Combining behavior change theory with classification and regression tree (CART) is a novel data-driven approach to identifying barriers to self-monitoring. Baseline data from non-CGM-using patients in The GluCoCare Study were used to describe barriers to self-monitoring and use of data to inform diabetes self-care (\n                    <jats:italic toggle=\"yes\">N<\/jats:italic>\n                    \u2009=\u2009360). Patterns of barriers that predicted self-monitoring or use of self-monitoring data were also identified. Results showed barriers to self-monitoring were present in each of three Behavior Change Wheel categories: capability (e.g. procedural knowledge), opportunity (e.g. social support), and motivation (e.g. guilt). One example of a CART-identified pattern that predicted high self-monitoring was low guilt, high belief about importance of self-monitoring, low skin irritation, and high procedural knowledge. Future studies should test whether promoting these determinant patterns by addressing specific barriers leads to more self-monitoring and better outcomes.\n                  <\/jats:p>","DOI":"10.1177\/13591053261466351","type":"journal-article","created":{"date-parts":[[2026,8,5]],"date-time":"2026-08-05T02:47:52Z","timestamp":1785898072000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Classification and regression tree analysis to understand theory-aligned barriers to glucose self-monitoring behaviors among insulin-using type 2 diabetes patients without continuous glucose monitors"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5744-7215","authenticated-orcid":false,"given":"Meghan M.","family":"JaKa","sequence":"first","affiliation":[{"name":"HealthPartners Institute, Bloomington, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sally K.","family":"Gustafson","sequence":"additional","affiliation":[{"name":"HealthPartners Institute, Bloomington, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3154-824X","authenticated-orcid":false,"given":"Jennifer M.","family":"Dinh","sequence":"additional","affiliation":[{"name":"HealthPartners Institute, Bloomington, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mary L.","family":"Johnson","sequence":"additional","affiliation":[{"name":"HealthPartners Institute, Bloomington, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steve E.","family":"Asche","sequence":"additional","affiliation":[{"name":"HealthPartners Institute, Bloomington, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sean","family":"Dunnigan","sequence":"additional","affiliation":[{"name":"HealthPartners Institute, Bloomington, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8164-8858","authenticated-orcid":false,"given":"Michael V.","family":"Maciosek","sequence":"additional","affiliation":[{"name":"HealthPartners Institute, Bloomington, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeanette Y.","family":"Ziegenfuss","sequence":"additional","affiliation":[{"name":"HealthPartners Institute, Bloomington, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alyse L.","family":"Haven","sequence":"additional","affiliation":[{"name":"HealthPartners Institute, Bloomington, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard M.","family":"Bergenstal","sequence":"additional","affiliation":[{"name":"HealthPartners Institute, Bloomington, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas W.","family":"Martens","sequence":"additional","affiliation":[{"name":"HealthPartners Institute, Bloomington, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,8,4]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"crossref","unstructured":"Adu MD Malabu UH Malau-Aduli AEO et al.
