Evaluating Occupational Stress in Surgeons and Musicians: A Multi-modal Pilot Study Using Wearable EEG, Biomarker Analysis and Validated Questionnaires

Primary Objectives • To assess the change in occupational stress among surgeons and musicians by measuring physiological and psychological stress markers. Endpoints: * Changes in salivary cortisol levels (before and after surgeries for surgeons and live public performances for musicians). * Changes in State-Trait Anxiety Inventory-Short (STAI-S) scores (administered pre- and post-surgery/performance). SECONDARY OBJECTIVES AND ENDPOINTS • Assessing and comparing anxiety and burnout, based on the MBI, STAI-T, M-PAS, and SCAT, in surgeons and musicians Endpoints: * Baseline levels of anxiety and burnout measured using the MBI, M-PAS, STAI-T, and SCAT. * Emotional exhaustion, depersonalization, and personal accomplishment from the MBI in both groups.
