Influence of Peer Influence and Consumer Attitude on Green Purchasing Behavior: The Mediating Role of Decision-Making Style
This study demonstrates that among young adults, peer influence and consumer attitude significantly predict green purchasing behavior, with decision-making style acting as a crucial partial mediator that is further strengthened by brief sustainability interventions.

We often hear that people care about the planet, yet our shopping habits tell a different story. A person might genuinely believe in protecting the environment but still buy the cheaper, less sustainable option when standing in a store aisle. This gap between what we think and what we do is a central puzzle for researchers studying how we make choices. To understand it, scientists look at two main forces: the people around us and the way our own minds work. The first force is social pressure, or the subtle pull of what our friends and peers are doing and expecting. The second is our internal attitude, or how much we personally value green products. But knowing these factors exist is only half the story. The missing piece is the mental process we use to turn those feelings and social cues into an actual purchase. It is not just about caring; it is about how we decide.
A recent study by researcher Harshita Dedha explores this exact gap among young adults, specifically university students in India. The work focuses on how peer influence and personal attitude combine to shape green purchasing behavior, which is the act of buying products that are environmentally friendly. The study introduces a crucial middleman in this process: decision-making style. This refers to the characteristic way a person approaches a choice. Some people rely on careful, rational analysis, weighing facts and long-term benefits. Others might act more on impulse or intuition. The researcher wanted to see if the way a student thinks about a decision changes how much their friends' opinions or their own beliefs actually influence their final purchase. To test this, the study divided participants into two groups. One group watched a short educational video about sustainability, while the other group did not. This setup allowed the researcher to see if a brief lesson could strengthen the link between knowing what is right and actually doing it.
The results showed that both social pressure and personal attitude are powerful drivers of green buying. Students who felt their peers cared about the environment, or who personally felt positive about green products, were significantly more likely to buy them. However, the study found that these feelings do not automatically translate into action. Instead, the student's decision-making style acts as a filter. When a young adult processes information in a certain way, it helps turn their awareness and social motivation into a real purchase. The data suggested that this mental filter is only a partial explanation, meaning other factors are also at play, but it is a vital one. The way a person thinks about a choice determines whether their good intentions and social influences successfully cross the finish line.
The experiment revealed a striking difference between the two groups. The students who watched the sustainability video showed a stronger connection between their attitudes, their peers, and their purchasing behavior. In other words, the brief educational intervention helped them process the information more effectively, making it easier for their values to guide their actions. The group that did not watch the video still showed the same basic relationships, but the pathway from thought to action was less robust. This suggests that a short, focused lesson can sharpen the mental tools young people use to make sustainable choices. It does not just make them feel better about the environment; it helps them navigate the decision-making process so that their feelings lead to actual behavior.
These findings offer a clear path for educators and marketers who want to encourage sustainable habits. Simply telling young people to care about the planet or showing them that their friends care is not enough if their decision-making process gets in the way. The study implies that interventions should target how people think, not just what they think. By combining social messages with strategies that support rational or reflective decision-making, it may be possible to close the gap between caring and buying. The research confirms that while social norms and personal beliefs are essential, the mental habits we use to make choices are the bridge that turns those beliefs into the real-world impact of a green purchase.
