Objective: of this study was to determine the influence of health literacy on knowledge and attitudes.
Theoretical framework: Adolescents undergo significant biopsychosocial changes, making them vulnerable to engaging in negative activities such as alcohol consumption, risky behaviors, and drug use (Febrika, 2021). The rapid advancement of technology during adolescence also influences their risky behaviors. Therefore, adolescents require good health literacy to prevent such risky behaviors (Khairina et al., 2022). According to the Theory of Planned Behavior (TPB), adolescent behavior is influenced by attitudes and control beliefs, including internal control factors such as knowledge. Thus, to enhance adolescent health literacy, educational media like the snakes and ladders board game related to HIV/AIDS prevention is necessary (Ajzen, 1991).
Method: This research employed a quasi-experimental method with a one-group pretest-posttest design only, without a control group. Data were collected from 56 randomly selected respondents. The dependent variables were knowledge and attitudes, while the independent variable was the level of health literacy about HIV. Data analysis was performed using the Wilcoxon test.
Results and conclusion: Adolescents' knowledge before the intervention was 62.5% in the low category, and after the intervention, it increased to 91.1% in the high category. There was a significant relationship between health literacy about HIV using the snakes and ladders game board and knowledge (p=0.000). Before the intervention, 62.5% had a negative attitude, and after the intervention, 58.9% had a positive attitude (p=0.000). Conclusion: More health literacy about HIV among adolescents is needed.
