Parenting of 7-month-old infants at familial risk for ADHD during infant's free play, with restrictions on interaction

Parent ADHD Is Associated With Greater Parenting Distress in the First Year Postpartum

OBJECTIVE

Little is known about the experience of parenting infants when a mother or father has ADHD. This study examined cross-sectional predictors of parenting distress experienced by parents with and without ADHD who also have infants.

METHODS

Participants were 73 mother-father pairs (N = 146) of infants 6 to 10 months old. Half of the families included a parent with ADHD. Psychosocial predictors were tested using multilevel modeling.

RESULTS

Parent or partner ADHD, lower parent sleep quality, fewer social supports, and less infant surgency and effortful control were associated with greater parental distress. Infant negative affect and sleep were not associated.

CONCLUSIONS

Parents with ADHD and their partners experience greater parenting distress in the first year of their child's life than parents without ADHD. Addressing parent ADHD symptoms and co-occurring difficulties, including sleep disturbances, are potential targets for early interventions to maximize both parent and infant mental health outcomes.

Communication between infant boys and their mothers with ADHD symptoms

AIM

This preliminary longitudinal study examined timing features and type of interaction between infant boys and their mothers with attention deficit hyperactivity disorder (ADHD) symptoms METHOD: Ten infants and their mothers with ADHD symptoms and 10 control dyads were video recorded at home during free play interactions when infants were 2-, 4-, 6-, and 9-month old. Microanalysis of the video recordings was carried out to assess synchronization, turn-taking, and type of interaction. Infants' temperament was also assessed RESULTS: ADHD dyads showed shorter synchronization at 2 months and shorter duration of Joint Attention. Partial least squares regression analysis revealed that infant's ability for Joint Attention is predicted mainly by duration of maternal behavior as well as by earlier forms of communication, that is, protoconversations.

CONCLUSION

The data from our preliminary study suggest that mothers with ADHD symptoms may have difficulties maintaining their behavior for enough time possibly due to the core symptoms of the disorder, that is, inattention, hyperactivity, and impulsivity. This maternal deficit seems to affect temporal coordination with their infants and maybe the development of more complex forms of interaction. Clinical implications of these findings are also discussed.

A Systematic Review Comparing the Play Profiles of Children with Special Health Care Needs with Typically Developing Children

INTRODUCTION

Although play has been used as a means to meet therapeutic goals by health care practitioners for a long time, there is a need to continuously review its conceptualisation and use in everyday practice to promote evidence-based practice. This systematic review aimed to evaluate the evidence on how the play of children with Special Health Care Needs (SHCN) is similar or different to that of typically developing children.

METHODS

Guided by the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement, we conducted a comprehensive review across five electronic databases for all studies that compared how the play of children with SHCN was similar or different to that of typically developing children. Data were extracted from the included studies, and methodological quality was assessed.

RESULTS

Eighteen studies met eligibility criteria. All the studies in this review were at risk of bias due to the study design. There was great variation in sample sizes, ranging between five and 112 participants in the diagnostic groups and five and 546 participants in control groups (typically developing children). The included studies investigated different aspects of play, which made it difficult to synthesise. However, of the 18 studies reviewed, thirteen reported that children with SHCN engage in less play, compared with typically developing children.

CONCLUSIONS

Evidence supports the assumption that children with SHCN are less playful and spend less time engaging in play compared with typically developing children. This systematic review reveals paucity of research on play for children with several common chronic conditions such as HIV/AIDS, cancer, and cardiovascular diseases. Future studies need to reduce risks of bias, including the use of appropriate sample sizes, and must provide detailed results after investigating play in children with SHCN.

Catechol-O-methyltransferase Val158Met Genotype and Early-Life Family Adversity Interactively Affect Attention-Deficit Hyperactivity Symptoms Across Childhood

