The goals of this clinical trial are to assess the feasibility of an internet-based Cognitive Behavioral Therapy for Insomnia (CBT-I) and Motivation Interviewing (MI) intervention for individuals aged 18 to 64 with mild to moderate insomnia, and/or mild anxiety/depression. The main questions it aims to answer are: * Can internet-based CBT-I effectively improve sleep quality and reduce insomnia symptoms? * Can internet-based CBT-I effectively improve sleep efficiency, sleep onset latency (SOL), and wake after sleep onset (WASO)? * Is CBT-I treatment feasible to carry out remotely? What are the percentages of participants who dropped out of the study? * Is internet-based CBT-I financially feasible compared to the traditional CBT-I intervention? Eligible participants would be invited to participate in the research and randomised into two groups: Intervention and Waitlist Control. Both groups will have their baseline Insomnia Severity Index and Sleep Condition Indicator assessed prior to the main part of the research. Participants in the Intervention group will go through 4 CBT-I sessions over the course of 4 weeks. These sessions will be delivered online by trained lay-person coaches, supervised directly by an experienced coach specialising in CBT-I. The Intervention group will also keep a sleep diary. At the end of the intervention, the investigators will interview 10 individuals to learn more about their experiences during the study. Participants in the Waitlist Control Group will receive the same intervention after the end of the study. This group acts as a control for the Intervention group.
