Completed key studies

Determinant studies
For intervention development to be effective, an identification and in-depth understanding of the behavioural, environmental and other determinants is required. By unpacking the determinants, targeted interventions to change or promote certain determinants of behaviour can be developed. This also allows for a systematic measurement or evaluation of the effectiveness of the intervention. A number of our studies are mentioned below:

• A qualitative access point analysis with educators regarding their perceptions of tobacco-use prevention interventions in schools
• A qualitative assessment of Xhosa speaking girls' understanding of resilience to tobacco-use
• Towards a smoke-free university: Smoking status, knowledge of health effects and opinions on regulation of smoking among staff and students in an academic institution in South Africa
• A qualitative study to explore the determinants of smoking cessation among school going adolescents in South Africa
• A survey of the determinants of smoking cessation among school going adolescents in South Africa
