Between October 2004 and May 2005, we conducted 10 focus groups with African-American participants. To explore the range of perceptions regarding DFEs, and to preserve homogeneity within the groups and reduce possible response effects, participants were grouped by age and DFE status. We were particularly interested in the opinions of older African-Americans who had not had a recent DFE. Therefore, four focus groups were conducted with people 65 years of age and older who had not undergone a DFE in the past 2 years. Two focus groups were held with people 65 and older but who reported having had a DFE in the past 2 years. Two focus groups were held with African-Americans 40 to 64 years of age who had not received a DFE in the past 2 years and two groups were conducted with those 40 to 64 years of age but who reported having had a DFE in the past 2 years. Focus groups ranged in size from 5 to 11 participants. This research adhered to the tenets of the Declaration of Helsinki. We obtained Institutional Review Board approval for the study, and informed consent was obtained from all participants.
We recruited participants for the focus groups through print advertisements, radio announcements, flyers, and word of mouth. Interested people were screened for eligibility before assignment to the appropriate focus group. Potential participants were asked whether they were African-American and when they had their last dilated eye examination, with an explanation of a DFE provided. The focus group interviews were conducted at community sites that were easily accessible by the participants. Each focus group lasted from 1.5 to 2 hours, depending on the amount of participant discussion. Participants were paid $25 to compensate them for their time.
Two trained experienced moderators, one of whom was African-American, facilitated the sessions. To ensure comparability between sessions, the moderators used the same guide, the wording of which differed based on whether or not the people within the group had undergone a DFE within the past 2 years. The moderator guide included opening remarks about the focus group process, introductions by the participants, and information about eye exams. Topics addressed in the focus group discussions were rates of DFEs and reported eye problems, perceived barriers and benefits of getting an eye examination, motivators for getting DFEs, knowledge of eye examinations, glaucoma, and diabetic retinopathy, and physician communication.
Focus group sessions were tape recorded and a note taker served as a backup recorder for each session. Once data from focus groups was fully transcribed, two types of analysis were undertaken. Initially, basic categorical answers to specific inquiries were subjected to descriptive analysis. The second type of qualitative data analysis involved both areas of inquiry driven by specific research questions and those themes that emerged from participants’ own perspectives and conclusions. A codebook was constructed and the data were coded by thematic area and area of inquiry (Ethnograph data analysis software; Qualis Research Associates, Colorado Springs, CO).
26 At several points in the process, the data and codes were checked for consistency and to maintain objectivity. An audit trail was also carefully maintained throughout the analysis, to maximize reliability.

Data reduction was accomplished through a coded sort in the software, which identified key concepts within thematic and inquiry categories. These key concepts, which were derived from participant statements, were further reduced to form hypotheses that were then tested against rival hypotheses and through a search for disagreement.
27 28 Minimal disagreement was indicative of consensus among participants. Key concepts were finally presented in the reporting format through narrative and the use of participants’ statements. We examined focus group data by age groups and eye examination status, but use examples from the group as a whole to illustrate key concepts.
A brief questionnaire was completed by focus group participants before the start of the focus group discussions. Information about participant characteristics was collected, including age, gender, educational level, type of insurance, and income. Demographic variables were compared by eye examination status and age groups, using the Fisher exact test for the categorical variables and the t-test for mean age. Missing and “don’t know” responses were excluded from the analysis.
