Maternal ADHD symptom severity and mother-child dyadic synchrony: an experimental study

Depression and ADHD frequently co-occur, presenting unique challenges such as difficulties in executive functioning and reduced quality of life. Both conditions are also associated with less optimal parenting behaviors. Despite the prevalence of this comorbidity, the combined effects of maternal depressive symptoms and ADHD on child development remain underexplored, particularly in early childhood, a critical period marked by heightened brain plasticity and reliance on external regulation. This study examines how maternal depression and ADHD symptoms jointly predict children’s emotional and attentional development across the first two years of life. A sample of 156 mothers and children (51% boys) participated in a three-wave longitudinal study from pregnancy to two years postpartum. Maternal ADHD symptoms were reported during pregnancy, while depressive symptoms were reported at pregnancy, three months, and two years postpartum. At two years of age, child depressive symptoms were reported by mothers, and focused attention was observed during a structured play session. Findings revealed that the combination of high maternal ADHD and depressive symptoms in the perinatal period predicted the most significant difficulties in children at two years of age, including elevated depressive symptoms and reduced focused attention. Specifically, maternal depressive symptoms were associated with greater child depressive symptoms and lower focused attention only when maternal ADHD symptoms were elevated. These results highlight the compounding effects of maternal psychopathology on child development, emphasizing the importance of targeted support for children at heightened risk of emotional and cognitive impairments due to parental psychopathology.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10802-025-01332-y.

The current study investigated the influence of maternal ADHD symptoms on: (a) mothers' own social functioning; (b) their child's social functioning; and (c) parent-child interactions following a lab-based playgroup involving children and their peers. Participants were 103 biological mothers of children ages 6-10. Approximately half of the children had ADHD, and the remainder were comparison youth. After statistical control of children's ADHD diagnostic status and mothers' educational attainment, mothers' own inattentive ADHD symptoms predicted poorer self-reported social skills. Children with ADHD were reported to have more social problems by parents and teachers, as well as received fewer positive sociometric nominations from playgroup peers relative to children without ADHD. After control of child ADHD status, higher maternal inattention and hyperactivity/impulsivity each predicted children having more parent-reported social problems; maternal inattention predicted children receiving more negative sociometric nominations from playgroup peers. There were interactions between maternal ADHD symptoms and children's ADHD diagnostic status in predicting some child behaviors and parent-child relationship measures. Specifically, maternal inattention was associated with decreased prosocial behavior for children without ADHD, but did not influence the prosocial behavior of children with ADHD. Maternal inattention was associated with mothers' decreased corrective feedback and, at a trend level, decreased irritability toward their children with ADHD, but there was no relationship between maternal inattention and maternal behaviors for children without ADHD. A similar pattern was observed for maternal hyperactivity/impulsivity and mothers' observed irritability towards their children. Treatment implications of findings are discussed.

Objective: The study examined how the interplay between maternal ADHD symptoms and maternal inhibitory control and child ADHD is related to parenting behaviors. Method: The sample included 141 mothers and their 8- to 12-year-old children, 61 children with ADHD and 80 without. Parenting was measured using self-reports (i.e., overreactive and lax parenting) and observation (i.e., negative and supportive parenting). Maternal inhibitory control was measured using a neurocognitive task. Hierarchical multiple regressions were conducted to predict parenting, controlling for child sex, conduct behaviors, and parenting distress. Results: Interactions between maternal ADHD symptoms and maternal inhibitory control suggested that hyperactive–impulsive symptoms were linked to parenting negativity only when inhibitory control was low, and maternal inattention symptoms were related to lax parenting only when maternal inhibitory control was high or when children did not have ADHD. Conclusion: Results indicate the importance of maternal regulation processes in the mechanisms linking maternal ADHD with parenting.

Examine maternal and paternal ADHD and ASD symptoms in relation to very preterm (VPT) and full-term (FT) children's ADHD and ASD symptoms. In this longitudinal study, maternal- and teacher-report of child ADHD and ASD symptoms were obtained for 119 children (VPT = 79, FT = 40) at age 5-years using the Conner's Rating Scale-Revised (CRS-R) and Social Responsiveness Scale-2 (SRS-2). A biological parent completed self- and observer-report CRS-R and SRS-2, and measures of mood/affect, stress, and social support to assess psychosocial distress. Data were analyzed using mixed-effect models adjusted for covariates. Child ADHD symptoms were associated with VPT birth, maternal distress, and maternal ADHD symptoms (p ≤ 0.02), and paternal ADHD symptoms (p < 0.001). Regarding ASD, VPT birth and parental ASD symptoms were associated with child ASD symptoms (p ≤ 0.009). Parental symptoms and birth group had no interaction. VPT birth and parental psychopathology represent independent risks for ADHD and ASD.

