Abstract
This study examined the relationship between workload and stress levels among Filipino nurses during disaster response operations in Quezon City. Specifically, it determined the extent of workload experienced by nurses, assessed their stress levels, examined the relationship between workload and stress, and identified workload dimensions that significantly influence stress. Using a descriptive-correlational quantitative design, data were collected from 109 Filipino nurses involved in disaster response operations through a validated researcher-made survey questionnaire. Descriptive statistics, Pearson correlation, and multiple regression analyses were employed to analyze the data. Findings revealed that respondents experienced a high extent of workload across patient load (M = 4.40), working hours and shift extension (M = 4.32), task complexity and role expansion (M = 4.33), manpower and staffing support concerns (M = 4.18), and availability of medical supplies and resources (M = 4.14). Nurses also reported high stress levels in terms of physical stress symptoms (M = 4.36), psychological stress symptoms (M = 4.24), cognitive stress responses (M = 4.27), and emotional responses to disaster-related patient care (M = 4.26), while demonstrating strong coping ability (M = 4.51). Significant positive relationships were found between all workload dimensions and stress levels, with working hours and shift extension showing the strongest correlation (r = 0.727, p < .001). Regression analysis identified patient load, working hours and shift extension, and manpower and staffing support as significant predictors of stress. The study was limited to nurses involved in disaster response operations in selected areas of Quezon City. Findings highlight the need for improved workforce planning, adequate staffing, manageable shift schedules, and comprehensive mental health support programs. This study provides localized evidence on disaster-related nursing workload and stress, offering valuable insights for healthcare administrators, disaster management authorities, policymakers, and nursing professionals in strengthening disaster preparedness and nurse welfare
