A Randomized Trial to Evaluate the Efficacy of a Web-Based HIV Behavioral Intervention for High-Risk African American Women.

The aim of this study was to develop and test a cost-effective, scalable HIV behavioral intervention for African American women. Eighty-three African American women were recruited from a community health center and randomly assigned to either the web-based Safe Sistah program or to a delayed HIV education control condition. The primary outcome was self-reported condom use. Secondary measures assessed other aspects of the gender-focused training included in Safe Sistah. Participants completed self-report assessments prior to randomization, 1- and 4-months after their program experience. Across the entire study period, women in the experimental condition significantly increased their condom use relative to controls (F = 5.126, p = 0.027). Significant effects were also found for sexual communication, sex refusal, condom use after alcohol consumption, and HIV prevention knowledge. These findings indicate that this web-based program could be an important component in reducing the HIV disparities among African American women.

Impact of melanoma genetic test reporting on perceived control over melanoma prevention.

To determine whether receiving melanoma genetic test results undermines perceived control over melanoma prevention, control-related beliefs were examined among 60 adults from melanoma-prone families receiving CDKN2A/p16 test results (27 unaffected noncarriers, 15 unaffected carriers, 18 affected carriers; response rate at 2 years = 64.9 % of eligible respondents). Multilevel modeling of perceived control ratings over a 2-year period revealed significant variation in individual trajectories: most participants showed increases (45 %) or no change (38.3 %), while 16.7 % showed decreases. At the group level, noncarriers reported sustained increases through the 2-year follow-up (ps < .05); unaffected carriers reported significant short-term increases (ps < .05); and affected carriers reported no change. Participants in all groups continued to rate photoprotection as highly effective in reducing melanoma risk and reported decreased beliefs that carrying the p16 mutation would inevitably lead to the development of melanoma. Qualitative responses immediately following counseling and test reporting corroborated these findings, as 93 % indicated it was possible to either prevent (64.9 %) or decrease the likelihood (28.1 %) of future melanomas. Thus, genetic test reporting does not generally undermine perceived control over melanoma prevention, though variability in response to positive results warrants future study.

A Web-based health promotion program for older workers: randomized controlled trial.

BACKGROUND: Recent evidence supports the efficacy of programs that promote improvements in the health practices of workers 50 years and older who are at higher risk for chronic diseases than younger workers are. Internet-based programs that promote healthy practices have also shown promise and, therefore, should be especially appropriate for workers aged 50 years and older. OBJECTIVE: The purpose of the research was to evaluate the effectiveness of HealthyPast50, a fully automated Web-based health promotion program based on social cognitive theory and aimed specifically at workers 50 years and older. METHODS: The randomized controlled trial was conducted across multiple US offices of a large global information technology company. The sample included 278 employees aged 50 to 68 who were recruited online and randomly assigned to the Web-based HealthyPast50 program or to a wait-list control condition. Self-report measures of diet, physical activity, stress, and tobacco use were collected online before and 3 months after the program group was given access to the program. Use data included number of log-ins and number of pages accessed. The primary analysis was multiple linear regression, following intent-to-treat principles with multiple imputation using the Markov chain Monte Carlo (MCMC) approach for nonmonotone missing data. Potential moderators from demographic characteristics and program dosage effects were assessed using multiple linear regression models. Additional analyses were conducted on complete (nonimputed) cases, excluding program participants who used the program for less than 30 minutes. RESULTS: Retention rates were good for both groups: 80.4% (111/138) for the program group and 94.3% (132/140) for the control group. Program group participants spent a mean of 102.26 minutes in the program (SD 148.32), logged in a mean of 4.33 times (SD 4.28), and viewed a mean of 11.04 pages (SD 20.08). In the analysis of the imputed dataset, the program group performed significantly better than the control group on diet behavioral change self-efficacy (estimated adjusted difference [Δ]=0.16, P=.048), planning healthy eating (Δ=0.17, P=.03), and mild exercise (Δ=1.03, P=.01). Moderator and dosage analyses of the dataset found no significant program effects. Analyses of the nonimputed dataset comparing program users with controls found additional significant program effects on eating practices (Δ=0.09, P=.03), exercise self-efficacy (Δ=0.12, P=.03), exercise planning (Δ=0.18, P=.03), and aging beliefs (Δ=0.17, P=.01). Moderator analysis of this dataset also found significant moderator effects of gender on multiple measures of exercise. CONCLUSIONS: A Web-based health promotion program showed promise for making a significant contribution to the short-term dietary and exercise practices of older working adults. Gender effects suggest that the program effects on exercise are due mainly to improvements among women.

