The effect of oxytocin nasal spray on social interaction in young children with autism: a randomized clinical trial.

Early supports to enhance social development in children with autism are widely promoted. While oxytocin has a crucial role in mammalian social development, its potential role as a medication to enhance social development in humans remains unclear. We investigated the efficacy, tolerability, and safety of intranasal oxytocin in young children with autism using a double-blind, randomized, placebo-controlled, clinical trial, following a placebo lead-in phase. A total of 87 children (aged between 3 and 12 years) with autism received 16 International Units (IU) of oxytocin (n = 45) or placebo (n = 42) nasal spray, morning and night (32 IU per day) for twelve weeks, following a 3-week placebo lead-in phase. Overall, there was no effect of oxytocin treatment over time on the caregiver-rated Social Responsiveness Scale (SRS-2) (p = 0.686). However, a significant interaction with age (p = 0.028) showed that for younger children, aged 3-5 years, there was some indication of a treatment effect. Younger children who received oxytocin showed improvement on caregiver-rated social responsiveness ( SRS-2). There was no other evidence of benefit in the sample as a whole, or in the younger age group, on the clinician-rated Clinical Global Improvement Scale (CGI-S), or any secondary measure. Importantly, placebo effects in the lead-in phase were evident and there was support for washout of the placebo response in the randomised phase. Oxytocin was well tolerated, with more adverse side effects reported in the placebo group. This study suggests the need for further clinical trials to test the benefits of oxytocin treatment in younger populations with autism.Trial registration www.anzctr.org.au (ACTRN12617000441314).

Social and joint attention during shared book reading in young autistic children: a potential marker for social development.

BACKGROUND: Atypical patterns of social engagement and joint attention behaviors are diagnostic criteria for people with autism spectrum disorder. Experimental tasks using eye-tracking methodologies have, however, shown inconsistent results. The development of tasks with greater ecological validity and relevance for developmentally appropriate social milestones has been identified as important for the field. METHODS: We developed a novel, dynamic eye-tracking task emulating a shared book reading (SBR) scenario. Four SBR videos of an adult reader engaging with the viewer while reading a children's picture book and including sequenced bids for joint attention were developed. Participants included 90 children (N = 56 autistic children, N = 34 neurotypical children; aged 3-12). Social attention was also measured in a live free play task between participants and an experimenter. RESULTS: Compared to neurotypical children, autistic children displayed reduced attention to socially salient stimuli including the reader's face and picture book across SBR videos and during joint attention bids specifically. In contrast, they showed increased attention to nonsalient background stimuli compared to their neurotypical peers. These attention patterns in autistic children were associated with reduced verbal and nonverbal cognitive skills and increased symptoms associated with autism. Interestingly, positive correlations in the frequency of eye gaze between SBR and free play suggested a potential predictive value for social attention in live social interactions. CONCLUSIONS: Findings highlight the utility of SBR eye-tracking tasks in understanding underlying divergences in social engagement and joint attention between autistic and neurotypical children. This commonly practiced early childhood activity may provide insights into the relationship between social engagement and learning to reveal how such attentional patterns might influence broader developmental and educational outcomes.

Exploring early life social and executive function development in infants and risk for autism: a prospective cohort study protocol of NICU graduates and infants at risk for cerebral palsy.

BACKGROUND: Delays in early social and executive function are predictive of later developmental delays and eventual neurodevelopmental diagnoses. There is limited research examining such markers in the first year of life. High-risk infant groups commonly present with a range of neurodevelopmental challenges, including social and executive function delays, and show higher rates of autism diagnoses later in life. For example, it has been estimated that up to 30% of infants diagnosed with cerebral palsy (CP) will go on to be diagnosed with autism later in life. METHODS: This article presents a protocol of a prospective longitudinal study. The primary aim of this study is to identify early life markers of delay in social and executive function in high-risk infants at the earliest point in time, and to explore how these markers may relate to the increased risk for social and executive delay, and risk of autism, later in life. High-risk infants will include Neonatal Intensive Care Unit (NICU) graduates, who are most commonly admitted for premature birth and/or cardiovascular problems. In addition, we will include infants with, or at risk for, CP. This prospective study will recruit 100 high-risk infants at the age of 3-12 months old and will track social and executive function across the first 2 years of their life, when infants are 3-7, 8-12, 18 and 24 months old. A multi-modal approach will be adopted by tracking the early development of social and executive function using behavioural, neurobiological, and caregiver-reported everyday functioning markers. Data will be analysed to assess the relationship between the early markers, measured from as early as 3-7 months of age, and the social and executive function as well as the autism outcomes measured at 24 months. DISCUSSION: This study has the potential to promote the earliest detection and intervention opportunities for social and executive function difficulties as well as risk for autism in NICU graduates and/or infants with, or at risk for, CP. The findings of this study will also expand our understanding of the early emergence of autism across a wider range of at-risk groups.

