"When you're hurt and you need serious help you call 999." Educating children about emergency services and appropriate use of 999: An evaluation study of the Blue Light Hub app.

OBJECTIVES: In the face of unprecedented demand, the Welsh Ambulance Services University NHS Trust developed 'Blue Light Hub': a new app to educate primary school-aged children about emergency services. Our overarching aim was to examine the effectiveness of the app. DESIGN: Primary school-aged children from three schools in South Wales, UK, played with the app for 2 hours over 2 weeks in class time. Children completed quizzes to assess their knowledge and awareness of, and confidence in engaging with, emergency services before and after using the app. PARTICIPANTS: Our evaluation focused on N=393 children who completed both the pre-test and post-test quizzes. On average, children were 8-9 years old (median school year, Year 4); 47.8% were male and 50.9% were female. RESULTS: After using the app, there was a significant increase in the proportion of children who knew of appropriate actions to take in non-emergency scenarios, χ2(1) = 26.01, and could provide a question a call handler would ask them if they called 999, χ2(1) = 13.79. There was also an increase in the proportion of children who could identify an National Health Service (NHS) service that could help them if they were unwell, χ2(1) = 33.31, name different roles in the NHS, χ2(1) = 12.80 and knew how dialling 111 could help them χ2(1) = 90.05 (all p values<0.001). CONCLUSION: To our knowledge, Blue Light Hub is the first app of its kind designed to educate primary school-aged children about emergency services. Our findings provide preliminary evidence that the app supports children's knowledge and awareness of emergency services.

Neurodevelopmental dimensional assessment of young children at high genomic risk of neuropsychiatric conditions.

Background: Individuals with 22q11.2 deletion are at considerably increased risk of neurodevelopmental and psychiatric conditions. There have been very few studies investigating how this risk manifests in early childhood and what factors may underlie developmental variability. Insights into this can elucidate transdiagnostic markers of risk that may underlie later development of neuropsychiatric outcomes. Methods: Thirty two children with 22q11.2 Deletion Syndrome (22q11.2DS) (mean age = 4.1 [SD = 1.2] years) and 12 sibling controls (mean age = 4.1 [SD = 1.5] years) underwent in-depth dimensional phenotyping across several developmental domains selected as being potential early indicators of neurodevelopmental and psychiatric liability. Comparisons were conducted of the dimensional developmental phenotype of 22q11.2DS and sibling controls. For autistic traits, both parents and children were phenotyped using the Social Responsiveness Scale. Results: Young children with 22q11.2DS exhibited large impairments (Hedge's g ≥ 0.8) across a range of developmental domains relative to sibling controls, as well as high rates of transdiagnostic neurodevelopmental and psychiatric traits. Cluster analysis revealed a subgroup of children with 22q11.2DS (n = 16; 53%) in whom neurodevelopmental and psychiatric liability was particularly increased and who differed from other children with 22q11.2DS and non-carrier siblings. Exploratory analyses revealed that early motor and sleep impairments indexed liability for neurodevelopmental and psychiatric outcomes. Maternal autism trait scores were predictive of autism traits in children with 22q11.2DS (intraclass correlation coefficients = 0.47, p = 0.046, n = 31). Conclusions: Although psychiatric conditions typically emerge later in adolescence and adulthood in 22q11.2DS, our exploratory study was able to identify a range of early risk indicators. Furthermore, findings indicate the presence of a subgroup who appeared to have increased neurodevelopmental and psychiatric liability. Our findings highlight the scope for future studies of early risk mechanisms and early intervention within this high genetic risk patient group.

Overlapping brain correlates of superior cognition among children at genetic risk for Alzheimer's disease and/or major depressive disorder.

Early life adversity (ELA) tends to accelerate neurobiological ageing, which, in turn, is thought to heighten vulnerability to both major depressive disorder (MDD) and Alzheimer's disease (AD). The two conditions are putatively related, with MDD representing either a risk factor or early symptom of AD. Given the substantial environmental susceptibility of both disorders, timely identification of their neurocognitive markers could facilitate interventions to prevent clinical onset. To this end, we analysed multimodal data from the Adolescent Brain and Cognitive Development study (ages 9-10 years). To disentangle genetic from correlated genetic-environmental influences, while also probing gene-adversity interactions, we compared adoptees, a group generally exposed to substantial ELA, with children raised by their biological families via genetic risk scores (GRS) from genome-wide association studies. AD and MDD GRSs predicted overlapping and widespread neurodevelopmental alterations associated with superior fluid cognition. Specifically, among adoptees only, greater AD GRS were related to accelerated structural maturation (i.e., cortical thinning) and higher MDD GRS were linked to delayed functional neurodevelopment, as reflected in compensatory brain activation on an inhibitory control task. Our study identifies compensatory mechanisms linked to MDD risk and highlights the potential cognitive benefits of accelerated maturation linked to AD vulnerability in late childhood.