Unaffected family members report improvements in daily routine sun protection 2 years following melanoma genetic testing.

PURPOSE: Reducing ultraviolet radiation exposure may decrease melanoma risk in the hereditary melanoma setting. It is unknown whether genetic counseling and test reporting of CDKN2A/p16 mutation status promote long-term compliance with photoprotection recommendations, especially in unaffected mutation carriers. METHODS: This study evaluated changes 2 years following melanoma genetic testing in self-reported practice of sun protection (sunscreen, photoprotective clothing, and ultraviolet radiation avoidance) among 37 members of two CDKN2A/p16 kindreds (10 unaffected carriers, 11 affected carriers, and 16 unaffected noncarriers; response rate = 64.9% of eligible participants). RESULTS: Multivariate profile analysis indicated that all three participant groups reported increased daily routine practice of sun protection 2 years following melanoma genetic testing (P < 0.02), with 96.9% reporting that at least one sun protection behavior was part of their daily routine, up from 78.1% at baseline (P < 0.015). Unaffected carriers (P < 0.024) and unaffected noncarriers (P < 0.027) reported significantly more frequent use of photoprotective clothing. Affected carriers maintained adherence to all sun protection behaviors. Reported sunburns in the past 6 months decreased significantly (P < 0.018). CONCLUSION: Members of high-risk families reported increased daily routine sun protection and decreased sunburns 2 years following melanoma genetic testing, with no net decline in sun protection following negative test results. Thus, genetic testing and counseling may motivate sustained improvements in prevention behaviors.

Perceived risk following melanoma genetic testing: a 2-year prospective study distinguishing subjective estimates from recall.

A major goal of predictive genetic testing is to alert people to their risk before illness onset; however, little is known about how risk perceptions change following genetic testing and whether information is recalled accurately over time. In the United States, a CDKN2A/p16 mutation confers 76 % lifetime risk of melanoma. Following genetic counseling and test reporting, subjective risk estimates and recall of counselor-provided risk estimates were assessed 5 times over the next 2 years among 60 adult members of 2 extended CDKN2A/p16 kindreds. No sustained changes from baseline in risk perceptions were reported. Unaffected carriers (n = 15) consistently reported significantly lower subjective risk estimates (46 %) than they were actually given (76 %, p < 0.001) or recalled having been given (60 %, p < 0.001). Noncarriers' (n = 27) risk estimates decreased following results disclosure, but rebounded, with both subjective and recalled estimates subsequently exceeding what they were told by the counselor (both ps < 0.001). Affected carriers' (n = 18) risk estimates for developing a new melanoma corresponded well to counselor-provided information (p = 0.362). For all 3 patient groups, results were consistent across multiple risk measures and remained similar when demographic, phenotypic, and baseline behavioral contributors to melanoma risk were statistically controlled. These findings are consistent with other studies of risk perception, but additional studies of more diverse populations are needed to understand the reasons behind both the persistence of initial risk estimates and their divergence from information provided by the counselor during genetic counseling. Additionally, determining whether holding subjective risk perceptions that differ from counselor-provided information ultimately affects adherence to management recommendations will help guide the presentation of risk information in genetic counseling practice.

Genetic testing for hereditary melanoma and pancreatic cancer: a longitudinal study of psychological outcome.

