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

Abstract

The purpose of this study was to determine key concepts of self-efficacy for sleep hygiene among young adults/college students and sleep experts, and to refine the Self-Efficacy for Sleep Hygiene Inventory. The Self-Efficacy for Sleep Hygiene Inventory was revised using input from young adult focus groups and experts. Information from focus groups informed instrument revision. The revised instrument was distributed using an electronic survey to young adults age 18–26 years for a total sample of 296. A principal component analysis with Varimax Orthogonal Rotation was conducted resulting in a three-factor solution. Cronbach’s alphas were: .85 for Behaviors to Adopt (nine items), .79 for Manage Mindset and Environment (eight items), .70 for Behaviors to Avoid (eight items), and .88 for the inventory (twenty-five items). Initial psychometric testing of the Self-Efficacy for Sleep Hygiene Inventory-Revised indicates that it is a reliable measure of self-efficacy for sleep hygiene in young adults age 18–26 years.

Examining the Direction of Effects Between COVID-19 Experiences, General Well-Being, Social Media Engagement, and Insomnia Symptoms Among University Students

“…Emerging adults who were better psychologically adjusted at baseline reported improved sleep quality 5 months later during the pandemic. Self-efficacy might be one mediating factor in the link between well-being and insomnia symptoms (Gipson et al, 2020). Another possibility is that higher well-being might promote psychological resources such as grit and resilience that facilitate effective coping during the pandemic (Paredes et al, 2021), which may, in turn, reduce insomnia symptoms.…”
