All the coefficients are statistically significant at the level of p < 0.05 except the coefficients in bold, which are only statistically significant at the level of p < 0.10. E, exposure to contradictory messages regarding the HPV vaccine on social media. SMDN, descriptive norms on social media; SMIN, injunctive norms on social media; AT, attitudes toward HPV vaccination; BI, behavioral intentions to receive the HPV vaccine.