Facial emotion recognition in adopted children.

Children adopted from public care are more likely to experience emotional and behavioural problems. We investigated two aspects of emotion recognition that may be associated with these outcomes, including discrimination accuracy of emotions and response bias, in a mixed-method, multi-informant study of 4-to-8-year old children adopted from local authority care in the UK (N = 42). We compared adopted children's emotion recognition performance to that of a comparison group of children living with their birth families, who were matched by age, sex, and teacher-rated total difficulties on the Strengths and Difficulties Questionnaire (SDQ, N = 42). We also examined relationships between adopted children's emotion recognition skills and their pre-adoptive histories of early adversity (indexed by cumulative adverse childhood experiences), their parent- and teacher-rated emotional and behavioural problems, and their parents' coded warmth during a Five Minute Speech Sample. Adopted children showed significantly worse facial emotion discrimination accuracy of sad and angry faces than non-adopted children. Adopted children's discrimination accuracy of scared and neutral faces was negatively associated with parent-reported behavioural problems, and discrimination accuracy of angry and scared faces was associated with parent- and teacher-reported emotional problems. Contrary to expectations, children who experienced more recorded pre-adoptive early adversity were more accurate in identifying negative emotions. Warm adoptive parenting was associated with fewer behavioural problems, and a lower tendency for children to incorrectly identify faces as angry. Study limitations and implications for intervention strategies to support adopted children's emotion recognition and psychological adjustment are discussed.

Adoptive parents' finances and employment status: a 5-year longitudinal study.

We investigated risk and facilitating factors related to families' change in finances and employment over 5 years following adoption of a child from local authority care in a prospective, longitudinal study of children placed for adoption between 2014 and 2015 (N = 96). Parents completed questionnaires at approximately 5, 21, 36, 48 and 60 months post-placement. We used time series analysis to examine the impact of child (e.g. pre-placement experiences, mental health), family structure (e.g. number of siblings, parent relationship status), and parent (e.g. mental health) factors on change in household income and parent employment status after adoption. We also examined the tendency for parents to comment on employment and finances and the emotional valence of their comments to gauge their concern about their circumstances. Children's mental health problems were associated with primary caregivers reducing their time spent in employment and parents' tendency to comment on their financial and work circumstances. Children who experienced more moves in care were more likely to have a primary caregiver not in full-time work, as were children with higher prosocial behaviour scores. Being in full-time work was associated with parents' symptoms of anxiety. We also detected associations between structural features of the family and changes in income and employment. This study represents one of the first empirical investigations of factors associated with the socioeconomic features of adoptive families' lives and informs ongoing discussion regarding the support needs of families and the timing, nature, and delivery of post-adoption professional services.

The impact of a specialist home-visiting intervention on the language outcomes of young mothers and their children: a pragmatic randomised controlled trial.

BACKGROUND: Young mothers are more likely to provide a suboptimal early language environment for their children who in turn show impairments in their language development, yet few studies have used observational methods to assess the effectiveness of home-visiting programmes in improving the language outcomes of young mothers and their children. The Family Nurse Partnership (FNP) is a licensed home-visiting intervention developed in the USA and introduced into practice in England. The intervention involves up to 64 structured home visits from early pregnancy until the child's second birthday by specially recruited and trained Family Nurses. We assessed the effectiveness of FNP in improving the language outcomes of first-time teenage mothers and their infants. METHOD: We conducted a pragmatic, non-blinded, randomised controlled trial to test whether the FNP programme improved mothers' and children's language production at 24 months postpartum. Eligible participants were nulliparous, aged 19 years or younger, and were recruited at less than 25 weeks' gestation from community midwifery settings (Country). Pregnant young mothers were randomly assigned to FNP plus usual care (n = 243) or usual care alone (n = 233). At 24 months postpartum, mother-child dyads were observed during a standardised free-play task with their first-born child and features of their language production was coded. Data was analysed using multi-level modelling; linear or poisson/negative binomial regression models were used as appropriate. RESULTS: A small effect of FNP on mothers' productive language was detected, where mothers in the FNP group demonstrated higher mean length of utterances than mothers who received usual care alone, mean difference (adjusted by minimisation variables and by site, linear regression) = 0.10, p < .05, 95% CI (0.004-0.20), d = .18. No differences were detected between groups regarding other characteristics of maternal language or children's language outcomes. CONCLUSION: This observational study conducted within the context of a randomised-controlled trial suggests that the FNP home-visiting programme may have a small, but potentially important impact on young mothers' speech to their toddlers. Exploratory analyses identified family environment, maternal, and child related predictors of the language outcomes of young mothers and their offspring.

