Preventing postnatal depression in new mothers using telephone peer support: protocol for the DAISY (Depression and AnxIety peer Support studY) multi-centre randomised controlled trial.

INTRODUCTION: Postnatal depression affects up to one in six new mothers in Australia each year, with significant impacts on the woman and her family. Prevention strategies can be complicated by a woman's reluctance to seek professional help. Peer support is a promising but inadequately tested early intervention. Very few trials have reported on the efficacy of peer support in the perinatal period and no study has been undertaken in Australia. We will explore if proactive telephone-based peer (mother-to-mother) support, provided to women identified as being at high risk of postnatal depression, impacts on clinically significant depressive symptomatology at 6 months postpartum. METHODS AND ANALYSIS: This is a protocol for a single-blinded, multi-centre, randomised controlled trial conducted in Melbourne, Australia. Eligible women will be recruited from either the postnatal units of two maternity hospitals, or around 4 weeks postpartum at maternal and child health centres within two metropolitan council areas. A total of 1060 (530/group) women will be recruited and randomly allocated (1:1 ratio) to either-usual care, to receive the standard community postpartum services available to them, or the intervention group, to receive proactive telephone-based support from a peer volunteer for 6 months, in addition to standard community services. PRIMARY OUTCOME: clinically significant depressive symptomatology at 6 months postpartum as measured using the Edinburgh Postnatal Depression Scale. SECONDARY OUTCOMES: symptoms of anxiety and/or stress, health-related quality of life, loneliness, perception of partner support, self-rated parenting, child health and development, infant feeding and health service use. The cost-effectiveness of the intervention relative to standard care will also be assessed. ETHICS AND DISSEMINATION: Ethics approval has been obtained from La Trobe University, St. Vincent's Hospital, the Royal Women's Hospital, Northern Health, Victorian Department of Health and Human Services and Victorian Department of Education and Training. Written informed consent will be obtained from all participants before randomisation. Trial results will be disseminated through peer-reviewed publications, conference presentations and a higher degree thesis.

Prevalence of toddlers meeting 24-hour movement guidelines and associations with parental perceptions and practices.

OBJECTIVES: Whether toddlers (1-2 years) meet 24-hour Movement Guidelines and how parental practices and perceptions are related to compliance are uncertain. This study: a) estimated the proportion of toddlers meeting individual and combined movement guidelines; and b) examined associations between parental perceptions/practices and toddlers' compliance with movement guidelines. DESIGN: Cross-sectional study. METHODS: Australian parents self-reported their parenting practices/perceptions (routines, co-participation, restrictions, concerns, knowledge) and toddlers' movement behaviours in the baseline assessment of Let's Grow (n=1145), a randomised controlled trial. The World Health Organization's Guidelines on Physical Activity, Sedentary Behaviour, and Sleep for children under 5 years were used to estimate the prevalence of compliance with individual and combined movement guidelines. Logistic models assessed cross-sectional associations. RESULTS: The prevalence of meeting guidelines was 30.9% for screen time, 82.3% for sleep, 81.6% for physical activity, 20.1% for combined, and 2.1% meeting none. Parents' knowledge of the guidelines, fewer concerns and more favourable restrictions concerning movement behaviours were associated with greater compliance with individual and combined movement guidelines. Routines for screen time and for combined behaviours were associated with adherence to their respective guidelines. Less co-participation in screen time and more co-participation in physical activity were associated with greater compliance with the relevant guidelines. CONCLUSIONS: Given only 20% of toddlers met all guidelines, strategies early in life to establish healthy movement behaviours, especially screen time, are needed. Future studies could target the parental practices/perceptions identified in this study to support toddlers with optimal sleep and physical activity and reduced screen time.

Family Functioning in Children With ADHD and Subthreshold ADHD: A 3-Year Longitudinal Study.

