Abstract:
Objective
& Design: Sleep problems are common and have been linked to health
problems, diminished well-being, and impaired performance. Many scales
to diagnose clinically relevant sleep problems are time-consuming,
complex, and difficult to administer in non-clinical and multi-thematic
studies. Through a multi-stage translation (from English to German) and
scale testing process, we developed a parsimonious measure of sleep
problems and daytime functioning for non-clinical applications based on
the Athens Insomnia Scale. Results: Exploratory (NStudy 1 = 25,140) and confirmatory (NStudy 2
= 14,797) factor analyses suggest a two-dimensional structure with the
subscales “sleep problems” and “daytime functioning”. Internal scale
consistency was acceptable. Measurement invariance was found across
time, gender, age, and diagnosed sleep disorders. The scale
discriminates between people with and without sleep disorders and
predicts emerging sleep disorders. Short-term retest reliability was
acceptable (NStudy 3 = 78). Convergent validity with other sleep measures and discriminant validity with indicators of well-being were observed (NStudy 4
= 341). After a multi-stage translation to English, we confirmed the
factor structure and found measurement invariance across languages (NStudy 5
= 623). Conclusion: Our short 7-item scale has good psychometric
properties and is suitable for self-administration, making it useful in
measuring sleep problems and daytime functioning efficiently and
reliably, especially for large population studies.