Cognitive interventions for children with acquired brain injury: A systematic review.

This systematic review identified empirically supported evidence of effective cognitive intervention for children with Acquired Brain Injury (ABI) and included clinical practice guidelines and recommendations for intervention of attention, memory and executive functioning. Databases included: PsycARTICLES; MEDLINE; PubMed; PsycINFO; PSYCHextra; Ovid; PsychBite; CINAHL and EMBASE. Abstracts and full text articles were reviewed by two independent authors. Articles reporting on a cognitive intervention for children aged 4-19 years with a primary diagnosis of ABI were included. 25 articles were identified by both reviewers (1 00% inter-rater agreement), with the last search conducted in June 201 9. Articles were assigned to one of four categories of primary intervention: (1) Attention and Memory; (2) Executive Functioning; (3) Attention, Memory, and Executive Functioning or (4) Multi-Model Comprehensive Combined Approaches. Articles were critically appraised and level of evidence was determined according to established quality methodology criteria. Of the 25 articles evaluated, nine articles were rated Class 1, eight Class 11, and nine Class 111. One practice standard and one practice option was provided. Key suggestions included using more homogeneous samples in terms of age and injury characteristics (e.g., nature and severity of ABI, age at ABI) and incorporating long-term monitoring of outcome. Interventionalists must consider the dynamic nature of brain and cognitive development and the changing environmental needs of children.

Extending the positive bias in Williams syndrome: The influence of biographical information on attention allocation.

There is evidence that individuals with Williams syndrome (WS) show an attention bias toward positive social-perceptual (happy) faces. Research has not yet considered whether this attention bias extends beyond social-perceptual stimuli to perceptually neutral stimuli that are paired with positive (trustworthy) biographical information. Fourteen participants with WS (mean age = 21 years, 1 month) learned to associate perceptually neutral faces with trustworthy (positive), neutral, or untrustworthy (negative) biographical information, before completing a dot-probe task where the same biographical faces were presented. The performance of the WS group was compared to two typically developing control groups, individually matched to the WS individuals on chronological age and mental age, respectively. No between-group bias toward untrustworthy characters was observed. The WS group displayed a selective attention bias toward trustworthy characters compared to both control groups (who did not show such a bias). Results support previous findings that indicate WS individuals show a preference for positive social-perceptual stimuli (happy faces) at the neurological, physiological, and attentional levels. The current findings extend this work to include a "top-down" positive bias. The implications of a positive bias that extends beyond social-perceptual stimuli (or "bottom-up" processes) in this syndrome are discussed.

Perceiving and attributing intentionality in schizophrenia.

Introduction: People with schizophrenia perform poorly on theory-of-mind (ToM) tasks. They also generate less mental-state language to describe test stimuli depicting intentionality. Some of these individuals also show excessive mentalising when objective cues of intentionality are absent. We tested perceiving and attributing intentionality to resolve this paradox. Methods: 23 schizophrenia patients and 20 healthy controls completed the chasing detection task to assess perceptual sensitivity to cues of intentionality. Other tasks assessed spontaneous attributions of intentionality (irrespective of accuracy) and accurate ToM inferences. Results: Perceptual sensitivity to cues of intentionality did not differ between groups. Patients were less likely to spontaneously attribute intentionality (irrespective of accuracy) or perform ToM tasks accurately. Chasing-detection response bias, but not perceptual sensitivity, correlated with attributions of intentionality. Referential (and to less extent) persecutory ideation associated with excessive mentalising when cues of intentionality were absent. Conclusions: Intentionality can be directly perceived, independent of attributions or inferences, in people with schizophrenia. We conclude that the flow of information from intact perceptual detection to evoke spontaneous attributions of intentionality is disrupted in schizophrenia, with flow-on detrimental effects on accurate ToM reasoning. Referential/persecutory ideation motivates inappropriate mentalising when objective cues of intentionality are absent.