Objective: Separate literatures have examined the associations between maternal ADHD symptoms and parenting and maternal emotion regulation (ER) and parenting. This study examined the effects of both maternal ADHD symptoms and ER on parenting. Method: This cross-sectional study used a multi-method evaluation of parenting behavior to examine the independent and interactive effects of maternal ADHD symptoms and ER on self-reported and observed parenting among 79 demographically diverse families of 5- to 10-year-old children. Results: There were significant main effects of maternal ER difficulties on negative parenting and of maternal ADHD symptoms on harsh responses to children’s negative emotions. Maternal ADHD symptoms and ER were not significantly associated with positive parenting behavior. No interaction effects were observed. Conclusion: Maternal ADHD symptoms and emotion dysregulation may uniquely contribute to parenting difficulties. Maternal ADHD symptoms were associated with difficulties responding to children’s negative emotions, whereas maternal ER was associated with difficulties with discipline practices.

Objective: Mothers raising a child with ADHD can experience high parenting stress. We evaluated if mothers’ personality traits and own ADHD symptoms could also affect parenting stress. Method: 430 biological mothers from the Multimodal Treatment Study of Children with ADHD (MTA mothers) and 237 of a local normative comparison group (LNCG mothers) were evaluated at baseline. Interactions were tested between mothers’ group and maternal personality/ADHD symptoms related to parenting stress. Results: Compared to LNCG, MTA mothers had higher parenting stress, self-reported ADHD, neuroticism, and lower conscientiousness and agreeableness. When personality and ADHD were evaluated together, ADHD symptoms interacted with mothers’ group: high maternal ADHD was positively associated with parenting stress for LNCG but not MTA mothers. Conclusion: Personality traits or ADHD characteristics do not appear operative for the high parenting stress of mothers of a child with ADHD. However, high maternal ADHD or low conscientiousness are associated with stress levels similar to raising a child with ADHD.

Objective: ADHD symptoms in adults are consistently related to stress in a variety of domains, although whether the link between ADHD symptoms and stress is direct, or accounted for or moderated by other variables, is little studied. We used a cross-sectional design to examine whether parenting self-efficacy accounts for the relation between maternal ADHD symptoms and parenting stress, and whether levels of maternal neuroticism moderate this relation. Method: A nonclinical sample of mothers of 120, six- to 12-year-old children completed surveys online. Results: Maternal ADHD symptoms were associated with parenting stress, but this relation was accounted for by parenting self-efficacy beliefs. Neuroticism did not moderate the relations among these variables. Covariate analyses indicated that although parenting self-efficacy beliefs remain a robust predictor of parenting stress, the relation between maternal ADHD symptoms and parenting stress can be better accounted for by other variables. Conclusion: The results highlight the importance of self-efficacy beliefs and demonstrate that ADHD symptoms are not sufficient to understand the experience of parenting.

The relationship between maternal ADHD symptoms and maternal language was examined in a community sample of 50 mothers of infants age 3–12 months. It was hypothesized that higher maternal symptoms of ADHD would be related to lower quality of maternal language use. Recordings of mothers’ speech were coded for complexity and elaboration of speech and vocabulary diversity during an interview with an adult and during mother–infant play interactions in the home. Hierarchical regression analysis revealed that maternal ADHD symptoms were significantly related to mothers’ lower mean length of utterances during the interview and during mother–infant play interactions. Maternal ADHD symptoms were not related to maternal vocabulary use in either of these situations. Our findings suggest that mothers with higher ADHD symptoms may display exiguous language behaviors when interacting with their infants and with adults. In addition, findings suggest one reason why current parent-management programs for children with ADHD, which are verbally based and rely heavily on the parent’s communication skills, are relatively ineffective when ADHD may be present in the parent.

