Efficacy of an appearance-based and a health-based sun protection intervention on summer vacationers' behaviours, PRISME cluster randomized crossover trial, France.

OBJECTIVES: Sun-seeking vacationers are particularly vulnerable to melanoma. Appearance-based interventions (ABi) showing skin damage of ultraviolet exposure may be a promising prevention tool to improve skin protection. This study aimed to measure and compare the efficacy of an ABi and a health-based intervention (HBi) on French summer vacationers' behaviours and to identify differences between subpopulations. DESIGN: A cluster randomized crossover trial with three intervention groups (control, ABi, HBi) was conducted in eight campsites on the French Mediterranean coast in summer 2019. METHODS: 1355 vacationers of both sexes and aged 12-55 years were included and followed up after 4 days (T1) and 14 months (T2). Efficacy of interventions was evaluated using multilevel mixed-effect models comparing groups on three outcomes: self-reported sun protection behaviours, sunbathing and skin colour measures. Protection behaviours were analysed according to subpopulations. RESULTS: Compared to controls, the ABi group had a higher protection and sunbathed for fewer hours at T1 and T2. In the HBi group, the skin colour was lighter than controls at T1. When comparing ABi to HBi, ABi participants had lower exposure than HBi at T1 and T2. The protection of people with a 3-years university degree was higher in the HBi group than in others groups while that of people with a secondary school certificate was higher in the ABi group. CONCLUSIONS: Our study provides further evidence of individual sun protection interventions effect in a touristic setting and highlights the relevance of ABi messages to supplement HBi messages, particularly in certain subpopulations with low to intermediate education levels.

Novel sunprotection interventions to prevent skin cancer: A randomized study targeting Danes going on vacation to destinations with high UV index.

BACKGROUND: In Denmark, 16,500 cases of melanoma and keratinocyte cancers were registered in 2015, of which 90% could have been avoided by behavioral changes. We aimed to test novel interventions in a randomized design. The interventions targeted Danes going on vacation to high UVI destinations aiming to decrease sunburn by increasing use of sun protection to prevent skin cancer in the Danish population. METHODS: We report a randomized behavioral intervention during May-Dec 2018 with 1548 Danish adults on vacation in 2018 for a period of 1-3 weeks. The study population was population-based and aged 18-65 years. We tested two protection routines against minimal intervention control group (2-by2-factorial design): 1) Avoidance of the sun during peak hours and shade, use of the UV-index and planning of indoor/outdoor activity respectively and, 2) Coverage by increasing use of the hat advice and increasing sunscreen amount by application routine. Outcome was use of protection and sunburn. RESULTS: There were no differences in sunburn prevalence between intervention and control groups. Protection routine 1 and 2 both increased the overall protection score compared to non-users. Protection routine 1 increased the reported use of shade and decreased time exposed in the sun. Protection routine 2 increased the use of hat and sunscreen amount. CONCLUSION: Simple measures can help avoid the majority of one of the most widespread cancers worldwide. Vacations to high UVI destinations is a major influence on the annual Danish UV-exposure. We influenced travelers to protect themselves better and to increase sun protection behavior.

School-Level Factors Associated with Sun Protection Practices in California Elementary Schools.

BACKGROUND: This study examined implementation of district sun safety policy in schools and tested correlates of implementation in California public school districts. METHODS: Principals (N = 118) and teachers (N = 113) in California public elementary schools (N = 118) were recruited and completed a survey on sun protection policies and practices. The sample contained schools whose districts subscribed to the California School Boards Association and adopted Board Policy 5141.7 for sun safety. Principals and teachers reported on implementation of 10 school practices related to BP 5141.7 indicating which practices were implemented in the school. RESULTS: Years in public education (Exponentiated Score (ES) = 0.51, p < .001), years worked in the current district (ES = 0.49, p < .001), perception that parents should take action to protect children from the sun (ES = 0.43, p < .01), and personal skin phenotype (Low Risk ES = 0.55; High Risk ES = 0.09, p < .05) were associated with number of practices implemented in the school using multiple Poisson regression. CONCLUSIONS: Policy implementation is more likely among schools with experienced faculty, when parents are seen as important partners in student skin cancer prevention, and when school principals and teachers have a lower personal risk phenotype.

