Feasibility of an Online Acute Stressor in Preschool Children of Mothers with Depression.

Maternal depression is a risk factor for future mental health problems in offspring, with stress-system function as a candidate vulnerability factor. Here we present initial validation of an online matching-task (MT) paradigm in young children exposed to maternal depression (N = 40), a first in stressor-paradigm research for this age group. Investigations of stress-system reactivity that can be conducted online are an innovative assessment approach, accelerated by the COVID-19 pandemic. Results indicate high feasibility, with a >75% data collection success rate across measures, similar-to or better-than in-person success rates in young children. Overall, the online MT elicited significant heart rate but not cortisol reactivity. Individual differences in child mental health symptoms were a moderator of reactivity to the stressor such that children with lower, but not higher, behavioral problems exhibited the typical pattern of cortisol reactivity to the online MT. Results are aligned with allostatic load models, which suggest downregulation of stress-system reactivity as a result of experiencing adversity and mental health vulnerability. Consistent with in-person research, this suggests that an early phenotype for the emergence of behavior problems may be linked to altered stress-system reactivity. Results hold potential clinical implications for intervention development and the future of online stress-system research.

Smartphone Photoplethysmography Pulse Rate Covaries With Stress and Anxiety During a Digital Acute Social Stressor.

OBJECTIVE: Heart rate is a transdiagnostic correlate of affective states and the stress diathesis model of health. Although most psychophysiological research has been conducted in laboratory environments, recent technological advances have provided the opportunity to index pulse rate dynamics in real-world environments with commercially available mobile health and wearable photoplethysmography (PPG) sensors that allow for improved ecologically validity of psychophysiological research. Unfortunately, adoption of wearable devices is unevenly distributed across important demographic characteristics, including socioeconomic status, education, and age, making it difficult to collect pulse rate dynamics in diverse populations. Therefore, there is a need to democratize mobile health PPG research by harnessing more widely adopted smartphone-based PPG to both promote inclusivity and examine whether smartphone-based PPG can predict concurrent affective states. METHODS: In the current preregistered study with open data and code, we examined the covariation of smartphone-based PPG and self-reported stress and anxiety during an online variant of the Trier Social Stress Test, as well as prospective relationships between PPG and future perceptions of stress and anxiety in a sample of 102 university students. RESULTS: Smartphone-based PPG significantly covaries with self-reported stress and anxiety during acute digital social stressors. PPG pulse rate was significantly associated with concurrent self-reported stress and anxiety ( b = 0.44, p = .018) as well as prospective stress and anxiety at the subsequent time points, although the strength of this association diminished the farther away pulse rate got from self-reported stress and anxiety (lag 1 model: b = 0.42, p = .024; lag 2 model: b = 0.38, p = .044). CONCLUSIONS: These findings indicate that PPG provides a proximal measure of the physiological correlates of stress and anxiety. Smartphone-based PPG can be used as an inclusive method for diverse populations to index pulse rate in remote digital study designs.

The Building Regulation in Dual-Generations Program (BRIDGE): A Mixed-Methods Feasibility Pilot of a Parenting Program for Depressed Mothers of Preschoolers, Matched with Dialectical Behavior Therapy Skills.

Early exposure to maternal depression is a key risk factor for child mental illness (MI), but there are limited programs that interrupt intergenerational transmission. The BRIDGE "Building Regulation in Dual Generations" Program treats maternal MI using Dialectical Behavior Therapy Skills with a paired curriculum that promotes non-reactive and emotionally validating parenting designed to improve child mental health and ultimately prevent MI. The pilot feasibility trial (n = 28 dyads) included mothers and their preschool-aged children. The 20-week program was completed in a group-based format using mixed methods questionnaires and interviews. Results indicate high feasibility and acceptability (86% retention). Consistent improvements were seen across program targets and outcomes including maternal depression (d = 1.02) and child mental health (d = 1.08), with clinically significant symptom reductions for 85% of clients. Mothers with higher adversity exhibited greater reductions in parenting stress. Qualitative results highlighted efficacy in promoting positive parent-child relationships, rewarding parenting experiences, competence, and child development. Evidence suggests high feasibility and accessibility for BRIDGE in addressing intergenerational mental health needs. There was strong satisfaction with the program material and efficacy across key outcomes. BRIDGE holds promise for offering a transdiagnostic approach to preventing child MI in families of at-risk preschool aged children.

