Prevalence of probable eating disorders and associated risk factors: An analysis of the Northern Ireland Youth Wellbeing Survey using the SCOFF.

OBJECTIVES: Eating disorders (ED) are associated with significant morbidity and mortality rates and are most common in young people aged between 15 and 19 years. Large representative surveys on disordered eating in youth are lacking. The main aims were to estimate the prevalence of disordered eating in a representative sample of 11-19 year olds in Northern Ireland and investigate the associations between probable eating disorder and a range of risk factors. DESIGNS AND METHODS: A large nationally representative household survey was conducted, and the bivariate and multivariate associations between demographic, familial, economic and psychological risk factors and probable eating disorder were assessed. RESULTS: A total of 16.2% (n = 211) of the sample met the SCOFF screening criteria for disordered eating. Probable eating disorder was associated with being female (OR = 2.44), having a parent with mental health problems (OR = 1.68), suffering from certain psychological problems, such as mood or anxiety disorder (OR = 2.55), social media disorder (OR = 2.95), being the victim of physical bullying (OR = 1.71) and having smoked (OR = 2.46). CONCLUSIONS: This study provides the first prevalence estimates of probable eating disorder among youth in Northern Ireland. Furthermore, the study identifies unique risk factors for probable eating disorder among this representative sample.

Impact of COVID-19 on mental health research: is this the breaking point?

There are many structural problems facing the UK at present, from a weakened National Health Service to deeply ingrained inequality. These challenges extend through society to clinical practice and have an impact on current mental health research, which was in a perilous state even before the coronavirus pandemic hit. In this editorial, a group of psychiatric researchers who currently sit on the Academic Faculty of the Royal College of Psychiatrists and represent the breadth of research in mental health from across the UK discuss the challenges faced in academic mental health research. They reflect on the need for additional investment in the specialty and ask whether this is a turning point for the future of mental health research.

A scoping review of international policy responses to mental health recovery during the COVID-19 pandemic.

The COVID-19 pandemic has affected people's physical and mental health. Quarantine and other lockdown measures have altered people's daily lives; levels of anxiety, depression, substance use, self-harm and suicide ideation have increased. This commentary assesses how international governments, agencies and organisations are responding to the challenge of the mental health impact of COVID-19 with the aim of informing the ongoing policy and service responses needed in the immediate and longer term. It identifies some of the key themes emerging from the literature, recognises at-risk populations and highlights opportunities for innovation within mental health services, focusing on the published academic literature, international health ministry websites and other relevant international organisations beyond the United Kingdom and Ireland. COVID-19 has challenged, and may have permanently changed, mental health services. It has highlighted and exacerbated pre-existing pressures and inequities. Many decision-makers consider this an opportunity to transform mental health care, and tackling the social determinants of mental health and engaging in prevention will be a necessary part of such transformation. Better data collection, modelling and sharing will enhance policy and service development. The crisis provides opportunities to build on positive innovations: the adaptability and flexibility of community-based care; drawing on lived experience in the design, development and monitoring of services; interagency collaboration; accelerating digital healthcare; and connecting physical and mental health.

Prevalence of self-reported mental disorders in pregnancy and associations with adverse neonatal outcomes: a population-based cross-sectional study.

BACKGROUND: Mental disorders in pregnancy are common causes of morbidity and mortality with associated risks of adverse neonatal outcomes. Our aims were to evaluate the prevalence of self-reported mental disorders in women presenting to maternity services and to determine the association between history of self-reported maternal mental disorder and adverse neonatal outcomes. METHODS: Data on all singleton pregnancies known to maternity services in Northern Ireland over the period 2010 to 2015 were extracted from the Northern Ireland Maternity System (NIMATS), including frequency data for number of pregnancies where the mother reported a history of mental disorder. Odds ratios were derived from logistic regression analyses to determine the associations between self-reported maternal mental disorder and preterm birth, low infant birth weight and APGAR scores. RESULTS: In total, 140,569 singleton pregnancies were registered using NIMATS over this period. In 18.9% of these pregnancies, the mother reported a history of at least one mental disorder. After adjustment for potential confounding factors, significant associations were demonstrated between self-reported maternal mental disorder and preterm birth (odds ratio [OR] 1.31, 95% confidence interval [CI] 1.25-1.37), low infant birth weight (OR 1.29, 95% CI 1.21-1.38) and APGAR score < 7 at 1 min (OR 1.14, 95% CI 1.10-1.19) and 5 min (OR 1.23, 95% CI 1.12 to 1.34). CONCLUSIONS: These findings emphasise the critical importance of routine enquiry regarding psychiatric history when women present to maternity services and the impact of maternal mental illnesses upon outcomes for their infants.

