Towards a new model of population mental health research and policy translation in the UK: Establishing a National consortium
Maternal expressions of warmth and negativity and adolescent mental health: Using longitudinal monozygotic twin‐difference analyses to approach causal inference
BACKGROUND: Emotions that mothers express about their offspring are associated with offspring mental health during childhood, but little research has explored whether this extends into adolescence. We investigated associations between maternal warmth and negativity towards twin offspring at age 10, and subsequent mental health outcomes in early and late adolescence. METHODS: The Environmental Risk (E-Risk) Longitudinal Twin Study is a population-…
Are ADHD trajectories shaped by the social environment? A longitudinal study of maternal influences on the preschool origins of delay aversion
BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is commonly attributed to neuro-cognitive deficits of genetic and/or prenatal/perinatal environmental origins. Sonuga-Barke proposed an alternative formulation, suggesting that ADHD behaviors are functional expressions of delay aversion-a strong motivational disposition to avoid or escape negative affective states evoked by delay. It is hypothesized that the strength of this disposition,…
Research Review: The impact of the Covid ‐19 pandemic on the mental health of children and young people with pre‐existing mental health and neurodevelopmental conditions – a systematic review and meta…
A framework for remotely enabled co-design with young people: Its development and application with neurodiverse children and their caregivers
We summarise key learnings and principles for fostering trust and sustaining participation with remote activities, and facilitating stakeholder design input through continuous collaboration, as well as highlight the potential benefits and challenges of utilising FREDY with neurotypical populations
Universal Credit receipt among working-age patients who are accessing specialist mental health services: Results from a novel data linkage study
BACKGROUND: In 2013, Universal Credit (UC) was introduced by the UK Government. Understanding of how UC provision is allocated among people with mental disorders, and its intersection with protected characteristics is limited. This study aimed to explore (1) how UC receipt, including UC conditionality regime, varied among users of specialist mental health services between 2013 and 2019 and (2) associations between sociodemographic and diagnostic …
To what extent do England's local offer websites adhere to the statutory guidance as set out in the special educational needs and disabilities code of practice
In England the 2014 Children and Families Act introduced wide ranging changes to the assessment of and provision for children and young people with special educational needs and disabilities (SEND). Guidance underpinning implementation was then published in the Code of Practice. Our study focuses on a key component of that legislation, known as the ‘local offer’, which requires local authorities to establish and maintain, clear, comprehensive, ac…
Association between depression diagnosis and educational attainment trajectories: An historical cohort study using linked data
BACKGROUND: Depression symptoms are thought to be associated with lower educational attainment, but patterns of change in attainment among those who receive a clinical diagnosis of depression at any point during childhood and adolescence remain unclear. METHODS: We conducted a secondary analysis of an existing data linkage between a national educational dataset (National Pupil Database) and pseudonymised electronic health records (Clinical Record…
Identifying features of risk periods for suicide attempts using document frequency and language use in electronic health records
EHR documentation frequency and language use can be used to distinguish periods distal from and proximal to a suicide attempt. However, in our study 55.0% of patients with documentation, prior to their first suicide attempt, did not have a record in the preceding 30 days, meaning that there are a high number who are not seen by services at their most vulnerable point
Changes in Physical Activity among United Kingdom University Students Following the Implementation of Coronavirus Lockdown Measures
Coronavirus disease (COVID-19) and resulting restrictions have significantly impacted physical activity levels. However, objectively measured changes in physical activity levels among UK university students during lockdown are understudied. Using data collected via remote measurement technology from a mobile physical activity tracker, this study aimed to describe the longitudinal trajectories of physical activity following the start of lockdown a…
Documenting diagnosis in child and adolescent mental healthcare: A content analysis of diagnostic statements in a psychiatric case register
Understanding clinical practice in relation to psychiatric diagnosis is important for identifying avenues for service improvement, developing clinically valid research methods and informing debate about prevailing diagnostic systems. Minimal research has explored psychiatric diagnostic practice by studying the diagnostic information present in clinical records. This study identifies, quantifies and descriptively analyses the range of contexts in …
Risk Assessment Tools and Data-Driven Approaches for Predicting and Preventing Suicidal Behavior
Risk assessment of suicidal behavior is a time-consuming but notoriously inaccurate activity for mental health services globally. In the last 50 years a large number of tools have been designed for suicide risk assessment, and tested in a wide variety of populations, but studies show that these tools suffer from low positive predictive values. More recently, advances in research fields such as machine learning and natural language processing appl…