OBJECTIVE: To compare family functioning over time for elementary school children with Attention-Deficit/Hyperactivity Disorder (ADHD; N = 179) and subthreshold ADHD (ST-ADHD; N = 86), to children without ADHD (Control; N = 212). METHOD: ADHD was assessed using the Conners 3 ADHD Index and Diagnostic Interview Schedule for Children IV. At baseline, 18-month follow-up and 36-month follow-up, parents completed measures assessing a range of family functioning domains. RESULTS: At baseline, the ADHD group reported higher psychological distress, less parenting self-efficacy, less parenting consistency, and more stressful life events; and both groups reported poorer family quality of life (QoL) and greater parenting anger. Trajectories were largely similar to controls (i.e., stable over time), but unlike controls, ADHD and ST-ADHD groups showed lessening parent-partner support and parenting warmth, respectively; and both groups showed worsening aspects of family QoL. CONCLUSION: Families of children with ADHD and ST-ADHD report persistently poor or worsening family functioning; highlighting a need for tailored psycho-social supports.

Social and emotional wellbeing of Aboriginal and Torres Strait Islander peoples in Aboriginal controlled social housing.

BACKGROUND: Little is known about the wellbeing and aspirations of Aboriginal and Torres Strait Islander peoples living in social housing. Aboriginal and Torres Strait Islander peoples living in social housing face common social housing challenges of low income, higher incidence of mental health issues and poorer health along with specific challenges due to the impacts of colonisation and its ongoing manifestations in racism and inequity. A greater understanding of social and emotional wellbeing needs and aspirations is essential in informing the provision of appropriate support. METHODS: Surveys of social and emotional wellbeing (SEWB) were completed by 95 Aboriginal people aged 16 years and older living in Aboriginal Housing Victoria social housing in 2021. The survey addressed a range of domains reflecting social and emotional wellbeing, as defined by Aboriginal and Torres Strait Islander peoples. RESULTS: Most respondents demonstrated a strong sense of identity and connection to family however 26% reported having 6 or more health conditions. Ill health and disability were reported to be employment barriers for almost a third of people (32%). Improving health and wellbeing (78%) was the most cited aspiration. Experiences of racism and ill health influenced engagement with organisations and correspondingly education and employment. CONCLUSION: Strong connections to identity, family and culture in Aboriginal peoples living in social housing coexist along with disrupted connections to mind, body and community. Culturally safe and appropriate pathways to community services and facilities can enhance these connections. Research aimed at evaluating the impact of strengths-based interventions that focus on existing strong connections will be important in understanding whether this approach is effective in improving SEWB in this population. TRIAL REGISTRATION: This trial was retrospectively registered with the ISRCTN Register on the 12/7/21 with the study ID:ISRCTN33665735.

Categorical and dimensional approaches to the developmental relationship between ADHD and irritability.

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) and irritability commonly co-occur, and follow similar developmental trajectories from childhood to adolescence. Understanding of the developmental relationship between these co-occurrences is limited. This study provides a longitudinal assessment of how ADHD diagnostic status and symptom patterns predict change in irritability. METHODS: A community sample of 337 participants (45.2% ADHD), recruited for the Childhood Attention Project, completed the Affective Reactivity Index (ARI) to measure irritability at baseline (mean age 10.5 years) and follow-up after 18-months. Latent change score models were used to assess how (a) baseline ADHD vs. control group status, (b) baseline symptom domain (inattention, hyperactivity-impulsivity) and (c) longitudinal change in ADHD symptom severity predicted change in irritability. RESULTS: Irritability was significantly higher among the ADHD group than controls; however, change in irritability over time did not differ between groups. When assessed across the entire cohort, change in irritability was predicted by higher symptom count in the hyperactive-impulsive domain, but not the inattentive domain. Greater declines in ADHD symptoms over time significantly predicted greater declines in irritability. Baseline ADHD symptom severity was found to significantly predict change in irritability; however, baseline irritability did not significantly predict change in ADHD symptoms. CONCLUSIONS: ADHD symptoms-particularly hyperactive-impulsive symptoms-predict the degree and trajectory of irritability during childhood and adolescence, even when symptoms are below diagnostic thresholds. The use of longitudinal, dimensional and symptom domain-specific measures provides additional insight into this relationship.

Family Bonds with Pets and Mental Health during COVID-19 in Australia: A Complex Picture.

