OBJECTIVES We used qualitative and quantitative data collection methods to identify the health concerns of African American residents in an urban community and analyzed the extent to which there were consistencies across methods in the concerns identified. METHODS We completed 9 focus groups with 51 residents, 27 key informant interviews, and 201 community health surveys with a random sample of community residents to identify the health issues participants considered of greatest importance. We then compared the issues identified through these methods. RESULTS Focus group participants and key informants gave priority to cancer and cardiovascular diseases, but most respondents in the community health survey indicated that sexually transmitted diseases, substance abuse, and obesity were conditions in need of intervention. How respondents ranked their concerns varied in the qualitative versus the quantitative methods. CONCLUSIONS Using qualitative and quantitative approaches simultaneously is useful in determining community health concerns. Although quantitative approaches yield concrete evidence of community needs, qualitative approaches provide a context for how these issues can be addressed. Researchers should develop creative ways to address multiple issues that arise when using a mixed-methods approach.

When using community-based participatory methods to develop health promotion programs for specific communities, it is important to determine if participation differs based on sociodemographics and the extent to which program participants are demographically representative of the target community, especially when non-random recruitment methods are used. We evaluated rates of participating in a health promotion program among African American residents in an urban community and determined if program participants were representative of community residents in terms of sociodemographic factors. While participation in the program was modest, participation did not differ based on psychological factors or body mass index. However, individuals who were unemployed were significantly more likely to participate in the program compared with those who were employed. Our sample included a greater proportion of individuals who only had a high school education compared with community residents but was similar to community residents in terms of gender, marital status and employment.

Since prostate cancer continues to disproportionately affect African American men in terms of incidence, morbidity, and mortality, prostate-specific antigen (PSA) screening plays an important role in early detection, especially when men engage in informed decision making to accept or decline this test. The authors evaluated utilization of PSA testing among African American men based on factors that are important components of making informed decisions. Utilization of PSA testing was evaluated based on whether men had ever had PSA testing and PSA testing during the past year in a community-based sample of African American men ages 50 to 75 (n = 132). Overall, 64% of men (n = 85) reported that they had ever had a PSA test; the mean (SD) age for first use of PSA testing was 47.7 (SD = 7.4). The likelihood of ever having a PSA test increased significantly with physician communication (odds ratio [OR] = 14.2; 95% confidence interval [CI] = 4.20, 48.10; p = .0001) and with having an annual household income that was greater than

20,000 (OR = 9.80; 95% CI = 3.15, 30.51; p = .0001). The odds of ever having a PSA test were also decreased with each unit increase in future temporal orientation (OR = 0.66; 95% CI = 0.47, 0.93; p = .02). Of the men who had ever had PSA testing, 57% were screened during the past year. Only health insurance status had a significant independent association with having annual PSA testing (OR = 5.10; 95% CI = 1.67, 15.60; p = .004). Different factors were associated significantly with ever having PSA testing and annual testing among African American men. African American men may not be making an informed decision about prostate cancer screening.

Background: The intervention completion rate is an important metric in behavioral and intervention research; trials with limited intervention completion rates may have reduced internal validity. We examined intervention completion rates among 530 African Americans who had been randomized to an integrated (INT) or disease-specific (DSE) risk education protocol as part of a comparative effectiveness trial from September 2009 to August 2012. Methods: The interventions were developed by an academic-community partnership using community-based participatory research. Intervention completion rates were determined based on attendance at all four intervention sessions. Intervention completers were participants who completed all four sessions and noncompleters were those who did not complete any session or only completed one to three sessions following randomization. Results: Seventy-three percent of participants were intervention completers and 27% were noncompleters. There were no differences in intervention completion based on randomization to INT (72%) or DSE (75%), sociodemographic factors, or body mass index (BMI) in the total sample. Different factors were associated significantly with intervention completion within study groups. Among participants randomized to INT, the odds of intervention completion were greater with higher levels of intrinsic motivation, less exposure to information about diet and cardiovascular disease, and greater BMI. Among participants randomized to DSE, the odds of completing the intervention were associated significantly with older age and greater dietary self-efficacy. Conclusions: Many African Americans are likely to complete risk education interventions. Impact: Psychologic characteristics should be considered when determining intervention completion rates following randomization in behavioral and intervention trials.

OBJECTIVE We evaluated a risk counseling intervention designed to enhance understanding about risk factors for cancer and cardiovascular disease, to improve self-efficacy for diet and physical activity, and to increase intentions to eat healthier and be physically active. METHODS We conducted a quasi-experimental study developed by academic investigators and community stakeholders to evaluate the effects of integrated risk counseling in a community-based sample of African American adults (n = 101). The intervention provided education about the overlap in risk factors for cancer and cardiovascular disease and included components from motivational interviewing. RESULTS Changes in behavioral intentions were not statistically significant (p > .05). Participants reported significantly greater levels of self-efficacy for diet (t = 2.25, p = .03) and physical activity (t = 2.55, p = .01), and significantly increased perceived risks of developing colon cancer (chi2 = 3.86, p = .05) and having a heart attack (chi2 = 4.50, p = .03). CONCLUSIONS Integrated risk counseling may have some benefits among African Americans.