Pregnancy during the COVID-19 pandemic: a qualitative examination of ways of coping.

The COVID-19 pandemic and related public health restrictions have impacted the mental health and coping strategies of many population groups, including people who are pregnant. Our study sought to explore the ways that pregnant people described coping with stressors associated with the pandemic. N = 5879 pregnant individuals completed the pan-Canadian Pregnancy During the COVID-19 Pandemic Survey between April and December 2020. We used descriptive statistics to quantify sociodemographic characteristics and thematic analysis (Braun & Clarke, 2006, 2019) to analyze n = 3316 open-ended text responses to the question "Can you tell us what things you are doing to cope with the COVID-19 pandemic?" The average age of participants was 32 years (SD = 4.4), with the majority identifying as White (83.6%), female (99.7%), married (61.5%), having completed post-secondary education (90.0%), and working full-time (75.4%). We categorized participant responses into two overarching thematic dimensions: (1) ways of coping and (2) coping challenges. Ways of coping included the following main themes: (1) taking care of oneself, (2) connecting socially, (3) engaging in pandemic-specific coping strategies, (4) keeping busy, (5) taking care of others, (6) creating a sense of normalcy, (7) changing perspectives, and (8) practicing spirituality. Coping challenges included the following: (1) the perception of coping poorly, (2) loss of coping methods, (3) managing frontline or essential work, and (4) worries about the future. Findings highlight important implications for targeted prenatal supports delivered remotely, including opportunities for social support, prenatal care, and mental health strategies.

The Effectiveness of KEEP for Families of Children with Developmental Delays: Integrating FIND Video Coaching into Parent Management Training-Oregon Model: a Randomized Trial.

Children with developmental delays or disabilities (DD) are at risk for self-regulation difficulties and behaviour problems compared to typically developing children. Intervening early is crucial to prevent long-term adjustment challenges across home and school contexts. Parenting has been identified as a malleable target of intervention for improving children's adaptive functioning across behavioural, emotional and cognitive domains. Although parent management training (PMT) is an identified best-practice, key questions remain about the critical components of interventions and how novel approaches like video feedback may offer additional benefits. Using a pre-test-post-test one group and superiority design, we evaluated the efficacy of two models of the Keeping Parents Trained and Supported (KEEP) preschool program with parent-only components among 175 families with children diagnosed or at-risk for DD. KEEP-P included core PMT (Oregon Model) methods and KEEP-V integrated KEEP with Filming Interactions to Nurture Development video coaching methods for enhancing developmentally supportive interactions. Intervention outcomes on children's behaviour problems and executive functioning, parenting stress and parent-child relationship quality were compared between groups. Both groups demonstrated significant reductions over time in child behavioural problems, developmental problems and parenting stress. Significant improvements were observed in children's executive functioning, parents' sense of competence and mindfulness in parenting. Group differences were observed in parent's sense of competence, with individuals receiving KEEP-P displaying greater increases over time. Higher intervention dosage predicted a greater reduction in stressful child behaviours and greater improvements in children's inhibitory control.

Induction of acute stress through an internet-delivered Trier Social Stress Test as assessed by photoplethysmography on a smartphone.

Recent studies have demonstrated the feasibility of administering the Trier Social Stress Test (TSST) through the internet, with major implications for promoting inclusivity in research participation. However, online TSST studies to date are limited by a lack of control groups and the need for biological measures of stress reactivity that can be fully implemented online. Here, we test smartphone-based photoplethysmography as a measure of heart rate reactivity to an online variant of the TSST. Results demonstrate significant acceleration in heart rate and heightened self-reported stress and anxiety in the TSST condition relative to a placebo version of the TSST. The placebo condition led to a significant increase in self-reported stress and anxiety relative to baseline levels, but this increase was smaller in magnitude than that observed in the TSST condition. These findings highlight the potential for smartphone-based photoplethysmography in internet-delivered studies of cardiac reactivity and demonstrate that it is critical to utilize random assignment to a control or stressor condition when administering acute stress online.

High anxiety and health-related quality of life in families with children with food allergy during coronavirus disease 2019.

