RESUMO
The objectives of this study were to assess breast density knowledge and breast density awareness, and to identify information associated with intention to complete routine and supplemental screening for breast cancer in a diverse sample of women age eligible for mammography. We quantitatively (self-report) assessed breast density awareness and knowledge (N = 264) in black (47.7%), Latina (35.2%), and white (17%) women recruited online and in the community. Most participants reported having heard about breast density (69.2%); less than one third knew their own breast density status (30.4%). Knowing their own breast density, believing that women should be notified of their breast density in their mammogram report, and feeling informed if being provided this information are associated with likelihood of completing mammogram. Intending mammogram completion and knowledge regarding the impact of breast density on mammogram accuracy are associated with likelihood of completing supplemental ultrasound tests of the breast. These findings help inform practitioners and policy makers about information and communication factors that influence breast cancer screening concerns and decisions. Knowing this information should prepare practitioners to better identify women who may have not been exposed to breast density messages.

This study aimed (i) to determine whether people could be differentiated on the basis of their sun protection belief profiles and individual characteristics and (ii) explore the use of a crowdsourcing web service for the assessment of sun protection beliefs. A sample of 500 adults completed an online survey of sun protection belief items using Amazon Mechanical Turk. A two-phased cluster analysis (i.e., hierarchical and non-hierarchical K-means) was utilized to determine clusters of sun protection barriers and facilitators. Results yielded three distinct clusters of sun protection barriers and three distinct clusters of sun protection facilitators. Significant associations between gender, age, sun sensitivity, and cluster membership were identified. Results also showed an association between barrier and facilitator cluster membership. The results of this study provided a potential alternative approach to developing future sun protection promotion initiatives in the population. Findings add to our knowledge regarding individuals who support, oppose, or are ambivalent toward sun protection and inform intervention research by identifying distinct subtypes that may best benefit from (or have a higher need for) skin cancer prevention efforts.

OBJECTIVE: Predictive and external validity was studied among cluster profiles for sun protection behavior within stages from Transtheoretical Model of behavior change using follow-up data. METHODS: Data from participants in a home-based expert system were analyzed. Longitudinal patterns of clusters on the precontemplation, contemplation, and preparation stages of change were assessed. Differences between clusters on membership in action/maintenance stages and scores on the Sun Protection Behavior Scale (SPBS) were measured at 12 and 24 months after intervention. RESULTS: Differences between clusters on stage progression and on scores from the SPBS were found at 12 and 24 months after intervention at all stages. DISCUSSION: Predictive and external validity of sun protection subtypes was established using sun protection variables after a stage-matched intervention. Results provide information to improve interventions for sun protection.

The aim of this study is to identify replicable cluster subtypes within the precontemplation stage of change for sun protection. Secondary data analysis of baseline data from a sample of participants in a home-based expert system intervention was performed. Three random samples were selected from participants in the precontemplation stage (N = 570). Cluster analyses were performed using the scales of pros, cons, and self-efficacy. Interpretability of pattern, pseudo F-test, and dendograms were used to determine the number of clusters. A four-cluster solution replicated across subsamples. Significant differences between clusters on the nine processes of change and on behavioral measures were found. Cluster solutions were robust, interpretable and with good initial external validity. They replicated patterns found for other behaviors, demonstrating long-term predictability and providing basis for tailored interventions.

Background: Many states have enacted breast density laws, requiring that women be informed of their breast density status; however there is currently no consensus for screening guidelines or recommendations for women with dense breasts. The objective of this study is to access physician views about breast density and their practices for breast cancer screening of women with dense breasts in light of breast density laws. Materials and Methods: Setting: Academic medical centers, community and private practices mostly in New York City. Participants: Primary care providers (PCPs), radiologists and gynecologists. Procedure: We conducted the study through anonymous, self-administered surveys about physician knowledge, attitudes, and practices regarding screening of women with dense breasts. Bivariate and multivariate analyses were performed to assess differences between PCPs and specialists. Results: We received 155 responses of which 75% were female, 77% were attending-level physicians, 42% were PCPs, 28% were radiologists, 17% were gynecologists, and 9% other. Almost half of the respondents (48%) were unaware of breast density laws, and two-thirds (67%) felt they needed more education about breast density and supplemental screening. More than half of the respondents (62%) were unaware of the increased risk of breast cancer related to dense breasts. Compared to specialists, PCPs were less aware of their state's breast density laws (odds ratio [OR] 0.21; 95% confidence interval [CI] 0.09-0.50) and of the increased breast cancer risk for women with dense breasts (OR 0.23; 95% CI 0.09-0.60). Conclusion: Breast density laws have not translated into greater knowledge of breast density and recommendations for supplemental screening among PCPs.

