About this study

Official title: Effects of Messaging App Reminder on the Compliance of Zero-Time Exercise (ZTEx): A Nested Proof-of-concept Pilot Study

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Zero Time Exercise training + WhatsApp anti-inertia remindersOther

    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.

  • Zero Time Exercise training aloneOther

    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 being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Insomnia Severity Index

    The subjects rate the severity of insomnia, the distress, and the functional impairment associated with insomnia on a 5-point scale. The score ranges from 0 to 28. The higher the score, the worse the outcome is.

    Measured: week 8, week 16, week 24

  2. Change in the intervention adherence

    Patients will be told to record their daily physical activities or sleep health hygiene compliance onto the log.

    Measured: week 8, week 16, week 24

Secondary outcomes (13)
  1. Sleep diary (7-day)

    The standardized sleep diary records the daily bedtime and rising time, from which the total time in bed (TIB) can be calculated.

    Measured: week 8, week 16, week 24

  2. Hospital Anxiety and Depression Scale

    The Hospital Anxiety and Depression Scale is a 14-items self-administered questionnaire, which assesses the severity of depressive and anxiety symptoms. The score ranges from 0-21 for either depression or anxiety. The higher the score, the worse the outcome is.

    Measured: week 8, week 16, week 24

  3. Multidimensional fatigue inventory-20

    Multidimensional fatigue inventory-20 is a 20-items self-report instrument designed to measure severity of fatigue. The score ranges from 20 to 100. The higher the score, the worse the outcome is.

    Measured: week 8, week 16, week 24

  4. Actigraphy (7-day)

    Actigraphy measures wrist movements to assess sleep or waking state, is accomplished through an accelerometer in a wrist worn device.

    Measured: week 8, week 16, week 24

  5. Accelerometer (7-day)

    Accelerometer measures wrist movements to assess the physical activity levels.

    Measured: week 8, week 16, week 24

  6. Change in WAIS-IV Digit Span forward test

    Change in Wechsler Adult Intelligence Scale, 4th edition (WAIS-IV) Digit Span forward test score will be used to measure the attention function.

    Measured: week 8, week 16, week 24

  7. Change in WAIS-IV Color Trails Test

    Change in Wechsler Adult Intelligence Scale, 4th edition (WAIS-IV) Color Trails Test score will be used to measure the attention function.

    Measured: week 8, week 16, week 24

  8. Change in WAIS-IV Stroop color-word Test

    Change in Wechsler Adult Intelligence Scale, 4th edition (WAIS-IV) Stroop color-word Test score will be used to measure the attention function.

    Measured: week 8, week 16, week 24

  9. Change in the Hong Kong List Learning Test (HKLLT)

    Change in HKLLT Test score will be used to measure the memory function.

    Measured: week 8, week 16, week 24

  10. Change in Digit Span-backward and forward test

    Change in Digit Span-backward and forward test score will be used to measure the memory function.

    Measured: week 8, week 16, week 24

  11. Change in the interference index of Color Trails Test

    Change in the interference index of Color Trails Test score will be used to measure the executive function

    Measured: week 8, week 16, week 24

  12. Change in the interference index of Stroop color-word Test

    Change in the interference index of Stroop color-word Test score will be used to measure the executive function

    Measured: week 8, week 16, week 24

  13. Change in the Wisconsin Card Sorting Test

    Change in the Wisconsin Card Sorting Test score will be used to measure the executive function

    Measured: week 8, week 16, week 24

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Insomnia Severity Index (time frame: week 8, week 16, week 24). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
