How to Write SF 3112A for Mental Health: Applicant Statement That OPM Takes Seriously

What SF 3112A Is Actually Asking You to Do

Form SF 3112A — the Applicant's Statement of Disability — is your personal narrative explaining how your medical condition prevents you from performing the duties of your federal position. For psychiatric conditions, this form is where most applications either succeed or fail. OPM adjudicators read thousands of these, and the ones that get approved share a common structure: they connect specific clinical symptoms to specific job duties with enough detail that the reviewer can follow the causal chain from diagnosis to positional deficiency.

The form asks you to describe your disease or injury and how it interferes with your duties, attendance, or conduct. SF 3112C provides the physician's clinical evidence, including diagnosis, findings, and treatment history. And it's absolutely not asking you to vent about your supervisor, your agency's culture, or your workplace stress. OPM routinely denies claims that read as complaints about a difficult work environment rather than documentation of a disabling medical condition.

The Structure That Works

A well-organized SF 3112A for a psychiatric condition follows this progression:

Section 1: Identify your condition and connect it to your position. State your DSM-5 diagnosis (your physician will have given you the formal name), when you were diagnosed, and the position you hold. Reference your position description by title, series, and grade.

Section 2: Map symptoms to duties. This is the core of the statement. Take each major symptom of your condition and connect it to a specific duty or critical element from your position description.

For depression: "Major Depressive Disorder causes severe executive dysfunction and psychomotor slowing. My position as a GS-12 Management and Program Analyst requires synthesizing regulatory data from multiple sources into analytical reports within 5-business-day turnarounds. Since approximately [date], I have been unable to sustain the cognitive focus required to complete these analyses within assigned timeframes."

For PTSD: "Post-Traumatic Stress Disorder causes hypervigilance, intrusive flashbacks, and severe startle response. My position as a GS-9 Veterans Service Representative requires continuous face-to-face interviews with claimants in an open-plan office. Intrusive flashbacks during interviews have caused me to lose my train of thought mid-sentence, and panic episodes have required me to leave the interview room on [number] occasions in the past [timeframe]."

For anxiety: "Generalized Anxiety Disorder causes persistent cognitive flooding and decision paralysis. My position as a GS-11 Contract Specialist requires independent acquisition decisions under FAR deadlines. Anxiety-driven indecision has caused me to miss [number] procurement deadlines in [timeframe], resulting in [documented consequence]."

Section 3: Document accommodation failure. Explain what accommodations were requested, whether they were granted, and why they didn't restore your ability to perform useful and efficient service. If accommodations were denied, state that.

Section 4: Describe the attendance and performance impact. Reference your leave usage — sick leave exhaustion, FMLA usage, LWOP periods — and any documented performance issues. Use dates and numbers, not generalizations.

Three Mistakes That Sink Mental Health 3112A Statements

Mistake 1: Writing about workplace conflict instead of medical impairment. If your statement reads like "My supervisor bullies me and causes my anxiety," OPM will treat it as a personnel dispute, not a disability claim. Even if your supervisor genuinely worsened your condition, the statement must focus on the medical condition itself and how it impairs job functions regardless of who your supervisor is. The condition must persist across work environments — if removing one supervisor would solve the problem, OPM will conclude you don't need disability retirement.

Mistake 2: Being vague about duties. "I can no longer handle the stress of my job" tells OPM nothing. They need to know which specific duties in your position description you can no longer perform, and exactly how your symptoms prevent those specific tasks. Pull your PD from your HR file and reference it by line item.

Mistake 3: Overstating the case. Claiming you "cannot do anything" or are "completely non-functional" invites skepticism, especially if your leave records show you worked intermittently during the period you describe. Be precise about what you can and cannot do. OPM is more persuaded by a detailed account of specific incapacities than by a blanket declaration of total disability.

Aligning 3112A with Your Other Forms

Your SF 3112A doesn't exist in isolation. OPM reads it alongside the SF 3112B (supervisor's statement), SF 3112C (physician's statement), and SF 3112D (agency certification). Contradictions between these forms are the fastest route to denial.

Before you finalize your 3112A, make sure:

• The symptoms you describe match your physician's diagnosis and clinical notes on SF 3112C
• The duty impairments you cite are consistent with the performance issues your supervisor documents on SF 3112B
• The accommodation failures you reference match what the agency certifies on SF 3112D
• The dates in your narrative align with dates in your medical records and leave history

If your supervisor's statement contradicts your account — minimizing your symptoms or attributing your performance problems to attitude rather than illness — your SF 3112A and 3112C need to be strong enough to carry the application independently. Official leave records and performance documentation can corroborate your account regardless of what your supervisor writes.

Keeping It Focused

OPM adjudicators review a high volume of applications. A 3112A that rambles for 15 pages about your childhood, your work history, and your feelings about the federal government will not be read carefully. The strongest statements are 3 to 5 pages, tightly organized, and relentlessly specific about the connection between medical symptoms and position duties.

Every paragraph should answer one question: "How does this clinical symptom prevent this job duty?" If a paragraph doesn't answer that question, delete it.
