One-Day Peer-Delivered Cognitive Behavioral Therapy-Based Workshops for Postpartum Depression: A Randomized Controlled Trial.

INTRODUCTION: Myriad treatment barriers prevent birthing parents with postpartum depression (PPD) from receiving timely treatment. We aimed to determine whether a peer-delivered online 1-day cognitive behavioral therapy (CBT)-based workshop added to treatment as usual (TAU) improves PPD and its comorbidities and is more cost-effective than TAU alone. METHODS: This parallel-group, randomized controlled trial took place in Ontario, Canada (June 7, 2021, to February 18, 2022). Participants were ≥18 years old, had an infant ≤12 months old, and an Edinburgh Postnatal Depression Scale (EPDS) score ≥10. Participants were allocated to receive the workshop plus TAU (n = 202) or TAU and waitlisted to complete the workshop 12 weeks later (n = 203). The primary outcome was change in PPD (EPDS score) from enrollment to 12 weeks later. The secondary outcome was cost-effectiveness and tertiary outcomes included anxiety, social support, partner relationship quality, the mother-infant relationship, parenting stress, and infant temperament. RESULTS: Participants had a mean age of 32.3 years (SD = 4.30) and 65% were White. The workshop led to a significant reduction in EPDS scores (15.95-11.37; d = 0.92, p < 0. 01) and was associated with higher odds of exhibiting a clinically significant decrease in EPDS scores (OR = 2.03; 95% CI: 1.26-3.29). The workshop plus TAU was more cost-effective than TAU alone. It also led to improvements in postpartum anxiety, infant-focused anxiety, parenting stress, and infant temperament. CONCLUSIONS: Peer-delivered 1-day CBT-based workshops can improve PPD and are a potentially scalable low-intensity treatment that could help increase treatment access.

Public health nurse-delivered cognitive behavioral therapy for postpartum depression: Assessing the effects of maternal treatment on infant emotion regulation.

The effects of maternal postpartum depression (PPD) on offspring emotion regulation (ER) are particularly deleterious as difficulties with ER predict an increased risk of psychopathology. This study examined the impact of maternal participation in a public health nurse (PHN)-delivered group cognitive behavioral therapy (CBT) intervention on infant ER. Mothers/birthing parents were ≥ 18 years old with an Edinburgh Postnatal Depression Scale (EPDS) score ≥ 10, and infants were < 12 months. Between 2017 and 2020, 141 mother-infant dyads were randomized to experimental or control groups. Infant ER was measured at baseline (T1) and nine weeks later (T2) using two neurophysiological measures (frontal alpha asymmetry (FAA) and high-frequency heart rate variability (HF-HRV)), and informant-report of infant temperament. Mothers were a mean of 30.8 years old (SD = 4.7), 92.3% were married/ common-law, and infants were a mean of 5.4 months old (SD = 2.9) and 52.1% were male. A statistically significant group-by-time interaction was found to predict change in HF-HRV between T1 and T2 (F(1,68.3) = 4.04, p = .04), but no significant interaction predicted change in FAA or temperament. Results suggest that PHN-delivered group CBT for PPD may lead to adaptive changes in a neurophysiological marker of infant ER, highlighting the importance of early maternal intervention.

Healthcare utilization before and during the COVID-19 pandemic among mothers and birthing parents with elevated levels of postpartum depression symptoms.

