The Longitudinal Impact of Social Media Use on UK Adolescents' Mental Health: Longitudinal Observational Study
BACKGROUND: Cross-sectional studies have found a relationship between social media use and depression and anxiety in young people. However, few longitudinal studies using representative data and mediation analysis have been conducted to understand the causal pathways of this relationship. OBJECTIVE: This study aims to examine the longitudinal relationship between social media use and young people's mental health and the role of self-esteem and social connectedness as potential mediators. METHODS: The sample included 3228 participants who were 10- to 15-year-olds from Understanding Society (2009-2019), a UK longitudinal household survey. The number of hours spent on social media was measured on a 5-point scale from "none" to "7 or more hours" at the ages of 12-13 years. Self-esteem and social connectedness (number of friends and happiness with friendships) were measured at the ages of 13-14 years. Mental health problems measured by the Strengths and Difficulties Questionnaire were assessed at the ages of 14-15 years. Covariates included demographic and household variables. Unadjusted and adjusted multilevel linear regression models were used to estimate the association between social media use and mental health. We used path analysis with structural equation modeling to investigate the mediation pathways. RESULTS: In adjusted analysis, there was a nonsignificant linear trend showing that more time spent on social media was related to poorer mental health 2 years later (n=2603, β=.21, 95% CI 0.43 to 0.84; P=.52). In an unadjusted path analysis, 68% of the effect of social media use on mental health was mediated by self-esteem (indirect effect, n=2569, β=.70, 95% CI 0.15-1.30; P=.02). This effect was attenuated in the adjusted analysis, and it was found that self-esteem was no longer a significant mediator (indirect effect, n=2316, β=.24, 95% CI 0.12 to 0.66; P=.22). We did not find evidence that the association between social media and mental health was mediated by social connectedness. Similar results were found in imputed data. CONCLUSIONS: There was little evidence to suggest that more time spent on social media was associated with later mental health problems in UK adolescents. This study shows the importance of longitudinal studies to examine this relationship and suggests that prevention strategies and interventions to improve mental health associated with social media use could consider the role of factors like self-esteem
The longitudinal effect of social media use on adolescent mental health in the UK: findings from the UK Longitudinal Household Study
BACKGROUND: Cross-sectional studies have suggested an association between the use of social media and depression and anxiety in young people. We examined the longitudinal relationship between social media use and young people's mental health, and the role of self-esteem and social connectedness as potential mediators. METHODS: Adolescents (aged 10-15 years) from the UK Longitudinal Household Study (2009-19) were included. Mental health was measured by the Strengths and Difficulties Questionnaire Total Difficulties score. The number of hours spent on social media was measured on a 5-point scale, from zero to âĽ7 h. Self-esteem and social connectedness were measured at ages 13-14 years. Covariates included demographic and household variables. Unadjusted and adjusted multilevel linear regression models explored whether social media use at ages 12-13 years predicted mental health at ages 14-15 years (expressed as beta values and 95% CIs). Path analysis with structural equation modelling was used to investigate the mediation pathways. FINDINGS: We included 3228 adolescents (1659 [51¡4%] girls and 1569 [48¡6%] boys) for whom social media and mental health data at ages 12-13 years and 14-15 years were available. In adjusted analysis, no association between time spent on social media and poorer mental health was identified (n=2603; b=0¡21 [95% CI -0¡43 to 0¡84]; p=0¡52). In adjusted path analysis, there was no mediation of self-esteem (indirect effect; n=2316; b=0¡24 [95% CI -0¡12 to 0¡66]; p=0¡22) or social connectedness (indirect effect; -0¡03 [-0¡20 to 0¡12]; p=0¡74), but in unadjusted analysis, 68% of the effect of social media use on mental health was mediated by self-esteem (indirect effect; n=2569; 0¡70 [0¡15 to 1¡30]; p=0.016) but not by social connectedness. Similar results were found when the analysis was re-run on a multiply imputed dataset that filled in missing values using multiple imputation. INTERPRETATION: Our data show the importance of longitudinal evidence. We found there was little evidence to suggest a causal relationship between the use of social media and mental health issues 2 years later. Interventions that address social media use alone might not improve young people's mental health, and considering factors such as self-esteem might be more effective.

