Ford Insomnia Response to Stress Test
Also known as: FIRST, Ford Insomnia Response to Stress Test
The Ford Insomnia Response to Stress Test (FIRST) is a brief self-report measure designed to identify individuals with heightened vulnerability to insomnia in response to psychological stress. Developed by Ford and Kamerow in 1990, it captures the tendency to experience sleep disruption during periods of worry, work pressure, or major life events. The FIRST is useful in identifying which individuals are at risk for insomnia during transitions or stressful periods, and in understanding individual differences in stress-related sleep reactivity.

When to use it
The FIRST is indicated when assessing insomnia risk in individuals facing anticipated stressors (career transitions, major life changes, medical conditions), monitoring individuals with history of stress-induced insomnia, identifying those who may benefit from preventive behavioral intervention, and in research examining the role of stress reactivity in insomnia etiology. Also useful in stress-related disorders (adjustment disorders, anxiety disorders) to characterize sleep vulnerability. Not intended as a diagnostic instrument for insomnia disorder; rather, it identifies trait vulnerability to stress-induced sleep disruption.
Strengths & limitations
- Captures trait-like individual differences in stress sensitivity relevant to sleep; useful for identifying at-risk populations
- Brief, simple administration requiring minimal time and cognitive demand; easily administered in routine clinical care
- Grounded in stress-diathesis model of insomnia; theoretically sound approach to understanding individual vulnerability
- Useful for prevention and early intervention targeting; identifies individuals who may benefit from stress management or preemptive CBT-I
- Free to use; no licensing required
- Limited psychometric documentation; fewer validation studies compared to established insomnia severity scales (ISI, SCI)
- Does not directly measure insomnia severity or symptom presence; captures vulnerability only, not actual sleep disturbance
- Relies on retrospective recall of sleep response to past stressors; subject to recall bias and interpretation of what constitutes 'stress'
- Does not differentiate primary insomnia from stress-reactive sleep disruption; stress response varies with underlying sleep disorders
- May not be validated across all populations; generalization to non-Western cultures or diverse stress contexts uncertain
Frequently asked
What is the difference between the FIRST and insomnia severity scales like the ISI or SCI?
The FIRST measures trait vulnerability to stress-induced insomnia (would you develop insomnia during stress?), while severity scales measure current insomnia symptoms and impact. You can score low on FIRST (resilient to stress) but high on ISI/SCI (currently experiencing insomnia), or vice versa. Different constructs, different clinical uses.
If I score high on the FIRST, does that mean I have insomnia disorder?
No. High FIRST score indicates you are vulnerable to sleep disruption during stress, but does not diagnose current insomnia. You may sleep well currently. Insomnia diagnosis requires sleep difficulty symptoms plus daytime impairment persisting ≥3 nights/week for ≥3 months.
Can the FIRST predict whether I'll develop insomnia during an upcoming stressful event?
High FIRST scores indicate elevated risk, but prediction is not certain. Many high-reactivity individuals maintain good sleep through stress management, exercise, social support, and coping skills. Low FIRST scores do not guarantee sleep will be unaffected by extreme stress.
How should I use FIRST results to guide treatment?
High FIRST indicates preventive intervention may be valuable: stress management training, cognitive-behavioral therapy for insomnia (CBT-I), exercise, mindfulness, sleep hygiene reinforcement. Treat underlying stress (work demands, relationship issues) in parallel. Monitor for insomnia symptoms during stressful periods.
