简要总结
This is a proof-of-concept pilot nested in the RCT titled, 'Zero-time Exercise on Inactive Adults With Insomnia Disorder'. It aims to evaluate the effects of a simple WhatsApp intervention on exercise adherence and on sleep and related outcomes.
详细描述
This is the second phase of another study - 'Zero-time Exercise on Inactive Adults With Insomnia Disorder'.
In the first phase (baseline to week 8), 136 subjects will be randomly allocated to the ZTEx intervention or the sleep hygiene education (SHE) comparison group. They will receive two 2-hour ZTEx training or SHE lessons and practice ZTEx or follow the sleep hygiene instruction for 24 weeks.
The second phase of the study (weeks 9-24)will commence after completion of the assessment of the RCT at week 8. Subjects in the Zero-time Exercise (ZTEx) group will be randomly divided into either an ZTEx with WhatsApp reminder (ZTEx+R) group or an ZTEx without WhatsApp reminder (ZTEx alone) group to evaluate the effects of WhatsApp reminders on exercise adherence and sleep and related outcomes.
