Insights
This study developed "Milk Man," the first breastfeeding app for fathers, to improve infant feeding support. The app, designed with user input and behavior theory, received high ratings and is now in clinical trials.
Area of Science:
- Public Health
- Mobile Health (mHealth)
- Health Behavior Theory
Background:
- Low rates of exclusive breastfeeding in Australia highlight a need for improved support.
- Father's involvement is crucial for breastfeeding success, yet interventions often overlook this demographic.
- Mobile technology presents an innovative platform for enhancing health literacy and promoting healthy behaviors.
Purpose of the Study:
- To develop the first evidence-based breastfeeding mobile application specifically designed for men.
- To leverage formative research, behavior change theory, and user feedback to create an app that enhances men's ability to support breastfeeding partners.
- To provide accessible information and social support to fathers through a dedicated mobile platform.
Main Methods:
- Utilized Social Cognitive Theory to guide the app's design and development process.
- Conducted formative research, including focus groups with fathers (n=18) and health professionals (n=16), to inform app features.
- Employed a think-aloud study with fathers (n=4) and the Mobile Application Rating Scale (MARS) to test and refine a prototype.
Main Results:
- Focus groups provided valuable insights from fathers and health professionals, directly influencing app development.
- Usability testing identified key areas for improvement, such as adding a tutorial and enhancing personalization.
- The app prototype achieved a high average MARS score of 4.3 out of 5, indicating positive user reception.
Conclusions:
- "Milk Man" is identified as the first breastfeeding support application specifically targeting men.
- The app's development followed a rigorous, best-practice approach, integrating multidisciplinary input and behavior change principles.
- Initial testing demonstrated positive user engagement and usability, with the app currently undergoing further evaluation in a clinical trial.
Background:
Despite evidence of the benefits of breastfeeding, <15% of Australian babies are exclusively breastfed to the recommended 6 months. The support of the father is one of the most important factors in breastfeeding success, and targeting breastfeeding interventions to the father has been a successful strategy in previous research. Mobile technology offers unique opportunities to engage and reach populations to enhance health literacy and healthy behavior.
Objective:
The objective of our study was to use previous research, formative evaluation, and behavior change theory to develop the first evidence-based breastfeeding app targeted at men. We designed the app to provide men with social support and information aiming to increase the support men can offer their breastfeeding partners.
Methods:
We used social cognitive theory to design and develop the Milk Man app through stages of formative research, testing, and iteration. We held focus groups with new and expectant fathers (n=18), as well as health professionals (n=16), and used qualitative data to inform the design and development of the app. We tested a prototype with fathers (n=4) via a think-aloud study and the completion of the Mobile Application Rating Scale (MARS).
Results:
Fathers and health professionals provided input through the focus groups that informed the app development. The think-aloud walkthroughs identified 6 areas of functionality and usability to be addressed, including the addition of a tutorial, increased size of text and icons, and greater personalization. Testers rated the app highly, and the average MARS score for the app was 4.3 out of 5.
Conclusions:
To our knowledge, Milk Man is the first breastfeeding app targeted specifically at men. The development of Milk Man followed a best practice approach, including the involvement of a multidisciplinary team and grounding in behavior change theory. It tested well with end users during development. Milk Man is currently being trialed as part of the Parent Infant Feeding Initiative (ACTRN12614000605695).
