Fifteen articles that met the selection criteria were reviewed. Thirteen were qualitative and two were mixed method studies. Critical appraisal of the qualitative studies was conducted using a selection of questions from the Critical Appraisal Skills Programme (CASP 2006). Critical appraisal of the mixed studies was conducted using a selection of questions from the University of Salford (2001) evaluation tool for mixed studies.
Following Roberts and Taylor (2002) the qualitative studies in this review were further evaluated using categories of credibility, fittingness, auditability and confirmability to determine rigour or ‘validity and reliability’.
Scholarly cholarly PAPER
Thematic analysis was used to identity themes or patterns within the texts. These themes were then refined by grouping them into specific categories or sub‑themes representing their own unique connection within the research aim (Braun and Clarke 2006; Roberts and Taylor 2002). Two themes were identified and five sub‑themes. Some articles represented more than one theme (see table 1).
