This is a two-arm, parallel-group randomized controlled feasibility trial involving 40 community-dwelling adults with chronic stroke and ongoing sleep or circadian difficulties. Participants will be randomly assigned in a 1:1 ratio to either an individualized behavioral sleep intervention or an attention-matched health education program.

Before randomization, participants will complete questionnaires assessing sleep and related health outcomes, maintain a sleep diary, and wear a wrist-worn activity monitor for seven days. Participants will then attend six weekly, individual, face-to-face sessions lasting approximately one hour each.

The behavioral sleep intervention will provide individualized education and behavioral strategies to support sleep and daily sleep-wake functioning following stroke. The comparison program will provide education about stroke, sleep, and general health. The two programs will be matched in session frequency and duration.

Following the six-week program, participants will repeat the questionnaires, sleep diary, and seven-day wrist-monitoring assessment. Participants will also provide feedback about their experiences with the study and program.

The trial will evaluate recruitment, retention, attendance, intervention delivery, acceptability, fidelity, and safety. Preliminary changes in sleep and sleep-wake outcomes will also be examined.
