Patient-reported experience measures are self-reporting instruments that measure the patients’ experience during provided health care. The PEPAP – Q questionnaire is a specific experience measure developed for use in outpatient physiotherapy. The aim of this work was to localize the PEPAP-Q questionnaire into the Croatian language and use it to evaluate the experience of outpatient physiotherapy for patients with diseases of the musculoskeletal system and connective tissue in the Health Center Zagreb - Center. The localization of the Questionnaire into the Croatian language was carried out using the method of double-blind translation from English to Croatian, and a focus group was used for intelligibility review in Croatian language. A sample of 150 respondents was collected in five therapeutic groups during the two-month period of the research using the PEPAP-Q questionnaire. The respondents rated the experience worst in the domains regarding the information provided by physiotherapists and regarding too many patients compared to the number of therapy devices and therapy tables. This is first research measuring patients’ experience in outpatient physiotherapy and forms a useful basis for testing psychometric properties, further validation, and potential application of the Questionnaire in outpatient physiotherapy in Croatia.
