The aim of this study is to pilot test a comprehensive, personalized, media-augmented telehealth intervention ("SWISH") designed to improve sleep health among shift workers.

Night shift nurses with insomnia who meet all study criteria will receive insomnia therapy, modified for shift workers that is designed to improve sleep health among shift workers by targeting shift workers' unique sleep health problems which manifest during both sleep and wake. Participants will be randomized to either SWISH, a multicomponent behavioral intervention based on cognitive behavioral therapy for insomnia that is individually administered via telehealth across approximately weekly sessions that range in length from 30-60 minutes, or delayed treatment control, which will involve weekly assessments but no active treatment until the delay period is over, at which point they will be offered the intervention. The therapy will be conducted over telehealth by interventionists trained in behavioral sleep medicine.

Inclusion Criteria:

• Provision of signed and dated informed consent form
• Any gender; Ages 18-65
• Currently employed as a nurse or nursing staff member (e.g., CNA) in the United States
• Currently have shift work schedules (i.e., stable night shift or rotating shifts that include nights, >=2 nights/week) and have worked shift work >=2 nights/week for at least 3 months
• Expect to have a shift work schedule >=2 nights/week over the next 6 months
• endorse poor sleep, as evidenced by T-score >=60 on the PROMIS Sleep Disturbance OR Sleep-Related Impairment measure
• Have daily access to the internet on a smartphone, table, or computer; and
• Can read and write in English.

Exclusion Criteria:

• Conditions which make study treatment likely to be ineffective. For example, current chronic use of medications that interfere with sleep, alcohol or substance use disorder, or thought disorder (as determined by DIAMOND psychiatric interview), unstable sleep or medical conditions that necessitate additional medical care not provided by study treatments (e.g., known untreated sleep apnea).
• Presence of safety risk or condition in which study participation may result in increased risk to safety (e.g., elevated risk for suicide, self-reported uncontrolled seizure disorder, history of manic or hypomanic episode, current pregnancy),
• Currently receiving non-pharmacological treatment for insomnia (e.g., cognitive behavioral therapy for insomnia) and/or current unstable hypnotic/alerting medication use OR
• Currently participating in other research studies with substantial overlap in terms of methods/procedures (e.g., PI's ongoing study "Piloting an Adaptation of Cognitive Behavioral Therapy for Insomnia for Shift Workers (CBTI-Shift)"

De-identified data may be uploaded to a data repository to make it accessible for publication.

Data will become available within 2 years after the publication of the results pertaining to the primary aims and will be available for at least 2 years.

Data will be shared only with investigators who have a clear and rigorous analytic plan and who sign a data use agreement with the principal investigator.

Participants are asked to refrain from mentioning any information about the treatment they receive when interacting with the investigator or outcomes assessors. Participants are asked not to share details of their treatment with other individuals at their workplace.
