Adherence
Individuals with high scores on the Ford Insomnia Response to Stress Test (FIRST) exhibit significantly lower sleep efficiency and increased sleep latency during a first night in the laboratory compared to those with low scores, indicating a trait vulnerability to stress-related sleep disturbance.
If you find that stressful events consistently ruin your sleep, you may have a physiological trait called 'stress-related vulnerability.' This isn't a character flaw; it's a predisposition. Understanding this can help you manage expectations and seek targeted interventions (like stress management techniques) rather than just blaming yourself for poor sleep hygiene.
Individuals with higher scores on this scale, the Ford Insomnia Response to Stress Test (FIRST; median split), had a lower sleep efficiency (P = .001), as well as an increased latency to stage 1 sleep (P = .001) and persistent sleep (P = .002) on the first night of nocturnal polysomnography.
Why this rating
Randomized population-based sample with polysomnographic verification, though it is a cross-sectional observation of a 'first night' effect rather than a long-term intervention.