The COVID-19 pandemic has drawn attention to the health-promoting features of human-animal relationships, particularly for families with children. Despite this, the World Health Organization's (1986) Ottawa Charter remains human-centric. Given the reciprocal health impacts of human-animal relationships, this paper aims to (i) describe perceived pet-related benefits, worries, and family activities; and to (ii) examine differences in perceived benefits, worries, and activities for parents and children with and without clinical mental health symptoms. We recruited 1034 Australian parents with a child < 18 years and a cat or dog via a national online survey between July and October 2020. Most parents reported their pet was helpful for their own (78%) and their child's mental health (80%). Adjusted logistic regression revealed parents with clinical psychological distress were 2.5 times more likely to be worried about their pet's care, well-being, and behaviour (OR = 2.56, p < 0.001). Clinically anxious children were almost twice as likely to live in a family who engages frequently in pet-related activities (e.g., cooked treats, taught tricks, OR = 1.82, p < 0.01). Mental health and perceived benefits of having a pet were not strongly associated. Data support re-framing the Ottawa Charter to encompass human-animal relationships, which is an often-neglected aspect of a socioecological approach to health.

Rural primary care workforce views on trauma-informed care for parents experiencing complex trauma: A descriptive study.

BACKGROUND: An important service system for rural parents experiencing complex trauma is primary health care. AIM: To investigate workforce knowledge, attitudes and practices, and barriers and enablers to trauma-informed care in rural primary health care. MATERIAL & METHODS: This study used a descriptive, cross-sectional design. It involved an on-line survey conducted in 2021 in rural Victoria, Australia. Participants were the primary health care workforce. The main outcome measures were study-developed and included, a 21-item Knowledge, Attitudes and Practices tool, a 16-item Barriers and Enablers to Trauma-Informed Care Implementation tool, and three open-ended questions. RESULTS: The 63 respondents were from community health (n = 40, 63%) and child and family services (n = 23, 37%). Many (n = 43, 78%) reported undertaking trauma-informed care training at some point in their career; with 32% (n = 20) during higher education. Respondents self-rated their knowledge, attitudes and practices positively. Perceived enablers were mainly positioned within the service (e.g. workforce motivation and organisational supports) and perceived barriers were largely external structural factors (e.g. availability of universal referral pathways, therapeutic-specific services). Open-ended comments were grouped into four themes: (1) Recognition and understanding; (2) Access factors; (3) Multidisciplinary and collaborative approaches; and (4) Strengths-based and outcome-focused approaches. DISCUSSION & CONCLUSION: Primary health care is an important driver of population health and well-being and critical in rural contexts. Our findings suggest this sector needs a rural trauma-informed care implementation strategy to address structural barriers. This also requires policy and system development. Long-term investment in the rural workforce and primary care service settings is essential to integrate trauma-informed care.

Longitudinal developmental trajectories of inhibition and white-matter maturation of the fronto-basal-ganglia circuits.

Response inhibition refers to the cancelling of planned (or restraining of ongoing) actions and is required in much of our everyday life. Response inhibition appears to improve dramatically in early development and plateau in adolescence. The fronto-basal-ganglia network has long been shown to predict individual differences in the ability to enact response inhibition. In the current study, we examined whether developmental trajectories of fiber-specific white matter properties of the fronto-basal-ganglia network was predictive of parallel developmental trajectories of response inhibition. 138 children aged 9-14 completed the stop-signal task (SST). A subsample of 73 children underwent high-angular resolution diffusion MRI data for up to three time points. Performance on the SST was assessed using a parametric race modelling approach. White matter organization of the fronto-basal-ganglia circuit was estimated using fixel-based analysis. Contrary to predictions, we did not find any significant associations between maturational trajectories of fronto-basal-ganglia white matter and developmental improvements in SST performance. Findings suggest that the development of white matter organization of the fronto-basal-ganglia and development of stopping performance follow distinct maturational trajectories.

Does place matter in the implementation of an evidence-based program policy in an Australian place-based initiative for children?

