To ensure completion of the data, preliminary findings and recommendations were presented back to participants in the form of a workshop. The 4 h workshop, facilitated by project leaders was a means to achieve consensus and to validate the findings generated by participants. The workshop approach contributed to the trustworthiness of the project where Denzin and Lincoln (2005) and Wertz (2011) have advocated, validity should be judged by fit, relevance, workability, trustworthiness, and modifiability with the aim of establishing credibility, dependability, confirmability, transferability, and authenticity (Polit and Beck, 2012).
