Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The two interventions which will be examined include My Changed Body (Sherman et al., 208) and Expand Your Horizon (Alleva et al., 2016). In both intervention conditions, participants will spend up to 30 minutes completing a writing exercise.

In the My Changed Body intervention, participants will first be asked to recall and write about a distressing event following their cancer diagnosis. Next, participants will be guided by five self-compassionate prompts, which will first involve focusing on how their body has changed since their cancer diagnosis, before moving to a broad self-compassionate perspective in which they show kindness to their experience the same way they would to a friend in a similar situation. Participants will then write about ways in which other female cancer survivors may have similar experiences, before moving on to examine their feelings using a bigger perspective and putting space between the event and their reactions. Participants will finish the writing exercise by writing a self-compassionate letter to themselves. The intervention will consist of a single session of up to 30 minutes writing duration.

In the Expand Your Horizon condition, participants will be introduced to the concept of body functionality by reading a short description describing the meaning of body functionality, and by being provided with examples of different types of body functions. Participants will then be guided through the writing exercise by six writing prompts which will focus on different components of body functionality. Participants will be asked to reflect on and to write about the importance of each body function to them. Examples of relevant body functions will be provided for each writing prompt. The intervention will consist of a single session of up to 30 minutes writing duration.

The writing tasks’ content will also be analysed for this study to ensure participants are writing in accordance with the intervention instructions. In addition, the word count of each writing task will be captured to measure participant engagement.

The study will be conducted online using Qualtrics. As such, participants will be free to choose which location they wish to complete the study in.

Comparator / control treatment
Participants who are randomly allocated to the active control group will engage in a neutral writing exercise which will also be completed online via Qualtrics. Participants will be asked to spend up to 30 minutes writing about different rooms in their house as though they are describing it to someone who has never seen their house before. Participants will be guided through the exercise by six writing prompts, each of which will ask them to describe a different room (e.g., bedroom, lounge room, bathroom, kitchen...etc). Participants will be asked to be detailed as possible in their writing and to include information such as the size of each room, the number of windows, colour of furniture, and colour of walls. This neutral writing exercise follows that of Pennebaker and Beall (1986) whom asked participants to provide descriptions of their living rooms. However, for the purpose of ensuring consistency across intervention conditions, the writing exercise has been modified for the present study by asking participants to describe five additional rooms.

Outcomes
Primary outcome [1] 335134 0
Trait Body Appreciation as measured by the Body Appreciation Scale-2 Short Form (BAS-2SF; Tylka et al., 2022)
Timepoint [1] 335134 0
Baseline, 1-week post intervention completion (primary time point), and 2-weeks post intervention completion
Primary outcome [2] 335135 0
State body appreciation will be measured using a state version of the Body Appreciation Scale-2 Short Form (BAS-2SF; Tylka et al., 2022). State body appreciation will be measured using 100 millimetre visual analogue scales with two anchor points (0=not at all, 100=very much). The wording of the BAS-2SF items will be adjusted to present tense in order to obtain a measure of state, rather than trait body image.

Secondary outcome [1] 423216 0
Trait Functionality appreciation measured using the Functionality Appreciation Scale (FAS; Alleva et al., 2017)
Timepoint [1] 423216 0
Baseline, 1-week post intervention completion, 2-weeks post-intervention completion

Secondary outcome [5] 423221 0
State functionality appreciation will be measured using 2 items selected from the Functionality Appreciation Scale (FAS; Alleva et al., 2017) using 100-millimetre visual analogue scales with two anchor points (0=not at all, 100=very much). The wording of the items will be changed to present tense to obtain a measure of state body image.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The allocation sequence will be concealed from the researcher as it will be randomly generated by Qualtrics, which uses a randomizer sequence to assign participants to one of three conditions if they meet the eligibility criteria.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The Qualtrics randomiser will be enabled to ensure simple randomisation to intervention condition.
Masking / blinding

Efficacy
Statistical methods / analysis
An a priori power analysis was conducted using G Power. An effect size of 0.5 was selected based on previous findings by Alleva et al. (2016). Parameters included 3 groups, 4 timepoints, significance level of 0.05, power level of 0.8, and 20% estimated attrition rates. Based on these parameters, 98 participants (n = 49 per group) will be needed to detect an effect. The study will utilise a quantitative based approach. Descriptive statistics will be used to describe the sociodemographic and clinical characteristics of the sample, and attrition rates. Chi square tests will be used to examine baseline differences between intervention groups (My Changed Body vs Expand Your Horizon) on categorical demographic variables such as cancer type and cancer treatment, and on completers versus drop-outs. Independent samples t-tests will be used to examine baseline differences on continuous variables (i.e., age and outcome variables). Linear mixed model analyses will be used to explore changes over time between the intervention groups on each outcome variable. Cohen’s d will be used to determine the strength of the intervention using between-group effect sizes.