Little is known about the healthcare utilization of mothers and birthing parents experiencing elevated levels of symptoms of postpartum depression (PPD), particularly during the COVID-19 pandemic. This study examined how healthcare utilization changed in these individuals during COVID-19. Individuals living in Ontario, Canada, with Edinburgh Postnatal Depression Scale Scores ≥ 10 were recruited into two separate randomized controlled trials of a 1-day intervention for PPD before (pre-COVID-19, n = 441) and during the pandemic (COVID-19, n = 287). Participants in both samples completed the same health resource use questionnaire, self-reporting the number of virtual and/or in-person visits to specific healthcare services over the three months preceding their treatment intervention. Use of medications, mental health care, primary care, hospital-based care, allied health care, and overall healthcare utilization were compared between the pre-COVID-19 and COVID-19 groups. While participants had higher levels of PPD symptoms during COVID-19, differences were not seen in the use of specific categories of care (e.g. mental health and primary care). However, before and after statistically adjusting for covariates, overall healthcare utilization decreased from an average of 9.5 visits prior to COVID-19 to 6.9 during COVID-19 (p < .001), a change that was at least partly contributed to by reductions in visits to allied health professionals (e.g. dentists and physiotherapists). Overall healthcare utilization decreased by 27 % in mothers and birthing parents seeking treatment for elevated levels of PPD symptoms during the COVID-19 pandemic in Ontario, Canada - despite higher levels of PPD symptoms - highlighting the need to support and address barriers to postpartum care.

In-person 1-day cognitive behavioral therapy-based workshops for postpartum depression: a randomized controlled trial.

BACKGROUND: Postpartum depression (PPD) affects up to one in five mothers and birthing parents, yet as few as 10% access evidence-based treatment. One-day cognitive behavioral therapy (CBT)-based workshops for PPD have the potential to reach large numbers of sufferers and be integrated into stepped models of care. METHODS: This randomized controlled trial of 461 mothers and birthing parents in Ontario, Canada with Edinburgh Postnatal Depression Scale (EPDS) scores ⩾10, age ⩾18 years, and an infant <12 months of age compared the effects of a 1-day CBT-based workshop plus treatment as usual (TAU; i.e. care from any provider(s) they wished) to TAU alone at 12-weeks post-intervention on PPD, anxiety, the mother-infant relationship, offspring behavior, health-related quality of life, and cost-effectiveness. Data were collected via REDCap. RESULTS: Workshops led to meaningful reductions in EPDS scores (m = 15.77 to 11.22; b = -4.6, p < 0.01) and were associated with three times higher odds of a clinically significant decrease in PPD [odds ratio (OR) 3.00, 95% confidence interval (CI) 1.93-4.67]. Anxiety also decreased and participants had three times the odds of clinically significant improvement (OR 3.20, 95% CI 2.03-5.04). Participants reported improvements in mother-infant bonding, infant-focused rejection and anger, and effortful control in their toddlers. The workshop plus TAU achieved similar quality-adjusted life-years at lower costs than TAU alone. CONCLUSIONS: One-day CBT-based workshops for PPD can lead to improvements in depression, anxiety, and the mother-infant relationship and are cost-saving. This intervention could represent a perinatal-specific option that can treat larger numbers of individuals and be integrated into stepped care approaches at reasonable cost.

Online peer-delivered group cognitive-behavioral therapy for postpartum depression: A randomized controlled trial.

BACKGROUND: Postpartum depression (PPD) affects up to one in five mothers and birthing parents, yet just 10% receive evidence-based care. This randomized controlled trial aimed to determine if a synchronous online 9-week group cognitive-behavioral therapy (CBT) intervention delivered by mothers who have recovered from postpartum depression (i.e., peers) could effectively improve PPD and its comorbidities. METHODS: Participants (n = 183) in this study lived in Ontario, Canada, were ≥18 years-old, had an infant <12 months, were fluent in English, and scored ≥10 on the Edinburgh Postnatal Depression Scale (EPDS). They were randomized to experimental (received intervention plus treatment as usual (TAU)) or waitlist control (TAU plus the intervention after a 9-week wait) groups. Depression, anxiety, social support, mother-infant bonding, and infant temperament were assessed at baseline and 9 weeks later. Outcomes were assessed in the experimental group 3 months post-intervention to assess stability. RESULTS: Statistically significant reductions were observed in EPDS (B = 5.99; p < 0.001; d = 1.32) and Generalized Anxiety Disorder Questionnaire-7 scores (B = 5.94; p < 0.001; d = 1.22), improvements that remained stable 3 months post-intervention in the experimental group. Maternal social support (p = 0.02; d = 0.40), infant-focused anxiety (p = 0.02; d = 0.54), and infant negative emotionality (p < 0.01; d = 0.23) also improved post-intervention and remained stable 3 months later. CONCLUSION: Online peer-delivered group CBT for PPD can effectively treat PPD and anxiety, and improve social support, infant-focused anxiety, and negative emotionality in infants. This intervention could provide the means to increase access to treatment for those experiencing PPD and improve outcomes for mothers, birthing parents, and families.

