Description of intervention(s) / exposure
This study recruited from a larger Australian cohort (a study registered under ACTRN12619001706167) and used a single-blind, longitudinal two-arm randomised controlled design to evaluate the value and impact of incorporating PRS information into melanoma risk assessments.

Participants were randomised to receive a ‘traditional’ melanoma risk score based on clinical and environmental risk factors (control group), or ‘personalised’ melanoma risk score based PRS, clinical, and environmental risk factors (intervention group). Participants received their melanoma risk scores in the form of an information booklet and were offered a follow-up appointment to discuss the results. Individuals in the control group were offered a personalised risk booklet after 12 months.

For the intervention group, personalised risk scores were calculated using PRS scores and traditional risk factors (nevus counts, hair colour, first-degree family history of melanoma, personal history of melanoma and keratinocyte (non-melanoma) skin cancer, previous sunbed use, age, sex and country/state of birth) previously identified as significant predictors of melanoma risk. The final personalised risk score were developed using established methodology to evaluate the incremental contribution of genetic risk factors (SNPs), together with the traditional clinical and lifestyle factors. Ten-year risk scores were calculated based on previously described methods (doi.org:10.1111/jdv.19279; doi.org:10.1111/bjd.18524; doi: 10.1016/j.jid.2018.05.023) and adjusted according to melanoma incidence rates by geographical location, age, and sex using the Australian Institute Health and Welfare statistics. A genetic counsellor created each of the booklets and was available to discuss the results, upon request.

A mixed methods approach assessed impacts of receiving traditional versus personalised melanoma risk scores. Questionnaires were administered at baseline, 1-month, and 12-months to capture psychosocial (i.e. perception of risk and control, empowerment, genetic testing specific distress, uncertainty and experience, and personal utility) and behavioural outcomes (i.e. communication with healthcare professionals, attitudes and confidence toward risk management, sun-protective behaviours, skin surveillance and accessing informational resources). Qualitative interviews will be conducted with control group participants who elect to receive their PRS information at 12-month follow-up, to explore if they perceived any additional value in receiving PRS information.

Adherence was not an issue for this study as participants received a single risk booklet after baseline surveys were completed. Additionally, the control cohort will receive a second booklet (PRS+traditional risk factors) at 12 months. This information is not available through other avenues so we do not need to worry about control arm participants pursuing the PRS information through another avenue.

Personalisation of the data is made possible as participants provided demographic and clinical information when they participated in the parent study (ACTRN12619001706167). At that time they also provided a saliva sample for genetic analysis. This group were invited to participate in this study in January and February of 2024 to evaluate the significance of receiving this information. Surveys were completed at baseline, one month following receipt of results and will be completed at 12 months following result disclosure. Qualitative interviews will also be completed after 12 months for the control group.

Prevention
Comparator / control treatment
The control arm received a ‘traditional’ melanoma risk score designed specifically for this study, based on clinical and environmental risk factors, which were provided as part of the parent study (ACTRN12619001706167). These include nevus counts, hair colour, first-degree family history of melanoma, personal history of melanoma and keratinocyte (non-melanoma) skin cancer, previous sunbed use, age, sex and country/state of birth).
Participants received their melanoma risk scores in the form of a custom designed information booklet and were offered a follow-up appointment (in person or online) to discuss the results with the leading genetic counsellor. Individuals in the control group will be offered a personalised risk booklet after 12 months.
Online questionnaires were administered at baseline, 1-month, and will be administered at 12-months to capture psychosocial (i.e. perception of risk and control, empowerment, genetic testing specific distress, uncertainty and experience, and personal utility) and behavioural outcomes (i.e. communication with healthcare professionals, attitudes and confidence toward risk management, sun-protective behaviours, skin surveillance and accessing informational resources). Qualitative interviews will be conducted with control group participants who elect to receive their PRS information at 12-month follow-up, to explore if they perceived any additional value in receiving PRS information.
There are no strategies needed to monitor adherence as there are no other available alternatives for participants.
The control group received a information booklet designed for this study, summarising their traditional risk score, that incorporated individual clinical and lifestyle factors relating to melanoma risk. The information booklet was eighteen pages long, and covered the following topics; traditional risk factors for melanoma, a traditional risk assessment, an explanation on how the risk score was calculated, information on impact for family, information and resources for how to manage risk, and who to contact for more information.
For individuals with no personal history of melanoma, risk scores were based on traditional risk factors (nevus counts, hair colour, first-degree family history of melanoma, personal history of keratinocyte (non-melanoma) skin cancer, previous sunbed use, age, sex and country/state of birth) previously identified as significant predictors of melanoma risk. These factors are included in both groups.

The setting is at the Princess Alexandra Hospital located in Brisbane, Queensland, Australia. Participants in this study represented various risk levels (low, moderate, and high risk) and range from 18 years old and up. Any participant who has previously provided a saliva sample for genetic analysis, and consented to be contacted for future research are eligible to be recruited to the present study.

Statistical methods / analysis
Basic descriptive statistics will be used to describe the sample and uptake of the intervention and control groups. Perceived control of melanoma risk and perceived risk relative to others will be summarised in figures and compared over time (baseline vs 1- vs 12-months), for different risk levels using Chi-square analysis. Changes in perceived risk of future melanoma and empowerment (GOS) will be assessed both between risk levels and across time points using mixed linear modelling. Differences in genetic testing related distress, uncertainty, and positive experiences (MICRA) will be evaluated using paired t-test at 1- vs 12-months. Data from the Personal Utility Scale will be summarised using basic descriptive statistics and will be evaluated for differences between risk levels using unpaired t-tests. For all statistical analyses, significance will be inferred at p=0.05.
Qualitative analysis
Thematic analysis will be conducted using the grounded theory approach described by Braun and Clarke (2006). This iterative process involves systematically identifying, comparing, and coding themes within and across interviews and accounts for deviant cases. Patterns and relationships between the codes will be used to develop second-order categories. The qualitative analysis software NVivo 11 will be used throughout data analysis to organize data into semantic themes (codes) and latent themes (themes). Initial coding and re-coding will be conducted by the research team. Any discrepancies in coding and overarching themes will be discussed and consolidated by researchers.
