Triangulation provided a validation process, thereby increasing the construct validity and trustworthiness of our findings.
29 30 The concepts of validity and trustworthiness within qualitative research are understood in terms of the credibility of the analytical process.
The acceptability of the methodology will add to the validity and trustworthiness of the findings.
As with any empirical study, there may be threats to the validity and trustworthiness of our work (Kitchenham and Pfleeger 2002b).
An important aspect of construct validity is the trustworthiness of score meaning and interpretation [ 40].
Rigour influences the quality of trustworthiness.
That clinical and interpretive research also follows indicators of trustworthiness (the equivalent of validity and reliability in the context of experimental research design) that are different from those used in experimental research has not become part of the evidentiary conversation.
The study used a triangulated research design, where multiple data collection methods are combined to examine the same phenomena from different perspectives, strengthening the trustworthiness and validity of the evidence [ 28, 29].
A number of validity criteria for trustworthiness need to be highlighted and discussed [ 71].
The Delphi consensus technique has been used widely in health care research [ 9, 10] and its validity and trustworthiness have been the topic of many debates.
We followed Lincoln and Guba's principles of trustworthiness [ 41] as well as Yin's validity guidelines for case methods [ 38].
