Objective:
To evaluate the effectiveness of an educational program (INTI) on knowledge, attitudes, and photoprotection habits among adolescents exposed to high levels of ultraviolet (UV) radiation in a high-altitude rural area of Peru.
Study Design:
Quasi-experimental. Pretest-posttest study with non-randomized control and experimental groups.
Methods:
The study included 37 third-year secondary school students from a public school in the Andean region of Peru, who were assigned to a control group (n = 18) or an experimental group (n = 19) that received the 12-session INTI educational program. Knowledge, habits, and attitudes toward photoprotection were assessed before and after the intervention using the CHACES questionnaire. Between-group differences in posttest scores were examined using analysis of covariance (ANCOVA), adjusting for pretest score.
Results:
Pretest scores were similar between groups. At posttest, the experimental group showed higher mean scores than the control group in knowledge (M = 6.58; M = 5.89), habits (M = 12.7; M = 10.4), and attitudes (M = 33.2; M = 30.1). Analysis of covariance (ANCOVA) showed statistically significant between-group differences in knowledge (p = 0.033), habits (p < 0.001), and attitudes (p = 0.019) after adjusting for baseline scores.
Conclusions:
The study demonstrated that the INTI program significantly improved posttest scores for knowledge, habits, and attitudes related to photoprotection in the experimental group compared with the control group.
