Formative stage
The objective of this stage is to evoke feedback from the key intervention stakeholders to guide on designing and developing the newly proposed DAT. We will first survey 142 participants from each group to investigate enablers and barriers to using DAT. This figure is based on selecting an arbitrary percentage of 50% experiencing barriers for using DAT with Next, we will purposively select 20 participants from each group, considered enough to reach ‘saturation’ of information, to use the DAT for 1 month. After signing informed consent, we will provide mothers, parents/caregivers of children and adolescents with a Wisepill® box which they will use for a month. After a month, we will interview each of them, including the children whose status has been disclosed on their experience with the box and the need for SMS content to be developed for the customized digital tool. We will also hold two focus group discussions with each group of breastfeeding mothers, parents/caregivers and adolescents. The outcomes of the formative research will be as follows:
An overview of needs for SMS contents and timing for reminder cues to take medicationAn overview of needs for SMS contents and timing for reminder cues for clinic visitsAn overview of further needs for other SMSs, such as educational and informational texts, including timing and frequencyAn overview of enablers and barriers to the success of the interventionQuantitative data from the survey will be analysed descriptively using frequency tables, chi-square tests and
