Introduction
I study social-cognitive and environmental influences on health behaviour, especially in young people. My research expands across contexts but focuses on Sub-Saharan Africa. I have worked in academic and applied health institutions in Greece, Britain, South Africa, the USA, and Australia. I am a member of the British Psychological Society (CPsychol, AFBPsS), The European Health Psychology Society, and a Fellow of The Higher Education Academy, UK.

Good sleep is essential for health but there is no consensus on how to define and measure people's understanding of good sleep. To date, people's perceptions of a good night's sleep have been, almost exclusively, conceptualized under the lens of sleep quality, which refers to objective characteristics of good sleep, such as such as ease and time ne...
Article
Full-text available
The adoption of carbohydrate-restrictive diets to improve health is increasing in popularity, but there is a dearth of research on individuals who choose to severely restrict or entirely exclude carbohydrates. The present study investigated the beliefs and experiences of individuals following a diet that severely limits, or entirely excludes, dieta...
Preprint
Full-text available
Background: While predominant dietary guidelines promote foods low in fat and high in carbohydrates, evidence links high carbohydrate consumption to adverse health effects in populations that are metabolically challenged by (pre)diabetes or metabolic syndrome. An increasing number of people report eating diets that limit carbohydrates. These diets...

Study quality is emerging as an essential component of evidence syntheses and allows practitioners and policymakers to make informed decisions based on the quality of the evidence reviewed. Study quality is typically assessed by checklists of pre-determined quality criteria. Few study quality checklists have been systematically evaluated, and none...
Article
Full-text available
Self-regulation is a key antecedent of health and behaviour-change interventions have utilized self-regulation approaches to promote health. The present study used a novel methodology, a nested meta-review, to: (a) integrate and summarize information from evidence syntheses of diverse self-regulation interventions to reduce risk-taking, in the beha...
Preprint
Full-text available
In this Opinion article, we argue that assessment of study quality is an important practice to promote greater precision, transparency, and evaluation of research in psychology. However, no quality appraisal tools have been developed by psychologists, for psychological research. Given the prominence of survey research in psychology, the development...

Self-determination theory has been applied to understand the role of affect in motivation and behavior in health contexts. According to self-determination theory, autonomous forms of motivation, reflecting self-endorsed reasons for acting and the satisfaction of psychological needs, are related to participation and persistence in health behavior. R...

Background: Sub-Saharan African nations continue to carry the substantive burden of the HIV pandemic, and therefore, condom use promotion is a public health priority in that region. To be successful, condom promotion interventions need to be based on appropriate theory. Objective: To develop and test an integrated theory of the determinants of youn...
Article
Full-text available
Objective. Synthesizing research on social cognitive theories applied to health behavior is an important step in the development of an evidence base of psychological factors as targets for effective behavioral interventions. However, few meta-analyses of research on social cognitive theories in health contexts have conducted simultaneous tests of t...
Article
Full-text available
Objective: We aimed to develop an integrated theoretical model of the determinants of condom use in young people from sub-Saharan African (SSA) nations. Model development was informed by research predicting condom use in SSA nations adopting individual-level social-cognitive and socio-ecological theories, and guided by McMillan and Conner's (2007)...

Background: Religiosity is a resource for safer-sex behaviour in HIV pandemic regions. We investigated influences of personal and parental religiosity on safer-sex behaviours among Botswana Pentecostal youth. Methods: 261 youth (female = 65%) from a major Pentecostal Church in Botswana completed the Botswana Youth Health Survey (BYHS). The BYHS inc...
Conference Paper
Background: Given the very limited available data, this study this study aimed to determine the applicability of the Theory of Planned Behaviour (TPB: Ajzen, 1991) in the study of high-fat snacking in Greek high-school students, whilst taking into consideration gender and culture-relevant factors. Methods: Predictor variables were measured at Time...
Article

This study was carried out among university undergraduates in Cape Town, South Africa. Structural equation models were tested with Mplus to predict intentions to use condoms and actual (subsequent) condom use. Theory of planned behavior (TPB) predictors (attitudes, subjective norms, perceived behavioral control) explained 43% of the variance of int...

Conference Paper
Background: Behavioural interventions for reducing HIV risk behaviour have been evaluated for adolescents. These trials have had conflicting results, and prior meta-analyses have not examined whether important structural dimensions account for these differences. Methods: 139 intervention trials from 22 nations were retrieved; efficacy was assessed...
Article
Full-text available
Amongst the psychological theories that have been used to help understand why people have unprotected sex, the Theory of Planned Behaviour (TPB: Ajzen 1991) has earned a prominent position. This article is a critical review of 11 peer-reviewed studies conducted in sub-Saharan Africa during 2001 to 2009, which used the TPB as a model of predicting s...

Project
The Noakes Foundation's AFSDV theme supports two main projects- (i) online academic bullying (OAB) and (ii) exemplary digital voices: For (i) we have prepared a clear definition for what online academic bullying is. This definition and related case studies should prove useful for victims and policy makers who confront such uncivil phenomena online. Our research also assists academic free speech, by helping recipients of OAB to report on this emergent threat. We also suggest diverse strategies for confronting academic cyberbullies and cybermobs. Under (ii) we explore how Insulin Resistance (IR) scholars are using Twitter for promoting engagement with their research. In particular, we analyse original deliberations and conversation threads related to IR science articles that contest the dominant “cholesterol” model of chronic disease development.
Project
Background. Sub-Saharan African (SSA) nations continue to carry the substantive burden of the HIV pandemic, and therefore, condom use promotion is a public health priority in that region. To be successful, condom promotion interventions need to be based on appropriate theory. Objective. We (Cleo Protogerou, Martin S Hagger, and Blair T Johnson) are developing an integrated theoretical model of the determinants of condom use among young people in SSA using meta-analytic path analysis of research to date. The model is being developed based on generalized theoretical frameworks of social cognitive theory, and research predicting condom use in SSA nations adopting individual-level social-cognitive theories. Method. Meta-analysis of research on social-cognitive predictors of condom use in young people in SSA. Identification of key moderators of the effects of theoretical antecedents on condom use, including assessments of methodological quality. Expected results. The integrated theoretical model will describe, explain, and predict condom use among young people in SSA. The model will provide an evidence- and theory-based guide to future research examining the antecedents of condom use in young people in SSA. The model may assist in developing targets for effective condom promotion interventions in this population. Funding for this research was provided to Cleo Protogerou (PI) by the Berkeley Initiative for Transparency in the Social Sciences, a program of the Center for Effective Global Action (CEGA), with support from the William and Flora Hewlett Foundation.
