Early Crying, Sleeping, and Feeding Problems and Trajectories of Attention Problems From Childhood to Adulthood

Regulatory problems and associated factors among infants in Arba Minch health and demographic surveillance system sites, southern Ethiopia

INTRODUCTION

Infant regulatory problems are a common source of concern for parents, and they increase the risk of impaired infant-caregiver bonding. Despite their impact, they are often overlooked in Ethiopia. Hence, this study aimed to determine the prevalence and associated factors of infant regulatory problems in Arba Minch Health and Demographic Surveillance System sites in southern Ethiopia.

METHODS

A community-based cross-sectional study was conducted among 451 mother-infant pairs from February 15 to March 15, 2022. Regulatory problems were assessed using diagnostic interviews for regulatory problems. The data was collected using an open data kit Android application and analyzed with Stata version 17.0. Bivariable and multivariable logistic regression analyses were computed to identify factors associated with each infant regulatory problem. Statistical significance was declared at a p-value < 0.05.

RESULTS

In this study, four hundred forty-nine mother-infant pairs were involved, with a response rate of 99.5%. The prevalence of excessive crying, feeding problems, and sleeping difficulties was 14.03% [95% CI: 10.95, 17.59], 20.04% [95% CI: 16.44, 24.05], and 13.59% [95% CI: 10.55, 17.11], respectively. Attending primary education (AOR: 2.54, 95% CI: 1.22, 5.32), high perceived social support (AOR: 0.32, 95% CI: 0.12, 0.89), feeding problems (AOR: 5.0, 95% CI: 2.65, 9.45), and depression, anxiety, and stress (DAS) symptoms (AOR: 2.67, 95% CI: 1.19, 5.98) were associated with excessive crying. In addition, a family size of above five (AOR: 1.82, 95% CI: 1.03, 3.22), excessive crying (AOR: 3.76, 95% CI: 1.85, 7.65), sleeping problems (AOR: 2.29, 95% CI: 1.13, 4.65), comorbid DAS symptoms (AOR: 3.42, 95% CI: 1.64, 7.11), alcohol abuse (AOR: 1.89, 95% CI: 1.04, 3.42), and late initiation of complementary feeding (AOR: 2.67, 95% CI: 1.22, 5.88) were associated with feeding problems. Furthermore, attending primary education (AOR: 2.35, 95% CI: 1.16, 4.77), feeding problems (AOR: 3.47, 95% CI: 1.86, 6.48), and comorbid DAS symptoms (AOR: 3.23, 95% CI: 1.53, 6.84) were associated with sleeping problems.

CONCLUSIONS

Approximately one-third of infants encountered at least one regulatory problem. Level of education, perceived social support, feeding problems, and DAS symptoms were associated with excessive crying. Large family sizes, excessive crying, sleeping problems, comorbid DAS symptoms, alcohol abuse and, late initiation of complementary feeding increase the likelihood of feeding problems. Moreover, attending primary education, feeding problems, and comorbid DAS symptoms increase the odds of sleeping problems. Continuous guidance and support on infant soothing techniques, cognitive and behavioral therapy, and counselling on appropriate coping strategies for postpartum women are imperative to reduce the burden of infant regulatory problems.

Early childhood multiple or persistent regulatory problems and diurnal salivary cortisol in young adulthood

BACKGROUND

Early childhood multiple or persistent regulatory problems (RPs; crying, sleeping, or feeding problems) have been associated with a risk of behavioural problems in young adulthood. It has been suggested that this may be due to the possible influence of early RPs on the functioning of the hypothalamic-pituitary-adrenal (HPA) axis. However, associations between early RPs and HPA-axis activity in young adulthood remain unexplored. Thus, the aim of the current study was to investigate whether early childhood multiple or persistent RPs are associated with diurnal salivary cortisol in young adulthood.

METHODS

At the ages of 5, 20 and 56 months, RPs of 308 children from the Arvo Ylppö Longitudinal Study were assessed via standardized parental interviews and neurological assessments. Multiple RPs were defined as two or three RPs at the age of 5 months and persistent RPs as at least one RP at 5, 20 and 56 months. At the mean age of 25.4 years (SD= 0.6), the participants donated saliva samples for cortisol at awakening, 15 and 30 min thereafter, 10:30 am, at noon, 5:30 pm, and at bedtime during one day. We used mixed model regressions, and generalized linear models for testing the associations, controlling for important covariates.

RESULTS

Of the 308 children, 61 (19.8%) had multiple or persistent RPs in early childhood: 38 had multiple, and 27 had persistent RPs. Persistent RPs were associated with significantly higher cortisol peak and output in the waking period, and cortisol awakening response. On the other hand, multiple RPs were not associated with salivary cortisol.

CONCLUSION

Children displaying persistent RPs throughout early childhood show, over two decades later, increased HPA axis activity in response to awakening stress. This may be one physiological mechanism linking early childhood RPs to adulthood behavioural outcomes.

App-based intervention for parents of children with crying, sleeping, and feeding problems: Usability, usefulness and implications for improvement

Background

There is a lack of evidence-based app guidance for parents of children with crying, sleeping, and feeding problems who are often highly burdened and not likely to seek professional help. A new psychoeducational app for parents providing scientifically sound information via text and videos, a diary function, selfcare strategies, a chat forum and a regional directory of specialized counseling centers may serve as a low-threshold intervention for this target group.

Objective

We investigated how parents perceived the app in terms of the following: (1) overall impression and usability, (2) feedback on specific app functions regarding usefulness and (3) possible future improvements.

Methods

Our clinical sample of N = 137 parents of children aged from 0 to 24 months was recruited from a cry baby outpatient clinic in Southern Germany between 2019 and 2022. A convergent parallel mixed methods design was used to collect and analyse cross-sectional data on app evaluation. After app use within the framework of a clinical trial, parents filled in an app evaluation questionnaire.

Results

Most participants used the app at least once a week (86, 62.8 %) over an average period of 19.06 days (SD = 15.00). Participants rated overall impression and usability as good, and the informational texts, expert videos and regional register of counseling centers as appealing and useful. The diary function and chat forum were found to be helpful in theory, but improvements in implementation were requested, such as a timer function for the diary entry. Regarding future functionality, parents posed several suggestions such as the option to contact counseling centers directly via app, and the inclusion of the profile of their partners.

Conclusions

Positive ratings of overall impression, usability, and specific app functions are important prerequisites for the app to be effective. App-based guidance for this target group should include easy-to-use information. The app is intended to serve as a secondary preventive low-threshold offer and to complement professional counseling.

