Although Social Exchange Theory was first developed several decades ago, researchers still use it today to understand how people communicate and maintain relationships. As communication environments have changed, especially with the growth of technology and online interaction, scholars have continued applying the theory to new areas of research. Even in modern settings, people still tend to think about relationships in terms of rewards, costs, and whether the interaction feels fair, which reflects the core principles of exchange processes discussed in earlier research (Lawler, 2001).
One area where Social Exchange Theory has expanded is digital communication and online communities. A large amount of interaction now happens through social media platforms, online forums, and other digital spaces. Even though these interactions are not face-to-face, people still evaluate whether participating in these spaces is worth their time and effort. For example, users may look for rewards such as support from others, recognition, useful information, or simply a sense of belonging. You can see this clearly on platforms like Instagram or TikTok, where people often share posts or comments expecting likes, replies, or some type of interaction in return. Chen and Li (2017) found that trust and reciprocal communication play an important role in whether individuals stay active in online communities. When people feel that others respond to them, support them, or contribute back to the conversation, they are more likely to remain involved. In this way, the idea of reciprocity still applies even when communication happens through technology rather than in person, which is also supported by broader relational exchange frameworks (Lawler & Thye, 1999).
Social Exchange Theory has also been widely applied to modern workplaces. Researchers often use the theory to better understand relationships between employees, supervisors, and organizations. In many workplaces, employees evaluate whether the effort they put into their job is matched by recognition, support, or opportunities in return. Cropanzano, Anthony, Daniels, and Hall (2017) explain that feelings of fairness in organizations are often shaped through these types of exchange relationships. When employees feel that their contributions are valued, trust in leadership tends to grow. Because of that, they are also more likely to remain committed to the organization. However, when workers believe their effort is not recognized or rewarded, frustration and disengagement can occur. These types of situations help explain why Social Exchange Theory is often used to study employee satisfaction, burnout, and turnover within organizations, especially in relation to perceived organizational support and obligations (Shore & Tetrick, 2009).
Another area where the theory has been applied is health communication. Communication between patients and healthcare providers can also involve exchange processes that influence trust and cooperation. Patients often evaluate their experiences based on whether they feel heard, respected, and clearly informed. When doctors provide clear explanations, empathy, and support, these interactions can function as relational rewards that strengthen the relationship. On the other hand, poor communication may lead to frustration or a lack of confidence in the provider. Researchers have found that these exchange dynamics can influence whether patients follow medical advice and continue working with the same healthcare professional.
Researchers have also begun combining Social Exchange Theory with other theoretical perspectives to better understand the emotional side of relationships. Early versions of the theory mainly focused on logical cost and benefit calculations. More recent research recognizes that emotions, trust, and feelings of belonging also influence how people evaluate interactions. Molm, Schaefer, and Collett (2007) explain that trust and commitment often develop when individuals take risks in relationships and receive positive responses in return. When people feel emotionally supported or valued, those rewards can strengthen relationships over time. This shift is seen in recent studies that combine social exchange theory with Social Identity theory, showing that the dynamics in social exchanges can not be confined to fit everyone. Specifically, researchers have found that while social support can create a strong organizational identity, this can lead to their commitment to keep them in unsupportive environments (Simbula et al.,2023).
Taken together, these examples show that Social Exchange Theory continues to be relevant in modern communication research. Whether people are interacting through social media, working within organizations, or communicating in healthcare settings, they still evaluate relationships based on what they give and what they receive. As communication continues to evolve through technology and changing social environments, Social Exchange Theory remains useful for explaining how individuals build trust, maintain connections, and decide whether relationships are worth continuing. A list of communications-based careers where social exchange theory is most prevalent includes, but is not limited to: Public relations specialist, human resources manager, sales representative, marketing manager, counselor or therapist, customer service representative, recruiter or talent acquisition specialist, negotiator or mediator, advertising executive, and social media manager.
