Background And Purpose:
Few studies have examined how self-efficacy is related to sleep behaviors in young adults. The purpose of this study was to develop and test an instrument specifically designed to measure self-efficacy for sleep hygiene in young adults.
Methods:
The Self-Efficacy for Sleep Hygiene Inventory (SESHI) was developed in three phases using principal components analysis. The 30-item scale was pilot tested with a sample of 305 young adults. A second study with a sample of 96 young adults confirmed reliability.
Results:
A 24-item three-factor solution: time management, disruptive influences, and sleep influences. Cronbach's alphas were 0.83 (total SESHI), 0.87 (time management), 0.69 (disruptive influences), and 0.73 (sleep influences).
Conclusions:
Initial psychometric testing indicated the SESHI may be a reliable measure of self-efficacy for sleep hygiene in this population.