Adjustment and homesickness in hospitalised children: A systematic review.

Children can experience significant distress during hospitalisation, as a result of the treatment process and due to psychosocial factors impacting their adjustment to the hospital environment. Such factors can contribute to negative outcomes for the child. Despite this, limited research focus has been placed on understanding the psychosocial factors that contribute to a child's distress to inform support strategies that can improve the experience of hospitalisation across paediatric conditions. The objectives of this review were to synthesise the qualitative and quantitative literature on psychosocial factors associated with hospital adjustment and to identify risk and protective factors that influence the adjustment process. The literature search (1980 to February 2024: CINAHL / Embase / Medline / PsychINFO and Web of Science databases) identified thirty-four studies. Poor hospital adjustment, anxiety, depression and homesickness, were reported by the majority of hospitalised children. Several demographic and psychosocial factors were identified in the quantitative synthesis to contribute to poor adjustment. Child age, temperament, attachment style, past negative hospital experiences, homesickness and fear cognitions, were all associated with adjustment to the hospital environment. Homesickness was identified as a particularly understudied and important construct. Theoretical and methodological considerations are discussed, and recommendations made for future research that can further support inpatient children and their families.

Estimating the Prevalence of Autism Spectrum Disorder in New South Wales, Australia: A Data Linkage Study of Three Routinely Collected Datasets.

Routinely collected data help estimate the prevalence of autism spectrum disorder (ASD) in jurisdictions without active autism surveillance. We created a population-based cohort of 1,211,834 children born in 2002-2015 in New South Wales, Australia using data linkage. Children with ASD were identified in three datasets - disability services, hospital admissions, and ambulatory mental health data. The prevalence of ASD in the cohort was 1.3% by age 12 and prevalence at age 6 increased an average of 4.1% per year (95% Confidence Interval, 3.3%, 4.8%). Most children with ASD were identified in disability services data (87%), although data linkage identified 1,711 additional cases that were more likely female, older at first contact, and living in major cities and less disadvantaged areas.

Access and barriers to supports for children and caregivers attending public child developmental assessment services: Findings from the Sydney child neurodevelopment research registry.

Families can spend years waiting for a developmental assessment. We sought to understand supports caregivers had accessed by the time of their child's first multi-disciplinary developmental assessment, the supports caregivers wanted, and the barriers caregivers reported to accessing these supports. We also sought to understand how government funding schemes (the National Disability Insurance Scheme) and sociodemographic factors influenced access to supports. Caregivers were emailed questionnaires on sociodemographic background and intervention history prior to their child's developmental assessment at a tertiary diagnostic and assessment service. Results from 202 caregivers showed most children were receiving less than 2 hours of support each week at assessment. The most common accessed supports were from general practitioners and pediatricians. Caregivers reported behavioral therapists (41%) and psychologists (29%) as the most desired but inaccessible child supports. Half of caregivers nominated a need for parenting interventions. The most frequent barriers to accessing child supports were wait lists, finance, and knowledge. Government funding improved access to the total number of services received (from 2.7 to 5.2 different services), but for disability specific services only (e.g., speech and occupational therapy). Results highlighted disparities for families without government funding, impacting certain groups (e.g., children over 7 years) and services (e.g., mental health). Socioeconomic disadvantage, parental separation, and, surprisingly, being from a non-culturally/linguistically diverse background were associated with fewer services and more barriers. Results highlight the need to facilitate access to supports for families to align with existing recommendations.

Statistical Validation of An Automated Method for Calculating Time Domain Heart Rate Variability on The QT Dataset.

