Interventions efficaces en psychologie positive: Une revue systématique.

Abstract

This systematic review has a public health policy perspective and aims to evaluate the effectiveness of positive psychology interventions in non-clinical populations. Studies—from articles, theses or book chapters—and published between 2005 and 2016, had to be based on experimental studies of self-administered interventions directed at the population at large, include at least one measure of well-being or depression, and aim to improve well-being. A total of 36 papers were selected, including three reviews. In the vast majority of cases, consistent with the existing literature reviews on positive psychology interventions, the interventions lead to reductions in anxio-depressive symptoms, as well as increases in well-being. While the effect sizes are modest, parameters or conditions that may influence the effectiveness of the interventions are reported, such as the characteristics of the exercises, the participants and their adequacy. In conclusion, while the favourable impact of these interventions is generally low or moderate, their usefulness remains important considering their large-scale development and low cost.
