The Adult Function Report (Form SSA-787) is one of the most important documents in your SSDI application — and one of the most misunderstood. Many claimants treat it as a formality. SSA reviewers treat it as evidence. What you write, how you write it, and what you leave out can all shape how a disability examiner at the Disability Determination Services (DDS) understands your functional limits.
This guide walks through what the form is asking, what strong answers look like, and why generic or overly brief responses tend to work against claimants.
SSA isn't only asking whether you have a medical condition. They're asking how that condition affects what you can do on a daily basis. This connects directly to your Residual Functional Capacity (RFC) — SSA's assessment of the most you can still do despite your impairments.
The form covers eight broad areas of daily functioning:
Each section is asking: Can you sustain these activities? At what cost? With what limitations?
A claimant with chronic pain might write: "I can cook meals." That sounds functional. But the fuller picture might be: "I can heat soup or make a sandwich, but standing at the stove for more than 10 minutes causes severe lower back pain. I have to sit or lie down afterward for 30–60 minutes."
The second answer tells DDS something the first one doesn't — that even basic tasks come with a recovery cost. SSA is specifically interested in pace, persistence, and the ability to sustain activity over a full workday. A task you can do once, slowly, with significant pain or fatigue afterward is functionally different from a task you can perform consistently.
Weak answer: "I shower and get dressed daily."
Stronger answer: "I shower every 2–3 days because standing in the shower causes dizziness and exhaustion. I sit on a shower bench. Getting dressed takes 20–30 minutes because bending and lifting my arms causes pain. My spouse helps with buttons and shoes."
The stronger answer reflects the how, the frequency, and any adaptive strategies or assistance involved.
Weak answer: "I make simple meals."
Stronger answer: "I can microwave food or pour cereal. I cannot stand at the stove for more than 5 minutes without needing to sit. I stopped cooking regular meals about eight months ago because of [condition]. My son cooks most dinners."
Weak answer: "I have trouble focusing sometimes."
Stronger answer: "I can watch TV for about 20 minutes before I lose track of the plot. I forget appointments and have to set multiple phone alarms. I often read the same paragraph several times and still don't retain it. I stopped driving because I got confused on familiar routes twice."
Cognitive limitations are especially important to document specifically because they're invisible and often underdescribed.
You don't need to exaggerate. You need to be specific and honest. Vague answers like "I can't do much" give reviewers nothing concrete to evaluate. SSA examiners are comparing your reported limitations against your medical records. When your function report aligns with your treatment notes — or explains gaps in treatment — it strengthens your case. When it contradicts your records or claims total inability in areas your doctor hasn't documented, it raises credibility questions.
Not all function reports are evaluated the same way. Several factors shape how much weight your answers carry:
| Factor | Why It Matters |
|---|---|
| Medical condition type | Physical vs. mental impairments affect which functional areas are most scrutinized |
| Application stage | Initial review vs. ALJ hearing — judges may weigh testimony differently than DDS examiners |
| Consistency with medical records | Reports that match documented symptoms carry more credibility |
| Third-party function report | A completed form from a family member or caregiver can corroborate your account |
| Date limitations began | Ties to your alleged onset date and how long limitations have persisted |
SSA also offers a Third-Party Adult Function Report, which a spouse, caregiver, or close friend completes independently. This isn't a duplicate — it's a corroborating perspective. When a third party's observations match what you've reported, it adds weight. When they've witnessed specific incidents (falls, confusion, inability to complete tasks), those observations become part of the evidentiary record.
The examples above illustrate the direction of a strong answer — specific, functional, honest about frequency and cost. But the right level of detail, which limitations to emphasize, and how those answers connect to your specific medical evidence depend entirely on your diagnosis, your treatment history, and what your records already show.
A claimant with degenerative disc disease will fill this out differently than someone with bipolar disorder, diabetic neuropathy, or PTSD. The form is the same. The strategy — what to focus on, what to explain more carefully — isn't.
Your function report is a piece of a larger file. How well it fits with everything else in that file is something only someone who knows your full medical picture can assess.
