Combat Exposure Scale (CES)

Description

The Combat Exposure Scale (CES) is a 7-item self-report measure that assesses wartime stressors experienced by combatants. Items are rated on a 5-point frequency (1 = "no" or "never" to 5 = "26+ times" or "51+ times"), 5-point duration (1 = "never" to 5 = "7+ months"), or 45-point degree of loss (1 = "none" to 45 = "76% or more") scale.

Respondents are asked to reply based on their exposure to various combat situations, such as firing rounds at the enemy and being on dangerous duty.

Administration and Scoring

The CES was developed to be easily administered and scored and is useful in both research and clinical settings. The total CES score (ranging from 0 - 41) is calculated by using a sum of weighted scores, which can be classified into one of five categories of combat exposure ranging from "light" to "heavy." Scoring instructions are included with the measure.

Sample Item

  • Item: Were you ever surrounded by the enemy?
  • Response: 5-point frequency (1 = "no" to 5 = "26+ times")
