Validity and Reliability Study of the Turkish Version of the Transactional Analysis Scale: A Sample of Nurse Managers.

This study aimed to adapt the Transactional Style Inventory for Managers (TSI-M) into Turkish and evaluate its psychometric properties among nurse managers. Effective communication is a core competency for nurse managers, influencing both staff satisfaction and the quality of healthcare delivery. Since communication behaviors are shaped by ego states, reflecting internalized thoughts, feelings, and experiences, a valid and reliable tool is essential to assess these states in managerial contexts. The TSI-M was translated into Turkish using a standardized back-translation procedure and reviewed by a panel of experts. The sample consisted of 230 nurse managers (77% female) working in various healthcare institutions. Validity and reliability were assessed using item analysis, the content validity index (CVI), and confirmatory factor analysis (CFA). CFA supported the construct validity of the scale, yielding acceptable model fit indices ( /df = 3.11; GFI = 0.90; AGFI = 0.90; CFI = 0.94; RMSEA = 0.06; RMR = 0.06). Internal consistency was high for the total scale (Cronbach's  = 0.93) and good to be acceptable across subscales: parent ( = 0.895), adult ( = 0.812), and child ( = 0.836). While the parent and child ego state subscales demonstrated strong convergent and discriminant validity, the adult ego subscale showed slightly below-threshold composite reliability (CR = 0.692) and weaker discriminant validity. The Turkish version of the TSI-M is a valid and reliable instrument for assessing ego states in nurse managers and holds practical value for leadership development and communication training in healthcare management.