"A pirate goes nee-nor-nee-nor!" humor with siblings in middle childhood: A window to social understanding?

Humor is a central feature of close and intimate relationships in childhood. However, fundamental questions regarding the relationship between humor production, pretend play, and social understanding have been overlooked. In a selected subsample from a prospective longitudinal study of first-born children (N = 110, M age = 6.91 years, 46.4% female, 98.1% parents identified as English, Welsh, Scottish, or Irish), we conducted detailed observational coding of children's humor production during dress-up play with younger siblings. Focal children also completed a battery of social understanding tasks that measured emotion understanding and second-order belief understanding. Focal children were also observed during solo free play with Playmobil, and their spontaneous references to others' cognitions and play with objects were coded. Correlation analyses indicated that children's word play with their sibling was associated with their tendency to engage in pretense during solo play. Regression analyses showed that humorous sound play with siblings was associated with their emotion understanding and playful teasing with siblings was associated with their spontaneous references to others' cognitive states during solo free play. Our findings contribute to knowledge and theory regarding domains of development associated with humor production in childhood. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Doll play prompts social thinking and social talking: Representations of internal state language in the brain.

Doll play provides opportunities for children to practice social skills by creating imaginary worlds, taking others' perspectives, and talking about others' internal states. Previous research using functional near-infrared spectroscopy (fNIRS) found a region over the posterior superior temporal sulcus (pSTS) was more active during solo doll play than solo tablet play, implying that doll play might present opportunities for rehearsing theory of mind and empathy skills, even when playing alone. In this research, we addressed this more directly by investigating 4-8-year-old children's (N = 33) use of internal state language (ISL; i.e., references to emotions, desires, and cognitions) when playing with dolls and on tablets, both by themselves and with a social partner, and their associated brain activity in the pSTS using fNIRS. We found that children used more ISL about others when playing with dolls than when playing on tablets, particularly when they were playing alone. This mirrored the patterns seen in pSTS activity in previous research. When individual variability in ISL about others was considered, more ISL about others was linked to stronger pSTS activation. Thus, variability in pSTS activity during play is not about the perceptual or physical differences between toys (e.g., dolls are more human-like) but about what children think about when they engage in different kinds of play. This is the first research to investigate brain activity during spontaneously occurring ISL and indicates that children have a tendency to take and discuss others' perspectives during doll play, with implications for social processing in the brain.

Seven-year-olds' references to internal states when playing with toy figures and a video game.

References to internal states (e.g., thoughts, feelings, and desires) indicate children's appreciation of people's inner worlds. Many children spend time playing video games; however, the nature of children's speech when doing so has received little attention. We investigated the use of internal state language (ISL) as 251 seven-year-olds played with toy figures and a video game designed for the study. Although children used ISL more when playing with toy figures, children used ISL in both contexts, highlighting video game play as a context where children demonstrate their appreciation of inner worlds. Children's speech in the two contexts differed in how ISL was used: references to children's own internal states were more common when playing the video game, and the characters' internal states more common when playing with the toy figures. These findings are discussed with reference to the format of the play activities affording different opportunities to discuss internal states. HIGHLIGHTS: In traditional play children refer to internal states, however, it is unclear whether this occurs when they play video games.Children referred to internal states when playing with toy figures and a video game, but did so more with the toys.Children's video game play can be used as a new context for the study of children's social understanding.

Prosocial and Aggressive Behavior: A Longitudinal Study.

