Ethics approval and consent to participate

At the beginning of each questionnaire the statement was included that filling in the questionnaire was taken as consent to participate in the study. This form of consent to participate in the study was obtained to protect respondents’ anonymity avoiding additional documents requiring their signature. The research protocol together with the indicated form of respondents’ consent to participate in the study were approved by the Ethical Commission at the University of Rzeszów (Resolution No 6/9/2017).