Associations between maternal postpartum depression and infant temperament in treatment-seeking mothers prior to and during the COVID-19 pandemic.

It remains unclear how the COVID-19 pandemic has affected the mother-infant relationship and associations between maternal postpartum depression (PPD) and offspring temperament. This study examined the impact of the pandemic on these links and how maternal ratings of the mother-infant relationship mediated associations between PPD and infant temperament in a sample of treatment-seeking mothers in Ontario, Canada before and during the COVID-19 pandemic. Mothers with infants <12 months of age and Edinburgh Postnatal Depression Scale scores ≥10 enrolled in two separate randomized controlled trials of 1-day cognitive behavioral therapy-based workshops for PPD conducted before COVID-19 (n = 392) and during the pandemic (n = 403). Mothers reported on depressive symptomatology, infant temperament, and the mother-infant relationship. Maternal PPD was associated with more infant negative affectivity and mother-infant relationship difficulties. While associations between PPD and infant-focused anxiety were stronger during COVID-19, the pandemic did not otherwise affect associations between PPD and infant temperament. Mediation analyses suggested that aspects of the mother-infant relationship mediated associations between PPD and infant negative affectivity. Findings highlight the importance of detecting PPD and intervening to potentially improve outcomes for mothers and their children.

Dynamic changes in postnatal growth predict adolescent mental health problems in survivors of extremely low birth weight (ELBW).

Although individuals born at extremely low birth weight (ELBW; ≤1000 g) are known to be at greater risk for mental health problems than individuals born at normal birth weight (NBW; ≥2500 g), contributions of postnatal growth to these relations have not been fully explored. We compared individual differences in the Ponderal Index [(PI; weight(kg)/height(m3)] and head circumference (HC) in predicting internalizing and externalizing behaviors in childhood and adolescence in a cohort of ELBW survivors (N = 137) prospectively followed since birth. Baseline models indicated that infants who were born thinner or with smaller HC showed greater PI or HC growth in the first 3 years. Latent difference score (LDS) models showed that compensatory HC growth in the first year (ΔHC = 20.72 cm), controlled for birth HC, predicted ADHD behaviors in adolescence in those born with smaller HC. LDS models also indicated that the PI increased within the first year (ΔPI = 1.568) but decreased overall between birth and age 3 years (net ΔPI = -4.597). Modeling further showed that larger increases in the PI in the first year and smaller net decreases over 3 years predicted more internalizing behaviors in adolescence. These findings suggest early growth patterns prioritizing weight over height may have negative effects on later mental health in ELBW survivors, consistent with developmental programming theories.

Frontal EEG asymmetry moderates the relation between borderline personality disorder features and feelings of social rejection in adolescents.

