Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a 2-group design (control & intervention) assessing the effect of an online writing intervention.
Exposure to intervention occurs once only and for approximately 30 minutes.
Intervention - structured writing with self-compassionate prompts about difficult body image experiences after treatment for breast cancer. The writing prompts are delivered in an online format via a website accessed by participants allocated to the experimental condition. To monitor time spent undertaking the intervention, participants are asked to record their start and finish time on the website.

Behaviour
Comparator / control treatment
Control group participants will receive access to a plain version of the website with an unstructured writing activity that will be matched for length and activity duration. The total length of the writing activity is expected to take approximately 30 minutes.

Efficacy
Statistical methods / analysis
According to the study design, participants are divided into subgroups: Stream A (breast cancer only) and Stream B (breast cancer related lympheodema). The following estimates were used to recruit required participant numbers:

Stream A: 200 women diagnosed with breast cancer would be recruited, who will then be divided into two groups of 100 participants (control and experimental). Leary et al (2007) obtained an r-squared of .08 which is equivalent to Cohen's d of .58, this is regarded as a medium effect size. Using two conditions, samples of this size have been shown to be adequate for the purposes of research.

Stream B:100 women diagnosed with breast cancer-related lymphoedema would be divided into two groups of 50 participants (control and experimental). A priori calculation of the minimum required sample size given a probability level of 0.05, an anticipated effect size of .58 and 80% power is N=96 (n=48 per group).

Using these estimates a total N = 300 was considered adequate for the purposes of the study

Upon obtaining data from 300 participants, maximum likelihood linear mixed models will be applied to these data to assess change over time.
