    ABSTRACT: Background Breast cancer patients face several preference-sensitive treatment decisions. Feelings such as regret or having had inadequate information about these decisions can significantly alter patient perceptions of recovery and recurrence. Numerous objective measures of decision quality (e.g., knowledge assessments, values concordance measures) have been developed; there are far fewer measures of subjective decision quality and little consensus regarding how the construct should be assessed. The current study explores the psychometric properties of a new subjective quality decision measure for breast cancer treatment that could be used for other preference sensitive decisions. Methods320 women aged 20¿79 diagnosed with AJCC stage 0 ¿ III breast cancer were surveyed at two cancer specialty centers. Decision quality was assessed with single items representing six dimensions: regret, satisfaction, and fit as well as perceived adequacy of information, time, and involvement. Women rated decision quality for their overall treatment experience and surgery, chemotherapy, and radiation decisions separately. Principle components was used to explore factor structure. After scales were formed, internal consistency was computed using Cronbach¿s alpha. The association of each of the four final scale scores was examined by Pearson correlation.ResultsFor overall breast cancer treatment as well as surgery, chemotherapy, and radiation decisions, the six items yielded a single factor solution. Factor loadings of the six decision items were all above .45 across the overall and treatment-specific scales, with the exception of ¿Right for You¿ for chemotherapy and radiation. Internal consistency was 0.77, 0.85, 0.82, and 0.78 for the overall, surgery, chemotherapy, and radiation decision quality scales, respectively.Conclusions Our measure of subjective appraisal of breast cancer treatment decisions includes 5 related elements; regret and satisfaction as well as perceived adequacy of information, time, and involvement. Future research is needed to establish norms for the measure as is further psychometric testing, particularly to examine how it is associated with outcomes such as quality of life, psychological coping and objective decision quality.

    ABSTRACT: Background: Hispanics have a higher incidence of cardiovascular disease (CVD) than non-Hispanic whites (NHWs) but are underrepresented in clinical trials. We describe baseline demographics and CVD behavioral risk factors among participants of a bi-ethnic, church-based, primary prevention trial. Methods: The Stroke Health and Risk Education (SHARE) project is a cluster-randomized, multi-component, faith-based, behavioral intervention that enrolled Mexican Americans (MAs) and NHWs from Catholic churches in Corpus Christi, Texas. Recruitment strategies included church announcements, parish liaisons and recruitment in pairs. The proportion of participants whose sodium intake, fruit intake, vegetable intake, and physical activity all met guideline recommendations was calculated. Ethnic comparisons of behavioral CVD risk factors were performed using descriptive statistics and regression models. Results: A total of 760 baseline interviews were conducted; 84% of subjects were MAs. MAs were younger (51 vs. 59, p<0.01) and more likely to be women (66% vs. 52% p<0.01) than NHWs. Only 0.4% of participants met all recommendations for diet and physical activity. There were no ethnic differences in sodium (p=0.64), fruit intake (p=0.17) or physical activity (p=0.59). MAs ate fewer cups of vegetables per week than NHWs (1.36 vs. 1.75, p<0.01). Conclusion: Church-based recruitment of MAs was effective in this bi-ethnic community. Less than 1% of the participants met all guideline lifestyle recommendations for CVD prevention and there were few ethnic differences in CVD risk factors suggesting a need for the intervention in both MAs and NHWs.

    ABSTRACT: Historically, African Americans have been underrepresented in clinical trials (CTs) compared to whites. A growing number of research institutions have created CT registries to match volunteers with appropriate studies. In a sample of 745 African Americans from 16 churches, we tested the impact of a culturally tailored intervention aimed at increasing enrollment in a university-based CT registry. Half of the churches received a culturally tailored CT education program (intervention) and half of the churches received a program about healthy eating (comparison). The main outcomes were the odds of post-test self-reported enrollment and verified enrollment. Using linear regression, post-test willingness to participate in a CT was also assessed. Odds of verified enrollment were higher in the intervention than comparison group (OR=2.95, 95% CI: 1.33-6.5, p=0.01). Post-test self-reported enrollment in the registry was also higher among the intervention group than comparison group members (OR=1.94, 95% CI: 1.08-3.47, p=0.03). Willingness to participate in a future CT was higher in the intervention group (β=0.74, p=0.02). A culturally tailored education program about CTs can increase enrollment of African Americans in a university-based clinical trials registry. Community engagement and health education workshops may improve minority CT enrollment over time. Copyright © 2014. Published by Elsevier Ireland Ltd.