Burden of mental, behavioral, and neurodevelopmental disorders in the Finnish most preterm children: a national register study

Etiologies and the whole picture in childhood mental, behavioral, and neurodevelopmental disorders related to gestational age are unclear. This study included all Finnish children (N = 341,632) born between January 1, 2001, and December 31, 2006, whose data including their mothers (N = 241,284) were collected from national registers. Children with unclear gestational age (GA) (N = 1245), severe congenital malformations (N = 11,746), and moderate/severe/undefined cognitive impairment (N = 1140), and those who died during the perinatal period (N = 599) were excluded. The main outcome was the prevalence of mental and behavioral disorders (International Classification of Disorders) at 0 - 12 years of age in association with GA, adjusted for gender and prenatal variables. Out of all included (N = 326,902) children 16.6% (N = 54,270) were diagnosed to have any mental health disorder at 0 - 12 years. Adjusted Odd Ratio (OR) were for any disorder in preterm (< 37 weeks) 1.37 [1.28 - 1.46] and 4.03 [3.08 - 5.26] in extreme preterm (≤ 28 weeks) versus term born children, p < 0.05. The lower the GA at birth, the higher the risk for multiple disorders and earlier onset of disorder, p < 0.05. Adjusted ORs were for male/female 1.94 [1.90 - 1.99], maternal mental health disorder (yes/not) 1.99 [1.92 - 2.07], and smoking during pregnancy (yes/not) 1.58 [1.54 - 1.62], and these risks were more common in preterm versus term born children (p < 0.05). Extreme early birth was a strong risk factor per se for any or multiple and early shown mental health disorders. Other risk factors for mental health accumulated to preterm children.

Systematic Review and Meta-Analysis: Early Irritability as a Transdiagnostic Neurodevelopmental Vulnerability to Later Mental Health Problems

OBJECTIVE

Irritability is a transdiagnostic indicator of child and adolescent internalizing and externalizing problems that is measurable from early life. The objective of this systematic review was to determine the strength of the association between irritability measured from 0 to 5 years and later internalizing and externalizing problems, to identify mediators and moderators of these relationships, and to explore whether the strength of the association varied according to irritability operationalization.

METHOD

Relevant studies published in peer-reviewed, English-language journals between the years 2000 and 2021 were sought from EMBASE, PsycINFO, MEDLINE, CINAHL, and ERIC. We synthesized studies that included a measure of irritability within the first 5 years of life and reported associations with later internalizing and/or externalizing problems. Methodological quality was assessed using the JBI-SUMARI Critical Appraisal Checklist.

RESULTS

Of 29,818 identified studies, 98 met inclusion criteria, with a total number of 932,229 participants. Meta-analysis was conducted on 70 studies (n = 831,913). Small, pooled associations were observed between infant irritability (0-12 months) and later internalizing (r = 0.14, 95% CI = 0.09, 0.20) and externalizing symptoms (r = 0.16, 95% CI = 0.11, 0.21) symptoms. For toddler/preschool irritability (13-60 months), small-to-moderate pooled associations were observed for internalizing (r = 0.21, 95% CI = 0.14, 0.28) and externalizing (r = 0.24, 95% CI = 0.18, 0.29) symptoms. These associations were not moderated by the lag between irritability and outcome assessment, although the strength of the associations varied according to irritability operationalization.

CONCLUSION

Early irritability is a consistent transdiagnostic predictor of internalizing and externalizing symptoms in childhood and adolescence. More work is required to understand how to accurately characterize irritability across this developmental period, and to understand mechanisms underlying the relationship between early irritability and later mental health problems.

Eating behaviour in Swiss preschool children-Validation of a German and a French version of the Children's Eating Behaviour Questionnaire (CEBQ)

Young children's eating behavior is crucial for any further development of healthy eating. Early eating behavior are often assessed through parental report. The Children's Eating Behaviour Questionnaire (CEBQ) is a widely used parental questionnaire that has been validated in families of different gender, age and cultural background. Research has shown that the 8-factor structure has some inconsistencies and sample characteristics such as age, gender, and culture can influence the results. To which extent such sample characteristics might influence results within a multi-lingual culture has not been investigated so far. Therefore, the aim of the study was to evaluate the factor structure of the CEBQ among 511 preschool children of the French and German parts of Switzerland, aged 2 to 6 years (Mean 3.85 years; SD 0.69). Confirmatory Factor Analysis showed a modified structure of the original questionnaire, with a 7-factor structure providing a reasonable fit to the data (TLI = 0.954, CFI = 0.952, RMSEA = 0.063 and SRMR = 0.067). The subscale 'Desire to drink' was removed, and a few items moved to other subscales as they loaded higher on a different subscale compared to the original model. Reliabilities based on the coefficient omega were acceptable to satisfying across the seven factors, ranging from 0.66 to 0.90. There were no significant gender or age differences, but French speaking children showed higher levels of 'Satiety responsiveness' and lower 'Enjoyment of food' than German speaking children. Yet, these effects were small. The German and French CEBQ are valid and reliable versions of the original CEBQ and can be used in a multicultural context.

Infant sleep predicts trajectories of social attention and later autism traits

BACKGROUND

Children with neurodevelopmental disorders including autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) often experience sleep disturbances, but little is known about when these sleep differences emerge and how they relate to later development.

METHODS

We used a prospective longitudinal design in infants with a family history of ASD and/or ADHD to examine infant sleep and its relation to trajectories of attention and later neurodevelopmental disorders. We formed factors of Day and Night Sleep from parent-reported measures (including day/night sleep duration, number of naps in the day, frequency of night awakenings and sleep onset problems). We examined sleep in 164 infants at 5-, 10- and 14-months with/without a first-degree relative with ASD and/or ADHD who underwent a consensus clinical assessment for ASD at age 3.

RESULTS

By 14-months, infants with a first-degree relative with ASD (but not ADHD) showed lower Night Sleep scores than infants with no family history of ASD; lower Night Sleep scores in infancy were also associated with a later ASD diagnosis, decreased cognitive ability, increased ASD symptomatology at 3-years, and developing social attention (e.g., looking to faces). We found no such effects with Day Sleep.

CONCLUSIONS

Sleep disturbances may be apparent at night from 14-months in infants with a family history of ASD and also those with later ASD, but were not associated with a family history of ADHD. Infant sleep disturbances were also linked to later dimensional variation in cognitive and social skills across the cohort. Night Sleep and Social Attention were interrelated over the first 2 years of life, suggesting that this may be one mechanism through which sleep quality influences neurodevelopment. Interventions targeted towards supporting families with their infant's sleep problems may be useful in this population.

The longitudinal association of combined regulatory problems in infancy and mental health outcome in early childhood: a systematic review

Co-occurring regulatory problems in infancy, RPs, including excessive crying, feeding-eating and sleeping, have been found associated with mental health problems in school ages. Still, an overview is needed on trajectories of co-occurring or combined RPs, and mental health problems in early childhood. The aim of this review is to systematically review the literature on longitudinal community-based studies of combined RPs measuring mental health outcomes in early childhood. Following the PRISMA guideline, we systematically reviewed the literature published 2000-2020, in which combined RPs are assessed in infancy, and mental health is examined using standardised measures at ages 1-7 years. The search was performed in four databases MEDLINE, EMBASE, PsycINFO and Scopus. A protocol is published on PROSPERO. Based on 1978 screened articles, 42 papers were screened for eligibility, of which six were included, comprising data on two or more RPs investigated among a total of 20,675 children. Assessment of risk of bias in the studies showed overall good quality in five of the six papers. The literature reviewed suggests that combined RPs in infancy are early markers of mental health problems during early childhood, and highlights that community studies exploring the longitudinal associations of combined RP and mental health problems in preschool and early school age are still scarce. Overall, the review points to the need of research into preventive intervention targeting early manifestations of childhood dysregulation, such as RPs.

