AimTo assess the effectiveness of a training program on perceptions of caring culture among Turkish nurses and investigate the relationships among caring culture, job satisfaction, and intention to leave.BackgroundEvery organisation has its on culture with its vairous components including values, symbols, practices and policies. Healthcare organizations need a favorable caring culture to support nurses and other professional working in the organisation.MethodsThis was a quasi‐experimental trial of an educational intervention conducted between October and December 2020 at a university hospital in Turkey. The sample of the study consisted of 86 nurses. A four‐week training program based on caring culture was provided for the training group. The data were collected using a Personal Information Form, the Turkish version of the Caring Culture Survey, and the Job Satisfaction Scale. Intention to leave was measured with a single question.FindingsThe mean total caring culture and personal caring scores of the training group were significantly higher after the training than before (p < 0.05). There were significant positive correlations between the mean caring culture total and subscale scores of the participants and their total job satisfaction scores. Besides, there were significant negative correlations between the caring culture total and subscale scores of the participants and their intentions to leave, but these relationships were weak or moderate (p < 0.05).ConclusionThis training program based on caring culture can contribute to improving the caring culture perceptions of nurses. Caring culture is positively related to job satisfaction and negatively related to intentions to leave.Implications for nursing and health policyHealthcare organizations should prioritize creating a caring culture and designing initiatives that focus on caring culture. The perceptions of nurses about caring culture should be measured and identified regularly.
