Maria is a middle‑school principal. At the start of the year she feels energetic, but as months pass the workload piles up: meetings, deadlines, parent requests, and administrative decisions. A research team followed her closely for an entire school year. They recorded sleep quality, mental‑well‑being levels, and health habits, and interviewed her four times while observing two workdays. The data show that, although stress sometimes felt motivating, the buildup of tasks and systemic challenges began to weigh on her health and confidence in leadership. Maria judged stress based on how much control she had, the problem’s complexity, and how well it matched her professional expectations. When control dropped, stress grew heavier. The study suggests principal‑training programs should teach stress‑management strategies, good sleep hygiene, and resilience tools. Moreover, school districts should build support networks for leaders, preventing stress from becoming a barrier to health and education quality.
The study employs a mixed‑methods approach, merging quantitative measurements (sleep quality questionnaires, psychological well‑being scale, leadership self‑efficacy index) with qualitative data (semi‑structured interviews, ethnographic observations). Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), yielding a global score from 0 to 21; scores above 5 indicate sleep disturbances. Mental well‑being was measured with the Warwick‑Edinburgh Mental Well‑Being Scale (WEMWBS), capturing positive aspects of emotional experience. Leadership self‑efficacy was quantified via the Leadership Self‑Efficacy Scale (LSES), exploring the principal’s confidence in handling complex tasks, delegating, and making strategic decisions. Interview analysis identified four key dimensions in stress appraisal: perceived control, agency (capacity to act), stressor complexity, and alignment with professional expectations. These dimensions were correlated with changes in sleep and well‑being scores, revealing a significant relationship between loss of control and sleep quality deterioration (r = -0.62, p < .05). Moreover, longitudinal analysis showed that stress accumulation reduced leadership self‑efficacy by roughly 15% from the baseline. Findings suggest targeted interventions—mindfulness programs, leadership coaching, and administrative load reduction—could mitigate cumulative stress effects. Finally, the study emphasizes a systemic approach: interventions must extend beyond the individual principal to redesign organizational structures and human‑resource practices at the district level, fostering a more resilient and sustainable educational environment.
