Participant questionnaires
All 1113 RCT participants (560 allocated to intervention and 554 to comparison group) were asked to complete self-report questionnaires at baseline, when the intervention group had finished the program, (post-program) and 12 months after it began (12-months). The intervention group participants were also asked to complete additional self-report questions about their experiences of the program both post-program and at 12-months. The pre-program questionnaire asked about motivations for joining EuroFIT. Post-program questionnaires asked which components and tools of the EuroFIT program men received, used or did not use, and which they found useful. The 12-month questionnaire was designed to assess participants’ views on the ongoing usefulness of the components and tools in EuroFIT.