BACKGROUND: Food allergy has a known effect on quality of life (QoL), but this has not been extensively studied during the coronavirus disease 2019 pandemic. OBJECTIVE: To characterize the levels of anxiety of mothers of children aged 0 to 8 years with food allergy compared with families of children without a food allergy and the health-related QoL among children with food allergy during the coronavirus disease 2019 pandemic. METHODS: In a mixed-methods study, Canadian mothers of children aged 0 to 8 years with (cases) and without (controls) food allergy provided demographic data and completed age-appropriate anxiety questionnaires between April 14, 2020, and April 28, 2020. The cases also provided food allergy-related data and completed the Food Allergy Quality of Life Questionnaire. In-depth interviews were subsequently conducted with purposefully selected cases. RESULTS: In a total of 580 participants, 5.5% were cases and 94.5% were controls. For mothers of children aged 0 to 1.5 years, anxiety levels did not differ between cases and controls. For mothers of children aged 1.5 to 8 years, anxiety levels were higher in cases vs controls (P < .05). Among the cases, neither overall nor domain-specific Food Allergy Quality of Life Questionnaire scores differed between age groups (0-3 vs 4-7 years), even after adjustment for confounding variables, including childcare during the pandemic. Qualitatively, the following 3 themes were identified: unexpected challenges of food shopping; less food-related food anxiety during the pandemic; and differences and delays in food allergy testing and therapy. CONCLUSION: Mothers of children with food allergy reported high anxiety and poor health-related QoL. Yet, qualitatively, day-to-day food allergy management was better during the pandemic.

Acute stress impairs children's sustained attention with increased vulnerability for children of mothers reporting higher parenting stress.

Despite evidence that acute stress impairs attention in adults, there has been minimal research in children. Here, the effects of acute stress on Go/No-go performance were examined in young children (M age = 5.41 years). Given the critical role of the parent-child relationship to children's self-regulatory development, the extent to which parenting stress predicts children's cognitive vulnerability to acute stress and autonomic reactivity was also investigated. A between-groups design (n = 58 stress, n = 26 control) was used with oversampling of the stressor-exposed children to examine individual differences. The Parenting Stress Index and subscales were employed as a measure of parenting stress. Acute stress impaired children's sustained attention, but not inhibitory control. Higher parenting stress was associated with vulnerability to attentional impairment. Parenting distress was also positively associated with sympathetic reactivity to acute stress, but neither sympathetic nor parasympathetic reactivity was associated with attentional impairment. A conceptual model of pathways through which repetitive acute stress may contribute to self-regulatory difficulties is presented, including the potential buffering role of caregivers.

Children's biological responsivity to acute stress predicts concurrent cognitive performance.

Although prior research has characterized stress system reactivity (i.e. hypothalamic-pituitary-adrenal axis, HPAA; autonomic nervous system, ANS) in children, it has yet to examine the extent to which biological reactivity predicts concurrent goal-directed behavior. Here, we employed a stressor paradigm that allowed concurrent assessment of both stress system reactivity and performance on a speeded-response task to investigate the links between biological reactivity and cognitive function under stress. We further investigated gender as a moderator given previous research suggesting that the ANS may be particularly predictive of behavior in males due to gender differences in socialization. In a sociodemographically diverse sample of young children (N = 58, M age = 5.38 yrs; 44% male), individual differences in sociodemographic covariates (age, household income), HPAA (i.e. cortisol), and ANS (i.e. respiratory sinus arrhythmia, RSA, indexing the parasympathetic branch; pre-ejection period, PEP, indexing the sympathetic branch) function were assessed as predictors of cognitive performance under stress. We hypothesized that higher income, older age, and greater cortisol reactivity would be associated with better performance overall, and flexible ANS responsivity (i.e. RSA withdrawal, PEP shortening) would be predictive of performance for males. Overall, females performed better than males. Two-group SEM analyses suggest that, for males, greater RSA withdrawal to the stressor was associated with better performance, while for females, older age, higher income, and greater cortisol reactivity were associated with better performance. Results highlight the relevance of stress system reactivity to cognitive performance under stress. Future research is needed to further elucidate for whom and in what situations biological reactivity predicts goal-directed behavior.

Cumulative risk exposure moderates the association between parasympathetic reactivity and inhibitory control in preschool-age children.