Developmental theorists have made strong claims about the fundamental prosocial or aggressive nature of the human infant. However, only rarely have prosocial behavior and aggression been studied together in the same sample. We charted the parallel development of both behaviors from infancy to childhood in a British community sample, using a two-construct, multimethod longitudinal design. Data were drawn from the Cardiff Child Development Study (CCDS), a prospective longitudinal study of a volunteer sample of parents and their firstborn children. A sample of 332 mothers was recruited from National Health Service (NHS) prenatal clinics and general practice clinics in Wales, UK, between Fall of 2005 and Summer of 2007. Potential participants represented the full range of sociodemographic classifications of neighborhoods. Participating families were divided about equally between middle- and working-class families, were somewhat more likely to have sons than daughters, and the majority (90%) were in a stable partnership. In response to standard categories recommended for use in Wales at the time, the majority (93%) of mothers reported themselves as Welsh, Scottish, English, or Irish; most others named a European or South Asian nationality. Of the 332 families agreeing to participate, 321 mothers (Mage = 28 years) and 285 partners (Mage = 31 years) were interviewed during the pregnancy and 321 of the families contributed data at least once after the child's birth. After an initial home visit at 6 months, data collection occurred in four additional waves of testing when children's mean ages were approximately 1, 1.5, 2.5, and 7 years. Data collection alternated between family homes and Cardiff University. Of those families seen after the child's birth, 89% were assessed at the final wave of testing. Data collection ended in 2015. Methods included direct observation, experimental tasks, and collection of reports from mothers, fathers, other relatives or family friends, and classroom teachers. Interactions with a familiar peer were observed at 1.5 years. Interactions with unfamiliar peers took place during experimental birthday parties at 1 and 2.5 years. At 7 years, parents were interviewed, parents and teachers completed questionnaires, and the children engaged in cognitive and social decision-making tasks. Based on reports from parents and other informants who knew the children well, individual differences in both prosocial behavior and aggression were evident in children. Both types of behavior showed stability across the second and third years. The association between prosocial behavior and aggression changed over time: at 1.5 years, they were not significantly related (the association approached zero), but they became negatively correlated by 3 years. Different patterns were seen when children played with familiar versus unfamiliar peers. At 1.5 years, when children were observed at home with a familiar peer, prosocial behavior and aggression were unrelated, thus showing a pattern of results like that seen in the analysis of informants' reports. However, a different pattern emerged during the experimental birthday parties with unfamiliar peers: prosocial behavior and aggression were positively correlated at both 1 and 2.5 years, contributing to a general sociability factor at both ages. Gender differences in prosocial behavior were evident in informants' reports and were also evident at the 1-year (though not the 2.5-year) birthday parties. In contrast, gender differences in both prosocial behavior and aggression were evident by 7 years, both in children's aggressive decision-making and in their parents' and teachers' reports of children's aggressive behavior at home and school. By age 7, children's aggressive decision-making and behavior were inversely associated with their verbal skills, working memory, and emotional understanding. Some children had developed aggressive behavioral problems and callous-unemotional traits. A few (12%) met diagnostic criteria for conduct disorder or oppositional-defiant disorders, which had been predicted by early angry aggressiveness and lack of empathy for other people. Taken together, the findings revealed a gradual disaggregation of two ways in which children interact with other people. Individual differences in both prosocial behavior and aggression revealed continuity over time, with gender differences emerging first in prosocial behavior, then in aggression. Restrictions in the participant sample and the catchment area (e.g., all were first-time parents; all were drawn from a single region in the United Kingdom) mean that it is not possible to generalize findings broadly. It will be important to expand the study of prosocial behavior and aggression in other family and environmental contexts in future work. Learning more about early appearing individual differences in children's approaches to the social world may be useful for both educational and clinical practice.

Early adversity predicts adoptees' enduring emotional and behavioral problems in childhood.

Children adopted from the public care system are likely to experience a cluster of inter-related risk factors that may place them on a trajectory of mental health problems that persist across the life course. However, the specific effects of putative risk factors on children's mental health post-placement are not well understood. We conducted a prospective, longitudinal study of children placed for adoption between 2014 and 2015 (N = 96). Adoptive parents completed questionnaires at approximately 5, 21, 36, and 48 months post-placement. We used time series analysis to examine the impact of pre-adoptive risk factors [adverse childhood experiences [ACEs], number of moves, days with birth parents and in care] on children's internalizing and externalizing problems, and prosocial behavior over 4 years post-placement. Adoptees' internalizing and externalizing problems remained consistently high over the 4-year study period, but more ACEs predicted increases in internalizing and externalizing problems. Contrary to expectations, more pre-placement moves and time in care predicted fewer problems over time, but exploratory analyses of interactive effects revealed this was only the case in rare circumstances. We identify pre- and post-removal factors that may incur benefits or have a deleterious impact on adoptees' outcomes in post-adoptive family life. Our findings provide knowledge for front-line professionals in the support of adoptive families and underscore the vital need for effective early intervention.