Although associations among borderline personality disorder (BPD), social rejection, and frontal EEG alpha asymmetry scores (FAA, a neural correlate of emotion regulation and approach-withdrawal motivations) have been explored in different studies, relatively little work has examined these relations during adolescence in the same study. We examined whether FAA moderated the relation between BPD features and rejection sensitivity following a validated social exclusion paradigm, Cyberball. A mixed, clinical-community sample of 64 adolescents (females = 62.5%; Mage = 14.45 years; SD = 1.6; range = 11-17 years) completed psychodiagnostic interviews and a self-report measure of BPD (Time 1). Approximately two weeks later (Time 2), participants completed a resting EEG recording followed by Cyberball. FAA moderated the relation between BPD features and overall feelings of rejection following Cyberball: individuals with greater relative left FAA had the highest and lowest feelings of social rejection depending on whether they had high and low BPD feature scores, respectively. Results remained after controlling for age, sex, gender, depression, and BPD diagnosis. These results suggest that FAA may moderate the relation between BPD features and social rejection, and that left frontal brain activity at rest may be differentially associated with those feelings in BPD. Findings are discussed in terms of the link between left frontal brain activity in the regulation and dysregulation of social approach behaviors, characteristic of BPD.

Maternal Hyperglycemia in Pregnancy and Offspring Internalizing and Externalizing Behaviors.

OBJECTIVE: To examine the associations between exposure to gestational diabetes mellitus (GDM) and maternal glycemic markers during pregnancy and offspring behaviors at 3 and 5 years. We hypothesized that exposure to maternal hyperglycemia would be associated with more behavioral problems in offspring. METHODS: We included 548 mother-child pairs from the prospective pre-birth Gen3G cohort (Canada). Glycemic markers were measured during a 75 g oral glucose tolerance test (OGTT) in the second trimester of pregnancy. Based on OGTT, we classified 59 women (10.8%) as having GDM according to international diagnostic criteria. Mothers reported offspring behavior using the Strengths and Difficulties Questionnaire (SDQ) at 3 and 5 years, and the Child Behavior Checklist (CBCL) at 5 years. We used linear mixed models and multivariate regression to assess the associations between GDM or glycemic markers and children's behavior, adjusted for child sex and age, and maternal demographic factors, body mass index and family history of diabetes. RESULTS: Exposure to GDM was associated with higher SDQ externalizing scores at 3 and 5 years [B = 1.12, 95% CI (0.14, 2.10)] in fully adjusted linear mixed models. These results were supported by the CBCL at 5 years. Higher levels of maternal glucose at 1 h and 2 h during OGTT were associated with greater SDQ externalizing scores. Fasting glucose levels were not associated with child behavior scores. We did not observe associations between glycemic markers and internalizing behaviors. CONCLUSIONS: Exposure to higher levels of maternal glycemia during pregnancy was associated with more externalizing behaviors in children at 3 and 5 years.

What is already known on this subject? Prenatal exposure to gestational diabetes mellitus (GDM) has been linked to a higher risk of long-term consequences in offspring including metabolic problems and cognitive difficulties. However, prior studies examining associations between GDM and behavior in children reported mixed results. What this study adds? We reported associations between exposure to maternal GDM and post-OGTT hyperglycemia during pregnancy and greater levels of externalizing behaviors in children at 3 and 5 years of age. Our results underscore the importance of early detection of behavioral problems in children.

Mental Health Challenges Among First Nations Adolescents Living Off-Reserve in Ontario, Canada.

Limited data exist on the mental health challenges facing First Nations adolescents and the factors that modify these difficulties. The current study compared levels of common mental health challenges among 112 off-reserve First Nations and 3334 non-First Nations adolescents (12-17 years old) and examined the impact of maternal psychological distress on these mental health challenges. First Nations adolescents self-reported higher symptoms of conduct, oppositional-defiant, attention-deficit hyperactivity, major depressive, social phobia, generalized anxiety, and separation anxiety disorders and all associations remained statistically significant after adjusting for covariates. Moderation analyses found that increasing levels of maternal distress were associated more strongly with symptoms of oppositional defiant, attention-deficit hyperactivity, major depressive, and generalized anxiety disorders in First Nations adolescents. Future work aimed at improving the mental health of First Nations youth that focus on supporting these adolescents, and their mothers in particular, could result in substantial benefits.

Fidelity Assessment of Peer-Delivered Cognitive-Behavioral Therapy for Postpartum Depression.

