Evaluating the Sleep Hygiene Awareness and Practice Scale in Midlife Women With and Without Breast Cancer

Abstract

Background and Purpose: Sleep hygiene is one factor that contributes to poor sleep in breast cancer survivors but is poorly measured. The purposes of this study were to (a) evaluate the psychometric properties of the Sleep Hygiene Awareness and Practice Scale (SHAPS) and (b) compare SHAPS scores between midlife women with and without breast cancer. Methods: Cross-sectional, descriptive data from a single-blinded, controlled hot flash intervention trial. Results: 194 women (88 breast cancer survivors; 106 menopausal women). Reliability of the three sections of the SHAPS was inadequate with Cronbach’s alphas ranging from 0.23 to 0.67. Sleep hygiene practices were modestly correlated with global sleep quality in both groups. Conclusions: Findings suggest the SHAPS would need to be revised to be a psychometrically sound measure of sleep hygiene awareness and practice.
