Résumé
Musicians’ performance experiences range widely, from elation to severe anxiety. In this study, we examined musicians’ performance experiences through the lens of the biopsychosocial model of challenge and threat. According to this model, a challenge state arises when perceived resources meet or exceed perceived demands, while a threat state occurs when demands outweigh resources. These states can be quantified using the Demand Resource Evaluation Score (DRES), calculated as the difference between resource and demand evaluations, with higher values indicating a greater challenge-type response. Although post-event processing is a key factor in maintaining social anxiety, research on factors influencing musicians’ post-performance thoughts remains limited. Additionally, the link between DRES and post-performance thoughts is unknown. This study aimed to determine (1) how DRES is influenced by the general music performance anxiety (MPA) level, audience presence, and time (pre-performance vs. during-performance); (2) how negative and positive post-performance thoughts are influenced by general MPA level and audience presence; and (3) whether DRES predicts post-performance thoughts.