Parents with ADHD may be at increased risk to engage in physical child abuse and, in turn, influence the developing child abuse risk of their children. The present study investigated the connection between maternal ADHD symptoms and their emerging adult child’s physical abuse risk, considering potential paths via maternal child abuse risk, maternal parenting style, and the child’s ADHD symptoms. The sample included 794 emerging adults and 146 of their mothers. Emerging adults and their mothers both reported on the ADHD symptoms of the mother, the ADHD symptoms of the emerging adult child, and the mothers’ parenting style. Each also independently reported on their own physical child abuse risk. Models indicate maternal ADHD predicted emerging adult children’s abuse risk directly and indirectly through the children’s ADHD symptoms but only weakly through parenting style and not through mothers’ child abuse risk. Child abuse risk appears related to ADHD symptoms in both generations, representing an area to address clinically to reduce the intergenerational patterns of child abuse risk.

BackgroundAttention-Deficit Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD) are two of the most frequently-observed neurodevelopmental disorders. Autistic traits are detected frequently in children who have ADHD. This study aimed to examine autism symptoms in children diagnosed with ADHD and their parents; and also, to investigate parental risk factors that increase autistic traits in children. Besides the risk factors related to pregnancy, birth and developmental history were examined.MethodsTwo groups were created consisting of 66 children diagnosed with ADHD and 33 children not diagnosed with ADHD and their parents. Autism symptoms were screened with the Autism Behavior Checklist (ABC) in children, and Autism Spectrum Quotient (AQ) in parents. Also, Adult ADD/ADHD DSM-IV Based Diagnostic Screening and Rating Scale and Wender Utah Rating Scale (WURS) were used to determine ADHD symptoms in parents.ResultsIt was determined that there were more autism symptoms in children who were diagnosed with ADHD than in the control group without ADHD. There were more autistic symptoms in boys and the presence of Oppositional Defiant Disorder (ODD). Although there were more ADHD symptoms in the parents of children diagnosed with ADHD, it was determined that they did not differ from parents in the control group in terms of autism symptoms. It was also determined that maternal and paternal ADHD symptoms were predictive for autism symptoms in children. It was also shown that maternal smoking during pregnancy is associated with more autistic traits.ConclusionASD and ADHD show high levels of comorbidity. The etiology remains unclear. Both ADHD and ASD show strong hereditary transition. We found that maternal and paternal ADHD symptoms predict autism symptoms in children with ADHD. However, more studies are needed to reveal the etiology.

Very preterm (VPT; <30weeks gestation) children are a heterogeneous group, yet the co-occurrence of psychiatric and neurodevelopmental impairments remains unclear. Moreover, the clinical and socio-environmental factors that promote resilient developmental outcomes among VPT children are poorly understood. One hundred and twenty five children (85 VPT and 40 full-term) underwent neurodevelopmental evaluation at age 5-years. Parents and teachers completed measures of internalizing, externalizing, attention-deficit/hyperactivity (ADHD), and autism symptoms. Psychiatric and neurodevelopmental measures were analyzed using Latent Profile Analysis. Multinomial regression examined the extent that infant, sociodemographic, and family factors, collected prospectively from birth to follow-up, independently differentiated resilient and impaired children. Four latent profiles were identified, including a Typically Developing Group which represented 27.1% of the VPT group and 65.0% of the full-term group, an At-Risk Group with mild psychiatric and neurodevelopmental problems (VPT 44.7%, full-term 22.5%), a Psychiatric Group with moderate-to-severe psychiatric ratings (VPT 12.9%, full-term 10.0%), and a school-based Inattentive/Hyperactive Group (VPT 15.3%, full-term 2.5%). Clinical diagnoses were highest among the Psychiatric Group (80%). Factors that differentiated resilient and impaired subgroups of VPT children included prolonged exposure to maternal psychosocial distress (p≤.04), current family dysfunction (p≤.05), and maternal ADHD symptoms (p≤.02), whereas social risk index scores differentiated resilient and impaired full-term children (p<.03). Lower levels of maternal distress, family dysfunction, and maternal ADHD symptoms were associated with resilience among VPT children. Maternal distress and family dysfunction are modifiable factors to be targeted as part of psychiatric interventions embedded in the long-term care of VPT children.

This study examined how ADHD symptoms in mothers of children with ADHD relate to their behavior during parent-child interactions and to their children's disruptive behavior. Findings indicated that mothers’ retrospective self-ratings of ADHD symptoms were related to their present negativity during parent-led play. Mothers’ self-ratings of current inattentive symptoms were related to their impatience during child-led play. Maternal ADHD symptoms were also related to their ratings of their children's ADHD and oppositional-defiant behaviors. Identifying relations between maternal psychopathology, such as ADHD symptomatology, and behaviors during parent-child interactions may yield clues to additional parent behavioral changes that would enhance treatment outcomes for young children with ADHD.

