The aim of this study is to adapt the trauma-informed care scale, a scale developed to measure the level of knowledge, attitude and practice related to trauma-informed care, to Turkish culture by making the appropriate analysis. 161 mental health professionals participated in this survey model study. The data of the study were collected by using the convenience sampling method, the demographic information form and the Trauma Informed Care Scale. The data were generated through the online data collection platform surveey.com. It was determined that most of the mental health professionals (70.2%) in the study had never heard of the trauma-informed care model, and 87% did not use this model in their practice. The EFA analysis showed that a 3-factor structure was emerged, which explained 50.36% of the total variance and in which all items were included in the subscales of the original scale. According to the results of the analyzes, 3 items in the Attitude subscale were removed from the total items of the scale and the final version of 18 items scale that could be used in Turkish culture was created. The correlation analyzes showed that the total mean score was highly and positively correlated with all subscales. The Trauma-Informed Care Scale is a reliable measurement tool with proven structural validity and suitable for use by mental health professionals (physicians, nurses, psychologists, psychological counselors, social workers) working with trauma survivors, and researchers planning studies on trauma-informed care and/or trauma-sensitive care.
