Abstract(s)

Introduction: The therapeutic relationship (TR) is essential to providing psychiatric and mental health nursing care. Nevertheless, no assessment tools exclusive for assessing nursing TR were found in the literature. Aim: To describe and evaluate the psychometric properties (reliability and construct validity) of a scale that allows assessing the quality of TR established between the nurse and the patient. Method: A survey method was adopted, using a convenience sample of 356 mental health nurses. Internal consistency was assessed by Cronbach's alpha and Omega index. Results: A total of 221 mental health nurses participated in the study (response rate = 62.08%). The scale's final structure has 25 items. Cronbach's alpha was 0.93, ranging from 0.78 to 0.88 for each of the factors. The cumulative variance explained in a four-factor structure was 71.12%. Discussion: The Therapeutic Relationship Assessment Scale (TRAS)-Nurse presents good psychometric properties. In the light of Benner's theory, it can be an useful tool for novice nurses to better understand what aspects they should pay attention to for establishing a successful TR. Implications for Practice: Mental health nurses can use the TRAS-Nurse, thus having a scale available that allows them to self-assess the quality of TR they establish with their patients.