Using Social Media to Determine the Affective and Cognitive Components of Tweets about Sunburn.

BACKGROUND: The relationship between social media usage and the public's expressions of sunburn remains unexplored. This study is a content analysis of Twitter that was performed to identify the public's expressions, perceptions, and attitudes towards sunburn. METHODS: Qualitative content analysis was conducted on tweets by Australian Twitter users during January 2007 and January 2016. Out of 2,000 tweets available, in-depth content analysis of 200 random tweets was performed. RESULTS: Tweets in this study were categorised into 10 distinct themes, three of which were cognitive (fact based) and seven affective (emotional), while one was miscellaneous. Results reveal that tweets about sunburn overwhelmingly contained affective as opposed to cognitive components. In addition, the sentiments contained in the affective tweets were frequently positively (68.9%) rather than negatively valanced (31.1%). While humour was the most common theme (n = 68 tweets), many tweets also expressed a link between Australian national identity and sunburn (n = 25 tweets). CONCLUSION: Many of the tweets analysed contained positive affective sentiments such as joy, rather than worry or concern, suggesting an avenue for further health promotion research.

A pilot study of a telehealth family-focused melanoma preventive intervention for children with a family history of melanoma.

OBJECTIVE: Melanoma preventive interventions for children with familial risk are critically needed because ultraviolet radiation (UVR) exposure and sunburn occurrence early in life are the primary modifiable risk factors for melanoma. The current study examined the feasibility and acceptability of a new, family-focused telehealth intervention for children with familial risk for melanoma and their parents. The study also explored changes in child sun protection and risk behaviors, sunburn occurrence, and objectively measured UVR exposure. METHODS: This was a prospective study with a single-group design (n = 21 parent-child dyads, children ages 8-17). Dyads were asked to participate in three in-person assessments and three live video teleconference intervention sessions. RESULTS: The intervention was feasibly delivered, and the intervention content was acceptable to parents and children. The intervention was associated with improvements in child use of certain sun protection strategies over time and declines in child UVR exposure. CONCLUSIONS: A telehealth-delivered,family-focused melanoma preventive intervention was feasibly delivered and was acceptable to parent-child dyads. Future melanoma preventive interventions for this at-risk population could incorporate eHealth technologies to facilitate improvements in use of sun protection and monitoring of UVR exposure. This trial was registered with Clinicaltrials.gov, number NCT02846714.

Risk Perception Plays Minimal Role in Sun Exposure Behaviours.

Despite decades of public health campaigns, tanning and sunburn still occur at unacceptably high rates. Skin cancer prevention campaigns predominately focus on increasing awareness of the risk of excessive sun exposure. This study sought to assess the efficacy of this approach, by interrogating correlations between risk perception and sun exposure behaviour. A 31-item questionnaire assessing skin cancer risk factors, tanning attitudes, sunburn and tanning behaviour was undertaken by individuals who attended a workplace skin check. Validated questions were included to assess cognitive and affective risk perception and to frame risk as absolute, comparative and conditional. One hundred sixty-seven respondents completed the questionnaire. No aspects of risk perception (absolute cognitive, affective or conditional) significantly correlated with protective sun exposure behaviour, with the exception of perceived comparative severity of skin cancer. Instead, positive tanning attitudes were far more significantly correlated with sun exposure behaviour. Actual risk and risk perception have very limited impact on sun exposure behaviour. Instead, sun exposure behaviour was significantly linked with positive tanning attitudes. It is suggested, therefore, that campaigns focussing solely on education regarding risk factors appear to have been ineffective in behaviour mitigation, and innovative approaches, aimed at influencing tanning norms, might complement the existing educational campaigns.

Sun Protection Habits and Sunburn in Elite Aquatics Athletes: Surfers, Windsurfers and Olympic Sailors.

