Redefining Insomnia: A Comparison of Categorical and Dimensional Approaches

If you agree to join the study, you will be asked to complete the following research procedures. There will be a virtual screening visit that will take approximately 2 hours to complete. During this visit, all of the study procedures will be described to you in detail, you will have the opportunity to ask questions and sign the consent form if you are comfortable with continuing in the study. After you sign the consent form, you will be asked to complete some questionnaires and have two clinical interviews which will ask questions about your sleep, thoughts, and feelings. You will then have your sleep monitored at home for two weeks which will include wearing a wrist-worn device known as an actiwatch on your non-dominant wrist while completing a daily diary. The last step will be a sleep study that will be in your home. Study staff will work with you to schedule your in-home sleep study. On the evening of your sleep study they will come to your home and place wires on your head, face, and body to monitor your sleep. In the morning, staff will return to remove the wires, perform a blood draw, have you complete some questionnaires, and some computer tests. Once you have completed all of the morning tasks, the study team will leave. If you agree, the study team will come back a month later to repeat the home portion of the study. Your participation is over once you have completed the in-home portion of the study (or the optional second in-home).
