Patterns of health service use for children with mental disorders in an Australian state population cohort.

Objectives: The rate of mental health services provided to children and young people is increasing worldwide, including in Australia. The aim of this study was to describe patterns of hospital and ambulatory mental health service use among a large population cohort of adolescents followed from birth, with consideration of variation by age, sex and diagnosis.

Methods: Characteristics of services provided for children with mental disorder diagnoses between birth and age 17.

Levels of Involvement with Child Protection Services Associated with Early Adolescent Police Contact as a Victim and Person of Interest.

The relationship between childhood maltreatment and subsequent offending/victimization is well established. However, the magnitude of this relationship for different levels of child protection services (CPS) involvement is poorly understood, due to measurement issues, lack of longitudinal data, and reliance on reports of substantiated maltreatment, which can underestimate the impact of maltreatment. This study examined associations between CPS involvement during childhood (ages 0 to <11 years) and police services contact (as a victim and/or a person of interest) for criminal incidents in early adolescence (11 to ~14 years), differentiated according to levels of CPS involvement (i.

Childhood Schizotypy and Adolescent Mental Disorder.

Background And Hypothesis: Schizotypy provides a framework for understanding the developmental nature of psychotic disorders and a means of identifying "at-risk" individuals early in the lifespan. However, there is a lack of prospective longitudinal research examining the relationship between schizotypy in childhood and later psychotic and other mental disorders. We hypothesized that distinct profiles of schizotypy in childhood would be differentially associated with psychotic and other mental disorders emerging later in adolescence.

Early life exposure to air pollution and psychotic-like experiences, emotional symptoms, and conduct problems in middle childhood.

Background: Air pollution has been linked to a variety of childhood mental health problems, but results are inconsistent across studies and the effect of exposure timing is unclear. We examined the associations between air pollution exposure at two time-points in early development and psychotic-like experiences (PLEs), and emotional and conduct symptoms, assessed in middle childhood (mean age 11.5 years).

Global Prevalence of Childhood Exposure to Physical Violence within Domestic and Family Relationships in the General Population: A Systematic Review and Proportional Meta-Analysis.

Efforts to identify and prevent childhood exposure to physical violence within domestic and family relationships must be underpinned by reliable prevalence estimates to ensure the appropriate allocation of resources and benchmarks for assessing intervention efficacy. We conducted a systematic review and meta-analysis of the global prevalence of childhood exposure to physical domestic and family violence separately as a victim or witness. Searches were conducted in , , and Studies were included if they were peer-reviewed, published in English, had a representative sample, unweighted estimates, and were published between January 2010 and December 2022.

Conditions of Birth and Early Childhood Developmental Risk for Mental Disorders.

Distinct classes of children in the general population are at increased odds of later mental illness and other adverse outcomes according to patterns of early childhood developmental vulnerability. If certain risk factors known at the time of birth are reliably associated with membership in early childhood risk classes, then preventative interventions could be initiated in the earliest years of life. Associations between 14 factors known at the time of birth and membership in early childhood risk classes were examined in 66,464 children.

Psychiatric illness and the risk of reoffending: recurrent event analysis for an Australian birth cohort.

Background: Psychiatric illness is a well-established risk factor for criminal justice system involvement, but less is known about the relationships between specific psychiatric illnesses and reoffending. Research typically examines reoffending as a single discrete event. We examined the relationship between different psychiatric disorders and types of reoffending while accounting for multiple reoffending events over time.

Parental mental disorders and offspring schizotypy in middle childhood: an intergenerational record linkage study.

Purpose: To investigate relationships between distinct schizotypy risk profiles in childhood and the full spectrum of parental mental disorders.

Methods: Participants were 22,137 children drawn from the New South Wales Child Development Study, for whom profiles of risk for schizophrenia-spectrum disorders in middle childhood (age ~ 11 years) were derived in a previous study. A series of multinomial logistic regression analyses examined the likelihood of child membership in one of three schizotypy profiles (true schizotypy, introverted schizotypy, and affective schizotypy) relative to the children showing no risk, according to maternal and paternal diagnoses of seven types of mental disorders.

Item response theory analysis of self-reported social-emotional learning competencies in an Australian population cohort aged 11 years.

Childhood social and emotional competencies are recognized as teachable skills affecting well-being and developmental outcomes across the life span. This study sought to develop and validate a brief self-report measure of social-emotional competencies in middle childhood. The study used items from the administered to a representative subsample of the cohort, comprising sixth grade students ( = 26,837; aged 11-12 years) attending primary school in New South Wales, Australia.

Out-of-home care characteristics associated with childhood educational underachievement, mental disorder, and police contacts in an Australian population sample.

Background: Children in out-of-home care (OOHC) are generally at increased risk of health and social adversities compared to their peers. However, the experiences of children in OOHC are not uniform and their associated health and social indices may vary in relation to characteristics of OOHC placements and child protection contact.

Objective: To examine associations between a range of characteristics of OOHC placements and child protection contact (e.

Relationships between parental mental illness and/or offending and offspring contact with the police in childhood: Findings from a longitudinal record-linkage study.

Background: Parental offending and mental illness are associated with an increased risk of criminal behaviour in offspring during adolescence and adulthood, but the impact of such problems on younger children, including children's experiences of victimisation, is less well known.

Aim: To investigate the associations between parental offending and mental illness recorded prior to their offspring's age of 5 years and their offspring's contact with police as a 'person of interest', 'victim' or 'witness' between ages 5 and 13 years.

Methods: Our sample consisted of 72,771 children and their parents drawn from the New South Wales Child Development Study, an Australian longitudinal population-based record linkage study.

Pathways from developmental vulnerabilities in early childhood to schizotypy in middle childhood.