The objective of this study was to analyse the sun exposure habits of elite aquatics athletes, together with their sunburn history and skin examination habits, taking into account differences by sex and between sports. A cross-sectional health survey was conducted at world championship events during which elite surfers, windsurfers and Olympic sailors from 30 different countries were invited to participate. The athletes were asked to complete a self-administered questionnaire focused on sun protection habits, sun exposure and sports practices. The survey was completed by 240 athletes, 171 men (71.3%) and 69 women (28.8%), with a mean age of 22 years (SD 5.86) and skin phototypes I (6.3%), II (3.3%), III (22.0%), IV (32.5%), V (9.2%) and VI (1.7%). There were significant differences between male and female athletes in skin self-examination (p < 0.001) and in the use of sunglasses (p < 0.001). In sunburn history during the last season, there were significant differences (p < 0.001) among the three sports analysed, in both sexes. The mean rate of sunburn during the previous season was 76.7%, and 27.5% of participants reported having experienced three or more sunburns that lasted at least 1 day. This type of athlete is at high risk of sunburn and hence of future skin cancer. However, there is a general lack of awareness of this risk. This study highlights the need to inform such athletes and to raise awareness of the dangers, through educational interventions on the importance of protecting against sunburn in order to reduce the future incidence of skin cancer.

Primary Language in Relation to Knowledge of Diagnosis and Sun-Related Behaviors in Adults with Sun-Exacerbated Dermatoses.

OBJECTIVE: To evaluate how patients' primary spoken language influences the understanding of their disorder and their subsequent sun-related behaviors. METHODS: This was a cross-sectional study conducted between February 2015 and July 2016 in two outpatient dermatology clinics among 419 adults with a sun-exacerbated dermatosis. The primary outcome was a successful match between the patient-reported diagnosis on a survey and the dermatologist-determined diagnosis. RESULTS: Of participants, 42% were native English speakers, and 68% did not know their diagnosis. Fewer non-native English speakers identified one risk factor for their condition (46% versus 54%, p < 0.01). A greater number of non-native English speakers were less familiar with medical terminology. Native English speakers were 2.5 times more likely to know their diagnosis compared to non-native speakers (adjusted odds (aOR) 2.5, 95% confidence interval, 1.32 to 4.5; p = 0.005). Additional factors associated with higher odds of knowing the diagnosis included: Higher education, sunscreen use, female gender, symptoms for 1-5 years, and diagnosis of melasma and postinflammatory hyperpigmentation (PIH). CONCLUSIONS: Knowledge of the diagnosis and understanding of factors that may influence skin disease may promote conscious sun behavior. Patients who knew that their diagnosis was sun-exacerbated had higher odds of wearing sunscreen.

Association of Skin Cancer Risk and Protective Behaviors with Health Literacy Among Young Adults in the USA.

BACKGROUND: The goal of this study was to investigate the association of health literacy with skin cancer risk and protective behaviors among young adults at moderate to high risk of skin cancer, the most common cancer. METHOD: A US national sample of 958 adults, 18-25 years old, at moderate to high risk of developing skin cancer, completed a survey online. Behavioral outcomes were ultraviolet (UV) radiation exposure (e.g., indoor and outdoor tanning, sunburn) and protective (e.g., sunscreen use, sunless tanning) behaviors. Multivariable regression analyses were conducted to determine whether health literacy (a four-item self-report measure assessing health-related reading, understanding, and writing) was associated with behavioral outcomes while controlling for demographic factors. RESULTS: Higher health literacy was independently associated with less sunbathing, odds ratio (OR) = 0.77, 95% confidence interval (CI) = 0.60-0.98; less indoor tanning, OR = 0.38, CI = 0.31-0.48; and less use of tanning oils, OR = 0.54, CI = 0.43-0.69. However, health literacy was also associated with a lower likelihood of wearing long pants, OR = 0.76, CI = 0.58-0.99, or a hat, OR = 0.68, CI = 0.53-0.87, when outdoors. On the other hand, higher health literacy was associated with higher incidental UV exposure, OR = 1.69, CI = 1.34-2.14, and a greater likelihood of ever having engaged in sunless tanning, OR = 1.50, CI = 1.17-1.92. CONCLUSION: Interestingly, higher health literacy was associated with lower levels of intentional tanning yet also higher incidental UV exposure and lower skin protection among US young adults. These findings suggest that interventions may be needed for young adults at varying levels of health literacy as well as populations (e.g., outdoor workers, outdoor athletes/exercisers) who may be receiving large amounts of unprotected incidental UV.

