Perceived Threat Scale

Scale in the Deployment Risk and Resilience Inventory-2
DRRI-2 Section: G
Survey Label: "Deployment Concerns"


Fear for one's safety and well-being during deployment, especially as a response to potential exposure to warfare (e.g., attacks by enemy combatants, encountering explosive devices), as well as nuclear, biological, and chemical agents (NBCs) in the war zone (e.g., depleted uranium in munitions, pesticides, or other routinely used chemicals). This factor reflects emotional or cognitive appraisals of situations that may or may not accurately represent objective or factual reality.

Sample Items

  • I was concerned that I would encounter an explosive device (for example, a roadside bomb, mine, or booby trap).
  • I was concerned that I might be exposed to depleted uranium in munitions.
  • I was concerned about being trapped in the crossfire of rival factions.

Response Format

5-point Likert (1 = Strongly disagree; 5 = Strongly agree)
