Refinement and Psychometric Properties of the Self-Efficacy for Sleep Hygiene Inventory

Area of Science:

• Sleep science
• Psychometrics
• Health psychology

Background:

• Sleep hygiene is crucial for young adults' well-being.
• Existing measures of sleep hygiene self-efficacy may require refinement for this demographic.
• Understanding self-efficacy is key to promoting healthy sleep behaviors.

Purpose of the Study:

• To identify core concepts of sleep hygiene self-efficacy in young adults and from sleep experts.
• To revise and psychometrically test the Self-Efficacy for Sleep Hygiene Inventory for young adults aged 18-26.

Main Methods:

• Qualitative input from young adult focus groups and sleep experts informed revisions.
• A revised inventory was administered to 296 young adults (ages 18-26) via electronic survey.
• Principal component analysis with Varimax rotation was used for factor analysis.

Main Results:

• A three-factor solution emerged: Behaviors to Adopt, Manage Mindset and Environment, and Behaviors to Avoid.
• Cronbach's alpha coefficients indicated good to excellent reliability for each subscale (.70–.85) and the total inventory (.88).
• The revised inventory demonstrated strong psychometric properties for measuring sleep hygiene self-efficacy in the target age group.

Conclusions:

• The revised Self-Efficacy for Sleep Hygiene Inventory is a reliable and valid measure for young adults.
• This instrument can aid in assessing and improving sleep hygiene self-efficacy in college students and young adults.
• Findings support the use of the inventory in research and clinical interventions promoting better sleep health.