    ABSTRACT: This article reports on the association between ethnic identity and condom use among Black African men in the rural areas of the Eastern Cape Province, South Africa. Individual face-to-face structured interviews were conducted by trained community research assistants among 1,656 men who had undergone traditional initiation and male circumcision. Logistic regression analyses were used to explore the association between two components of ethnic identity (cultural affiliation and cultural alienation) and condom use. Overall, 49.2 % of the participants reported using condoms consistently and, of these users, 66.4 % used them correctly. Logistic regression adjusting for age, employment status, education level, and nation of origin showed that participants who expressed high as opposed to low cultural affiliation were significantly more likely to use condoms consistently and correctly when having sex, especially if they reported to have more than one sexual partner. Cultural alienation was negatively related with consistent condom use, whereas its association with correct use was unclear. The findings of this study suggest that positively emphasizing the ethnic identity of African black men may promote condom use.

    ABSTRACT: Smokeless tobacco in South Africa is commonly used in the form of "snuff" or chewing tobacco. This paper reports its use among secondary school learners and provides evidence of its association with demographic characteristics, tobacco smoking, and socioeconomic status. Data were derived from a nationally representative study conducted in 2008 among 10,270 grade 8-11 learners from 192 schools in South Africa. Data were collected in class using self-administered questionnaires. Multiple logistic regression analyses were used to examine correlates of past month smokeless tobacco use. Nationally, 12.4% of learners used smokeless tobacco such as chewing tobacco or snuff in the month preceding the survey, with significantly higher rates among males (13.6%) than females (10.6%). Smokeless tobacco use differed between "race" groups, with African (12.8%) and Colored (11.7%) learners having the highest rates of past month use. Grade 8 learners (15.3%) reported significantly higher rates of use than grade 11 learners (9.1%). Current cigarette smokers (21.3%) reported a higher prevalence of smokeless tobacco use than noncurrent smokers (10.1%). Logistic regression of past month smokeless tobacco use showed significant associations with race, grade, school socioeconomic level, urbanicity, current cigarette smoking, and having first smoked a cigarette before the age of 10 years. These findings provide evidence for policy makers and program developers to develop targeted and tailored interventions for young people regarding smokeless tobacco use.

    ABSTRACT: Over 45% of American women 20-39 years old are at risk for type 2 diabetes, cardiovascular disease, and other health conditions because they are overweight or obese. The prevalence of overweight and obesity is disproportionately high among low-income women. This paper describes the study design and rationale of a community based intervention (Mothers In Motion, MIM) aimed to prevent weight gain among low-income overweight and obese mothers18-39 years old by promoting stress management, healthy eating, and physical activity.Methods/design: Peer recruiters approached participants from 5 Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Michigan. The MIM delivers theory-based, culturally-sensitive intervention messages via a combination of DVDs and peer support group teleconferences (PSGTs). The DVD features African American and white overweight and obese WIC mothers who participated in a healthy lifestyle intervention patterned after MIM. The PSGTs are led by paraprofessionals from Michigan State University Extension and WIC providers in Michigan who are trained in motivational interviewing and group facilitation skills. Participants are randomly assigned to an intervention (n = 350) or comparison group (n = 175). The intervention group receives a 16-week intervention on a weekly or bi-weekly basis. Participants are asked to watch 10 MIM DVD chapters at home and join 10 PSGT sessions by phone. The comparison group receives printed educational materials. The primary outcome is body weight. Secondary outcomes include dietary fat, fruit, and vegetable intake; physical activity; stress, and affect. Mediators are self-efficacy, emotional coping response, social support, and autonomous motivation. Telephone interviews and in-person data collection at WIC offices occur at 3 time points: baseline, immediately, and 3 months after the 16-week intervention. If MIM shows effectiveness, it could have a favorable impact on public health and community programs. The DVDs and PSGTs will be disseminated in WIC, Extension, clinical practice that promote healthy lifestyles for similar target audiences to make a broad contribution to the prevention of weight gain in low-income mothers. Also, our methodology can be adapted by researchers and community stakeholders to help other low-income populations prevent weight gain.Trial regestration: Clinical Trials Number: NCT01839708.

