Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The primary research question is as follows:
What is the effectiveness of the iMBT in relation to improvements on depressive symptoms among people with clinical depression, relative to a usual care control after the intervention and in 3-month follow-up?
Secondary questions include the following:
Which facet(s) of mindfulness (i.e., observe, describe, act with awareness, non-react and non-judgement) improved during the intervention? How does the growth trajectory of different facets of mindfulness relate to the improvement of well-being and reduction of ill-being?
The investigators hypothesize that:
H1 Participants in iMBT group will have greater reduction in depressive symptoms and increase in all facets of mindfulness and mental well-being, than the usual care group at post-intervention, and 3-month follow-up.
H2 Using latent growth analysis, the intraindividual growth trajectory of the monitor and acceptance facets of mindfulness would mediate the effect of iMBT on the intraindividual changes in depressive symptoms.
H3 Using multi-group analysis, in accord with Acceptance and Monitor theory, the relationship between the growth trajectory of monitor facets of mindfulness and the growth trajectory of depressive symptoms will be moderated by the level of acceptance. People with greater acceptance of inner experience will benefit more from the change of monitor facets of mindfulness in iMBT.

1.2 Mindfulness-based Training as an Internet delivered Intervention for People with Depression In addition to iCBT, Internet-based mindfulness-based training (iMBT) has also gained evidence in improving mental well-being and reducing psychological distress. Mindfulness is defined "paying attention in a particular way: on purpose, in the present moment, and nonjudgmentally" 17,18. In the context of understanding the beneficial effect of mindfulness on depression, it is theorized that mindfulness training reduced depression through encouraging individuals to notice experiences regardless of its valence labelled, and to approach those experiences with gentleness, curiosity and interest without suppressing, judging, or pushing these experiences away 19. In turn, repetitive negative thinking, which involves cognitive over-engagement in attempt to control unpleasant inner experiences, would be attenuated by the facilitation of individuals' processing of their affective experiences17,20. Moreover, through observing that different experiences come and go over time, mindfulness practitioners come to know the impermanent and transitory nature of the inner experience and realize that it is not always necessary to react.
A recent meta-analysis that included 209 studies with 12,145 participants concluded that mindfulness-based intervention is an effective treatment for various psychological problems, and is especially effective for reducing depression, anxiety and stress21. Evidence of online mindfulness-based intervention has demonstrated its effectiveness among community samples and subclinical populations with elevated depressive symtoms23,24. In addition, iMBT may be more acceptable than intervention using the traditional cognitive behavioral approach. As reported in a recent study, intervention with mindfulness element was chosen as the first option of intervention by over 80% of people with depression/anxiety. Moreover, nearly half of the participants in a study reported preference of online formats for mindfulness interventions over group/individual formats28.
Given its acceptability and preference by individuals with mental health needs and its promising effects in reducing depressive and anxiety symptoms, another critical question lies in examining how MBT works so that further refinement of such approach can be made based on its theoretical roots and mechanism of change. The precise mechanisms underlying the effect of mindfulness have received recent theoretical attention19,29,30. Despite not having abundant studies, recent meta-analysis of mediation studies with 12 RCTs identified consistent evidence for the change in mindfulness as a mechanism underlying MBIs31. However, simply identifying mindfulness as the mechanism of change in MBT is too crude and intuitive. Further unpacking the effects of mindfulness is necessary to understand the process through which individuals experience changes. One possibility is to examine specific effect of each facet in mindfulness (i.e., observe, describe, act with awareness, non-react and non-judgement). Correlational study suggested that different facets of mindfulness have differential relationships with various psychological variables 32. Although most facets of mindfulness are frequently found to be associated with reduced psychological distress, the "observe" facets is often uncorrelated or even positively correlated with mood symptoms 33. In accord with the Acceptance and Monitor theory19, a recent study showed high observing skills was correlated with higher depressive symptoms with low acceptance. Yet, high observing skills in combination with high acceptance correlated with increased adaptive cognitive processing tendencies 34. Consequently, it is important to examine relationships between change of mindfulness and that of psychological symptoms at the facet level to provide a more fine-grained perspective on the contribution of mindfulness. This could also facilitate refinement of iMBT.
1.3 Aims and hypotheses The research goals of this randomized controlled trial are to determine the feasibility and the mechanism of change of iMBT that has been developed using the Acceptance Checklist for Clinical Effectiveness Pilot Trials (ACCEPT) framework35.
The primary research question is as follows:
What is the effectiveness of the iMBT in relation to improvements on depressive symptoms among people with clinical depression, relative to a usual care control after the intervention and in 3-month follow-up?
Secondary questions include the following:
Which facet(s) of mindfulness (i.e., observe, describe, act with awareness, non-react and non-judgement) improved during the intervention? How does the growth trajectory of different facets of mindfulness relate to the improvement of well-being and reduction of ill-being?
The investigators hypothesize that:
H1 Participants in iMBT group will have greater reduction in depressive symptoms and increase in all facets of mindfulness and mental well-being, than the usual care group at post-intervention, and 3-month follow-up.
H2 Using latent growth analysis, the intraindividual growth trajectory of the monitor and acceptance facets of mindfulness would mediate the effect of iMBT on the intraindividual changes in depressive symptoms.
H3 Using multi-group analysis, in accord with Acceptance and Monitor theory, the relationship between the growth trajectory of monitor facets of mindfulness and the growth trajectory of depressive symptoms will be moderated by the level of acceptance. People with greater acceptance of inner experience will benefit more from the change of monitor facets of mindfulness in iMBT.
A two-armed parallel RCT following CONSORT statement1 will be conducted to examine the efficacy of an Internet-based mindfulness-based training (iMBT) to a treatment-as-usual control group (TAU). Eligible participants will be randomized to either iMBT or TAU by block randomization with block number of 6 with allocation ratio of 1:1. Intervention (iMBT) will be delivered over a 6-week period via an internet e-learning mental health platform. Both groups will be assessed at the following time points: (1) before intervention (T0), (2) 2,4 weeks since the commencement of group (T1,2), (3) 6 weeks after (i.e., when the intervention ends) (T3), (4) at 3-month follow-up(T4).

Internet-based mindfulness-based training group (iMBT)
Participants in the iMBT group will be expected to complete an Internet-based mindfulness-based training delivered over a 6-week period via an internet e-learning mental health platform. They will be assessed at four different time points:
(1) before intervention (T0), (2) 2,4 weeks since the commencement of group (T1,2), (3) 6 weeks after (i.e., when the intervention ends) (T3), (4) at 3-month follow-up(T4).
Internet-delivered Mindfulness Based Training (iMBT)
The iMBT developed for this study will be adapted from our team's previous study and the manual of mindfulness based cognitive therapy. The program is designed to be brief in nature, for example, participants will be asked to practice meditations for 15 minutes a day instead of the original 45 minutes a day, and each module is shortened to approximately 1 hour instead of the original 2.5 hours.
This iMBT is comprised of six weekly modules on education about mindfulness, guidance on using mindfulness skills to manage symptoms, guided meditations (e.g., mindful breathing, mindful eating, mindful walking, body scan, acceptance, choiceless awareness and disengaging from thoughts exercise), and guidance on using informal mindfulness skills in day-to-day life. Readings, audio and graphics are included to explain the concept of mindfulness and overcome common difficulties associated with mindfulness practice.
Treatment-as-usual control group (TAU)
The TAU group will be advised to seek assistance from their usual healthcare provider when needed. They will be offered access to the Internet-based mindfulness-based course content after the study has ended.
No interventions assigned to this group
