Realistic Evaluation of Expériences Animées, a School-based Intervention in Nouvelle Aquitaine

The study is a realistic evaluation of the Expériences Animées school-based programme. The aim is to precisely characterize i) the effects in terms of alcohol and cannabis consumption, the use of health professionals in case of problematic use of those two substances; ii) the context and underpinning mechanisms triggered by the program in terms of changes of alcohol and cannabis representations and life skills development. This evaluation could allow to produce the key functions of the programme: how the intervention works, in which conditions.

About this study

  • Alcohol consumption represents the second main modifiable risk factor for cancer and the second preventable mortality cause in France, after tobacco use. It is mainly during adolescence, which corresponds to a period of integration with peers and a period of detachment from parents, that alcohol use starts. In France, alcohol remains the substance that adolescents most experiment with. A 2014 report shows that nearly half (49.4%) of first-year secondary school pupils have already tried an alcoholic drink and about one in seven secondary school pupils' reports having been drunk. The impact of cannabis consumption is wide as it can affect the social environment, the brain and the psychology of the consumers. Adolescence is a period during which the brain undergoes profound remodelling in areas that are high in cannabinoid receptors and that mediate cognitive control and emotion regulation. Therefore, childhood and adolescence are important stages of life on which preventive efforts may be focused, also because events occurring in the earliest stages of human development (before birth and during childhood) are known to be related to further risk for cancer, other chronic diseases and adult conditions.
  • Among addiction prevention programmes, those that focus on life skills have been mentioned in the literature as being effective. In this context, the French organization "Association Ressources et Initiatives Addictions" (ARIA) has developed Expériences Animées programme (animated experiences) based on the above features, with the aim to help adolescents to change their representations and strengthen their life skills. This is a grassroots innovation. It has to be evaluated.
  • The Expériences Animées programme involves supervised short movies and talks with secondary and high school pupils about the use of psychoactive substances. The movies are made specifically for the programme. The sessions are facilitated by two professionals including at least a clinical psychologist. In a given secondary/high school, one session per term is delivered for each class (40 classes). Three to five films are shown at each session. Each film aims to work on 2 to 3 life skills allowing to build protective behaviors against addictions. This programme is implemented since 2015.
  • The investigators will collect quantitative and qualitative data to appraise the outcomes (O), mechanisms (M) and contextual elements (C), including the interventional elements) in order to verify the initial theories (hypothesis of causal pathways) by i) Questionnaires to collect outcomes in terms of consumption and health care, and some mechanisms: 2/ Non-directive interviews to collect mechanisms and contextual factors 3/ Observations to collect contextual elements during the sessions. The investigators will design the survey instruments in line with the initial middle-range theories identified.
