Main Article Content
Abstract
Critical Health Literacy (CHL) is an advanced dimension of health literacy that enables individuals to critically evaluate health information and make informed health decisions. Despite growing scholarly attention, a comprehensive overview of global CHL research remains limited. This study aimed to analyze publication trends, influential contributors, collaboration networks, and thematic developments in CHL research through bibliometric analysis. A total of 179 open-access publications indexed in the Dimensions database between 2021 and 2025 were retrieved using the keyword “Critical Health Literacy” and screened according to the PRISMA 2020 guidelines. Bibliometric analyses were conducted using Biblioshiny and VOSviewer. The results indicated a steady increase in CHL publications, with 2025 recording the highest output (n = 58, 32.40%). Japan was the most productive country (n = 34), while Australia achieved the highest citation impact (398 citations). Norway demonstrated the strongest international collaboration network (Total Link Strength = 22). OsloMet – Oslo Metropolitan University emerged as the leading institution, contributing 9 publications and receiving 82 citations. Keyword co-occurrence analysis identified ten thematic clusters, highlighting major research areas including health decision-making, evidence-based practice, digital health literacy, measurement instruments, and patient empowerment. These findings provide insights into the intellectual structure and evolving research landscape of CHL and emphasize the importance of international collaboration in advancing health literacy research and evidence-based health promotion worldwide.