Family and developmental history of female versus male adolescents with ADHD: diagnosis-specific overlap, few gender/sex differences

Background

Gender and sex differences in the development of children and adolescents are commonly found in the psychiatric examination. Family and developmental history is an important part of the clinical diagnostic interview, the basic examination technique. Attention-deficit/hyperactivity disorder (ADHD) is associated with diagnosis-specific markers in family and development history. However, it is unclear to what extent ADHD-specific signs and narratives differ between females and males. The aim of this study was to assess and to compare the family and developmental history profiles of female versus male adolescents with ADHD.

Methods

Data were collected using the clinical diagnostic interview technique from parents of female and male patients diagnosed with ADHD (ICD-10  F90.0, F90.1 and F98.8) between the ages of 12 and 17  years (n = 92). The two groups were matched in pairs for sex, IQ and ICD-10 diagnosis (F90.0, F90.1 and F98.8). Interview data were operationalized in three categories: 0 - physiological marker, 1 - subclinical marker, 2 - clinical marker. The two groups were compared with two-way ANOVA.

Results

Information about female in comparison to male adolescents were reported in the parental interview with few differences.

Conclusion

Our study suggests that family and developmental history of the neurodevelopmental disorder ADHD is only poorly influenced by gender or sex.

Associations of crying, sleeping, and feeding problems in early childhood and perceived social support with emotional disorders in adulthood

BACKGROUND

Multiple or persistent crying, sleeping, or feeding problems in early childhood (regulatory problems) are associated with increased internalizing symptoms in adulthood. Unknown is whether early regulatory problems are associated with emotional disorders in adulthood, and what psychosocial factors may provide protection. We tested whether early childhood multiple or persistent regulatory problems are associated with a higher risk of (a) any mood and anxiety disorder in adulthood; (b) perceiving no social support in adulthood; and (c) whether social support provides protection from mood and anxiety disorders among participants who had multiple/persistent regulatory problems and those who never had regulatory problems.

METHODS

Data from two prospective longitudinal studies in Germany (n = 297) and Finland (n = 342) was included (N = 639). Regulatory problems were assessed at 5, 20, and 56 months with the same standardized parental interviews and neurological examinations. In adulthood (24-30 years), emotional disorders were assessed with diagnostic interviews and social support with questionnaires.

RESULTS

Children with multiple/persistent regulatory problems (n = 132) had a higher risk of any mood disorder (odds ratio (OR) = 1.81 [95% confidence interval = 1.01-3.23]) and of not having any social support from peers and friends (OR = 1.67 [1.07-2.58]) in adulthood than children who never had regulatory problems. Social support from peers and friends provided protection from mood disorders, but only among adults who never had regulatory problems (OR = 4.03 [2.16-7.94]; p = .039 for regulatory problems x social support interaction).

CONCLUSIONS

Children with multiple/persistent regulatory problems are at increased risk of mood disorders in young adulthood. Social support from peers and friends may, however, only provide protection from mood disorders in individuals who never had regulatory problems.

Research Review: A systematic review and meta-analysis of infant and toddler temperament as predictors of childhood attention-deficit/hyperactivity disorder

BACKGROUND

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder with onset as early as preschool and impairment across the lifespan. Temperament factors, specifically those that theoretically map onto ADHD symptoms, may be early markers of risk for developing later childhood ADHD that could be identifiable in infancy or toddlerhood. This meta-analysis examined the associations between these early temperamental factors and later symptoms and diagnosis of ADHD and mapped early temperament constructs onto the three ADHD symptom dimensions.

METHODS

A systemic review of the literature was conducted to identify prospective longitudinal studies that included theoretically relevant temperament constructs (sustained attention, activity level, inhibition, and negative emotionality) examined from birth to 36 months old and ADHD (symptoms or diagnosis) in preschool or childhood. The association between each temperament construct and ADHD outcomes was examined using pooled standardized estimates in meta-analyses.

RESULTS

Forty-eight articles (n = 112,716 infants/toddlers) prospectively examined temperament and the relation to childhood ADHD symptoms or diagnosis. Activity level (k = 18) in infancy and toddlerhood was moderately associated with childhood ADHD (r = .39, CI = 0.27, 0.51, p < .001). Moderate effect sizes were also observed for sustained attention (k = 9; r = -.28, CI = -0.42, -0.12, p < .001) and negative emotionality (k = 33; r = .25, CI = 0.16, 0.34, p < .001) with ADHD. The specificity of each temperament construct for later ADHD symptom dimensions was such that activity level and negative emotionality were predictive of all three symptom dimensions (i.e., inattention, hyperactivity/impulsivity, and combined), whereas sustained attention was only associated with combined symptoms.

CONCLUSIONS

Infant and toddler temperament is an early risk factor for the development of childhood ADHD that could be utilized for early intervention identification. Yet, this systematic review found that relatively few prospective longitudinal studies have examined sustained attention (k = 9) and inhibition (k = 15) in infancy and toddlerhood in relation to later ADHD highlighting the need for further research.

Effects of a Mobile-Based Intervention for Parents of Children With Crying, Sleeping, and Feeding Problems: Randomized Controlled Trial

BACKGROUND

Excessive crying, sleeping, and feeding problems in early childhood are major stressors that can result in parents feeling socially isolated and having low self-efficacy. Affected children are a risk group for being maltreated and developing emotional and behavioral problems. Thus, the development of an innovative and interactive psychoeducational app for parents of children with crying, sleeping, and feeding problems may provide low-threshold access to scientifically based information and reduce negative outcomes in parents and children.

OBJECTIVE

We aimed to investigate whether following the use of a newly developed psychoeducational app, the parents of children with crying, sleeping, or feeding problems experienced less parenting stress; gained more knowledge about crying, sleeping, and feeding problems; and perceived themselves as more self-effective and as better socially supported and whether their children's symptoms decreased more than those of the parents who did not use the app.

METHODS

Our clinical sample consisted of 136 parents of children (aged 0-24 months) who contacted a cry baby outpatient clinic in Bavaria (Southern Germany) for an initial consultation. Using a randomized controlled design, families were randomly allocated to either an intervention group (IG; 73/136, 53.7%) or a waitlist control group (WCG; 63/136, 46.3%) during the usual waiting time until consultation. The IG was given a psychoeducational app that included evidence-based information via text and videos, a child behavior diary function, a parent chat forum and experience report, tips on relaxation, an emergency plan, and a regional directory of specialized counseling centers. Outcome variables were assessed using validated questionnaires at baseline test and posttest. Both groups were compared at posttest regarding changes in parenting stress (primary outcome) and secondary outcomes, namely knowledge about crying, sleeping, and feeding problems; perceived self-efficacy; perceived social support; and child symptoms.