Prevalence rates of childhood trauma in medical students: a systematic review.

BACKGROUND: It is known that medical students suffer from high rates of mental health difficulties. In recent years there has been an increasing focus on the need to improve support and treatment services for those in difficulty. In order to meet these needs it is important to clarify the relevant aetiological factors. There is robust evidence from general population studies that a history of childhood trauma (including physical and sexual abuse and emotional neglect) predisposes to the subsequent development of mental health difficulties in adult life. It has previously been speculated that students with a history of such trauma might preferentially apply to study medicine. METHODS: This systematic review seeks to examine the existing evidence base with regard to rates of childhood trauma in medical student populations. Articles were identified through a literature search of psychINFO, web of science, Embase and medline. RESULTS: This search generated 11 articles which were deemed to meet criteria for inclusion in this review. There is a wide range of results given for rates of childhood trauma in these studies. CONCLUSIONS: The published research which examines rates of childhood trauma affecting medical students is limited and difficult to generalise from, or to use to draw firm conclusions. Given the possible negative outcomes of a history of childhood trauma in medical students, including that such a history may be associated with difficulties in a student progressing in their undergraduate and postgraduate examinations, well-organised prospective studies are required.

Reliability of reports of childhood trauma in bipolar disorder: A test-retest study over 18 months.

This study aimed to explore the reliability of self-reported trauma histories in a population with a diagnosis of bipolar disorder using the Childhood Trauma Questionnaire. Previous studies in other populations suggest high reliability of trauma histories over time, and it was postulated that a similar high reliability would be demonstrated in this population. A total of 39 patients with a confirmed diagnosis (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, criteria) were followed up and readministered the Childhood Trauma Questionnaire after 18 months. Cohen's kappa scores and intraclass correlations suggested reasonable test-retest reliability over the 18-month time period of the study for all types of childhood abuse, namely, emotional, physical, and sexual abuse and physical and emotional neglect. Intraclass correlations ranged from r = .50 (sexual abuse) to r = .96 (physical abuse). Cohen's kappas ranged from .44 (sexual abuse) to .76 (physical abuse). Retrospective reports of childhood trauma can be seen as reliable and are in keeping with results found with other mental health populations.

Prevalence and risk factors of parental mental health problems: A cross-sectional study.

An understanding of the prevalence and risk factors of parental mental health problems is important for early intervention and prevention measures and shaping services for parents and their children. However, large representative surveys of parental mental health problems and associated risk factors are lacking. The aim of this study was to estimate prevalence rates of parental mental health problems using a standardised measure of psychiatric morbidity (General Health Questionnaire; GHQ-12), in a representative sample of parents and caregivers of children and young people (2-19 years) in Northern Ireland. Further, this study explored associated risk factors of parental mental health problems. A random household survey of parents and children was conducted between June 2019 and March 2020. Parental responses on demographic, economic, familial and psychological measures were collected (N = 2815) and 22% of parents and caregivers screened positive for mental health problems. The STROBE checklist for observational research was adhered to. Multivariate logistic regression indicated that being in receipt of benefits, having poor family support, a history of adverse childhood experiences, a history of exposure to politically motivated violence (the Troubles), and a child with conduct problems and poor health were all independent risk factors of increased parental mental health problems. Findings will help to inform future commissioning and development of services and broaden understanding of the correlates of parental mental health problems.

Parental physical activity, parental mental health, children's physical activity, and children's mental health.

Introduction: The benefits of physical activity for mental health and well-being and the associations between parental mental health and children's mental health have been well established. These important issues tend to be examined separately however, and there is limited research on the associations between parent and child physical activity and mental health when all considered together. While family focused practice is recommended to provide support for parents who have mental health problems and their families and includes various components (such as psychoeducation, support for mental health and parenting), promoting physical activity for parents and children is not usually a core component of these interventions. Methods: The Northern Ireland Youth Wellbeing Survey aimed to provide estimates of the prevalence of mental health problems among children and young people. The survey also included questions about parental physical activity, parental mental health, and children's physical activity (for those aged 11-19 years). The main aim of the analysis reported in this article was to explore possible bivariate associations between parent and child physical activity and mental health and also explore these associations when all considered together. Participants were included in the analysis where there were completed interviews for the young person and one of their parents, and both young person and parent provided responses in relation to questions on weekly physical activity (n = 882). Results: The findings highlight the positive associations between parental physical activity and parental mental health, and between children's physical activity and children's mental health. They also explore some of the more complex interactions between these four variables, which suggest that gender may also be an important consideration. There were significant associations between father's physical activity and son's mental health, and son's physical activity and father's mental health. Discussions: These findings suggest that including support for parental physical activity and children's physical activity should be a routine component of family focused mental health interventions. It is important to acknowledge that there may be additional barriers to engaging in physical activity for families where a parent is experiencing mental health problems, and these should also be explored and addressed.

