Sleep and thinking improvement app for breast cancer survivors

This trial is testing whether a smartphone app called Hvil® that teaches cognitive behavioral therapy for insomnia (a proven talk-based approach) can help breast cancer survivors who have finished treatment and are struggling with sleep problems and trouble concentrating or remembering things. The study will compare this app-based sleep therapy to a simpler app that just teaches basic sleep habits. Researchers will look at whether the more intensive therapy helps people sleep better and think more clearly.

Many breast cancer survivors experience ongoing problems with sleep and concentration even after their cancer treatment ends, and these problems can significantly affect their quality of life. This trial exists to see if a convenient app-based therapy—which works well for insomnia in other groups—can help these survivors regain better sleep and clearer thinking.
