Employing the General Health Questionnaire as a Health Assessment Tool for Personnel in High Functional Occupation

Background: Psychological well-being is a fundamental aspect of overall health, particularly for individuals in high-functional occupations (HFOs). These demanding environments present unique stressors, including social isolation, extreme conditions, and high-stakes duties, contributing to a heightened prevalence of stress-related disorders. Effective assessment tools are critically needed to identify and mitigate mental health challenges proactively within this population to ensure mission readiness and personnel safety. Aims and Objectives: This study aimed to evaluate psychological stress prevalence among HFO personnel across diverse operational platforms and investigate its associations with occupation-related factors, demographics, and health habits. Materials and Methods: A cross-sectional study included 508 HFO personnel. Psychological stress was measured using the validated General Health Questionnaire-12 (GHQ-12). Demographic, occupational, and health habit data were also collected. Statistical analyses included Chi-square tests, multiple regression, and exploratory factor analysis, adhering to ethical guidelines. Results: The study found that 17.51% ( n =89) of the participants reported psychological distress (GHQ-12 score > 24). Significant associations were identified between psychological distress and seniority (lower seniority groups showing higher distress), qualification level (Level-I personnel having significantly higher distress), and duration of service (higher prevalence in those serving up to 12 months). Personal health habits, including regular alcohol consumption, smoking, and tobacco/gutka use, also showed significant links with psychological distress. Multiple regression analysis confirmed seniority and qualification as significant independent predictors. Exploratory factor analysis revealed four distinct factors collectively explaining 60% of the total variance, highlighting complex, multidimensional influences on psychological well-being. Conclusion: A substantial prevalence of psychological stress exists among HFO personnel, influenced by occupational, demographic, and behavioral factors. The GHQ-12 proved a useful screening tool. Targeted interventions are essential to enhance personnel well-being and operational effectiveness.
