Purpose

PRIMARY OBJECTIVE(S): To evaluate the efficacy of the Brief Behavioral Therapy for Insomnia (BBT-I) in treating insomnia among breast cancer patients receiving chemotherapy. SECONDARY OBJECTIVE(S): * To evaluate the efficacy of the BBT-I in treating cancer-related symptoms such as cancer-related fatigue and cognitive difficulties in breast cancer patients receiving chemotherapy. * To examine potential moderators and mediators of BBT-I intervention effects on insomnia, cognitive difficulties, and fatigue. In particular, we are interested in age, depression and anxiety and side effects (hot flashes) as potential moderators of the intervention effects as well as evaluating modifiable behavioral and physiological mechanisms as hypothesized mediators
