SSDI Adult Function Report Guide: Quick Steps for SSA‑3373

Struggling to fill out the SSDI Adult Function Report (SSA‑3373)? You’re not alone—this form decides whether your disability claim gets approved, and vague answers lead to denials. Below is a plain‑English, step‑by‑step walkthrough that shows exactly what reviewers want and how to give it to them.

Why Details Matter on the SSA‑3373 Form

The Social Security Administration needs concrete proof of how your condition limits everyday life. When I first left many activity boxes blank, my claim was denied because the reviewer saw insufficient evidence of functional limitations. Specific time frames, body parts, and triggers turn a generic answer into a convincing case.

Use the Three‑Chunk Method to Describe Your Day

Break your typical day into morning, afternoon, and evening blocks. Write one short sentence for each block that includes what you do, how long it takes, and why your condition makes it hard.

Example for morning: “I need about 45 minutes to get out of bed, find my clothes, and put on shoes because my back pain makes bending painful.”
Example for afternoon: “I avoid grocery shopping because crowds trigger panic attacks that last 20–30 minutes, so I rely on a friend for food deliveries.”
Example for evening: “During the afternoon I often experience a ‘brain fog’ that makes it impossible to focus on paperwork for more than ten minutes, so I take frequent breaks.”

If you’re stuck, ask: What does a bad‑symptom day look like for me? Jot a quick bullet list before you start typing; it keeps answers consistent and prevents second‑guessing.

Section‑by‑Section Guide to Completing SSA‑3373

Personal Information

Enter your name, SSN, and contact info exactly as they appear on other paperwork. Double‑check spelling; a typo can delay processing.

Work History

List the most recent job you held, even if you haven’t worked in a while. Include job title, employer, and dates. If you left because of your condition, add a short note such as “Stopped working March 2022 due to worsening depression and chronic pain.”

Daily Living Activities

This is the core of the form. Use the three‑chunk method for each category: Personal Care, Household Tasks, Social Interaction.

• Personal Care – “Morning: Takes 20 minutes to brush teeth and wash face because hand tremors make gripping the toothbrush difficult.”
• Household Tasks – “Afternoon: Can’t vacuum for more than 5 minutes at a time; back pain forces me to rest after each room.”
• Social Interaction – “Evening: Avoids phone calls after 6 pm because anxiety spikes, leading to sleeplessness.”

Each bullet must contain a time frame and a why (the symptom that limits you). This satisfies the reviewer’s need for examples without sounding templated.

Medical Information

Copy the list of doctors, therapists, and medications from your latest medical summary. Be explicit: “Diagnosed with Major Depressive Disorder, receiving weekly CBT and 50 mg of sertraline.” Showing active management strengthens your claim.

Symptoms and Limitations

Reinforce the details you gave earlier with short, punchy sentences.

• “Severe fatigue after 30 minutes of standing.”
• “Memory lapses make it hard to follow multi‑step instructions.”
• “Nightly panic attacks lasting 15 minutes disrupt sleep.”

Be honest about mood swings, concentration issues, and medication side effects—including drowsiness.

Signature and Date

Sign and date the form. If filling it out electronically, type your name in the signature field. Keep a copy for your records.

Pro tip: I created a printable checklist that walks you through each step. Grab it from the SSDI Made Easy resources page and print it out before you start. Having the checklist on hand prevents missed sections and makes the process feel less overwhelming.