Workplace Interventions to Reduce Occupational Stress for Older Workers: A Systematic Review
The working life of individuals is now longer because of increases to state pension age in the United Kingdom. Older workers may be at particular risk in the workplace, compared with younger workers. Successful workplace interventions to reduce occupational stress amongst older workers are essential, but little is known about their effectiveness. The aim is to evaluate current evidence of the effectiveness of interventions for reducing stress in older workers in non-healthcare settings. Four database searches were conducted. The search terms included synonyms of âinterventionâ, âworkplaceâ and âoccupational stressâ to identify original studies published since 2011. Dual screening was conducted on the sample to identify studies which met the inclusion criteria. The RoB 2.0 tool for RCTs was used to assess the risk of bias. From 3708 papers retrieved, ten eligible papers were identified. Seven of the papersâ interventions were deemed effective in reducing workplace stress. The sample size for most studies was small, and the effectiveness of interventions were more likely to be reported when studies used self-report measures, rather than biological measures. This review indicates that workplace interventions might be effective for reducing stress in older workers. However, there remains an absence of high-quality evidence in this field
The use of experimental vignette studies to identify drivers of variations in the delivery of health care: a scoping review
Abstract: Background: Identifying how unwarranted variations in healthcare delivery arise is challenging. Experimental vignette studies can help, by isolating and manipulating potential drivers of differences in care. There is a lack of methodological and practical guidance on how to design and conduct these studies robustly. The aim of this study was to locate, methodologically assess, and synthesise the contribution of experimental vignette studies to the identification of drivers of unwarranted variations in healthcare delivery. Methods: We used a scoping review approach. We searched MEDLINE, Embase, Web of Science and CINAHL databases (2007â2019) using terms relating to vignettes and variations in healthcare. We screened title/abstracts and full text to identify studies using experimental vignettes to examine drivers of variations in healthcare delivery. Included papers were assessed against a methodological framework synthesised from vignette study design recommendations within and beyond healthcare. Results: We located 21 eligible studies. Study participants were almost exclusively clinicians (18/21). Vignettes were delivered via text (n = 6), pictures (n = 6), video (n = 6) or interactively, using face-to-face, telephone or online simulated consultations (n = 3). Few studies evaluated the credibility of vignettes, and many had flaws in their wider study design. Ten were of good methodological quality. Studies contributed to understanding variations in care, most commonly by testing hypotheses that could not be examined directly using real patients. Conclusions: Experimental vignette studies can be an important methodological tool for identifying how unwarranted variations in care can arise. Flaws in study design or conduct can limit their credibility or produce biased results. Their full potential has yet to be realised
The implementation of chlamydia screening: a cross-sectional study in the south east of England
Background England's National Chlamydia Screening Programme (NCSP) provides opportunistic testing for under 25 year-olds in healthcare and non-healthcare settings. The authors aimed to explore relationships between coverage and positivity in relation to demographic characteristics or setting, in order to inform efficient and sustainable implementation of the NCSP.
Methods The authors analysed mapped NCSP testing data from the South East region of England between April 2006 and March 2007 inclusive to population characteristics. Coverage was estimated by sex, demographic characteristics and service characteristics, and variation in positivity by setting and population group.
Results Coverage in females was lower in the least deprived areas compared with the most deprived areas (OR 0.48; 95% CI 0.45 to 0.50). Testing rates were lower in 20 1324-year-olds compared with 15 1319-year-olds (OR 0.69; 95% CI 0.67 to 0.72 for females and OR 0.67; 95% CI 0.64 to 0.71 for males), but positivity was higher in older males.
Females were tested most often in healthcare services, which also identified the most positives. The greatest proportions of male tests were in university (27%) and military (19%) settings which only identified a total of 11% and 13% of total male positives respectively. More chlamydia-positive males were identified through healthcare services despite fewer numbers of tests.
Conclusions Testing of males focused on institutional settings where there is a low yield of positives, and limited capacity for expansion. By contrast, the testing of females, especially in urban environments, was mainly through established healthcare services. Future strategies should prioritise increasing male testing in healthcare settings
The effectiveness of using virtual patient educational tools to improve medical studentsâ clinical reasoning skills: a systematic review
Background: Use of virtual patient educational tools could fll the current gap in the teaching of clinical reasoning
skills. However, there is a limited understanding of their efectiveness. The aim of this study was to synthesise the
evidence to understand the efectiveness of virtual patient tools aimed at improving undergraduate medical studentsâ
clinical reasoning skills.
