 This project will assess the acute and long-term effectiveness of dCBT-I on Research Domain Criteria RDoC sleep parameters: Insomnia Severity Index ISI, sleep onset latency, and wake after sleep onset in an insomnia cohort including those at elevated risk for depression e.g. high sleep reactivity, low SES, minority. This will be tested by administering internet-based dCBT-I to people with insomnia and adding face-to-face CBT-I in non-remitters ISI 10, as well aS comparing the RDoC sleep outcomes to an attention control group post-treatment and at 1 year follow-up. This study will also determine the acute and long-term effectiveness of face-to-face CBT-I for insomnia in non-responders to dCBT-I on RDoC sleep outcomes relative to a comparison group post-treatment and at 1-year follow-up.
