What this trial studies
This pilot randomized trial will enroll 32 older Korean immigrants with chronic insomnia and randomize them 1:1 to a culturally adapted, manual-based CBT-I program (SLEEP-OK) or an information-only control. The intervention is delivered in Korean through community partner sites and focuses on culturally tailored sleep education and behavioral strategies. Outcomes include feasibility measures, acceptability, and sleep health outcomes measured at baseline and immediately after the intervention. Results will inform whether a larger efficacy trial is warranted.
Who should consider this trial
Good fit: Ideal candidates are Korean-born U.S. residents aged 60 or older who speak, read, and write Korean, have significant insomnia (ISI ≥ 15), intact cognition (MoCA ≥ 23), can ambulate, and have low risk for untreated moderate obstructive sleep apnea.
Not a fit: People with untreated moderate-to-severe obstructive sleep apnea, those who are bedbound, those who do not meet DSM-5 criteria for insomnia, or those unable to participate in Korean-language sessions are unlikely to benefit from this intervention.
Why it matters
Potential benefit: If successful, the program could improve sleep quality among older Korean immigrants and expand access to culturally appropriate, non-drug insomnia care.
How similar studies have performed: Standard CBT-I has shown strong benefits for older adults, but culturally adapted CBT-I programs for Korean immigrants are novel and have limited prior evidence.