Policy-mandated requirements for use of evidence-based programs (EBP) in place-based initiatives are becoming more common. Little attention has been paid to the geographic aspects of uneven market development and urbanicity in implementing EBPs in large place-based initiatives. The aim of this study was to explore geographic variation in knowledge, attitudes, and experiences of service providers who implemented an EBP policy in Australia's largest place-based initiative for children, Communities for Children. A cross-sectional online survey of Communities for Children service providers was conducted in 2018-2019, yielding 197 participants from all of Australia's eight states and territories. Relationships between two measures of 'place' (thick and thin market states; urbanicity: urban, regional and remote) and study-designed measures of knowledge, attitudes, and implementation experiences were analyzed using adjusted logistic and multinomial regressions. Participants from thin market states (outside the Eastern Seaboard) were more resistant to the policy and experienced greater implementation challenges than those from thick market states (Eastern Seaboard). Regional participants reported greater knowledge about EBPs but experienced greater dissatisfaction and implementation challenges with the policy than both urban and remote participants. Our study found that place does matter when implementing EBPs in a place-based initiative.

Parent and child mental health during COVID-19 in Australia: The role of pet attachment.

Restrictions, social isolation, and uncertainty related to the global COVID-19 pandemic have disrupted the ways that parents and children maintain family routines, health, and wellbeing. Companion animals (pets) can be a critical source of comfort during traumatic experiences, although changes to family routines, such as those caused by COVID-19, can also bring about challenges like managing undesirable pet behaviours or pet-human interactions. We aimed to examine the relationship between pet attachment and mental health for both parents and their children during the COVID-19 pandemic in Australia. A total of 1,034 parents living with a child under 18 years and a cat or dog completed an online cross-sectional survey between July and October 2020. Path analysis using multivariate linear regression was conducted to examine associations between objective COVID-19 impacts, subjective worry about COVID-19, human-pet attachment, and mental health. After adjusting for core demographic factors, stronger pet-child attachment was associated with greater child anxiety (parent-reported, p < .001). Parent-pet attachment was not associated with self-reported psychological distress (p = .42), however, parents who reported a strong emotional closeness with their pet reported greater psychological distress (p = .002). Findings highlight the role of pets during times of change and uncertainty. It is possible that families are turning to animals as a source of comfort, during a time when traditional social supports are less accessible. Alternatively, strong pet attachment is likely to reflect high levels of empathy, which might increase vulnerability to psychological distress. Longitudinal evidence is required to delineate the mechanisms underpinning pet attachment and mental health.

Maternal and Child Health Nursing education before and during COVID-19: An exploratory descriptive study.

BACKGROUND: Major disruptions to higher education during COVID-19 resulted in a rapid shift to online learning and associated adaptations to teaching and assessment practices, including for postgraduate programs requiring practical skill development such as nursing and midwifery. Educator perspectives of this transition have not been widely studied. PURPOSE: This qualitative descriptive study aimed to describe Australian postgraduate Maternal, Child and Family Health nurse educators' perceptions of COVID-19 impacts on student knowledge of theory and practice, and lessons learned through their responses. METHOD: Semi-structured interviews were reflexively thematically analyzed. RESULTS: All participants recognized struggles, opportunities and innovations within three key themes: "We've learned how to be flexible": Grappling with COVID-safe teaching and assessment; "Chat rooms and Zoomland": Learning in a virtual community; and "We've had a few struggles": Clinical placement tensions. Educators described a sense of uncertainty, increased flexibility, opportunities for change and new ways of connecting. They adapted by developing new online resources and broadening clinical practicum and assessment requirements to address new practice approaches including telehealth. CONCLUSIONS: Rapidly changing practice requirements and concerns about risk of disease transfer between workplace and placement venues restricted placement opportunities. Educators learned and incorporated new skills and strategies into their teaching, while aiming to meet professional expectations and maintain quality of education. Some strategies are likely to be maintained for future education programs.

Disparities in postnatal depression and anxiety screening: Results from a cross sectional survey of Maternal and Child health nurses in Victoria, Australia.

