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.
