REFRESH Study

This study has two parts.

In Part 1, 15 gynecologic cancer survivors will receive three candidate intervention components known to reduce sleep disturbance (i.e., sleep restriction, stimulus control, systematic light exposure) simultaneously for six weeks. Participants will then complete semi-structured individual interviews to provide feedback about barriers to and facilitators of intervention adherence. Results of Part 1 will inform the design and delivery of the candidate components in Part 2.

In Part 2, a 2^3 full factorial design will be followed to randomize 80 gynecologic cancer survivors to one of eight six-week intervention conditions reflecting all possible combinations of the three candidate intervention components.