A child's cumulative risk for early exposure to stress has been linked to alterations of self-regulation outcomes, including neurobiological correlates of inhibitory control (IC). We examined whether children's ability to engage the parasympathetic nervous system impacts how risk affects IC. Children ages 3-5 years completed two laboratory measures of IC while respiratory sinus arrhythmia (RSA) was measured, indexing parasympathetic activity. Children with greater risk demonstrated lower IC; risk also moderated associations between RSA reactivity and IC. For children with less risk, greater RSA withdrawal during IC tasks was associated with better IC. In contrast, greater risk was associated with poor IC, regardless of RSA withdrawal. Effects of risk were more pronounced for cumulative than individual measures. Results suggest that cumulative risk exposure disrupts connectivity between physiological and behavioral components of self-regulation in early childhood. Parasympathetic withdrawal to cognitive tasks may be less relevant for performance in developmental samples experiencing greater life stress.

Polyvictimization and externalizing symptoms in foster care children: The moderating role of executive function.

Prior research has identified the role of childhood maltreatment in externalizing problems and executive function (EF) deficits, but minimal work has been done to characterize the effects of co-occurring maltreatment types, defined as polyvictimization. Here, we sought to characterize the association between polyvictimization and externalizing problems in a sample of foster care children aged 3-4 years (N = 84) and examine how EF may mediate or moderate that relationship. A moderation model was supported in that only polyvictimized children with EF scores 1.62 or more standard deviations below the mean were at heightened risk for clinically severe externalizing problems, while no association between polyvictimization and externalizing problems were observed for children who scored at the mean or above on the EF measure. Findings highlight that EF may serve as a resilience factor indicating that individual differences in polyvictimized children's EF skills help to predict variability in externalizing problems. Future research on designing and optimizing intervention programs that target EF skills may mitigate the development of maladaptive outcomes for polyvictimized children.

Preliminary evidence of the impact of early childhood maltreatment and a preventive intervention on neural patterns of response inhibition in early adolescence.

Maltreated youths in foster care often experience negative developmental and psychological outcomes, which have been linked with poor response inhibition. Recent evidence suggests that childhood maltreatment is also associated with alterations in the neural circuitry underlying response inhibition. However, a burgeoning line of research has begun to explore the mitigating effects of preventive interventions on neural functioning. The current study used event-related functional magnetic resonance imaging to explore the impact of early childhood maltreatment and a preventive intervention on response inhibition in early adolescence. Thirty-six demographically similar adolescents (ages 9-14 years) completed a Go/NoGo task. The sample included nonmaltreated adolescents (n = 14) and maltreated adolescents who were in foster care as preschoolers and randomly assigned to receive services as usual (n = 11) or a preventive intervention, Multidimensional Treatment Foster Care for Preschoolers (n = 11). The groups demonstrated similar behavioral performance but significantly different neural patterns. The maltreated adolescents who received services as usual demonstrated subcortical hypoactivity during successful response inhibition and subcortical hyperactivity during unsuccessful response inhibition. In contrast, the nonmaltreated adolescents and maltreated adolescents who received the intervention exhibited strikingly similar neural patterns during successful response inhibition, but the maltreated adolescents who received the intervention demonstrated prefrontal hypoactivity during unsuccessful response inhibition. These findings offer preliminary evidence that early childhood maltreatment alters the neural patterns underlying response inhibition in early adolescence and that participating in a preventive intervention could mitigate maltreatment-related effects on these neural systems.

Effect of Housing First on Suicidal Behaviour: A Randomised Controlled Trial of Homeless Adults with Mental Disorders.

OBJECTIVE: This study attempted to determine if Housing First (HF) decreased suicidal ideation and attempts compared to treatment as usual (TAU) amongst homeless persons with mental disorders, a population with a demonstrably high risk of suicidal behaviour. METHOD: The At Home/Chez Soi project is an unblinded, randomised control trial conducted across 5 Canadian cities (Vancouver, Winnipeg, Toronto, Montreal, Moncton) from 2009 to 2013. Homeless adults with a diagnosed major mental health disorder were recruited through community agencies and randomised to HF ( n = 1265) and TAU ( n = 990). HF participants were provided with private housing units and received case management support services. TAU participants retained access to existing community supports. Past-month suicidal ideation was measured at baseline and 6, 12, 18, and 21/24 months. A history of suicide attempts was measured at baseline and the 21/24-month follow-up. RESULTS: Compared to baseline, there was an overall trend of decreased past-month suicidal ideation (estimate = -.57, SE = .05, P < 0.001), with no effect of treatment group (i.e., HF vs. TAU; estimate = -.04, SE = .06, P = 0.51). Furthermore, there was no effect of treatment status (estimate = -.10, SE = .16, P = 0.52) on prevalence of suicide attempts (HF = 11.9%, TAU = 10.5%) during the 2-year follow-up period. CONCLUSION: This study failed to find evidence that HF is superior to TAU in reducing suicidal ideation and attempts. We suggest that HF interventions consider supplemental psychological treatments that have proven efficacy in reducing suicidal behaviour. It remains to be determined what kind of suicide prevention interventions (if any) are specifically effective in further reducing suicidal risk in a housing-first intervention.