OBJECTIVES: To describe Maternal and Child Health nurses' self-reported knowledge of, and attitude toward screening for postnatal depression and anxiety, and identify factors which impact screening in line with recommended guidelines. METHODS: A population-based, cross-sectional study of all Maternal and Child Health nurses in Victoria, Australia. Data were collected in 2019 through an online survey designed to fit a Knowledge, Attitude and Practice framework. Descriptive analyses were conducted to describe participant characteristics, self-reported knowledge, attitude, and practices. Bivariate and multivariate regression analysis were performed to evaluate associations between screening practices and nurses' attitude toward screening and a range of sociodemographic variables. RESULTS: Two hundred and eighteen Maternal and Child Health nurses participated in the study. Participants viewed screening as an important part of their role and screened all mothers at least once in the first 12 month postpartum. <35% routinely did so more than once in the first 12 months postpartum, and 31% were able to adhere to the recommended use of psychosocial assessments as part of their screening practice. After adjusting for confounding factors, nurses practicing in communities with greater socio-economic advantage were significantly more likely to conduct psychosocial assessments (aOR 3.93, 95% CI 1.47-10.49) and screen more than once (aOR 2.91, 95% CI 1.18-7.13), compared to nurses who worked in disadvantaged communities. CONCLUSION: Place-based inequities in nurses' screening practices serve to widen the gap in health outcomes between advantaged and disadvantages mothers. Policy and practice strategies must consider the systematic challenges that contribute to this phenomenon and embed place-based strategies which address them.

A review of Australian Government funding of parenting intervention research.

OBJECTIVES: Parenting is central to children's optimal development and accounts for a substantial proportion of the variance in child outcomes, including up to 40% of child mental health. Parenting is also one of the most modifiable, proximal, and direct factors for preventing and treating a range of children's problems and enhancing wellbeing. To determine the effectiveness of new approaches to parenting intervention, and to evaluate how to optimise reach and uptake, sufficient funding must be allocated for high quality research. METHOD: We reviewed funding awarded by the National Health and Medical Research Council (NHMRC) and Australian Research Council (ARC) for parenting intervention research during 2011-2020. RESULTS: Parenting intervention research received 0.25% of the NHMRC and ARC research budgets. CONCLUSIONS: There is a substantial mismatch between the funding of parenting intervention research and the impact of improved parenting on short- and long-term child outcomes. To rectify this, it is critical that Australian Government funding schemes include parenting interventions as priority areas for funding. IMPLICATIONS FOR PUBLIC HEALTH: Changes in allocation of funding to parenting research will support the establishment of evidence for the effective development, implementation and dissemination of parenting interventions to maximise health outcomes for children and their families.

Protocol for the Let's Grow randomised controlled trial: examining efficacy, cost-effectiveness and scalability of a m-Health intervention for movement behaviours in toddlers.

INTRODUCTION: Despite being an important period for the development of movement behaviours (physical activity, sedentary behaviour and sleep), few interventions commencing prior to preschool have been trialled. The primary aim of this trial is to assess the 12-month efficacy of the Let's Grow mHealth intervention, designed to improve the composition of movement behaviours in children from 2 years of age. Let's Grow is novel in considering composition of movement behaviours as the primary outcome, using non-linear dynamical approaches for intervention delivery, and incorporating planning for real-world implementation and scale-up from its inception. METHODS AND ANALYSIS: A randomised controlled trial will test the effects of the 12-month parental support mHealth intervention, Let's Grow, compared with a control group that will receive usual care plus electronic newsletters on unrelated topics for cohort retention. Let's Grow will be delivered via a purpose-designed mobile web application with linked SMS notifications. Intervention content includes general and movement-behaviour specific parenting advice and incorporates established behaviour change techniques. Intervention adherence will be monitored by app usage data. Data will be collected from participants using 24-hour monitoring of movement behaviours and parent report at baseline (T0), mid-intervention (T1; 6 months post baseline), at intervention conclusion (T2; 12 months post baseline) and 1-year post intervention (T3; 2 years post baseline). The trial aims to recruit 1100 families from across Australia during 2021. In addition to assessment of efficacy, an economic evaluation and prospective scalability evaluation will be conducted. ETHICS AND DISSEMINATION: The study was approved by the Deakin University Human Ethics Committee (2020-077). Study findings will be disseminated through publication in peer-reviewed journals, presentation at scientific and professional conferences, and via social and traditional media. TRIAL REGISTRATION NUMBER: ACTRN12620001280998; U1111-1252-0599.

Using participatory action research to co-design perinatal support strategies for Aboriginal and Torres Strait Islander parents experiencing complex trauma.