OBJECTIVE: Fidelity assessment of peer-administered interventions (PAIs) by expert therapists can be costly and limit scalability. This study's objective was to determine whether peer facilitators could assess the fidelity of peer-delivered group cognitive-behavioral therapy (CBT) for postpartum depression as effectively as an expert psychiatrist or a trained graduate student. METHODS: Intervention adherence and competence were assessed by three peers (N=9 sessions) and by one expert psychiatrist and one graduate student (N=18 sessions). Interrater reliability was assessed with intraclass correlation coefficients (ICCs). RESULTS: ICCs were good to excellent (0.88-0.98) for adherence and competence ratings among the three types of raters (psychiatrist vs. peers, psychiatrist vs. student, and student vs. peers). CONCLUSIONS: Trained peers may be able to reliably rate the fidelity of a PAI for postpartum depression. This preliminary study represents the first step toward peer-led feedback as an alternative to expert-led supervision of peer-delivered group CBT for postpartum depression.

Transacting brains: testing an actor-partner model of frontal EEG activity in mother-infant dyads.

Studies have long observed the bidirectional nature of mother-infant relationships. While behavioral studies have shown that mothers high in social avoidance tendencies can influence the development of these traits in their offspring, the neurophysiological mechanisms underlying this phenomenon, and the role that the infants play, are not well understood. Here we acquired frontal electroencephalogram asymmetry (FA) data simultaneously in 40 mother-infant dyads (Mage mother = 31.6 years; Mage infant = 9 months). Using an actor-partner interdependence model, we examined whether mother (or infant) resting-state FA predicted infant (or mother) FA during two subsequent emotion-eliciting conditions (happy and fear). Maternal social approach versus avoidance traits were assessed as moderators to examine the impact of maternal characteristics on these mother-infant FA relations. In dyads led by mothers with high social avoidance/low social approach characteristics, maternal resting-state FA predicted infant FA during both emotion-eliciting conditions. We did not observe any effects of infant FA on mothers. Therefore, we speculate that individual differences in FA patterns might be a putative brain mechanism through which socially avoidant mothers transfer affective/behavioral information to their infants.

DNA methylation profiles in adults born at extremely low birth weight.

Effects of stresses associated with extremely preterm birth may be biologically "recorded" in the genomes of individuals born preterm via changes in DNA methylation (DNAm) patterns. Genome-wide DNAm profiles were examined in buccal epithelial cells from 45 adults born at extremely low birth weight (ELBW; ≤1000 g) in the oldest known cohort of prospectively followed ELBW survivors (Mage = 32.35 years, 17 male), and 47 normal birth weight (NBW; ≥2500 g) control adults (Mage = 32.43 years, 20 male). Sex differences in DNAm profiles were found in both birth weight groups, but they were greatly enhanced in the ELBW group (77,895 loci) versus the NBW group (3,424 loci), suggesting synergistic effects of extreme prenatal adversity and sex on adult DNAm profiles. In men, DNAm profiles differed by birth weight group at 1,354 loci on 694 unique genes. Only two loci on two genes distinguished between ELBW and NBW women. Gene ontology (GO) and network analyses indicated that loci differentiating between ELBW and NBW men were abundant in genes within biological pathways related to neuronal development, synaptic transportation, metabolic regulation, and cellular regulation. Findings suggest increased sensitivity of males to long-term epigenetic effects of extremely preterm birth. Group differences are discussed in relation to particular gene functions.

Public Health Nurse-delivered Group Cognitive Behavioural Therapy for Postpartum Depression: A Randomized Controlled Trial.

