Background Adolescence is a critical period for social and emotional development. We sought to examine the impacts of Covid‐19 related restrictions school closures on adolescent mental health, particularly among disadvantaged, marginalised, vulnerable groups. Methods analysed four waves data – 3 pre‐Covid‐19 (2016–2019) 1 mid‐Covid‐19 (May–Aug 2020; n , 1074; 12–18 years old, >80% minority ethnic groups, 25% free meals) from REACH (Resilience, Ethnicity, AdolesCent Mental Health), an...
Accurate data linkage across large administrative databases is crucial for addressing complex research and policy questions, yet errors - stemming from inconsistent name representations can introduce biases, predominantly names not given in English. This note examines the impact of romanisation on accuracy, focusing Chinese comparing standardised systems (Jyutping Pinyin) with non-standardised Hong Kong Government Cantonese Romanisation (HKG-romanisation). We identify three primary issues:...
Importance Less than 10% of research on psychotic disorders has been conducted in settings the Global South, which refers broadly to regions Latin America, Asia, Africa, and Oceania. There is a lack basic epidemiological data distribution risks for psychoses that can inform development services many parts world. Objective To compare demographic clinical profiles cohorts cases rates untreated (proxy incidence) across within 3 economically socially diverse South. Two hypotheses were tested:...
Extensive evidence indicates that rates of psychotic disorder are elevated in more urban compared with less areas, but this largely originates from Northern Europe. It is unclear whether the same association holds globally. This study examined between residence and catchment areas India (Kancheepuram, Tamil Nadu), Nigeria (Ibadan, Oyo), Trinidad.
Abstract Background Cannabis use has been linked to psychotic disorders but this association primarily observed in the Global North. This study investigates patterns of cannabis and associations with psychoses three South (regions within Latin America, Asia, Africa Oceania) settings. Methods Case–control International Programme Research on Psychotic Disorders (INTREPID) II conducted between May 2018 September 2020. In each setting, we recruited over 200 individuals an untreated psychosis...
Careful development and evaluation of data linkage methods is limited by researcher access to personal identifiers. One solution generate synthetic identifiers, which do not pose equivalent privacy concerns, but can form a 'gold-standard' algorithm training dataset. Such could help inform choices about appropriate strategies in different settings.
Disclosures: The authors have disclosed no relevant conflicts of interest. Objectives: Culture, "the environment in which we live and work, including the beliefs, behavioral rules, traditions, rituals that bind us all together" is dynamic. A department's culture constantly evolving as initiatives are implemented to make a department great place work healthy learning environment. These include resident outings, dinners at faculty homes, workplace events, guest speakers, universal mentoring...
ObjectivesIt has been shown that record linkage methods can induce bias in resulting datasets since the quality may differ between ethno-racial groups. In this project, we used publicly available voter databases to investigate whether attributes influence similarities calculated using approximate string comparison functions on voters' names. ApproachWe 11 annual snapshots of a US database 2011 and 2021 with uniquely identifiable data. We extracted pairs same voter’s first last name values...
We aimed to develop a framework for generating synthetic identifier datasets support development and evaluation of data linkage methods. evaluated whether replicating associations between attributes identifiers improved the utility assessing error. determined steps required generate that replicate properties real-world collection. generated versions large United Kingdom cohort study (the Avon Longitudinal Study Parents Children), according quality completeness recorded over several waves...
Abstract In his winning entry for our 2024 Statistical Excellence Award Early Career Writing, Joseph Lam explores data linkage errors and biases the implication ethnically minoritised populations
Data linkage is increasingly used in health research and policy making relied on for understanding inequalities. However, linked data only as useful the underlying quality, differential rates may induce selection bias data. A mechanism that selectively compromises quality name romanisation. Converting text of a different writing system into Latin based writing, or romanisation, has long been standard process representing names character-based systems such Chinese, Vietnamese, other languages...
Objectives Apathy has been associated with frontal-subcortical pathway impairments. However, presentation of apathy and its subtypes (e.g. behavioural, cognitive, executive, social) differs amongst neurological psychiatric disorders. Our review focused on the neuroanatomy following acquired brain injury (stroke traumatic (TBI)), an aim to identify unique shared neural networks underlying in different We demonstrate a visual overview identified locations, types lesion pathways apathy. Methods...
Objectives Behavioural Initiation is defined as the innate ability to trigger action. There rich literature describing high prevalence of motivational disorders and poor behavioural initiation during rehabilitation following acquired brain injury. This not only due their neurological conditions, but also that they might have spent many weeks in wrong environment, with no stimulation other than receiving essential care. established measure for behaviour specific a setting. project aim develop...
Background/Objectives: People living with severe mental illness may be more susceptible to infection and stress, leading relapses or worsening of their health. The experiences people during the coronavirus disease 2019 (COVID-19) pandemic have seldom been captured. This study set describe experience in Tamil Nadu, India, COVID-19 pandemic. Methods: Between July December 2020, 158 age-, gender-, neighborhood-matched case − control pairs from INTREPID II completed a survey regarding...