Beliefs, attitudes and perceptions to sun-tanning behaviour in the Norwegian population: a cross-sectional study using the health belief model.

BACKGROUND: Norway has one of the highest incidences of melanoma in the world. It has been suggested that the majority of all skin cancers could be prevented by changes related to sun-tanning behaviour. This study explores the sun-tanning behaviour of the Norwegian population using a modified Health Belief Model (HBM). Increased knowledge about beliefs, attitudes and sun-tanning behaviour can provide information which may be useful for future sun protection interventions. METHODS: In 2017, 1004 members of the Norwegian population completed cross-sectional online surveys. People who seek the sun for tanning purposes was the eligibility criterion for this study, reducing the study population to 569. With the aid of the constructs from the HBM, predictive factors explaining sun-tanning behaviour were determined using multivariate linear regression adjusted for demographics (gender, age, education and income). Furthermore, the predictor variables, empowerment and benefits of tanning, were added to the model. RESULTS: Five of the constructs in the modified HBM showed significant correlation with sun-tanning behaviour using bivariate analysis. The strongest correlation was perceived barriers of sun protection (0.42), with the next strongest being the benefits of tanning (0.30). The modified model explained 31% of the variation in sun-tanning behaviour using multivariate analysis. Significant predictors from the HBM to sun-tanning behaviour were perceived barriers to sun protection (Beta = 0.36, p < 0.001) and the severity of melanoma (Beta = - 0.20, p < 0.001). In addition, empowerment (Beta = 0.05, p = 0.05) and the benefits of tanning (Beta = 0.28, p < 0.001) proved to be variables with significant effect on sun-tanning behaviour. The demographic factors age, education and income were also associated with sun-tanning behaviour (p < 0.05). CONCLUSION: Based on the results of this study, several factors in the modified HBM had a significant impact on Norwegians' sun-tanning behaviour. The results indicate that future sun protection interventions should focus on reducing barriers in relation to sun protection behaviour, as well as emphasizing the severity of adverse tanning behaviour and melanoma. Efforts to alter the perceptions of the beneficial factors of tanning behaviour can also be appropriate in health promotion campaigns and interventions. Finally, implementing empowerment strategies could have a positive effect on promoting healthy sun-tanning behaviour.

Sun protection and young female beachgoers: A formative theory-based approach to identifying key sun safe beliefs.

ISSUE ADDRESSED: The prevalence of skin cancer remains at a high level in Australia. Young female Australian beachgoers are an at-risk population of skin cancer. Research on sun-protective beliefs held by this at-risk group is limited. METHODS: Based on the Theory of Planned Behaviour (TPB), we conducted a formative study to understand key sun safe messages among young female beachgoers in Queensland, including an elicitation study (Phase 1; N = 21, Mage  = 24.30 years) and a two-wave questionnaire survey (Phase 2; N = 140, Mage  = 23.96 years). RESULTS: Following content analysis and regression analyses, three key beliefs were identified: "be uncomfortable and/or unstylish" (behavioural belief), "friends and peers" (normative belief) and "lack of motivation to reapply sunscreen" (control belief). CONCLUSIONS: The results highlight the influences of friends and peers on beachgoers' sun-protective behaviour for this young female adult cohort. Compared to previous findings among the general population, discrepancies in beliefs suggest interventions targeting this cohort should specifically focus on fashionable sun safe images and motivation to reapply sunscreen. SO WHAT?: Future health promotion and public education should utilise various strategies according to specific groups given the discrepancies identified in beliefs. For female beachgoers, sun safe images and motivations should be the primary foci.

Public Health Implications of Google Searches for Sunscreen, Sunburn, Skin Cancer, and Melanoma in the United States.

