Table 3 Use of the model COM-B to identify the components of the intervention
Components COM-B | What needs to happen for the target behaviour to occur? | Is there a need for change? | |
|---|---|---|---|
CAPABILITY (C) | Physical capability | Have the physical capacity to read the PtDA. | No. The reading of the PtDA doesn’t require special physical skills. |
Psychological capability | Know how to use the PtDA. | Yes. In another study, more than half of the participants did not did not know of any PtDAs, therefore did not know how they are used. | |
OPPORTUNITY (O) | Physical opportunity | The PtDA is available. | Yes. For the tool to be used, it must be available. |
Social opportunity | Have the opportunity to see other women use the PtDA. | Yes. As the PtDA is not available yet, pregnant women have not heard about it or had the opportunity to see anyone else using it. | |
MOTIVATION (M) | Reflective motivation | Believes that using the PtDA could be useful. | Yes. In another study, more than half of the participants did not know of any PtDAs, therefore did not know it could be useful. |
Automatic motivation | Have established a routine and a habit to use the PtDA. | No. It is a one-time behaviour so there is no need for it to become habitual. | |
Diagnosis of COM-B components | Psychological capability, physical opportunity, social opportunity and reflective motivation are components needed in an intervention to increase women’s intention to use the PtDA. | ||