Obesity and excess weight are significant clinical and public health issues that disproportionately affect African Americans because of physical inactivity and unhealthy eating. We compared the effects of alternate behavioral interventions on obesity-related health behaviors. We conducted a comparative effectiveness education trial in a community-based sample of 530 adult African Americans. Outcomes variables were physical activity (PA) and fruit and vegetable intake. Outcomes were evaluated at baseline and 1-month following interventions about shared risk factors for cancer and cardiovascular disease (CVD) (integrated, INT) or CVD only (disease-specific). Significant increases were found in the proportion of participants who met PA guidelines from baseline (47.4%) to follow-up (52.4%) (P = 0.005). In the stratified analysis that were conducted to examine interaction between education and intervention group assignment, this effect was most apparent among participants who had ≤high school education and were randomized to INT (OR = 2.28, 95% CI = 1.04, 5.00, P = 0.04). Completing the intervention was associated with a 1.78 odds of meeting PA guidelines (95% CI = 1.02, 3.10, P = 0.04). Education about risk factors for chronic disease and evidence-based strategies for health behavior change may be useful for addressing obesity-related behaviors among African Americans.

As guidelines for prostate cancer screening have changed from an annual screening recommendation starting at age 50 to discussing the benefits and harms of screening with health care providers, it is necessary to examine other types of factors that are important to prostate cancer screening decisions among African American men. Perceived risk of developing cancer has been shown to predict cancer control behaviors and is lower among African Americans. We characterized perceived risk of developing prostate cancer among African American men from November 2009 to 2011 and evaluated the relationship between prostate cancer risk perceptions and sociodemographic characteristics, health care experiences, and knowledge and exposure to health information about cancer. Chi square tests and logistic regression were employed to determine independent associations. Overall, men did not believe they were at increased risk of developing prostate cancer; they believed their risk was equivalent to or lower than men the same age. Perceived risk of prostate cancer was associated with income (OR = 0.59, 95% CI = 0.26, 1.34, p = 0.03), hypertension (OR = 2.68, 95% CI = 1.17, 6.16, p = 0.02), and beliefs about the association between race and cancer risk (OR = 2.54, 95% CI = 1.24, 5.20, p = 0.01). Clinic and community-based approaches to improve prostate cancer risk comprehension among African American men are needed to reduce the discordance between perceived risk and epidemiological data on prostate cancer risk factors. Risk education interventions that are developed for African American men may need to integrate information about susceptibility for multiple diseases as well as address strategies for risk reduction and prevention, and chronic disease management.

Abstract B15: Motivation for cancer control changes among African Americans

Melanie Jefferson; Vanessa Briggs; Ernestine Delmoor; LaShanta J. Rice; Jerry C. Johnson; Chanita Hughes-Halbert

Patient navigation is now a standard component of cancer care in many oncology facilities, but a fundamental question for navigator programs, especially in medically underserved populations, is whether or not individuals will use this service. In this study, we evaluated acceptance of a community-based navigator program for cancer control and identified factors having significant independent associations with navigation acceptance in an urban sample of African Americans. Participants were African American men and women ages 50-75 who were residents in an urban metropolitan city who were referred for navigation. Of 240 participants, 76% completed navigation. Age and perceived risk of developing cancer had a significant independent association with navigation acceptance. Participants who believed that they were at high risk for developing cancer had a lower likelihood of completing navigation compared with those who believed that they had a low risk for developing this disease. The likelihood of completing navigation increased with increases in age. None of the socioeconomic factors or health care variables had a significant association with navigation acceptance. There are few barriers to using community-based navigation for cancer control among urban African Americans. Continued efforts are needed to develop and implement community-based programs for cancer control that are easy to use and address the needs of medically underserved populations.

Background: Healthy dietary behaviors are critical strategies for cancer control. Despite this, many African Americans do not meet the recommended guidelines for fruit and vegetable intake. To develop effective cancer control interventions for African Americans, it is first necessary to understand within group variation in motivations for making dietary behavior changes and identify socioeconomic, social, and clinical factors that have significant independent associations with these motivations. Objectives: To characterize motivations for making dietary changes among African Americans and to identify socioeconomic, social, and clinical factors having significant independent associations with these intrinsic and extrinsic motivations among African American adults (n=530). Results: The mean (SD) level for intrinsic motivation was 26.5 (3.5) whereas the mean (SD) level for extrinsic motivation was 16.1 (4.8). Increasing age (Beta=0.03, p=0.03) and membership in at least one community organization (Beta=1.20, p=0.0003) had significant independent associations in the regression model for intrinsic motivation (n=479, F=5.97, p=0.0001). Lower incomes (Beta=-1.10, p=0.02) and age (Beta=0.06, p=0.006) had significant independent associations with extrinsic motivation. None of the clinical factors were associated significantly with intrinsic and extrinsic motivation. Conclusions: African Americans may be motivated to make dietary changes for cancer control because of intrinsic motivations. Different variables had significant independent associations with intrinsic and extrinsic motivations to make dietary changes among African Americans. It may be important to use alternative strategies to enhance these motivations as part of cancer control interventions that are developed for these individuals. Citation Format: Melanie S.
