Imagerie mentale de la meilleure version de soi possible et activation comportementale.

Abstract

Objectives: Our study aimed to evaluate the potential benefits of combining mental imagery of the best possible self (BPS) with reflection on personal values to facilitate behavioral engagement, improve optimism, and promote well-being. The BPS intervention was compared to a control condition (lemon mental imagery). Methodology: First, participants were asked to plan activities for the next two weeks. Then, participants in the experimental group (BPS) wrote and imagined their best possible self, focusing on the goals they would like to achieve in three domains (personal, professional, and relational). Meanwhile, participants in the control group imagined manipulating a lemon. All participants were then instructed to practice the mental imagery exercise daily for two weeks and engage in the planned activities. The effects on behavioral activation, optimism, and psychological well-being were measured at three points: before the intervention, after two weeks of intervention, and finally after one month without intervention. Results: The results indicated a nonsignificant effect of the BPS intervention on the various psychological variables. However, significant results were observed regarding "Time", "Condition", and the "Nature of the activity". Various factors could be responsible for these results. Limitations: This study is subject to limitations, including a small sample size and the nature of the control condition. Strengths: This study is introduced participants to a novel approach. Furthermore, the BPS intervention is flexible in terms of delivery method and can be effective both in-person and online settings (Loveday et al., 2018).