The neurocognitive profiles of children adopted from care and their emotional and behavioral problems at home and school.

Adoptees' mental health problems in childhood and later life are well described, but little attention has been paid to domestically adopted children's emotional and behavioral problems and neurocognitive profiles. The aim of this study was to describe the neurocognitive profiles of domestically adopted children in the UK and their parent- and teacher-rated emotional and behavioral problems. Forty-five children (M age = 75.96 months, SD = 12.98; 51.1% female) who were placed for adoption from public care at a M age of 22.14 months (SD = 14.21) completed a battery of age standardized neurocognitive tests, and adoptive parents and school teachers rated their emotional and behavioral problems. Children had more emotional and behavioral problems than the general population and over a fifth scored low (> 1 SD below the expected range for their age) in 5/6 neurocognitive tasks. Children who scored low on the non-verbal reasoning task were more likely to have more parent- and teacher-rated behavioral problems, and children's performance on the inhibitory control and cognitive flexibility tasks were associated with parent-rated behavioral problems. Children's verbal reasoning scores were positively associated with both parent- and teacher-rated emotional problems. Children who were adopted later in childhood scored significantly lower in non-verbal reasoning. Although longitudinal studies are needed to clarify the nature of neurocognitive functioning as a marker for later mental health problems, our findings underscore the importance of using comprehensive assessments to better recognize adopted children's difficulties and inform appropriate intervention initiatives.

Charting the trajectories of adopted children's emotional and behavioral problems: The impact of early adversity and postadoptive parental warmth.

Children who are adopted from care are more likely to experience enduring emotional and behavioral problems across development; however, adoptees' trajectories of mental health problems and factors that impact their trajectories are poorly understood. Therefore, we used multilevel growth analyses to chart adoptees' internalizing and externalizing problems across childhood, and examined the associations between preadoptive risk and postadoptive protective factors on their trajectories. This was investigated in a prospective longitudinal study of case file records (N = 374) and questionnaire-based follow-ups (N = 96) at approximately 5, 21, and 36 months postadoptive placement. Preadoptive adversity (indexed by age at placement, days in care, and number of adverse childhood experiences) was associated with higher internalizing and externalizing scores; the decrease in internalizing scores over childhood was accelerated for those exposed to lower levels of preadoptive risk. Warm adoptive parenting was associated with a marked reduction in children's internalizing and externalizing problems over time. Although potentially limited by shared methods variance and lack of variability in parental warmth scores, these findings demonstrate the deleterious impact of preadoptive risk and the positive role of exceptionally warm adoptive parenting on children's trajectories of mental health problems and have relevance for prevention and intervention strategies.

Continuity and change in anger and aggressiveness from infancy to childhood: The protective effects of positive parenting.

Early signs of anger and aggression can be identified in infancy. Our aim was to use person-centered methods to identify which infants were most at risk for clinically significant behavioral problems by age 3 and diagnoses of ODD/CD by 7 years, while considering the role of family risk factors and positive parenting. A representative British community sample of 304 infants was assessed by multiple informants at mean ages of 6, 21, and 36 months of age. Latent Transition Analysis (LTA) identified three ordered subgroups at each age, with one subgroup (18%) displaying high levels of physical force as well as anger. These angry aggressive infants were at elevated risk for behavioral problems in early childhood and diagnoses of conduct disorder (CD) and/or oppositional defiant disorder (ODD) at 7 years of age. After other risk factors were taken into account, parents' beliefs in warm parenting and their observed positive affect while interacting with their infants were protective factors. These findings indicate the significance of very early manifestations of angry aggressiveness and have relevance for developmental theories of aggression and prevention strategies.

Assessing the impact of a family nurse-led intervention on young mothers' references to internal states.