OBJECTIVE: CDKN2A/p16 mutations confer 76% lifetime risk of melanoma and up to 17% lifetime risk of pancreatic cancer. Our objective was to determine the short- and long-term impact of CDKN2A/p16 genetic counseling and test reporting on psychological distress, cancer worry, and perceived costs and benefits of testing. METHODS: Prospective changes in anxiety, depression, and cancer worry following CDKN2A/p16 counseling and test reporting were evaluated at multiple assessments over 2 years among 60 adult members of melanoma-prone families; 37 participants completed the 2-year follow-up. Quantitative and qualitative assessments of the costs and benefits of testing were carried out. Outcomes were evaluated among unaffected noncarriers (n = 27), unaffected carriers (n = 15), and affected carriers (n = 18). RESULTS: Reported anxiety and depression were low. For carriers and noncarriers, anxiety decreased significantly throughout the 2-year period, whereas depression and melanoma worry showed short-term decreases. Worry about pancreatic cancer was low and decreased significantly. In all groups, test-related distress and uncertainty were low, regret was absent, and positive experiences were high. All participants (>93% at each assessment) reported at least one perceived benefit of genetic testing; only 15.9% listed any negative aspect. Carriers reported increased knowledge about melanoma risk and prevention (78.3%) and increased prevention and screening behaviors for self and family (65.2%). Noncarriers reported increased knowledge (95.2%) and emotional benefits (71.4%). CONCLUSION: Among US participants familiar with their hereditary melanoma risk through prior epidemiological research participation, CDKN2A/p16 genetic testing provides multiple perceived benefits to both carriers and noncarriers without inducing distress in general or worry about melanoma or pancreatic cancer.

Patterns of photoprotection following CDKN2A/p16 genetic test reporting and counseling.

BACKGROUND: The impact of melanoma genetic testing and counseling on photoprotective behaviors is unknown. OBJECTIVE: To determine if genetic testing and counseling alter compliance with photoprotection recommendations. METHODS: Reported use of sunscreen, protective clothing, and sun avoidance by 59 members of CDKN2A/p16-mutation positive pedigrees was assessed as a function of mutation status and melanoma history, before, immediately after, and 1 month following test reporting. RESULTS: Intentions to practice all photoprotective behaviors increased in all participant groups (P < .0001). At 1 month, 33% of participants reported the adoption of a new photoprotective behavior. Subpopulation analyses identified different patterns of change in photoprotection relative to baseline (P < .005), with no net decline in any group. LIMITATIONS: This initial study of CDKN2A/p16 families is small and awaits replication in a larger sample. CONCLUSION: Melanoma genetic testing and counseling enhanced intentions to implement photoprotective strategies and did not result in reduced compliance in the CDKN2A/p16-subpopulation.

CDKN2A/p16 genetic test reporting improves early detection intentions and practices in high-risk melanoma families.

Genetic testing for melanoma has yet to enter routine clinical use because of the scarcity of available data on the effect of test reporting. A prospective study of 59 members of Utah CDKN2A/p16 mutation-positive pedigrees was conducted to establish the effect of CDKN2A/p16 genetic test reporting on melanoma early detection intentions and behaviors (total body skin examination and skin self-examination) in a high-risk population. Behavioral assessments were made at baseline, immediately after CDKN2A/p16 test reporting and counseling, and at 1-month follow-up (42 participants). Baseline screening practices were poor relative to current recommendations, especially among participants without a personal history of melanoma. Changes from baseline practice were evaluated in three groups of participants (CDKN2A/p16+ with history of melanoma, CDKN2A/p16+ without melanoma history, and CDKN2A/p16-). Across multiple measures, test reporting caused CDKN2A/p16 mutation carriers without a melanoma history to improve to the level of adherence reported by participants with a melanoma history, without decreasing compliance of the CDKN2A/p16- group. Compared with baseline, CDKN2A/p16+ participants without a melanoma history reported greater intention to obtain total body skin examinations (P < 0.0001), increased intentions and adherence to skin self-examination recommendations (P < 0.01 and P < 0.001, respectively), and increased number of body sites examined at 1 month (P < 0.002); further, 55% reported adopting a new screening behavior at follow-up. Test reporting also improved skin self-examination adherence among CDKN2A/p16- participants (P < 0.03). The finding that CDKN2A/p16 test reporting enhances compliance with early detection measures among CDKN2A/p16+ participants without diminishing the compliance of CDKN2A/p16- participants suggests a favorable risk-benefit ratio for melanoma genetic testing in high-risk patients.

