Eight participants were lost to follow-up; however, all 76 participants (38 per group) were included in the primary analysis using all available observations. The intervention was based on Pengjuntr\u2019s V-shape HL model, which includes six domains: access, understanding, interactive communication, decision-making, behavior change, and advocacy. The program was delivered through group sessions, LINE-based communication, community activities, and home visits. Data were collected at pre-test (baseline), post-test (4 weeks), and follow-up (12 weeks) using questionnaires. Outcomes were analyzed using linear mixed-effects models. This study was retrospectively registered with the Thai Clinical Trials Registry (TCTR20260502013).Results: At post-test, the experimental group had significantly higher COVID-19 awareness and preventive behavior scores than the control group (p&lt;.001). Within-group analysis showed significant improvements in both COVID-19 awareness and preventive behavior at post-test and follow-up. Significant between-group differences were also observed at follow-up (p&lt;.001), with higher scores in the experimental group.Conclusion: The intervention group receiving the HL enhancement program showed significant improvements in both COVID-19 awareness and preventive behaviors, which were sustained through follow-up. These findings support the use of nurse-led, community-based HL interventions with behavioral reinforcement to promote COVID-19 prevention among urban older adults.<\/jats:p>","DOI":"10.4040\/jkan.25147","type":"journal-article","created":{"date-parts":[[2026,7,28]],"date-time":"2026-07-28T05:56:28Z","timestamp":1785218188000},"page":"306-317","update-policy":"https:\/\/doi.org\/10.4040\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of a health literacy program on COVID-19 awareness and preventive behaviors among older adults in Bangkok, Thailand: a quasi-experimental study"],"prefix":"10.4040","volume":"56","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-8802-5443","authenticated-orcid":true,"given":"Walaya","family":"Tupanich","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-0329-0950","authenticated-orcid":true,"given":"Sasawan","family":"Attaworakun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-5489-7035","authenticated-orcid":true,"given":"Suteekarn","family":"Chaiyalap","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-0532-6628","authenticated-orcid":true,"given":"Nattanan","family":"Wattanawikan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2474","reference":[{"key":"ref1","volume-title":"Strengthening Preparedness for COVID-19 in cities and urban settings [Internet]","year":"2020"},{"key":"ref2","volume-title":"Thailand COVID-19 situation: report 231 [Internet]","year":"2022"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.mm7205a1"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-020-09826-8"},{"key":"ref5","volume-title":"The impact of COVID-19 on older persons in Thailand [Internet]","year":"2020"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-025-85324-4"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.7150\/ijbs.45221"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/S2468-2667(20)30086-4"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.7326\/M20-1239"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1093\/heapro\/15.3.259"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2458-12-80"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph17155503"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1177\/0951484817733366"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-018-6331-7"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.4235\/agmr.21.0090"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.14456\/jhr.2016.43"},{"key":"ref17","first-page":"1","volume-title":"Development of a V-shape model for strengthening health literacy in Thai communities","author":"Pengjuntr","year":"2017"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1177\/1090198104263660"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1186\/1748-5908-6-42"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.2105\/ajph.94.3.361"},{"key":"ref21","volume-title":"Effects of a long COVID literacy enhancement program on reducing the severity of post-infection COVID-19 behaviors of elderly in communities, Bangkok metropolitan area.