A mother's propensity to refer to internal states during mother-child interactions is important for her child's developing social understanding. However, adolescent mothers are less likely to reference internal states when interacting with their children. We investigated whether young mothers' references to internal states are promoted by the Family Nurse Partnership (FNP) intervention, an intensive home-visiting programme designed to support adolescent mothers in England. We also investigated family, maternal, and child factors associated with young mothers' references to inner states during interactions with their children. Adolescent mothers (n = 483, aged ≤ 19 years when recruited in pregnancy) and their children participated in an observational substudy of a randomized controlled trial investigating the impact of FNP compared to usual care. Mother-child dyads were video-recorded during free play, and mothers' speech was coded for use of internal state language (references to cognitions, desires, emotions, intentions, preferences, physiology, and perception). We found no differences in mothers' use of internal state language between the FNP and usual care groups. A sample-wide investigation identified that other features of mothers' language and relationship status with the child's father were associated with internal state language use. Findings are discussed with reference to targeted interventions and implications for future research.

La tendencia de la madre a referirse a los estados internos durante las interacciones madre-niño es importante para el desarrollo social cognitivo de su niño. Sin embargo, las madres adolescentes están menos propensas a referirse a los estados internos cuando interactúan con sus niños. Investigamos si la tendencia de las madres jóvenes a referirse a estados internos es promovida por la intervención de Asociación entre Familia y Enfermera (FNP), un programa intensivo de visitas a casa diseñado para apoyar a madres adolescentes en el Reino Unido. También investigamos factores de familia, maternos y del niño asociados con las interacciones de las jóvenes madres con sus niños. Las madres adolescentes (n = 483, edad ≤ 19 años) y sus niños participaron en un sub-estudio de observación, un ensayo controlado al azar que investigaba el impacto de FNP comparado con el cuidado usual. Las díadas madre-niño fueron grabadas en video durante el juego libre, y se codificó el habla de las madres en cuanto al uso del lenguaje de estados internos (referencias a cogniciones, deseos, emociones, intenciones, preferencias, fisiología y percepción). No encontramos diferencias en cuanto al uso del lenguaje de estados internos en las madres entre la FNP y los grupos de cuidado usual. Una muestra de investigación amplia identificó que otras características del lenguaje de las madres y condiciones de la relación con el padre del niño estaban asociadas con el uso del lenguaje de estados internos. Los resultados se discuten con referencia a intervenciones elegidas como objetivo e implicaciones para la futura investigación.

La propension d'une mère à faire référence à ses états internes durant les interactions mère-enfant est importante pour le développement social et cognitif de son enfant. Cependant, les mères adolescentes sont moins à même de faire référence à leurs états internes dans leur interaction avec leurs enfants. Notre étude a porté sur si la propension des jeunes mères à faire référence à leurs états internes est promue par l'intervention Partenariat Famille Infirmières (en anglais Family Nurse Partnership, soit FNP), un programme intensif de visite à domicile conçu afin de soutenir les mères adolescentes au Royaume Uni. Nous avons également étudié les facteurs familiaux, maternels, et liés aux enfants, liés aux interactions des jeunes mères avec leurs enfants. Les mères adolescentes (n = 483, âgés ≤ 19 ans) et leurs enfants ont participé à une sous-étude observationnelle d'un essai contrôlé randomisé portant sur l'impact de la FNP comparé aux soins normaux. Les dyades mères-enfant ont été filmées durant un jeu libre et les paroles des mères ont été codées pour son utilisation de langage d'état interne (références aux cognitions, désirs, émotions, intentions, préférences, physiologie et perception). Nous n'avons trouvé aucune différence dans l'utilisation des mères du langage d'état interne entre le groupe FNP et les groupes de contrôle. Une étude de l'échantillon a révélé que d'autres traits du langage des mères et du statut de la relation avec le père de l'enfant étaient liés à l'utilisation de langage de l'état interne. Les résultats sont discutés par rapport aux interventions ciblées et aux implications pour les recherches futures.

Depression and Anxiety Symptoms of British Adoptive Parents: A Prospective Four-Wave Longitudinal Study.

