Introduction: One of the nursing actions to overcome anxiety problems is to carry out therapeutic communication. With the existence of therapeutic communication, nurses can help clients and families understand better through verbal and non-verbal communication. However, there is often a gap between good communication theory and communication practice, leading to gaps in the field. The study wanted to determine the relationship between the nurse's therapeutic communication and the anxiety level of the patient's family experiencing emergency conditions.Methods: This study employed a cross-sectional and descriptive correlational research design with a sample size of 50 respondents using purposive sampling.Results: The results showed a relationship between nurses' therapeutic communication and the anxiety level of patients' families experiencing emergency conditions, with a p-value of 0.003. The results of this study indicated that most of the nurses' therapeutic communication was good (96%), and the patient's family anxiety level was mild (88%).Conclusion: Good therapeutic communication by nurses can reduce family anxiety.
