The purpose of this study is to understand whether Black participants with insomnia with objective short-sleep (ISSD) experience less symptom improvement in response to Cognitive Behavioral Therapy for Insomnia (CBTi) than Insomnia with Normal Sleep Duration (INSD) and whether this difference is driven by downstream racism-related stress and experiences. The investigators propose an innovative pragmatic open-label design in which Black participants with insomnia undergo a standard 6-week protocol of digital CBTi. The investigators will quantify ISSD using wireless EEG and will gather high-resolution naturalistic data of racism-related stress using random smartphone prompts and Ecological Momentary Assessments (EMA).
