What is the research assumption?
a. This study was undertaken to explore the effect of massage on total hours of sleep per 24-hour day, in persons averaging fewer than 7 hours of sleep per night, attributable to insomnia.
b. It was posited that provision of daily late-morning massage would affect total hours of sleep per 24-hour day.
c. It was taken as established fact that massage is pleasant, that research subjects getting fewer than 7 hours of sleep per night were sleep-deprived, and that endorphins mediated the changes observed.
d. Presumably by increasing endorphin levels, massage seems to provide an immediate relaxation and an ability to sleep immediately following the session, but it is unclear whether these benefits actually extend to total sleep, despite anecdotal support. The claim that massage increases total hours of sleep has been inadequately researched.

Assumptions are statements that are taken for granted or that are considered true, even though they have not been scientifically tested. Assumptions are often embedded (unrecognized) in thinking and behavior, and uncovering them requires introspection. Sources of assumptions include universally accepted truths, theories, previous research, and nursing practice.
