Summary
This study successfully recruited diverse working-class individuals for cancer prevention trials. Findings provide crucial data on recruitment methods and intraclass correlation coefficients for future research.
Area of Science:
- Public Health
- Health Disparities
- Cancer Prevention Research
Background:
- Recruiting diverse populations for health interventions presents unique challenges.
- Few studies address recruitment for cancer prevention in multiracial, multiethnic, working-class groups.
- This paper details recruitment strategies for two group-randomized intervention studies.
Purpose of the Study:
- To report on sample selection and survey methods for two group-randomized intervention studies.
- To assess the feasibility of recruiting multiracial and multiethnic working-class participants.
- To provide data on recruitment outcomes and intraclass correlation coefficients (ICCs).
Main Methods:
- Two group-randomized intervention studies were conducted: Healthy Directions-Small Business (HD-SB) and Healthy Directions-Health Centers (HD-HC).
- HD-SB involved worksite-based recruitment in 26 small manufacturing businesses.
- HD-HC involved recruitment in 10 outpatient health centers, assessing sociodemographic and behavioral outcomes via self-report.
Main Results:
- The HD-SB study included 1740 participants (68% non-Hispanic white, 76% working-class).
- The HD-HC study included 2219 participants (59% non-Hispanic white, 51% working-class among employed).
- High percentages in both samples did not meet guidelines for target behaviors (e.g., 86% consumed <5 servings of fruits/vegetables daily).
- Intraclass correlation coefficients (ICCs) for target behaviors were low, ranging from 0.0004 to 0.02.
Conclusions:
- Both studies successfully recruited multiracial and multiethnic working-class participants.
- The recruitment methods employed were effective for the target population.
- The reported outcome estimates and ICCs are valuable for planning future cancer prevention studies.

01:13Randomized Experiments
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

01:16Stratified Sampling Method
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.

02:55Stereotypes, Prejudice, and Discrimination
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who are...
02:01Group Design
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between the two are due to...
01:20Comparing the Survival Analysis of Two or More Groups
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and Cox...
01:29Bias in Epidemiological Studies
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
