What you are being asked for
A patient asks you to "fill out a form for my VA claim." Three quite different requests hide inside that sentence, and they are worth separating before you start.
- Document the condition. A Disability Benefits Questionnaire organizes diagnosis, history, testing, treatment, symptoms, and functional effect into the structure the adjudicator reads.
- Explain a connection. Whether a condition was caused or worsened by service, or by another service-connected condition, is a separate question. It usually needs reasoning, not a checkbox.
- Decide entitlement. That is not yours. The Veterans Benefits Administration makes the legal decision, and nothing you write obliges them.

"At least as likely as not" is a legal standard, not a clinical one
This phrase appears throughout VA medicine and it causes real confusion. It is a standard of proof, roughly a 50 percent threshold in an adjudicative system that resolves approximate balance in the veteran's favor. It is not a request that you express clinical confidence you do not have, and it is not equivalent to a p-value, a likelihood ratio, or anything else from your training.
You are being asked whether the evidence supports the connection at least as much as it opposes it. If it does not, say so. If you cannot tell, say that, and say why — "the records needed to answer this are not available to me" is a useful, truthful answer that an adjudicator can act on.
Causation and aggravation are two questions
A service-connected condition may have caused another condition, or it may have made an existing one worse. These are independent, and an opinion that answers only the first leaves the second open.
"Condition A did not cause condition B" does not answer whether A aggravated B. Opinions that stop there are a recurring reason claims come back for further development, which costs the veteran months. If you address one, address both, or state plainly which one you are addressing.
Writing something useful
Identify what you examined and what records you reviewed. Separate what you observed from what the patient reported. Where the form asks about function, describe it concretely — what the person can no longer do, how often, and for how long. Where a question is outside your expertise, say so rather than estimating.
Use your own judgment. A request is not a brief, and a patient hoping for a particular conclusion does not change what the record supports.
If you work at VA
VHA Directive 1134(3) is the national policy on completing forms and providing medical statements for patients. It addresses DBQs specifically, including when completion can happen during a visit. It also recommends that treating clinicians generally not complete mental-health DBQs, to protect the treatment relationship — a recommendation about one category, not a bar on helping at all.
Written for clinicians. This describes what VA asks for and what the adjudicator does with it. It is not clinical guidance and does not tell you what to conclude. Phrases such as “at least as likely as not” are legal standards of proof, not statements of clinical confidence.