    ABSTRACT: Smokers who report quitting without prior planning have been shown to report longer abstinence compared with those who planned. Little is known about unplanned quitting (UQ) among U.S. smokers, minorities, or nondaily and light smokers. Using an online panel, we recruited equal numbers of Black, White, and Latino nondaily, light daily, and moderate/heavy daily smokers. Of the 1,127 who reported a past year quit attempt, we queried whether it was planned and the maximum number of days abstinent. Overall, 38% reported that their last quit attempt was unplanned. The impact of planned versus unplanned quitting interacted with smoking level and race. Among White moderate/heavy smokers, mean days abstinent was 99 for those who reported an unplanned quit attempt compared with 60 days for those who reported having planned, p = .02. Among Black moderate/heavy smokers, the mean days abstinent was higher among those whose last attempt was planned, 92 days, compared with 56 days among those whose last attempt was unplanned, p = .09. The pattern among Latinos resembled Whites but was not significant. Results remained after adjusting for confounds such as age, gender, education, income, time to first cigarette, and menthol use. There were no significant differences in abstinence by quit type for light or nondaily smokers. Future studies are needed to elucidate why UQ appears to have differential effectiveness across racial/ethnic groups and different levels of cigarette use. Research examining the impact of UQ on long-term quitting, something not addressed here, is needed.

    ABSTRACT: Objective Test the impact of tailoring CRC screening messages for African Americans (AAs) using novel theoretical variables and to examine moderating effect of communication preferences. Methods Participants were randomized to receive two minimally tailored or two enhanced tailored print newsletters addressing CRC. The enhanced intervention was tailored on self-determination theory and other novel psychological constructs. Minimal tailoring only used information available in the patient's EHR. The primary outcome was CRC screening based on EHR. Participants were AA members aged 50-74 of an integrated health care delivery system not up to date on CRC screening. Results We enrolled 881 participants. CRC screening participation rates at 1-year follow up were 20.5% and 21.5% in the minimally and enhanced tailored groups, respectively. Communication preferences moderated the impact of the intervention. Specifically, among those with an autonomous communication preference, screening rates in the minimally and enhanced tailored groups were 17.1% and 25.9%, respectively, while no intervention effect was evident among those with a directive preference. Conclusion Future research is needed to explore the impact of communication preference tailoring for other health behaviors and among other populations.

    ABSTRACT: This study examined racial/ethnic differences among patients in clinical trial (CT) enrollment, refusal rates, ineligibility, and desire to participate in research within the National Cancer Institute's Community Cancer Centers Program (NCCCP) Clinical Trial Screening and Accrual Log. Data from 4509 log entries were evaluated in this study. Four logistic regression models were run using physical/medical conditions, enrollment into a CT, patient eligible but declined a CT, and no desire to participate in research as dependent variables. Age ≥ 65 years (OR = 1.51, 95% CI = 1.28-1.79), males (OR = 2.28, 95% CI = 1.92-2.71), and non-Hispanic black race (OR = 1.53, 95% CI = 1.2-1.96) were significantly associated with more physical/medical conditions. Age ≥ 65 years was significantly associated with lower CT enrollment (OR = 0.83, 95% CI = 0.7-0.98). Males (OR = 0.78, 95% CI = 0.65-0.94) and a higher grade level score for consent form readability (OR = 0.9, 95% CI = 0.83-0.97) were significantly associated with lower refusal rates. Consent page length ≥ 20 was significantly associated with lower odds of "no desire to participate in research" among CT decliners (OR = 0.75, 95% CI = 0.58-0.98). There were no racial/ethnic differences in CT enrollment, refusal rates, or "no desire to participate in research" as the reason given for CT refusal. Higher odds of physical/medical conditions were associated with older age, males, and non-Hispanic blacks. Better management of physical/medical conditions before and during treatment may increase the pool of eligible patients for CTs. Future work should examine the role of comorbidities, sex, age, and consent form characteristics on CT participation. Cancer 2013. © 2013 American Cancer Society.