RESULTS

The mean individual study duration was 23.41 (SD 10.42) days. The IG reported significantly lower levels of parenting stress (mean 83.18, SD 19.94) after app use compared with the WCG (mean 87.46, SD 16.67; P=.03; Cohen d=0.23). Furthermore, parents in the IG reported a higher level of knowledge about crying, sleeping, and feeding (mean 62.91, SD 4.30) than those in the WCG (mean 61.15, SD 4.46; P<.001; Cohen d=0.38). No differences at posttest were found between groups in terms of parental efficacy (P=.34; Cohen d=0.05), perceived social support (P=.66; Cohen d=0.04), and child symptoms (P=.35; Cohen d=0.10).

CONCLUSIONS

This study provides initial evidence of the efficacy of a psychoeducational app for parents with child crying, sleeping, and feeding problems. By reducing parental stress and increasing knowledge of children's symptoms, the app has the potential to serve as an effective secondary preventive measure. Additional large-scale studies are needed to investigate long-term benefits.

Excessive Crying, Behavior Problems, and Amygdala Volume: A Study From Infancy to Adolescence

OBJECTIVE

Excessive crying in infancy has been associated with increased risk of later behavioral problems. To identify individuals at risk for behavioral problems and to understand the mechanisms underlying excessive crying and irritability in infancy, research into the neurobiology of excessive crying is needed. We examined whether excessive crying and irritability in infancy are associated with behavioral problems and amygdala volume among children and adolescents.

METHOD

This study included 4,751 singleton children from the prospective population-based Generation R Study cohort, born in the Netherlands in 2002 to 2006. Excessive crying (>3 hours on at least 1 day/wk) and irritability (Mother and Baby Scales questionnaire) were parent-rated at 3 months. Amygdala volume was measured at 10 years using magnetic resonance imaging, and internalizing and externalizing were parent-rated at 1.5, 3, 6, 10, and 14 years and self-rated at 14 years. Covariates included child age, sex, national origin, gestational age, and maternal age, psychopathology score, parity, education, relationship status, and family income.

RESULTS

Children who cried excessively in infancy had higher parent-rated internalizing (effect estimate = 0.20 SD-units, 95% CI = 0.14, 0.27) and externalizing (0.17 SD-units, 95% CI = 0.10, 0.24) throughout childhood (linear mixed models), and smaller amygdala volume at 10 years (-0.19 SD-units, 95% CI = -0.32, -0.06) (linear regression model). The pattern of associations for both behavioral problems and amygdala volume was similar for irritability.

CONCLUSION

Excessive crying and irritability in infancy may reflect an early vulnerability to behavioral problems and may be linked with neurobiological differences in the development of the amygdala.

The association of early regulatory problems with behavioral problems and cognitive functioning in adulthood: two cohorts in two countries

BACKGROUND

Regulatory problems (RPs; excessive crying, sleeping, or feeding difficulties) that co-occur (i.e., multiple) or are persistent have been associated with cognitive and behavioral problems in childhood. However, it remains unknown if multiple or persistent RPs are associated with cognitive and behavioral problems in adulthood.

METHODS

This large prospective longitudinal study (N = 759) was conducted in two cohorts in Germany (N = 342) and Finland (N = 417). RPs were assessed at 5, 20, and 56 months via the same standardized parental interviews and neurological examinations. In young adulthood, questionnaires were used to assess behavioral problems. Cognitive functioning was assessed with IQ tests. We examined the effects of multiple or persistent RPs on the outcomes via analysis of covariance tests and logistic regression controlled for the influence of cohort.

RESULTS

Of 163 participants with RPs, 89 had multiple and 77 had persistent RPs. Adults who had early multiple or persistent RPs (N = 151) reported more internalizing (p = .001), externalizing (p = .020), and total behavioral problems (p = .001), and, specifically, more depressive (p = .012), somatic (p = .005), avoidant personality (p < .001), and antisocial personality problems (p = .006) than those who never had RPs (N = 596). Participants with multiple or persistent RPs were more likely to receive any ADHD diagnoses (p = .017), particularly of hyperactive/impulsive subtype (p = .032). In contrast, there were no associations between multiple or persistent RPs and IQ scores in young adulthood.

CONCLUSIONS

The results indicate long-lasting associations between multiple or persistent RPs and behavioral problems. Thus, screening for early RPs could help to identify children who are at risk for later behavioral problems.

A single-arm pilot study: can a parental sleep intervention for sleep-disturbed young children in individual settings improve children's sleep, crying, eating, and parental distress in mothers and fathers?

Background

Early sleep problems co-occur with crying, eating problems, and parental distress. This study investigates the impact of a parent-focused intervention to improve child sleep with the following aims: (1) To assess the impact on child sleep (sleep onset latency, frequency and duration of nighttime awakenings, frequency of bed-sharing, and nighttime food intake, total nighttime sleep duration, and sleep efficiency), child crying (frequency of crying episodes, of unexplained and unsoothable crying and of crying out of defiance), child eating difficulties, and parental distress of mothers and fathers. (2) To assess the maintenance of any changes in these areas longitudinally, at 3-month, 6-month, and 12-month follow-ups. (3) To explore at the within-subjects level, how children’s sleep, crying, eating, and parental distress changed together across all study measurement points.

Methods

In this single-arm pilot study, the parents of 60 children participated in six individual sessions of a parent-focused multimodal age-adjusted cognitive-behavioral intervention to improve child sleep. Parents of 39 children (46% girls, age in months M = 22.41, SD = 12.43) completed pre- and at least one measure after the intervention. Sleep diary, questionnaire for crying, feeding, sleeping, and parental stress index (short-form) were assessed pre, post, three, six, and 12 months after the intervention.

Results

Significantly, sleep (decreased sleep onset latency, frequency, duration of nighttime awakenings, bed-sharing, nighttime food intake; increased total nighttime sleep duration, sleep efficiency), crying (reduced frequency of crying episodes, unexplained and unsoothable crying), and parental distress (reduced) changed, which remained partially stable over follow-up. The frequency of crying episodes decreased with fewer nighttime awakenings; morning crying with increased nighttime feeding; unexplained and unsoothable crying with higher sleep efficiency; crying due to defiance with more nighttime awakenings, sleep efficiency, and bed-sharing. Eating problems decreased with shorter night awakenings and time; maternal distress with fewer nighttime awakenings, paternal with less child’s nighttime feeding, unexplained and unsoothable crying, and time.

Conclusions

A parental sleep intervention for sleep-disturbed young children could be promising to reduce children’s sleep problems, crying, eating problems and parental distress. Future studies should consider more personal contact during the follow-up to reduce the drop-out rate and a randomized-controlled design.

Trial registration

The study was retrospectively registered at the German Clinical Trials Register (ID: DRKS00028578, registration date: 21.03.2022).

