M. Dignan et al., EFFECTIVENESS OF HEALTH-EDUCATION TO INCREASE SCREENING FOR CERVICAL-CANCER AMONG EASTERN-BAND CHEROKEE INDIAN WOMEN IN NORTH-CAROLINA, Journal of the National Cancer Institute, 88(22), 1996, pp. 1670-1676
Background: The North Carolina Native American Cervical Cancer Prevent
ion Project was a 5-year, National Cancer Institute-funded trial of he
alth education designed to increase screening for cervical cancer amon
g Native-American women in North Carolina. Purpose: This study was con
ducted to evaluate the effectiveness of this education program in the
Eastern-Band Cherokee target population. Methods: Cherokee tribal land
s were mapped and all households (N = 2223) were listed to ensure maxi
mum coverage of the eligible population (women, aged 18 years and olde
r, who were enrolled tribal members). Eligible women were identified b
y the use of a brief questionnaire administered to an adult member of
the household. Of the 1279 households with eligible women, 1020 (79.8%
) agreed to participate. The intervention was an individualized health
education program delivered by female Cherokee lag health educators.
The participants were randomly assigned to receive or not to receive t
he intervention (i.e., to program and control groups, respectively) by
use of the Solomon Four-Group design. Data were collected in face-to-
face interviews conducted in the participant's home. Of the 996 women
who were ultimately enrolled, 540 were randomly assigned to receive a
pretest (preintervention) interview that involved administration of a
96-item questionnaire designed to collect data on knowledge, intention
s, and behaviors related to cervical cancer; of these 540 women, 263 w
ere randomly assigned to receive the education program. The remaining
456 women did not receive the pretest, but 218 were randomly assigned
to receive the education program. Six months after receiving the educa
tion program, the women in all four groups were administered a post-te
st that was identical to the pretest. Logistic regression was used to
assess the effects of the pretest and the educational program. All P v
alues resulted from two-sided statistical tests. Results: Eight hundre
d and fifteen (81.8%) of the 996 participants completed the post-test
interview. The remaining 181 women who were lost to follow-up were eve
nly distributed among the four study groups. At the post-test, 282 (73
.2%) of the 385 women who received the education program reported havi
ng had a Pap smear following the intervention, compared with 275 (64%)
of the 430 control subjects. Women who received the education program
were more likely to answer all knowledge items correctly on the post-
test (odds ratio [OR] = 2.18, 95% confidence interval [CI] = 1.08-4.39
) and to report having obtained a Pap smear in the past year (OR = 2.0
6, 95% CI = 1.14-3.72) than women in the control groups. Conclusion: W
omen who received the education program exhibited a greater knowledge
about cervical cancer prevention and were more likely to have reported
having had a Pap smear within the past year than women who did not re
ceive the program.