Methods: We searched MEDLINE, EMBASE, CINAHL, ERIC, Scopus, Web of Science and PsycINFO from 1990 to January 2022, to identify all experimental articles testing the efectiveness of virtual patient educational tools on medical
studentsâ clinical reasoning skills. Quality of the articles was assessed using an adapted form of the MERSQI and the
NewcastleâOttawa Scale. A narrative synthesis summarised intervention features, how virtual patient tools were
evaluated and reported efectiveness.
Results: The search revealed 8,186 articles, with 19 articles meeting the inclusion criteria. Average study quality was
moderate (M=6.5, SD=2.7), with nearly half not reporting any measurement of validity or reliability for their clinical
reasoning outcome measure (8/19, 42%). Eleven articles found a positive efect of virtual patient tools on reasoning (11/19, 58%). Four reported no signifcant efect and four reported mixed efects (4/19, 21%). Several domains of
clinical reasoning were evaluated. Data gathering, ideas about diagnosis and patient management were more often
found to improve after virtual patient use (34/47 analyses, 72%) than application of knowledge, fexibility in thinking
and problem-solving (3/7 analyses, 43%).
Conclusions: Using virtual patient tools could efectively complement current teaching especially if opportunities
for face-to-face teaching or other methods are limited, as there was some evidence that virtual patient educational
tools can improve undergraduate medical studentsâ clinical reasoning skills. Evaluations that measured more case
specifc clinical reasoning domains, such as data gathering, showed more consistent improvement than general
measures like problem-solving. Case specifc measures might be more sensitive to change given the context dependent nature of clinical reasoning. Consistent use of validated clinical reasoning measures is needed to enable a metaanalysis to estimate efectiveness
Asynchronous digital health interventions for reviewing asthma: a mixed-methods systematic review protocol
INTRODUCTION: People living with asthma require regular reviews to address their concerns and questions, assess control, review medication, and support self-management. However, practical barriers to attending face-to-face consultations might limit routine reviews. Reviewing asthma using asynchronous digital health interventions could be convenient for patients and an efficient way of maintaining communication between patients and healthcare professionals and improving health outcomes. We, therefore, aim to conduct a mixed-methods systematic review to assess the effectiveness of reviewing asthma by asynchronous digital health interventions and explore the views of patients and healthcare professionals about the role of such interventions in delivering asthma care. METHODS: We will search MEDLINE, Embase, Scopus, PsycInfo, CINAHL, and Cochrane Library from 2001 to present without imposing any language restrictions. We are interested in studies of asynchronous digital health interventions used either as a single intervention or contributing to mixed modes of review. Two review authors will independently screen titles and abstracts, and retrieve potentially relevant studies for full assessment against the eligibility criteria and extract data. Disagreements will be resolved by discussion with the review team. We will use 'Downs and Black' checklist, 'Critical Appraisal Skills Programme', and 'Mixed Methods Appraisal Tool' to assess methodological quality of quantitative, qualitative, and mixed-methods studies respectively. After synthesising quantitative (narrative synthesis) and qualitative (thematic synthesis) data separately, we will integrate them following methods outlined in the Cochrane Handbook for Systematic Reviews of Interventions. CONCLUSION: The findings of this review will provide insights into the role of asynchronous digital health interventions in the routine care of people living with asthma.

