Psychosocial Agency and Collective Belonging: A Mixed-Methods Evaluation of a Multi-Level Intervention with Underserved Young Adults

In the years following the global pandemic, the mental health of young adults has reached a critical point, with many struggling more than previous generations. For decades, the standard approach to helping people feel better has focused on the individual: teaching a person how to manage their own stress, how to calm their own racing thoughts, or how to regulate their own emotions. While these skills are valuable, a growing number of researchers believe this approach misses a crucial piece of the puzzle. Human beings are not isolated islands; our sense of well-being is deeply rooted in our connections to others and our sense of belonging to a community. When people feel cut off from their neighbors or powerless to change their circumstances, their mental health often suffers. The question facing scientists today is whether we can design programs that do more than just teach a person to cope alone, but instead help them build a sense of shared strength and collective purpose.

This is the central question explored in a new study conducted in South Boston, Massachusetts, by researchers from Harvard University and the University of Cambridge. The team worked with a group of underserved young adults—many of whom faced daily challenges such as housing instability, involvement with the justice system, or substance use—to test a program that combined personal mindfulness practices with a method called Participatory Action Research. This research method is distinct because it does not just ask people to answer questions; it invites them to become researchers of their own lives, identifying problems in their community and working together to find solutions. The goal was to see if blending personal emotional skills with the power of collective action could improve both individual mental health and the group's sense of connection.

The program unfolded over five months, beginning with sessions designed to build trust and inner stability. Participants practiced mindfulness, gratitude, and active listening, learning to recognize their own emotions without judgment. As the weeks passed, the focus shifted. The group began to examine the larger forces affecting their lives, such as power dynamics and social identity. Eventually, they moved into a phase where they identified specific community issues they wanted to address. Two major concerns emerged: employment and housing. The group then worked to analyze data on these topics and proposed concrete steps to improve the situation, such as finding better ways to secure housing vouchers and standardizing applications for government assistance. The journey concluded with the young adults presenting their findings and proposals to leaders at the organization and at Harvard University.

To understand if this approach worked, the researchers used a mixed-methods design, gathering two different types of evidence. First, they asked participants to fill out standard surveys before and after the program. These surveys measured general mental well-being and the ability to manage difficult emotions. Second, after nearly every session, the young adults wrote short diary entries. These entries included ratings of how much they enjoyed the session and how close they felt to the other participants, along with open-ended reflections on what the experience meant to them. This dual approach allowed the team to see not just if people felt better, but how their experience of the group changed over time.

The results showed a clear pattern of improvement. On the standard surveys, the group's overall sense of well-being increased, and their ability to regulate their emotions showed parallel gains. Specifically, the young adults reported having more energy, feeling more cheerful, and finding it easier to stay focused even when they were upset. These changes were not just statistical averages; the data suggested a consistent upward shift across the group. At the same time, the diary entries told a story of deepening connection. As the months went by, participants rated their enjoyment of the sessions higher and reported feeling closer to one another. The sense of belonging within the group grew steadily, moving from a collection of individuals to a cohesive unit.

Perhaps the most revealing findings came from analyzing the words the participants used to describe their experiences. In the early weeks, their language was introspective and focused on the self. They spoke of "opening up," "learning about myself," and finding "peace." These were signs of individuals trying to stabilize their own internal worlds. However, as the program progressed, the vocabulary shifted dramatically. The words "community," "heard," and "seen" began to appear with increasing frequency. The focus moved from solitary reflection to mutual recognition. Participants began to describe the group as a source of shared enthusiasm and collective identity. One person noted that they liked discussing real-life issues and finding solutions they could all use. The language evolved from a quiet, internal calm to a vibrant, shared energy.

The researchers suggest that this developmental arc—from self-regulation to collective agency—is the key mechanism of the program's success. By first building a foundation of personal safety and emotional skill, the participants were able to engage more fully with one another. Once that trust was established, the group could tackle the harder work of addressing systemic issues together. The study indicates that when people feel accepted and connected, they are better equipped to reclaim a sense of power over their lives. While the study was exploratory and involved a small number of participants, the convergence of survey data, diary ratings, and language analysis points to a promising path forward. It suggests that interventions which weave together personal growth, relational support, and civic engagement may offer a more complete way to foster well-being than focusing on the individual alone.

The authors are careful to note that this was a preliminary investigation. The sample size was modest, and without a separate control group to compare against, it is difficult to say with absolute certainty that the program caused all the changes observed. Other factors, such as the general support provided by the organization, could have played a role. However, the consistency of the findings across different types of data provides a coherent picture. The study does not claim to have solved the complex mental health crisis facing young adults, but it offers a compelling example of how relational practices can help individuals move from isolation toward shared engagement. By creating spaces where people feel both safe and connected, such programs may lay the groundwork for both psychological healing and the kind of community action that can lead to lasting social change.
