Despite the increasing use of ECMO in T\u00fcrkiye, no comprehensive, validated tool exists to measure ICU nurses\u2019 self-efficacy in ECMO care. This methodological study aimed to develop the ECMO Nursing Self-Efficacy Perception Scale (ECMO-SEPS) and evaluate its psychometric properties. The scale was developed in two stages. In the first stage, an item pool was generated through an extensive literature review and qualitative interviews with seven ICU nurses experienced in ECMO care. In the second stage, the scale\u2019s content and construct validity were assessed using confirmatory factor analysis, including convergent and discriminant validity evaluations. Reliability analyses included internal consistency, evaluated by Cronbach\u2019s alpha coefficients, and test\u2013retest reliability, assessed with intraclass correlation coefficients. The final scale consists of 37 items across three subscales: cognitive, affective, and psychomotor, collectively explaining 70.5% of the total variance. Confirmatory factor analysis supported the three-factor structure with acceptable to good model fit indices. The overall Cronbach\u2019s alpha was 0.97, with 0.97, 0.81, and 0.96 for the cognitive, affective, and psychomotor subscales, respectively, indicating high internal consistency. Test\u2013retest results demonstrated excellent stability over time. In conclusion, the ECMO-SEPS is a valid and reliable instrument for objectively assessing ICU nurses\u2019 self-efficacy in ECMO care. Its use may facilitate standardized evaluations and inform evidence-based education, workforce planning, and clinical practice in ECMO programs.<\/jats:p>","DOI":"10.1177\/02676591261496709","type":"journal-article","created":{"date-parts":[[2026,10,10]],"date-time":"2026-10-10T08:10:26Z","timestamp":1791619826000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Development of the ECMO nursing self-efficacy Perception scale: A validity and reliability study"],"prefix":"10.1177","author":[{"given":"Sevil","family":"G\u00fcler","sequence":"first","affiliation":[{"name":"Gazi University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0256-2475","authenticated-orcid":false,"given":"Hafize","family":"Savas","sequence":"additional","affiliation":[{"name":"Lokman Hekim University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H\u00fclya","family":"Bulut","sequence":"additional","affiliation":[{"name":"Gazi University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0130smail","family":"Karakaya","sequence":"additional","affiliation":[{"name":"Gazi University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,10,10]]},"reference":[{"key":"e_1_3_9_2_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13019-017-0618-0"},{"key":"e_1_3_9_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2016.11.005"},{"issue":"1","key":"e_1_3_9_4_2","first-page":"224","article-title":"Application value of high-quality nursing in patients with severe pneumonia under the treatment of extra corporeal membrane oxygenation","volume":"13","author":"Li X","year":"2020","unstructured":"Li X, Zhou X, Zhang M.
