Diagrammatic plan of analysis: a Focus group discussions were recorded and photos taken of the playful design elements. b All text and visual data were coded by two investigators in an iterative process, steadily comparing emerging codes until consensus of a final code book was reached. Codes were then sorted into themes. During this process, two multidisciplinary meetings were held for in-depth discussion of the data, refining the code list, and reaching consensus on central themes. c The two investigators compared the findings from all focus groups to identify recurrent patterns. During two multidisciplinary meetings the team members deepened the comparative analyses and developed a thematic map of the central topics and the relationships between central themes. d The integrated findings were vetted with the representatives of the focus groups participants