PURPOSE: Google Trends (GT) offers insights into public interests and behaviors and holds potential for guiding public health campaigns. We evaluated trends in US searches for sunscreen, sunburn, skin cancer, and melanoma and their relationships with melanoma outcomes. DESIGN: Google Trends was queried for US search volumes from 2004 to 2017. Time-matched search term data were correlated with melanoma outcomes data from Surveillance Epidemiology and End Results Program and United States Cancer Statistics databases (2004-2014 and 2010-2014, respectively). SETTING: Users of the Google search engine in the United States. PARTICIPANTS: Google search engine users in the United States. This represents approximately 65% of the population. MEASURES: Search volumes, melanoma outcomes. ANALYSIS: Pearson correlations between search term volumes, time, and national melanoma outcomes. Spearman correlations between state-level search data and melanoma outcomes. RESULTS: The terms "sunscreen," "sunburn," "skin cancer," and "melanoma" were all highly correlated ( P < .001), with sunscreen and sunburn having the greatest correlation ( r = 0.95). Sunscreen/sunburn searches have increased over time, but skin cancer/melanoma searches have decreased ( P < .05). Nationally, sunscreen, sunburn, and skin cancer were significantly correlated with melanoma incidence. At the state level, only sunscreen and melanoma searches were significantly correlated with melanoma incidence. CONCLUSIONS: We conclude that online skin cancer prevention campaigns should focus on the search terms "sunburn" and "sunscreen," given the decreasing online searches for skin cancer and melanoma. This is reinforced by the finding that sunscreen searches are higher in areas with higher melanoma incidence.

Uplifting Fear Appeals: Considering the Role of Hope in Fear-Based Persuasive Messages.

Fear appeal research has focused, understandably, on fear as the primary emotion motivating attitude and behavior change. However, while the threat component of fear appeals associates with fear responses, a fear appeals' efficacy component likely associates with a different emotional experience: hope. Drawing from appraisal theories of emotion in particular, this article theorizes about the role of hope in fear appeals, testing hypotheses with two existing data sets collected within the context of sun safety messages. In both studies, significant interactions between hope and self-efficacy emerged to predict behavioral intentions. Notable main effects for hope also emerged, though with less consistency. Further, these effects persisted despite controlling for the four cognitions typically considered central to fear appeal effectiveness. These results, consistent across two samples, support the claim that feelings of hope in response to fear appeals contribute to their persuasive success. Implications for developing a recursive model of fear appeal processing are discussed.

Level of Education and Knowledge of Skin Cancer Risk Factors in Patients Undergoing Maintenance Hemodialysis.

INTRODUCTION: An increased risk of skin cancer is particularly important in patients undergoing maintenance hemodialysis (HD), who are potential transplant recipients. In transplant recipients who are exposed to immunosuppressive therapy, neoplastic skin disease my take a more aggressive course. Increased exposure to photoradiation, elderly age, a low skin phototype, sunburn during childhood, and a history of smoking are the main factors contributing to the development of skin neoplasms. Knowledge of these risk factors as well as education on sun protection should be important for such patients. PATIENTS AND METHODS: We studied 105 HD patients (57 men, 48 women) with a mean age of 60.8 (range 25-94) years. Knowledge of skin cancer risk factors was assessed on the basis of a questionnaire regarding skin cancer risk factors. RESULTS: In the study group, 23.8% of patients claimed that they frequently and intensively engage in sunlight exposure. However, only 11.4% have started to apply sunblockers recently. Sunburn during adolescence was reported by 12.4% patients. Among the patients studied, 65.7% had skin phototype I or II, and only 34.3% had phototype III. In the investigated study group, 55.2% admitted smoking: 30.5% smoked more than 20 pack-years. Among the patients studied only 2.86% could name 3 skin cancer risk factors, 29.5% 2 risk factors, 60% 1 risk factor, and 7.6% could not name any risk factor. CONCLUSIONS: The results presented prove that patients undergoing HD lack knowledge regarding skin cancer risk factors, which explains the necessity of education, particularly on the dangers of sun radiation.

