Table 1 The Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework

Reach

• Participant’s and decliner’s characteristics (e.g., compare sociodemographic information between participant and nonparticipant OFWs; reasons for not participating; the most effective recruitment strategy)

• Administrative data

• Open-ended questions in a questionnaire

Effectiveness

• Primary outcome (depression severity)

• Secondary outcome (anxiety and wellbeing)

• Reason for withdrawing

• Questionnaires

• Interviews and focus groups

Adoption

• Ineligibility reasons

• Barriers and enablers of SbS-F adoption into community partner’s program and recommendations for addressing barriers and maximizing adoption

• Community partner’s knowledge and beliefs about the SbS-F program

• Administrative data

• Questionnaires

• Interviews and focus groups

Implementation

• Participants’ adherence to the intervention (e.g., duration in accessing the SbS-F and reasons for missing sessions)

• Participants’ perceived benefit from the intervention

• Barriers and enablers in implementing the program and modifications needed to maximize the implementation (from participants’ and staff’s perspective)

• Relevance of the SbS-F story and techniques in participant’s lives

• Time and resources required for supporting the program (e.g., number of e-helpers needed and their total working time; e-helpers’ training, selection, and retention)

• Administrative data

• Questionnaires

• Interviews and focus groups

Maintenance

• Attrition rates

• The durability of intervention effects on depression

• Resources, strategy, and policy needed to integrate and maximize the SbS-F intervention into community partner’s program after the study ended

• Administrative data

• Questionnaires

• Interviews and focus groups
