Older adults aged \u2265 65 years were assigned by facility to either an intervention group (n = 66; four facilities) or a control group (n = 65; three facilities). The intervention group completed a 7-week program consisting of baseline assessment, five weekly group education sessions, individualized nutrition counseling, and post-intervention assessment. The control group received one general nutrition education session. Outcomes included dietary knowledge, outcome expectations, value expectations, self-efficacy, environmental factors (food accessibility and household food availability and social support), dietary behavior outcomes assessed using the Nutrition Quotient for the Elderly (NQ-E), and stage of change. Program effects were analyzed using ANCOVA adjusted for age, family composition, education, baseline dietary knowledge, and value expectations.Results: Compared with the control group, the intervention group demonstrated significantly greater improvements in dietary knowledge (P &lt; 0.001), outcome expectations (P = 0.018), self-efficacy (P &lt; 0.001), environmental factors (P &lt; 0.001), and NQ-E total score (P = 0.011). No significant between-group difference was observed for value expectations. The proportion of participants in the action stage increased from 9.1% to 93.9% in the intervention group, and post-intervention stage distribution differed significantly between groups (P &lt; 0.001). Program satisfaction was high (4.69 \u00b1 0.41).Conclusion: A 7-week nutrition intervention incorporating SCT-based personal and environmental constructs and TTM-based stage-matched counseling improved dietary behavior-related factors, dietary behavior outcomes, and stage distribution among community-dwelling older adults.<\/jats:p>","DOI":"10.5720\/kjcn.2026.00073","type":"journal-article","created":{"date-parts":[[2026,7,7]],"date-time":"2026-07-07T02:17:13Z","timestamp":1783390633000},"page":"264-275","update-policy":"https:\/\/doi.org\/10.5720\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect
