Common themes were identified and the interrelationship of theme clusters was explored.
The unit of analysis here is thus the theme clusters.
While the Adjusted Rand Index provides a global measure of similarity between partitions, the individual abstract clusters derived from NCuts partitioning can also be compared pairwise with the SFN theme clusters.
No single study contained all the sub-themes, although all studies contributed to all three theme clusters.
Features identified were grouped into themes, and then into theme clusters with common traits, and finally into more general categories.
Three theme clusters were found: the distinctness of the volunteer role, the characteristics of the role, and the volunteer experience of the role.
Further details can be seen in Additional files 3 and 4. The findings are grouped around three theme clusters: the distinctness of the volunteer role, the characteristics of the role, and the volunteer experience of the role (see Table 3).
To ensure the trustworthiness of the data, first, the theme clusters were re-validated by the researcher by going back to the original transcript using the original statements made by the interviewees.
The ranked scores within each consultation group have a possible range from 1 (for the research theme receiving the least votes) to 6 (for the research theme receiving the most votes. Six was the maximum number of research theme clusters identified during the vote casting exercise in any consultation group).
The weekdays will be regimented: Tuesdays, factual entertainment; Wednesdays, documentaries; Thursdays, drama and comedy under "Playhouse Presents" in themed clusters of four.