PROBLEM & BACKGROUND: Support is important for all parents but critical for those experiencing complex trauma. The The Healing the Past by Nurturing the Future project uses participatory action research to co-design effective perinatal support for Aboriginal and Torres Strait Islander parents. AIM: This research aims to identify and refine culturally appropriate support strategies for Aboriginal and Torres Strait Islander parents experiencing complex trauma. DESIGN: We presented our synthesised eight parent support goals and 60 strategies, collated from Elder and parent focus groups, previous participatory workshops, and evidence reviews, for discussion at a stakeholder workshop. Stakeholder perspectives were captured using a three-point agreement activity and, self- and scribe-recorded comments. Aboriginal and non-Aboriginal researchers analysised the qualitative data, to identify core factors which might facilitate or help enact the parenting related goals. FINDINGS: Overall, stakeholders (n = 37) strongly endorsed all eight goals. Workshop attendees (57% Aboriginal) represented multiple stakeholder roles including Elder, parent and service provider. Four core factors were identified as crucial for supporting parents to heal from complex trauma: Culture (cultural traditions, practices and strengths), Relationality (family, individual, community and services), Safety (frameworks, choice and control) and Timing (the right time socio-emotionally and stage of parenting). DISCUSSION: Context-specific support tailored to the Culture, Relationality, Safety, and Timing needs of parents is essential. These four factors are important elements to help enact or facilitate parenting support strategies. CONCLUSION: Further work is now required to develop practical resources for parents, and to implement and evaluate these strategies in perinatal care to address cumulative and compounding cycles of intergenerational trauma.

Place-based approaches to improve health and development outcomes in young children: A scoping review.

This scoping review examines the strength of evidence for the effectiveness of public policy-led place-based initiatives designed to improve outcomes for disadvantaged children, their families and the communities in which they live. Study designs and methods for evaluating such place-based initiatives were assessed, along with the contexts in which initiatives were implemented and evaluated. Thirty-two reports relating to 12 initiatives were included. Eleven initiatives used a quasi-experimental evaluation to assess impact, although there were considerable design variations within this. The remaining initiative used a pre- and post- evaluation design. Place-based initiatives by definition aim to improve multiple and interrelated outcomes. We examined initiatives to determine what outcomes were measured and coded them within the five domains of pregnancy and birth, child, parent, family and community. Across the 83 outcomes reported in the 11 studies with a comparison group, 30 (36.4%) demonstrated a positive outcome, and all but one initiative demonstrated a positive outcome in at least one outcome measure. Of the six studies that examined outcomes more than once post baseline, 10 from 38 outcomes (26.3%) demonstrated positive sustained results. Many initiatives were affected by external factors such as policy and funding changes, with unknown impact on their effectiveness. Despite the growth of place-based initiatives to improve outcomes for disadvantaged children, the evidence for their effectiveness remains inconclusive.

The maternal health study: Study design update for a prospective cohort of first-time mothers and their firstborn children from birth to age ten.

BACKGROUND: Maternal health is critical to the health and well-being of children and families, but is rarely the primary focus of pregnancy and birth cohort studies. Globally, poor maternal health and the exposure of women and children to family violence contribute to the perpetuation and persistence of intergenerational health inequalities. OBJECTIVES: The Maternal Health Study was designed to investigate the contribution of social and obstetric risk factors to common maternal physical and psychological morbidities. Over time, our focus has expanded to include mother-child pairs and investigation of intergenerational trauma and family violence. POPULATION: A total of 1507 first-time mothers were recruited in early pregnancy from six public hospitals in Melbourne, Australia, in 2003-2005. METHODS: Women completed questionnaires or telephone interviews in early pregnancy (≤24 weeks); at 32 weeks' gestation; at three, six, nine, 12 and 18 months postpartum; and at four and ten years. At ten years, women and children were invited to participate in face-to-face interviews, which included direct assessment of children's cognitive and language development. A wide range of obstetric, social and contextual factors have been measured, including exposure to intimate partner violence (IPV) (1-year, 4-year and 10-year follow-up). RESULTS: 1507 eligible women were recruited at a mean gestation of 15 weeks. At one year, four years and ten years postpartum, 90.0%, 73.1% and 63.2% of the original cohort took part in follow-up. One in three women in the study (34.5%) reported exposure to IPV in the first ten years of motherhood: 19% in the first 12 months postpartum, 20% in the year prior to four-year follow-up and 18.3% in the year prior to ten-year follow-up. CONCLUSION: The study affords a unique opportunity to examine patterns of maternal and child health and health service use associated with exposure to IPV.

