Aim:
This study aimed to develop a slogan poster designed to systematically inform individuals and encourage protective actions against Extreme Hot Weather Events (EHWE).
Methods:
A quasi-experimental single-group pretest-posttest design was employed, following the TREND guideline. EHWE knowledge was measured before exposure (Measurement 1), immediately after exposure (Measurement 2), and 2 months later (Measurement 3). Fifty-seven participants completed Measurements 1 and 2, and 45 completed all 3. Repeated-measures ANOVA and Bonferroni-adjusted pairwise comparisons were conducted; qualitative feedback was collected after Measurement 2.
Results:
Knowledge scores increased from Measurement 1 (M = 9.36, SD = 2.39) to Measurement 2 (M = 13.93, SD = 0.94), then decreased at Measurement 3 (M = 12.07, SD = 1.80), while remaining above baseline. ANOVA confirmed a significant effect of time (F[2.88] = 129.13, P < 0.001, partial η2 = 0.70). Feedback indicated clarity and practicality, with suggestions for design improvements.
Conclusion:
Poster exposure was associated with immediate knowledge gains, though a partial decline occurred by 2 months. Broader and controlled studies are needed to evaluate long-term effectiveness.
