Declarations
:
: Ethical approval is not required for PPI representatives acting as research partners. P-STEP users were not acting as research subjects but as advisers contributing their knowledge and expertise by experience to the design of P-STEP.
: Consent was granted for the photos, which are presented in the additional files. As this manuscript describes the development process of the P-STEP project and does not present participant data, consent was not obtained for the PPI activities. For this reason, as we are presenting the development process based on PPI activities, we also believe it would not be appropriate to outline the characteristics of the users.
: The authors declare no competing interests.