The influence of adverse and positive childhood experiences on young people's mental health and experiences of self-harm and suicidal ideation.

BACKGROUND: Few studies have examined the interaction of adverse childhood experiences (ACEs) and positive childhood experiences (PCEs) with mental health outcomes in nationally representative European populations. OBJECTIVE: The primary objective was to test models of resilience through investigating associations between ACEs and PCEs and young people's risk of common mood and anxiety disorders, self-harm and suicidal ideation. PARTICIPANTS AND SETTING: Data were from the Northern Ireland Youth Wellbeing Survey (NIYWS), a stratified random probability household survey conducted between June 2019 and March 2020. Analysis is based on data from adolescents aged 11-19 years (n = 1299). METHOD: Logistic regression was used to test the direct effects of ACEs and PCEs on mental health outcomes and the moderating effect of PCEs at different levels of ACE exposure. RESULTS: Prevalence rates of mental health outcomes were: common mood and anxiety disorders (16 %); self-harm (10 %); suicidal ideation (12 %). ACEs and PCEs both independently predicted common mood and anxiety disorders, self-harm and suicidal ideation. Every additional ACE increased the likelihood of a common mood and anxiety disorder (81 %), self-harm (88 %) and suicidal ideation (88 %). Every additional PCE reduced common mood and anxiety disorders (14 %), self-harm (13 %) and suicidal ideation (7 %). There was no moderating effect of PCEs on ACEs and mental health outcomes. CONCLUSION: The findings suggest that PCEs act largely independently of ACEs and that initiatives to increase PCEs can assist in the prevention of mental health problems.

The structure of the Prodromal Questionnaire-16 (PQ-16) in a non-help-seeking youth population: Exploratory and confirmatory factor analyses study.

AIMS: The present study aimed to examine the structure of the Prodromal Questionnaire-16 (PQ-16) in a non-help-seeking youth population through exploratory and confirmatory factor analysis. Previous studies have not examined the structure of this self-report measure in this age group outside a clinical setting. METHODS: Participants (n = 1165) aged 11-19 years were recruited to an epidemiological study of young people in Northern Ireland, and completed the PQ-16 alongside other measures. The dataset was split randomly in two for separate factor analyses. A polychoric correlation matrix was created and exploratory factor analysis was used to identify the optimal number of factors. In addition, based on previous studies, six models were tested through confirmatory factor analysis to determine best fit. A one-factor, 3 two-factor, a three-factor and a four-factor model were all tested. RESULTS: The exploratory factor analysis indicated a two-factor structure of the PQ-16 in this population, which we have labelled 'general unusual experiences' and 'hallucinations'. Confirmatory analysis indicated that the two-factor model identified through the exploratory analysis was the best fit for the data. DISCUSSION: The present study suggests that the structure of the PQ-16 may vary across age groups in non-clinical settings, and adds further support to the validity of the PQ-16 is a cost-effective, easy to administer self-report measure that is suitable for use in non-help-seeking populations as a screening tool for prodromal symptoms.

Healthcare staff mental health trajectories during the COVID-19 pandemic: findings from the COVID-19 Staff Wellbeing Survey.

BACKGROUND: Cross-sectional studies have shown that the COVID-19 pandemic has had a significant impact on the mental health of healthcare staff. However, it is less well understood how working over the long term in successive COVID-19 waves affects staff well-being. AIMS: To identify subpopulations within the health and social care staff workforce with differentiated trajectories of mental health symptoms during phases of the COVID-19 pandemic. METHOD: The COVID-19 Staff Wellbeing Survey assessed health and social care staff well-being within an area of the UK at four time points, separated by 3-month intervals, spanning November 2020 to August 2021. RESULTS: Growth mixture models were performed on the depression, anxiety and post-traumatic stress disorder longitudinal data. Two class solutions provided the best fit for all models. The vast majority of the workforce were best represented by the low-symptom class trajectory, where by symptoms were consistently below the clinical cut-off for moderate-to-severe symptoms. A sizable minority (13-16%) were categorised as being in the high-symptom class, a group who had symptom levels in the moderate-to-severe range throughout the peaks and troughs of the pandemic. In the depression, anxiety and post-traumatic stress disorder models, the high-symptom class perceived communication from their organisation to be less effective than the low-symptom class. CONCLUSIONS: This research identified a group of health service staff who reported persistently high mental health symptoms during the pandemic. This group of staff may well have particular needs in terms of the provision of well-being support services.

