Flowchart of the mixed-methods sequential explanatory design

Phase	Procedure	Product
Phase 1: data collection	• Web-based survey	• Numerical data • Freetext responses
Phase 1: data analysis	• Multi-level models • Sensitivity analysis • Coding free text responses	• Descriptive statistics • Coded themes
Connecting Phase 1 and 2	• Purposive sampling frame determined by survey findings on specific domains • Develop interview questions to answer questions raised by survey findings	• Interview sample • Semi-structured interview schedule
Phase 2: data collection	• Individual semi-structured phone interviews (n = 20) • Verbatim transcription of interview audio recordings	• Interview transcripts
Phase 2: data analysis	• Framework analysis	• Thematic framework • Indexed and charted data • Mapping and interpretation of the data
Integration of Phase 1 and 2 results	• Interpretation of the survey data • Refinement to implementation process	• Discussion • Refinement of the Mini-AFTER intervention • Revision of Mini-AFTER study design • Feasible process for implementing Mini-AFTER in BCN practice • Future research