The interaction between infant negative emotionality and cognition predicts ADHD-related behaviors in toddlerhood

Attention-deficit/hyperactivity disorder (ADHD) is a highly prevalent disorder commonly identified in childhood. Affective and cognitive characteristics that are identifiable as early as infancy could be signals of risk for developing ADHD. Specifically, the interplay between emotionality and cognition may be important in predicting early symptoms of ADHD. This study examined the independent and interactive effects of infant negative emotionality and cognition on the development of inattention and hyperactivity/impulsivity in toddlerhood among infants at high and low familial likelihood for ADHD. Participants were 64 infants (M = 8.7, SD = 1.8) at high (n = 32) and low (n = 32) familial likelihood for ADHD, defined as at least one parent with ADHD or two parents without ADHD, respectively. Negative emotionality and cognition in infancy were assessed using the Infant Behavior Questionnaire and the Bayley's Scales of Infant and Toddler Development, and ADHD symptoms were assessed at toddler follow-up (M= 20.0, SD= 3.2) using the Child Behavior Checklist. Accounting for the quality of parent-child interaction, infants' negative emotionality (β = .033, p = .938) and cognition (β = .006, p = .884) did not independently predict toddlers' ADHD-related behaviors, but their interaction did (β = .110, p = .019). For infants with higher levels of cognition (>95th percentile), higher negative emotionality predicted more ADHD-related behaviorss. For infants with lower levels of cognition (<11th percentile), higher negative emotionality predicted fewer ADHD-related behaviors. There may be two affective-cognitive pathways to inattention and hyperactivity/impulsivity in toddlerhood. The combination of higher levels of negative emotionality and cognition may result in greater frustration when goals are blocked, resulting in the expression of dysregulated behaviors (i.e., ADHD symptoms). Alternatively, low levels of negative emotionality and cognition combined may lead to dysregulation that is primarily cognitive in nature (such as the inattention symptoms of ADHD). Investigating affective and cognitive processes simultaneously may be important for increasing understanding of the early signals of ADHD risk.

A cross-sectional investigation of psychosocial stress factors in German families with children aged 0-3 years during the COVID-19 pandemic: initial results of the CoronabaBY study

BACKGROUND

Psychosocial stress during the COVID-19 pandemic is increasing particularly in parents. Although being specifically vulnerable to negative environmental exposures, research on psychosocial stress factors in infants' and toddlers' families during the pandemic is so far sparse. The CoronabaBY study investigates the perceived pandemic burden, parenting stress and parent and child mental health problems in families with children aged 0-3 years in Bavaria, Southern Germany. Further, the relationships between these psychosocial stressors are examined and sociodemographic characteristics that may be predictive of these factors will be explored.

METHODS

Participants were cross-sectionally surveyed via smartphone app. Standardized questionnaires on perceived pandemic burden, parenting stress, parental symptoms of depression and anxiety, infants' crying, sleeping and feeding problems or toddlers' emotional and behavioral problems were applied.

RESULTS

N = 991 parents (M_age = 33.7 years, SD = 4.5; 93.7% mothers, 91.5% born in Germany) with infants (n = 554; M_age = 5.9 months, SD = 3.0) or toddlers (n = 435; M_age = 25.9 months, SD = 6.5) participated in the first half-year of 2021. Sixty-five percent of the parents perceived a high pandemic burden, 37.7% experienced parenting stress and 24.1% showed affective symptoms (anxiety: 30.1%, depression: 18.5%). Feeding problems, crying/ sleeping problems and multiple regulatory problems were found in 34.8%, 26.2% and 13.5% of the infants, respectively. Amongst toddlers, 8.5% showed noticeable behavior and emotional problems. Children`s mental health problems correlated moderately with parenting stress and parental affective symptoms and weakly with perceived pandemic burden. A lower financial status, higher parental education and increasing child age were significant but weak predictors for higher parenting stress, affective symptoms and higher psychological problems in children.

CONCLUSIONS

A majority of the surveyed families with infants and toddlers experience the pandemic as stressful. The main challenges are parental affective symptoms and limited resources for childcare due to parenting stress. Overall, infants and toddlers show similar levels of mental health problems when being compared to pre-pandemic studies, but staggered detrimental effects on children`s mental health might occur if the stressful conditions persist. This is already indicated by correlations between parental and child psychosocial stress factors.

Sleep duration trajectories associated with levels of specific serum cytokines at age 5: A longitudinal study in preschoolers from the EDEN birth cohort

Sleep is essential for optimal child development and health during the life course. However, sleep disturbances are common in early childhood and increase the risk of cognitive, metabolic and inflammatory disorders throughout life. Sleep and immunity are mutually linked, and cytokines secreted by immune cells could mediate this interaction. The sleep modulation of cytokines has been studied mostly in adults and adolescents; few studies have focused on school-aged children and none on preschoolers. We hypothesized that night sleep duration affects cytokine levels in preschoolers. In a sample of 687 children from the EDEN French birth cohort, we studied the associations between night sleep duration trajectories from age to 2–5 years old and serum concentrations of four cytokines (Tumor necrosis factor α [TNF-α], Interleukin 6 [IL-6], IL-10, Interferon γ [IFN)-γ] at age 5, adjusting for relevant covariates. As compared with the reference trajectory (≈11h30/night sleep, 37.4% of children), a shorter sleep duration trajectory (<10 ​h/night, 4.5% of children), and changing sleep duration trajectory (≥11h30/night then 10h30/night, 5.6% of children) were associated with higher serum levels of IL-6 and TNF-α, respectively at age 5. We found no associations between sleep duration trajectories and IL-10 or IFN-γ levels. This first longitudinal study among children aged 2–5 years old suggests an impact of sleep duration on immune activity in early childhood. Our study warrants replication studies in larger cohorts to further explore whether and how immune activity interacts with sleep trajectories to enhance susceptibility to adverse health conditions.

Early regulatory problems and parenting: life-long risk, vulnerability or susceptibility for attention, internalizing and externalizing outcomes?

Multiple or persistent crying, sleeping, or feeding problems in early childhood (regulatory problems, RPs) predict increased risk for self-regulation difficulties. Sensitive parenting may protect children from trajectories of dysregulation. Considering self-regulation from a life-course perspective, are children with early multiple and/or persistent RPs affected similarly by parenting as those without (main effects model, ME), or are they more vulnerable (diathesis-stress, DIA-S), or more susceptible (differential susceptibility theory, DST) to variations in sensitive parenting at age 6 years? Participants (N = 302) were studied prospectively from birth to 28 years. RPs were assessed from 5 to 56 months. Sensitive parenting was observed at 6 years. Attention regulation was observed at 8 and 28 years. Internalizing and externalizing problems were rated by parents at 8 years, and by adults at 28 years. Confirmatory-comparative modelling tested whether associations of sensitive parenting with outcomes at 8 and 28 years among individuals with early multiple and/or persistent RPs (n = 74) versus those without (n = 228) were best explained by ME, DIA-S, or DST models. Best fitting models differed according to age at assessment. For childhood attention regulation, the statistically parsimonious DIA-S provided the best fit to the data. At age 28, two additive main effects (ME, RP group and sensitive parenting) fit best. DIA-S and ME explained internalizing and externalizing problems. Using a comprehensive life-span approach, DIA-S and ME models but not DST explained how early RPs and sensitive parenting predicted attention, internalizing, and externalizing outcomes. Individuals with early RPs are vulnerable to insensitive parenting.

