Structured Functional Surveys for SSD Cases: A Rolling, Mini SSA-3373

The Function Report asks the right questions. It asks them once, months late, from memory. A rolling daily survey asks the same questions every day, in real time, and builds the longitudinal record your claimant's hearing demands.

The SSA-3373 (Function Report — Adult) is Social Security's standard instrument for assessing a claimant's self-reported daily functioning. It covers personal care, meal preparation, house and yard work, shopping, social activities, hobbies, concentration, following instructions, and physical capacities.

As a one-time form, the SSA-3373 has the right scope but the wrong methodology. It captures a retrospective snapshot of the claimant's recollection at a single point in time. It does not capture the pattern of function across days, weeks, and months. It does not enforce contemporaneity. It does not produce quantified data. It does not build the longitudinal evidence an ALJ needs for an RFC determination.

The rolling, mini SSA-3373 approach takes the functional dimensions the SSA-3373 evaluates and captures them daily through structured surveys the claimant completes in 3–5 minutes on a mobile device. Instead of one retrospective form, the result is hundreds of contemporaneous data points that answer every SSA-3373 question with documented, quantified evidence.

Effective functional surveys for SSD cases are not generic health questionnaires. They are purpose-built instruments that map directly to the RFC categories ALJs must evaluate.

Physical Exertion Block

Captures the exertional dimensions that determine whether the claimant can perform sedentary, light, medium, or heavy work:

• Sitting tolerance (duration before needing to change position)
• Standing tolerance (duration before needing to sit or lie down)
• Walking capacity (distance/duration before resting)
• Position changes required throughout the day
• Lifting and carrying activities completed or attempted

Each daily response contributes to a longitudinal dataset showing actual physical capacity over time, with averages, ranges, and trends.

Rest and Reclining Block

Captures the two RFC dimensions most likely to determine vocational outcomes:

• Hours spent resting or reclining beyond normal sleep
• Number of unplanned rest breaks
• Duration of rest breaks
• Whether rest was needed to continue daily activities

This block generates the rest/reclining calendar exhibits that document one of the most common bases for finding a claimant unable to sustain competitive employment.

Cognitive Function Block

Captures mental RFC dimensions:

• Ability to sustain focused activity (reading, watching, task completion)
• Number of symptom-related interruptions to focused activity
• Approximate time lost to off-task episodes
• Tasks started but not completed due to cognitive or symptom interference

This block generates the off-task percentage data that maps directly to vocational expert threshold testimony (>15–20% off-task = no competitive employment).

Activities of Daily Living Block

Captures the functional dimensions the SSA-3373 evaluates:

• Meal preparation (independent, with assistance, unable)
• Personal care (bathing, dressing, grooming — independent or required help)
• Household maintenance (cleaning, laundry, dishes)
• Left the house today (yes/no, for what purpose)
• Errands or shopping attempted
• Social interaction outside the household

This block produces the evidence-based equivalent of a Function Report — except instead of one retrospective form, it is built from daily documented data across the entire documentation period.

Medication and Treatment Block

Captures treatment-related dimensions:

• Medication side effects experienced today (drowsiness, nausea, dizziness, cognitive dulling)
• Whether side effects interfered with daily activities
• Appointments attended or missed
• Treatment compliance notes

This block generates medication side-effect frequency data and feeds the treatment compliance tracking that protects against SSR 18-3p issues.

Symptom Variability Block

• Overall day rating (better than usual / about average / worse than usual)
• Flare-up occurrence and approximate duration
• Primary symptoms experienced today

This block captures the good-day/bad-day pattern that is critical for understanding functional variability and projecting absenteeism.

Not all client documentation is created equal. Three common approaches produce very different evidentiary quality:

The optimal approach combines structured surveys (for quantified, RFC-mapped data) with multimedia journal entries (for the specific, vivid incidents that give ALJs a window into daily reality). The structured data provides the statistical foundation; the journal entries provide the human texture.

The evidentiary value of daily surveys depends on contemporaneity — the assurance that each entry reflects the day it describes, not a later reconstruction. A Client Evidence Engine enforces this by design: claimants can only submit survey responses for the current day. There is no mechanism to go back and fill in prior days.

This design choice has direct evidentiary consequences:

• The timestamp on each entry is system-generated, not claimant-reported
• The record is resistant to the objection that entries were fabricated or embellished after the fact
• Missing days are visible in the record — they are gaps, not opportunities for retroactive data entry
• The resulting record has the evidentiary quality of a contemporaneous diary, with the additional advantage of structured, quantified data

For the full treatment of why contemporaneity matters in ALJ credibility determinations, see Contemporaneous vs. Reconstructed Functional Evidence.

Hundreds of daily survey responses do not go to hearing as raw data. The evidence pipeline transforms daily inputs into the outputs representatives use:

Averages and ranges: "Over 285 documented days, the claimant's average daily resting/reclining time was 2.3 hours (range: 0.5–4.5 hours)."

Percentages: "The claimant was unable to prepare a meal independently on 47% of documented days."

Trends: Charts showing how function has changed across the documentation period — stable impairment, gradual decline, or variable patterns.

RFC-mapped summaries: Functional data organized by RFC category, ready for exhibit submission and vocational expert hypothetical questions.

These outputs transform the SSA-3373's retrospective guesswork into quantified, longitudinal evidence. For the exhibit-preparation methodology, see SSD Hearing Exhibits: Turning Functional Data Into Evidence ALJs Can Rely On.
