls without ADHD, girls with ADHD were significantly more likely to meet Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for each comorbid disorder assessed. Relative odds were higher for externalizing (ODD: 5.6×; CD: 9.4×) relative to internalizing disorders (anxiety: 3.2×; depression: 4.2×). Meta-regression revealed larger effect sizes of ADHD on anxiety for studies using multiple diagnostic methods, featuring younger children, and including clinic-referred (versus community-referred) girls; the effect of ADHD on ODD varied based on diagnostic informant.

LIMITATIONS

Findings were derived from cross-sectional studies, precluding causal inferences.

CONCLUSIONS

Girls with ADHD frequently exhibit comorbid externalizing and internalizing disorders. We discuss future research priorities and consider intervention implications for ADHD and comorbid psychopathology in girls.

Longitudinal Associations Between Internalizing and Externalizing Comorbidities and Functional Outcomes for Children with ADHD

This study examined functional outcomes for children with ADHD by comorbidity status. Children with ADHD (5-13 years) were recruited from 21 pediatric practices and followed up 12 months later (n = 199). Parent and teacher-reported baseline and 12 month surveys measured peer problems, daily functioning, quality of life (QoL), parent mental health, and family QoL. The Anxiety Disorders Interview Schedule for Children IV assessed mental health comorbidities at baseline. Linear regression models were conducted, adjusting for socio-demographics, ADHD severity, and baseline functioning (where possible). In adjusted analyses, children with ADHD and co-occurring internalizing and externalizing comorbidities had poorer QoL, greater peer problems, and poorer family QoL, compared to children with ADHD alone. The parents of children with ADHD and internalizing and externalizing comorbidities alone, also reported poorer family QoL, compared to children with ADHD alone. Children with ADHD and co-occurring internalizing and externalizing comorbidities appear particularly vulnerable to poorer functioning.

Symptoms of attention-deficit/hyperactivity disorder and peer functioning: a transactional model of development

The goals of this short-term longitudinal study were to investigate differential, independent effects of inattention and hyperactivity/impulsivity on children's peer relationships and the dynamic, transactional interplay between ADHD symptoms and indices of peer functioning over time. This study used a community sample that included 739 preadolescents (239 fourth graders and 500 fifth graders; 52.23 % boys) from northern Taiwan, who were assessed every six months at three time points. Children's ADHD symptoms were measured using the parent report on the Swanson, Nolan, and Pelham, version IV scale. Positive and negative facets of peer functioning, including peer rejection, peer acceptance, and the number of friendships, were assessed via peer nomination. Results of cross-lagged models indicated that inattention, but not hyperactivity/impulsivity, predicted subsequent peer impairment (i.e., lower peer acceptance and fewer dyadic friendships). Findings also showed a vicious cycle in which inattentive symptoms predicted later peer impairment, which in turn led to increases in both inattention and hyperactivity/impulsivity. These findings did not differ across gender, and the majority of the findings remained significant even after controlling for age and physical aggression. Taken together, this study demonstrated the detrimental effect of inattention on children's peer functioning and the transactional and dynamic interplay between inattention and peer impairment in a Chinese culture.

Gender differences in adults with attention-deficit/hyperactivity disorder: A narrative review

Certain characteristics of attention-deficit/hyperactivity disorder (ADHD) in children have long been known to differ by gender. What has not been as widely studied is whether gender is similarly associated with ADHD differences in adults. In this review, the relation between gender and adult ADHD prevalence, persistence, impairment, comorbidity, cognitive functioning, and treatment response was examined across 73 studies. Although gender was related to several characteristics and correlates of adult ADHD, it appeared that many of these gender differences may be at least be partially attributed to methodological artifacts or social and cultural influences, rather than fundamental differences in the expression of ADHD in men and women. We highlight how understanding the nature of the relation between gender and ADHD across the lifespan is complicated by a number of methodological difficulties, and offer recommendations for how emerging research and clinical practice can better incorporate gender into the conceptualization of ADHD in adulthood.

A review of attention-deficit/hyperactivity disorder in women and girls: uncovering this hidden diagnosis

OBJECTIVE

To describe the clinical presentation of attention-deficit/hyperactivity disorder (ADHD) in women and girls and factors influencing proper diagnosis and treatment.

DATA SOURCES

A PubMed search was conducted in April 9, 2012 for English-language publications from the previous 10 years. Search terms included attention deficit hyperactivity disorder, attention deficit/hyperactivity disorder, ADHD, and AD/HD combined with gender, girls, females, women, continuity, discontinuity, gap, treatment, untreated, and lack of treatment.

STUDY SELECTION/DATA EXTRACTION

A total of 41 articles were reviewed for relevance. Reference lists from relevant articles were reviewed for additional publications; sources known to the authors were also included.