OBJECTIVES: We reviewed the literature on breast density knowledge and breast density awareness to explore what challenges are faced by this area of research. METHOD: A review of PubMED, PsycINFO, and CINAHL databases was performed. Studies were published in peer-reviewed journals (in all years available) and written in English. The broad search terms used were ["breast density"] AND ["knowledge" OR "awareness"]. Eligible articles were included in the final analysis after meeting the following inclusion criteria: (1) the records had to quantitatively examine and report breast density knowledge and awareness, (2) the number of participants in the sample had to be clearly specified, and (3) studies reporting differences in breast density knowledge and awareness between racial and ethnic groups were included in the review. RESULTS: Of the 277 articles identified, only 5 met inclusion criteria and addressed breast density knowledge and awareness. Characteristics of studies and results were examined. CONCLUSIONS: There is insufficient evidence to determine a pattern of breast density knowledge and awareness in women. More quality studies are needed that focus on how well women understand the relationship between breast density, breast cancer risk, and breast cancer screening, especially in diverse populations.

OBJECTIVE: Mediation analyses of sun protection were conducted testing structural equation models using longitudinal data with three waves. An effect was said to be mediated if the standardised path between processes of change, decisional balance and sun protection outcomes was significant. DESIGN: Longitudinal models of sun protection using data from individuals in the precontemplation (N = 964) and preparation (N = 463) stages who participated of an expert system intervention. MAIN OUTCOME MEASURES: Nine processes of change for sun protection, decisional balance constructs of sun protection (pros and cons), sun avoidance behaviour and sunscreen use. RESULTS: With the exception of two processes in the preparation stage, processes of change predicted the pros (r = .126-.614), and the pros predicted the outcomes (r = .181-.272). Three models with the cons as mediator in the preparation stage, and none in the precontemplation stage, showed a mediated relationship between processes and outcomes. CONCLUSION: In general, mediation analyses found both the process of change-to-pros and pros-to-behaviour paths significant for both precontemplation and preparation stages, and for both sun avoidance and sunscreen use outcomes. Findings provide support for the importance of assessing the role of underlying risk cognitions in improving sun protection adherence.

Purpose. We reviewed the literature on sun protection beliefs in Hispanics living in the United States to explore what challenges are faced by area of research. Method. A review of PubMED, PsycINFO, and CINAHL databases was performed. Studies were published in peer-reviewed journals (in all years available) and written in English. The search terms used were ["skin cancer" OR "sun protection"] AND ["Latino" OR "Hispanic"] AND "beliefs." Eligible papers were included in the final analysis after meeting the following inclusion criteria: (1) the records had to quantitatively examine and report sun protection beliefs in Hispanics, (2) the number of Hispanic participants in the sample had to be clearly specified, and (3) studies reporting differences in sun protection beliefs between Hispanics and other racial and ethnic groups were included in the review. Results. Of the 92 articles identified, 11 met inclusion criteria and addressed sun protection beliefs regarding skin cancer seriousness and susceptibility, and benefits and barriers of sun protection and skin cancer risk behaviors. Characteristics of studies and results were examined. Conclusion. There is insufficient evidence to determine a pattern of sun protection beliefs among Hispanics in the United States. More quality studies are needed which focus on sun protection beliefs in Hispanics.
RESUMO
The Information-Motivation-Behavioral Skills model examines factors that are used to initiate and maintain sexual and reproductive health promotion behaviors. The present study evaluated the association among these constructs as it is applied to sexually active heterosexual adults with steady partners, using a Structural Equation Modeling approach. At the same time, it was analyzed if the same model structure could be generalized to two samples of participants that produced the results following two different formats for data collection. Two-hundred ninety one participants completed the Information-Motivation-Behavioral Skills Questionnaire (Spanish version), and 756 participants completed an Internet version on the instrument. The proposed model fits the data for both groups, supporting a predictive and positive relationship among all of the latent variables, with Information predicting Motivation, and Motivation therefore predicting Behavioral Skills. The findings support the notion that there are important issues that need to be addressed when promoting HIV prevention.
RESUMO
Self-efficacy has been defined as one of the factors that may facilitate or impede safer sex. Studies reveal that peoples in steady relationships practice safer sex less often that those in casual relationships. We conducted a study with 447 sexually active heterosexual adults. A self-administered questionnaire was designed to study the sexual behavior, the male condom use and the practice of mutual masturbation, and the self-efficacy toward these practices. Results show that most men are sexually active and that there is a low frequency of male condom use and the practice of mutual masturbation as safer sex. The majority of those who use the male condom are engage in casual relationships. However, participants have high levels of self-efficacy toward these practices. Although self-efficacy is one of the factors that influence in deciding to practice safer sex, it is not sufficient to reach this goal.