    ABSTRACT: Abstract Background: The current study examined the effects of a Web-based tailored parenting intervention on increasing fruit and vegetable intake in African American families. Methods: Forty-seven African American parents (mean age, 41.32±7.30; 93.6% female) with an adolescent (mean age, 13.32±1.46; 59.6% female) participated in a Web-based autonomy-support parenting tailored intervention session to increase both parent and youth fruit and vegetable (F&V) intake. The session lasted 45-60 minutes and included three phases: a feedback phase; a Web-based information phase, and a goal-setting and action plan phase. Self-reported measures of parenting skills [based on autonomy (choice), support, and communication] and F&V intake (assessed as average daily intake) were assessed at baseline and at a 1-week follow-up session. Results: There was a significant increase in parents' self-reports of daily fruit intake from pretest to the 1-week follow-up. Parent and adolescent combined F&V intake also significantly increased from pretest to 1-week follow-up. Overall, parents reported that the program was easy to navigate and that they enjoyed participating in the Web-based online program. Conclusions: Current findings provide preliminary support for an autonomy-support parent tailored Web-based program for improving dietary intake in African American families.

    ABSTRACT: Although African Americans suffer disproportionately from smoking related illnesses, few studies have examined ethnic differences in processing health and smoking information. This study examines ethnic differences in unmotivated smokers' preference for receiving counseling to quit smoking in an expert oriented style, and whether ethnicity and style of counseling predicts alliance with counselor, perceived influence on smoking, and treatment satisfaction. Participants were 255 community residents (57% male; 68% African American) in a randomized controlled trial comparing expert-oriented Health Education (HE) with patient-centered Motivational Interviewing. Compared to Whites, African American participants had a significantly higher preference for being told what to do by an expert (p

    ABSTRACT: Background. The South African (SA) government has implemented comprehensive tobacco control measures in line with the requirements of the Framework Convention on Tobacco Control. The effect of these measures on smoking prevalence and smoking-related attitudes, particularly among young people, is largely unknown.Objective. To describe the impact of a comprehensive health promotion approach to tobacco control amongst SA school learners. Methods. Four successive cross-sectional Global Youth Tobacco Surveys (GYTSs) were conducted in 1999, 2002, 2008 and 2011 among nationally representative samples of SA grades 8 - 10 school learners. We assessed the prevalence of current smoking (having smoked a cigarette on ≥1 day in the 30 days preceding the survey) and smoking-related attitudes and behaviours. Results. Over the 12-year survey period current smoking among learners declined from 23.0% (1999) to 16.9% (2011) - a 26.5% reduction. Reductions in smoking prevalence were less pronounced amongst girls and amongst black learners. We observed an increase in smoking prevalence amongst learners between 2008 and 2011. Smoking-related attitudes and behaviours showed favourable changes over the survey period. Conclusion. These surveys demonstrate that the comprehensive and inter-sectorial tobacco control health promotion strategies implemented in SA have led to a gradual reduction in cigarette use amongst school learners. Of concern, however, are the smaller reductions in smoking prevalence amongst girls and black learners and an increase in smoking prevalence from 2008 to 2011. Additional efforts, especially for girls, are needed to ensure continued reduction in smoking prevalence amongst SA youth.