Paternal adverse childhood experiences: Associations with infant DNA methylation

Adverse childhood experiences (ACEs), or cumulative childhood stress exposures, such as abuse, neglect, and household dysfunction, predict later health problems in both the exposed individuals and their offspring. One potential explanation suggests exposure to early adversity predicts epigenetic modification, especially DNA methylation (DNAm), linked to later health. Stress experienced preconception by mothers may associate with DNAm in the next generation. We hypothesized that fathers' exposure to ACEs also associates with their offspring DNAm, which, to our knowledge, has not been previously explored. An epigenome-wide association study (EWAS) of blood DNAm (n = 45) from 3-month-old infants was regressed onto fathers' retrospective ACEs at multiple Cytosine-phosphate-Guanosine (CpG) sites to discover associations. This accounted for infants' sex, age, ethnicity, cell type proportion, and genetic variability. Higher ACE scores associated with methylation values at eight CpGs. Post-hoc analysis found no contribution of paternal education, income, marital status, and parental postpartum depression, but did with paternal smoking and BMI along with infant sleep latency. These same CpGs also contributed to the association between paternal ACEs and offspring attention problems at 3 years. Collectively, these findings suggested there were biological associations with paternal early life adversity and offspring DNAm in infancy, potentially affecting offspring later childhood outcomes.

Recognizing Early Regulation Disorders in Pediatric Care: The For Healthy Offspring Project

Background

Regulation disorders are already apparent in infancy. The For Healthy Offspring Project was the first Hungarian study aimed at building an effective model for screening and examining the prevalence and complex (medical and psychosocial) background of classic behavior regulation disorders (excessive crying, feeding, and sleep problems) in infancy.

Material/Methods

Data were collected from families of 0- to 3-year-old children in a pediatric hospital and its neighboring areas through questionnaires, medical examinations, and individual and small-group consultations.

Results

In the questionnaire study about their children’s behavior (n=1133), 15% of mothers reported excessive crying, 16% reported feeding problems, and 10% reported sleep problems. In a subsample (n=619) in which medical examinations were also conducted, the prevalence of medical diagnoses was 15.0% for excessive crying, 15.2% for sleep disorders, 10.3% for breastfeeding difficulties, and 14.8% for feeding disorders. Children who were referred to the screening program (n=183) had significantly more behavior regulation disorders than the other children in our study. Regulation disorders were found to be comorbid with other health conditions in some cases.

Conclusions

We developed a complex model to screen for regulatory problems in early childhood. This study adds more information about the relationship between regulation problems and other health conditions. The general incidence (5–15%) of early childhood regulation disorders in other countries is likely similar to that found in Hungary. In order to effectively recognize early regulation disorders, diagnostic instruments widely used in the international field should be adapted in general Hungarian pediatric care.

Association Between Prescribed Hypnotics in Infants and Toddlers and Later ADHD: A Large Cohort Study from Norway

As previously indicated an association may exist between early sleep problems in infants and toddlers, and a diagnosis of attention deficit hyperactivity disorder (ADHD). The aim of this study was to study if this association could be replicated in a complete nationwide cohort of children. Prospective cohort study using national registries. All children born in Norway from January 2004 to December 2010 were included (N = 410,555). Information on hypnotic drugs dispensed to children 0-3 years of age outside of institutions was collected from the Norwegian Prescription Database and used as a proxy for sleep problems. The outcome ADHD (ICD-10), as diagnosed by specialists in the Child Mental Health Service, was obtained from the Norwegian Patient Registry. Data were analysed using weighted estimation in Cox regression. The unadjusted weighted hazard ratio (wHR) for a later diagnosis of ADHD in children dispensed two or more prescriptions for any hypnotic drug, compared to zero prescriptions, was 2.30 [95% confidence interval (CI) 1.63-3.23] for girls and 1.75 (95% CI 1.48-2.07) for boys. For the sedative antihistamine trimeprazine the corresponding wHR was 3.71 (95% CI 1.83-7.52) for girls and 2.78 (95% CI 2.04-3.80) for boys. After adjusting for parental ADHD and parental education the wHR for trimeprazine users was 2.81 (95% CI 1.34-5.88) for girls and 2.33 (95% CI 1.70-3.20) for boys. Infants and toddlers who were dispensed hypnotics had an increased risk of ADHD at school age. This association was most pronounced with the use of trimeprazine, a drug traditionally prescribed to toddlers for sleep problems in Norway. After adjusting for parental ADHD and educational level the risk for ADHD among the trimeprazine users was still more than twice the risk among controls.

Feeding and Eating Disorder and Risk of Subsequent Neurodevelopmental Disorders: A Population-Based Cohort Study

Background: There are limited data concerning the long-term mental health of children with feeding and eating disorder (FED). We aimed to investigate whether children with FED are at greater risks of developing emotional/behavioral disorders with onset usually during childhood, attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and intellectual disability (ID). Methods: We conducted a population-based cohort study, including all singleton births in Denmark from January 1, 1995, to December 31, 2015. For each child diagnosed with FED, 10 age- and sex-matched controls who did not meet the criteria for FED were randomly selected from the general population. Associations were estimated with Cox regression modes adjusting for other perinatal and maternal factors, and sibling analyses were performed for controlling potential confounding by shared familial (genetic or environmental) factors. Results: Of the 1,256,989 individuals in the cohort, there were 1967 (53.4% girls) children diagnosed with FED. Children with FED had higher risks for clinically diagnosed emotional/behavioral disorders with onset usually in childhood (hazard ratio [HR], 2.78; 95% CI, 2.34-3.31), ADHD (HR, 1.74; 95% CI, 1.33-2.26), ASD (HR, 3.05; 95% CI, 2.36-3.94), and ID (HR, 6.38; 95% CI, 4.48-9.11), compared with matched controls. Girls with FED are at greater risks for emotional/behavioral disorders and ID, but not ADHD and ASD. Alike, in sibling analysis, increased rates are also observed for other neurodevelopmental disorders, but not for ADHD. Conclusion: Children with FED are associated with substantially increased risks of emotional/behavioral disorders, ADHD, ASD, and ID. This study highlights the importance of carefully monitoring neurodevelopmental disorders in children with FED.

