Methods: In this study, translation, back translation, and cultural adaptation processes were completed. One hundred twenty-two intern or graduated physiotherapists participated. Results: The neurological and cardiopulmonary scales demonstrate a high level of reliability (Cronbach's ? = 0.81, 0.87 respectively). The orthopedic subscale is also found to be reliable (Cronbach's ? = 0.76). The Turkish version of the PSE questionnaire exhibits excellent internal consistency for neurological, orthopedic, and cardiopulmonary subscales (with Cronbach's ? values of 0.98, 0.98, and 0.99 respectively). Conclusion: Turkish PSE Questionnaire is both a valid and reliable scale. It can be used to assess the professional self-efficacy levels of both intern and graduated physiotherapists. © Content of this journal is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License https://creativecommons.org/licenses/by-nc-nd/4.0/.eninfo:eu-repo/semantics/openAccessEducationSelf-EfficacyValidityTurkish Version of Physiotherapist Self-Efficacy Questionnaire: Cultural Adaptation, Validity, and ReliabilityArticle2-s2.0-10503238987210.5152/ArcHealthSciRes.2026.25116Q413