The Neurobiology of Intervention and Prevention in Early Adversity.

Early adverse experiences are well understood to affect development and well-being, placing individuals at risk for negative physical and mental health outcomes. A growing literature documents the effects of adversity on developing neurobiological systems. Fewer studies have examined stress neurobiology to understand how to mitigate the effects of early adversity. This review summarizes the research on three neurobiological systems relevant to interventions for populations experiencing high levels of early adversity: the hypothalamic-adrenal-pituitary axis, the prefrontal cortex regions involved in executive functioning, and the system involved in threat detection and response, particularly the amygdala. Also discussed is the emerging field of epigenetics and related interventions to mitigate early adversity. Further emphasized is the need for intervention research to integrate knowledge about the neurobiological effects of prenatal stressors (e.g., drug use, alcohol exposure) and early adversity. The review concludes with a discussion of the implications of this research topic for clinical psychology practice and public policy.

Inherited and environmental influences on a childhood co-occurring symptom phenotype: Evidence from an adoption study.

Risk factors for the childhood development of co-occurring internalizing and externalizing symptoms are not well understood, despite a high prevalence and poor clinical outcomes associated with this co-occurring phenotype. We examined inherited and environmental risk factors for co-occurring symptoms in a sample of children adopted at birth and their birth mothers and adoptive mothers (N = 293). Inherited risk factors (i.e., birth mothers' processing speed and internalizing symptoms) and environmental risk factors (i.e., adoptive mothers' processing speed, internalizing symptoms, and uninvolved parenting) were examined as predictors for the development of internalizing-only, externalizing-only, or co-occurring symptoms using structural equation modeling. Results suggested a unique pattern of predictive factors for the co-occurring phenotype, with risk conferred by adoptive mothers' uninvolved parenting, birth mothers' slower processing speed, and the birth mothers' slower processing speed in tandem with adoptive mothers' higher internalizing symptoms. Additional analyses indicated that when co-occurring-symptom children were incorporated into internalizing and externalizing symptom groups, differential risk factors for externalizing and internalizing symptoms emerged. The findings suggest that spurious results may be found when children with co-occurring symptoms are not examined as a unique phenotypic group.

Children's Executive Function in a CPS-Involved Sample: Effects of Cumulative Adversity and Specific Types of Adversity.

Prior research has identified the presence of executive function (EF) deficits in child protective service (CPS) involved (versus non-involved) children but minimal work has examined predictors that might explain individual differences within these CPS-involved children. Here, we sought to characterize EF in a large sample (N=694) of CPS-involved children and examine how specific adversities (physical abuse, neglect, caregiver domestic violence, and caregiver substance dependence) and cumulative adversity (at ages 0-3 and 3-6 years) predict EF (at approximately 5-6 years). It was expected that the sample would exhibit low EF overall based on previous research in maltreated children. Specific adversity and cumulative adversity analyses were largely exploratory given the limited previous work in this area. Results indicated poor EF overall, with 43.5% of children performing worse than chance. Amongst children who performed greater than chance, higher cumulative adversity, physical abuse, and caregiver substance use (at ages 3-6 years) predicted better EF. These findings join literature documenting that, within CPS-involved children, the presence of certain adversities predicts variable cognitive function. Findings highlight the potential relevance of evolutionary psychology to understanding how alterations in behavior linked to harsh and unpredictable early environments may cue accelerated brain development underlying relative cognitive advantages, within at-risk, low performing samples. Longitudinal studies are critical to determine if the relative EF advantages linked to higher adversity persist over time or result in lower EF later on, reflecting a more rapid, but overall limited, trajectory of cognitive development.

"Bottom of My Own List:" Barriers and Facilitators to Mental Health Support Use in Caregivers of Children with Neurodevelopmental Support Needs.