Are some areas more equal than others? : Socioeconomic inequality in potentially avoidable emergency hospital admissions within English local authority areas
Objectives Reducing health inequalities is an explicit goal of England's health system. Our aim was to compare the performance of English local administrative areas in reducing socioeconomic inequality in emergency hospital admissions for ambulatory care sensitive chronic conditions. Methods We used local authority area as a stable proxy for health and long-term care administrative geography between 2004/5 and 2011/12. We linked inpatient hospital activity, deprivation, primary care, and population data to small area neighbourhoods (typical population 1500) within administrative areas (typical population 250,000). We measured absolute inequality gradients nationally and within each administrative area using neighbourhood-level linear models of the relationship between national deprivation and age-sex-adjusted emergency admission rates. We assessed local equity performance by comparing local inequality against national inequality to identify areas significantly more or less equal than expected; evaluated stability over time; and identified where equity performance was steadily improving or worsening. We then examined associations between change in socioeconomic inequalities and change in within-area deprivation (gentrification). Finally, we used administrative area-level random and fixed effects models to examine the contribution of primary care to inequalities in admissions. Results Data on 316 administrative areas were included in the analysis. Local inequalities were fairly stable between consecutive years, but 32 areas (10%) showed steadily improving or worsening equity. In the 21 improving areas, the gap between most and least deprived fell by 3.9 admissions per 1000 (six times the fall nationally) between 2004/5 and 2011/12, while in the 11 areas worsening, the gap widened by 2.4. There was no indication that measured improvements in local equity were an artefact of gentrification or that changes in primary care supply or quality contributed to changes in inequality. Conclusions Local equity performance in reducing inequality in emergency admissions varies both geographically and over time. Identifying this variation could provide insights into which local delivery strategies are most effective in reducing such inequalities
The value of theory in programmes to implement clinical guidelines: Insights from a retrospective mixed-methods evaluation of a programme to increase adherence to national guidelines for chronic disease in primary care.
BACKGROUND: Programmes have had limited success in improving guideline adherence for chronic disease. Use of theory is recommended but is often absent in programmes conducted in 'real-world' rather than research settings. MATERIALS AND METHODS: This mixed-methods study tested a retrospective theory-based approach to evaluate a 'real-world' programme in primary care to improve adherence to national guidelines for chronic obstructive pulmonary disease (COPD). Qualitative data, comprising analysis of documents generated throughout the programme (n>300), in-depth interviews with planners (clinicians, managers and improvement experts involved in devising, planning, and implementing the programme, n = 14) and providers (practice clinicians, n = 14) were used to construct programme theories, experiences of implementation and contextual factors influencing care. Quantitative analyses comprised controlled before-and-after analyses to test 'early' and evolved' programme theories with comparators grounded in each theory. 'Early' theory predicted the programme would reduce emergency hospital admissions (EHA). It was tested using national analysis of standardized borough-level EHA rates between programme and comparator boroughs. 'Evolved' theory predicted practices with higher programme participation would increase guideline adherence and reduce EHA and costs. It was tested using a difference-in-differences analysis with linked primary and secondary care data to compare changes in diagnosis, management, EHA and costs, over time and by programme participation. RESULTS: Contrary to programme planners' predictions in 'early' and 'evolved' programme theories, admissions did not change following the programme. However, consistent with 'evolved' theory, higher guideline adoption occurred in practices with greater programme participation. CONCLUSIONS: Retrospectively constructing theories based on the ideas of programme planners can enable evaluators to address some limitations encountered when evaluating programmes without a theoretical base. Prospectively articulating theory aided by existing models and mid-range implementation theories may strengthen guideline adoption efforts by prompting planners to scrutinise implementation methods. Benefits of deriving programme theory, with or without the aid of mid-range implementation theories, however, may be limited when the evidence underpinning guidelines is flawed
A Protocol for a Mixed-Methods Process Evaluation of a Local Population Health Management System to Reduce Inequities in COVID-19 Vaccination Uptake
Population health management is an emerging technique to link and analyse patient data across several organisations in order to identify population needs and plan care. It is increasingly used in England and has become more important as health policy has sought to drive greater integration across health and care organisations. This protocol describes a mixed-methods process evaluation of an innovative population health management system in North Central London, England, serving a population of 1.5 million. It focuses on how staff have used a specific tool within North Central Londonâs population health management system designed to reduce inequities in COVID-19 vaccination. The COVID-19 vaccination Dashboard was first deployed from December 2020 and enables staff in North London to view variations in the uptake of COVID-19 vaccinations by population characteristics in near real-time. The evaluation will combine interviews with clinical and non-clinical staff with staff usage analytics, including the volume and frequency of staff Dashboard views, to describe the toolâs reach and identify possible mechanisms of impact. While seeking to provide timely insights to optimise the design of population health management tools in North Central London, it also seeks to provide longer term transferable learning on methods to evaluate population health management systems