Heart rate variability measures calculated from electrocardiography recordings reflect social competence. Clinical assessments of social skills have found that reduced heart rate variability is related to differences in the development of social skills in children and increase the risk of mental disorders. Limited by widespread manual signal processing and R-peak detection in current clinical assessments, most literature reports only short-term baseline studies, with fewer studies reporting social interaction settings with prolonged recording. There is an urgent need for an automated physiological signal processing toolbox to detect R-peaks and perform heart rate variability measurements in social settings. This paper proposes a modified automated Neurokit2 toolbox with signal processing procedures similar to the MindWare software that requires manual inspection of R-peak locations. We calculate time domain heart rate variability metrics from the publicly available QT database by PhysioNet collected at resting states and under stress tests, mimicking social interaction stress scenarios. Statistical analysis conveys that heart rate variability metrics calculation applying both signal processing approaches using the Neurokit2 toolbox are statistically equivalent in comparison to the hand-labelled R-peaks from the QT database (n= 10 in the normal sinus rhythm group, and n= 6 in the ST Change group). Such validation results are crucial for the adoption of automated toolboxes for heart rate variability measures in social interaction assessments, where more movement and mood changes of participants are expected.Clinical Relevance- This contributes to the body of evidence of the reliability of the Neurokit2 toolbox for automatic cleaning of prolonged cardiac electrophysiological signals and calculation of heart rate variability in time-domain characterization in social interaction stress assessment.

The English Version of the Schema Inventory for Children: Psychometric Evaluation of a Measure of Early Maladaptive Schemas in a Primary School-Aged Sample.

Early maladaptive schemas (EMSs) are proposed to be maladaptive ways of thinking and feeling that develop from adverse experiences and basic needs not being met in childhood or adolescence. Once developed, EMSs increase vulnerability to psychopathology. Psychometric evaluations of EMS measures in children are scarce. This study aimed to evaluate the psychometric properties of the English version of the Schema Inventory for Children (SIC) in a community sample of youth aged 8 to 13 years. The SIC and measures of positive and negative automatic thoughts, social phobia symptoms, and depressed mood were administered to participants. Although a correlated 11-factor model was expected for the SIC, the optimal factor structure was a correlated six-factor model. EMS subscales corresponding to these six factors had acceptable internal consistency, and they had positive associations with the measures of negative automatic thoughts, social phobia symptoms, and depressive mood, as well as negative associations with the measure of positive automatic thoughts. These results indicate that EMSs in children may not be as differentiated as they are in adults. The results provide evidence for the reliability and validity of the English version of the SIC, justifying its use in contexts requiring the assessment of EMSs in children.

Diagnostic delay in children with neurodevelopmental conditions attending a publicly funded developmental assessment service: findings from the Sydney Child Neurodevelopment Research Registry.

OBJECTIVES: Early developmental assessment is crucial for effective support and intervention. This study examined factors that contribute to (a) older child age when caregivers first became concerned about their child's development and (b) older child age at the point of entry into developmental and diagnostic assessment. We also quantified how factors contributed to risk of children not receiving an assessment by 5 years and considered the acceptability of electronic data capture for families. DESIGN: This cross-sectional study collected information about caregiver developmental concerns, family history and child characteristics. SETTING: Children and families entered a large, publicly funded hospital-based paediatric developmental assessment service. PARTICIPANTS: Consecutively enrolled children (N=916) aged 6 months to 17 years with neurodevelopmental concerns and their caregivers. MAIN OUTCOMES AND MEASURES: A developmental history questionnaire completed by caregivers. RESULTS: The average age that caregivers identified developmental concerns was 3.0 years of age but the average age of a receiving a developmental assessment was 6.6 years. Only 46.4% of children received a diagnostic assessment by 5 years of age, even though 88.0% of caregivers were concerned about their child's development by that age. Parental age, relationship status, education level, prior use of support services and being from a culturally and linguistically diverse background contributed to age at identification of concern, age at diagnostic assessment and the likelihood of receiving a diagnostic assessment by 5 years. Electronic data capture had high acceptability, with 88.2% of caregivers reporting a preference for electronic completion of questionnaires. CONCLUSIONS: The study shows a substantial delay in diagnostic assessments that leaves most vulnerable children without an assessment by school age and highlights contributors to delays. These delays highlight the complexity of delivering early intervention and support policies that rely on swift and appropriate developmental assessment to vulnerable families.

