Table 4 Observations and qualitative data for the feasibility inquiry

Acceptability

To what extent is a new idea, program, process or measure judged as suitable, satisfying, or attractive to program deliverers? To program recipients?

“The picture is good and enables us to easily understand.” “We are very happy to learn many things, no one feels bad. Everybody is happy.”

Demand

To what extent is a new idea, program, process, or measure likely to be used (i.e., how much demand is likely to exist?)

“This type of education should be given to all Tanzanian people, pregnant women and their families.”

Implementation

To what extent can a new idea, program, process, or measure be successfully delivered to intended participants in some defined, but not fully controlled, context?

It takes more time to complete the self-administered questionnaire than what was planned by the researchers.

Practicality

To what extent can an idea, program, process, or measure be carried out with intended participants using existing means, resources, and circumstances and without outside intervention?

The collaborator can conduct the intervention, but more local nurses or community health workers need to be educated to implement the intervention and expand the research.

Limited efficacy

Does the new idea, program, process, or measure show promise of being successful with the intended population, even in a highly controlled setting?

The scores of the measure showed some significant differences before and after the intervention with the limited convenient sample. More changes are expected.
