Social Media Misinformation, Contraceptive Literacy, and Psychological Well-Being Among Romanian Adolescents and Young Adults

Background/Objectives: The rapid expansion of social media platforms has profoundly changed the way adolescents access reproductive health information. While digital environments increase accessibility to contraceptive content, they also facilitate the dissemination of misinformation, potentially influencing both contraceptive literacy and psychological well-being. The present study aimed to evaluate the relationship between sources of contraceptive information, contraceptive misinformation endorsement, contraceptive knowledge, and mental health indicators among Romanian adolescents and young adults. Methods: A cross-sectional observational study was conducted in a cohort of 210 Romanian adolescents and young adults. Participants completed a structured self-administered questionnaire assessing demographic characteristics, contraceptive information sources, digital health behaviors, contraceptive misconceptions, and contraceptive knowledge. Anxiety and depressive symptoms were evaluated using the Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) scales. Correlation analyses and multivariable logistic regression models were performed to identify factors associated with poor contraceptive knowledge and moderate-to-severe anxiety. Results: Social media represented the primary source of contraceptive information for 58.1% of participants. Individuals relying predominantly on social media demonstrated significantly lower contraceptive knowledge questionnaire (CKQ) scores compared to those obtaining information from healthcare professionals (5.9 ± 1.8 vs. 8.1 ± 1.7, p < 0.001). Contraceptive misinformation endorsement was inversely correlated with CKQ scores (r = −0.44, p < 0.001) and positively associated with anxiety (r = 0.47, p < 0.001) and depressive symptoms (r = 0.41, p < 0.001). In multivariable analyses, primary reliance on social media (OR 2.21, 95% CI 1.12–4.34, p = 0.022) and low digital health literacy (OR 2.94, 95% CI 1.51–5.71, p = 0.001) were independently associated with poor contraceptive knowledge. Higher misinformation endorsement, infertility-related fears, and high social media exposure were independently associated with moderate-to-severe anxiety. Conclusions: Contraceptive misinformation endorsement was associated with lower contraceptive literacy and poorer psychological outcomes among adolescents and young adults. These findings highlight the growing importance of digital health literacy. However, given the cross-sectional design, the observed relationships should be interpreted as associations rather than causal effects, and longitudinal studies are required to clarify their directionality.