OBJECTIVES: To examine the effectiveness of group cognitive behavioural therapy (CBT) for postpartum depression (PPD) delivered by public health nurses with little to no previous psychiatric training at improving depression, worry, social support and the mother-infant relationship. METHODS: Mothers (n = 141) living in Ontario, Canada with Edinburgh Postnatal Depression Scale Scores ≥10 and an infant <12 months of age were randomized to receive nine weekly 2-h sessions of in-person group CBT for PPD delivered by two public health nurses plus treatment as usual (TAU; experimental group) or TAU alone (control group). Primary outcomes were change in EPDS score and current major depressive disorder (Mini International Neuropsychiatric Interview) assessed immediately post-treatment (T2). Secondary outcomes included maternal worry, social support, and quality of the mother-infant relationship. All outcomes were assessed again six months post-treatment (T3). RESULTS: Participants in the experimental group had statistically significantly greater reductions in PPD symptoms immediately post-treatment (T2) (B = -5.35, p < 0.01), were more likely to manifest a clinically significant improvement in EPDS scores (≥4 points; OR = 3.44, 95%CI: 1.49-7.94), and no longer have symptoms consistent with current MDD (OR = 5.31, 95% CI: 1.78-15.83). Six months post-treatment (T3), experimental group participants had higher odds of clinically significant PPD improvement (OR = 5.10, 95%CI: 1.89-13.78), while 25% of the experimental group and 70% of remaining control group participants reported current MDD (p < 0.01). Statistically significant improvements in worry and the mother-infant relationship were also observed, decreases maintained at six months post-treatment. CONCLUSIONS: Public health nurses with little to no previous psychiatric training can be trained to deliver effective group CBT for PPD to improve depression, worry, and the mother-infant relationship. Task shifting PPD treatment with group CBT to public health nurses could improve treatment uptake and lead to better outcomes for mothers, families, and the healthcare system.(Trial Registration NCT03039530).

Prevalence and Correlates of Physical-mental Multimorbidity in Outpatient Children From a Pediatric Hospital in Canada.

OBJECTIVE: The aim of this study was to estimate the six-month prevalence of mental illness in children with chronic physical illness (multimorbidity), examine agreement between parent and child reports of multimorbidity, and identify factors associated with child multimorbidity. METHOD: The sample included 263 children aged 2-16 years with a physician-diagnosed chronic physical illness recruited from the outpatient clinics at a pediatric hospital. Children were categorized by physical illness according to the International Statistical Classification of Diseases and Related Health Problems (ICD)-10. Parent and child-reported six-month mental illness was based on the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID). RESULTS: Overall, 101 (38%) of children had a parent-reported mental illness; 29 (25%) children self-reported mental illness. There were no differences in prevalence across ICD-10 classifications. Parent-child agreement on the MINI-KID was low (κ = 0.18), ranging from κ = 0.24 for specific phobia to κ = 0.03 for attention-deficit hyperactivity. From logistic regression modeling (odds ratio [OR] and 95% confidence interval), factors associated with multimorbidity were: child age (OR = 1.16 [1.04, 1.31]), male (OR = 3.76 [1.54, 9.22]), ≥$90,000 household income (OR = 2.57 [1.08, 6.22]), parental symptoms of depression (OR = 1.09 [1.03, 1.14]), and child disability (OR = 1.21 [1.13, 1.30]). Similar results were obtained when modeling number of mental illnesses. CONCLUSIONS: Findings suggest that six-month multimorbidity is common and similar across different physical illnesses. Level of disability is a robust, potentially modifiable correlate of multimorbidity that can be assessed routinely by health professionals in the pediatric setting to initiate early mental health intervention to reduce the incidence of multimorbidity in children.

Young mothers' use of and experiences with mental health care services in Ontario, Canada: a qualitative descriptive study.