Mental health concerns in children with neurodevelopmental conditions attending a developmental assessment service.

Children with neurodevelopmental conditions (NDCs), such as autism and attention-deficit/hyperactivity disorder (ADHD), frequently experience co-occurring mental health concerns. Little research has examined mental health symptoms in children attending developmental assessment services. This study profiled mental health symptoms in children with NDCs attending a hospital-based diagnostic service for their first diagnostic and developmental assessment. Participants were 232 children aged 1.96-17.51 years. Mental health concerns were assessed using the Child Behavior Checklist (CBCL), a caregiver-rated, questionnaire-based assessment of behavioural and emotional difficulties. Subclinical or clinically elevated internalising, externalising and total scores on the CBCL were reported in approximately 48% of preschool and 61% of school-age children. These increased prevalence rates, using the same cutoff scores, remained after excluding items specifically relating to neurodevelopmental concerns (36% preschool; 37% school-age children). More school-aged females reported elevated internalising problems, relative to males (67 % vs 48 %). The number of diagnoses impacted symptoms, with children who received two or more DSM-5 diagnoses showing a greater rate of subclinical or clinically elevated scores, relative to children who received one DSM-5 diagnosis. Our findings demonstrate that children attending developmental assessment services have considerable mental health needs. It is critical that mental health concerns are identified and addressed in children when they first present to developmental assessment services, and that service providers are equipped to provide appropriate resources and pathways to ongoing care.

Understanding the vocational functioning of autistic employees: the role of disability and mental health.

PURPOSE: Employment rates for autistic people are low, despite increasing employment-focused programmes. Given the reported complexities for autistic people in finding and keeping work and flourishing there, further exploration is needed to understand how best to help employers accommodate autistic employees. MATERIAL AND METHODS: We assessed 88 employed autistic adults, without comorbid intellectual disability and examined whether self-reported disability and mental health symptoms were associated with two measures of vocational functioning: disability days off work and vocational disability. RESULTS: Nearly half (47%) reported at least one disability day absence in the previous month. Autism severity and IQ were not associated with either measure of vocational functioning. Greater disability and higher mental health symptoms were associated with both types of vocational functioning. However, the associations of anxiety and stress with both vocational outcomes were attenuated to null in a multivariable model. Disability (B = 6.74, p = 0.009; B = 1.18, p < 0.001) and depression (B = 4.46, p = 0.035; B = 1.01, p = 0.049) remained independently associated with both outcomes. CONCLUSIONS: Clinicians and vocational support programmes addressing modifiable factors may need to focus on addressing mental health comorbidities, specifically depression rather than anxiety, or core features of autism to improve vocational outcomes for autistic people. Implications for RehabilitationIndividual-level interventions that reduce disablement, particularly in social areas, and depressive symptoms as a way of reducing days off work and improving workplace activities in autistic employees are recommended.Organisations can accommodate autistic employees by encouraging use of mental health programmes or looking at how the workplace environment can be adapted to limit social disability.

Quality and accessibility of written development assessment reports provided to caregivers in a publicly funded child developmental assessment service.

LAY ABSTRACT: Despite long wait times, public paediatric developmental assessment services remain crucial for assessment of children. Assessment is a critical opportunity to guide the placement of supports to improve outcomes. There is little research examining how clinical assessment services conduct their assessments, present results and write reports to families. This study examined 85 reports provided to caregivers at a developmental assessment service. Reports were evaluated for whether they (1) addressed caregiver perceived needs, (2) used available data to provide appropriate information about child needs, (3) provided recommendations that were actionable and specific to needs, (4) had appropriate readability levels and (5) followed existing autism assessment guidelines. Findings showed clinicians were more focused on autism diagnostic needs while caregivers were more focused on non-diagnostic needs. Recommendations related to autism diagnoses were actionable, but they rarely addressed comorbidities such as cognitive impairments or mental health. For instance, only 13% of reports contained recommendations for conditions other than autism spectrum disorder, despite 61% of the population receiving two or more diagnoses. Reports largely followed autism assessment guidelines, but the language used was more complex for families than recommended. Recommendations for future practice are provided so that consideration may be given to how to improve the quality and effectiveness of reports for families attending services.

