An online skin cancer risk-reduction intervention for young adults: Mechanisms of effects.

ABSTRACT: OBJECTIVE:The study's purpose was to investigate moderator, implementation, and mediator variables related to the efficacy of UV4.me, an Internet intervention that decreased ultraviolet radiation (UV) exposure and increased skin protection behaviors among young adults. METHOD:A total of 965 18-25 year olds at risk for skin cancer were recruited nationally online. Participants were randomized to an experimental website (UV4.me), a control website, or assessment only. Participant characteristics (moderators), engagement with and perceptions of interventions (implementation measures), and exposure and protection attitudinal variables (mediators) were assessed. Linear regression and mediation analyses were conducted. RESULTS:Intervention effects on skin protection were greater for participants with a family history of skin cancer (p = .01). Intervention effects on UV exposure were greater among recent indoor tanners (p = .04). Improvements in skin protection (but not UV exposure) were associated with perceiving the interventions as satisfying or helpful (ps < .01). The experimental group had better outcomes if they completed more modules (ps < .01) or set more behavioral goals (ps < .01). Knowledge and exposure decisional balance mediated intervention effects for UV exposure (ps < .05), and protection decisional balance, self-efficacy, and intentions mediated intervention effects for protection (ps < .05). CONCLUSIONS:The experimental intervention was more efficacious for certain high risk groups. The more individuals liked and engaged with the interventions (e.g., by setting goals), the better their outcomes. Mediation results inform theory about change mechanisms and differed by behavioral outcome. (PsycINFO Database Record

Project description:Skin cancer is the most common cancer, and its incidence is increasing. Young adults expose themselves to large amounts of ultraviolet radiation (UV) and engage in minimal skin protection, which increases their risk. Internet interventions are effective in modifying health behaviors and are highly disseminable. The current study's purpose was to test an Internet intervention to decrease UV exposure and increase skin protection behavior among young adults.RCT conducted in 2014, with data analyzed in 2015.A national sample of adults aged 18-25 years at moderate to high risk of developing skin cancer by a self-report measure was recruited online.Participants were randomized to one of three intervention conditions: assessment only, the website of a skin cancer organization, or a tailored interactive multimedia Internet intervention program (UV4.me) based on the Integrative Model of Behavioral Prediction.Self-reported overall UV exposure and skin protection assessed at 3 and 12 weeks after baseline. Secondary outcomes were self-reported intentional and incidental UV exposure, sunburns, sunscreen use, and skin cancer screening.For the intervention arm, there were significant decreases in UV exposure and increases in skin protection at both follow-up time points compared with the assessment-only condition (p<0.001). The effect sizes (Cohen's d) comparing the experimental and assessment-only arm for exposure behaviors were 0.41 at 3-week follow-up and 0.43 at 12-week follow-up. The effect sizes for protection behaviors were 0.41 at 3-week follow-up and 0.53 at 12-week follow-up. The control condition was not significantly different from the assessment only condition. All three conditions exhibited decreased exposure and increased protection at both follow-ups (p<0.01), but the effect was much stronger in the intervention group. Secondary outcomes were generally also significantly improved in the intervention condition compared with the other conditions.This is the first published report describing the results of an RCT of an Internet intervention to modify skin cancer risk behaviors among young adults. The UV4.me intervention significantly improved self-reported skin cancer prevention behaviors. Future research will investigate mechanisms of change and approaches for dissemination.This study is registered at www.clinicaltrials.gov NCT02147080.

Project description:BACKGROUND:Many cancers are preventable through lifestyle modification; however, few adults engage in behaviors that are in line with cancer prevention guidelines. This may be partly due to the mixed messages on effective cancer prevention strategies in popular media. The goal of the McMaster Optimal Aging Portal (the Portal) is to increase access to trustworthy health information. The purpose of this study was to explore if and how knowledge translation strategies to disseminate cancer prevention evidence using the Portal influence participants' knowledge, intentions and health behaviors related to cancer risk. METHODS:Adults ≥40 years old, with no cancer history were randomized to a 12-week intervention (weekly emails and social media posts) or control group. Quantitative data on knowledge, intentions and behaviors (physical activity, diet, alcohol consumption and use of tobacco products) were collected at baseline, end of study and 3 months later. Participant engagement was assessed using Google Analytics, and participant satisfaction through open-ended survey questions and semi-structured interviews. RESULTS:Participants (n = 557, mean age 64.9) were predominantly retired (72%) females (81%). Knowledge of cancer prevention guidelines was higher in the intervention group at end of study only (+ 0.3, p = 0.01). Intentions to follow cancer prevention guidelines increased in both groups, with no between-group differences. Intervention participants reported greater light-intensity physical activity at end of study (+ 0.7 vs. 0.1, p = 0.03), and reduced alcohol intake at follow u (- 0.2 vs. + 0.3, p < 0.05), but no other between-group differences were found. Overall satisfaction with the Portal and intervention materials was high. CONCLUSIONS:Dissemination of evidence-based cancer prevention information through the Portal results in small increases in knowledge of risk-reduction strategies and with little to no impact on self-reported health behaviours, except in particular groups. Further tailoring of knowledge translation strategies may be needed to see more meaningful change in knowledge and health behaviours.

