Semi-structured telephone interviews (N = 647)
| |
Interviewer:
|
For both sources of data:
|
| |
• How each core element is being implemented
|
• Trained to take extensive notes, including key verbatim phrases to record content of each interview
|
• Investigators regularly reviewed interviewer’s and TA providers’ interview summaries and field notes
|
| |
• Adaptations made to the core elements
|
• Cleaned each summary note, making sure team had data on each relevant topic in interview guide
|
• Bi-weekly meetings addressed TA and field notes
|
| |
• Rationale for adaptation
|
• Indicated verbatim phrases
|
• Discussions focused on barriers and facilitators to effective implementation, as well as how to address them in TA
|
| |
• Problems encountered in implementation
|
• Ensured accurate record of interview content and interview conditions (i.e., level of rapport, apparent distractions, general level of flow for each interview)
|
• Field notes, summaries, and analytical codes applied to relevant sections of each summary note were entered into qualitative database
|
| |
• Approaches used to overcome challenges
| | |
|
Extensive field notes and commentary
| |
TA providers:
| |
| |
• Barriers and facilitators to implementation fidelity
|
• Had been coordinators in prior efficacy trials, and were extensively trained and supervised in previous research
| |
| |
• Problems encountered in implementation
|
• Thus had clear understanding of fidelity to original implementation methods
| |
| |
• Approaches used to overcome challenges
|
• Jotted extensive notes during all TA sessions (delivered by telephone and/or e-mail)
| |
| | |
• Subsequently created detailed commentary about each TA session, operationalized as fieldnotes
| |
| | |
• Were trained on the study domains (barriers and facilitators to intervention fidelity) to ensure recording of relevant data when topics of interest arose during TA
| |
| | |
• Used template for TA fieldnotes, which contained headings for each relevant study topic where notes were taken
