TABLE 1
Themes and subthemes in the literature
[i] Comments: Table 1 provides an overview of the themes and subthemes identified in the literature and the studies which formed these themes. A study can appear more than once if it addresses more than one theme.

[i] Comments: N reflects the number of times a data collection method is used in the studies addressing each theme. The total number may exceed 49 because some studies cover multiple themes by using multiple data collection methods. For a comprehensive overview of how the articles were coded, see Supplement 1. See Appendix 1 for source information.
