Introduction
Implementation Mapping (IM) has increasingly been used for the design and/or selection and tailoring implementation strategies to promote the effective translation of evidence-based interventions into practice. IM is a tool for guiding the systematic, iterative, step-by-step design process that helps guide the co-creation of theory-bas...
To nuance the discussion on the suggested absence of the risk-compensation phenomenon in times of COVID-19.
In many countries, behavioral restrictions for COVID-19 prevention started with asking people to stay 1.5 m away from each other. To further prevent the spread of the virus, governments made it mandatory for people to wear facemasks in situat...
Terror Management Theory (TMT) proposes that when people are made aware of their own death, they are more likely to endorse cultural values. TMT is a staple of social psychology, being featured prominently in textbooks and the subject of much research. The implications associated with TMT are significant, as its advocates claim it can partially exp...
Background. Hypertension (HTN) is a growing public health concern affecting both economically developed and developing nations. In Ghana, HTN significantly impacts morbidity and mortality. Understanding the perspectives of HTN patients regarding its causes and treatment can enhance HTN management. This study explored patient perspectives on HTN in...
Weight bias internalization (WBI), the process of internalizing negative attitudes and stereotypes towards overweight individuals, significantly impacts self-worth and health behaviors, such as exercise avoidance. In the current study, we focused on the mediating role of fitness-related self-conscious emotions, particularly shame and guilt. A cross...
Introduction
Over the last decade, hypertension (HPT) is among the leading causes of death and morbidity in Ghana. In recent past, most health policy research in Ghana and Africa focussed on communicable diseases. In recent times, Ghana and other developing nations have shifted their attention to non-communicable diseases because most of these coun...
COVID-19 brought significant changes to the role of school nurses, necessitating the development of remote health education programs. However, there is a lack of evidence and pedagogical lessons for digitally transforming education for socially vulnerable children. This qualitative study analyzes the health educational needs and barriers faced by c...
Since the COVID-19 pandemic, the demand to study and work from home has become of great importance. While recent research has provided evidence for the negative influence of remote studying on the mental and physical health of students, less is known about digital well-being interventions to mitigate these effects. This study had two objectives: 1)...
The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset – with data collected between 2020 and 2022 – to asse...
We examine whether information about a female candidate’s relationship history, obtained from social media profiles, affects evaluations of her suitability for a student union board position. Moreover, we investigate whether it is possible to mitigate any bias against women with multiple partners by providing information about the origins of prejud...

In March 2020, the Your COVID-19 Risk tool was developed in response to the global spread of SARS-CoV-2. The tool is an online resource based on key behavioural evidence-based risk factors related to contracting and spreading SARS-CoV-2. This article describes the development of the tool, the produced resources, the associated open repository, and...
Current research funding models for health psychologists tend to be biased toward support for large-scale ‘definitive’ behavioural trials. This approach emphasizes rigorous tests of one or more key questions, but, unintentionally, may lead to the funding of interventions that are based on myriad untested assumptions. We propose that future funding...
