Which of the following is NOT a criterion for PTSD eligibility?

The correct answer highlights that proof of combat engagement during service is not a necessary criterion for eligibility for PTSD under VA standards. While evidence of combat service can strengthen a claim and may provide a basis for presumed stressors, it is not a prerequisite for establishing PTSD.

To qualify for PTSD benefits, a veteran must demonstrate a diagnosed condition supported by medical evidence that confirms the diagnosis. Additionally, credible supporting evidence must substantiate that an in-service stressor—typically related to the traumatic events experienced during military service—actually occurred. Furthermore, there must be a medical nexus, which means that medical evidence should link the current PTSD symptoms to the identified stressor.

Thus, the requirement for proof of combat engagement is not essential, as veterans who may have experienced trauma or stressors not directly linked to combat can still qualify for PTSD by meeting the other criteria, thereby allowing a broader range of veterans who may suffer from this condition to receive benefits and support.
