The Impact of a Psychological Skills Training and Mindfulness-Based Intervention on the Mental Toughness, Competitive Anxiety, and Coping Skills of Futsal Players-A Longitudinal Convergent Mixed-Methods Design.

Despite the sport's popularity, there is a paucity in futsal psychological interventional research. This study analysed the impact of a ten-session psychological skills training and mindfulness-based intervention (PSTMI) on the mental toughness, competitive anxiety, and athletic coping skills of national league futsal players (n = 13). It also analysed whether these variables were predicted by playing experience. Pre-/post-intervention questionnaires were filled in and analysed (Competitive State Anxiety Inventory-2, Sport Mental Toughness Questionnaire, and Athletic Coping Skills Inventory-28). Semi-structured interviews were also conducted with seven athletes; quantitative and qualitative data were integrated in a convergent parallel mixed-methods design. Results revealed significant medium-to-large improvements in mental toughness, cognitive anxiety, and coping skills following the PSTMI. Years of playing experience positively and significantly predicted better self-confidence and coping skills. Thematic analysis generated five themes: (1) post-intervention enhancement in athletic performance and well-being; (2) the non-athletic commitments of futsal players; (3) diverse views on how to improve the intervention; (4) instilling social identity through sport psychology sessions; and (5) the impact of years of experience on skill learning. Results mirrored those from other sporting disciplines. The PSTMI was well-received and equipped athletes with beneficial psychological skills, stressing the need for more sport psychology resources in futsal.
