Challenges and validation in estimating teacher value-added in English secondary schools
Researchers in the United States have frequently used non-experimental data, including annual student test scores, to estimate teacher value-added (TVA). Experimental studies have largely validated this approach within the US context. Similar data are increasingly available in England. However, differences in the school systems, the way in which students are allocated to schools and teachers, and assessment practices present distinctive challenge…
Assessing the impact of hybrid school visits in initial teacher education: A mixed-methods randomised controlled trial and process evaluation
Initial estimates of teacher value‐added in English primary schools
A sizeable literature investigating teacher test score value‐added—the extent to which pupils make different rates of progress under different teachers—has emerged in the United States. While there is much interest in estimating teacher value‐added in other countries such as England, progress has been limited by the lack of datasets linking teachers and pupils. We overcome this issue by drawing on internal assessment data from primary schools acr…
Differences in need for and access to eye health services between older people with and without disability: A cross-sectional survey in four districts of northern Uganda
Eye health and disability are both common among older people, and it is important to understand how disability relates to visual health status and access to services. While people with disabilities face barriers to accessing health services, few studies have measured participants’ functional status in domains other than vision and little evidence exists on how disability impacts eye health services access. This paper describes how visual impairme…
Women with disabilities’ use of maternal care services in sub-Saharan Africa
This study is the first quantitative, multi-country study in sub-Saharan Africa to examine maternal care seeking patterns, demonstrating important data on maternal health indicators for women with disabilities
Inequities in birth registration, violent discipline, and child labour by disability status and sex: Evidence from the Multiple Indicator Cluster Surveys in 24 countries
Nearly 240 million children are estimated to have a disability globally. We describe inequities by disability status and sex in birth registration, child labour, and violent discipline outcomes. Data come from Round 6 of the Multiple Indicator Cluster Survey programme and includes 323,436 children, aged 2–17 years in 24 countries. We estimated non-registration of birth, child labour, and violent discipline, stratified by sex and disability in eac…
Cognition in older adults in Uganda: Correlates, trends over time and association with mortality in prospective population study
Dementia is an important and growing issue in sub-Saharan Africa, but epidemiological data are lacking. Risk factors may differ from other regions due to high stroke incidence and HIV prevalence. Understanding the epidemiology of cognition in older adults in Africa is crucial for informing public health strategies to improve the lives of people with dementia and their carers. The Wellbeing of Older People Study in Uganda is an open cohort of adul…
The Impact of the Disability Allowance on Financial Well-Being in the Maldives: Quasi-experimental Study
There are few impact evaluations of social assistance programmes amongst people with disabilities, despite the increasing popularity of disability-targeted programmes. The Disability Allowance in the Maldives is a non-contributory, non-means-tested and unconditional cash transfer of MVR 2000 (US$130) per month. This study explores the impact of the Disability Allowance on financial well-being using a quasi-experimental study design with differenc…
Will it work here? A realist approach to local decisions about implementing interventions evaluated as effective elsewhere
There is increasing interest in what evidence is needed to inform decisions about transporting interventions evaluated as effective to new settings. There has been less attention to how local decision-makers decide whether to implement such interventions immediately or subject to further evaluation. Using the example of school-based social and emotional learning, we consider this drawing on realist methods. We suggest decisions need to assess exi…
Disability-inclusive Covid-19 response: What it is, why it is important and what we can learn from the United Kingdom’s response
All too often, disabled people are left behind in emergencies, and this is a risk in the ongoing COVID-19 pandemic. This is an important issue, as globally there are approximately one billion people with disabilities. This number includes one in three people aged over 60, who are the group at greatest risk from COVID-19. The COVID-19 pandemic in the UK has highlighted additional difficulties that disabled people may face. Complying with preventat…
Disability-inclusive responses to Covid-19: Lessons learnt from research on social protection in low- and middle-income countries
The Samata intervention to increase secondary school completion and reduce child marriage among adolescent girls: Results from a cluster-randomised control trial in India
BACKGROUND: Secondary education and delayed marriage provide long-term socio-economic and health benefits to adolescent girls. We tested whether a structural and norms-based intervention, which worked with adolescent girls, their families, communities, and secondary schools to address poverty, schooling quality and gender norms, could reduce secondary school drop-out and child marriage among scheduled-caste/scheduled-tribe (SC/ST) adolescent girl…

Exploring the Association Between Mobility and Access to HIV Services Among Female Sex Workers in Zimbabwe
Enhancing national prevention and treatment services for sex workers in Zimbabwe: A process evaluation of the SAPPH-IRe trial
Targeted HIV interventions for female sex workers (FSW) combine biomedical technologies, behavioural change and community mobilization with the aim of empowering FSW and improving prevention and treatment. Understanding how to deliver combined interventions most effectively in sub-Saharan Africa is critical to the HIV response. The Sisters’ Antiretroviral Programme for Prevention of HIV: an Integrated Response (SAPPH-Ire) randomized controlled tr…
Mobility and sex work: Why, where, when? A typology of female-sex-worker mobility in Zimbabwe
The effect of mobility on HIV-related healthcare access and use for female sex workers: A systematic review
Trials and tribulations: Cross-learning from the practices of epidemiologists and economists in the evaluation of public health interventions
The randomized controlled trial is commonly used by both epidemiologists and economists to test the effectiveness of public health interventions. Yet we have noticed differences in practice between the two disciplines. In this article, we propose that there are some underlying differences between the disciplines in the way trials are used, how they are conducted and how results from trials are reported and disseminated. We hypothesize that eviden…
Reducing violence and increasing condom use in the intimate partnerships of female sex workers: Study protocol for Samvedana Plus, a cluster randomised controlled trial in Karnataka state, south India

Measuring implementation strength: Lessons from the evaluation of public health strategies in low- and middle-income settings
Evaluation of strategies to ensure evidence-based, low-cost interventions reach those in need is critical. One approach is to measure the strength, or intensity, with which packages of interventions are delivered, in order to explore the association between implementation strength and public health gains. A recent systematic review suggested methodological guidance was needed. We described the approaches used in three examples of measures of impl…
Competition is not necessarily a barrier to community mobilisation among sex workers: An intervention planning assessment from Zimbabwe
Women reported being most likely to support each other when confronted with serious danger but maintained high levels of competition for clients, suggesting competition at work does not represent a barrier to support. Examples of practical assistance between SWs provide entry points for our planned community mobilization activities, which aim to broaden trust and support among SWs while acknowledging their professional competition

Does the ‘inverse equity hypothesis’ explain how both poverty and wealth can be associated with HIV prevalence in sub-Saharan Africa
Whether it is relative wealth or relative poverty that drives the HIV epidemic in sub-Saharan Africa, is a controversial aspect of HIV/AIDS epidemiology. We suggest that the social epidemiology of HIV in Africa is changing. Previously, new infections were more rapidly acquired by those of relatively higher socioeconomic position (SEP). More recently, those of relatively low SEP are at greater risk. If confirmed, we further suggest in this paper t…