High quality of mother-child interaction is associated with better psychosocial outcomes in children. However, this association might depend on the context in which mother-child interaction is observed as well as specific child characteristics. In this study, we examine differences in the assessment of mother-child interaction in a free-play and a structured task context. In addition, it will be investigated whether the behaviors per context are differently associated with preterm vs. term born toddlers' psychosocial outcomes. A total of 201 Dutch mother-child dyads participated in the study, of whom 108 children were moderate to late preterm (MLP) and 93 were born at term. Mother-child interaction was observed in a free-play and a structured task context when the child was 18 months of (corrected) age. Six subscales of mother-child interaction were assessed using the Coding Interactive Behavior scheme: maternal stimulation, maternal warmth, child's negative affect, active mother and child engagement, dyadic synchrony and tense interaction. Psychosocial outcomes were assessed at 24 months of (corrected) age using the Ages and Stages Questionnaire - Social Emotional and the Child Behavior Checklist. Mother-child interaction was reliably assessed (α > .60) in each context, except for tense interaction during free-play (α = .41) and child's negative affect when averaged across contexts (α = 0.55). Compared to the free-play context, during the structured task, more child's negative affect, tense interaction and active mother and child engagement was observed in MLP and term born children, and less dyadic synchrony in MLP children (p's < .01). Only during a structured task and for term born children, active mother and child engagement was related to less social-emotional difficulties, internalizing and externalizing behaviors. Only during free-play and for MLP children, active mother and child engagement was related to less externalizing behaviors. Dyadic synchrony during a structured task was associated with less social-emotional difficulties in MLP and term born children, and dyadic synchrony during free-play was only associated with less social-emotional difficulties in term born children (all p's < .05). Most mother-child interactive behaviors can be reliably assessed in both contexts. The structured task context elicited more varied behaviors than the free-play context. With the observations in the structured task context, more associations with children's psychosocial outcomes were found than with the observations in the free-play context. Mother-child interactions characterized by active, engaged and synchronous behaviors were associated with better psychosocial outcomes in toddlers, with some differences observed for MLP vs. term born children and for the free-play vs. the structured task context. Suggestions for future research as well as clinical practice are provided.

The relations between maternal and child ADHD symptoms and interpersonal behaviour were examined. Mother-child dyads (N = 59), with children 8- to 12-years-old, exhibiting a range of ADHD symptoms, participated in a problem-solving task. Participants' interpersonal behaviours (along continuums of affiliation: friendliness-hostility and control: dominance-submissiveness) were coded on a continuous moment-to-moment basis, as the interaction unfolded, using a joystick technique. Elevated ADHD symptoms, in both mothers and children, were associated with less overall affiliative interpersonal behaviour. Further, while dyads generally showed complementary behaviour, dyads in which the child had elevated ADHD symptoms demonstrated less complementarity on the affiliation dimension. Finally, the higher the child's ADHD symptoms, the less affiliative and less dominant the mother became over the course of the interaction. Findings highlight ways in which individual differences in ADHD behaviour impact interpersonal functioning and have implications for interventions aimed at enhancing parent-child relationships.

Interpersonal synchrony refers to the temporal coordination between two individuals, signaling the coupling of their behaviors. Optimal movement synchrony in dyads is linked to more affiliative behavior, cooperation, and trust. However, there is limited research on how the sensory environment impacts interpersonal synchrony. One significant environmental factor influencing human behavior and social interactions is ambient odors. This study aimed to examine the effect of ambient odor on interpersonal synchrony, particularly in-phase movement synchrony. Motion energy analysis and windowed cross-correlations were used to measure synchrony levels between participants during video-recorded interactions. Twenty-five same-sex friend dyads performed three interaction tasks designed to create fun, cooperative, or competitive atmospheres. These tasks were conducted with a pleasant, stimulating peppermint odor or in a control condition without odor. Consistent with previous studies, higher synchrony levels were observed in fun atmospheres compared to competitive and cooperative ones. No significant effects of odor stimulation were found. Overall, the results confirm that social context significantly influences movement synchrony and affiliation, while ambient odor might not affect interpersonal synchrony, at least when the odor is irrelevant to the task.