BACKGROUND: Despite the high prevalence of mental health issues among young mothers, their subsequent needs for mental health care support does not correlate with their access and use of services. The purpose of this study, grounded in the experiences of young mothers living in Ontario, Canada, was to describe their experiences of using mental health services during the perinatal period, and to identify the attributes of services and professionals that influenced their decision to engage with mental health services. METHODS: As the qualitative component of a sequential explanatory mixed methods study, the principles of qualitative description informed sampling, data collection, and analysis decisions. In-depth, semi-structured interviews were conducted with a purposeful sample of 29 young mothers (≤ 21 years) who met diagnostic criteria for at least one psychiatric disorder, and who were ≥ 2 months postpartum. Interview data were triangulated with data from ecomaps and a sub-set of demographic data for this purposeful sample from the survey conducted in the quantitative study component. Qualitative data were analyzed using both conventional content analysis and reflexive thematic analysis; the subset of survey data extracted for these 29 participants were analyzed using descriptive statistics. RESULTS: Young mothers identified the need to have at least one individual, either an informal social support or formal service provider who they could talk to about their mental health. Among participants deciding to seek professional mental health support, their hesitancy to access services was grounded in past negative experiences or fears of being judged, being medicated, not being seen as an active partner in care decisions or experiencing increased child protection involvement. Participants identified organizational and provider attributes of those delivering mental health care that they perceived influenced their use of or engagement with services. CONCLUSION: Organizations or health/social care professionals providing mental health services to young pregnant or parenting mothers are recommended to implement trauma-and violence-informed care. This approach prioritizes the emotional and physical safety of individuals within the care environment. Applying this lens in service delivery also aligns with the needs of young mothers, including that they are actively listened to, treated with respect, and genuinely engaged as active partners in making decisions about their care and treatment.

Long-term stability of frontal electroencephalogram alpha power and asymmetry at rest in adults born at extremely low or normal birth weight: A 10-year longitudinal study.

The idea that individual differences in resting frontal EEG alpha activity have "trait-like" features that are associated with stress vulnerabilities presumes that these physiological patterns should be stable across time. We know, however, relatively little regarding the very long-term (i.e., ≥10 years) stability of resting frontal EEG alpha power and asymmetry in typically or atypically developing populations. Here, we examined the long-term stability of regional electroencephalogram (EEG) alpha (8-13 Hz) power and asymmetry at rest across a decade in the oldest known prospectively followed cohort of extremely low birth weight (ELBW; <1000 g) adult survivors and normal birth weight (NBW; >2500 g) controls. Regional EEG was collected at rest from the left and right frontal (F3, F4) and parietal (P3, P4) scalp sites using a stretchable cap during baseline eyes-open and eyes-closed conditions in young adulthood (ages 21-25 years) and again in adulthood (ages 30-35 years). We found moderate stability in regional EEG absolute alpha spectral power measures across all scalp sites for each birth weight group between the young adulthood and adulthood assessments. As well, we found the frontal alpha asymmetry measure was stable, albeit weakly, between the two assessment periods only in the NBW group. However, parietal alpha asymmetry was weak-to-moderately stable for each birth weight group across the 10-year period. Findings are discussed in terms of their implications for understanding associations between individual differences in frontal and parietal brain activity at rest and long-term stress vulnerability in typical and atypical development.

Children's shyness and frontal electroencephalogram delta-beta correlation in the pediatric surgical setting.

The prospect of surgery is a unique psychologically threatening context for children, often leading to experiences of preoperative anxiety. Recent research suggests that individual differences in children's temperament may influence responses to the surgical setting. In the present study, we examined whether individual differences in shyness were related to differences in frontal electroencephalogram (EEG) delta-beta correlation, a proposed neural correlate of emotion regulation and dysregulation, among children anticipating surgery. Seventy-one children (36 boys, Mage  = 10.3 years, SDage  = 1.7 years) undergoing elective surgery self-reported on their own shyness, and their parents also reported on their child's shyness. Using a mobile, dry sensor EEG headband, frontal EEG measures were collected and self- and observer-reported measures of state anxiety were obtained at the children's preoperative visit (Time 1) and on the day of surgery (Time 2). A latent cluster analysis derived classes of low shy (n = 37) and high shy (n = 34) children using the child- and parent-reported shyness measures. We then compared the two classes on frontal EEG delta-beta correlation using between- and within-subjects analyses. Although children classified as high versus low in shyness had higher self- and observer-reported state anxiety across both time periods, frontal EEG delta-beta correlation increased from T1 to T2 only among low shy children using a between-subjects delta-beta correlation measure. We discuss the interpretation of a relatively higher delta-beta correlation as a correlate of emotion regulatory versus dysregulatory strategies for some children in a "real-world," surgical context.