"We Don't Really Do Anything Unless it's Really Bad": Understanding Adolescent Sun Protective Knowledge, Attitudes and Behaviors in the U.S.

Risk factors for melanoma, the deadliest form of skin cancer, include lifetime sun exposure and a history of sunburns. However, a minority of adolescents report consistent engagement in sun protective behaviors. The few sun protection interventions that have targeted adolescents have had little effect on behavior change, which suggests that a better understanding of the issue, especially from the adolescents' perspective, is needed. Although efforts to qualitatively examine adolescent sun protection have been carried out in a handful of countries, no studies to date have focused on U.S. adolescents. We conducted focus groups with 44 6th-8th grade students in Colorado to explore their sun protection knowledge, attitudes and behaviors. Results supported previous findings that adolescents do not engage in regular skin protection but have experienced the negative consequences of sun exposure (e.g., severe sun burns, and blistering). In addition, participants demonstrated limited and sometimes inaccurate knowledge about the long-term risks of sun exposure, as well as effective methods of sun protection. Barriers to engaging in sun protective behaviors included a desire to tan, inconvenience, and physical discomfort. Facilitators included peer and family encouragement, previous experience with sunburns and/or skin cancer, and knowledge of potential consequences. These findings provide valuable insights that can inform future intervention and research related to sun protection among U.S. adolescents.

Knowledge deficit, attitude and behavior scales association to objective measures of sun exposure and sunburn in a Danish population based sample.

The objective of this study was to develop new scales measuring knowledge and attitude about UVR and sun related behavior, and to examine their association to sun related behavior objectively measured by personal dosimetry. During May-August 2013, 664 Danes wore a personal electronic UV-dosimeter for one week that measured their UVR exposure. Afterwards, they answered a questionnaire on sun-related items. We applied descriptive analysis, linear and logistic regression analysis to evaluate the associations between the questionnaire scales and objective UVR measures. Perceiving protection as routine and important were positively correlated with protective behavior. Knowledge deficit of UV and risk of melanoma, perceived benefits and importance of protection behavior was also correlated with use of protection. 'Knowledge deficit of UV and risk of melanoma and Perceived barrier towards sun avoidance between 12 and 15' were both associated with increased risk of sunburn. Attitude towards tan was associated to both outdoor time and exposure as well as use of protection, but not to sunburn. The results regarding Knowledge deficit of UV and risk of melanoma associated to UVR exposure and Perceived barrier towards sun avoidance between 12 and 15 emphasize the importance of awareness of melanoma risk and the priority of the skin cancer prevention advice. Shifting activities to outside the suns peak-hours could be an approach for structural and campaign preventive measures. Knowledge of items predicting exposure to UVR, use of protection and sunburn are important for planning of preventive interventions and melanoma research.

Correlates of sun protection behaviors among Hispanic children residing in a high UVR environment.

BACKGROUND/PURPOSE: Rates of melanoma are rising in Hispanics in the United States. Excessive sun exposure in childhood increases the risk of melanoma in adulthood, and little is known about the factors motivating sun protection behaviors among Hispanic youth. METHODS: Correlates of sun protection were examined among Hispanic children residing in Los Angeles, California (N = 1891). Associations between multiple constructs (psychosocial, familial, and cultural) and sun protection outcomes (use of sunscreen, protective clothing, and shade seeking/sun avoidance) were examined. RESULTS: Family variables were associated with more frequent sun protection among Hispanic children across outcomes, as were perceived peer norms, perceived self-efficacy, and fewer sun protection barriers. Skin cancer risk factors such as lighter skin and sunburn experience, and level of acculturation were not associated with greater sun protection. CONCLUSION: Family sun protection habits are instrumental to Hispanic children's sun safe behaviors, and interventions that engage the family may be most effective. Increasing risk communication to high-risk subgroups of Hispanic children (those with lighter, more sun reactive skin) is important when developing intervention strategies. However, there is overlap between Hispanic children's sun protection correlates and those observed among non-Hispanic white children, suggesting that interventions to improve sun protection may generalize across cultural contexts.

