Effects of Messaging App Reminder on the Compliance of Zero-Time Exercise (ZTEx)
Effects of Messaging App Reminder on the Compliance of Zero-Time Exercise (ZTEx): A Nested Proof-of-concept Pilot Study
Study Overview
Status
Conditions
Detailed Description
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.

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Hong Kong residents,
- ethnic Chinese aged 18-65 years with the ability to communicate in Cantonese or Putonghua,
- who fulfil the DSM-5 diagnostic criteria for insomnia disorder according to a validated diagnostic tool, the Brief Insomnia Questionnaire (we include primary insomnia because it is more homogenous and less complicated than comorbid insomnia; if ZTEx is found to be effective for primary insomnia, then comorbid insomnia can be targeted in future studies),
- scored at least 10 points in the Insomnia Severity Index,
- are ambulant and can independently perform daily activities,
- are physically inactive, defined as not having participated in at least 150 min of moderate intensity or 75 min of vigorous intensity physical activity a week, or the equivalent combination over the previous 3 months by self-report
- have a smartphone compatible with WhatsApp, and
- willing to give informed consent
Exclusion Criteria:
- any current diagnosis fulfilling the DSM-IV criteria of a major depressive disorder, generalized anxiety disorders, post-traumatic stress disorder, panic disorder, substance use disorders, or schizophrenia as screened using the Chinese version of the Structured Clinical Interview for DSM-IV;
- other sleep disorders, including circadian rhythm disorder, narcolepsy, obstructive sleep apnoea (OSA), and restless leg syndrome (RLS)/periodic leg movement disorder (PLMD) as determined based on cut-off scores (≥ 7 on narcolepsy; ≥ 8 on circadian rhythm disorder; ≥ 15 on OSA; ≥ 7 on RLS/PLMD) using SLEEP-50. If in doubt, subjects will be referred to our team psychiatrist (KF Chung) for further assessment;
- any current medical conditions or side-effects of medication that are contributing significantly to the subject's insomnia;
- taking medications or currently participating in other psychotherapies for insomnia or other psychiatric disorders;
- impaired cognitive functioning (<22 points in HK-MoCA) or with difficulty in giving consent or understanding instructions;
- pregnant;
- shift work;
- whose physical condition is such that physicians recommend that they refrain from exercising; and
- fulfilling the criterion for obesity for Asians (body mass index, of 27.5 or above)

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Zero Time Exercise training + WhatsApp anti-inertia reminders
Subjects in this group will receive daily WhatsApp anti-inertia reminders from the research assistant to remind and encourage them to practice Zero Time Exercise.
|
Zero Time Exercise encourage people to increase physical exercise by simple movements that can be done any time at any places. We offer a 2-session training course to train the subjects to do zero-time exercise. In addition, WhatsApp anti-inertia reminders will be sent daily by the research assistant to remind and encourage the participants to practice the Zero Time Exercise. |
Active Comparator: Zero Time Exercise training alone
Subjects in this group will not receive any WhatsApp reminders from week 8 to 24.
|
Zero Time Exercise encourage people to increase physical exercise by simple movements that can be done any time at any places.
We offer a 2-session training course to train the subjects to do zero-time exercise.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Insomnia Severity Index
Time Frame: week 8, week 16, week 24
|
The subjects rate the severity of insomnia, the distress, and the functional impairment associated with insomnia on a 5-point scale.

The higher the score, the worse the outcome is.
|
week 8, week 16, week 24
|
Change in the intervention adherence
Time Frame: week 8, week 16, week 24
|
Patients will be told to record their daily physical activities or sleep health hygiene compliance onto the log.
|
week 8, week 16, week 24
