Abstract:

The objective was to evaluate adolescents' knowledge of contraceptive methods before and after an educational intervention using a comic book. This quasi-experimental study was conducted from September to October 2023, with 62 high school adolescents from Maceió, AL. Knowledge about contraceptive methods was assessed at four different points in time. The Friedman, Wilcoxon, and McNemar tests were used for analysis. The median knowledge score was 8 (p25-p75; 4-12) at the pretest, 14 (p25-p75; 5-15) at the immediate posttest, 13 (p25-p75; 5-15) at the 7-day posttest, and 13 (p25-p75; 6-15) at the 15-day posttest. Adolescents' knowledge at the three post-intervention assessments was significantly higher than at the pre-test (<0.001). When comparing post-test scores, no change was found between the immediate post-test and the seven-day post-test (p=0.108), between the immediate post-test and the 15-day post-test (p=0.262), and between the seven-day post-test and the 15-day post-test (p=0.442). Knowledge scores were maintained up to 15 days after the intervention. The comic book "Methods of contraception: I'm young and I don't want to have a baby yet" is a resource with potential to increase adolescents' knowledge about contraceptive use.
