The purpose of this study was to enhance retention among African American men enrolled in a cancer screening trial.
A telephone-based, randomized trial design was used. The intervention group included 352 African American men aged 55+. Case managers contacted participants at least monthly and provided information and referral services to participants and their relatives.
The mean age of participants was 65.7 years. A total of 14,978 calls were made resulting in 780 referrals. The 10 most frequent referrals were for scheduling medical appointments, health information, insurance information, legal aid, transportation, cancer screening information, information technology/computer information, employment, housekeeping/chore services, and food programs.
The case managers served as links between participants and community-based resources. The types of referrals made could be associated with the age-related needs of the participants.

- "The JHS Community Partnership office developed successful strategies in working with African Americans in research by emphasizing local access, local relevance, and decision-making . Activities had to be implemented to enhance retention among the African American population, providing information to the participants and their relatives, and serving as links between the participant and other community resources , especially since a significant barrier to participation in research is mistrust of the scientific community and institutions .

ABSTRACT: The public health burden caused by cardiovascular disease (CVD) continues to adversely affect individuals in terms of cost, life expectancy, medical, pharmaceutical and hospital care. This burden has been excessive in the case of African Americans. The objective of this paper is to chronicle the procedures and processes that were implemented in the development of the Jackson Heart Study Coordinating Center. The Jackson Heart Study (JHS) is a population-based investigation of traditional and emerging risk factors that predict progression to CVD among African Americans. In response to the struggle against CVD, the Jackson Heart Study has convened a professional, technical, and administrative staff with specific competence in the operation of a coordinating center to handle the wide variety of areas related to CVD studies. The Jackson Heart Study Coordinating Center (JHSCC) was created to assure validity of the JHS findings and provide the resources necessary to meet comprehensive statistical needs (planning, implementing and monitoring data analysis); data management (designing, implementing and managing data collection and quality control), and administrative support. The JHSCC began with a commitment to support study functions in order to increase participant recruitment, retention and safety, meet regulatory requirements, prepare progress reports, and facilitate effective communication with the community and between all JHS centers. The JHSCC facilitates the efforts of the JHS scientists through the development and implementation of the study protocol. The efforts of the JHSCC have resulted in the successful preparation of scientific reports and manuscripts for publication and presentation of study findings and results. In summary, the JHSCC has emerged as an effective research mechanism that serves as the driving force behind the Jackson Heart Study activities.

ABSTRACT: The purpose of this study was to enhance adherence among older (aged 55 years and older) African American men enrolled in a cancer screening trial for prostate, lung, and colorectal cancer. For this study, we defined adherence as completing the trial screenings.
We used a randomized trial design. Case managers contacted intervention group participants (n=352) at least monthly by telephone and provided information and referral services. The control group included 351 participants.
Among participants with low income, those in the intervention group had higher screening adherence rates than did participants in the control group for (a) prostate-specific antigen test for prostate cancer (74.3% vs 53.0%, p=.001), (b) digital rectal exam for prostate cancer (66.2% vs 46.1%, p=.011), and (c) chest x-ray for lung cancer (70.9% vs 51.3%, p=.012). We found no statistically significant differences in adherence rates for flexible sigmoidoscopy screening for colorectal cancer. In contrast, among participants with moderate-to-high income, we found no statistically significant differences in adherence rates between intervention and control group participants for any of the screening tests.
The case management intervention was effective in enhancing adherence among participants with the lowest income, who in many studies are the most difficult to retain.

ABSTRACT: This article compares the recruitment costs and participant characteristics associated with the use of probability and nonprobability sampling strategies in a longitudinal study of older hemodialysis patients and their spouses. Contrasts were made of people who accrued to the study based on probability and nonprobability sampling strategies. Probability-based sampling was more time-efficient and cost-effective than nonprobability sampling. There were no significant differences between the respondents identified through probability and nonprobability sampling on age, gender, years married, education, work status, and professional job status. Respondents from the probability sample were more likely to be Protestant and less likely to be Catholic than those from the nonprobability sample. Respondents from the probability sample were more likely to be Black, whereas those from the nonprobability sample were more likely to be White. There are strengths and shortcomings associated with both nonprobability and probability sampling. Researchers need to consider representativeness and external validity issues when designing sampling and related recruitment plans for health-related research.
