Trustworthiness of emerging themes was ensured through established means of demonstrating referential rigor, including adequacy, negative case analysis, and peer debriefing [ 21].
In addition, the team met regularly during the data collection period to talk about the developing analysis and to debrief more generally about data collection activities.
However, LS maintained a field diary and engaged in reflexive processes during data collection and analysis; debriefing with local (PK) and institutional (ST and ER) supervisors were done to mitigate the possible bias.
RA, LA and MC wrote the face to face cognitive debriefing interview guide, RA performed the cognitive debriefing analysis and all authors reviewed and commented on the results of the face to face cognitive debriefing.
The sample DCFs illustrate the two steps in the collection and analysis of cognitive debriefing data, as follows: 1. Interviewers complete and submit a DCF for each subject as specified in the Cognitive Debriefing Manual.
To demonstrate rigour in our research we will draw upon the following 'validation strategies' for qualitative research: [ 27] 1) prolonged engagement in the field; 2) peer review and debriefing; 3) negative case analysis; 4) clarifying researcher bias; 5) member checking; and 6) rich, thick description which enables readers to make decisions about transferability.
Systematic analysis began with a reading of transcripts and debriefing notes, followed by manual coding of the narratives.
Meetings were recorded and transcribed for analysis, which consisted of coding, peer debriefing, thematic analysis, and interpretation.
Current approaches suggest the employment of quantitative (e.g. factor analysis) and qualitative (e.g. patient debriefing questionnaires and patient panels) techniques.
Information from the debriefing interview, factor analysis and item response theory analysis resulted in the removal of one item QLQ-ELD15→QLQ-ELD14 QLQ-ELD15→QLQ-ELD14 QLQ-ELD15→QLQ-ELD14ructure to five scands (mobility, worevisionofthethers, future worries, maintaining proposedand illnescalerden) and two structureems (jointostifivescales famobilityport).
