The study aimed to develop and validate a new disease-specific instrument determining the factors affecting treatment adherence behaviors among patients receiving hemodialysis in a Sri Lankan hospital. The content validation process using a modified Delphi technique suggested 42-item instrument with an average Item-level Content Validity Index (I-CVI) of 0.94. Subsequent principal component analysis (PCA) revealed 5 components with 17 items (patient-centered psychological and physical factors, factors associated with health care, hemodialysis therapy-related factors, socioeconomic factors, and factors associated with the continuity of the treatment), explaining 67.24% total variance. The reliability estimate based on Mislevy and Bock for each component greater than 0.8 and overall standardized Cronbach's alpha of 0.605, indicated acceptable internal consistency reliability. Root mean square residual (RMSR) and weighted root mean square residual (WRMR) indices of 0.084 and 0.059, respectively, indicated acceptable model fit. The final 17-item instrument provides a valid measure for the factors affecting treatment adherence behaviors of the patients receiving hemodialysis in a Sri Lankan hospital.<\/jats:p>","DOI":"10.1177\/23743735231151558","type":"journal-article","created":{"date-parts":[[2023,1,27]],"date-time":"2023-01-27T00:18:35Z","timestamp":1674778715000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Psychometric Properties of an Instrument to Determine the Factors Affecting Treatment Adherence Among Patients Receiving Hemodialysis in Sri Lanka"],"prefix":"10.1177","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7891-8864","authenticated-orcid":false,"given":"Chalani","family":"Lasanthika","sequence":"first","affiliation":[{"name":"Faculty of Graduate Studies, University of Sri Jayewardenepura, Nugegoda, Sri Lanka"},{"name":"Department of Nursing and Midwifery, Faculty of Allied Health Sciences, University of Sri Jayewardenepura, Nugegoda, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kamani","family":"Wanigasuriya","sequence":"additional","affiliation":[{"name":"Center for Kidney Research, Faculty of Medical Sciences, University of Sri Jayewardenepura, Nugegoda, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Usha","family":"Hettiaratchi","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Medical Sciences, University of Sri Jayewardenepura, Nugegoda, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0191-0973","authenticated-orcid":false,"given":"Thamara Dilhani","family":"Amarasekara","sequence":"additional","affiliation":[{"name":"Department of Nursing and Midwifery, Faculty of Allied Health Sciences, University of Sri Jayewardenepura, Nugegoda, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christine Sampatha","family":"Evangeline Goonewardena","sequence":"additional","affiliation":[{"name":"Department of Community Medicine, Faculty of Medical Sciences, University of Sri Jayewardenepura, Nugegoda, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,1,26]]},"reference":[{"key":"bibr1-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfma.2021.12.013"},{"key":"bibr2-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1016\/j.ekir.2019.03.020"},{"key":"bibr3-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1186\/s12882-017-0598-2"},{"key":"bibr4-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1186\/2049-3258-72-37"},{"key":"bibr5-23743735231151558","volume-title":"Adherence to long-term therapies: evidence for action","author":"Sabat\u00e9 E","year":"2003"},{"key":"bibr6-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1097\/jnr.0000000000000309"},{"key":"bibr7-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1186\/s12882-022-02694-x"},{"key":"bibr8-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1016\/j.cegh.2018.05.003"},{"key":"bibr9-23743735231151558","doi-asserted-by":"publisher","DOI":"10.21767\/2471-299X.1000038"},{"key":"bibr10-23743735231151558","first-page":"1","volume":"9","author":"Panahi S","year":"2022","journal-title":"J Patient Exp"},{"key":"bibr11-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1080\/08870446.2012.703670"},{"key":"bibr12-23743735231151558","first-page":"1","volume":"8","author":"Banerjee A","year":"2021","journal-title":"J Patient Exp"},{"key":"bibr13-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1155\/2018\/4372716"},{"key":"bibr14-23743735231151558","doi-asserted-by":"publisher","DOI":"10.2174\/1874350101912010141"},{"key":"bibr15-23743735231151558","doi-asserted-by":"publisher","DOI":"10.3389\/fpubh.2018.00149"},{"key":"bibr16-23743735231151558","doi-asserted-by":"publisher","DOI":"10.3389\/fpubh.2017.00021"},{"key":"bibr17-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1177\/1937586719887709"},{"key":"bibr18-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1097\/00006199-198611000-00017"},{"key":"bibr19-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1111\/j.1744-6570.1975.tb01393.x"},{"key":"bibr20-23743735231151558","doi-asserted-by":"publisher","DOI":"10.15171\/jcs.2015.017"},{"key":"bibr21-23743735231151558","doi-asserted-by":"publisher","DOI":"10.1007\/s11136-014-0752-2"},{"key":"bibr22-23743735231151558","unstructured":"Principal Components Analysis (PCA) using SPSS Statistics [online]. 2018.