Objectives: Childhood disturbances in social, emotional, language, motor and cognitive functioning, and schizotypy have each been implicated as precursors of schizophrenia-spectrum disorders. We investigated whether relationships between early childhood developmental vulnerabilities and childhood schizotypy are mediated by educational underachievement in middle childhood.

Methods: Participants were members of a large Australian (n = 19,216) population cohort followed longitudinally.

Intergenerational (Dis)continuity of Child Maltreatment: Variation by Parents' Childhood Victimization Experiences and Sex.

This longitudinal population-based study examines the association between maltreatment victimization experiences and the likelihood of intergenerational (dis)continuity of maltreatment. Our data include all individuals born in 1983/1984 in Queensland (QLD), Australia who are registered as parents via birth records and who experienced system contacts for maltreatment victimization in childhood ( = 2906). Child safety data on system contacts as a child victim and person responsible for harm to a child were obtained from the Department of Children, Youth Justice and Multicultural Affairs.

Cumulative Environmental Risk in Early Life: Associations With Schizotypy in Childhood.

Background And Hypothesis: Psychotic disorders are associated with a growing number of recognized environmental exposures. Cumulative exposure to multiple environmental risk factors in childhood may contribute to the development of different patterns of schizotypy evident in early life. Hypotheses were that distinct profiles of schizotypy would have differential associations with a cumulative score of environmental risk factors.

Early developmental vulnerabilities following exposure to domestic violence and abuse: Findings from an Australian population cohort record linkage study.

Early life exposure to Domestic Violence and Abuse (DVA) is associated with poor psychosocial and cognitive development in childhood. However, most prior research uses mother-reported involvement in DVA as a proxy indicator of child exposure; studies using direct measures of child exposure to DVA are scarce, especially among representative population-based samples. We address this gap by using longitudinal, population-based data from an Australian record linkage study of children to examine the associations between early life exposure to DVA and early childhood developmental vulnerability.

Regional mapping of early childhood risk for mental disorders in an Australian population sample.

Aim: Population-level profiles of risk for later childhood mental disorders have been identified in patterns of early developmental vulnerabilities using Australian Early Developmental Census. We sought to demonstrate the geographical distribution of these early childhood risk profiles for mental illness, to inform policy decisions for place-sensitive provision of health and allied services.

Methods: Using geographic information system techniques, we mapped the regional percentage of children at highest risk for mental disorders across the state of New South Wales (NSW), according to Local Government Areas, for 82 891 children in the NSW Child Development Study.

Developmental profiles of schizotypy in the general population: A record linkage study of Australian children aged 11-12 years.

Objectives: The detection of young people at high risk for psychotic disorders has been somewhat narrowly focused on overt symptom-based markers that reflect mild reality distortion (e.g., psychotic-like experiences), or prodromal syndromes that are proximal to psychosis onset.

Profiles of Resilience from Early to Middle Childhood among Children Known to Child Protection Services.

Objective: The processes facilitating resilience are likely to be influenced by individual, familial and contextual factors that are dynamic across the life-course. These factors have been less studied in relation to resilience profiles evident in the developmental period between early to middle childhood, relative to later periods of adolescence or adulthood.

Method: This study examined factors associated with in a cohort of 4,716 children known to child protection services by age 13 years, in the Australian State of New South Wales.

Self-reported mental health of children known to child protection services: an Australian population-based record linkage study.

Maltreated children are vulnerable to adverse mental health outcomes. Information about how children's mental health needs vary according to different levels of child protection contact (potentially culminating in out-of-home care [OOHC]) is valuable for the effective provision of services. This study aimed to examine associations between different levels of contact with child protection services before the age of 10 years and self-reported mental health difficulties at age 11 years.

Incidence of Early Police Contact Among Children With Emerging Mental Health Problems in Australia.

Importance: In adulthood and adolescence, mental health vulnerability is known to be associated with risk of criminal justice system contact as both a perpetrator and survivor of crime, but whether this association is apparent early in child development is unknown. Prevention of poor outcomes, including repeated contact with the criminal justice system, relies on the identification of vulnerability early in life and at the start of such contact.

Objective: To ascertain whether children with emotional or behavioral problems and general developmental vulnerabilities are at an increased risk of subsequent contact with police as a person of interest, a survivor of crime, or a witness.

"Who maltreats? Distinct pathways of intergenerational (dis)continuity of child maltreatment".

Background: Maltreatment victimization history is an established risk factor for child maltreatment across generations. However, many parents with a victimization history do not maltreat, and many parents with no victimization history do have victimized children.

Objectives: To understand differences in demographic and maltreatment risk factors across the following intergenerational patterns of maltreatment: cycle maintainers, cycle breakers, cycle initiators, and a comparison group (no maltreatment).

Prevalence of psychiatric disorders for Indigenous Australians: a population-based birth cohort study.

Aims: Limited information exists about the prevalence of psychiatric illness for Indigenous Australians. This study examines the prevalence of diagnosed psychiatric disorders in Indigenous Australians and compares this to non-Indigenous Australians. The aims were to: (1) determine prevalence rates for psychiatric diagnoses for Indigenous Australians admitted to hospital; and (2) examine whether the profile of psychiatric diagnoses for Indigenous Australians was different compared with non-Indigenous Australians.

Transitions between socio-emotional and cognitive vulnerability profiles from early to middle childhood: a population study using multi-agency administrative records.

Adult psychosocial difficulties, including psychiatric disorders, are often preceded by childhood psychosocial vulnerabilities, presenting critical windows of opportunity for preventative intervention. The present study aimed to identify longitudinal patterns (representing transitions between profiles) of childhood socio-emotional and cognitive vulnerability in the general population from early to middle childhood, in relation to key risk factors (e.g.