Predictors of sun protection behaviours and sunburn among Australian adolescents.

BACKGROUND: Excessive sun exposure and sunburn increase individuals' risk of skin cancer. It is especially important to prevent sunburn in childhood due to the higher relative risk of skin cancer across the life span compared to risk associated with sunburn episodes experienced later in life. This study examined demographic and attitudinal factors associated with engagement in a range of sun protection behaviours (wearing a hat, wearing protective clothing, staying in the shade, and staying indoors during the middle of the day) and the frequency of sunburn among Western Australian adolescents to provide insights of relevance for future sun protection campaigns. METHODS: Cross-sectional telephone surveys were conducted annually with Western Australians between 2005/06 and 2014/15. The results from 4150 adolescents aged 14-17 years were used to conduct a path analysis of factors predicting various sun protection behaviours and sunburn. RESULTS: Significant primary predictors of the sun protection behaviours included in the study were skin type (sun sensitivity), gender, tanning-related attitudes and behaviours, and perceived relevance of public service advertisements that advocate sun protection. Of the four sun protection behaviours investigated, staying in the shade and staying indoors during the middle of the day were associated with a lower frequency of sunburn. CONCLUSION: There is a particular need to target sun protection messages at adolescent males who are less likely to engage in the most effective sun protection behaviours and demonstrate an increased propensity to experience sunburn. The results suggest that such future sun protection messages should include a focus on the importance of staying in the shade or indoors during periods of high UV radiation to increase awareness of the efficacy of these methods of avoiding skin cancer.

Baseline Predictors of Singular Action Among Participants With Multiple Health Behavior Risks.

PURPOSE: Previous studies found that treatment effects can change two behaviors, but not one. This study examined baseline transtheoretical model constructs as three alternative predictors (stage of change, effort, and severity) of singular action among participants with co-occurring health behavior risks. DESIGN: The study examined participants at risk for three pairs of behaviors (sun and smoking; smoking and diet; and diet and sun). Analyses were conducted with participants who changed only one behavior in a pair (singular action). SETTING: School and home-based behavior change programs recruited participants via schools, worksites, and physician practices. School, worksite, medical, and home-based prevention programs were the study setting. SUBJECTS: The sample (N = 3213) was age 44.6 years (SD, 11.1 years), 94.6% white, and 63.7% female. MEASURES: Stages of change, effort, and severity variables were measured. ANALYSIS: Pooled data were analyzed using logistic regressions from three randomized controlled trials. RESULTS: Across all three behaviors, stage of change, effort, and severity effects were consistently related to behavior change at 24 months. Change efforts on one behavior were related to change on another behavior. Baseline sun severity (odds ratio, .97 [.94, 1.00]; p = .046) and smoking severity (odds ratio, .89 [.80, .98]; p = .019) were significant predictors of change on diet at final follow-up. CONCLUSION: Stage of change was the biggest predictor. Problem severity was the smallest predictor of change at 2-year follow-up. Four of six predictors were within behaviors, whereas two were between.

Relationship factors and couples' engagement in sun protection.

Individuals may be more motivated to adopt health practices if they consider the benefits of these behaviors for their close relationships. The goal of this study was to examine couple concordance with sun protection and use the interdependence and communal coping theory to evaluate the role of relationship factors in sun protection. One hundred and eighty-four married couples aged 50 years and older completed measures of objective skin cancer risk, perceived risk, sun protection benefits, relationship-centered motivations for sun protection, discussions about sun protection, and sun protection. A mediational model was evaluated. Results indicated a high level of couple concordance. Partners who adopted a relationship-centered motivation for sun protection were more likely to discuss sun protection with one another, and partners who discussed sun protection together were more likely to engage in sun protection. One partner's attitude about personal risk and sun protection benefits was associated with the other partner's sun protection. Wives had higher relationship-centered motivation and discussed sun protection more with their husbands. Behavioral interventions may benefit from encouraging couples to discuss sun protection and encouraging married individuals to consider the benefits of sun protection for their relationship and for their spouse's health.
