As many adolescents seek information online, providing reliable web-based resources may enhance their mental health literacy. This randomized experimental study (preregistered at ClinicalTrials.gov: NCT05300217) examined the effectiveness and reception of innovative online information designed to improve adolescents\u2019 knowledge of depression and mental health. A total of 77 adolescents aged 12\u201318 years were randomly assigned to one of two conditions: (1) web-based information on depression or (2) web-based information on strategies to promote mental health. Both interventions were derived from the evidence-based website \u201cich bin alles\u201d (English translation: \u201cI am everything\u201d). Primary outcomes were knowledge of depression and knowledge of strategies to promote mental health, assessed immediately after the intervention and at 2- and 4-week follow-ups. Secondary outcomes included perceived visual aesthetics, ease of use, utility, and enjoyment. Adolescents showed significant increases in knowledge of depression [\n                    <jats:italic>F<\/jats:italic>\n                    (3, 76.67)\u2009=\u200913.29,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&amp;lt;\u2009.001] and knowledge of strategies to promote mental health [\n                    <jats:italic>F<\/jats:italic>\n                    (3, 76.41)\u2009=\u20097.89,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&amp;lt;.001] over time, attributable to the assigned information. Participants also rated the website's visual aesthetics, ease of use, utility, and enjoyment positively. Age-appropriate, visually appealing web-based information effectively improved adolescents\u2019 knowledge of depression and mental health. Freely accessible, evidence-based online resources represent a scalable strategy to strengthen mental health literacy among young people.\n                  <\/jats:p>","DOI":"10.3389\/fdgth.2025.1640366","type":"journal-article","created":{"date-parts":[[2025,11,18]],"date-time":"2025-11-18T06:23:07Z","timestamp":1763446987000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Improving adolescents\u2019 knowledge about mental health and depression: a randomized experimental study of web-based information"],"prefix":"10.3389","volume":"7","author":[{"given":"Maria W.
