Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All participants will go through eight weekly (1 hour) structured mindfulness sessions. All sessions will be in groups of up to eight participants, and all sessions will involve direct face-to-face contact at Murdoch University (Perth, Western Australia). All sessions will be facilitated by the main student researcher for this study (Leong-Min Loo), who is a provisionally registered clinical psychology PhD student at Murdoch University, Perth, Western Australia. The sessions will also have a co-facilitator (a provisionally registered clinical psychology Masters student). Sessions are supervised by a clinical psychologist. All sessions are structured - with a brief introduction, two scripted mindfulness activities, and two discussion segments. Materials are compiled into a comprehensive protocol. Mindfulness activity scripts are adapted from the book ‘The Mindful Way through Depression: Freeing Yourself from Chronic Unhappiness’.
Participants in this intervention condition (hereby labelled as "sounds") will attend to moment-to-moment progression of unique sound tracks, with each track lasting approximately five to eight minutes long. Each track will only be played once throughout the eight sessions, and each session will have two tracks, except for the eighth session, which will have only one track. All tracks will have low arousal and positive valence.
Participants will be given the Outcome Rating Scale (ORS) at the start of the session. They will be given the Five Facet Mindfulness Questionnaire (FFMQ), Brief Resilience Scale (BRS), Depression Anxiety Stress Scale-21 (DASS-21), and a session rating questionnaire, at the end of the session. Participants will also be emailed handouts containing a summary of the session and suggested mindfulness activities, after every session.

Comparator / control treatment
All participants will go through eight weekly (1 hour) structured mindfulness sessions. All sessions will be in groups of up to eight participants, and all sessions will involve direct face-to-face contact at Murdoch University (Perth, Western Australia). All sessions will be facilitated by the main student researcher for this study (Leong-Min Loo), who is a provisionally registered clinical psychology PhD student at Murdoch University, Perth, Western Australia.

All sessions are structured - with a brief introduction, two scripted mindfulness activities, and two discussion segments. Materials are compiled into a comprehensive protocol. Mindfulness activity scripts are adapted from the book ‘The Mindful Way through Depression: Freeing Yourself from Chronic Unhappiness’.
First, participants will go through two sessions of mindfulness orientation. They will be given information on the theory behind concepts of mindfulness, and will engage in some guided mindfulness exercises, such as a ten-minute Body Scan, and Mindful Eating. After the two orientation sessions, participants will engage in various mindfulness activities focusing on the breath and its accompanying bodily sensations (internal attentional targets).
Participants will be given the Outcome Rating Scale (ORS) at the start of the session. They will be given the Five Facet Mindfulness Questionnaire (FFMQ), Brief Resilience Scale (BRS), Depression Anxiety Stress Scale-21 (DASS-21), and a session rating questionnaire, at the end of the session. Participants will also be emailed handouts containing a summary of the session and suggested mindfulness activities, after every session.

Secondary outcome [5] 326547 0
Heart rate variability (as an index of emotional regulation and flexibility) is monitored using finger sensors attached to the index, third and ring fingers on the participant's preferred hand (right or left). The sensors are in turn linked to the Alive Programme (Somatic Vision), installed on a Windows 7 laptop. The duration of monitoring is five minutes at each timepoint.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Numbered containers (1 for "control" and 2 for "sounds")
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Eligible participants were randomly and individually assigned to one out of four group timeslots. Simple randomisation was then done using folded slips of paper labelled with session timeslots. Two session timeslots correspond to "control", another two session timeslots correspond to "music". The folded slips of paper were then shuffled and tossed into each of the labelled containers (Ctrl for "control" and Mus for "sounds"). Each slip is then opened one by one.
Masking / blinding

Statistical methods / analysis
A priori power analysis has not been calculated.
Quantitative data (mindfulness skills, resilience, depression, anxiety and stress) will be converted and analysed via SPSS (PASW) Statistics, following intention to treat analyses, using linear mixed modelling approaches. In addition to intention to treat analyses, additional correlation and regression slope analyses will be carried out to determine relationships between variables.
