Description of intervention(s) / exposure
Brief name: Mindfulness Based Stress Reduction (MBSR) and waitlist control
Mode of delivery: MBSR group sessions will occur through Zoom (teleconferencing software) and will be approximately 1.5 hours long.
The MBSR program will run over 9 sessions (weekly for 9 weeks) each being 1.5 hours long. Additionally participants will also have homework activities that they will be asked to work on between sessions. The social worker leading the group will guide them through each mindfulness session which will have a specific area of focus.
These are:
Session 1: Course overview and What is Mindfulness?
Session 2: The mind-body connection – how our body responds physiologically to anxiety and stress.
Session 3: How to practice mindfulness meditation
Session 4: How mindfulness works with anxiety and stress
Session 5: Mindfulness for the body
Session 6: Deepening your practice – sitting meditation
Session 7: Meditation for anxiety and stress
Session 8: Loving kindness meditation
Session 9: Interpersonal mindfulness and how to make mindfulness part of your everyday life

Participants will access the MBSR program via Zoom, most likely at their place of residence.
In order to monitor adherence to the intervention a session attendance checklist will be completed each week by the social worker leading the group.

Study design
Purpose of the study

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomisation by computer
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be stratified by ambulant /non-ambulant ability using block randomization of 4, to ensure equal spread of ambulance level across treatment/wait list control groups. The Gross Motor Function Classification System (GMFCS) will be used to categorize participants as ambulant (GMFCS levels I and II) or non-ambulant (GMFCS levels III-V).

Allocation using this method will be completed using computer software.

Efficacy
Statistical methods / analysis
In order to detect an effect size of Cohen’s d =0.80 with 80% power (alpha = .05), G*Power suggests we would need 21 participants in each group, to detect meaningful change in the primary outcome of interest (difference in mean CAMS-R scores between groups).
As such we aim to recruit 24 participants for the intervention group and 24 for the waitlist control group, allowing for a 12.5% drop out rate.



Data will be analysed using SPSS (Version 25). Descriptive statistics will be used to examine the survey responses at each time point. Following this, normality will be assessed using Shapiro-wilk, visual inspection of the histogram and box plot for outliers. T-tests will be employed to compare baseline measurements of demographic and condition specific variables between groups. Analysis of covariance (ANCOVA) will then be used to compare the changes in CAMS-R between the MBSR and control groups. Paired t-tests will be run to measure change in scores within groups for the secondary outcomes (CAMS-R total scores, Anxiety, Stress, Depression scores from the DASS-21; DERS total scores; pain intensity and interference scores; and point changes in ratings on a 10-point rating scale, across 5 individual specific anxiety inducing situations). P-values of <0.05 will be considered statistically significant. Where assumptions are not met, non-parametric Wilcoxon Signed Rank Test will be conducted, and change scores will be calculated.

Summary
Brief summary
The objective of this study is to measure the effectiveness of a Mindfulness Based Stress Reduction (MBSR) program delivered via telehealth in developing mindfulness knowledge and practice, and in turn reducing anxiety, depression, stress and pain, and improving emotion regulation, in adults with cerebral palsy (CP). Participants (n=48) will be randomly allocated to either an online MBSR Group Program (treatment) or a waitlist control group. For feasibility of group interaction by telehealth, the MBSR treatment group will be divided into 3 groups (8 participants in each group). The MBSR Program led by a social worker includes content focused on developing mindfulness skills. The MBSR program consists of 9 x 90-minute sessions, run over 9 weeks provided by telehealth practice. Participants will be assessed at baseline (T1), at the conclusion of the course (T2), and then re-assed 8 weeks after the program has finished (T3).

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
Due to the small sample size there would be concern that participant data could be identifying. We do not have ethics approval to allow IPD sharing.
