Cancer is a leading cause of death worldwide, responsible for an estimated 9.9 million
deaths in 2020. Many cancers can currently be prevented by avoiding risk factors,
implementing evidence-based prevention strategies, and adopting healthy behaviours.
Adolescence is a critical period for establishing these behaviours, as many risk
behaviours such as smoking and poor diet begin at this stage. Despite numerous
school-based interventions, significant gaps remain in achieving sustainable health
behaviour changes among adolescents.
The SUNRISE project aims to bridge these gaps and reduce social inequalities in primary
cancer prevention among adolescents in Europe. Traditional health promotion programs face
barriers such as the need for extensive resources and continuous support for educators.
Digital interventions offer a promising solution by providing cost-effective, engaging,
and tailored content accessible 24/7. As part of its comprehensive approach, SUNRISE
seeks to test various innovative solutions, including the SmartCoach program, to
determine the most effective strategies for adolescent health promotion.
SmartCoach, developed by Swiss Research Institute for Public Health and Addiction (ISGF),
is a mobile phone-based life-skills training program designed to prevent substance use
among adolescents. It has shown significant long-term effectiveness in reducing tobacco
smoking and cannabis use. Based on Social Cognitive Theory, SmartCoach promotes
self-management skills, social skills, and substance use resistance through tailored
weekly text messages over a period of several months.
Adolescence is a period of significant biological, psychological, and social transitions.
These transitions provide opportunities for skill development but also present risks for
developing harmful behaviours. Substance use often begins during adolescence, with
increased prevalence of alcohol, tobacco, and cannabis consumption as teen's age. For
instance, the Health Behaviour in School-aged Children (HBSC) study showed noticeable
increases in the lifetime prevalence of these substances among 11-to-15-year-olds.
Schools are ideal settings for delivering preventive interventions due to their
accessibility to young people.
Life-skills training programs, which focus on self-management, social skills, and
substance use resistance, have proven effective but face challenges in implementation and
sustainability. Traditional face-to-face interventions require substantial resources and
commitment from educators. Digital interventions, such as those delivered via mobile
phones, can overcome these obstacles by providing flexible, engaging, and tailored
content.
SmartCoach addresses key concepts of Social Cognitive Theory, such as outcome
expectations, self-efficacy, observational learning, facilitation, and self-regulation.
The program in its previous version provided:
Automated Messaging: 2-4 messages per week focusing on self-management skills,
social skills, and substance use resistance.
Interactive Features: Quizzes to tailor behavioural plans, friendly competitions to
incentivize engagement, and integration with social media platforms like YouTube.
A cluster-randomized controlled trial in Switzerland showed high acceptance and promising
effectiveness of SmartCoach among secondary and upper secondary school students, with
significant longer-term reductions in tobacco- and cannabis use prevalence. Active
program engagement was stimulated by interactive features such as quiz questions, message
and picture contests, and the integration of a friendly competition with prizes, where
users collected credits with each interaction.
Popular online social media platforms (e.g., WhatsApp, YouTube, TikTok) play a
significant role in young people's lives and offer powerful spaces to reach them and
influence their health. These platforms provide interactive functionalities and have
great potential for user engagement and retention. Health behaviour change interventions
using social media have shown modest evidence of effectiveness, and there have been calls
to strengthen research targeting adolescents and the sustainability of their behaviour
changes in the longer term. An automated WhatsApp-based coaching program for smoking
cessation developed by ISGF provides a foundation for further development within the
SUNRISE project.
SmartCoach will be enhanced within the SUNRISE project by leveraging the interactive and
engaging features of social media platforms. Adolescents spend a considerable amount of
time on platforms like WhatsApp, YouTube, and TikTok, making these platforms ideal for
delivering health interventions. By integrating SmartCoach with these social media
platforms, the program aims to increase engagement, retention, and effectiveness.
For instance, WhatsApp can be used to send automated messages and provide a communication
channel for adolescents to interact with addiction experts. YouTube and TikTok can be
used to share engaging multimedia content that promotes healthy behaviours and provides
educational resources about cancer prevention. These platforms can also facilitate peer
support and create a community of adolescents who are committed to adopting healthier
lifestyles.
By integrating digital tools and leveraging social media, SmartCoach aims to create a
more engaging, effective, and sustainable intervention for adolescent health behaviour
change. The focus is primarily on preventing substance use and promoting healthy
lifestyles to reduce the risk of cancer. The SUNRISE project seeks to bridge existing
gaps in adolescent health promotion, reduce social inequalities in primary cancer
prevention, and become a reference point in Europe and beyond for adolescents, their
parents, educators, and public health experts.
The SUNRISE project and the SmartCoach program represent a significant step forward in
the primary prevention of cancer among adolescents. By addressing the challenges of
traditional health promotion programs and leveraging the power of digital interventions,
these initiatives aim to create lasting health behaviour changes that will reduce the
risk of cancer and improve overall health outcomes for future generations.