Changes in infant emotion regulation following maternal cognitive behavioral therapy for postpartum depression.

BACKGROUND: Exposure to maternal postpartum depression (PPD) increases the risk for emotion regulatory and psychiatric problems in offspring. This study aimed to determine if maternal cognitive behavioral therapy (CBT) for PPD improves infant emotion regulatory capacity. METHODS: Participants were 40 infants of mothers with a primary diagnosis of major depressive disorder matched 1:1-40 healthy control infants of nondepressed mothers on infant age, sex, and socioeconomic status. Mothers with PPD received nine weeks of group CBT. Dyads were tested at two time points. Visit 1 occurred following the first CBT session (baseline visit for control infants). Visit 2 took place after CBT (nine weeks post-baseline for controls). At both visits, infant emotion regulation was assessed using resting-state frontal electroencephalography alpha asymmetry (FAA), heart rate variability (HRV), and maternal and partner ratings of orientation or regulation behaviors (infant behavior questionnaire-revised [short form]). Changes in maternal characteristics (depression, bonding, and emotion regulation) from pretreatment to posttreatment were examined to determine if they explained infant changes. RESULTS: At Visit 1, infants of women with PPD exhibited poorer emotion regulation relative to the healthy control infants. At Visit 2, following maternal PPD treatment, infants exhibited improved emotion regulation (shifted from right to left FAA [p = .01, d = 0.60], increased HRV [p = .003, d = 0.56], mother [p = .015, d = 0.29] and partner [p = .049, d = 0.35] reported orientation or regulation behaviors) such that they no longer differed from the healthy control infants. Changes in maternal characteristics did not appear to account for these changes. CONCLUSION: Treating PPD may promote adaptive changes in physiological and behavioral systems underlying infant emotion regulation.

Psychopathology in the Offspring of Indigenous Parents with Mental Health Challenges: A Systematic Review: Psychopathologie des descendants de parents autochtones ayant des problèmes de santé mentale: Une revue systématique.

OBJECTIVE: Parental psychopathology is a significant risk factor for mental health challenges in offspring, but the nature and magnitude of this link in Indigenous Peoples is not well understood. This systematic review examined the emotional and behavioral functioning of the offspring of Indigenous parents with mental health challenges. METHOD: We searched MEDLINE, EMBASE, PsycINFO, CINAHL, and Web of Science from their inceptions until April 2020. Studies were included if they included assessments of emotional, behavioral, or other psychological outcomes in the offspring of Indigenous parents with a mental health challenge. RESULTS: The 14 studies eligible for review were focused on parental substance misuse (n = 8), maternal internalizing (i.e., depression, anxiety) issues (n = 5), and poor overall parental mental health (n = 4). In 11 studies, parental substance misuse, depression, and/or overall mental health challenges were associated with 2 to 4 times the odds of offspring externalizing and internalizing behaviors as compared to offspring of Indigenous parents without mental health challenges. CONCLUSION: The findings suggest higher risks of mental health challenges among offspring of Indigenous parents with psychiatric difficulties than among Indigenous children of parents without similar difficulties. Knowledge of these phenomena would be improved by the use of larger, more representative samples, culturally appropriate measures, and the engagement of Indigenous communities. Future studies should be focused on both risk and resilience mechanisms so that cycles of transmission can be interrupted and resources aimed at detection, prevention, and treatment optimally allocated.
