What Not to Say on a Disability Function Report (And Why It Matters)

The Adult Function Report (Form SSA-787) is one of the most consequential documents in an SSDI application — and one of the most misunderstood. Many claimants don't realize that what they don't say, or what they say carelessly, can be just as damaging as missing medical records. Social Security uses this form to understand how your condition affects your daily life, and reviewers are trained to spot inconsistencies.

Here's what typically hurts claimants — and why.

What the Function Report Actually Does

The Function Report asks about your daily activities: cooking, cleaning, driving, shopping, socializing, concentrating, following instructions. It's not a symptom checklist. It's a functional snapshot — how your condition limits what you can do, not just what you have.

The Disability Determination Services (DDS) reviewer uses your answers alongside medical records to build a picture of your Residual Functional Capacity (RFC) — essentially, what work you can still perform. If your answers suggest more capability than your medical evidence supports, that contradiction becomes a problem.

Common Mistakes That Undermine a Claim

1. Overstating What You Can Do to Appear "Normal"

Many claimants instinctively minimize their limitations. They say they cook meals when the reality is they occasionally microwave soup. They say they do housework when they mean they sometimes load the dishwasher on good days.

Don't describe your best day. Describe your typical day — including bad days, how often they occur, and what you can't finish even when you start.

Saying "I cook for my family" when you actually can't stand long enough to use the stove without pain is the kind of inconsistency that reviewers flag.

2. Giving Vague, Unqualified Answers

Answering "sometimes" or "a little" without context gives reviewers room to interpret your limitations generously — in their favor, not yours.

Instead of: "I have trouble sleeping." Try: "I sleep 2–3 hours at a time due to pain and wake up 4–5 times a night."

Specificity protects you. Quantify where you can — distances walked, minutes stood, times per week, how long tasks take compared to before your condition.

3. Listing Activities Without Explaining the Cost

You can walk to the mailbox. You can drive short distances. You can attend a family event once a month. None of that automatically means you can work — but if you list those activities without explaining the limitations and aftermath, reviewers may treat them as evidence of functional capacity.

Always note:

• How long it takes
• Whether you need help or rest breaks
• What symptoms result (pain flare, fatigue, confusion)
• Whether you can do it consistently, day after day 🗓️

The SSA is specifically interested in whether you can perform work on a sustained, full-time basis — not whether you can occasionally do something on a good day.

4. Contradicting Your Medical Records

If your doctor's notes say you can't lift more than 10 pounds and you write on the function report that you carry groceries, that's a red flag. DDS reviewers compare your self-reported activities against your treatment records.

Before completing the form, review your recent medical documentation. Your answers should align with — not contradict — what your providers have observed and recorded.

5. Leaving Sections Blank or Writing "N/A"

Blank answers can suggest you have no limitations in that area. If a question doesn't apply because your condition prevents you from doing the activity at all, say that explicitly. "I cannot do this due to [symptom/condition]" is far more useful than leaving the field empty.

6. Focusing Only on Physical Limitations (or Only Mental Ones)

SSDI evaluates the combined effect of all your impairments. If you have both a physical condition and depression, anxiety, or cognitive difficulties, both need to be reflected in the function report. Many claimants skip the questions about memory, concentration, getting along with others, or handling stress — either because they feel embarrassed or because they think only physical symptoms "count."

They count. The RFC assessment includes mental and cognitive limitations, and leaving them undocumented means they won't factor into the decision the way they should. 🧠

The Factors That Shape How This Form Is Weighted

No two function reports are reviewed in exactly the same context. How much weight yours carries depends on:

What This Means Across Different Claimant Profiles

A claimant with well-documented medical records and a straightforward physical condition may find the function report serves mainly as corroboration. A claimant with a mental health condition, a fluctuating illness like lupus or MS, or limited medical records may find the function report carries significantly more weight — because it's filling in gaps that objective tests can't fully capture.

At the ALJ hearing stage, inconsistencies between your function report and your testimony can become direct lines of questioning. A judge who sees "drives independently" checked on a form and then hears testimony about severe anxiety in traffic will want an explanation.

The function report isn't just paperwork — it's part of your evidentiary record. How it interacts with your specific medical history, work background, and the stage of your claim is what ultimately determines how much it helps or hurts your case.