RESULTS

Attitudes about ADHD among individuals with ADHD and knowledgeable informants (families, teachers, colleagues) vary on the basis of the diagnosed individual's gender. The ADHD prevalence rates are higher among boys than girls. A low index of clinical suspicion exists for girls; their presentation is considered "subthreshold" because inattentiveness is more prominent than hyperactivity/impulsivity. Females with ADHD may develop better coping strategies than males to mask their symptoms. Lastly, anxiety and depression, common comorbidities in female patients with ADHD, can lead to missed or misdiagnosis. If not properly diagnosed and treated, girls with ADHD experience the same negative consequences as boys, including poor academic performance and behavioral problems. Unique issues related to hormonal effects on ADHD expression and treatment response are also experienced by women and girls.

CONCLUSIONS

Accurate ADHD diagnosis in women and girls requires establishing a symptom history and an understanding of its gender-specific presentation. Coexisting anxiety and depression are prominent in female patients with ADHD; satisfactory academic achievement should not rule out an ADHD diagnosis.

Distinguishing among disruptive behaviors to help predict high school graduation: does gender matter?

This study examined unique predictive associations of aggressive and hyperactive-inattentive behaviors in elementary school with high school graduation. The current study also investigated whether these associations were moderated by gender. At Time 1, 745 children in the 3rd through 5th grades completed peer ratings on their classmates' disruptive behaviors. At Time 2, school records were reviewed to determine whether students graduated within four years of entering high school. Results showed that gender and hyperactivity-inattention are uniquely associated with high school graduation, but childhood aggression is not. Results also indicated that gender moderated associations between hyperactivity-inattention and graduation. Among boys, hyperactive-inattentive behaviors were not significantly associated with graduation, above and beyond aggression. In contrast, among girls, hyperactive-inattentive behaviors in childhood were significantly associated with graduation even after controlling for aggression. These findings suggest that in middle childhood, hyperactive-inattentive behaviors may be a more meaningful predictor of high school graduation than other forms of early disruptive behavior (e.g., aggression), especially for girls. Such findings could have significant implications for prevention and intervention programs designed to target children at risk for dropping out of school.

The Link between Peer Relations, Prosocial Behavior, and ODD/ADHD Symptoms in 7-9-Year-Old Children

Oppositional defiant disorder (ODD) and attention-deficit/hyperactivity disorder (ADHD) are characterized by symptoms that hinder successful positive interaction with peers. The main goal of this study was to examine if the presence of symptoms of ODD and ADHD affects the relationship between positive social behavior and peer status found in 7–9-year-old children who show symptoms typical of ADHD and/or ODD. Furthermore, the possible interaction with sex was investigated. We used data collected in the first wave of The Bergen Child Study of mental health (BCS), a prospective longitudinal total population study of children's developmental and mental health. The target population consisted of children in the second to the fourth, in all public, private, and special schools in Bergen, Norway, in the fall of 2002 (N = 9430). All 79 primary schools in Bergen participated in the study. Both teacher (8809 complete cases) and parent (6253 complete cases) report were used in the analyses. ADHD and ODD scores were estimated using the Swanson Noland and Pelham rating scale version IV (SNAP-IV), and peer problems and prosocial behavior were assessed using the Strengths and Difficulties Questionnaire (SDQ). We replicated the relationship between peer problems and prosocial behavior found previously in typically developing children. Our results showed that the relationship between peer problems and prosocial behavior became weaker as the ODD symptoms increased in number and severity. For ADHD this effect was only found in the teacher report of the children. A sex effect for ODD symptoms was found only using the parent report: boys with ODD symptoms showed less prosocial behavior than girls with similar levels of ODD symptoms. Since this effect was not found using the teacher data, it may imply a situational effect (school/home) for girls with high levels of ODD. The moderator effect of ODD/ADHD was comparable for boys and girls. Our findings suggest that even if children with ADHD/ODD symptoms have the opportunity to practice their social skills in peer relationships, this is not necessarily accompanied by an increase in prosocial behavior.

Sluggish cognitive tempo among young adolescents with ADHD: relations to mental health, academic, and social functioning

OBJECTIVE

This study investigated the role of sluggish cognitive tempo (SCT) in relation to externalizing and internalizing mental health problems, academic functioning, and social functioning among young adolescents with attention-deficit/hyperactivity disorder (ADHD).

METHOD

In all, 57 youth ages 10 to 14 participated in the study. Parents rated SCT, internalizing, and externalizing symptoms, as well as social and academic impairment. Teachers rated academic and peer impairment, and intelligence and academic achievement also were assessed.

RESULTS

Above and beyond ADHD and conduct problem symptoms, SCT was associated with internalizing mental health symptoms and social problems. The association between SCT and externalizing problems or academic functioning was not significant when accounting for ADHD symptomatology and intelligence.

CONCLUSION

SCT is consistently associated with internalizing symptoms and is also associated with young adolescents' general social difficulties. When controlling for important related constructs, SCT is not associated with externalizing symptoms or academic impairment among young adolescents with ADHD.

