The goal of the study is to investigate whether a brief behavioral therapy for insomnia (BBTI) improves sleep in bereaved patients screened for insomnia compared to an active control group (sleep hygiene education). The study will also explore if BBTI improves symptoms of complicated grief. The investigators will recruit approximately 58 bereaved participants with insomnia.