Health system utilization before age 1 among children later diagnosed with autism or ADHD

Children with autism spectrum disorder (ASD) or attention deficit hyperactivity disorder (ADHD) have 2-3 times increased healthcare utilization and annual costs once diagnosed, but little is known about their utilization patterns early in life. Quantifying their early health system utilization could uncover condition-specific health trajectories to facilitate earlier detection and intervention. Patients born 10/1/2006-10/1/2016 with ≥ 2 well-child visits within the Duke University Health System before age 1 were grouped as ASD, ADHD, ASD + ADHD, or No Diagnosis using retrospective billing codes. An additional comparison group was defined by later upper respiratory infection diagnosis. Adjusted odds ratios (AOR) for hospital admissions, procedures, emergency department (ED) visits, and outpatient clinic encounters before age 1 were compared between groups via logistic regression models. Length of hospital encounters were compared between groups via Mann-Whitney U test. In total, 29,929 patients met study criteria (ASD N = 343; ADHD N = 1175; ASD + ADHD N = 140). ASD was associated with increased procedures (AOR = 1.5, p < 0.001), including intubation and ventilation (AOR = 2.4, p < 0.001); and outpatient specialty care, including physical therapy (AOR = 3.5, p < 0.001) and ophthalmology (AOR = 3.1, p < 0.001). ADHD was associated with increased procedures (AOR = 1.41, p < 0.001), including blood transfusion (AOR = 4.7, p < 0.001); hospital admission (AOR = 1.60, p < 0.001); and ED visits (AOR = 1.58, p < 0.001). Median length of stay was increased after birth in ASD (+ 6.5 h, p < 0.001) and ADHD (+ 3.8 h, p < 0.001), and after non-birth admission in ADHD (+ 1.1 d, p < 0.001) and ASD + ADHD (+ 2.4 d, p = 0.003). Each condition was associated with increased health system utilization and distinctive patterns of utilization before age 1. Recognizing these patterns may contribute to earlier detection and intervention.

The association of infant crying, feeding, and sleeping problems and inhibitory control with attention regulation at school age

Regulatory problems in infancy and toddlerhood have previously been associated with an increased risk of developing attention problems in childhood. We hypothesized that early regulatory problems are associated with attention problems via reduced inhibitory control. This prospective study assessed 1,459 children from birth to 8 years. Crying, feeding, and sleeping problems were assessed at 5 and 20 months via parent interviews and neurological examinations. At 20 months, inhibitory control was tested with a behavioral (snack delay) task. Attention regulation was assessed at 6 and 8 years using multiple instruments and informants. Detrimental effects of crying, feeding, and sleeping problems on attention regulation were partly mediated by children's ability to inhibit unwanted behaviors (β = -0.04, p = 0.013). Accounting for cognition diminished this indirect effect (β = -0.01, p = 0.209). Instead, the effects of crying, feeding, and sleeping problems on attention regulation were fully mediated by children's cognitive functioning (β = -0.10, p < 0.001). These results support that inhibitory control abilities partly mediate effects of crying, feeding, and sleeping problems. However, these effects may be accounted for by children's general cognitive abilities. Early regulatory problems may set infants on a course of under control of behavior into school age, and such trajectories are highly associated with general cognitive development.

Executive function deficits mediate the association between very preterm birth and behavioral problems at school-age

BACKGROUND & AIMS

Children and adolescents born very preterm are at increased risk to develop executive function deficits and to suffer from social, emotional and attentional problems. This study investigated whether executive function deficits contribute to behavioral problems in children and adolescents born very preterm at school-age.

STUDY DESIGN

Thirty-eight children and adolescents born very preterm and 41 age-matched term-born peers were assessed at a mean age of 12.9 (±1.8) years with a comprehensive battery of executive function tests, including working memory, planning, cognitive flexibility, and verbal fluency. A composite score was calculated to reflect overall executive function abilities. To assess behavioral problems, parents completed the Strengths and Difficulties Questionnaire (SDQ). Mediation analysis was applied to quantify the effect of preterm birth on behavioral problems with executive function abilities as a mediating variable.

RESULTS

Executive function abilities were poorer in the very preterm compared to the term-born group (d = 0.62, p = .005) and the parents of very preterm children reported more behavioral problems on the SDQ Total Difficulties Score (d = 0.54, p = .01). The effect of birth status on behavioral problems was significantly mediated by executive function abilities while adjusting for age at assessment, sex, and socioeconomic status (F(2, 76) = 6.42, p = .002, R² = 0.14).

CONCLUSION

Results from this study suggest that the increase in behavioral symptoms in very preterm children at school-age compared to term-born peers may partly be explained by their executive function deficits. These findings highlight the importance of continuously monitoring the development of children born very preterm to provide optimal care as they grow up.

The better sleep better well-being programme: Educating and training community healthcare nurses in developing interventions for families of infants with moderate sleep problems: a pilot study

The main aim of this pilot study was to evaluate the benefit of the Better Sleep Better Well-being (BSBW) educational and training intervention programme regarding infants sleep problems for Community Health Care (CHC) nurses, on their perceptions on their family nursing practice skills and on their job demand, control and support. There were 6 CHC nurses who participated in the BSBW programme, and 26 nurses in the comparison group. The programme consisted of 4 sessions (8 hours per session) of lectures on the aetiology of infants sleep problems as well as on evidence-based and family relational practices and on 20 sessions of clinical cases, scenarios, discussions and reflections. The main finding indicated that the nurses in the intervention group reported significantly higher family nursing practices skills compared to the nurses in the comparison group. The findings are promising, since they offered additional resources to the CHC nurses, in their clinical practices.

Associations between infant and toddler regulatory problems, childhood co-developing internalising and externalising trajectories, and adolescent depression, psychotic and borderline personality disorder symptoms

BACKGROUND

Early regulatory problems (RPs) are associated with childhood internalising and externalising symptoms. Internalising and externalising symptoms, in turn, are associated with adolescent psychopathology (e.g. personality disorders, depression). We examined whether RPs are directly associated with adolescent psychopathology, or whether associations are indirect via childhood internalising and externalising symptoms.

METHODS

We used data from the Avon Longitudinal Study of Parents and Children. Mothers reported on their child's RPs at 6, 15-18 and 24-30 months, and internalising and externalising symptoms at 4, 7, 8 and 9.5 years. Adolescent psychotic, depression and BPD symptoms were assessed at 11-12 years. Children were grouped by their patterns of co-developing internalising and externalising symptoms using parallel process latent class growth analysis (PP-LCGA). Path analysis was used to examine direct and indirect associations from RPs to the three adolescent outcomes.

RESULTS

There were four groups of children with distinct patterns of co-developing internalising and externalising (INT/EXT) symptoms. Most children (53%) demonstrated low-moderate and stable levels of INT/EXT symptoms. A small proportion (7.7%) evidenced moderate and increasing INT and high stable EXT symptoms: this pattern was strongly predictive of adolescent psychopathology (e.g. depression at 11 years: unadjusted odds ratio = 5.62; 95% confidence intervals = 3.82, 8.27). The other two groups were differentially associated with adolescent outcomes (i.e. moderate-high increasing INT/moderate decreasing EXT predicted mother-reported depression at 12, while low stable INT/moderate-high stable EXT predicted child-reported depression at 11). In path analysis, RPs at each time-point were significantly indirectly associated with symptoms of BPD and child- and mother-reported depression symptoms via the most severe class of INT/EXT symptoms.

