Particularly concerning the treatment of cancer, this can pose risks, especially when it leads to delay or replacement of evidence\u2010based treatments. The goal was to assess informed decision\u2010making and analyze outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The decision aid summarized key aspects of homeopathy, including its definition, distinction from naturopathy, production, approval, scientific evidence, placebo effects, use in cancer, side effects, and insurance coverage. Therefore, we conducted a single arm,\u00a0pre\u2010post observational survey. A questionnaire assessed knowledge, attitudes, and use of homeopathy before and after reading the aid. It included demographic data, topic\u2010specific knowledge, use for certain medical conditions, and an evaluation section. A total of 123 adult cancer patients were recruited from oncology centers across Germany (2022), with no age restrictions. Changes in knowledge and attitudes were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Participants significantly revised their views on homeopathy for most medical conditions; beliefs about its use for psychological stress remained unchanged. Knowledge about placebo effects and potentization improved significantly, whereas understanding of side effects did not. Prior use of homeopathy influenced post\u2010intervention decisions. Educational background and socioeconomic status showed no significant effects, demonstrating broad applicability of the intervention. Ordinal regression analyzes indicated that participants with lower prior knowledge benefited more, particularly regarding \u201cpotentization\u201d and \u201cplacebo difference.\u201d Post\u2010intervention knowledge gains varied by prior knowledge and gender, with less\u2010informed participants and male respondents benefiting more. Most participants felt well informed, gained new insights, and would recommend the material.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The decision aid demonstrated potential to support evidence\u2010based decision\u2010making among oncology patients.<\/jats:p>\n                    <jats:p>However, heterogeneity in outcomes indicates the influence of unmeasured factors, such as belief systems or emotional needs.<\/jats:p>\n                    <jats:p>Future research should explore tailoring decision aids to gender\u2010 and knowledge\u2010levels.
