We examine the effectiveness of behaviour change techniques (BCTs) within mobile phone apps designed to improve health behaviours. One study focuses on physical activity apps in China, assessing their quality and the BCTs employed. Another investigates BCTs in self-harm apps for young people, identifying prevalent techniques and their theoretical underpinnings. A third study conducts a meta-analysis of interventions for increasing physical activity and healthy eating in adults, exploring which BCTs predict both short and long-term success. Finally, a fourth study analyses the effectiveness of BCTs in interventions to reduce sugar-sweetened beverage consumption among disadvantaged adolescents.