Attention-deficit hyperactivity disorder (ADHD) is among the most commonly diagnosed psychiatric disorders of childhood. The dopaminergic system has been shown to have substantial effects on its etiology, with both functional Catechol-O-methyltransferase (COMT) Val158Met genotype and early-life environmental adversity involved in the risk of inattention and hyperactivity/impulsivity symptoms. In this prospective longitudinal study, we examined for the first time the impact of proximal and distal early-life family adversity and COMT Val158Met polymorphism gene - both the direct and the interactive effects, on children's ADHD symptoms across childhood. Data came from the Family Life Project, a prospective longitudinal study of 1,292 children and families in high poverty from birth to 11 years. In infancy, data regarding socioeconomic (SES)-risk-factors, observed-caregiving behaviors, and DNA genotyping were collected. In early and middle childhood teachers rated the occurrence and severity of the child's ADHD symptoms. Multilevel growth curve models revealed independent effects of COMT, early-life SES-risk and negative caregiving on ADHD symptoms in early and middle childhood. Significant gene-environment interactions were found, indicating that overall, carriers of at least one COMT158Met allele were more sensitive to early-life adversity, showing higher inattention and hyperactivity/impulsivity symptoms severity in childhood when exposed to high SES-risk factors in infancy, compared to Val-Val carriers. Findings provide new insights into the complex etiology of ADHD and underline the need for further investigation of the neuronal mechanisms underlying gene-environment interactions. Findings might have implications for prevention and intervention strategies with a focus on early-life family relationships in genetically at-risk children.

The Contribution of Maternal ADHD Symptomatology, Maternal DAT1, and Home Atmosphere to Child ADHD Symptomatology at 7 Years of Age

Children of mothers with attention-deficit/hyperactivity disorder (ADHD) have an increased genetic and environmental risk for ADHD. The unique and interactive contributions of a maternal dopamine receptor gene (DAT1), maternal ADHD symptoms (hyperactive- impulsive, inattentive), and home atmosphere to the prediction of ADHD symptoms (hyperactive- impulsive, inattentive) in 7- year-old boys (N = 96) were examined using data from a longitudinal study of familial risk for ADHD. During the first 6 months of the study, mothers and their spouses completed a questionnaire about the mother's ADHD symptoms. Home atmosphere questionnaire data were collected 4 years later. At the 7-year assessment, mothers reported on their child's ADHD symptoms. Negative home atmosphere was significantly associated with child hyperactive-impulsive and inattentive symptoms. Maternal inattentive symptoms were significantly correlated with both child symptom dimensions. Regression models, with child genotype and maternal education controlled, showed main effects for maternal inattentive symptoms, maternal DAT1 10/10 genotype, and home atmosphere in the prediction of child inattentive symptoms. Only home atmosphere predicted child hyperactive-impulsive symptoms. There was a significant home atmosphere x maternal hyperactive-impulsive symptoms interaction in the prediction of child hyperactive-impulsive symptoms. Boys with higher levels of symptoms came from homes characterized by higher levels of negative atmosphere and had mothers with higher levels of hyperactive-impulsive symptoms. There was also a trend (p = 0.075) for a maternal DAT1 x home atmosphere interaction. Boys with higher levels of inattentive symptoms came from homes with higher levels of negative atmosphere and had mothers with the homozygous 10/10 genotype. The maternal heterozygous 9/10 genotype did not predict child symptoms.

Serotonin transporter polymorphism moderates the effects of caregiver intrusiveness on ADHD symptoms among institutionalized preschoolers

Research consistently chronicles a variety of mental health difficulties that plague institutionally reared children, including attention-deficit/hyperactivity disorder (ADHD), even if not all institutionalized children evince such problems. In seeking to extend work in this area, this research on gene × environment (GXE) interplay investigated whether the effect of the quality of institutional care-most notably, caregiver intrusiveness-on ADHD symptoms is moderated by the serotonin transporter (5-HTTLPR) polymorphism. One hundred and twenty-seven institutionalized preschoolers were evaluated using the Child Behavior Checklist. Caregiver-rated attention problems and hyperactivity were unrelated to both 5-HTTLPR polymorphism and caregiver intrusiveness. A significant GXE effect, independent of age at placement or duration of institutionalization, emerged, however, consistent with the differential-susceptibility hypothesis: s/s homozygotes manifest the most and least ADHD symptoms when they experienced, respectively, more and less intrusive caregiving. These results provide new insight into the reasons why some institutionalized children, but not others, exhibit ADHD symptoms.

Early identification of ADHD risk via infant temperament and emotion regulation: a pilot study

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) is theorized to have temperamental precursors early in life. These are difficult to identify because many core features of ADHD, such as breakdowns in executive function and self-control, involve psychological and neural systems that are too immature to reliably show dysfunction in early life. ADHD also involves emotional dysregulation, and these temperamental features appear earlier as well. Here, we report a first attempt to utilize indices of emotional regulation to identify ADHD-related liability in infancy.

METHODS

Fifty women were recruited in the 2nd trimester of pregnancy, with overselection for high parental ADHD symptoms. Measures of maternal body mass index, nutrition, substance use, stress, and mood were examined during pregnancy as potential confounds. Offspring were evaluated at 6 months of age using LABTAB procedures designed to elicit fear, anger, and regulatory behavior. Mothers completed the Infant Behavior Questionnaire about their child's temperament.

