Sleep issues and their relationship to health and operational effectiveness problems are a growing concern for those serving in the military. In this small study, all 23 members of a U.S. Army Selected Reserve medical unit participated over one month in an online sleep hygiene intervention. Participant sleep quality and sleep duration before and after the intervention were measured using a pre-post assessment design utilizing the Pittsburgh Sleep Quality Index (PSQI). Although no change in pre-post total PSQI scores was found, there was a statistically significant (p < .05) increase in participants’ self-reported number of hours slept per night. This change over time suggests the online sleep hygiene intervention may affect number of hours slept per night over a monthlong period.
