ADAPT-ITT model [55] adaptation process

Adaptation phase	Task	Methods
1. Assessment	Who is the new target pop. and why is it at risk?	Reviewed literature on alcohol use and other mental health needs among PWH
		Conducted qualitative interviews on acceptability of ACT among PWH
2. Decision	What EBI is to be adapted?	Reviewed literature and identified brief, telephone-delivered ACT for smoking cessation as intervention to adapt
3. Administration	What in the original EBI needs to be adapted and how?	Identify what elements of intervention need to be adapted by examining the ACT for smoking cessation manual
4. Production	How to produce and document adaptation to EBI?	Consult study team to solicit feedback on first round for changes and document agreed upon changes
		Generate final draft of adapted intervention manual, maintaining fidelity to core elements and underlying theory of original EBI
5. Topic experts	Who can help adapt the EBI?	Conduct qualitative interviews & focus group discussions with PWH who are hazardous drinkers, and HIV care providers, to gather input on draft of adapted intervention manual
6. Integration	What is going to be included in the adapted EBI to pilot?	Analyze qualitative data
		Integrate feedback and modify intervention manual content
		Generate final adapted intervention manual
7. Training	Who needs to be trained and how?	Establish procedures for/conduct ACT interventionist trainings
		Finalize procedures for (1) supervision format, frequency, & intensity, (2) fidelity monitoring and analysis, (3) trainings for all laboratory-based tasks
8. Testing	Did adaptation work?	Conduct pilot feasibility and acceptability RCT
