Plain English summary of protocol
Background and study aims
Early psychoactive substances consumption (PSC) in youth impairs psychosocial and neurocognitive development with with short- and long-term consequences (Hamidullah et al., 2020; Castellanos-Ryan et al., 2017). Among French teenagers, lifetime use (experimentation) of tobacco and alcohol, and to a lesser extent cannabis, still begins in the early years of middle school, with an increase and installation of consumption in the transition to high school (Kopp, 2023 ; Obradovic, 2022).
Few prevention of PSC programs are evaluated, and heterogeneous effects of actions, with rare or limited replication are found (Santé Publique France, 2019, Tremblay et al., 2020). This lack of replicability is consistent with the low quality of theoretical implementation (Michie, 2014). The COM-B (Michie et al., 2011) appears as a key theoretical framework for understanding and supporting behavior change, and for designing and informing interventions, by choosing appropriate behavior change techniques (BCT, Michie et al., 2013). The use of technology, and in particular gaming, can enhance students interest in learning (Virvou et al., 2005) with interventions build on immersive, enjoyable, problem-based principles, and strategies that encourage health behavior change (Stapinski et al., 2018).
Escape Addict (EA) was first implemented in Switzerland, and designed as an escape game. Evaluations (Bezençon et al, 2022 ; Bezençon et al., 2023) reported that the one hour and a half experience was not sufficient to lead to significant change in PSC representations and behaviors. A french association, in collbaoration with actors in the field and researchers, adapted EA to its cultural context, and developed supplementary sessions to complete the game and foster behavior change basing the intervention on the COM-B model, integrating relevant BCT and using relevant prevention tools to communicate about PSC.
Who can participate?
8th grade students from high schools in deprived background of Rouen Metropolis (Normandy, France) are eligible to participate.
What does the study involve?
The first objective of the pilot study is to evaluate the feasibility (acceptability, implementation, fidelity) of EA program ; The second objective of the study is to estimate the pilot effect-size of EA on the retardation of first experience and on the decrease of recent PSC. The PSC targeted by EA are alcohol, cannabis, tobacco and chicha ; outcomes are assessed by questionnaire at two study endpoints (baseline-post). The primary outcome is the proportion of adolescents who did not experience psychoactive substances. The secondary outcome is the proportion of adolescents who decreased their recent PSC (last month consumption). Other outcomes are motivational variables determining behavior change, assessed by COM-B questionnaire.
The study will include secondary schools from disadvantaged backgrounds in the Rouen metropolitan area. 4 secondary schools 8th grade classes (around n = 300 students) will benefit from EA program. To investigate feasibility, a mixed method study, with quantitative indicators, and qualitative study based on process analysis and FIC model (Key Functions/Implementation/Context, Villeval, 2015) will be used, the latter allowing, in particular, to analyze the effects of the intervention in terms of social inequalities. Interviews and focus group will involve various actors engaged in the intervention (schoolchildren, school nurses, teachers, prevention staff, research and field team).
What are the possible benefits and risks of participating?
The expected impacts are to develop a theoretically anchored, playful public health program in high school, targeting PCS, that is acceptable, easily implemented and adapted to students’ social backgrounds. The benefits for participants are, with a decrease or delay of PSC use, also the improvement of psychosocial skills (i.e. psychosocial variables influencing behaviour, targeted by the model).

Scientific title | Escape Addict : pre-post pilot effectiveness and feasibility study of a playful theory-based secondary school prevention program to delay and decrease psychoactive substances consumption in schoolchildren from Normandy |
Study acronym | Escape Addict-Feasibility |
Study objectives | Escape Addict (EA): 1. Is a feasible program, that is acceptable for both targeted populations and people implied in program implementation, useful, interesting and answer a demand and that can be successfully delivered 2. Demonstrates, at least, a weak to moderate effect on targeted behaviors: delay first experience of PSC and decrease PSC in adolescents from deprived background 3. Influence determinants the COM-B model that lead to behavior change: Capability, Opportunity and Motivation to decrease/not to use psychoactive substances in adolescents from deprived backgrounds |

Health condition(s) or problem(s) studied | Prevention of psychoactive substances use among healthy schoolchildren |
Intervention | Escape Addict is a playful school-based prevention program (based on an escape game), and theoretically anchored in a behavior change model (COM-B, Michie et al., 2011, and Behavior Change techniques, BCT, Michie et al., 2014). It aims to delay and reduce the use of psychoactive substances (alcohol, cannabis, tobacco and chicha) by middle-school students (8th grade, 14-year-olds) from disadvantaged areas in Normandy (France). The program involves students, school staff and parents, and takes place in 4 stages a. Discovery of the tool by members of the educational community b. Preparation of the co-leadership of the student sessions and teasing of the students c. Carrying out the 4 sessions of the program with the students d. Carrying out the session with the parents and debriefing. These sessions can be deployed throughout the school year. |
Intervention type | Behavioural |
Primary outcome measure | The proportion of adolescents who did not experience psychoactive substances assessed by questionnaire at baseline and 6 months |
Secondary outcome measures | The proportion of adolescents who decreased their recent (i.e. last month) PSC consumption measured using questionnaire at baseline and 6 months later |
Overall study start date | 16/01/2023 |
