Abstract:

This study examined whether positive and negative affect were associated with the relationship between psychological capital and quality of work life among maritime education instructors. This study addresses a research gap: limited empirical evidence on these variables in maritime education. This study employed a quantitative, cross-sectional design involving 50 maritime education instructors from PNTC Colleges. Data were collected using three standardized psychological instruments and analyzed using mediation analysis. The results indicated that the participants exhibited very high levels of psychological capital, high quality of work life, high positive affect, and low negative affect. Regression analyses showed that psychological capital was not significantly associated with positive affect, negative affect, or quality of work life. Furthermore, the indirect effects of psychological capital on quality of work life through positive affect and negative affect were not statistically significant. The indirect effect through positive affect was (B = 1.51, 95% CI [-.704 to 4.57]), while the indirect effect through negative affect was (B = 0.08, 95% CI [-1.79 to 1.27]). Positive affect, however, was significantly associated with higher quality of work life. This study contributes to the literature by providing empirical evidence on psychological capital, affect, and quality of work life among maritime education instructors. The findings may inform higher education institutions offering maritime programs in developing evidence-informed initiatives that support instructors' psychological well-being and work experiences.
