Aim: To describe probiotic knowledge; its relationship with probiotic use, probiotic information sources and factors influencing choice in adults with CF and a general population control group. Methods: A cross-sectional questionnaire study was conducted in adults with CF (n\u2009=\u2009205) and Controls (n\u2009=\u2009158). Probiotic knowledge was compared between CF and Controls using a knowledge score (maximum 5) based on predefined criteria: (1a) bacteria\/microorganism; (1b) live; (2a) administered; (2b) adequate dose and (3) health benefit, using independent samples t-test. Two-way analysis of variance explored knowledge scores between CF and Control and between Ever User and Never User groups. Chi-square and Fisher's exact tests compared knowledge criterion, probiotic sources and influences on probiotic choice between groups. Thematic analysis of open-text responses explored probiotic-related knowledge and influences on probiotic decision making. Results: Knowledge scores (mean\u2009\u00b1\u2009SD) did not differ between CF (1.70\u2009\u00b1\u20091.12) and Controls (1.89\u2009\u00b1\u20090.99), p\u2009=\u20090.13. Probiotic use was associated with knowledge score ( p\u2009&lt;\u20090.001). More CF Ever Users than Never Users correctly identified criteria 1a (65% vs. 38%), 1b (16% vs. 0%), 2a (45% vs. 22%) and 3 (73% vs. 42%) (all p\u2009&lt;\u20090.005). CF participants considered \u2018dairy yoghurt\u2019 (69%), \u2018live cultures\u2019 (64%) and \u2018fermented foods\u2019 (37%) as \u2018all\/mostly\u2019 probiotic sources. The internet was the commonest source of probiotic-related information. Conclusion: Probiotic knowledge and use were associated in adults with CF. Understanding of probiotic characteristics and sources were limited. Education is needed to help guide patient probiotic decision making.<\/jats:p>","DOI":"10.1177\/02601060221136653","type":"journal-article","created":{"date-parts":[[2022,11,11]],"date-time":"2022-11-11T02:21:52Z","timestamp":1668133312000},"page":"697-706","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Probiotic
