While social support is a traditional focus of care, internal psychological resources may be more critical for sustaining treatment adherence in isolated therapeutic settings.\nObjective: To determine the prevalence of self-care behaviors and evaluate the extent to which health literacy and self-efficacy predict these behaviors among patients with HMs in northeastern Thailand.\nMethods: This multicenter, cross-sectional study, conducted from August to December 2025, utilized convenience sampling to recruit 350 patients with HMs from three tertiary hospitals in northeastern Thailand. Data were collected via self-administered questionnaires and analyzed using descriptive statistics and binary logistic regression. The predictive model\u2019s performance was evaluated using the Area Under the Curve (AUC), with significance set at p &lt; 0.05.\nResults: The prevalence of high self-care behaviors was 61.2% (95% CI = 55.8-66.3). Bivariable analysis showed that social support was initially associated with higher self-care. However, binary logistic regression identified only health literacy (AOR = 18.05, 95% CI = 14.40-20.10) and self-efficacy (AOR = 10.79, 95%CI = 5.70-11.40) as significant independent predictors. Social support did not remain a significant predictor in the final model. The model exhibited excellent discriminant ability with an AUC of 0.86 (95% CI = 0.78-0.91, p &lt; 0.001).\nConclusion: High self-care behaviors are common among patients with HMs in northeastern Thailand. Our results show that internal factors, specifically health literacy and self-efficacy, are stronger predictors of self-care than external social support in this treatment-intensive context. These findings underscore the need for oncology nurses to screen for both health literacy and self-efficacy during clinical assessments, enabling early identification of at-risk patients and delivery of targeted interventions to promote effective self-management.<\/jats:p>","DOI":"10.33546\/bnj.4641","type":"journal-article","created":{"date-parts":[[2026,10,21]],"date-time":"2026-10-21T05:54:58Z","timestamp":1792562098000},"page":"632-642","update-policy":"https:\/\/doi.org\/10.33546\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Health literacy and self-efficacy as predictors of self-care behaviors in patients with hematological malignancies: A multicenter cross-sectional study in northeastern Thailand"],"prefix":"10.33546","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9557-2199","authenticated-orcid":false,"given":"Ueamporn","family":"Summart","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monthida","family":"Sangruangake","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chanathip","family":"Halak","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Phawadee Thongnopkhun","family":"Toyn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"19163","published-online":{"date-parts":[[2026,10,21]]},"reference":[{"key":"162512","doi-asserted-by":"crossref","unstructured":"Abu El-Kass, S. d., Ragheb, M.
