Objective: This study aimed a) to investigate knowledge, attitudes, and self-reported use of shared decision-making (SDM) among physiotherapists in Germany, b) to explore their association with demographic characteristics, and c) to assess barriers to the implementation of SDM. Methods: We assessed above mentioned domains using an online survey. Two-level logistic regression models were used to examine factors associated with knowledge, attitudes and self-reported use of SDM. Results: 60.5% of a total sample of 357 participants reported to have had no knowledge on SDM before participating in the survey. Attitudes towards SDM were mostly positive, half of all participants expressed a preference for SDM. About two thirds of all participants reported to use a rather paternalistic approach in routine care. Knowledge, attitudes, and self-reported use of SDM were associated with several demographic characteristics. Conclusion: SDM was perceived as an appropriate concept in physiotherapy. However, missing knowledge and limited self-reported use of SDM in routine care on the one hand and positive attitudes towards SDM on the other hand indicate a need for action. Practice implications: In order to emphasize the use of SDM in physiotherapy efforts need to be undertaken in research, clinical practice and health policy.
