However, participation remains suboptimal because of multiple individual, sociocultural, and structural barriers, including limited knowledge, stigma, cultural and religious beliefs, healthcare accessibility, and socioeconomic constraints. This multi-site three-arm randomized controlled trial evaluated the effectiveness of digital leaflet-based, educational video-based, and face-to-face genetic counseling on knowledge, attitudes, and screening intentions among prospective couples in Ciamis District, Indonesia. A total of 177 prospective couples were randomized (digital leaflet = 59, video = 59, face-to-face = 59). After follow-up, 41, 53, and 59 participants, respectively, completed the post-intervention assessment and were included in the final analysis. Outcomes were measured at baseline and post-intervention using validated questionnaires and analyzed using Wilcoxon signed-rank tests and repeated-measures analysis of variance. Digital leaflet-based counseling significantly improved knowledge and screening intention (p &lt; 0.001), while educational video-based counseling significantly improved knowledge, attitudes, and intention (p &lt; 0.05). Face-to-face counseling showed no statistically significant changes across outcomes. Between-group analyses revealed significant differences in knowledge (\u03b72 = 0.059, p &lt; 0.001), attitudes (\u03b72 = 0.080, p &lt; 0.001), and intentions (\u03b72 = 0.084, p &lt; 0.001), with digital interventions outperforming face-to-face counseling. These findings suggest that digital genetic counseling modalities were associated with greater improvements in knowledge, attitudes, and premarital screening intentions than face-to-face counseling in this study setting.<\/jats:p>","DOI":"10.3390\/ijerph23070914","type":"journal-article","created":{"date-parts":[[2026,7,17]],"date-time":"2026-07-17T05:32:17Z","timestamp":1784266337000},"page":"914","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effectiveness of Genetic Counseling Modalities on Knowledge, Attitudes, and Premarital Screening Intentions for Thalassemia Prevention: A Multi-Site Three-Arm Randomized Controlled Trial"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9252-6277","authenticated-orcid":false,"given":"Henri","family":"Setiawan","sequence":"first","affiliation":[{"name":"Faculty of Medicine and Health, Institut Teknologi Sepuluh Nopember, Surabaya 60111, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9282-0345","authenticated-orcid":false,"given":"Chengyang","family":"Li","sequence":"additional","affiliation":[{"name":"School of Nursing, Fujian Medical University, Fuzhou 350005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9449-4264","authenticated-orcid":false,"given":"Muhammad Kamil Che","family":"Hasan","sequence":"additional","affiliation":[{"name":"Kulliyyah of Nursing, International Islamic University Malaysia, Kuantan 25200, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3977-0470","authenticated-orcid":false,"given":"Thandar Soe @ Sumaiyah","family":"Jamaludin","sequence":"additional","affiliation":[{"name":"Kulliyyah of Nursing, International Islamic University Malaysia, Kuantan 25200, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5440-3476","authenticated-orcid":false,"given":"Yudisa Diaz Lutfi","family":"Sandi","sequence":"additional","affiliation":[{"name":"Department of Nursing, Politeknik Negeri Subang, Subang 41285, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1191-0056","authenticated-orcid":false,"given":"Andan","family":"Firmansyah","sequence":"additional","affiliation":[{"name":"Department of Nursing, STIKes Muhammadiyah Ciamis, Ciamis 46216, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-5093-1378","authenticated-orcid":false,"given":"Yuyun","family":"Rahayu","sequence":"additional","affiliation":[{"name":"Department of Nursing, STIKes Muhammadiyah Ciamis, Ciamis 46216, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9023-4200","authenticated-orcid":false,"given":"Ima","family":"Sukmawati","sequence":"additional","affiliation":[{"name":"Department of Nursing, STIKes Muhammadiyah Ciamis, Ciamis 46216, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-2834-0718","authenticated-orcid":false,"given":"Lilis","family":"Lismayanti","sequence":"additional","affiliation":[{"name":"Department of Nursing, STIKes Muhammadiyah Ciamis, Ciamis 46216, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6903-3407","authenticated-orcid":false,"given":"Edwin Nugroho","family":"Njoto","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health, Institut Teknologi Sepuluh Nopember, Surabaya 60111, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Saleem, M., Aslam, W., Lali, M.I.U., Rauf, H.T., and Nasr, E.A.