Melanoma genetic counseling and test reporting improve screening adherence among unaffected carriers 2 years later.

BACKGROUND: A major goal of predictive genetic testing for melanoma is to promote early detection to reduce mortality. This study evaluated the long-term impact of melanoma genetic test reporting and counseling on screening adherence. METHODS: This study assessed adherence to recommendations for annual total body skin examinations (TBSE) and monthly skin self-examinations (SSE) among 37 members of Utah CDKN2A/p16 kindreds (10 unaffected carriers, 11 affected carriers, and 16 unaffected noncarriers; response rate = 64.9% of eligible participants). RESULTS: Two years following test reporting, adherence to annual TBSE among unaffected carriers increased from 40% to 70%. However, unaffected noncarriers' adherence decreased from 56% to 13%. Affected carriers reported TBSEs at both assessments (91% and 82%, respectively). Monthly SSE frequency remained highly variable in all patient groups: at 2 years, 29.7% reported monthly SSEs, 27.0% reported more frequent self-examinations, and 43.2% reported underscreening. However, SSE quality improved significantly: participants checked more body sites at 2 years than at baseline, especially feet, shoulders, legs, and genitals. Perceived logistic barriers to TBSEs (e.g., expensive, inconvenient) and SSEs (hard to remember, time-consuming) predicted lower adherence. CONCLUSIONS: Unaffected carriers reported increased TBSE adherence and thoroughness of SSEs 2 years following melanoma genetic test reporting, suggesting clinical benefit in this modest sample. Unaffected noncarriers reported comparable gains in SSE thoroughness, but decreased TBSEs. IMPACT: Melanoma genetic counseling and test reporting may improve adherence among unaffected carrier members of p16 families. Further interventions to reduce logistic barriers and to promote continued screening adherence among unaffected noncarrier family members may be needed.

Melanoma risk factors, perceived threat and intentional tanning: an international online survey.

Cutaneous melanoma continues to increase in incidence in many countries, and intentional tanning is a risk factor for melanoma. The aim of this study was to understand how melanoma risk factors, perceived threat and preferences for a suntan relate to intentional tanning. Self-report data were collected on behalf of GenoMEL (www.genomel.org) from the general population using an online survey. A total of 8178 individuals completed the survey, with 72.8% of respondents being from Europe, 12.1% from Australia, 7.1% from the US, 2.5% from Israel and 5.5% from other countries. Seven percent of respondents had previously been diagnosed with melanoma and 8% had at least one first-degree relative with a previous melanoma. Overall, 70% reported some degree of intentional tanning during the past year, and 38% of respondents previously diagnosed with melanoma had intentionally tanned. The total number of risk factors was positively correlated with perceived risk of melanoma [correlation coefficient (rho) = 0.27], and negatively correlated with intentional tanning (rho = -0.16). Preference for a dark suntan was the strongest predictor of intentional tanning [regression coefficient (beta) = 0.35, P<0.001], even in those with a previous melanoma (beta = 0.33, P<0.01). A substantial proportion of participants reported having phenotypic and behavioural risk factors for melanoma. The preference regarding suntans seemed more important in the participants' decision to intentionally tan than their perceived risk of developing melanoma, and this finding was consistent among respondents from different countries. The drive to sunbathe to tan is a key factor to be moderated if melanoma incidence is to be reduced.
