In recent years, mobile technology has opened up new possibilities for healthcare, with one of the most intriguing advancements being “passive sensing technology.” This powerful tool is already transforming physical health, and now it’s showing promise in mental health care too. The StandStrong project, led by researchers in Nepal, is one such initiative utilizing passive sensing to support mothers struggling with depression. By exploring how passive sensing works, how it’s applied in StandStrong, and the benefits and challenges involved, we can get a closer look at how innovative technology is helping to improve mental health care in low-resource settings.

What is Passive Sensing Technology?

Simply put, passive sensing technology collects data without requiring active effort from the user. This means that everyday devices, like smartphones, can gather information on people’s physical movements, location, sounds, and even sleep patterns. Equipped with various sensors, these devices record data such as physical activity through accelerometers, movement patterns via GPS, and social interactions by detecting the presence of speech through audio sensors. Importantly, passive sensing data collection happens in the background, which is why it’s called “passive.” This non-invasive data-gathering method is helpful for mental health, as it can reveal behavioral patterns and emotional well-being without the need for individuals to remember to record every detail themselves.

The StandStrong Project: Supporting Mothers with Depression

The StandStrong project is an innovative mental health program that uses passive sensing technology to support mothers experiencing depression. Created by a team of international researchers, StandStrong focuses on young mothers in Nepal, a region where mental health resources are often limited. This project is unique because it uses passive sensing data to enhance the work of lay counselors—individuals without extensive mental health training—who provide basic mental health support to these mothers.

Through the StandStrong mobile application, lay counselors can access data from the mother’s smartphone, which monitors key indicators such as physical activity, GPS location, proximity to her child, and social interactions. For example:

GPS data creates a “heat map” showing where the mother spends her time, helping counselors understand her activity patterns.
Proximity data indicates the time spent close to her baby, a useful measure of mother-child bonding.
Activity tracking reveals levels of movement, indicating when the mother may be more active or less active, which can correlate with mood.
Audio sensing detects the presence of human speech, giving insights into the mother’s level of social interaction.

Using this data, counselors can help the mothers set goals to spend more time with their babies, become more physically active, or engage in social activities. This is a significant advantage because these mothers don’t have to remember to self-report their activities—something especially helpful for individuals with depression, who may struggle to track or report daily patterns.

Potential Benefits of Passive Sensing in Mental Healthcare

The StandStrong project highlights several promising benefits of using passive sensing in mental health care:

Objective Data: Unlike self-reported information, passive sensing data is objective and collected consistently. This allows counselors to track real changes in behavior over time.
Increased Access: Passive sensing can support mental health interventions in low-resource areas by enabling non-specialists to provide meaningful support with data-driven insights.
Continuous Monitoring: The technology enables continuous monitoring outside clinical settings, offering a more comprehensive view of mental health.
Support Between Sessions: For those with limited access to mental health services, passive sensing provides a way to stay connected and receive support outside regular appointments.

For mothers dealing with depression, these benefits can be life-changing. They can receive support tailored to their needs and find encouragement to reach their goals.

Challenges to Ethical and Effective Use of Passive Sensing

While promising, there are several challenges that StandStrong and similar projects must overcome for passive sensing to be both successful and ethical.

Privacy Concerns: Continuous data collection raises important privacy questions. Participants must feel confident that their information is secure and used responsibly. In StandStrong, both the mothers and their family members were given detailed explanations about the data collected, and consent was sought not only from the mothers but also from family members to respect cultural sensitivities.
Battery and Data Usage: Constantly gathering data, especially audio and GPS data, can drain a phone’s battery and may require cellular data access. For low-resource settings, finding ways to reduce battery strain and data needs is essential.
Data Interpretation: Passive data alone can only reveal part of the picture. Counselors need training to interpret this data effectively, which StandStrong provides through additional counselor training sessions on using the app. Nonetheless, further research is needed to ensure that data interpretations are accurate and helpful.
Scalability and Accessibility: While smartphones are common, they are not universally accessible, and the cost can be a barrier. Additionally, non-specialist counselors need both technology and cultural training to integrate the app into their sessions effectively. StandStrong addresses this by using affordable devices and simplifying the app for ease of use.
Ethical Use and Psychological Impact: Beyond technical challenges, ethical use is paramount. Participants must feel that the monitoring enhances their care without feeling invasive or triggering additional stress. The StandStrong project navigates this by fostering open communication with participants and ensuring that passive sensing is viewed as a supportive tool rather than a surveillance method.

Looking Forward: The Future of Passive Sensing in Mental Health

The StandStrong project is pioneering a new model of mental health care that leverages technology to enhance support for individuals in low-resource settings. As passive sensing technology continues to advance, projects like StandStrong will help refine best practices for its ethical use, training, and application in mental health care. By addressing challenges like privacy, accessibility, and data interpretation, passive sensing can potentially reshape the future of mental health services, making them more accessible and tailored to individual needs around the world.

The StandStrong project demonstrates that with careful implementation, passive sensing can be a powerful ally in supporting mental health and promoting well-being, especially for those who need it most.
