Objective:
Sleep health is a multifaceted concept encompassing six core dimensions: satisfaction, alertness, timing, regularity, efficiency, and duration. Individual and age-related differences in sleep health are associated with both mental and physical health. Comprehensive measures are needed to evaluate these differences and tailor treatment and preventive approaches.
Methods:
The present study developed and validated the Sleep Health Dimensions Questionnaire (SHDQ), a multidimensional measure of sleep health inadults. 1273 college students filled out the SHDQ and measures of insomnia, depression, anxiety, emotion regulation, and health-related quality of life. We evaluated the reliability, validity and factor structure of the questionnaire.
Results:
The SHDQ demonstrated strong psychometric properties, including internal consistency (Cronbach's α = 0.80), item-to-total correlations (r > 0.30), and convergent and divergent validity. The SHDQ effectively discriminated clinically relevant insomnia cases. The SEM model showed a good fit, indicating that the dimensions of sleep health are effective indicators of a main latent variable (multi-dimensional sleep health).
Conclusions:
The SHDQ comprehensively evaluates sleep health dimensions. As a research tool, it is useful for exploring the relationship between sleep health and mental and physical health across various adult populations.