Negative social preference in relation to internalizing symptoms among children with ADHD predominantly inattentive type: girls fare worse than boys

Despite distinct peer difficulties, less is known about the peer functioning of children with attention-deficit/hyperactivity disorder (ADHD) predominantly inattentive type (ADHD-I) in comparison to the peer functioning of children with ADHD combined type. Our purpose was to examine whether child sex moderated the relations between negative social preference and internalizing/externalizing problems in children with ADHD-I. Participants included 188 children diagnosed with ADHD-I (110 boys; ages 7-11; 54% Caucasian). Teacher ratings of the proportion of classmates who "like/accept" and "dislike/reject" the participating child were used to calculate negative social preference scores. Children, parents, and teachers provided ratings of anxious and depressive symptoms, and parents and teachers provided ratings of externalizing problems. Boys and girls did not differ on teachers' negative social preference scores. As hypothesized, however, the relation between negative social preference and internalizing symptoms was moderated by sex such that negative social preference was consistently and more strongly associated with internalizing symptoms among girls than in boys. In terms of externalizing problems, negative social preference was associated with teacher (but not parent) ratings, yet no moderation by child sex was found. Negative social preference is associated with teacher-report of externalizing problems for both boys and girls with ADHD-I, whereas negative social preference is consistently associated with girls' internalizing symptoms across child, parent, and teacher ratings. Implications for future research and interventions are discussed.

Attention-deficit/hyperactivity disorder and adverse health outcomes

Attention-deficit/hyperactivity disorder (ADHD) is defined by extreme levels of inattention-disorganization and/or hyperactivity-impulsivity. In DSM-IV, the diagnostic criteria required impairment in social, academic, or occupational functioning. With DSM-5 publication imminent in 2013, further evaluation of impairment in ADHD is timely. This article reviews the current state of knowledge on health-related impairments of ADHD, including smoking, drug abuse, accidental injury, sleep, obesity, hypertension, diabetes, and suicidal behavior. It concludes by suggesting the need for new avenues of research on mechanisms of association and the potential for ADHD to be an early warning sign for secondary prevention of some poor health outcomes.

A randomized trial of a classroom intervention to increase peers' social inclusion of children with attention-deficit/hyperactivity disorder

OBJECTIVE

Interventions for peer problems among children with attention-deficit/hyperactivity disorder (ADHD) typically focus on improving these children's behaviors. This study tested the proposition that an adjunctive component encouraging the peer group to be socially inclusive of children with ADHD would augment the efficacy of traditional interventions.

METHOD

Two interventions were compared: contingency management training (COMET), a traditional behavioral management treatment to improve socially competent behavior in children with ADHD, and Making Socially Accepting Inclusive Classrooms (MOSAIC), a novel treatment that supplemented behavioral management for children with ADHD with procedures training peers to be socially inclusive. Children ages 6.8-9.8 (24 with ADHD; 113 typically developing [TD]) attended a summer day program grouped into same-age, same-sex classrooms with previously unacquainted peers. Children with ADHD received both COMET and MOSAIC with a repeated measures crossover design. TD children provided sociometric information about the children with ADHD.

RESULTS

Whereas the level of behavior problems displayed by children with ADHD did not differ across treatment conditions, children with ADHD displayed improved sociometric preference and more reciprocated friendships, and received more positive messages from peers, when they were in MOSAIC relative to COMET. However, the beneficial effects of MOSAIC over COMET predominantly occurred for boys relative to girls.

CONCLUSIONS

Data support the concept that adjunctive procedures to increase the inclusiveness of the peer group may ameliorate peer problems among children with ADHD, and suggest the potential utility of modifying MOSAIC to be delivered in regular classroom settings.

Relations of inattention and hyperactivity/impulsivity to preadolescent peer functioning: the mediating roles of aggressive and prosocial behaviors

This study examined the structural relations of preadolescents' inattention and hyperactivity/impulsivity, aggressive and prosocial behaviors, and peer functioning. There were 739 fourth (n = 239) and fifth (n = 500) graders (52.23% boys) in Taiwan who participated in this study. Preadolescents' inattention and hyperactivity/impulsivity were assessed using parent reports on the Swanson, Nolan, and Pelham IV Rating Scale. Aggressive behaviors, including physical aggression and relational aggression, and prosocial behaviors were assessed using teacher and peer reports. Peer acceptance and the number of reciprocated friendships were obtained through peer nomination administered 6 months later after initial assessment and were combined to assess children's peer functioning. Results of structural equation modeling demonstrated that inattention was indirectly linked to impaired peer functioning through low levels of prosocial behavior, regardless of gender. In addition, inattention was directly related to less optimal peer functioning only for girls. Hyperactivity/impulsivity was neither directly nor indirectly related to impaired peer functioning in boys, although it was related to more physical and relational aggression. However, for girls, a positive and direct path existed between hyperactivity and peer functioning. Further, hyperactivity in girls was associated with more physical aggression, which in turn led to poorer peer functioning. These findings suggested that the processes related to each core domain of ADHD and peer functioning may be varied, depending on the mediating factors (e.g., aggression or prosocial behavior) and gender.
