Background: Understanding links between behaviour change techniques (BCTs) and mechanisms of action (the processes through which they affect behaviour) helps inform the systematic development of behaviour change interventions. Purpose: This research aims to develop and test a methodology for linking BCTs to their mechanisms of action. Methods:...

As more behavioral health interventions move from traditional to digital platforms, the application of evidence-based theories and techniques may be doubly advantageous. First, it can expedite digital health intervention development, improving efficacy, and increasing reach. Second, moving behavioral health interventions to digital platforms presen...

Ontologies are ways of representing aspects of the world in terms of uniquely defined classes of ‘entities’ and relationships between them. They are widely used in biological science, data science and commerce because they provide clarity, consistency, and the ability to link information and data from different sources. Ontologies offer great promi...

Social mixing contributes to the transmission of SARS-CoV-2. We developed a composite measure for risky social mixing, investigating changes during the pandemic and factors associated with risky mixing. Forty-five waves of online cross-sectional surveys were used (n = 78,917 responses; 14 September 2020 to 13 April 2022). We investigated socio-demo...

Psychological distress has been elevated during the COVID-19 pandemic. However, few studies published to date have investigated distress after the first wave of infections (Spring – Summer 2020). We investigated distress and wellbeing between April 2020 and April 2022 in England through a series of cross-sectional online surveys. People aged 16 yea...

Article
Since the start of the covid-19 pandemic, in the UK and elsewhere, the phrase “living with covid”—and variations such as “live with it,” “learning to live with the virus”—has circulated in public discourse. It refers to, and summarises, increasingly polarised positions with regards to the pandemic: on the one hand, accept the virus and resist adapt...

Introduction: The UK low-risk drinking guidelines were revised in 2016. Drinkers were primarily informed about the guidelines via news media, but little is known about this coverage. This study investigated the scale and content of print and online textual news media coverage of drinking guidelines in England from February 2014 to October 2017. M...

Introduction The inappropriate use of antibiotics is a key driver of antimicrobial resistance. In China, antibiotic prescribing and consumption exceed recommended levels and are relatively high internationally. Understanding the influences on antibiotic use is essential to informing effective evidence-based interventions. We conducted a scoping rev...
Article
Background Blood transfusion is a common but costly treatment. Repeated national audits in the UK suggest that up to one-fifth of transfusions are unnecessary when judged against recommendations for good clinical practice. Audit and feedback seeks to improve patient care and outcomes by comparing clinical care against explicit standards. It is wide...

We aim to identify influences on UK citizens’ household food waste recycling as a basis for designing strategies to increase household food waste collection rates via local services. Using a UK dataset (n = 1801) and the COM-B (Capability–Opportunity–Motivation–Behaviour) model as a theoretical framework, we conduct quantitative regression and supp...
Article
The COVID-19 pandemic highlighted the vital importance and impact of human behaviour on viral transmission. During 2020, large amounts of global survey data were collected and made freely available to help the response. Many teams responding to the pandemic lack capacity to interpret and apply behavioural data. A collaboration of the World Health O...
Article
Importance: Auditing and feedback are frequently used to improve patient care. However, it remains unclear how to optimize feedback effectiveness for the appropriate use of treatments such as blood transfusion, a common but costly procedure that is more often overused than underused. Objective: To evaluate 2 theoretically informed feedback inter...
