Study type
Interventional
Description of intervention(s) / exposure
The RCT has been proposed for this study to compare the effect of a 7 week
wellbeing and performance program called ‘Mindfulness Acceptance Commitment (MAC) for
Performance Enhancement’ with a waitlist control group. Specifically, this trial will examine if the MAC program increases subjective and psychological wellbeing in Professional Ballet Dancers at The Australian Ballet. The face to face sessions will be conducted once a week for 30 minutes over a total of 7 weeks. Mode of administration: groups of approximately 10, we anticipate there will be approximately 10 participants in each of the 2 groups.

All participants will complete a baseline quantitative questionnaire after which they will be randomly allocated to either the intervention or waitlist group. The intervention group will be provided with education and mindfulness training, whilst the waitlist control group will receive the education component only. The waitlist control group will be provided with an opportunity to receive the mindfulness component after the study should they be interested. All participants will be quantitatively reassessed at week 8 completing the same initial questionnaire from week 1.

Participants will be asked to refrain from completing other psychological skills training for the duration of the intervention.
Each participant will work with the student researcher with whom they will complete 7 x 30 minute sessions.
The intervention sessions will include education about injury, performance and recovery and incorporate a mixture of theory and practice in mindfulness and acceptance and commitment training.
The waitlist control group, they will be provided with the education component including injury, performance and recovery only.
In week 8, semistructured interviews with participants from both the intervention and the waitlist control group will be conducted to gain further depth and insight into awareness of holistic wellbeing and performance.

* Participants will be provided with a voucher at the completion of week 8, funded by the student researcher, in appreciation of their time and in an attempt to encourage adherence and participation for the duration of the 8 week study period.
*Participants will be asked to not discuss their program procedures with others in order to try to control for contamination effects.
During data collection, all data from participants will be coded as participant numbers. A participant number will be placed on the data and the name of participant cut off the top of any forms. Only the participant number will be included in the data set. A master list will be created that includes names and participant numbers and will remain in a folder on the student researcher's personal, locked computer.
The student researcher holds a teacher training certificate in Mindfulness, has been trained in Acceptance and Commitment Therapy and has an accreditation in the development of wellness programs. The student researcher will also follow the MAC protocol (c.f., Gardner & Moore, 2007) that includes a stepbystep protocol for the performance enhancement program.

Behaviour
Comparator / control treatment
The waitlist control group will receive the education component only. The waitlist control group will be provided with an opportunity to receive the mindfulness component after the
study should they be interested. The waitlist comparison group will be provided with injury, performance and recovery education during the study. At the end of the 8 week study period should they be interested, the waitlist control group participants will be offered the mindfulness training and practice component.

Outcomes
Primary outcome [1] 319774 0
The primary aim of the study is to identify if there is a relationship between self reported holistic wellbeing and mindfulness practice. This will be assessed by comparing the Mindfulness questionnaire responses from week 1 and week 7. Analysis of the data will be conducted to identify any statistically significant improvements and through discussions in the semi-structured interview week 8.The questionnaires administered at week 1 at 7 have been validated and include: RESTQ-Sport, The Acceptance and Action Questionnaire II (AAQ-II), the Assessing Athletes' mindfulness skills - the Mindfulness Inventory for Sport (MIS) questionnaire and the Sport Performance Questionnaire (SPQ).
Timepoint [1] 319774 0
8 weeks
Secondary outcome [1] 369495 0
A composite secondary aim of the study is to investigate if the mindfulness intervention leads to reduced injury incidence. Injury incidence will be determined by data-linkage to medical records. The method of assessment is to identify injury incidence throughout the 7 weeks in both groups and run statistical analysis to identify if there is any difference in injury incidence between the two groups.

Efficacy
Statistical methods / analysis
To measure changes in wellness and injury incidence relative to work related
activity collected via the Athlete Management System, with ballet dancers over a 7 week period, a repeated measures ANOVA design will be used.
SPSS statistical software will be used to analyse the data. The data will be checked for missing or out of range values and that the data is univariately normally distributed. Significant baseline demographic differences (sex, age, nature of impairment) will be determined using the independent t test and Fisher exact probability test, as appropriate. Basic descriptive statistics will be used to report the demographic data of the participants.
Outcomes will be analysed using analysis of covariance on the change scores with the baseline measure of that variable used as the covariate. If the baseline variables are significantly different, they too will be entered as covariates. The mean difference within each group and the mean difference between the groups and the 95% CIs of the mean differences will also be calculated. Effect sizes and 95% CIs will also be calculated
for the change scores. To avoid bias and to maximize the randomization process, intention to treat analysis will be used.
Data from the postintervention semistructured interviews will be compared and analysed against the preintervention goals and interview using a thematic analysis and the software management tool NVivo (version 10).
Comparisons between week 1 and week 7 questionnaire responses will be reviewed via SPSS statistical analysis. Furthermore group comparisons of the intervention and waitlist
control group will be conducted to identify any differences between the two groups.
Semistructured interviews will be transcribed and thematic analysis conducted to identify themes from the experiences of the dancers.
