Acceptability, Feasibility, and Effects of a Mindfulness-Based Intervention on the Quality of Life and Performance of the Brazilian Paralympic Boccia Team: Mixed Methods Case Study

This study evaluated the acceptability, feasibility, and effects on the quality of life and performance of a mindfulness-based intervention (MBI) for the Brazilian Paralympic Boccia Team. A longitudinal quasi-experimental intervention case study design was used with evaluations before and after applications. A mixed design with quantitative and qualitative instruments was applied for 29 participants categorized as ATHLETE and NON-ATHLETE. Mindfulness training consisted of eight one-hour sessions with a four-hour 1st CYCLE, a four-hour 2nd CYCLE, and three follow-up evaluations (one, six, and 12 months after the baseline) with 10 maintenance sessions. Participants underwent an improvement of quality of life and performance associated with a significant increase in attention levels. Regarding acceptability and feasibility, the MBI showed high levels of participant compliance, satisfaction, and recommendation for use in Paralympic contexts. These findings suggest that mindfulness interventions can be a viable strategy for promoting psychological resilience and enhancing competitive performance in Paralympic athletes.