Project description:BackgroundSkin cancer is the most prevalent and most preventable cancer in Australia. Despite Australia's long-running public health campaigns, young Australian adults continue to report high levels of ultraviolet radiation (UVR) exposure and frequent sunburns. Young people are now increasingly turning away from traditional media, such as newspapers and TV, favoring Web-based streaming, which is challenging the health care sector to develop new ways to reach this group with targeted, personalized health promotion messages. Advances in technology have enabled delivery of time- and context-relevant health interventions.ObjectiveThe primary aim of this randomized controlled trial was to test the effect of UVR feedback from a smartphone app or a UVR dosimeter feedback device on sun protection habits, sun exposure behaviors, sunburn, and physical activity levels in young adults.MethodsYoung adults aged 18-35 years (n=124) were recruited from Queensland, Australia, between September 2015 and April 2016, via social or traditional media campaigns and outreach activities in the local community. Participants were randomized into 3 groups for a 4-week intervention: (1) no intervention control group; (2) UVR monitor group, who were asked to wear a UVR dosimeter feedback device set to their skin type; and (3) a SunSmart app group, who were asked to download and use the SunSmart phone app. Data were self-assessed through Web-based surveys at baseline and 1 week and 3 months postintervention.ResultsComplete data were available for 86.2% (107/124) of participants (control group, n=36; UVR monitor group, n=36; and SunSmart app group, n=35). Intervention uptake in the UVR monitor group was high, with 94% (34/36) of participants using the device all or some of the time when outdoors. All SunSmart app group participants downloaded the app on their smartphone. There was no significant difference in the change in the sun protection habits (SPH) index (main outcome measure) across the 3 groups. However, compared with the control group, a significantly greater proportion of the participants in the UVR monitor group reduced their time unprotected and exposed to UVR on weekends during the intervention compared with the baseline (odds ratio [OR]: 2.706, 95% CI 1.047-6.992, P=.04). This significant effect was sustained with greater reductions observed up to 3 months postintervention (OR: 3.130, 95% CI 1.196-8.190, P=.02). There were no significant differences between the groups in weekday sun exposure, sunscreen use, sunburn, suntan, or physical activity.ConclusionsUsing technology such as apps and personal UVR monitoring devices may improve some sun exposure behaviors among young adults, but as the SPH index did not increase in this study, further research is required to achieve consistent uptake of sun protection in young people.Trial registrationThe Australian and New Zealand Clinical Trials register ACTRN12615001296527; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=368458 (Archived by WebCite at http://www.webcitation.org/731somROx).

Project description:BackgroundPeople experiencing homelessness have higher rates of HIV than those who are stably housed. Mental health needs, substance use problems, and issues unique to homelessness such as lack of shelter and transiency need to be considered with regard to HIV prevention. To date, HIV prevention interventions for young adults experiencing homelessness have not specifically addressed modifiable real-time factors such as stress, sexual or drug use urge, or substance use, or been delivered at the time of heightened risk. Real-time, personalized HIV prevention messages may reduce HIV risk behaviors.ObjectiveThis pilot study tested the initial efficacy of an innovative, smartphone-based, just-in-time adaptive intervention that assessed predictors of HIV risk behaviors in real time and automatically provided behavioral feedback and goal attainment information.MethodsA randomized attention control design was used among young adults experiencing homelessness, aged 18-25 years, recruited from shelters and drop-in centers in May 2019. Participants were randomized to either a control or an intervention group. The intervention (called MY-RID [Motivating Youth to Reduce Infection and Disconnection]) consisted of brief messages delivered via smartphone over 6 weeks in response to preidentified predictors that were assessed using ecological momentary assessments. Bayesian hierarchical regression models were used to assess intervention effects on sexual activity, drug use, alcohol use, and their corresponding urges.ResultsParticipants (N=97) were predominantly youth (mean age 21.2, SD 2.1 years) who identified as heterosexual (n=51, 52%), male (n=56, 57%), and African American (n=56, 57%). Reports of sexual activity, drug use, alcohol use, stress, and all urges (ie, sexual, drug, alcohol) reduced over time in both groups. Daily drug use reduced by a factor of 13.8 times over 6 weeks in the intervention group relative to the control group (Multimedia Appendix 4). Lower urges for sex were found in the intervention group relative to the control group over the duration of the study. Finally, there was a statistically significant reduction in reports of feeling stressed the day before between the intervention and control conditions (P=.03).ConclusionsFindings indicate promising intervention effects on drug use, stress, and urges for sex in a hard-to-reach, high-risk population. The MY-RID intervention should be further tested in a larger randomized controlled trial to further investigate its efficacy and impact on sexual risk behaviors.Trial registrationClinicalTrials.gov NCT03911024; https://clinicaltrials.gov/ct2/show/NCT03911024.