Burden of paediatric hospitalisations to the health care system, child and family: a systematic review of Australian studies (1990-2022).

Background: Paediatric hospitalisations represent a significant cost to the health system and cause significant burden to children and their families. Understanding trends in hospitalisation costs can assist with health planning and support strategies across stakeholders. The objective of this systematic review is to examine the trends in costs and burden of paediatric hospitalisations in Australia to help inform policy and promote the well-being of children and their families. Methods: Electronic data sources (Embase, Medline, Web of Science, PSYCH-Info, CINAHL and Scopus) were searched from 1990 until December 2022. Any quantitative or qualitative studies conducted in Australian tertiary hospitals were included in the review. Eligible studies were those that included paediatric (<18 years) hospitalisations and reported on economic and/or non-economic costs for the child, family unit and/or health system. Study quality and risk of bias for each study were assessed with the Joanna Briggs Critical Appraisal Tools. We present a summary of the findings of the hospitalisation burden across major diagnostic admission categories and for the child and family unit. The systematic review was registered with Prospero (ID: CRD42021276202). Findings: The review summarises a total of 88 studies published between 1990 and December 2022. Overall, the studies identified that paediatric hospitalisations incur significant financial costs, which have not shown significant reductions over time. In-patient direct hospital costs varied depending on the type of treatment and diagnostic condition. The costs per-case were found to range from just below AUD$2000 to AUD$20,000 or more. The financial burden on the family unit included loss of productivity, transport and travel costs. Some studies reported estimates of these costs upward of AUD$500 per day. Studies evaluating 'hospital in the home' options identified significant benefits in reducing hospitalisations and costs without compromising care. Interpretation: Increasing focus on alternative models of care may help alleviate the significant costs associated with paediatric hospitalisation. Funding: This research was supported by Hospitals United for Sick Kids (formerly Curing Homesickness).

Telehealth assessment of autism in preschoolers using the TELE-ASD-PEDS: A pilot clinical investigation.

PURPOSE: Appropriate early intervention is beneficial but dependent on accurate and timely diagnoses. This has been affected by long waiting lists for face-to-face clinical services, in part due to pandemic lockdowns, with telehealth introduced in many services to continue clinical services. This pilot clinical study investigated the feasibility of integrating a specially-designed telepractice autism assessment tool into a tertiary diagnostic service. METHOD: Eighteen boys (2;4-5;1) participated in the study. Assessment was undertaken as per standard practice (parent interview, questionnaires, review of reports), with an additional telepractice assessment, included in place of face-to-face assessment, to provide clinicians with an observation of the children's communication, behaviours, and interests. Ten parents provided feedback via semi-structured interviews. RESULT: The TELE-ASD-PEDS was a feasible assessment tool in terms of administration, clinical experience, and information gained through the assessment process. Parents reported mostly positive experiences of the TELE-ASD-PEDS and made suggestions for improvements for future use of this tool. CONCLUSION: It is possible to obtain useful information about a child's autism-specific behaviours using the activities in the TELE-ASD-PEDS. This information can be combined with clinical history from parents using the DSM-5 framework to provide a gold standard assessment for autism.

Designing an App for Parents and Caregivers to Promote Cognitive and Socioemotional Development and Well-being Among Children Aged 0 to 5 Years in Diverse Cultural Settings: Scientific Framework.

Recent years have seen remarkable progress in our scientific understanding of early childhood social, emotional, and cognitive development, as well as our capacity to widely disseminate health information by using digital technologies. Together, these scientific and technological advances offer exciting opportunities to deliver high-quality information about early childhood development (ECD) to parents and families globally, which may ultimately lead to greater knowledge and confidence among parents and better outcomes among children (particularly in lower- and middle-income countries). With these potential benefits in mind, we set out to design, develop, implement, and evaluate a new parenting app-Thrive by Five-that will be available in 30 countries. The app will provide caregivers and families with evidence-based and culturally appropriate information about ECD, accompanied by sets of collective actions that go beyond mere tips for parenting practices. Herein, we describe this ongoing global project and discuss the components of our scientific framework for developing and prototyping the app's content. Specifically, we describe (1) 5 domains that are used to organize the content and goals of the app's information and associated practices; (2) 5 neurobiological systems that are relevant to ECD and can be behaviorally targeted to potentially influence social, emotional, and cognitive development; (3) our anthropological and cultural framework for learning about local contexts and appreciating decolonization perspectives; and (4) our approach to tailoring the app's content to local contexts, which involves collaboration with in-country partner organizations and local and international subject matter experts in ECD, education, medicine, psychology, and anthropology, among others. Finally, we provide examples of the content that was incorporated in Thrive by Five when it launched globally.