RESULTS

After control for associated covariates, including maternal depression and prenatal stress, family history of ADHD was associated with measures of anger/irritability, including infant negative vocalizations during the arm restraint task (p = .004), and maternal ratings of infant distress to limitations (p = .036). In the regulation domain, familial ADHD was associated with less parent-oriented attention seeking during the still face procedure (p < .001), but this was not echoed in the maternal ratings of recovery from distress.

CONCLUSIONS

Affective response at 6 months of age may identify infants with familial history of ADHD, providing an early indicator of ADHD liability. These preliminary results provide a foundation for further studies and will be amplified by enlarging this cohort and following participants longitudinally to evaluate ADHD outcomes.

[Associations with ADHD and parental distress with in play in early childhood]

OBJECTIVE

According to Papoušek (2004), "disinterests in play" in early childhood is a possible early indicator of AD(H)D at school age. The phenomenon of disinterest in play is associated with psychological distress in parents and children as well as with disturbances in the parent-child-relationships Papoušek, 2003. We investigated the association between disinterest in play in early childhood and AD(H)D and their associations with maternal distress.

METHOD

Mothers of 35 children with AD(H)D [age: M (SD)= 9.0 (1.1) years; males: 30 (85.7 %)] and mothers of 42 children without AD(H)D [age: M (SD) = 8.8 (1.0) years; males: 35 (83.3 %)] gave their written informed consent to participate in the study. Using a questionnaire on the ability to play during the first 4 years of age, subjects were grouped into 39 children with lower interest in play and 38 children with higher interest in play. Maternal stress was assessed using a German adaptation of the Parenting Stress Index Abidin, 1995.

RESULTS

The rate of AD(H)D and maternal stress was significantly higher in the group of children with lower interest in play. Mothers of children showing both AD(H)D and lower interest in play scored highest, mothers of children presenting neither behavior disorder scored lowest.

CONCLUSIONS

The results agree with the assumption that disinterest in play in early childhood is associated with the development of AD(H)D and an additional stressor for mothers.

Risikofaktoren und frühe Vorläufersymptome der Aufmerksamkeitsdefizit-/Hyperaktivitätsstörung (ADHS)

Einer ADHS liegen in der Regel multiple miteinander interagierende Faktoren zugrunde. Zu den Risikofaktoren zählen neben genetischen Faktoren auch verschiedene Umwelteinflüsse wie sozioökonomische Risiken oder mütterlicher Substanzkonsum. Diese Umwelteinflüsse können jedoch teilweise auch Ausdruck einer entsprechenden genetischen Prädisposition der Eltern für eine ADHS darstellen, sodass eine klare Trennung zwischen genetischen und umweltbedingten Einflüssen auf die Entstehung der ADHS nur begrenzt möglich und sinnvoll ist. Da der Störung ein komplexes Zusammenspiel multipler voneinander unabhängiger Risikofaktoren zugrunde liegt, wird ADHS inzwischen eher im Sinne einer Dimension denn im Sinne einer Kategorie verstanden. Im Rahmen dieser Arbeit soll ein Überblick über die neuesten Erkenntnisse bezüglich Risikofaktoren und Vorläufersymptomen von ADHS gegeben werden.

Parenting in adults with attention-deficit/hyperactivity disorder (ADHD)

Although the validity of adult ADHD is well established and research has identified a variety of impairments associated with the condition in adults, study of how ADHD impacts an adult's ability to parent has been relatively neglected. Parenting is a particularly important domain of functioning given the familial nature of the disorder and emerging evidence that parenting behaviors play a role in the development or maintenance of child ADHD symptoms, comorbid psychopathologies, and other associated difficulties. In this paper, we focus on three broad categories of cognitive dysfunction proposed across models of ADHD - cognitive processes (e.g., working memory, planning, and inhibitory control), self-regulation deficits (e.g., self-monitoring of performance to detect errors or the need for regulation of behavior and/or emotions), and motivational or arousal difficulties (e.g., response to incentives, delay aversion). We consider how these deficits may lead to impairments in the parenting behaviors of effective behavioral control and emotional responsiveness, and review the available evidence regarding parenting in adults with ADHD symptoms. We conclude by noting the limitations in existing studies, and argue for further research that is theoretically grounded in how core deficits of ADHD may be related to dimensions of parenting. The implications of an improved understanding of how ADHD impacts parenting for the development of early intervention or prevention programs are outlined.
