Organizational affective commitment effects on militaries' well-being during a deployment: A study of a peacekeeping mission.

Based on the Conservation of Resources Theory, this longitudinal study analyzes the contribution of organizational affective commitment during the preparation phase of a peacekeeping mission (T1) to explain the well-being of soldiers during that mission (T2). A sample of 409 Brazilian army participants in the MINUSTAH (United Nations Stabilization Mission in Haiti) was used in two waves - preparation of the troops in Brazil, and their deployment in Haitian territory. The data analysis was performed using structural equation modeling. The results supported organizational affective commitment during the preparation phase (T1) positively predicting the general well-being (perception of health and general satisfaction with life) of these soldiers during the deployment phase (T2). The workplace well-being (i.e. work engagement) of these peacekeepers was also found to mediate this relationship. Theoretical and practical implications are discussed, and limitations and suggestions for future research are presented.
