Developing a Questionnaire Regarding the Perceptions and Practices of Filipino Physical Therapists in the Management of Patellofemoral Pain Syndrome in the National Capital Region

Aim: To develop a questionnaire to know the perceptions and practices of Filipino physical therapists in the management of PFPS. Methods: This study consists of 2 phases. Phase 1 involves questionnaire development regarding the perceptions and practices of Physical Therapists in the management of Patellofemoral Pain Syndrome, using the domains of the socio-ecological model. Review of existing literature and personal input from the researchers was used in developing the questionnaire. Phase 2 consists of content validation of the developed questionnaire using the Modified Delphi Technique with five expert panelists to validate each item and the questionnaire as a whole. A total of three rounds of validation were performed before a consensus was reached. Results: After a thorough literature search, a questionnaire was developed which was entitled “Perceptions of Physical Therapists towards Patellofemoral Pain Questionnaire (PPTPFPQ)”. Content validity of the PPTPFPQ was established after three rounds of validation in which the PPTPFPQ showed a high individual and scale content validity index (I-CVI range: 0.8 to 1.0; S-CVI = 0.94). The final instrument is a 26-item questionnaire that consists of 3 domains and 26 categorical questions. The 3 domains are 1) Individual domain 2) Organizational domain 3) Public Policy Domain Conclusion and Implications: The PPTPFPQ acquired an acceptable measurement of content validity and can be used in future studies to assess the perceptions and practices of PTs with regards to their management of patients with PFPS.