The mental health of birth parents has gained attention due to the serious negative consequences for personal, family, and child outcomes, but depression and anxiety in adoptive parents remains under-recognized. Using a prospective, longitudinal design, we investigated anxiety and depression symptoms in 96 British adoptive parents over four time points in the first four years of an adoptive placement. Depression and anxiety symptom scores were relatively stable across time. Growth curve analysis showed that higher child internalizing scores and lower parental sense of competency at five months post-placement were associated with higher initial levels of parental depressive symptoms. Lower parental sense of competency was also associated with higher initial levels of parental anxiety symptoms. Parents of older children and those with higher levels of parental anxiety and sense of competency at five months post-placement had a steeper decrease in depressive symptoms over time. Support for adoptive families primarily focuses on child adjustment. Our findings suggest that professional awareness of parental mental health post-placement may be necessary, and interventions aimed at improving parents' sense of competency may be beneficial.

Adverse Childhood Experiences of Children Adopted from Care: The Importance of Adoptive Parental Warmth for Future Child Adjustment.

We investigated the relationship between adverse childhood experiences (ACEs) and children's internalising symptoms and externalising problems in the Wales Adoption Cohort Study, a prospective longitudinal study that used case file records (n = 374) for a sample of British children adopted from care (M = 2 years, 55% male). Parents (n = 96) completed questionnaires at 3-5 months, 15-17 months, and 31-33 months post-placement. We hypothesised that: (1) children adopted from care would have experienced more ACEs than children in the general population; (2) the number of ACEs would be associated with higher internalising symptom and externalising problem scores; and (3) adoptive parental warmth would moderate the relationship between ACEs and post-placement internalising symptoms and externalising problems. Nearly half (42%) of the children experienced four or more ACEs. Internalising symptoms and externalising problems were significantly higher than the UK general population. The number of ACEs was associated with internalising symptoms 3 years post-adoptive placement but this relationship was moderated by adoptive parental warmth. This study profiles the experiences and characteristics of a national sample of adopted children and highlights the potential importance of parent warmth as a factor that ameliorates the impact of ACEs on poor child outcomes.

'H, I, J, K, L, M, N, O, PEE! Get it? Pee!': Siblings' shared humour in childhood.

Humour is a central feature of social interactions in childhood that has received little attention. In a sample of 86 7-year-old children (M age = 7.82 years, SD = 0.80), we investigated patterns and individual differences in spontaneous humour observed during free play with their older (M age = 9.55 years, SD = 0.88) or their younger sibling (M age = 5.87 years, SD = 0.96). We coded children's instances, categories, and responses to humour. We investigated the nature of children's humour on the dyadic and individual level. Humour was common, and siblings' production of humour was highly interdependent between play partners. Dyadic humour differed according to structural features of the sibling relationship (age, gender composition), and 7-year-old focal children's humour varied according to gender. This study contributes to knowledge regarding the dyadic nature of children's humour and individual patterns of humour beyond the preschool years. Statement of contribution What is already known on this subject? Humour is an integral part of children's close and intimate interactions. Children produce humour from an early age and increasingly produce more complex humour as they develop. Few studies examine children's humour with siblings and beyond the fourth year of life. What does this study add? Children's humour during free play with siblings was common and highly dyadic. Sibling dyads' humour differed according to age and gender composition. Seven-year-old boys produced more humour than girls.

Concurrent associations between mothers' references to internal states and children's social understanding in middle childhood.

Although it is well established that features of maternal speech are associated with children's social understanding in the preschool years, few studies explore this relationship in middle childhood. Within the context of a prospective longitudinal study of a representative community sample of families (subsample n = 207, mean age = 82.88 months), we investigated concurrent associations between mothers' internal state language and aspects of 7-year-olds' social understanding, including children's understanding of belief and spontaneous references to internal states during free play. When sociodemographic, maternal, and child characteristics were controlled, mothers' references to their own cognitions were associated with dimensions of children's social understanding. Our findings suggest that exposure to others' perspectives contributes to children's advanced understanding of minds, which has implications for interventions that foster social understanding.

Late, but not early, arriving younger siblings foster firstborns' understanding of second-order false belief.

This study examined the influence of younger siblings on children's understanding of second-order false belief. In a representative community sample of firstborn children (N=229) with a mean age of 7years (SD=4.58), false belief was assessed during a home visit using an adaptation of a well-established second-order false belief narrative enacted with Playmobil figures. Children's responses were coded to establish performance on second-order false belief questions. When controlling for verbal IQ and age, the existence of a younger sibling predicted a twofold advantage in children's second-order false belief performance, yet this was the case only for firstborns who experienced the arrival of a sibling after their second birthday. These findings provide a foundation for future research on family influences on social cognition.