The Structure of the Prodromal Questionnaire-16 (PQ-16): Exploratory and confirmatory factor analyses in a general non-help-seeking population sample.

AIMS: To examine the structure of the Prodromal Questionnaire (PQ-16) in a non-help-seeking population through exploratory factor analysis and confirmatory factor analysis. Previous studies have not looked at the structure of this self-report measure outside clinical settings. METHODS: Participants (n = 1045) were recruited through Amazon's Mechanical Turk (MTurk), and then completed the PQ-16. The data set was split randomly in two, one being used for exploratory factor analysis (EFA) and the other for confirmatory factor analysis (CFA). A polychoric correlation matrix was created and EFA was used to explore the factor structure of the PQ-16. Four models were tested through CFA to determine best fit: one, two, three and four-factor models were all analysed. RESULTS: EFA indicated a two-factor structure in the PQ-16 in a non-help-seeking population (with a mean age = 29.7 years). Factor 1 represented perceptual abnormalities/hallucinations and factor 2 general symptoms associated with psychosis-risk. CFA indicated that all the proposed models were suitable fits for the dataset. Fit indices for the three-factor model (factor 1 representing perceptual abnormalities/hallucinations, factor 2 unusual thought content, and factor 3 negative symptom) indicated that it appeared to be a better fit for the data than the one, two, and four factor models. CONCLUSIONS: This study suggests that a three-factor model of the PQ-16 is a better fit than other proposed models in a non-help-seeking population. Future research of the structure of the PQ-16 in this population may benefit from recruiting subjects with a lower mean age than the current study.

Experiences of childhood adversity across generations - Continuity or change? A study from the Northern Ireland youth wellbeing survey.

BACKGROUND: Although a wealth of international literature consistently links cumulative experiences of adverse childhood experiences (ACEs) with physical, mental and emotional problems in later life, only a few studies have focused on intergenerational ACE exposure and research using nationally representative populations is lacking. OBJECTIVE: This paper examines intergenerational associations between parent and child ACE scores in a large nationally representative sample of parent-child dyads. PARTICIPANTS AND SETTING: Participant comprise 1042 pairs of parents and young people (11-19 year olds) who both completed questions relating to their exposure to ACEs (N = 1042) as part the Northern Ireland Youth Wellbeing Survey (NIYWS) - a stratified random probability household survey of the prevalence of mental health disorders among 2 to 19 year olds in Northern Ireland (N = 3074). METHODS: Hierarchical regression was used to identify the relationship between parent and young people ACE scores and investigate the extent to which this is influenced by child, parent, family and socio-economic variables. RESULTS: In the final model, young person ACE scores were associated with older child age (ß = 0.082, p = .016), younger parental age (ß = -0.083, p = .022), fewer children in the household (ß = -0.120, p < .001), poor child health (ß = 0.160, p < .001), low family support (ß = 0.118, p = .001) and the household being in receipt of benefits (ß = 0.223, p < .001). CONCLUSIONS: This study found a small association between parent and young person ACE exposure which was attenuated through other variables.

Prevalence and risk factors of mood and anxiety disorders in children and young people: Findings from the Northern Ireland Youth Wellbeing Survey.

OBJECTIVE: This paper presents the key findings from the Northern Ireland Youth Wellbeing Prevalence Survey (NIYWS), specifically the prevalence of common mental health disorders and their association with personal, familial and socio-economic risk factors. METHODS: The Northern Ireland Youth Wellbeing Survey (NIYWS) is a large nationally representative household survey of young people aged 2-19 years (N = 3074) and their parents (N = 2816). Data collection was by means of a stratified random probability household survey. Children and young people were eligible to take part if they were aged 2 to 19 and lived in Northern Ireland. Mood and anxiety disorders were measured using the Revised Children's Anxiety and Depression Scale (RCADS: Chorpita et al., 2000). RESULTS: Based on the cut-off scores for the RCADS 11.5% of the sample met the criteria for any mental health disorder. The most prevalent disorder was panic disorder (6.76%) and the least common was generalised anxiety disorder (2.69%). Poor child health, special educational needs, parental separation, living in a household in receipt of benefits, living in an area of deprivation and living in an urban area were all significant predictors of any mood or anxiety disorder. CONCLUSIONS: The results indicate somewhat elevated prevalence rates of mood and anxiety disorders in children and young people in Northern Ireland compared to England and other international countries. These findings can be used to help inform mental health policy and practice.

