A Model of Social Media Effects in Public Health Communication Campaigns: Systematic Review.

Background: Social media platforms are frequently used in health communication campaigns. Common understandings of campaign effects posit a sequential and linear series of steps from exposure to behavior change, commonly known as the hierarchy of effects model (HOE). These concepts need to be reevaluated in the age of social media, which are interactional and communal.

Skin cancer-related conditions managed in general practice in Australia, 2000-2016: a nationally representative, cross-sectional survey.

Objective: Skin cancer is Australia's most common and costly cancer. We examined the frequency of Australian general practice consultations for skin cancer-related conditions, by patient and general practitioner (GP) characteristics and by time period.

Design: Nationally representative, cross-sectional survey of general practice clinical activity.

Effect of an interactive educational activity using handheld ultraviolet radiation dosimeters on sun protection knowledge among Australian primary school students.

Ultraviolet radiation (UV) is the main cause of skin cancer, and children are a priority group for reducing UV exposure. We evaluated whether an interactive educational activity using handheld dosimeters improved UV-related knowledge among primary (elementary) school students. We conducted an uncontrolled before-after study among 427 students in grades 3-6 (ages 8-12 years) at five schools in the Greater Sydney region, Australia.

Impact of personal genomic risk information on melanoma prevention behaviors and psychological outcomes: a randomized controlled trial.

Purpose: We evaluated the impact of personal melanoma genomic risk information on sun-related behaviors and psychological outcomes.

Methods: In this parallel group, open, randomized controlled trial, 1,025 Australians of European ancestry without melanoma and aged 18-69 years were recruited via the Medicare database (3% consent). Participants were randomized to the intervention (n = 513; saliva sample for genetic testing, personalized melanoma risk booklet based on a 40-variant polygenic risk score, telephone-based genetic counseling, educational booklet) or control (n = 512; educational booklet).

School-based interventions to improve sun-safe knowledge, attitudes and behaviors in childhood and adolescence: A systematic review.

Ultraviolet radiation exposure is the leading cause of skin cancer, and childhood and adolescence is a particularly susceptible life period for exposure. This systematic review assessed whether interventions in elementary and secondary school settings reduced sun exposure, sunburns, and development of melanocytic nevi, and improved sun-safe knowledge, attitudes and sun protection behaviors in childhood and adolescence. A systematic search up to June 2020 of MEDLINE, Embase, CINAHL, Cochrane and ProQuest databases was undertaken, for studies conducted among students in an elementary or secondary school setting that compared an intervention group with a pre-intervention or separate control group.

Prevalence of skin examination behaviours among Australians over time.

Background: We aimed to examine the prevalence and correlates of opportunistic skin check behaviours among Australians and whether changes over time might explain increasing underlying rates of melanoma in situ.

Methods: The National Sun Protection Survey involved periodic telephone-based cross-sectional surveys during summer since 2003. Skin checks by a doctor in the past 12 months was asked in four summers over 2006-2017, and responses from 23,374 Australians aged 12-69 years were analysed.

Implementation considerations for offering personal genomic risk information to the public: a qualitative study.

Background: Genomic risk information, based on common genomic susceptibility variants associated with risk of complex diseases such as cancer, may be incorporated into personalised prevention and screening strategies. We aimed to engage with members of the public, who are important stakeholders in this process, to further inform program development and other implementation outcomes such as acceptability and appropriateness.

Methods: Semi-structured interviews were undertaken with 30 participants (aged 24-69 years, 50% female) recruited from a pilot trial in which they received personalised genomic risk information for melanoma.

'There is a lot of good in knowing, but there is also a lot of downs': public views on ethical considerations in population genomic screening.

Publics are key stakeholders in population genomic screening and their perspectives on ethical considerations are relevant to programme design and policy making. Using semi-structured interviews, we explored social views and attitudes towards possible future provision of personalised genomic risk information to populations to inform prevention and/or early detection of relevant conditions. Participants were members of the public (n=30) who had received information on their personal genomic risk of melanoma as part of a research project.
