What is the FAST used for?

The FAST measures how much difficulty a person has with everyday functioning, such as work, relationships, and managing money. Clinicians use it mainly in bipolar disorder to gauge real-world disability, track functional recovery over time, and see whether daily life is improving even when mood symptoms are under control.

How many items does the FAST have?

The FAST has 24 items spread across six domains: autonomy, occupational functioning, cognitive functioning, financial issues, interpersonal relationships, and leisure time. Each item is rated from 0 (no difficulty) to 3 (severe difficulty), producing a total score between 0 and 72, where higher scores indicate greater functional impairment.

What is a normal FAST score?

A total score of 11 or below is generally considered the non-impaired range, based on the cutoff that best separates patients from healthy controls. Scores of 12 to 20 suggest mild impairment, 21 to 40 moderate, and 41 to 72 severe. These bands guide clinical decision-making rather than confirm a diagnosis.

Who administers the FAST?

The FAST is usually completed by a trained clinician during a brief interview, taking around six minutes. Research also supports a self-administered version in outpatient settings. Either way, results should be interpreted alongside a full clinical picture, since functioning can be affected by many factors beyond a single condition.

Is the FAST free to use?

Yes. The FAST was published open access and its authors made it available for clinical practice and research use, so it can be built into digital intake without licensing fees. As always, confirm the current terms for your specific setting before wide deployment.

How often should the FAST be repeated?

Because the FAST tracks functional change rather than a fixed trait, many teams repeat it at intervals, for example at intake and then every few months. Comparing scores over time shows whether daily functioning is recovering, plateauing, or declining, which complements symptom-focused mood ratings.

The Functioning Assessment Short Test (FAST) is a 24-item, clinician-administered scale that measures difficulty in everyday functioning across six domains in people with bipolar disorder and other psychiatric conditions. It captures the real-world disability that symptom scales often miss, helping clinicians gauge functional impairment and track recovery over the course of treatment.

Why healthcare providers use the FAST

Captures real-world function. Symptom scores can improve while daily life stays impaired, and the FAST measures that gap directly.
Tracks recovery. Repeated scores show whether functioning is returning as treatment progresses.
Covers multiple life areas. Six domains span autonomy, work, cognition, finances, relationships, and leisure in one brief measure.
Quick to complete. A trained rater can finish the interview in about six minutes.
Validated and free. It has strong psychometric support in bipolar disorder and is available without licensing fees.

Which settings use the FAST?

Community mental health. Teams monitor functional recovery in people with bipolar disorder and related conditions.
Psychiatric outpatient clinics. Clinicians track how daily functioning changes between visits.
Early intervention services. It has been validated in first-episode psychosis to gauge functional impact.
Research and clinical trials. It serves as a functional outcome measure across mood and psychotic disorders.

What does the FAST measure?

The FAST rates the degree of difficulty a person experiences in everyday functioning over the recent past, rather than the presence of symptoms. A trained rater scores 24 items grouped into six domains, each capturing a distinct area of daily life.

Autonomy and daily living. Independence in self-care and managing routine activities.
Work and cognition. Occupational functioning alongside concentration, memory, and problem-solving.
Social, financial, and leisure life. Handling money, maintaining relationships, and taking part in free-time activities.

Scoring the FAST

Number of items: 24, across six domains.
Per-item scale: 0 to 3, where 0 is no difficulty and 3 is severe difficulty.
Total score range: 0 to 72.
Score direction: higher totals indicate greater functional impairment.

Scores summarize observed or reported difficulty and are meant to guide clinical decision-making, not to confirm a diagnosis on their own. Interpret results alongside history, symptom measures, and context, since functioning can be shaped by many factors beyond any single condition. The bands below reflect validated severity thresholds in bipolar disorder.

Score	Interpretation	Suggested next step
0-11	No functional impairment	Routine monitoring
12-20	Mild impairment	Watchful waiting
21-40	Moderate impairment	Consider further assessment
41-72	Severe impairment	Consider further assessment

Best practices for administration

Use a consistent time frame. Ask the patient to reflect on the same recent period each time so scores stay comparable.
Train raters. Consistent scoring across staff keeps repeat measures reliable.
Pair with symptom measures. Combine the FAST with mood ratings to separate functional recovery from symptom change.
Repeat on a schedule. Re-administer at set intervals to track trajectory rather than a single snapshot.
Review low-scoring domains. Look at which areas drive the total to focus follow-up discussion.

How Zentake helps with the FAST

Automatic scoring. Zentake totals the FAST on submit, so there is no hand-tallying of 24 items.
Longitudinal tracking. Re-send on a schedule and view how functioning changes over time.
Before the visit. Patients complete the FAST from home on any device, and mental health practices have results ready before the appointment.
HIPAA compliant. Every response is encrypted, with a signed BAA on every plan.

References

The FAST was developed and validated by Rosa and colleagues (2007) in Clinical Practice and Epidemiology in Mental Health, establishing its 24-item structure, six domains, and a cutoff above 11 for distinguishing functional impairment.

Severity thresholds (no impairment 0 to 11, mild 12 to 20, moderate 21 to 40, and severe 41 to 72) were derived by Bonnin and colleagues (2018) in the Journal of Affective Disorders. A self-administered version has since been evaluated for outpatient mental health settings.