    ABSTRACT: According to the World Health Organization's 2008 GLOBOCAN report, 64% of global cancer deaths -- and 56% of cancer cases -- were registered in countries in Africa, Asia, or Latin America. So while cancer is unquestionably a global burden, its reach in the developing world points to the need for specialized study on cancer in these countries. Cancer Epidemiology: Low- and Middle-Income Countries and Special Populations reviews the current status of cancer epidemiologic research and training -- rationale, requisite infrastructure, methodologic principles, and illustrative examples in low- and middle-income countries -- in order to facilitate future advances by trained health professionals. The result is a valuable resource for both program leaders and graduate and post-graduate students pursuing careers in international cancer epidemiologic research. Features: In addition to LMICs, addresses reports on specific studies conducted in Africa, Asia, Central and South America, and the Middle East, as well as studies in Australia, Europe, North America and in populations that migrate from LMICs to developed countries Includes detailed training requirements and examples of curricula that will enable graduate and post-graduate students to pursue careers in international cancer epidemiologic research Summarizes and reviews research studies that are in progress concerning major prevalent cancers of the breast, uterine cervix, lung and bronchus, upper aerodigestive tract, stomach, liver, colon, and HIV-associated cancers For program leaders and graduate and post-graduate students pursuing careers in international cancer epidemiologic research

    ABSTRACT: AIMS: To assess the effects of adding motivational interviewing (MI) counseling to nicotine patch for smoking cessation among homeless smokers. DESIGN: Two-group randomized controlled trial with 26-week follow-up. PARTICIPANTS AND SETTING: A total of 430 homeless smokers from emergency shelters and transitional housing units in Minneapolis/St Paul, Minnesota, USA. INTERVENTION AND MEASUREMENTS: All participants received 8-week treatment of 21-mg nicotine patch. In addition, participants in the intervention group received six individual sessions of MI counseling which aimed to increase adherence to nicotine patches and to motivate cessation. Participants in the standard care control group received one session of brief advice to quit smoking. Primary outcome was 7-day abstinence from cigarette smoking at 26 weeks, as validated by exhaled carbon monoxide and salivary cotinine. FINDINGS: Using intention-to-treat analysis, verified 7-day abstinence rate at week 26 for the intervention group was non-significantly higher than for the control group (9.3% versus 5.6%, P = 0.15). Among participants who did not quit smoking, reduction in number of cigarettes from baseline to week 26 was equally high in both study groups (-13.7 ± 11.9 for MI versus -13.5 ± 16.2 for standard care). CONCLUSIONS: Adding motivational interviewing counseling to nicotine patch did not increase smoking rate significantly at 26-week follow-up for homeless smokers.

    ABSTRACT: BACKGROUND: Smoking, poor diet, and physical inactivity account for as much as 60% of cancer risk. Latinos experience profound disparities in health behaviors, as well as the cancers associated with them. Currently, there is a dearth of controlled trials addressing these health behaviors among Latinos. Further, to the best of our knowledge, no studies address all three behaviors simultaneously, are culturally sensitive, and are guided by formative work with the target population. Latinos represent 14% of the U.S. population and are the fastest growing minority group in the country. Efforts to intervene on these important lifestyle factors among Latinos may accelerate the elimination of cancer-related health disparities.Methods/design: The proposed study will evaluate the efficacy of an evidence-based and theoretically-driven Motivation And Problem Solving (MAPS) intervention, adapted and culturally-tailored for reducing cancer risk related to smoking, poor diet, and physical inactivity among high-risk Mexican-origin smokers who are overweight/obese (n = 400). Participants will be randomly assigned to one of two groups: Health Education (HE) or MAPS (HE + up to 18 MAPS counseling calls over 18 months). Primary outcomes are smoking status, servings of fruits and vegetables, and both self-reported and objectively measured physical activity. Outcome assessments will occur at baseline, 6 months, 12 months, and 18 months. DISCUSSION: The current study will contribute to a very limited evidence base on multiple risk factor intervention studies on Mexican-origin individuals and has the potential to inform both future research and practice related to reducing cancer risk disparities. An effective program targeting multiple cancer risk behaviors modeled after chronic care programs has the potential to make a large public health impact because of the dearth of evidence-based interventions for Latinos and the extended period of support that is provided in such a program.Trial registration: National Institutes of Health Clinical Trials Registry # http://www.clinicaltrials.gov/ct2/show/NCT01504919.