CONCLUSIONS

Consistent with a cascade model of development, RPs are predictive of higher levels of co-developing INT/EXT symptoms, which in turn increase risk of adolescent psychopathology. Clinicians should be aware of, and treat, early RPs to prevent chronic psychopathology.

Mapping infant neurodevelopmental precursors of mental disorders: How synthetic cohorts & computational approaches can be used to enhance prediction of early childhood psychopathology

Bridging advances in neurodevelopmental assessment and the established onset of common psychopathologies in early childhood with epidemiological data science and computational methods holds much promise for identifying risk for mental disorders as early as infancy. In particular, we propose the development of a mental health risk algorithm for the early detection of mental disorders with the potential for high public health impact that applies and adapts methods innovated in and successfully applied to early detection of cardiovascular risk. Specifically, we propose methods to advance risk prediction of early developmental psychopathology by creating synthetic cohorts that contain complete behavioral and neural data in the first years of life, as the basis for a robust and generalizable risk algorithm. The application of computational approaches within synthetic cohorts, an approach increasingly applied in psychiatry, may be particularly well suited to advancing risk prediction in early childhood mental health. We propose new research directions using these methods to generate an early childhood mental health risk calculator that could significantly advance early mental health risk detection to direct preventive intervention and/or need for more intensive assessment within a pragmatic framework for maximal clinical utility. The availability of such a tool in early childhood, a period of high neuroplasticity, holds promise to reduce the burden of mental disorder by identifying risk early in the clinical sequence and delivering prevention that targets the neurodevelopmental vulnerability phase.

Dysregulated Irritability as a Window on Young Children's Psychiatric Risk: Transdiagnostic Effects via the Family Check-Up

Building on prior work using Tom Dishion's Family Check-Up, the current article examined intervention effects on dysregulated irritability in early childhood. Dysregulated irritability, defined as reactive and intense response to frustration, and prolonged angry mood, is an ideal marker of neurodevelopmental vulnerability to later psychopathology because it is a transdiagnostic indicator of decrements in self-regulation that are measurable in the first years of life that have lifelong implications for health and disease. This study is perhaps the first randomized trial to examine the direct effects of an evidence- and family-based intervention, the Family Check-Up (FCU), on irritability in early childhood and the effects of reductions in irritability on later risk of child internalizing and externalizing symptomatology. Data from the geographically and sociodemographically diverse multisite Early Steps randomized prevention trial were used. Path modeling revealed intervention effects on irritability at age 4, which predicted lower externalizing and internalizing symptoms at age 10.5. Results indicate that family-based programs initiated in early childhood can reduce early childhood irritability and later risk for psychopathology. This holds promise for earlier identification and prevention approaches that target transdiagnostic pathways. Implications for future basic and prevention research are discussed.

Pre-emptive Intervention for Autism Spectrum Disorder: Theoretical Foundations and Clinical Translation

Autism spectrum disorders (ASD) are an emergent public health problem, placing significant burden upon the individual, family and health system. ASD are polygenetic spectrum disorders of neural connectome development, in which one or more feedback loops amplify small genetic, structural, or functional variations in the very early development of motor and sensory-motor pathways. These perturbations trigger a 'butterfly effect' of unpredictable cascades of structural and functional imbalances in the global neuronal workspace, resulting in atypical behaviors, social communication, and cognition long-term. The first 100 days post-term are critically neuroplastic and comprise an injury-sensitive developmental window, characterized by a neural biomarker, the persistence of the cortical subplate, and a behavioral biomarker, the crying diathesis. By the time potential diagnostic signs are identified, from 6 months of age, ASD neuropathy is already entrenched. The International Society for Autism Research Special Interest Group has called for pre-emptive intervention, based upon rigorous theoretical frames, and real world translation and evaluation. This paper responds to that call. It synthesizes heterogenous evidence concerning ASD etiologies from both psychosocial and biological research literatures with complexity science and evolutionary biology, to propose a theoretical framework for pre-emptive intervention. This paper hypothesizes that environmental factors resulting from a mismatch between environment of evolutionary adaptedness and culture initiate or perpetuate early motor and sensory-motor lesions, triggering a butterfly effect of multi-directional cascades of atypical developmental in the complex adaptive system of the parent and ASD-susceptible infant. Chronic sympathetic nervous system/hypothalamic-pituitary-adrenal axis hyperarousal and disrupted parent-infant biobehavioral synchrony are the key biologic and behavioral mechanisms perpetuating these atypical developmental cascades. A clinical translation of this evidence is proposed, for application antenatally and in the first 6 months of life, as pre-emptive intervention for ASD.

Infant crying problems and symptoms of sleeping problems predict attachment disorganization at 18 months

This longitudinal study examined the associations among infant crying, symptoms of sleeping problems, and attachment while considering the influence of maternal sensitivity and depressive symptoms. One hundred and five healthy full-term infants (42.9% female) were assessed for crying and symptoms of sleeping problems at 3 and 18 months via parental interview. Maternal sensitivity was measured through researcher observation, and attachment was measured at 18 months using the Strange Situation procedure. It was found that infant crying and symptoms of sleeping problems were not linked to the organized patterns of secure or insecure (avoidant versus resistant) attachment. However, when the disorganized attachment was considered, there were direct links found from infant crying and symptoms of sleeping problems at 3 months (β= .22, p< .05) and 18 months (β= .21, p< .05). Thus, crying and symptoms of sleeping problems as early as 3 months may indicate a disruption in the coherence of infants' relationship to their caretakers.

Future Directions for Early Childhood Prevention of Mental Disorders: A Road Map to Mental Health, Earlier

Mental disorders are the predominant chronic diseases of youth, with substantial life span morbidity and mortality. A wealth of evidence demonstrates that the neurodevelopmental roots of common mental health problems are present in early childhood. Unfortunately, this has not been translated to systematic strategies for improving population-level mental health at this most malleable neurodevelopmental period. We lay out a translational Mental Health, Earlier road map as a key future direction for prevention of mental disorder. This paradigm shift aims to reduce population attributable risk of mental disorder emanating from early life, by preventing, attenuating, or delaying onset/course of chronic psychopathology via the promotion of self-regulation in early childhood within large-scale health care delivery systems. The Earlier Pillar rests on a "science of when to worry" that (a) optimizes clinical assessment methods for characterizing probabilistic clinical risk beginning in infancy via deliberate incorporation of neurodevelopmental heterogeneity, and (b) universal primary-care-based screening targeting patterns of dysregulated irritability as a robust transdiagnostic marker of vulnerability to life span mental health problems. The core of the Healthier Pillar is provision of low-intensity selective intervention promoting self-regulation for young children with developmentally atypical patterns of irritability within an implementation science framework in pediatric primary care to ensure highest population impact and sustainability. These Mental Health, Earlier strategies hold much promise for transforming clinical outlooks and ensuring young children's mental health and well-being in a manner that reverberates throughout the life span.