Rationale and methods of the 'Northern Ireland Youth Wellbeing Survey' and initial findings from the Strengths and Difficulties Questionnaire.

Backgrounds and Aims: The Northern Ireland Youth Wellbeing Survey (NIYWS) was commissioned by the Health and Social Care Board (NI) with the aim of providing reliable prevalence estimates of the mental health problems of children and young people aged 2-19 years. Method: The NIYWS used a random probability design, stratified by deprivation decile and county, to ensure even geographical distribution and representation. The survey used a broad range of validated measures to identify children and young people who met established clinical criteria for common mood, anxiety and behaviour disorders, trauma related disorders, as well as those at risk of autism spectrum disorder, eating disorders, future psychotic illness, self-injury or suicide. Results: Data were collected on 3074 children and young people aged 2-19 years, as well as over 2800 parents. The survey achieved a high response rate (67%) and initial findings indicated that 11% of the sample were at risk of emotional or behavioural problems. Conclusions: The NIYWS was the first large scale nationally representative survey of the mental health of children and young people in NI. Despite the legacy of political violence the initial findings show comparable levels of emotional and behavioural problems to England.

Neighbourhood effects on psychotic and depressive symptoms in the context of religious sectarianism in Northern Ireland: A data linkage study.

BACKGROUND: The incidence of psychotic disorders is higher in ethnic minorities groups. The 'ethnic density effect', in which living in a neighbourhood with a low own-group proportion increases the risk of psychosis, is one explanatory factor. The density effect in the ethno-religious and sectarian context of Northern Ireland has been found to be reversed, particularly for Catholics, in which there is harmful effect of high own-group density areas. This is partly explained by high urbanicity, deprivation and unemployment, but is otherwise not well understood. AIMS: This study aimed to examine the density effect at the level of symptomology (positive and negative psychosis symptoms and depressive symptoms) in a representative sample of people with a first episode of psychosis in Northern Ireland. METHOD: Data linkage methodology was used drawing on data from the Northern Ireland First Episode Psychosis Study (NIFEPS) and the 2001 Census of Northern Ireland. RESULTS: In total, 223 people between the ages of 18 to 64 were included in the study. A significant density effect was found for Catholics for total psychosis scores, but not for positive, negative and depressive symptoms, nor for general psychopathology, after adjusting for individual and area characteristics. The model accounted for just over 12% of the variance. No effect was found for Protestants. CONCLUSION: The findings suggest that the density effect for Catholics is unrelated to the core features of psychosis (hallucinations, delusions and anhedonia) but rather to broader cognitive and emotional disturbances and area deprivation. Explanations of exposure to social adversity and inequality are proposed, with implications for public mental health and social policy.

Feasibility and ethics of using data from the Scottish newborn blood spot archive for research.

Background: Newborn heel prick blood spots are routinely used to screen for inborn errors of metabolism and life-limiting inherited disorders. The potential value of secondary data from newborn blood spot archives merits ethical consideration and assessment of feasibility for public benefit. Early life exposures and behaviours set health trajectories in childhood and later life. The newborn blood spot is potentially well placed to create an unbiased and cost-effective population-level retrospective birth cohort study. Scotland has retained newborn blood spots for all children born since 1965, around 3 million in total. However, a moratorium on research access is currently in place, pending public consultation. Methods: We conducted a Citizens' Jury as a first step to explore whether research use of newborn blood spots was in the public interest. We also assessed the feasibility and value of extracting research data from dried blood spots for predictive medicine. Results: Jurors delivered an agreed verdict that conditional research access to the newborn blood spots was in the public interest. The Chief Medical Officer for Scotland authorised restricted lifting of the current research moratorium to allow a feasibility study. Newborn blood spots from consented Generation Scotland volunteers were retrieved and their potential for both epidemiological and biological research demonstrated. Conclusions: Through the Citizens' Jury, we have begun to identify under what conditions, if any, should researchers in Scotland be granted access to the archive. Through the feasibility study, we have demonstrated the potential value of research access for health data science and predictive medicine.

