Method: This descriptive, relational, and cross-sectional study was conducted between December 2022 and May 2023 in Siirt Training and Research Hospital, located in southeastern Türkiye, with the participation of 178 patients diagnosed with heart failure. The study data were collected through the Beliefs About Dietary Compliance Scale, the European Heart Failure Self-care Behavior Scale, the Life Satisfaction Scale, and a Patient Information Form. Results: The benefit and barrier perception subscale scores of the patients regarding dietary compliance were 23.51 ± 4.80 and 15.48 ± 4.12, respectively. The patients’ self-care behavior mean score was 37.76 ± 7.32, while their life satisfaction mean score was 16.46 ± 6.52. A negative and significant relationship was determined between the patients’ dietary compliance barrier perception subscale and their self-care behavior and life satisfaction mean scores (P < 0.05). Additionally, a positive and significant correlation was found between the patients’ self-care behavior and life satisfaction mean scores (P < 0.05). Conclusion: It was determined that the patients adopted dietary compliance benefit behaviors more and barrier behaviors less, indicating compliance with dietary treatment. It was observed that their self-care behaviors were inadequate, while their life satisfaction was at a moderate level. Furthermore, it was determined that as self-care behaviors and dietary compliance increased in patients, their life satisfaction also increased.eninfo:eu-repo/semantics/openAccessHeart Failure, Patient, Life Satisfaction, Self-Care Behavior, Dietary ComplianceArticle1538144151135261610.5543/khd.2024.22448
