This study examined the relationship between spiritual intelligence (SI), emotional intelligence (EI), coping ability (CA), and burnout (BO) among humanitarian aid workers in Zimbabwe. A convenience sample of 296 (53% males and 47% females) humanitarian aid workers was used in the study. Correlation and multiple regression analyses were used to explore the contribution of SI, EI, and CA to the burnout. Results indicated that SI, EI, and CA are all significantly related to Burnout and its dimensions of emotional exhaustion (EE), depersonalisation (DP) and personal accomplishment (PA) in humanitarian aid workers. CA and EI significantly contributed to the variation of scores in EE and DP whereas SI did not. However, all the three variables significantly contributed to the variation in PA. Gender, age, employment status and tenure in NGO had no significant relationships with EE, DP, or PA whereas contract type, length of service, educational level and nature of work were associated with statistically significant differences in EE, DP, and PA. The research contributed to the understanding of burnout among aid workers in Zimbabwe. Humanitarian organisations can use the findings to come up with scientifically backed recruitment, selection, training, and staff wellbeing policies and programmes that help to reduce the impact of burnout in the humanitarian aid sector. / Psychology / D.