    ABSTRACT: INTRODUCTION: Evidence-based health promotion programs that are disseminated in community settings can improve population health. However, little is known about how effective such programs are when they are implemented in communities. We examined community implementation of an evidence-based program, Body and Soul, to promote consumption of fruits and vegetables. METHODS: We randomly assigned 19 churches to 1 of 2 arms, a colon cancer screening intervention or Body and Soul. We conducted our study from 2008 through 2010. We used the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework to evaluate the program and collected data via participant surveys, on-site observations, and interviews with church coordinators and pastors. RESULTS: Members of 8 churches in Michigan and North Carolina participated in the Body and Soul program. Mean fruit and vegetable consumption increased from baseline (3.9 servings/d) to follow-up (+0.35, P = .04). The program reached 41.4% of the eligible congregation. Six of the 8 churches partially or fully completed at least 3 of the 4 program components. Six churches expressed intention to maintain the program. Church coordinators reported limited time and help to plan and implement activities, competing church events, and lack of motivation among congregation members as barriers to implementation. CONCLUSIONS: The RE-AIM framework provided an effective approach to evaluating the dissemination of an evidence-based program to promote health. Stronger emphasis should be placed on providing technical assistance as a way to improve other community-based translational efforts.

    ABSTRACT: We used data from two telephone-administered health surveys to explore African Americans’ preferences for interviewer race. The first survey utilized African American interviewers to assess ethnic identity and aspects of healthy eating among 617 African American adults. In the second survey, interviewers of varying races queried 534 African American adults about their motivations to eat healthier. The motivation survey contained almost no racial content, whereas 40% of the ethnic identity survey assessed racial content. Using only ethnic identity survey data, we found that respondents with Afrocentric or Black American identity components were more likely to prefer African American interviewers than respondents with solely assimilated, bicultural, or multicultural identity components. Ethnic identity survey respondents were also more likely to prefer racially/ethnically matched interviewers than motivation survey respondents. Ethnic identity respondents with a college or graduate degree reported lower hypothetical comfort with a white interviewer than respondents with a high school education.

    ABSTRACT: BACKGROUND: Although current clinical practice guidelines recommend Motivational Interviewing for use with smokers not ready to quit, the strength of evidence for its use is rated as not optimal. The purpose of the present study is to address key methodological limitations of previous studies by ensuring fidelity in the delivery of the Motivational Interviewing intervention, using an attention-matched control condition, and focusing on unmotivated smokers whom meta-analyses have indicated may benefit most from Motivational Interviewing. It is hypothesized that MI will be more effective at inducing quit attempts and smoking cessation at 6-month follow-up than brief advice to quit and an intensity-matched health education condition. METHODS: A sample of adult community resident smokers (N= 255) who report low motivation and readiness to quit are being randomized using a 2:2:1 treatment allocation to Motivational Interviewing, Health Education, or Brief Advice. Over 6 months, participants in Motivational Interviewing and Health Education receive 4 individual counseling sessions and participants in Brief Advice receive one brief in-person individual session at baseline. Rigorous monitoring and independent verification of fidelity will assure the counseling approaches are distinct and delivered as planned. Participants complete surveys at baseline, week 12 and 6-month follow-up to assess demographics, smoking characteristics, and smoking outcomes. Participants who decide to quit are provided with a self-help guide to quitting, help with a quit plan, and free pharmacotherapy. The primary outcome is self-report of one or more quit attempts lasting at least 24 hours between randomization and 6-month follow-up. The secondary outcome is biochemically confirmed 7-day point prevalence cessation at 6-month follow-up. Hypothesized mediators of the presumed treatment effect on quit attempts are greater perceived autonomy support and autonomous motivation. Use of pharmacotherapy is a hypothesized mediator of Motivational Interviewing's effect on cessation. DISCUSSION: This trial will provide the most rigorous evaluation to date of Motivational Interviewing's efficacy for encouraging unmotivated smokers to make a quit attempt. It will provide also provide effect-size estimates of MI's impact on smoking cessation to inform future clinical trials and inform the clinical practice guidelines.