Reaching consensus on the principles of trauma-informed care in early intervention psychosis services: A Delphi study.

AIM: The current study sought to conceptualize and reach consensus on the principles of trauma-informed care in early intervention psychosis services. METHODS: A three-phase Delphi method was employed in this study. Experts included researchers, service providers and Experts by Experience in the area of early intervention in psychosis. In the initial qualitative phase, an expert panel (n = 57) shared their views on the constituents of trauma-informed care in early intervention psychosis services. Thematic analysis led to the generation of statement items. The expert panel was asked to rate the extent to which each statement item was an essential principle of trauma-informed care, leading to consensus of endorsed principles. RESULTS: Qualitative analysis of the first phase data led to the identification of 185 distinct statements which were compiled into an online questionnaire for the panel to rate in Phase 2. The Phase 2 questionnaire was completed by 42 experts, with the endorsement of seven principles. In Phase 3, the panel were invited to re-rate 24 statements. This phase was completed by 39 panel members, with the acceptance of a further nine principles. Consensus was achieved resulting in the endorsement of 16 essential principles of trauma-informed care. CONCLUSIONS: The study offers novel understanding of the conceptualisation of trauma-informed care in early intervention services and suggests principles which are widely agreed by experts in the field. The recommendations may inform the adoption of consistently delivered trauma-informed care in early interventions in psychosis and facilitate the evaluation and development of services.

The association between sleep quality and attenuated psychotic symptoms.

AIM: To determine if poor sleep makes a unique contribution in predicting the likelihood of experiencing six or more attenuated psychotic symptoms and associated distress, after examining and controlling for sociodemographic factors, depression and drug/alcohol use. METHOD: An online survey was conducted using Amazon's online crowdsourcing service Mechanical Turk (MTurk). The sample was 1013 adults (18 to 36 years) from the general population in the United States. The survey consisted of the Prodromal Questionnaire 16 (PQ-16), the Pittsburgh Sleep Quality Index, the Patient Health Questionnaire 9, the Drug Abuse Screening Test 10 and the Alcohol Use Disorders Identification Test. Regression analyses were performed with the PQ-16 as the dependent variable, and sleep quality as the predictor variable, holding constant sociodemographic variables, depression, and alcohol/drug abuse. RESULTS: 37% of the sample endorsed six or more PQ-16 items, which may be suggestive of an at-risk mental state, with sleep disturbance significantly increasing the likelihood (Odds ratio 2.09 < .001) of endorsing six or more PQ-16 items. After controlling for sociodemographic variables, depression and drug/alcohol abuse, poor sleep quality made a unique contribution of 5.8% of the variance accounted for in level of distress experienced by attenuated psychotic symptoms. CONCLUSION: Effective treatment of sleep disturbance may reduce the likelihood ofexperiencing attenuated psychotic symptoms and associated distress.

COVID-19 Staff Wellbeing Survey: longitudinal survey of psychological well-being among health and social care staff in Northern Ireland during the COVID-19 pandemic.

BACKGROUND: Throughout the coronavirus disease 2019 (COVID-19) pandemic, health and social care workers have faced unprecedented professional demands, all of which are likely to have placed considerable strain on their psychological well-being. AIMS: To measure the national prevalence of mental health symptoms within healthcare staff, and identify individual and organisational predictors of well-being. METHOD: The COVID-19 Staff Wellbeing Survey is a longitudinal online survey of psychological well-being among health and social care staff in Northern Ireland. The survey included four time points separated by 3-month intervals; time 1 (November 2020; n = 3834) and time 2 (February 2021; n = 2898) results are presented here. At time 2, 84% of respondents had received at least one dose of a COVID-19 vaccine. The survey included four validated psychological well-being questionnaires (depression, anxiety, post-traumatic stress and insomnia), as well as demographic and organisational measures. RESULTS: At time 1 and 2, a high proportion of staff reported moderate-to-severe symptoms of depression (30-36%), anxiety (26-27%), post-traumatic stress (30-32%) and insomnia (27-28%); overall, significance tests and effect size data suggested psychological well-being was generally stable between November 2020 and February 2021 for health and social care staff. Multiple linear regression models indicated that perceptions of less effective communication within their organisation predicted greater levels of anxiety, depression, post-traumatic stress and insomnia. CONCLUSIONS: This study highlights the need to offer psychological support to all health and social care staff, and to communicate with staff regularly, frequently and clearly regarding COVID-19 to help protect staff psychological well-being.
