Greater illness acceptance has been associated with better psychological adjustment, improved coping, and enhanced wellbeing among individuals living with chronic conditions. The Acceptance of Illness Scale (AIS) is widely used to assess individuals\u2019 psychological adaptation to chronic disease. However, a validated Sinhala version has not been available, limiting its use in Sri Lanka. This study aimed to culturally adapt and evaluate the psychometric properties of the Sinhala version of the AIS among individuals living with chronic illnesses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The original AIS was translated into Sinhalese using the back-translation process. Data were collected from 141 adults (63.1% women) who self-identified as people with chronic diseases, spoke Sinhala, and were living in Sri Lanka. Principal component analysis (PCA) and confirmatory factor analysis (CFA) were conducted to evaluate the scale\u2019s dimensional structure. Cronbach\u2019s \u03b1 was used to assess internal consistency, and r Pearson correlations with measures of life satisfaction and depression were employed to examine convergent validity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The Sinhala AIS demonstrated satisfactory internal consistency (Cronbach\u2019s \u03b1 = 0.75). PCA supported a single-component structure consistent with the original version, explaining 52.66% of the total variance. Subsequent CFA conducted on the same sample provided partial support for the one-factor structure (CFI = 0.99, AGFI = 0.97, TLI = 0.99, SRMR = 0.06, RMSEA = 0.097). Acceptance of illness was positively correlated with life satisfaction (\n                      <jats:italic>r<\/jats:italic>\n                      = 0.253) and negatively correlated with depression (\n                      <jats:italic>r<\/jats:italic>\n                      = \u22120.336), providing preliminary evidence for construct validity.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The findings provide preliminary support for the reliability and construct validity of the Sinhala AIS among Sinhala-speaking adults with chronic diseases and encourage further research on its psychometric properties and applicability in diverse clinical populations. The scale may be a useful tool for research and potentially for clinical applications; however, further validation is recommended.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyg.2026.1889860","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T05:50:08Z","timestamp":1790142608000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Adapting the acceptance of illness scale for Sinhala-speaking populations: a psychometric study"],"prefix":"10.3389","volume":"17","author":[{"given":"Darshika Thejani","family":"Bulathwatta","sequence":"first","affiliation":[{"name":"Department of Psychology and Counseling, Faculty of Health Sciences, The Open University of Sri Lanka","place":["Colombo, Sri Lanka"]},{"name":"Institute of Psychology, Faculty of Social Sciences, University of Gda\u0144sk","place":["Gda\u0144sk, Poland"]},{"name":"Academic Center for Psychological Support, University of Gda\u0144sk","place":["Gda\u0144sk, Poland"]},{"name":"Institute of Pedagogy and Languages, University of Applied Sciences in Elbl\u0105g","place":["Elbl\u0105g, Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Judyta","family":"Borchet","sequence":"additional","affiliation":[{"name":"Institute of Psychology, Faculty of Social Sciences, University of Gda\u0144sk","place":["Gda\u0144sk, Poland"]},{"name":"Institute of Pedagogy and Languages, University of Applied Sciences in Elbl\u0105g","place":["Elbl\u0105g, Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asanka","family":"Bulathwatta","sequence":"additional","affiliation":[{"name":"Department of Psychology, Faculty of Arts, University of Peradeniya","place":["Peradeniya, Sri Lanka"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monika","family":"Bidzan-Wi\u0105cek","sequence":"additional","affiliation":[{"name":"Institute of Psychology, University College of Professional Education","place":["Wroc\u0142aw, Poland"]},{"name":"Division of Quality of Life Research, Faculty of Health Sciences with the Institute of Maritime and Tropical Medicine, Medical University of Gda\u0144sk","place":["Gda\u0144sk, Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Mueller-Haugk","sequence":"additional","affiliation":[{"name":"Duale Hochschule Sachsen, Standort Plauen","place":["Plauen, Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilona","family":"Bidzan-Bluma","sequence":"additional","affiliation":[{"name":"Institute of Psychology, Faculty of Social Sciences, University of Gda\u0144sk","place":["Gda\u0144sk, Poland"]},{"name":"Institute of Pedagogy and Languages, University of Applied Sciences in Elbl\u0105g","place":["Elbl\u0105g, Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcus","family":"Stueck","sequence":"additional","affiliation":[{"name":"International Biocentric Research Academy","place":["Leipzig, Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariola","family":"Bidzan","sequence":"additional","affiliation":[{"name":"Institute of Psychology, Faculty of Social Sciences, University of Gda\u0144sk","place":["Gda\u0144sk, Poland"]},{"name":"Institute of Pedagogy and Languages, University of Applied Sciences in Elbl\u0105g","place":["Elbl\u0105g, Poland"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,23]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"e0000399","DOI":"10.1371\/journal.pgph.0000399","article-title":"Epidemiological and virological factors determining dengue transmission in Sri Lanka during the COVID-19 pandemic.","volume":"2","author":"Ariyaratne","year":"2022","journal-title":"PLoS Glob.
