简要总结
'Expand Your Horizons', a self-help writing intervention that seeks to train individuals to focus on what their body can do (functionality) rather than what it looks like (appearance), has produced promising results in improving body image. However, it has not been adapted and trialled in populations with conditions affecting skin appearance. This research therefore seeks to evaluate the potential for 'Expand Your Horizons' to (1) improve body image, as measured by body and functionality appreciation; and (2) improve skin-specific outcome, as measure by skin-shame, dermatology and quality of life, in a population with dermatological conditions, using a Randomised Control Trail.
详细描述
Method of sampling/recruitment:
Recruitment from community sample, including: The University staff and student volunteers lists; Psychology undergraduate credit systems, Social media/forums; Charities; Research recruitment platforms, and a mailing lists.
Sample size:
An apriori power analysis, based on an ANCOVA, with a medium effect for the primary outcome (body appreciation) indicated a sample of 128 would be needed to achieve 80% power. Assuming an attrition rate of 50%, the total number of participants required will be 256.
In line with recommendations for evaluating interventions, we will include an internal pilot whereby we review the recruitment progress (completion) about 3 months into the trial and could then consider whether we need to make any minor or major adjustments to the recruitment strategy or study. If these substantial changes are needed, the pilot component will be written up and analysed separately to inform the next phase.

盲法说明
Participants will not be told whether they have been allocated to intervention or control condition until the end of the study. The control condition is a series of creative writing tasks, which are framed as an intervention within the introduction to the first task. This replicates previous RCTs of the same intervention in different populations (Alleva et al., 2015).

- •Individuals self-reporting that their body image is affected by their skin condition.
- •Sufficient English to complete the measures and writing exercises
- •Access to the internet.
排除标准
- •As the focus of this research is on skin disease, individuals living with visible differences as a consequence of trauma (e.g. scarring from burns or scarring from traumatic injury) are not eligible to participate in this study.

研究组 & 干预措施
Expand Your Horizons: More than my skin
Participants allocated to the intervention condition will be asked to follow the adapted instructions for 'Expand Your Horizon'. Participants will be asked to complete three 15 min writing exercises over approximately six days. Participants who complete the first exercise on Qualtrics will be sent links to and asked to complete the second and third writing exercises.
干预措施: Expand your horizons: More than my skin (Behavioral)
Control writing activity
Participants in the control condition will be asked to complete three 15 minute creative writing exercises online via Qualtucs over approximately six days. Participants completing the first writing exercise will be sent links to the second and third writing exercises.
干预措施: Creative writing activities (Behavioral)
结局指标
主要结局
Change in body appreciation
时间窗: Baseline to 1 week
The Body Appreciation Scale 2 (BAS-2, Tylka \& Wood-Barcalow, 2015) will be used to measure body appreciation and contains 10 items, and will be used to measure trait levels of body appreciation. Each item is rated on a scale of 1 (never) to 5 (always). The average score is calculated by adding each item and divided by 10, and can range between 1 and 5 with higher numbers indicating higher levels of body appreciation.
Change in body functionality appreciation
时间窗: Baseline to 1 week
The Functionality Appreciation Scale (FAS: Alleva, Tylka, \& Van Diest, 2017) will be used to measure body functionality appreciation. The FAS comprises of seven questions, and will be used to assess participants' trait levels of appreciation for their bodies' functionality (Appendix L). Each item is rated on a scale from 1 (strongly disagree) to 5 (strongly agree). The average score is calculated by adding each item and dividing by 7, and can range between 1 and 5 with higher numbers indicating higher levels of function appreciation.
