IntroductionsThe aim of this study was to demonstrate the impact of individualized nursing care on patient satisfaction and trust in nurses through structural equation modelling in patients receiving treatment in internal clinics.MethodsThe study is a descriptive, exploratory and cross‐sectional research conducted with patients receiving treatment in the internal admission services of an educational research hospital between January and April 2023. According to sample calculations, it was determined that a minimum of 238 patients needed to be included in the study, and 286 patients who met the inclusion criteria and agreed to participate in the research formed the study sample. Data were collected using the ‘Patient Identification Form’, ‘Individualized Care Scale‐Patient Version’, ‘Newcastle Nursing Care Satisfaction Scale’ and the ‘Trust in Nurses Scale’.ResultsThe level of awareness of nursing actions supporting individuality was found to be 2.71 ± 0.99, the level of perceiving individuality was 2.88 ± 0.99, the average level of nursing care satisfaction measured 77.17 ± 12.67 and the average level of trust in nurses was 21.92 ± 3.04. It was determined that as patients' awareness of nursing actions supporting individuality and their perception of individuality in care increased, they remained more satisfied with their care and had greater trust in nurses.ConclusionsPatients who perceived receiving individualized care were found to have higher levels of patient satisfaction and trust in nurses. Additionally, it was observed that as participants' satisfaction with their care increased, their trust in nurses also increased.
