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.

The purpose of this meta-review was to identify characteristics of successful HIV prevention interventions for adolescents based on quantitative (i.e., meta-analyses) and qualitative reviews published to date, and to inform intervention utilization and future development. To that end, we were guided by principles of triangulation. Searches of seven...

This study aimed to investigate contextual influences on condom use by South African university students. Twenty one-to-one, semi-structured interviews were conducted with male and female South African undergraduates. The data were thematically analysed. Res...
Cardiac surgery patients may be provided with psychological interventions to counteract depression and anxiety associated with surgical procedures. This systematic review and meta-analysis investigated whether intervention efficacy was impacted by type of cardiac procedure/cardiac event; control condition content; intervention duration; interventio...
Objective:
We tested an integrated social-cognitive model derived from multiple theories of the determinants of young people's condom use in Sub-Saharan Africa. The model comprised seven social-cognitive antecedents of condom use: Attitudes, norms, control, risk perceptions, barriers, intentions, and previous condom use.
Method:
We conducted a s...
Good, satisfying, sleep is a key indicator and determinant of health and wellness. However, there is no consensus about how to define and measure good sleep. The present research aimed to define sleep satisfaction through the extant literature and disentangle it from sleep quality, a conceptually similar construct. Systematic review methods were ad...

Dear Colleagues,
Healthcare increasingly requires accelerated access to current literature to inform decision-making, policy and practice. Emerging and/or urgent health issues demand high-quality evidence syntheses in a timely fashion to guide health system responses. Systematic reviews are considered the gold standard for collating, summarizing a...
In a meta-analysis of research on measures of the habit construct, we aimed to estimate the size and variability of habit–behavior and intention–behavior relations, and habit as a mediator of past–future behavior relations. Furthermore, we investigated the theory-consistent moderators of these relations including opportunity for habit formation and...
In this position paper, we note that appraisals of health behaviour change interventions (HBCIs) focus on identifying intervention particulars (e.g., techniques, design, theoretical underpinnings, psychological mechanisms, delivery modes) most prominently and consistently associated with desired behaviour change. However, a key aspect of interventi...
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...

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...
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...
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...
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...
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...
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...
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...
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...

This study explored culture and context-relevant factors shaping condom use in South African university students. Twenty one-to-one, semi-structured interviews were conducted (15 female, five male, aged between 18 and 25, representing six racial/cultural backgrounds). Data were coded using NVivo and thematically analysed, following guidelines of Br...
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...
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...
In this Chapter, we provide a comprehensive presentation of what is known about bullying in schools. We begin with highlighting the epidemiology and nature of bullying, and we proceed with the research findings of hypothesised antecedents and consequences of bullying. Then, we present the anti-bullying intervention programmes, along with a commenta...
This study investigated the impact of socio-cognitive factors (attitudes and norms), time perspective (TP), relationship status (RS), and past sexual behaviour on intended non-condom use in 104 Greek and 93 British university undergraduates.
Data were obtained by a self-report questionnaire. Data analysis included correlation, regression and ANOVA...