This study investigated barriers and facilitators to mental health service use (e.g., interventions, educational programs) in caregivers of children with neurodevelopmental disorders and/or neurodevelopmental problems, as they experience high levels of distress and low help-seeking behaviour. Caregivers of children aged 0 to 12 with neurodevelopmental disorders and/or neurodevelopmental problems (N = 78) completed a mixed-method online survey about their mental health and service use. Caregiver-reported psychological distress and mental health service use were positively correlated. Most participants (66.2%) were above the clinical cut-off score for anxiety, depression, or caregiving stress; of these participants, 45.7% had not accessed mental health services for themselves within the past year. Lack of time and difficulties arranging childcare were noted barriers; patient-oriented suggestions for service improvement were provided. The findings add novel information on factors to increase mental health service use in this population. Recommendations for clinical practice for those practitioners who provide services for children with neurodevelopmental disorders and/or neurodevelopmental problems are included.

An investigation of a novel milk allergy-friendly food supplement program.

Introduction: Compared to households not managing food allergy, households managing food allergy are faced with greater direct and indirect costs. To address these cost burdens, we developed and piloted a milk allergy-friendly food supplement program for lower- and middle-income households managing a dairy allergy in a child age <6 years. Herein, we aimed to evaluate to the impact of this program on food costs, food security, and caregiver mental health using a longitudinal design. Methods: Participants living in or near the city of Winnipeg, in Manitoba, Canada were recruited from January to February 2022 via social media, word-of-mouth, and a database maintained by the principal investigator. Consenting participants took part in a 6-month allergen-friendly food supplement program that provided them with biweekly deliveries of allergen-friendly foods free of charge. To evaluate the impact of the program on food costs, food security, and well-being, participants completed a series of questionnaires at baseline, mid-point, and at the end of the program. Changes in these variables were assessed via a series of Friedman tests. Results: The final sample was comprised of 8 households. Relative to baseline, participants reported higher total direct food costs at midpoint (+5.6%) and endpoint (+13.5%), but these changes did not reach statistical significance. In contrast, total indirect food costs decreased over the course of the study relative to baseline (midpoint = -28.2%; endpoint = -18.5%), but the changes were not found to be statistically significant. Participants did, however, report a statistically significant decrease in costs related to lost time from work or school as a result of their child's food allergy at endpoint relative to baseline (-100%). Few changes in food security, caregiver well-being, or child food allergy quality of life were noted. Discussion: The provision of allergen-friendly foods helped keep grocery costs below the pace of inflation. Participants also reported reduced costs associated with missed time from work or school as a result of their child's food allergy. Despite these encouraging findings, a relatively high proportion of the current sample reported experiencing food insecurity throughout the study period, suggesting that additional financial support for families is needed.

Infantile atopic dermatitis - increasing severity predicts negative impacts on maternal and infant sleep: a mixed methods study.

BACKGROUND: While the impacts of atopic dermatitis (AD) on maternal and child sleep outcomes have been previously explored, less is known about the associations between infantile AD and sleep quality and quantity. OBJECTIVE: To describe the perceived causes of AD-associated maternal sleep disturbances and the association between AD severity and infant sleep outcomes. METHODS: Mothers with infants aged < 19 months old with a diagnosis of AD were recruited from social media and medical clinics in Winnipeg, Canada between October 2021 and May 2022. Infant AD severity was classified using maternal-reported data on the Patient-Oriented Scoring Atopic Dermatitis tool (PO-SCORAD). Quantitative data were collected via a series of questionnaires with a subset of mothers subsequently completing semi-structured interviews. Quantitative and qualitative data were integrated in the discussion. RESULTS: Mothers of infants with moderate/severe AD (6/12) were more likely to report their infant suffering from a higher degree of sleeplessness (i.e., ≥ 5 on a scale of 0-10) over the past 48 h compared to mothers of infants with mild AD (0/18). This was supported by qualitative findings where mothers described how their infant's sleep quality and quantity worsened with AD severity. Additionally, 7/32 mothers reported that their child's AD, regardless of severity, disturbed their sleep. Maternal sleep loss was most commonly attributed to infant itching (6/7), followed by worry (4/7). CONCLUSION: Infantile AD severity was associated with worse sleep outcomes for both mothers and infants. We propose that maternal and infantile sleep quality and quantity can be improved by reducing AD severity through adherence to topical treatments.