A longitudinal analysis of puberty-related cortical development.

The brain undergoes extensive structural changes during adolescence, concurrent to puberty-related physical and hormonal changes. While animal research suggests these biological processes are related to one another, our knowledge of brain development in humans is largely based on age-related processes. Thus, the current study characterized puberty-related changes in human brain structure, by combining data from two longitudinal neuroimaging cohorts. Beyond normative changes in cortical thickness, we examined whether individual differences in the rate of pubertal maturation (or "pubertal tempo") was associated with variations in cortical trajectories. Participants (N = 192; scans = 366) completed up to three waves of MRI assessments between 8.5 and 14.5 years of age, as well as questionnaire assessments of pubertal stage at each wave. Generalized additive mixture models were used to characterize trajectories of cortical development. Results revealed widespread linear puberty-related changes across much of the cortex. Many of these changes, particularly within the frontal and parietal cortices, were independent of age-related development. Males exhibiting faster pubertal tempo demonstrated greater thinning in the precuneus and frontal cortices than same-aged and -sex peers. Findings suggest that the unique influence of puberty on cortical development may be more extensive than previously identified, and also emphasize important individual differences in the coupling of these developmental processes.

Australian parents' work-family conflict: accumulated effects on children's family environment and mental health.

PURPOSE: Many parents struggle to balance their work and family responsibilities. Yet, little research in the field of social psychiatry has explored the emergence of work-family conflict (WFC) as an important social determinant of mental health, particularly for children. The current study used longitudinal Australian population-based data to investigate the impact of parents' accumulated experiences of work-family conflict on children's mental health. Levels of parent psychological distress, marital satisfaction and parenting irritability were examined as potential explanatory factors within the family environment. METHODS: The study used five waves of data from the Australian Longitudinal Study of Australian Children (LSAC), a representative community sample of Australian children and their parents. Analyses were restricted to coupled, employed mothers (1903) and fathers (1584) who reported their WFC levels in all five waves. Structural Equation Modelling (SEM) was used to examine the association between accumulated experiences of work-family conflict across all time-points (AWFC) and children's mental health at wave 5. Family environment factors were assessed as possible explanatory mediators. RESULTS: There was a significant association between AWFC and children's mental health at wave 5. Parent psychological distress, marital satisfaction and parenting irritability were all found to significantly explain this association (accounting for 66% of the total effect). CONCLUSIONS: Children whose parents have ongoing or accumulated difficulties managing their work and family responsibilities are more likely to have poorer mental health. This has important implications for family-friendly work arrangements and demonstrates the need to further understand the intergenerational impacts of parents' jobs on their children's psychological wellbeing.

The Association Between Autism Symptoms and Child Functioning in a Sample With ADHD Recruited From the Community.

Objective: Although autism spectrum disorder (ASD) symptoms are associated with poorer functioning in children with attention-deficit/hyperactivity disorder (ADHD), it is unclear which ASD symptom domains are most impairing. This study investigated whether specific ASD symptom domains were associated with child functioning in children with ADHD. Method: Parents of 164 children with ADHD completed a diagnostic interview to assess ADHD and comorbidities. Parents reported on ASD symptoms (Social Communication Questionnaire) and child quality of life (Pediatric Quality of Life Inventory 4.0). Parents and teachers completed the Strengths and Difficulties Questionnaire (emotional, conduct, and peer problems). Results: Repetitive and stereotyped behaviors were independently associated with emotional (p = .02) and conduct (p = .03) problems, and poorer quality of life (p = .004). Reciprocal social interaction deficits were independently associated with peer problems (p = .03). Conclusion: Reciprocal social interaction deficits and repetitive and stereotyped behaviors are important areas that should be focused on in ADHD assessment and treatment.