Developing Culturally Appropriate Content for a Child-Rearing App to Support Young Children's Socioemotional and Cognitive Development in Afghanistan: Co-Design Study.

BACKGROUND: Optimal child-rearing practices can help mitigate the consequences of detrimental social determinants of health in early childhood. Given the ubiquity of personal digital technologies worldwide, the direct delivery of evidence-based information about early childhood development holds great promise. However, to make the content of these novel systems effective, it is crucial to incorporate place-based cultural beliefs, traditions, circumstances, and value systems of end users. OBJECTIVE: This paper describes the iterative approach used to develop the Thrive by Five child-rearing app in collaboration with Afghan parents, caregivers (eg, grandparents, aunts, and nannies), and subject matter experts (SMEs). We outline how co-design methodologies informed the development and cultural contextualization of content to meet the specific needs of Afghan parents and the content was tested and refined in collaboration with key Afghan stakeholders. METHODS: The preliminary content was developed based on a comprehensive literature review of the historical and sociocultural contexts in Afghanistan, including factors that influence child-rearing practices and early childhood development. After an initial review and refinement based on feedback from SMEs, this content was populated into a beta app for testing. Overall, 8 co-design workshops were conducted in July and August 2021 and February 2022 with 39 Afghan parents and caregivers and 6 SMEs to collect their feedback on the app and its content. The workshops were audio recorded and transcribed; detailed field notes were taken by 2 scribes. A theoretical thematic analysis using semantic codes was conducted to inform the refinement of existing content and development of new content to fulfill the needs identified by participants. RESULTS: The following 4 primary themes were identified: child-rearing in the Afghan sociocultural context, safety concerns, emotion and behavior management, and physical health and nutrition. Overall, participants agreed that the app had the potential to deliver valuable information to Afghan parents; however, owing to the volatility in the country, participants recommended including more activities that could be safely done indoors, as mothers and children are required to spend most of their time at home. Additionally, restrictions on public engagement in music required the removal of activities referencing singing that might be performed outside the home. Further, activities to help parents reduce their children's screen time, promote empathy, manage emotions, regulate behavior, and improve physical health and nutrition were requested. CONCLUSIONS: Direct engagement with Afghan parents, caregivers, and SMEs through co-design workshops enabled the development and refinement of evidence-based, localized, and contextually relevant child-rearing activities promoting healthy social, emotional, and cognitive development during the first 5 years of children's lives. Importantly, the content was adapted for the ongoing conflict in Afghanistan with the aim of empowering Afghan parents and caregivers to support their children's developmental potential despite the security concerns and situational stressors.

The Importance of Experimental Investigation of the CNS Oxytocin System.

This chapter provides an overview of the oxytocinergic system and its role in social behavior. We first consider the relationship between oxytocin and social behavior in neurotypical individuals, focusing on studies that have looked at effects of intranasal oxytocin treatment, as well as research investigating the genetic and epigenetic mechanisms associated with individual differences in social behavior. We then outline the proposed role of the oxytocinergic system in autism spectrum disorder and Williams syndrome, two neurodevelopmental disorders where a dysfunctional oxytocinergic system is thought to lead to difficulties in social behavior. Given the contrasting social phenotypes of these disorders, they provide an intriguing comparison through which we can better understand the role of the oxytocinergic system in social behavior. Finally, we consider how future research can best harness the potential of oxytocin, both by addressing measurement and administration issues inherent in many studies, and by developing our understanding of the oxytocinergic system so we are better able to identify the people who are likely to benefit from oxytocin treatment, and intervene at the right time.
